© 2002 by American Statistical Association. One of the pleasures of working as an applied statistician is the awareness it brings of the wide diversity of scientific fields to which our profession contributes critical concepts and methods. My own awareness was enhanced by accepting the invitation from the editors of JASA to serve as guest editor for this section of vignettes celebrating the significant contributions made by statisticians to the life and medical sciences in the 20th century. The goal of the project was not an encyclopedic catalog of all the major developments, but rather a sampling of some of the most interesting work. Of the 12 vignettes, 10 focus on particular areas of application: environmetrics, wildlife populations, animal breeding, human fertility, toxicology, medical diagnosis, clinical trials, environmental epidemiology, statistical genetics, and molecular biology. The two vignettes that begin the series focus more on methods that have had, or promise to have, impact across a range of subject matter areas: survival analysis and causal analysis.

View description>>

A compendium of algal bloom reports for marine and estuarine waters of New South Wales, Australia, for the period 1890-1999 is presented. The majority of blooms have been harmless water discolourations predominantly caused by the large heterotrophic dinoflagellate Noctiluca scintillans, or the filamentous cyanobacterium Trichodesmium erythraeum. Other harmless species that have bloomed include the dinoflagellates Gymnodinium sanguineum (= Akashiwo sanguinea) and Prorocentrum minimum, the surf diatom Anaulus australis, the coccolithophorid Gephyrocapsa oceanica and the ciliate Mesodinium rubrum. Species that have produced blooms and are potentially harmful to marine organisms include the silicoflagellate Dictyocha octonaria, the dinoflagellates Gonyaulax polygramma and Scrippsiella trochoidea and the diatoms Thalassiosira spp. and Chaetoceros spp. The toxic raphidophyte species Heterosigma akashiwo, Chattonella cf globosa and Haramonas sp., the dinoflagellates Gymnodinium galatheanum (= Karlodinium micrum), Dinophysis acuminata and Alexandrium catenella, and the diatoms Pseudo-nitzschia multiseries and P. australis have also been identified as bloom-forming species in these waters. Reports of algal blooms have apparently increased considerably since 1990 but the data may be biased because of the ad hoc nature of these reports. For this reason it is difficult to identify the cause(s) of this apparent increase in bloom frequency. Contributing factors may include the expansion in coastal settlements, an increase in awareness of environmental issues such as water quality, possible changes in anthropogenic nutrient input and/or the effects of large-scale oceanographic phenomena and/or climate change.

View description>>

Phytoplankton assemblages and their physicochemical environment were investigated during 1997-98 at a marine long-term coastal monitoring station off Sydney, Australia, and compared to those previously seen at this location. Phytoplankton blooms (significant population increases) coincided with episodic slope water intrusions (upwelling/uplifting) lasting 2-22 days and occurring from September to February. These blooms appeared to occur in response to slope water intrusions. The hydrological forcing variables of bottom- and surface-water nutrients and temperature, (including time-lagged data), were identified using Principal Component Analysis as those variables that explained 60% of the variability of the total phytoplankton biomass throughout the year. Phytoplankton blooms of similar frequency and magnitude to those seen in this study have been previously recorded. However, in contrast to earlier work, where a variety of taxa dominated throughout the year, the small diatom Thalassiosira partheneia generally dominated blooms in this study. In addition, presence/absence data for the heterotrophic dinoflagellate, Noctiluca scintillons, indicated a higher frequency of occurrence for this species than previously documented. N. scintillons was observed in 61% of samples collected throughout the year, being absent from only a few samples in the autumn and winter months. It is hypothesized that the shift in dominance from previously recorded bloom species to Thalassiosira could be a contributing factor to the increase in N. scintillons (a favored food source by N. scintillons) in NSW coastal waters. The reason for the recent dominance of these particular phytoplankters is unclear but may be related to physicochemical conditions such as a decrease in phosphate and oxidized nitrogen concentrations and warmer water temperatures experienced during our sampling period compared to previous years. A phytoplankton inventory is included as an Appendix. This includes what appear...

Severe asthma is characterized by increased airway smooth muscle (ASM) mass, due predominantly to ASM hyperplasia. Diverse stimuli, which include growth factors, plasma- or inflammatory cell-derived mediators, contractile agonists, cytokines, and extracellular matrix proteins, induce ASM proliferation. Mitogens act via receptor tyrosine kinase, G protein-coupled receptors, or cytokine receptors, to activate p21ras and stimulate two parallel signaling pathways in ASM cells, namely, the extracellular signal-regulated kinase (ERK) or the phosphatidylinositol 3-kinase (PI3K) pathways. ERK and PI3K regulate cell cycle protein expression and thus modulate cell cycle traversal. ERK activation and downstream effectors of PI3K, such as Rac1 and Cdc42, stimulate expression of cyclin D1, a key regulator of G1 progression in the mammalian cell cycle. In addition, PI3K activates 70-kDa ribosomal S6 kinase, an enzyme that also regulates the translation of many cell cycle proteins, including the elongation factor E2F. The present review examines the mitogens and critical signal transduction pathways that stimulate ASM cell proliferation. Further study in this area may reveal new therapeutic targets to abrogate ASM hyperplasia in diseases such as asthma and chronic obstructive pulmonary disease.

View description>>

Laser micropyrolysis gas chromatography-mass spectrometry is used for the analysis of paint, photocopier toner, and synthetic fiber materials to test the forensic potential of this emerging technology. It uses a laser microprobe to selectively target very small parts of the materials for GC-MS analysis. Whereas the paint and the toner samples were amenable to direct laser pyrolysis, the synthetic fibers proved transparent to the 1064 nm laser radiation. The difficulty with the fibers demonstrates that a specific laser wavelength may not be appropriate for all types of materials. Nevertheless, the fibers were able to be indirectly pyrolyzed by impregnation in a strongly absorbing graphite matrix. A vast array of hydrocarbon pyrolysates was detected from the different materials studied. Unique product distributions were detected from each sample and in sufficient detail to facilitate individual molecular characterization (i.e., molecular fingerprinting). The integrity of the laser data were confirmed by comparison to data obtained from the same samples by the more conventional pyroprobe pyrolysis GC-MS method. The high spatial resolution and selectivity of the laser method may be advantageous for specific forensic applications, however, further work may be required to improve the reproducibility of the data.

The phase transition properties of poly(ethylene oxide) (PEO), in aqueous solution, have been examined by differential scanning calorimetry (DSC) in the presence of NaCl (0-2 M). DSC studies show, for the first time, that the PEO phase transitions have an unusual line shape, the exact nature of which is dependent on NaCl concentration. The Tm (temperature of maximum apparent excess heat capacity) decreases with increasing [NaCl]. FT-IR experiments reveal that changes occur in the conformation of the C-O-C backbone of PEO, in the presence of 2 M NaCl, at the same temperature as the discontinuity in the apparent excess heat capacity function observed by DSC.

Using the exact theory of multipole expansions, we construct the two-dimensional Greens function for photonic crystals, consisting of a finite number of circular cylinders of infinite length. From this Greens function, we compute the local density of states ~LDOS!, showing how the photonic crystal affects the radiation properties of an infinite fluorescent line source embedded in it. For frequencies within the photonic band gap of the infinite crystal, the LDOS decreases exponentially inside the crystal; within the bands, we find ``hot and ``cold spots. Our method can be extended to three dimensions as well as to treating disorder and represents an important and efficient tool for the design of photonic crystal devices.

Exact theory of multipole expansions was used to construct two-dimensional Green's function and to compute the local density of states (LDOS) in photonic crystals. Spatial integration was also used to obtain the total density of states (DOS) for a finite structure. The analysis showed that the LDOS decreased exponentially inside the crystals for frequencies within photonic band gap.

In order to isolate genes coding for antigens of Neospora caninum which are recognised by the host immune system during a chronic murine infection, a cDNA library was immunoscreened with pooled sera from mice which survived three independent infections by N. caninum. Two new genes from N. caninum were isolated and expressed in Escherichia coli. The genes identified include one homologous to GRA1 of Toxoplasma gondii, plus another (NCP20) previously unknown in any taxon. Both genes encode small polypeptides which induced an IgG response in the mouse and were also recognised by IgG from a cow chronically infected with N. caninum. These results are consistent with the hypothesis that the polypeptides encoded by these genes are a target for the host immune system during chronic infections of N. caninum.

We show using PCR that psbC, atpA and petB genes are present in the plastid DNA minicircles from the dinoflagellate Amphidinium operculatum, extending the set of plastid genes identified from this organism. Unusually, the petB and atpA genes are located on the same minicircle. PCR using primers based on the "core" region round on all coding minicircles revealed the existence of a number of DNA minicircles with no apparent coding function. Northern analysis of total RNA from A. operculatum showed that the petB and atpA genes are represented on separate transcripts, despite being encoded in close proximity on the same minicircle. The possibility of transcript editing was investigated by RT-PCR, but psaA, psbA, psbB and atpB transcripts showed no evidence of editing, indicating that GUA can be used as an initiation codon in A. operculatum.

Mosquitoes of the Anopheles bancroftii group collected from Northern Australia and Papua New Guinea (PNG) were investigated for sequence variation within the ribosomal DNA ITS2. Wing fringe morphology originally used to identify members of this group was compared to genotypes identified by restriction fragment length polymorphism analysis (RFLP) and heteroduplex analysis (HDA) of the rDNA ITS2. Members of this group separated into four RFLP genotypes (A, B, C and D) with some genotypes displaying wing fringe polymorphisms. Heteroduplex analysis of the ITS2 within and between populations identified genotype A as containing two geographically separate ITS2 sequences: A1 from the Northern Territory of Australia and A2 from Queensland and the Western Province of PNG. Genotypes B and C and genotypes C and D were found sympatric and appeared to be evolving independently suggesting the possibility of cryptic species. Genotype C contained two ITS2 sequence types within the genome.

Evaluated the long-term stability of the Child Behavior Checklist (CBCL) in a longitudinal clinical sample of youth with attention deficit hyperactivity disorder (ADHD), testing the hypothesis that the CBCL scales will show stability over time. Participants were 105 Caucasian, non-Hispanic boys with ADHD between the ages of 6 and 17 assessed at baseline and at a 4-year follow-up. Stability of CBCL scales were computed for dimensional (intraclass correlation coefficients [ICCs], Pearson correlations) and dichotomized scale scores (kappa coefficients and odds ratios [ORs]). Evidence was found for stability of the categorical and dimensional types of scores, as demonstrated by statistically significant stability of the Pearson correlation coefficients, kappas, and ORs. The robust findings obtained from ICCs and kappa coefficients document substantial stability for CBCL scales over time within individuals with ADHD. These results support the informativeness of the CBCL as a useful measure of longitudinal course in clinical samples of youth with ADHD.

The effect of nickel on two classes of martensitic-type transformations in platinum systems has been studied. The first transformation is Ll[2] to DO[c]' in the Pt3Al system and the second is B2 to B 19 in the TiPt system. The microstructures after transformation in the two systems are very different. The product of the Pt[3]Al transformation has a twinned microstructure, typical of cubic-to-tetragonal transformations. The product of the TiPt transformation is lath-like, although the morphology can be altered using heat treatments. The parent phase in the TiPt system is not retained at room temperature, whereas the parent phase in the Pt[3]Al transformation can be stabilised to room temperature. A great variation in hardness and transformation temperature is seen in each system as the composition is varied about the stoichiometric ratio, which has the lowest hardness. The Pt[3]Al transformation temperature has been reported to range from around room temperature to 1000°C. The TiPt transformation temperature can range from 1000 to 1080°C. The effect of nickel additions on these alloys also has a marked effect on the parent and product phase stability, and hence the microstructure and resulting hardness. The effect on the Pt[3]Al phase is complex, as nickel appears to stabilise the parent phase. The hardness varied in the region of 350 to 500 HV[10]. For the TiPt phase, the hardness values were generally found to increase with the nickel additions increasing from 250 to about 600 HV[10]. The addition of 20 at.% nickel decreases the transformation temperature from around 1000°C to about 600°C.

Toughened glass panels used as a glazing material in multistorey buildings are known to fracture prematurely when they contain nickel sulfide inclusions as a result of the – phase recrystallisation in nickel sulfide. The kinetics of this recrystallisation were studied by differential scanning calorimetry (DSC) under isothermal and non-isothermal conditions. The recrystallisation was observed to be a two-step process with an induction period followed by the phase change. A two-stage kinetic model was used to estimate the recrystallisation time under ambient conditions. These values were found to correlate well with the observed time to failure for glass panels installed in multistorey buildings.

We study a piece-wise deterministic Markov process having jumps of i.i.d. sizes with a constant intensity and decaying at a constant rate (a special case of a storage process with a general release rule). Necessary and su4cient conditions for the process to be ergodic are found, its stationary distribution is found in explicit form. Further, the Laplace transform of the 6rst crossing time of a 6xed barrier by the process is shown to satisfy a Fredholm equation of second kind. Solution to this equation is given by exponentially fast converging Neumann series; convergence rate of the series is estimated. Our results can be applied to an important reliability problem.

A generic method was developed for calculating the band structure of two dimensional photonic crystals based upon the observation that such crystals could be considered as a stack of identical one-dimensional layers, each of which was a periodic diffraction grating. The scattering matrices of the gratings were used in combination with Bloch's theorem to determine the band structure of the crystal. The propagating modes and the evanescent states were studied and deduced that the reflection and transmission matrices corresponding to finite stack of gratings and construct the limit of the reflection matrix to deduce a semi-infinite space composed of stacked gratings.

Submicrometer LiCoO2 films were prepared with pulsed laser deposition (PLD) and rf sputtering using stoichiometric targets. The influences of both substrate material and annealing procedure on the polycrystalline microstructure of the LiCoO2 films were investigated. XRD analysis revealed strong preferential orientation: annealed films deposited with PLD had their (001) planes parallel to the surface, while rf sputtered films had their (110) planes in this orientation. The rf-film also developed the (003) reflection typical of PLD-films, but only after prolonged annealing at 600°C. The degree of preferential orientation is influenced significantly by the annealing procedure and only little by the substrate material and the thickness of the deposited film. Pulsed laser deposition on an rf-sputtered seed layer revealed the PLD-film reflections. Extinction of the otherwise dominating (003) reflection indicated a random cationic distribution in LiCoO2 with an NaCl-type structure. © 2001 The Electrochemical Society. All rights reserved.

Hormone replacement therapy (HRT) for perimenopausal women has been suggested to minimize the physical symptoms of menopause and improve mood and psychological functioning; however, the therapy remains controversial. In this study the effects of such therapy (comprising tablets, patches, and implants) on mood states was investigated within a sample of 70 perimenopausal women who were attending a family planning clinic within the Brisbane metropolitan area. On a battery of standardized questionnaires, including the General Health Questionnaire, the Profile of Mood States, the Eysenck Personality Questionnaire, and the Menstrual Distress Questionnaire, those 35 women who were using hormone replacement therapy prescribed by the clinic physician reported significantly lower scores on anxiety, insomnia, and somatic symptoms than did a comparable group of 35 untreated perimenopausal women. These findings provide some tentative support for the beneficial effects of the therapy on physical symptoms and psychological mood states related to the onset of menopause. Given increased life expectancy, there is a growing need for research into issues of aging.

Frequency figures of the fibre population on textile cinema seats were measured in Sydney, Australia, in winter. Sixteen seats were analysed from a very popular cinema complex, with 3025 fibres classified according to colour, generic class and fluorescence properties (100 grey–black cotton fibres only). The recovered fibres were mostly natural fibres (84%) with cotton the most common generic type (70%). On the contrary, man made fibres were relatively rare (15%) with rayon constituting the majority of these (51%). The most common colour/generic class combinations were grey–black cotton (33%) and blue cotton (30%) accounting for 63% of the total population. All other frequencies were below 5%, most below 1% using only the two properties of colour and generic class. Fluorescence properties were found to be very discriminating as far as grey–black cotton fibres were concerned. These features are considered and discussed and in particular, to emphasise the significance of fibres as evidence of contact.

Efforts to increase the practice of evidence-based psychotherapy in the United States have led to the formation of task forces to define, identify, and disseminate information about empirically supported psychological interventions. The work of several such task forces and other groups reviewing empirically supported treatments (ESTs) in the United States, United Kingdom, and elsewhere is summarized here, along with the lists of treatments that have been identified as ESTs. Also reviewed is the controversy surrounding EST identification and dissemination, including concerns about research methodology, external validity, and utility of EST research, as well as the reliability and transparency of the EST review process.

Acetylene reduction rates were measured in lagoonal sediments, cyanobacterial mats and limestone surfaces between 1991 and 1995 at many sites, depths and seasons; all the studied substrata contained cyanobacteria. The acetylene reduction/15N2 fixation ratio was measured for the different communities and varied between 1.8 and 4.8, depending on substratum. Fixation rates were 1.7 to 7 times higher during daylight compared to night-time rates. N2 fixation rates ranged from 0.4 to 3.9 mg N m-2 day-1 for the lagoonal sediment/mat communities, and the rate was about 2 mg N m-2 day-1 for the lagoonal limestone substrata. Total lagoonal benthic N2 fixation contributed 24.4% of the total nitrogen requirement for the benthic primary production of benthic communities of the lagoon. The input of N2 fixation by the microbial planktonic communities (including cyanobacteria) of the lagoon, which are highly productive, is unquantified but is likely to be large.

Tofu is a commonly consumed food in China. Tofu may interfere with lead absorption and retention because of its high calcium content. In this observational study, the authors examined whether dietary tofu intake was associated with blood lead levels among young adults in Shenyang, China. The analyses included 605 men and 550 women who completed baseline questionnaires and had blood lead measurements taken in 1996-1998 as part of a prospective cohort study on reproductive health. Mean blood lead levels were 13.2 mug/dl in men and 10.1 mug/dl in women. Blood lead levels were negatively associated with tofu intake in both genders. A linear trend test showed a 3.7% (0.5-mug/dl) decrease in blood lead level with each higher category of tofu intake (p = 0.003). The highest tofu intake group (greater than or equal to 750 g/week) had blood lead levels 11.3% lower (95% confidence interval: 4.1, 18.0) than those of the lowest tofu intake group (< 250 g/week). In all regression models, data were adjusted for gender, age, height, body mass index, district, cigarette smoking, alcohol drinking, education, occupation, use of vitamin supplements, season, and dietary intake of meat, fish, vegetables, eggs, and milk. In conclusion, the authors found a significant inverse dose-response relation between tofu consumption and blood lead levels in this Chinese population.

Ninhydrin developed ®ngerprints can be enhanced by treatment with a zinc or cadmium salt. The resulting ®ngerprint luminescence has been attributed to the induced coplanarity of the bicyclic indanedione rings of Ruhemann's purple due to complexation with the metal ions. This paper explores whether this effect also occurs in the 1,8-diaza-9-¯uorenone (DFO)- amino acid adduct (1), formed from the reaction of DFO with amino acids. Molecular modeling studies of (1) indicate a relatively small out-of-plane angle of 248. 1H NMR studies indicate (1) is asymmetric about the C2 axis in contrast to what has been previously reported. Little, if any, enhancement of luminescence was observed with Zn, Cd, Ru or Eu treated DFO developed latent ®ngerprints. This lack of enhancement was also borne out by solution luminescence studies. Given this lack of enhancement of luminescence, solutions of (1) and the four metal ions above were analyzed by electrospray mass spectrometry (ESMS). This indicated the formation of predominantly 1:1 complexes of (1) with both Zn and Cd, and the 2:1 complex with ruthenium. No evidence of a Eu complex was found by ESMS.

We describe a method for assessing dose-response effects from a series of case-control and cohort studies in which the exposure information is interval censored. The interval censoring of the exposure variable is dealt with through the use of retrospective models in which the exposure is treated as a multinomial response and disease status as a binary covariate. Polychotomous logistic regression models are adopted in which the dose-response relationship between exposure and disease may be modeled in a discrete or continuous fashion. Partial conditioning is possible to eliminate some of the nuisance parameters. The methods are applied to the motivating study of the relationship between chorionic villus sampling and the occurrence of terminal transverse limb reduction.

The problem of testing a dose-response relationship in the presence of exchangeably correlated binary data has been addressed using a variety of models. Most commonly used approaches are derived from likelihood or generalized estimating equations and rely on large-sample theory to justify their inferences. However, while earlier work has determined that these methods may perform poorly for small or sparse samples, there are few alternatives available to those faced with such data. We propose an exact trend test for exchangeably correlated binary data when groups of correlated observations are ordered. This exact approach is based on an exponential model derived by Molenberghs and Ryan (1999) and Ryan and Molenberghs (1999) and provides natural analogues to Fisher's exact test and the binomial trend test when the data are correlated. We use a graphical method with which one can efficiently compute the exact tail distribution and apply the test to two examples.

Human teratogens often manifest themselves through a broad spectrum of adverse effects. Although often not serious when considered individually, such outcomes taken together may represent a syndrome that can lead to serious developmental problems. Accordingly, studies that investigate the effect of human teratogens on fetal development typically record the presence or absence of a multitude of abnormalities, resulting in the data of multivariate binary form for each infant. Such studies typically have three objectives: (1) estimate an overall effect of exposure across outcomes, (2) identify subjects having the syndrome, and (3) identify those outcomes that constitute the syndrome so that doctors know what to look for when diagnosing the syndrome in other exposed newborns. This article proposes the use of a logistic regression model with crossed random effect structure to address all three questions simultaneously. We use the proposed models to analyze data from a study investigating the effects of in utero antiepileptic drug exposure on fetal development.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is expressed by in vitro activated natural killer (NK) cells, but the relevance of this observation to the biological function of NK cells has been unclear. Herein, we have demonstrated the in vivo induction of mouse TRAIL expression on various tissue NK cells and correlated NK cell activation with TRAIL-mediated antimetastatic function in vivo. Expression of TRAIL was only constitutive on a subset of liver NK cells, and innate NK cell control of Renca carcinoma hepatic metastases in the liver was partially TRAIL dependent. Administration of therapeutic doses of interleukin (IL)-12, a powerful inducer of interferon (IFN)-gamma production by NK cells and NKT cells, upregulated TRAIL expression on liver, spleen, and lung NK cells, and IL-12 suppressed metastases in both liver and lung in a TRAIL-dependent fashion. By contrast, alpha -galactosylceramide (alpha -GalCer), a powerful inducer of NKT cell IFN-gamma and IL-4 secretion, suppressed both liver and lung metastases but only stimulated NK cell TRAIL-mediated function in the liver. TRAIL. expression was not detected on NK cells from IFN-gamma -deficient mice and TRAIL-mediated antimetastatic effects of IL-12 and a-GalCer were strictly IFN-gamma dependent. These results indicated that TRAIL induction on NK cells plays a critical role in IFN-gamma -mediated antimetastatic effects of IL-12 and alpha -GalCer.

With microsensors, we measured the steady-state microprofiles of O2, pH and Ca2+ on the topside of young segments of Halimeda discoidea, as well as the surface dynamics upon light-dark shifts. The effect of several inhibitors was studied. The steady-state measurements showed that under high light intensity, calcium and protons were taken up, while O2 was produced. In the dark, O2 was consumed, the pH decreased to below seawater level and Ca2+ uptake was reduced to 50%. At low light intensity (12 μmol photons m-2 s-1), Ca2+ efflux was observed. Upon light-dark shifts, a complicated pattern of both the pH and calcium surface dynamics was observed. Illumination caused an initial pH decrease, followed by a gradual pH increase: this indicated that the surface pH of H. discoidea is determined by more than one light-induced process. When photosynthesis was inhibited by dichlorophenyl dimethyl urea (DCMU), a strong acidification was observed upon illumination. The nature and physiological function of this putative pump is not known. The calcium dynamics followed all pH dynamics closely, both in the presence and absence of DCMU. The Ca-channel blockers verapamil and nifedipine had no effect on the Ca2+ dynamics and steady-state profiles. Thus, in H. discoidea, calcification is not regulated by the alga, but is a consequence of pH increase during photosynthesis. Acetazolamide had no effect on photosynthesis, whereas ethoxyzolamide inhibited photosynthesis at higher light intensities. Therefore, all carbonic anhydrase activity is intracellular. Carbonic anhydrase is required to alleviate the CO2 limitation. Calcification cannot supply sufficient protons and CO2 to sustain photosynthesis.

A comprehensive genetic analysis of 60 Mycoplasma sp. bovine group 7 isolates from different geographic origins and epidemiological settings is presented. Twenty-four isolates were recovered from the joints of calves during sporadic episodes of poly-arthritis in geographically distinct regions of Queensland and New South Wales, Australia, including two clones of the type strain PG5O. A further three Australian isolates were also recovered from the tympanic bulla, retropharyngeal lymph node and the lung and another three isolates had unconfirmed histories. Six isolates originated from Germany, Portugal, Nigeria, and France. Twenty-four epidemiologically related isolates of Mycoplasma sp. bovine group 7 were recovered from multiple tissue sites and body fluids of infected calves with polyarthritis, mastitic milk, and from the stomach contents, lung and liver from aborted foetuses in three large, centrally managed dairy herds in New South Wales, Australia. Restriction endonuclease analysis (REA) of genomic DNA differentiated 29 Cfol profiles among these 60 isolates and grouped all 24 epidemiologically related isolates in a defined pattern showing a clonal origin. Three isolates of this clonal cluster were recovered from mastitic milk and the synovial exudate of clinically-affected calves and appeared sporadically for periods up to 18 months after the initial outbreak of polyarthritis indicating a persistent, close association of the organism with cattle in these herds. The Cfol profile representative of the clonal cluster was distinguishable from profiles of isolates recovered from multiple, unrelated cases of polyarthritis in Queensland and New South Wales and from other countries. All 24 isolates from the clonal cluster possessed a plasmid (pBG7AU) with a molecular size of 1022 bp. DNA sequence analysis of pBG7AU identified two open reading frames sharing 81 and 99% DNA sequence similarity with hypothetical replication control proteins A and B respectively, previo...

The absorption and extinction spectra of Ge nanocrystals in silica formed by ion implantation are studied using photothermal deflection and transmission spectroscopies. It is found that scattering makes a significant contribution to the extinction spectrum, damping the spectral features and resulting in a Rayleigh scattering-like omega4 dependence. In contrast, the spectra measured by photothermal deflection clearly show features such as the E1/E1 + Delta1 transitions. The Tauc gap is extracted to be ~0.7±0.1 eV.

Ge nanocrystals formed in silica by implantation with 1.0 MeV Ge ions and subsequent annealing at 1100°C were characterised by transmission electron microscopy and Raman spectroscopy. The nanocrystals were found to be approximately spherical in shape and to have a structure consistent with that of bulk Ge. The average size of the crystallites increased with increasing fluence and for a fluence of 1Ã1017 Ge cmâ2 the size varied from 2.5 to 12 nm. The nonlinear optical response of the material was measured at a wavelength of 800 nm using degenerative four wave mixing and z-scan techniques. The former provided information about the magnitude and temporal response of the nonlinearity whilst the latter provided information about the operative mechanism. The magnitude of the nonlinear refractive index, |n2|, was shown to be more than three-orders of magnitude larger than that of pure silica and to have a relaxation time of the order of picoseconds. The mechanism causing this nonlinear response is shown to be absorptive and to increase with increasing implant fluence as a consequence.

Alternative approaches to hedging swaptions are explored and tested by simulation. Hedging methods implied by the Black swaption formula are compared with a lognormal forward LIBOR model approach encompassing all the relevant forward rates. The simulation is undertaken within the LIBOR model framework for a range of swaptions and volatility structures. Despite incompatibilities with the model assumptions, the Black method performs equally well as the LIBOR method, yielding very similar distributions for the hedging prot and loss | even at high rehedging frequencies. This result demonstrates the robustness of the Black hedging technique and implies that | being simpler and generally better understood by nancial practitioners | it would be the preferred method in practice.

Numerous studies have established the importance of picoplankton (microorganisms of ≤2 μ,m in length) in energy flow and nutrient cycling in marine oligotrophic environments, and significant effort has been directed at identifying and isolating heterotrophic picoplankton from the world's oceans. Using a method of diluting natural seawater to extinction followed by monthly subculturing for 12 months, a bacterium was isolated that was able to form colonies on solid medium. The strain was isolated from a 105 dilution of seawater where the standing bacterial count was 3.1 × 105 cells ml-1. This indicated that the isolate was representative of the most abundant bacteria at the sampling site, 1.5 km from Cape Muroto, Japan. The bacterium was characterized and found to be ultramicrosized (less than 0.1 μm3), and the size varied to only a small degree when the cells were starved or grown in rich media. A detailed molecular (16S rRNA sequence, DNA-DNA hybridization, G+C mol%, genome size), chemotaxonomic (lipid analysis, morphology), and physiological (resistance to hydrogen peroxide, heat, and ethanol) characterization of the bacterium revealed that it was a strain of Sphingomonas alaskensis. The type strain, RB2256, was previously isolated from Resurrection Bay, Alaska, and similar isolates have been obtained from the North Sea. The isolation of this species over an extended period, its high abundance at the time of sampling, and its geographical distribution indicate that it has the capacity to proliferate in ocean waters and is therefore likely to be an important contributor in terms of biomass and nutrient cycling in marine environments.

We consider the connections between sums of spherical wave functions over lattices, layers, and lines. The differences between sums over lattices and those over a doubly periodic constituent layer are expressed in terms of series with exponential convergence. Correspondingly, sums over the layer can be regarded as composed of a sum over a central line, and another sum over displaced lines exhibiting exponential convergence. We exhibit formulas which can be used to calculate accurately and efficiently sums of spherical waves over lattices, layers, and lines, which in turn may be used to construct quasiperiodic Green’s functions for the Helmholtz equation, of use in scattering problems for layers and lines of spheres, and for finding the Bloch modes of lattices of spheres. We illustrate the numerical accuracy of our expressions.

We have identified three Arabidopsis genes with GAMYB-like activity, AtMYB33, AtMYB65, and AtMYB101, which can substitute for barley (Hordeum vulgare) GAMYB in transactivating the barley alpha-amylase promoter. We have investigated the relationships between gibberellins (GAs), these GAMYB-like genes, and petiole elongation and flowering of Arabidopsis. Within 1 to 2 d of transferring plants from short- to long-day photoperiods, growth rate and erectness of petioles increased, and there were morphological changes at the shoot apex associated with the transition to flowering. These responses were accompanied by accumulation of GAs in the petioles (GA(1) by 11-fold and GA(4) by 3-fold), and an increase in expression of AtMYB33 at the shoot apex. Inhibition of GA biosynthesis using paclobutrazol blocked the petiole elongation induced by long days. Causality was suggested by the finding that, with GA treatment, plants flowered in short days, AtMYB33 expression increased at the shoot apex, and the petioles elongated and grew erect. That AtMYB33 may mediate a GA signaling role in flowering was supported by its ability to bind to a specific 8-bp sequence in the promoter of the floral meristem-identity gene, LEAFY, this same sequence being important in the GA response of the LEAFY promoter. One or more of these AtMYB genes may also play a role in the root tip during germination and, later, in stem tissue. These findings extend our earlier studies of GA signaling in the Gramineae to include a dicot species, Arabidopsis, and indicate that GAMYB-like genes may mediate GA signaling in growth and flowering responses.

Scanning electron microscopy and cathodoluminescence (CL) in spot and depth-profiling modes were used to evaluate the in-plane and in-depth uniformity of light emission from InGaN/GaN quantum well (QW) structures. The structures were grown by MOCVD on sapphire with a low-temperature (LT) GaN buffer. Depth-profiling CL investigations were used to identify the observed CL emissions, which show a complicated in-depth evolution. The influence of a LT GaN buffer on the structural and optical properties of the GaN/sapphire interface is discussed.

We report the results of low-temperature photoluminescence, room-temperature cathodoluminescence (CL) and scanning CL and electron microscopy of self-organized CdTe/ZnTe quantum dot (QD) structure. The in-depth profiling CL investigations were used to identify the microscopic origin of the CL emissions observed at 2.13, 2.0–2.1 and 2.25 eV. In particular, we distinguish between CL emissions originating from the QD region of the structure and from the underlying buffer layers. Based on these measurements we assign the 2.13 eV CL band to the wetting layer and the 2.0–2.1 eV band to the QD emission. From the study of the in-plane and in-depth CL characteristics we demonstrate large in-plane fluctuations of the CL intensity and discuss their origin.

We have examined multiple quantum well AlGaN/GaN structures with several quantum wells of varying widths. The structures had strain-free quantum wells and strained barriers. Strong piezoelectric fields in these structures led to a large red shift of the PL emission energies and long decay times were also observed. While the peak energies could be modelled using the effective mass approximation, the calculated free exciton radiative lifetimes were much shorter than those observed in experiments, indicating an alternative recombination mechanism, tentatively attributed to localised excitons. Cathodoluminescence depth profiling revealed an unusually small penetration range of electrons suggesting that electron-hole pairs preferentially remain within the multiple quantum well region due to the existing electric fields. Spatial fluctuations of the cathodoluminescence intensity were also observed.

The rat tail ischaemia-reperfusion model of acute hyperalgesia described by Gelgor et al. (Pain 24 (1986) 251) has been investigated pharmacologically and electrophysiologically. Despite the advantages of this reusable animal model, biochemical changes associated with the behavioural response have not been determined. After injury ± subcutaneous diclofenac pretreatment, we investigated the behavioural response (changes to thermally-induced tail flick latency) and measured diclofenac, prostaglandin E2, 6-keto-prostaglandin F1α and thromboxane B2 concentrations in the tail, spinal cord and brain. Subcutaneous injection of 40 mg kg-1 diclofenac sodium abolished the hyperalgesic response, suppressed the increased eicosanoid production in the tail, inhibited eicosanoid synthesis in the brain, but gave equivocal effects on eicosanoid concentrations in the spinal cord. Injection of 10 and 20 mg kg-1 diclofenac reduced the duration of hyperalgesia but did not abolish the behavioural response. Diclofenac concentrations in all three tissues were similar, being ∼5-10% of the corresponding plasma concentrations. We propose that both central and peripheral mechanisms are associated with the hyperalgesia and that the findings lend indirect support to a central action for non-steroidal anti-inflammatory drugs. © 2001 International Association for the Study of Pain.

Discussed the initial findings from the recently published, National Institute of Mental Health-sponsored Multimodal Treatment Study (MTA) of attention deficit hyperactivity disorder (ADHD). These findings can be summarized as follows: Medical management alone was found to be significantly more effective for the core symptoms of ADHD as compared to behavioral treatment alone and routine (community) care, and behavioral treatment did not significantly improve outcome when combined with medical treatment. In discussing these findings, it is important to be explicit about the research questions the study was and was not designed to answer. The MTA study provided useful information regarding the question, "Does a very intensive form of behavioral treatment deliver greater benefits than the less intensive forms of behavioral treatment investigated in prior studies ?" but little insight on the question, "What type of treatment by what type of therapist is most effective in dealing with what specific problems among specific children with ADHD?" It is suggested that the clearest finding from the MTA study is that the effectiveness of psychosocial intervention for ADHD hinges on the degree to which a broad range of treatment ingredients are considered, carefully selected, matched, and tailored to the individual needs of each child with the disorder, and implemented and monitored over the long term.

Objective: To investigate social impairment in girls with attention-deficit/hyperactivity disorder (ADHD), compare the social functioning of boys and girls with ADHD, and explore the association between social dysfunction and conditions comorbid with ADHD. Method: Four groups of index children were studied: 267 children (127 girls) with ADHD and 234 non-ADHD comparison children (114 girls). Groups were compared on social functioning, psychopathology, and demographic characteristics. Results: Girls with ADHD manifested significant deficits in interpersonal functioning compared with girls without ADHD and evidenced a similar degree of social impairment compared with boys with ADHD. ADHD and associated comorbid disorders were significant correlates of specific domains of social dysfunction in boys and girls with ADHD. Conclusions: Interpersonal deficits are a major correlate of ADHD, irrespective of gender, and appear to stem from the behaviors associated with ADHD as well as behaviors characteristic of conditions comorbid with ADHD.

Anxiety may be more transient in children and adolescents than in adults. The present study involves a longitudinal design enabling the investigation of the continuity/discontinuity of self-reported anxiety in children and adolescents. A sample of 68 children was followed over 3 years. Results indicate that, on the whole, self-reported anxiety decreased over time. This was true for overall anxiety and its sub-types, with the exception of social concerns/concentration, which did not decrease over time. Consistent with past research involving normal fear, girls and younger children were found to score higher on anxiety than boys and older children did. However, those groups scoring higher at inception also demonstrated the most marked decreases over the 3-year period. In addition to the changes found over time, the data indicated continuity in anxiety such that levels of anxiety at inception were significant predictors of follow-up anxiety, although only a small amount of variance was shared. The authors concluded that adult models of anxiety cannot be applied to youth and that future research should investigate the contribution of contextual factors to the development of anxiety in children.

Potentiometric titration in 95% methanol (I = 0.1 mol dm-3, Et4NClO4) has been employed to investigate the effect of N-methylation and N-benzylation of 1,4,10,13-tetraoxa-7,16-diazacyclooctadecane 1 on the binding of all three rings to cobalt(II), nickel(II), copper(II), zinc(II), cadmium(II), silver(I) and lead(II). The results show that enhanced selectivity for silver(I) is exhibited by the di-N-benzylated derivative 3 while the analogous dimethylated derivative 2 discriminates for both silver(I) and lead(II). The crystal structures of [Ag(1)]PF6, [Ag(2)]PF 6, [Ag(3)]PF6 and [Pb(1)(NO3)2] have been determined. In the silver complexes the NH hydrogens of 1 and the N-methyl and N-benzyl substituents of the dialkylated derivatives 2 and 3 were found to lie on the same side of the mean donor planes of the co-ordinated macrocycles ('cis' arrangements). Density functional theory has been employed to model the silver complexes in both their energy-minimised 'cis' and 'trans' configurations. In accordance with the X-ray evidence, the calculations predict that the 'cis' arrangement is the more stable in each case. The crystal structure of the lead complex of 1 shows a 'trans' arrangement of its NH groups. © The Royal Society of Chemistry 2001.

CLIC1 (NCC27) is a member of the highly conserved class of chloride ion channels that exists in both soluble and integral membrane forms. Purified CLIC1 can integrate into synthetic lipid bilayers forming a chloride channel with similar properties to those observed in vivo. The structure of the soluble form of CLIC1 has been determined at 1.4-Angstrom resolution. The protein is monomeric and structurally homologous to the glutathione S-transferase superfamily, and it has a redox-active site resembling glutaredoxin. The structure of the complex of CLIC1 with glutathione shows that glutathione occupies the redox-active site, which is adjacent to an open, elongated slot lined by basic residues. Integration of CLIC1 into the membrane is likely to require a major structural rearrangement, probably of the N-domain (residues 1-90), with the putative transmembrane helix arising from residues in the vicinity of the redox-active site. The structure indicates that CLIC1 is likely to be controlled by redox-dependent processes.

The earliest stage of cell division in bacteria is the formation of a Z ring, composed of a polymer of the FtsZ protein, at the division site. Z rings appear to be synthesized in a bi-directional manner from a nucleation site (NS) located on the inside of the cytoplasmic membrane. It is the utilization of a NS specifically at the site of septum formation that determines where and when division will occur. However, a Z ring can be made to form at positions other than at the division site. How does a cell regulate utilization of a NS at the correct location and at the right time? In rod-shaped bacteria such as Escherichia coli and Bacillus subtilis, two factors involved in this regulation are the Min system and nucleoid occlusion. It is suggested that in B. subtilis, the main role of the Min proteins is to inhibit division at the nucleoid-free cell poles. In E. coli it is currently not clear whether the Min system can direct a Z ring to the division site at mid-cell or whether its main role is to ensure that division inhibition occurs away from mid-cell, a role analogous to that in B. subtilis. While the nucleoid negatively influences Z-ring formation in its vicinity in these rod-shaped organisms, the exact relationship between nucleoid occlusion and the ability to form a mid-cell Z ring is unresolved. Recent evidence suggests that in B. subtilis and Caulobacter crescentus, utilization of the NS at the division site is intimately linked to the progress of a round of chromosome replication and this may form the basis of achieving co-ordination between chromosome replication and cell division.

View description>>

Progress in solving the long-standing puzzle of how a cell coordinates chromosome replication with cell division is significantly aided by the use of synchronous cell populations. Currently three systems are employed for obtaining such populations: the Escherichia coli `baby machine, the developmentally-controlled cell cycle of Caulobacter crescentus, and Bacillus subtilis germinated and outgrowing spores. This review examines our current understanding of the relationship between replication and division and how the use of B. subtilis outgrowing spores and, more recently its combination with immunofluorescence microscopy, has contributed significantly to this important area of biology. About 20 years ago, and also more recently, this system was used to show convincingly that termination of DNA replication is not essential for a central septum to form, raising the possibility that the early stages of division occur well before termination. It has also been demonstrated that there is no major synthesis of the division initiation proteins, FtsZ and DivIB, linked to initiation, progression or completion of the first round of chromosome replication accompanying spore outgrowth. This has led to the suggestion that the primary link between chromosome replication and cell division at midcell is not likely to occur through a control over the levels of these proteins. Very recent work has employed a combination of the use of B. subtilis outgrowing spores with immunofluorescence microscopy to investigate the relationship between midcell Z ring assembly and the round of chromosome replication linked to it. The results of this work suggest a role for initiation and progression into the round of replication in blocking midcell Z ring formation until the round is complete or almost complete, thereby ensuring that cell division occurs between two equally-partitioned chromosomes.

A mathematical model was used to simulate interannual patterns of biomass accumulation within benthic microbial mats of two Antarctic lakes. Lakes Hoare and Vanda are in the Dry Valley region of Southern Victoria Land, and are both perennially ice covered. The model combines experimentally derived observations of light/photosynthesis relationships and rates of respiration of mats from a range of depths in these lakes, with data on incident radiation and the optical properties of the ice and water column. The model was used to estimate daily and annual production and, using measured carbon content, the potential vertical accumulation of the mats over a year. An annual pattern of photosynthesis was predicted for both lakes, with net production from October to February and net respiration at other times. Predicted rates and patterns of net photosynthesis were remarkably similar in the two lakes, despite differences in light climate; the ice of Lake Hoare transmits 1-4% incident radiation, whereas that of Lake Vanda transmits up to 20%. Maximum daily rates of 15-20 μg carbon cm-2 were predicted to occur at approximately 10 m depth in both lakes. Maximum annual rates of carbon fixation (at 10-12 m depth) in both lakes were c. 1.2 mg carbon cm-2 equating to approximately 0.1-4 mm vertical accumulation of mat each year. Experimental studies of microbial mats in the lakes revealed horizontal laminations of similar thickness to model estimates, supporting the hypothesis that these were annual layers. Differences between model estimates and observations were found in deeper water in Lake Vanda, where considerably more material accumulated than was predicted.

Significant changes occur in intestinal epithelial cells after infection with enteropathogenic Escherichia coli (EPEC), However, it is unclear whether this pathogen alters rates of apoptosis, By using: a naturally occurring weaned rabbit infection model, we determined physiological levels of apoptosis in rabbit ileum and ileal Peyer's patches (PP) and compared them to those found after infection with adherent rabbit EPEC (REPEC O103), Various REPEC O103 strains were first tested in vitro for characteristic virulence features. Rabbits were then inoculated with the REPEC O103 strains that infected cultured cells the most efficiently. After experimental infection, intestinal samples were examined by light and electron microscopy, Simultaneously, ileal apoptosis was assessed by using terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick end labeling (TUNEL) and caspase 3 assays and by apoptotic cell counts based on morphology (hematoxylin-and-eosin staining). The highest physiological apoptotic indices were measured in PP germinal centers (median = 14.7%), followed by PP domed villi (8.1%), tips of absorptive villi (3.8%), and ileal crypt regions (0.5%), Severe infection with REPEC O103 resulted in a significant decrease in apoptosis in PP germinal centers (determined by TUNEL assay; P = 0.01), in the tips of ileal absorptive villi (determined by H&E staining; P = 0.04), and in whole ileal cell lysates (determined by caspase 3 assay; P = 0.001). We concluded that REPEC O103 does not promote apoptosis, Furthermore, we cannot rule out the possibility that REPEC O103, in fact, decreases apoptotic levels in the rabbit ileum.

Background: The frequency of major malformations, growth retardation, and hypoplasia of the midface and fingers, known as anticonvulsant embryopathy, is increased in infants exposed to anticonvulsant drugs in utero. However, whether the abnormalities are caused by the maternal epilepsy itself or by exposure to anticonvulsant drugs is not known. Methods: We screened 128,049 pregnant women at delivery to identify three groups of infants: those exposed to anticonvulsant drugs, those unexposed to anticonvulsant drugs but with a maternal history of seizures, and those unexposed to anticonvulsant drugs with no maternal history of seizures (control group). The infants were examined systematically for the presence of major malformations, signs of hypoplasia of the midface and fingers, microcephaly, and small body size. Results: The combined frequency of anticonvulsant embryopathy was higher in 223 infants exposed to one anticonvulsant drug than in 508 control infants (20.6 percent vs. 8.5 percent; odds ratio, 2.8; 95 percent confidence interval, 1.1 to 9.7). The frequency was also higher in 93 infants exposed to two or more anticonvulsant drugs than in the controls (28.0 percent vs. 8.5 percent; odds ratio, 4.2; 95 percent confidence interval, 1.1 to 5.1). The 98 infants whose mothers had a history of epilepsy but took no anticonvulsant drugs during the pregnancy did not have a higher frequency of those abnormalities than the control infants. Conclusions: A distinctive pattern of physical abnormalities in infants of mothers with epilepsy is associated with the use of anticonvulsant drugs during pregnancy, rather than with epilepsy itself.

The multiple causes and multiple consequences of mammalian heart failure make it an attractive proposition for analysis using gene array technology, especially where the failure is idiopathic in nature. However, gene arrays also hold potential artefacts, particularly when gene expression levels are low, and where changes in expression levels are modest. Also, at present, the number of genes available on arrays is not large enough to prevent potential sampling deficiencies. Thus, it may not be wise to place too much reliance on quantitative interpretations of gene array data. Also, recently doubts were raised about the qualitative reliability of array genes. Electrophoretic methods are slow, cumbersome and complex but they can provide confirmation that the trends and numbers arising from the new gene arrays are reliable. In this overview, we compare gene array data with data from protein activity assays such as zymograms, Western blots, two-dimensional electrophoresis, and immunohistochemistry. Similar or complementary data from the same heart tissues analyzed by either microarrays or macroarrays can be reassuring to those interested in reliable molecular analyses of normal and failing hearts. Similar principles will apply to other tissues and cells.

This study investigated fingerprint development on five different polymer substrates using vacuum metal deposition (VMD). The conditions required for optimum development are shown to depend on a number of factors. No one set of conditions will result in good development in all situations. Polymer type has been confirmed as a major factor in determining the types of development that will occur and the optimum VMD conditions required. For more consistently successful VMD development, polymer type should be determined before selecting conditions. While polymer type is a key factor in determining optimum development conditions, there may be variation of the optimum conditions within a polymer type, most likely due to the presence of additives in the plastic. The heaviness of a latent print, i.e. amount of residue that constitutes the print, also affects the VMD conditions required. The donor, manner of deposition, and age of a print affect the heaviness of the deposit. The heavier the print, the higher the gold count necessary for successful VMD development. The occurrence of ‘empty prints’ (i.e. zinc deposition on the general background but not on or between the print ridges) was found to be related to polymer type and print heaviness. Heavy prints on PVC and PET are the most likely to be ‘empty’ after VMD treatment. The development of empty prints may be due to the diffusion of print residue into the print valleys. Pre-treatment with cyanoacrylate fuming was also found to affect VMD development. In particular, it was shown that cyanoacrylate pre-treatment was beneficial for print development on PET and PVC. The results of this study were used to formulate guidelines for use as an aid by laboratories using VMD in casework.

Vacuum metal deposition (VMD) is an established technique for the development of latent fingerprints on non-porous surfaces. VMD has advantages over cyanoacrylate fuming, especially in circumstances where prints are old, have been exposed to adverse environmental conditions, or are present on semi-porous surfaces. Under normal circumstances, VMD produces `negative prints as zinc deposits onto the background substrate and not the print ridges themselves. A phenomenon of `reverse development, when zinc deposits onto the print ridges and not the background, has been reported by many authors but its causes have not been conclusively identified. Four plastic substrates were used in this study and these could be easily divided into two groups based on the types of development observed as the amount of deposited gold was increased. On group I plastics, identified as low-density polyethylene (LDPE), normal development then reverse development and finally no development resulted with increasing gold. On group II plastics, identified as high-density polyethylene (HDPE), normal development then over-development and finally poor-quality normal development resulted with increasing gold. Our results suggest that the difference between these plastic types causes variations in the gold film structure which in turn dictates the nature of the zinc deposition. On group I plastics, the structure and thickness of the gold film has been identified as the critical factor in the occurrence of normal or reverse development. Thin gold films on plastic substrates form small `clusters (or agglomerates) rather than the atoms being uniformly spread over the surface. The size and shape of these clusters is critical. Once the clusters reach a certain morphology, they no longer act as nucleation sites for zinc, and hence, zinc will not deposit onto the substrate.

Infrared (IR) spectra of different varieties of document papers were collected with the use of attenuated total reflectance (ATR, 4000-650 cm-1, eight paper varieties) and diffuse reflectance (DRIFTS, 9000-2500 cm-1, six paper varieties) techniques. The spectral data were classified by the application of soft independent modeling of class analogies (SIMCA), using principal components analysis (PCA) to estimate the distance of separation between the different classes of paper samples and discriminant analysis (DA) to obtain a probabilistic classification. The use of DA on spectral data needed a preliminary data reduction step, either by PCA-decomposition of spectra or the selection of discrete spectral features having maximum discriminating ability. The aim of this research was to evaluate these data-reduction techniques and compare the discriminating power of these two spectral techniques (DRIFTS and ATR) by the application of PCA and DA. The use of PCA scores as DA variables provided the best resolution (100% correct classification) for the DRIFTS spectra, while PCA on the ATR spectra resulted in the best discrimination, separating 67.86% paper pairs completely with the use of cross-validation. The results of this study reemphasize that infrared spectroscopy coupled with multivariate statistical methods of analysis could provide a powerful discriminating tool for the forensic questioned document examiner.

Although evidence is accumulating on the immediate or short-term efficacy of cognitive-behavioural strategies in the treatment of school refusal, no studies have been reported on the long-term efficacy of this treatment approach. An earlier randomized clinical trial conducted by the authors demonstrated the efficacy of a manual-based cognitive-behavioural treatment program for school refusal relative to waiting list controls. We now report findings of a 3- to 5-year follow-up investigation of the treatment group. In general, results support the long-term efficacy of the treatment program, with children showing maintenance of improvements in school attendance and school adjustment. Methodological limitations of the follow-up investigation are emphasized. © 2001 Taylor & Francis Group, LLC.

School refusal is a complex and challenging problem for school personnel and mental health professionals. However, school refusal behaviour can be successfully treated provided there has been a sound assessment. We outline an hypothesis-testing, multi-informant assessment approach that incorporates diagnostic interviewing, functional analysis assessment, self-report measures, parent/teacher checklists and review of school attendance records. Further, it is shown how assessment information facilitates individual treatment planning for the school-refusing child and family. We also discuss the issue of graduated versus rapid school return arrangements. Copyright © 2001 John Wiley & Sons, Ltd.

PURPOSE: Spontaneous abortion (SAB), the most common adverse pregnancy outcome, affects similar to 15% of clinically recognized pregnancies. Except for advanced maternal age and smoking, there are not well-established risk factors for SAB. Animal models associate increased fetal resorption or abortion with exposure to the pesticide dichlorodiphenyl trichloroethane (DDT), but epidemiologic investigations of DDT and SAB are inconsistent. We undertook a pilot investigation of the hypothesized association of DDT with SAB. METHODS: Participants in this case-control study were selected from a longitudinal study of reproductive effects of rotating shifts among female Chinese textile workers who were married, ages 22-34, nulliparous without history of SAB or infertility, and planning pregnancy. From 412 pregnancies, 42 of which ended in SAB, 15 SAB cases and 15 full-term controls were randomly selected and phlebotomized. Serum was analyzed for p,p ' -DDT, o,p ' -DDT, their metabolites (DDE and DDD), and other organochlorines including polychlorinated biphenyls. RESULTS: Cases and controls were nonsmokers and did not differ in age (mean 25 years), body mass index (BMI), passive smoke exposure, or workplace exposures. Cases had significantly (p < 0.05) higher serum levels of p,p ' -DDE (22 vs. 12 ng/g) and o,p ' -DDE (0.09 vs. 0.05 ng/g) than controls. After adjustment for age and BMI, each ng/g serum increase in p,p ' -DDE was associated with a 1.13 (Cl, 1.02-1.26) increased odds of SAB. With adjustment of serum DDE levels for excretion via breastfeeding, DDE-associated increased odds of SAB remained significant with up to 7% declines in maternal serum DDE levels for each month of breastfeeding. CONCLUSIONS: A potential increased risk of SAB is associated with maternal serum DDE levels.

The precise mechanisms that regulate increases in airway smooth muscle (ASM) mass in asthma are unknown. This study determined whether class IA phosphatidylinositol 3-kinase (PI3K) is sufficient to stimulate DNA synthesis and characterized the PI3K isoforms expressed in human ASM cells. ASM cells express class IA, II, and III PI3K but not class IB. Because thrombin induces ASM cell proliferation, we investigated whether thrombin can stimulate class IA PI3K. Transient transfection of ASM cells with hemagglutinin-tagged p85 PI3K followed by immunostaining revealed that in quiescent cells, p85 was expressed diffusely in the cytoplasm and after stimulation with thrombin p85 translocated to the cell membrane. Microinjection of ASM cells with a dominant negative class IA PI3K inhibited thrombin-induced DNA synthesis by 30% and epidermal growth factor (EGF)- or serum-induced DNA synthesis by 13 and 28%, respectively (P < 0.05 by χ2 analysis). In parallel experiments, transfection or microinjection of cells with constitutively active PI3K markedly increased DNA synthesis in transfected cells 10.5-fold and in microinjected cells 12.7-fold (P < 0.05 by χ2 analysis) compared with cells transfected or microinjected with control plasmid. Interestingly, constitutively active PI3K augmented EGF-induced DNA synthesis but had little effect on that induced by serum or thrombin in ASM cells. Collectively, these data suggest that class IA PI3K is activated by thrombin and is sufficient to induce ASM cell growth.

View description>>

The deformation behavior of as-grown and ion-beam-modified wurtzite GaN films is studied by nanoindentation with a spherical indenter. Atomic force microscopy (AFM) and cathodoluminescence are used to characterize the deformation mode. No systematic dependence of the mechanical properties on the film thickness (at least for thicknesses from 1.8 to 4 μm) as well as on doping type is observed. Results strongly suggest that (i) slips is the major contributor to the plastic deformation of crystalline GaN and (ii) slip nucleation (rather than a phase transformation) is responsible for "pop-in" events observed during loading. Indentation with an ∼ 4.2 μm radius spherical indenter at maximum loads up to 900 mN does not produce any cracking visible by AFM in crystalline GaN. Instead, under such loads, indentation results in a pronounced elevation of the material around the impression. Implantation disorder dramatically changes the deformation behavior of GaN. In particular, implantation-produced defects in crystalline GaN suppress (i) "pop-in" events during loading, (ii) slip bands observed by AFM, and (iii) the plastic component of deformation. GaN amorphized by ion bombardment exhibits plastic flow even for very low loads. The values of hardness and elastic modulus of amorphous GaN are dramatically reduced compared to those of as-grown GaN. © 2001 Materials Research Society.

Lattice rules are quasi-Monte Carlo methods for numerical multiple integration that are based on the selection of an s-dimensional integration lattice. The abscissa set is the intersection of the integration lattice with the unit hypercube. It is well-known that the abscissa set of a lattice rule can be generated by a number of fixed rational vectors. In general, different sets of generators produce different integration lattices and rules, and a given rule has many different generator sets. The rank of the rule is the minimum number of generators required to span the abscissa set. A lattice rule is usually specified by a generator set, and the quality of the rule varies with the choice of generator set. This paper describes a new method for the construction of generator sets for higher-rank rules that is based on techniques arising from the theory of simultaneous Diophantine approximation. The method extends techniques currently applied in the rank 1 case.

The adverse effect of low intensity, small band UV-B irradiation (λ=305±5 nm, I=300 mW m-2) on PS II has been studied by comparative measurements of laser flash-induced changes of the absorption at 325 nm, ΔA325(t), as an indicator of redox changes in QA, and of the relative fluorescence quantum yield, F(t)/Fo, in PS II membrane fragments. The properties of untreated control were compared with those of samples where the oxygen evolution rate under illumination with continuous saturating light was inhibited by up to 95%. The following results were obtained: a) the detectable initial amplitude (at a time resolution of 30 μs) of the 325 nm absorption changes, ΔA325, remained virtually invariant whereas the relaxation kinetics exhibit significant changes, b) the 300 μs kinetics of ΔA325 dominating the relaxation in UV-B treated samples was largely replaced by a 1.3 ms kinetics after addition of MnCl2, c) the extent of the flash induced rise of the relative fluorescence quantum yield was severely diminished in UV-B treated PS II membrane fragments but the relaxation kinetics remain virtually unaffected. Based on these results the water oxidizing complex (WOC) is inferred to be the primary target of UV-B impairment of PS II while the formation of the 'stable' radical pair P680+•QA-• is almost invariant to this UV-B treatment.

View description>>

Many oceanographic studies on the eastern seaboard of Australia have utilised as a benchmark, the long-term records from the Commonwealth Scientific and Industrial Research Organisation 50 and 100m sites off Port Hacking, near Sydney. This 57-year physico-chemical record is tested for bias (eg. 'fair weather' sampling bias), to assess the degree to which temporal variability is captured and to assess potential for spatial extrapolation. The data is found to be well correlated for all-weather conditions, and indicates there is an alongshore, cooling trend in the region that may be related to shelf break divergence. We explore this record for long-term patterns and their association with the known large-scale phenomenon, El Niño. Discrete short-term biological (phytoplankton) and physico-chemical studies, interpreted in the context of long-term background climatic variability indicate anomalous conditions that appear to be related to El Niño. Warmer conditions associated with reduced nutrient levels were experienced during a recent study undertaken by Ajani et al (this volume) during the strong El Niño of 1997/98. These anomalies are similar to measured differences between normal and El Niño years experienced at the study site over the 57-year record. A comparison of this anomalous year to previous phytoplankton studies done at the Port Hacking 100m station suggests the anomalous physico-chemical conditions corresponded with atypical phytoplankton blooms of Thalassiosira spp. and Noctiluca scintillons. These results indicate that a better understanding of climatic variance is required when attempting to define impacts (such as anthropogenic inputs) on a coastal system from short-term studies. This approach enables a more thorough interpretation of current and historical data sets especially in cases where appropriate reference/control (putatively unimpacted) sites were unavailable or not monitored.

View description>>

Warm nutrient-poor water, associated with the 1997/98 El Niño, dominated conditions along Australia's east coast for the majority of 1997. Towards the end of the El Niño event, anomalously cool nutrient-rich water prevailed in coastal waters in response to a strong upwelling associated with enhanced dynamics from the East Australian Current and upwelling favourable winds. The upwelling was consistent with anomalously cool conditions observed during the demise of previous El Niño periods at the study location. Phytoplankton responses included blooms of the small centric diatom Thalassiosira spp. and the large heterotrophic dinoflagellate Noctiluca scintillons. Repetitive physico-chemical and biological sampling along cross-shelf transect lines combined with a 300km alongshore array of thermistor moorings, and ground-truthed SeaWiFS observations, captured this event. Enhanced East Australian Current activity to the north, and upwelling favourable winds across the study region, promoted cool nutrient-rich slope-waters to be uplifted onto the continental shelf. Thermistor records suggest this event swamped the entire study region in early January 1998 and remained until early February 1998. Crossspectral phase analysis of the records confirms these spatial and temporal observations. Nutrient levels peaked at the 99%ile value of records from 57 years monitoring at the study location. Slope-waters uplifted to the euphotic zone, enhanced populations of both primary and secondary phytoplankton bloom species, which extended to mid February 1998. SeaWiFS imagery indicates the formation of a cyclonic back-eddy on the inshore edge of the East Australian Current, and in the lee of a major topographic protrusion. This back-eddy isolates slope-waters and incubates phytoplankton, leaking alongshore with the general southward streamflow. Assessments of the reproductive status and feeding activity of Noctiluca indicate a maturing population with increasing southerly extent, thereb...

Recent studies have suggested that seed size and plant abundance in communities are associated. However, inconsistent patterns have emerged from these studies, with varying mechanisms proposed to explain emergent relationships. We employ a theoretical framework, based on key theory lineages of vegetation dynamics and species coexistence, to examine relationships between species abundance and seed size. From these theory lineages, we identified four models and their predictions: the Seed size/number trade-off model (SSNTM), the Succession model (SM), the Spatial competition model (SCM), and the Lottery model (LM). We then explored empirical evidence from ten diverse plant communities for seed size and abundance patterns, and related these patterns to model predictions. The SSNTM predicts a negative correlation between seed size and abundance.

The Al-Au-Cu system and its associated ternary alloys and intermetallic compounds is surprisingly poorly known, and the authors could find no phase diagram for it in the literature. This article addresses this omission by presenting an isothermal section at 500 °C, derived with the aid of X-ray diffraction (XRD), energy-dispersive spectroscopy (EDS), metallography, and hardness measurements. The samples studied had generally received an anneal of 2 hours at 500 °C, primarily in order to complete any transformations that occurred during solidification and cooling of the castings. The possibility of further changes on protracted annealing at 500 °C is not ruled out, and the diagram presented is, therefore, applicable only to material prepared by thermal processing of an industrial nature. The presence of a ternary ? phase with a nominal stoichiometry of AlAu2-x Cu1-x (0?x?1) was confirmed, and its phase field at 500 °C was determined. A number of the binary intermetallic phases were found to exhibit some solid solubility of the ternary element. In particular, the ?-Al4Cu9 phase extends deep into the ternary and, in the vicinity of the commercially interesting 18-carat line, appears to exist in a ternary ordered form, designated here as ? 2

Given an elevated prevalence of respiratory disease and density of pollution sources, residents of Roxbury, Massachusetts, have been interested in better understanding their exposures to air pollution. To determine whether local transportation sources contribute significantly to exposures, we conducted a community-based pilot investigation to measure concentrations of fine particulate matter (particulate matter < 2.5 m; PM2.5) and particle-bound polycyclic aromatic hydrocarbons (PAHs) in Roxbury in the summer of 1999. Community members carried portable monitors on the streets in a 1-mile radius around a large bus terminal to create a geographic information system (GIS) map of concentrations and gathered data on site characteristics that could predict ambient concentrations. Both PM2.5, and PAH concentrations were greater during morning rush hours and on weekdays. In linear mixed-effects regressions controlling for temporal autocorrelation, PAH concentrations were significantly higher with closer proximity to the hus terminal (p < 0.05), and both pollutants were elevated, but not statistically significantly so, on bus routes. Regressions on a subset of measurements for which detailed site characteristics were gathered showed higher concentrations of both pollutants on roads reported to have heavy bus traffic. Although a more comprehensive monitoring protocol would be needed to develop robust predictive functions for air pollution, our study demonstrates that pollution patterns in an urban area can be characterized with limited monitoring equipment and that university-community partnerships can yield relevant exposure information.

Hyper-Rayleigh scattering was used to determine the first hyperpolarisability, , the data showing that (a) is dependent on the metal in the acceptor fragment, (b) increased when Cl or Br was replaced by I and (c) increased when the number of methyl groups on the cyclopentadienyl rings increased. The -values for comparable complexes containing {Mo(NO)(TpMe,Me)Cl} and {W(CO)5} moieties were similar. Chemical oxidation of the ferrocenyl or chemical reduction of the molybdenum nitrosyl acceptor fragments in selected complexes caused a reduction of between 25% and 100% in the NLO response.

This study investigated the evidential value of specific methods of analysis for packaging tapes and clear adhesive tapes available in Australia. Fifty-eight adhesive tapes were analyzed using a wide range of optical, physical, and chemical techniques. The results were collated for the purpose of creating an Australian database of adhesive tapes, which would be of assistance in criminal investigation. Each technique was evaluated for its discriminating power, both for comparative purposes and for the identification of adhesive tapes by comparing unknown samples with the database. The combined discriminating power of the techniques applied is very high. It is possible to individually identify the source of an unknown adhesive tape sample in many instances by searching the database. It is also possible to form an opinion on the significance of a failure-to-discriminate result in comparative casework. Further work is still needed to expand and update the database, as well as compiling data on the relative market share of various products.

Sea mice (Aphroditidae, Polychaeta) are furry-looking marine worms that forage on, or in, the sea-bed. They are distinguished by an amazing iridescence along the lower sides of the body, associated with both hairs and spines known as chaetae. We show by electron microscopic and optical analysis that the iridescence of spines is caused by a highly regular, sub-micron scale structure resembling that being developed for photonic crystals, and that in fact the sea mouse exploits a partial photonic band gap to achieve its remarkable coloration effects.

To prepare hydroxyapatite (HA, or HAp)-stainless steel 316L fibre composites with up to 30 vol% 316L fibres (sim1 mm long and 50 mgrm in diameter), slip casting assisted by vibration (frequency: sim55 Hz; amplitude: sim5 mm) was carried out, followed by both cold isostatic pressing (CIPing) and hot isostatic pressing (HIPing). With the addition of around 0.5 wt% sodium carboxymethylcellulose (Na-cmc), solids loadings up to 44 vol% were obtained in calcined HA powder-derived slips, which were castable only under the vibration. The slips were concentrated and viscous so that the preferential sedimentation of the dense and large 316L fibres could be avoided. Subsequent CIPing was able to increase the relative density of the cast and dried green compacts from 46% after casting to 60% after CIPing. With the dense and uniform green compacts of the HA-316L mixtures, final HIPing at 950 °C resulted in HA-316L fibre composites of 99% relative density. The HA-316L fibre composites had improved fracture toughness of 3.6 ± 0.3 MPa.m0.5, due to the bridging effect of the ductile 316L fibres. However, the mechanical strength of the composites was limited by the presence of residual thermal stresses and circumferential microcracks. The HA-316L fibre composites were biocompatible and exhibited favourable bone-bonding characteristics.

A one-year field study was carried out in 45 households in Cairns, North Queensland to evaluate the efficacy of three topical or systemic treatment programs in controlling cat flea (Ctenocephalides felis) infestations within the residence and on dogs and cats. Homes were randomly assigned to one of three treatments. In the first group of homes, lufenuron was administered orally to all household pets according to label recommendations for the study duration, and nitenpyram was administered orally once per week for the first 6 weeks. After 6 weeks, all pets in the household received a single dose of nitenpyram if fleas were observed on any animal. Treatments in the second group of homes were identical to those for the first group except that all pets in the household received two doses of nitenpyram per week. In the final group, imidacloprid was applied topically to all household pets once every 4 weeks for the duration of the study, and no other flea-control measures were applied. Flea populations on the pets of all treatment groups were assessed; environmental flea numbers were assessed only for Groups 1 and 3. The combination of lufenuron and nitenpyram provided superior control of flea populations on the animals and in the environment compared with using imidacloprid alone.

View description>>

A new, mechanistic approach for design and analysis of subsurface flow (SSF) constructed wetlands is presented. The model is based on the assumption that the biological processes in wetlands, like other biological systems, exhibit Monod kinetics. A Monod approach fits well with observed wetland performance. It predicts first-order behaviour at low concentrations, that is, pollutant removal rates which increase with increasing pollutant concentration; and zero-order or saturated behaviour at high pollutant concentrations, that is, a maximum pollutant removal rate. A kinetic analysis of subsurface flow constructed wetlands exhibiting Monod kinetics reveals that loading rate, as well as the zero-order degradation rate constant, are essential parameters for efficient wetlands design for the removal of organic carbon. In particular, Monod kinetics enables the identification of an absolute maximum removal rate which is necessary to prevent undersizing in design. This is significant because it represents a theoretical upper bound on loading rate for wetlands design. The analysis is applied to wetlands data collected in North America by the US EPA in order to extract design criteria for BOD removal. It reveals that maximum loadings for SSF wetlands are at least 80kgha-1d-1 for BOD. In addition, a new dimensionless performance efficiency parameter, Omega, is presented as a more effective means of comparing wetland performance.

Vertical profiles of Microcystis aeruginosa and other phytoplankton were measured on several occasions within the main channel and an embayment of a freshwater tidal river. The cyanobacteria M. aeruginosa and Anabaena circinalis were able to migrate to surface waters within the embayment but not within the main channel. Using a quantitative estimate of primary productivity (over a 24 hour period), the potential benefits through disentrainment by buoyancy were determined for M. aeruginosa within the embayment and compared to the main channel. The population within the embayment had a daily integral of photosynthesis of 603.13 mmol of O(2)m(-2), nine times greater than the evenly distributed main channel population with a daily integral of 62.08 mmol of O(2)m(-2). It is likely that embayments along the tidally mixed reaches of the Hawkesbury River may be areas where M. aeruginosa can disentrain through buoyancy and enhance primary productivity rates.

View description>>

The Hawkesbury River at Sackville, New South Wales, Australia is fresh and vigorously mixed by tidal movement. The location has frequent blooms of Microcystis aeruginosa, which have been recorded occurring throughout the year, including winter temperatures as low as 13 °C. Nutrient enrichment tests were performed in-situ on the natural phytoplankton population in 1997 and 1998 while Microcystis aeruginosa dominated (covering both summer and winter periods). These experiments compared population changes under the ambient nutrient regime with those after additions of ortho-phosphate, nitrate, ammonia and various combinations of these nutrients. Under ambient conditions, the Microcystis population was able to grow significantly (P < 0.05) while most non-cyanobacterial phytoplankton did not. Nutrient additions induced a variety of nutrient limitation responses that often varied between genera of major groups i.e. in the Chlorophyceae (Actinastrum sp. responded to phosphorus while Psephonema sp. responded to nitrogen). The possibility that shifts in population dominance from Chlorophyceae to the Cyanobacteria (M. aeruginosa) at Sackville are in response to competition for limiting nutrients is discussed

View description>>

An error and sensitivity analysis was conducted to investigate the capabilities of the atmospheric resistant vegetation indices (VIs) for minimizing ''residual aerosol'' effects. The residual aerosol effects result from the assumptions and characteristics of the dark target (DT) approach used to estimate aerosol optical properties in the atmospheric correction scheme (referred to as the dark target-based atmospheric correction, DTAC). The performances of two atmospheric resistant VIs, the atmospherically resistant vegetation index (ARVI) and enhanced vegetation index (EVI), were evaluated and compared with the normalized difference vegetation index (NDVI) and soil adjusted vegetation index (SAVI). The atmospheric resistant VIs successfully minimized the residual aerosol effects, resulting in a 60% reduction of the errors from the NDVI and SAVI when a proper aerosol model was used for the estimation and correction of aerosol effects. The reductions were greater for thicker aerosol atmosphere (larger aerosol optical thickness, AOT). The atmospheric resistant VIs, however, resulted in having larger bias errors than the NDVI and SAVI when an improper aerosol model was used. The application of atmospheric resistant VIs to the DTAC-derived surface reflectances is exactly what is being carried out by the Moderate Resolution Imaging Spectroradiometer (MODIS) VI algorithm. These results raise several issues for the effective, operational use of the DTAC algorithm and atmospheric resistant VIs, which are addressed in this paper.

The present study investigated nighttime fears in normal school children aged 4 to 12 yr (N=176). Children and their parents were interviewed about the frequency, content, origins, coping behaviors and severity of children's nighttime fears. Results showed that 73.3% of the children reported nighttime fears, indicating that these fears are quite prevalent. Inspection of the developmental course of nighttime fears revealed that these fears are common among 4- to 6-year-olds, become even more frequent in 7- to 9-year-olds and then remain relatively stable in 10- to 12-year-olds. Inspection of the origins of nighttime fears revealed that most of the children (i.e., almost 80%) attributed their fear to negative information; conditioning and modeling were endorsed less frequently (25.6% and 13.2%, respectively). A substantial percentage of the children (24.0%) indicated that learning experiences had not played a role in the acquisition of their nighttime fears. Children reported a variety of coping strategies in order to deal with their nighttime fears and generally rated these strategies as helpful in reducing anxiety. Furthermore, children's nighttime fears were associated with moderate levels of anxiety. Moreover, in about 10% of the children, nighttime fears were related to one or more DSM-III-R anxiety disorders. Finally, parental reports of children's nighttime fears substantially deviated from children's reports. Most importantly, parents provided a marked underestimation of the frequency of nighttime fears, at least as reported by their children. Copyright (C) 2000 Elsevier Science Ltd.

The performance of current mesoscale numerical models is evaluated in a case of model intercomparison project (COMPARE III). Explosive development of Typhoon Flo (9019) occurred in the case in September 1990 during the cooperative three field experiments, ESCAP/WMO-led SPECTRUM, US-led TCM-90, and former USSR-led TYPHOON-90 in the western North Pacific. Sensitivity to initial fields as well as impact of enhanced horizontal resolution are examined in the model intercomparison. Both track and intensity predictions are very sensitive to the choice of initial fields prepared with different data assimilation systems and the use of a particular synthetic tropical cyclone vortex. Horizontal resolution enhanced from 50km through 20km down to a 10km grid has a large impact on intensity prediction. This is presumably due to a better presentation of inner structure with higher resolution. There is little impact on track prediction in this target period when the typhoon was in its before-recurvature stage. While most models show large biases in underestimating central pressure deepening, some of the participating models with a particular initial field succeed in reproducing qualitatively the time evolution of central pressure, including slow deepening in the first half and rapid deepening in the second half of the simulation period of 72 hours. However, differences leading to different intensity predictions among models have yet to be identified. Intercomparison of the simulation results shows that wind field has a close relationship with precipitation distribution. This suggests that better prediction of precipitation distribution is crucial for better prediction of wind field, and vice versa. Through the COMPARE III experiments, it has become clear that precise simulation of tropical cyclone structure, especially in the inner-core region, is very important for accurate intensity prediction. Consideration, therefore, should be given to this point, when improvements in resol...

This study tested the relationship between three, commonly-used vegetation indices (VIs), percent vegetation cover (% cover) and leaf area index (LAI) over a complex riparian landscape in the Colorado River delta, Mexico. Our objective was to correlate vegetation and soil features with VIs using low-level aerial photography, in preparation for scaling up to analysis of vegetation features using satellite imagery. We used a three-band digital imaging camera (Dycam) to collect data from an aircraft flying at 150 m. A series of 84 images (67×100 m) were analysed. Nine of these sites were ground-truthed; the species, % cover, and LAI were determined. Measured LAI (nine sites) from tree, shrub, and groundcover categories were used to determine a global (GLAI) value for 63 images. We conducted both VIs:% cover and VIs:GLAI regression analyses. The normalized difference vegetation index (NDVI) was the VI that best predicted % cover (r2=0·837), but the soil adjusted vegetation index (SAVI) and enhanced vegetation index (EVI) gave nearly equal results (r2=0·807 and 0·796, respectively). Normalized difference vegetation index, SAVI and EVI were less useful in predicting GLAI (r2=0·73, 0·65, 0·64, respectively).

A cross section of the discarded plinth from the Australian Museum in College Street, Sydney was analyzed to determine differences in the physical and chemical properties of Maroubra sandstone after a century of natural exposure. Thin section petrography shows the sandstone contains 65 percent quartz, 14 percent each of clay and pores with minor amounts of siderite (3 percent) and secondary quartz (1.2 percent). Preliminary compressive strength tests indicate the Maroubra sandstone cross-section ranged from 28.63 MPa to 42.84MPa in dry conditions, while it lost approximately half its strength in wet conditions. X-ray diffraction and infrared analysis confirm the clay that binds Maroubra sandstone is predominately kaolinite with minor amounts of illite. Subtle differences in kaolinite detected by infrared spectroscopy may be due to partial iron substitution of aluminium in the clay.

In this study, we explored relations among negative life events, negative attributional style, avoidant coping, and level of fear in 99 children who had survived residential fires. Overall, negative life events, negative attributional style, and avoidant coping were found to be predictive of levels of fear. However, the relation between negative life events and fear was moderated by mother's level of education such that this prediction was obtained only for those children whose mothers were low in education level. Age, ethnicity, and sex did not moderate these relations. In addition, negative attributional style and avoidant coping were related to levels of fear in those children whose mothers were high in educational levels but not those whose mothers were low in educational level. Results are discussed within a stress and coping framework.

In this paper, we examine the role of developmental theory in the assessment and treatment of child behaviour disorders, with special reference to the anxiety disorders. Following a brief review of the tenets of developmental psychology and developmental psychopathology, we illustrate the role of developmental theory in clinical research and practice. We suggest that developmental theory guides us in the selection and use of developmentally sensitive assessment strategies. Moreover, we indicate that use of developmental theory assists us in the treatment of children and adolescents by helping us determine when a behaviour problem is significant and when to initiate treatment, how to determine the goals of treatment and to select targets for treatment outcome, which treatment strategies to select for intervention, and how to determine the context of intervention. We conclude that the importance of developmental theory is axiomatic when working with children and adolescents. Still, considerable more work is needed before we can conclude that we have fully integrated developmental theory into our ongoing clinical research and practice with children.

Asthma is characterized by inflammation, hyper-responsiveness, and remodeling of the airway. Human mast cells (HMCs) play a central role in all of these changes by releasing mediators that cause exaggerated bronchoconstriction, induce human airway smooth muscle (HASM) cell proliferation, and recruit and activate inflammatory cells. Moreover, the number of HMCs present on asthmatic HASM is increased compared with that on nonasthmatic HASM. HASM cells also have the potential to actively participate in the inflammatory process by synthesizing cytokines and chemokines and expressing surface molecules, which have the capacity to perpetuate the inflammatory mechanisms present in asthma. This review specifically examines how the mediators of HMCs have the capacity to modulate many functions of HASM; how the synthetic function of HASM, particularly through the release and expression of stem cell factor, has the potential to influence HMC number and activation in an extraordinarily potent and proinflammatory manner; and how these interactions between HMCs and HASM have potential consequences for airway structure and inflammation relevant to the disease process of asthma.

View description>>

The estimation of the incidence of tumours in an animal carcinogenicity study is complicated by the occult nature of the tumours involved (i.e. tumours are not observable before an animal's death). Also, the lethality of tumours is generally unknown, making the tumour incidence function non-identifiable without interim sacrifices, cause-of-death data or modelling assumptions. Although Kaplan-Meier curves for overall survival are typically displayed, obtaining analogous plots for tumour incidence generally requires fairly elaborate model fitting. We present a case-study of tetrafluoroethylene to illustrate a simple method for estimating the incidence of tumours as a function of more easily estimable components. One of the components, tumour prevalence, is modelled by using a generalized additive model, which leads to estimates that are more flexible than those derived under the usual parametric models. A multiplicative assumption for tumour lethality allows for the incorporation of concomitant information, such as the size of tumours. Our approach requires only terminal sacrifice data although additional sacrifice data are easily accommodated. Simulations are used to illustrate the estimator proposed and to evaluate its properties. The method also yields a simple summary measure of tumour lethality, which can be helpful in interpreting the results of a study.

Interferon-γ is a pivotal cytokine in the protective response to tuberculosis. In its absence rampant bacterial growth results in tissue destruction and death. While macrophage activation is key, this pleiotropic cytokine has other secondary but significant roles. To investigate these roles, both intravenous and aerosol infection of the IFN-γ gene disrupted (GKO) mouse was performed. For the first time we describe the very similar growth of bacteria, during the initial phase of infection, between control and GKO mice. During this initial phase, however, very different histopathologic consequences between control and GKO mice were observed. Key observations included an early increased accumulation of granulocytes and a much more rapid and pronounced interstitial pneumonia in the GKO mice. As infection developed, GKO mice mounted an antigen-specific response; however, lymphocyte activation was much more rapid in these mice. Of interest is the fact that this increased rapidity occurred prior to significant differences in bacterial number. Taken together these data support a role for IFN-γ in limiting both initial cellular recruitment and acquired lymphocytic responses to mycobacterial infection. This role may be key in surviving the kind of chronic stimulatory disease caused by Mycobacterium tuberculosis. © 2001 Academic Press.

We consider formulations for the Helmholtz operator for periodic media containing high contrast inclusions in the limit when the wavelength outside the inclusions tends to infinity. Applications are to problems of electromagnetism. The main focus is on the analysis of the effect of noncommuting limits, an effect which indicates that linear boundary value problems of electromagnetism give formally different results for the long wavelength limits in cases where highly conducting inclusions have refractive indices of different orders of magnitude. Specifically, the effective moduli of the homogenized material will depend on the path used to approach the origin in the coordinate space {wave number, (normalized refractive index of the inclusions)-1}. This mathematical observation gives a physical subtlety which is studied in this paper. The dispersion relation for the lowest frequency (or acoustic mode) is investigated, as are the conditions for existence of an acoustic mode. Cases of both nondispersive and dispersive inclusions are considered.

View description>>

We investigated the effects of major sewage and estuarine discharges on nutrient distributions in the central New South Wales (NSW) coastal waters. The hinterland of the study region includes the sewerage and rainwater catchments of major population centres of Newcastle, Sydney and Wollongong. New South Wales discharges the majority of its treated sewage to the ocean, with about 80% from just three deepwater outfalls off Sydney. These discharges were found to be the principal, continuous, anthropogenic source of nutrients to NSW coastal waters. The deepwater outfalls delivered most of their nitrogen as ammonia and were responsible for nutrient (NH4-N and PO 4-P) enrichment within usually submerged effluent plumes. Direct observations and modelling indicate that after initial dilution, effluent plumes typically occupy ~30m of the water column (60-80m). Rapid initial dilution was observed with subsequent gradual far field dispersion typically broadening the effluent field tol-2 kilometres by about 10 kilometres downstream. Flows generally follow isobaths, predominantly to the south. Vertical and seasonal distributions of sewage derived nutrients, were estimated from a 6 year record of initial dilution modelling and effluent data. Comparisons were made with ambient nutrient distributions derived from long term monitoring prior to the commissioning of the outfalls (1990), at the CSIRO Port Hacking Station (5 to 10 kilometres south of the deepwater outfalls). The pycnocline seasonally limited the vertical extent of sewage plumes emitted from the deepwater outfalls. Upwelling/uplifting processes were associated with stratified conditions during spring and summer. Therefore, density stratification was a critical factor in determining the vertical movement of oceanic and sewage derived nutrients into the euphotic zone. Despite clear nutrient enrichment due to sewage discharges, no new evidence has been presented to contradict previous findings that algal blooms are princ...

Hypochlorite is a major oxidant generated when neutrophils and macrophages are activated at inflammatory sites, such as in atherosclerotic lesions. Murine S100A8 (A8) is a major cytoplasmic protein in neutrophils and is secreted by macrophages in response to inflammatory stimuli. After incubation with reagent HOCl for 10 min, ~85% of A8 was converted to 4 oxidation products, with electrospay ionization mass spectrometry masses of m/z 10354, 10388, 10354 ± 1, and 20707 ± 3. All were resistant to reduction by dithiothreitol. Initial formation of a reactive Cys sulfenic acid intermediate was demonstrated by the rapid conjugation of 5,5-dimethyl-1,3-cyclohexanedione (dimedone) to HOCl-treated A8 to form stable adducts. Matrix-assisted laser desorption-reflectron time of flight peptide mass fingerprinting of isolated oxidation products confirmed the mass additions observed in the full-length proteins. Both Met36/73 were converted to Met36/73 sulfoxides. An additional product with an unusual mass addition of m/z 14 (±0.2) was identified and corresponded to the addition of oxygen to Cys41, conjugation to various epsilon -amines of Lys6, Lys34/35, or Lys87 with loss of dihydrogen and formation of stable intra- or inter-molecular sulfinamide cross-links. Specific fragmentations identified in matrix-assisted laser desorption-post source decay spectra and low energy collisional-induced dissociation tandem mass spectroscopy spectra of sulfinamide-containing digest peptides confirmed Lys34/35 to Cys41 sulfinamide bonds. HOCl oxidation of mutants lacking Cys41 (Ala41S100A8) or specific Lys residues (e.g. Lys34/35, Ala34/35S100A8) did not form sulfinamide cross-links. HOCl generated by myeloperoxidase and H2O2 and by phorbol 12-myristate 13-acetate-activated neutrophils also formed these products.

Capacitance and other properties of large metal clusters proposed for use as nanoelectrodes in complex molecular-electronic devices, or as cores of the monolayer-passivated nanoparticles studied by Murray (J. Phys. Chem. B 1999, 103, 9996), are discussed using atomistic formalisms based on classical electrostatics as well as INDO electronic structure theory. Using classical electrostatics, both finite-size and atomicity effects are found to be important for properties such as the surface charge distribution but unimportant for other properties such as the electric field profile between electrodes. The INDO and classical atomistic charge distributions are found to be strikingly different, with both departing from textbook expectations based on theorems of classical continuum electrostatics such as Gauss' law. For linear chains of metallic atoms, ab initio full configuration interaction as well as density-functional (DFT) calculations validate the INDO/S picture in which both positively and negatively charged atoms appear within a chain of net positive charge, contrary to the classical treatment that permits only distribution of the net charge. Examination of the form of the INDO/S Hamiltonian reveals that a key aspect of the failure of classical atomistic electrostatics arises from its treatment of self-energy (the energy required to store a finite charge in the finite atomic volume). Exchange operators present in the quantum approaches halve the classical self-energy contributions, facilitating charging. Even the requirement that atomic charges be distributed across the width of a surface atomic plane is found to significantly modify the classical self-energy and hence induce large short-range deviations from standard capacitance relationships. For large clusters, the INDO/S results are shown to depict qualitatively reasonable properties by comparison with published DFT calculations. INDO/S may prove an efficient computational scheme for the study of a wide range...

Phosphate uptake rates were measured in Synechococcus R-2 incubated in artificial secondary- and tertiary-treated sewage. Phosphate uptake was measured using chemical assay and 32P incorporation. Intracellular pH was measured using accumulation of 14C-labelled weak acids and bases and membrane potentials using 86Rb+/valinomycin. Synechococcus cells are capable of very rapid, opportunistic uptake of phosphate (10-30 nmol m-2s-1) even though net uptake by growing cultures was ≤ 0.5 nmol m-2 s-1. Km and Vmax in the light were not significantly different at pH0 7.5 and 10. The mean Km values were 1.91 ± 0.41 mmol m-3 and 0.304 ± 0.055 mmol m-3 for P-sufficient (secondary-treated sewage) and P-deficient (tertiary-treated sewage) cells, respectively. The transport systems probably recognize both H2PO4- and HPO42-. Intracellular inorganic phosphate is +28 to +56 kJ mol-1 from electrochemical equilibrium. In P-sufficient cells uptake is very slow in the dark (c. 0.1 nmol m-2 s-1) but phosphate-starved cells can opportunistically take up P about 100 times faster. Two separate ATP-driven phosphate uptake mechanisms (1 PO4 in per ATP) appear to be responsible for phosphate uptake by the cells. They have different Km values, different light/dark responses and electrical behaviour.

Although the essential role of tumor necrosis factor (TNF) in the control of intracellular bacterial infection is well established, it is uncertain whether the related cytokines lymphotoxin-α (LTα3) and lymphotoxin-β (LTβ) have independent roles in this process. Using C57Bl/6 mice in which the genes for these cytokines have been disrupted, we have examined the relative contribution of secreted LTα3 and membrane-bound LTβ in the host response to aerosol Mycobacterium tuberculosis infection. To overcome the lack of peripheral lymph nodes in LTα-/- and LTβ-/- mice, bone marrow chimeric mice were constructed. LTα-/- chimeras, which lack both secreted LTα3 and membrane-bound LTβ (LTα1β2 and LTα2β1), were highly susceptible and succumbed 5 wk after infection. LTβ-/- chimeras, which lack only the membrane-bound LTβ, controlled the infection in a comparable manner to wild-type (WT) chimeric mice. T cell responses to mycobacterial antigens and macrophage responses in LTα-/- chimeras were equivalent to those of WT chimeras, but in LTα-/- chimeras, granuloma formation was abnormal. LTα-/- chimeras recruited normal numbers of T cells into their lungs, but the lymphocytes were restricted to perivascular and peribronchial areas and were not colocated with macrophages in granulomas. Therefore, LTα3 is essential for the control of pulmonary tuberculosis, and its critical role lies not in the activation of T cells and macrophages per se but in the local organization of the granulomatous response.

A total of 776 pairs of shoes collected from random members of the public in south-eastern Australia were examined for the presence of glass fragments. From the samples collected a total of 110 fragments were recovered from 57 pairs of shoes (7.3% of the pairs examined). This study shows that the prevalence of glass fragments in footwear is dependent upon the area of the shoe from which the fragments were recovered. A much higher percentage of shoes were found to have fragments embedded in the sole (5.9%) than in the upper area of the shoe (1.9%). These shoes were also more likely to have multiple fragments from multiple sources of glass. Only a very small percentage of shoes contained fragments in both the upper and the sole (0.3%). These ®ndings and their signi®cance for the interpretation of glass evidence involving footwear are discussed in this study.

We have measured the binding energy of the Be1s core-level in metallic beryllium using an electron-impact ionisation technique--electron momentum spectroscopy (EMS). The value we obtain, 111.7+/-0.1 eV, is in good agreement with previous results. We have also determined the chemical shift of the core level in an oxygen environment to be 2.68+/-0.06 eV. Using the same technique, we have followed the evolution of the core-level peak as Be undergoes surface reaction induced by background gases present in the vacuum (mainly water vapour and nitrogen). The core-level peak intensities as a function of time clearly show that reaction of the Be surface progresses in two distinct steps. The initial relatively rapid stage progresses up to a coverage of around 18 L of H2O and N2 after which the onset of a slower reaction process is observed. These results demonstrate the ability of EMS to provide time-resolved electronic structure measurements as a solid undergoes chemical modification.

Cigarette smoking and poor glycemic control are risk factors for diabetic nephropathy in type 1 diabetes. However, the specifics of the relation of these risk factors to the onset of this complication have not been elucidated. To investigate these issues, we followed for 4 years 943 Joslin Clinic patients aged 15-44 years with type I diabetes who had normoalbuminuria during the 2-year baseline period. Microalbuminuria developed in 109 of the 943 individuals, giving an incidence rate of 3.3/100 person-years. The risk of onset of microalbuminuria was predicted somewhat more precisely by the measurements during the 1st and 2nd years preceding onset than by all the measurements during the longer (4-year) interval, suggesting attenuation of the impact of past hyperglycemia over time. Point estimates of the incidence rate (per 100 person-years) according to quartiles of HbA(1c) during the 1st and 2nd years preceding the outcome were 1.3 in the 1st, 1.5 in the 2nd, 3.1 in the 3rd, and 6.9 in the 4th (P=1.3 x 10(-9)). Point estimates of the incidence rate (per 100 person-years) according to smoking status were 7.9 for current smokers, 1.8 for past smokers, and 2.2 for those who had never smoked (P=2.0 x 10(-7)). In a multiple logistic model, the independent effects of HbA(1c) level and cigarette smoking remained highly significant, but their magnitudes were reduced. Using the same covariates in a generalized additive model, we examined the shape of the relationship between HbA(1c) and onset of microalbuminuria and found significant nonlinearity in the logarithm of odds scale (P=0.04). The slope was steeper with HbA(1c) >8% than <8%. Furthermore, the change in the slope was magnified among current smokers. In conclusion, patients with type I diabetes who smoke and have an HbA(1c) > 8% have the highest risk of onset of microalbuminuria.

Production of thin ®lms of Titanium nitride (TiN) with N/Ti ratios as high as 1.3 has been achieved without destroying the metallic properties characteristic of stoichiometric TiN. The resultant change in mobile electron density shows that by depositing thin ®lms the onset of a rise in re¯ection can be pushed out almost into the near infra red. It then becomes possible to produce ®lms which transmit daylight neutrally at reasonably high levels, while still maintaining solar control in the NIR and a low emittance. Nitrogen ion assisted cathodic arc deposition has been used to achieve these results. Both the additional impacting and implanting nitrogen ions raise stoichiometry and help to reduce disorder so as to maintain good metallic character

The measurement of BRTF (Bi-directional rePectance and transmittance function) is described using a new instrument which is capable of supplying BRTF data and algorithms for use in computer simulations directly on di€use materials and indirectly on large samples and sub-systems. A high sensitivity and dynamic range is needed to achieve low minimum observable BRTF and the role of angular resolution are discussed with examples. Forward scattering with extended tails is found to dominate pigmented polycarbonate. Slatted blinds are discussed as examples of systems where azimuth is important.

The observed headflre rates of spread of two severe wildfires in heathlands near Sydney were compared with predictions made using a meteorological model to forecast wind speeds and a new simple empirical fire behaviour model that uses fuel height and wind speed at 2 m above ground to predict rate of spread. The predicted rates of spread, using both actual and predicted wind speeds, compared favourably with observed rates of spread averaged over 2 hours and 5.5 hours for the Bell Range and Royal National Park fires respectively.

The liver has been suggested as a suitable target organ for reversing type I diabetes by gene therapy. Whilst gene delivery systems to the hepatocyte have yet to be optimized in vivo, whether insulin-secreting hepatocytes are resistant to the autoimmune process that kills pancreatic -cells has never been addressed. One of the mechanisms by which -cells are killed in type I diabetes is by the release of the cytokines interleukin-1 (IL-1), tumour necrosis factor- (TNF-) and interferon- (IFN-) by immune cells. To test the effect of the cytokines on insulin-secreting hepatocytes in vitro we exposed the betacyte, also called the HEP G2ins/g cell which possesses cytokine receptors and can synthesize, store and secrete insulin in a regulated fashion to a glucose stimulus, to the above mentioned cytokines for 14 days. Viability of the HEP G2ins/g cells was similar to that of other liver cell lines/primary cells which were more resistant to the cytokines than the -cell line NIT-1. The cytokines had no adverse effect for the first six days on insulin secretion, content and mRNA levels of the HEP G2ins/g cells and insulin secretion in response to 1-h exposure to 20 mM glucose was enhanced 14-fold. Our results indicate that genetically engineered hepatocytes and primary liver cells are more resistant than pancreatic -cells to the adverse effects of cytokines offering hope that insulin secreting hepatocytes in vivo made by gene therapy are less likely to be destroyed by cytokines released during autoimmune destruction.

The degradation of poly(vinyl alcohol) was investigated using TG analysis and Fourier transforminfrared spectroscopy to determine the effect of atmosphere on the process of degradation. Inthe spectra, four vibrational modes were identified that characterised the major steps of thedegradation process. These were the O–H, C–H, C=O and C=C stretching modes. Themechanism observed for degradation in an inert atmosphere was in accordance with theaccepted mechanism of elimination followed by pyrolisation. Evidence of conjugatedpolyenes, however, was not observed. For the air atmosphere, oxidation in both steps of thedegradation process was observed.

A consequence of the generally low nutrient levels of Australian soils is that relationships between plants and their microbial symbionts (mycorrhizal fungi as well as nitrogen-fixing bacteria) have particular significance for conservation management, sustainable agriculture, and ecosystem rehabilitation. Shrubby legumes in the Fabaceae (e.g. Acacia, Daviesia, Dillwynia, Oxylobium, Hovea and Pultenaea) constitute a major group of plants that form nitrogen- fixing (N2-fixing) partnerships with root-nodule bacteria (species of rhizobia). These taxa are found throughout Australia, and are frequently a dominant part of undisturbed ecosystems, both in terms of abundance as well as overall biomass.

Films of polystyrene (PS) and poly(methyl methacrylate) (PMMA) blends of two different thicknesses have been examined by X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM). Blends with different compositions were spin-cast onto a mica substrate with chloroform as the mutual solvent. XPS measurements revealed surface enrichment of PMMA in all compositions. The thicker (66 nm) films exhibit a higher degree of PMMA surface enrichment than the thinner (17 nm) films. AFM imaging allows distinctions to be drawn between blends with differing compositions. The blend films with less than 50% PMMA bulk concentration generally exhibit pitted surfaces; the pit size varies with film thickness and bulk composition. When the PMMA bulk concentration is greater than 50%, the film surface changes to show island-like phase-separated structure. The surface segregation and morphology are explained in terms of solubilities of the two polymers in the solvent and dewetting of PMMA relative to PS. The phase domains on the film surface have also been resolved by frictional force microscopy (FFM) using hydrophilic tips bearing hydroxyl groups.

Detailed morphological study was conducted on the third-instar larvae of seven common carrion-breeding species of blowflies of the genus Calliphora Robineau-Desvoidy (Diptera : Calliphoridae) found in South Australia. The larval morphology of five species is revised: C. stygia (Fabricius), C. dubia (Macquart), C. augur (Fabricius), C. hilli hilli Patton and C. vicina Robineau-Desvoidy, while that of C. albifrontalis Malloch and C. maritima Norris is described for the first time. Examination of features neglected in descriptions by previous workers, particularly cuticular spinulation, has provided characters that make it possible to identify all species. An illustrated key is provided. Overall, substantial morphological distinctness exists only at the species-group level. Morphological differences at this level largely support species-group and subgeneric arrangements previously proposed for these taxa, as well as the separate status of C. vicina. However, the sister species within the C. stygia-and augur-groups are very difficult to separate, confirming the need for molecular identification in certain cases. © CSIRO 2001.

In this review, we examine the construct of self-esteem from a cross-cultural perspective in Chinese and Western children and adolescents. We also explore the role of childrearing practices in the development of self-esteem in these different cultures. In doing so, we first review the concepts of emic (i.e., variations in patterns of behavior within a given culture) and etic research (i.e., variations in common patterns of behavior or activities across cultures). Then, we invoke Berry's notions of "imposed-etic" and "derived-etic" approaches (J. Berry, 1989) in understanding crucial cross-cultural differences that are evident in the literature. We pose basic questions such as: (1) What does self-esteem "look" like in Chinese children? (2) How do childrearing practices in China influence the development of self-esteem in children? And, (3) what are the limitations of cross-cultural research in understanding a phenomenon such as self-esteem? We suggest that self-esteem does not "mean" the same things across these collectivist and individualistic cultures. We conclude our discourse with specific recommendations for clinical theory, research, and practice.

The physical conditions experienced by reptile embryos inside natural nests can influence the size, shape and behaviour of the resultant hatchlings. Although most reptiles are tropical, the effects of incubation temperatures on offspring phenotypes have received little attention in tropical species. The consequences of differences in thermal variance during incubation on offspring were studied in a tropical natricine snake (the Keelback Tropidonophis mairii), which lays eggs in soil cracks of varying depths. Some 253 eggs from 19 clutches were incubated under two thermal regimes with identical mean temperatures (25.6 degreesC), but temperatures in the 'variable' treatment fluctuated more (21.8-29.6 degreesC) than those in the 'constant' temperature treatment (25.2-26.5 degreesC). These thermal regimes were similar to those of shallow (20 cm deep) and deep (40 cm deep) soil cracks, respectively, and represent thermal conditions inside natural nests and potential nest sites. Incubation temperatures affected body size, shape and antipredator behaviour of hatchling snakes. Snakes from constant temperature incubation were longer and thinner than snakes from high variance incubation. Clutch effects influenced all offspring traits, with significant interactions between clutch of origin and incubation treatment for body size, but not swimming speed or behaviour. 4. There was a significant interaction between incubation treatment and offspring sex on neonate swimming speed. Incubation under cycling thermal regimes significantly increased swimming speeds of females, but had little effect on males. Such sex differences in phenotypic responses of hatchling snakes support a major assumption of the Charnov-Bull hypothesis for the evolution of temperature-dependent sex determination.

Hydroxyapatite coatings can be readily deposited on metal substrates by electrophoretic deposition. However, subsequent sintering is highly problematic owing to the fact that temperatures in excess of 1100°C are required for commercial hydroxyapatite powders to achieve high density. Such temperatures damage the metal and induce metal-catalysed decomposition of the hydroxyapatite. Furthermore, the firing shrinkage of the hydroxyapatite coating on a constraining metal substrate leads to severe cracking. The present study has overcome these problems using a novel approach: the use of aged nanoparticulate hydroxyapatite sols (lower sintering temperature) and a dual coating strategy that overcomes the cracking problem. Dual layers of uncalcined hydroxyapatite (HAp) powder were electrophoretically coated on Ti, Ti6Al4V and 316L stainless steel metal substrates, sintered at 8751000°C, and characterised by SEM and XRD, and interfacial shear strength measurement. Dual coatings on stainless steel had an average high bond strength (about 23 MPa), and dual coatings on titanium and titanium alloy had moderate strengths (about 14 and 11 MPa, respectively), in comparison with the measured shear strength of bone (35 MPa). SEM and XRD demonstrated that the second layer blended seamlessly with the first and filled the cracks in the first. The superior result on stainless steel is attributed to a more appropriate thermal expansion match with hydroxyapatite, the thinner oxide layer, or a combination of these factors.

Mouse immunoglobulin (Ig) molecules have previously been shown to bind to the surface of CD5 B cells from patients with B-cell chronic lymphocytic leukemia (B-CLL). The results indicated that surface IgM was involved in the interaction and suggested the phenomenon was an example of the polyreactive binding capacity of the surface Ig (sIg) expressed by these malignant cells. This article describes the further characterization of the interaction between human IgM and mouse Ig molecules and subunits. Mouse Ig molecules of both kappa and lambda light chain classes bound to the B-CLL cell surface. The dissociation constant for the interaction of mouse IgG1 (K121) with the B-CLL cell surface was 3.6 107 M. To confirm the involvement of the human IgM expressed by the B-CLL cells in the interaction, the malignant cells were stimulated in vitro to induce secretion of human IgM. Enzyme immunoassay was used to show that secreted human IgM bound to intact mouse Ig, as occurred with the cell surface analysis. The mouse Ig epitope recognized by the purified secreted human IgM was shown by Western blot analysis to be located on the light chain of the mouse Ig molecule and to be conformationally dependent. K121 light chain was cloned and expressed in E. coli and the recombinant light chain bound to the surface of CLL B cells. The results confirm that human IgM is the reactive ligand in the interaction with mouse Ig and indicate that the interaction of polyreactive IgM with mouse IgG occurs via the light chain component of IgG.

Over the past 20 years, discharge of water from the United States to the delta of the Colorado River in Mexico has regenerated native trees that now account for 23% of vegetation in a 100-km, non-perennial, stretch of river below Morelos Dam at the United StatesMexico border. The discharges are associated with the filling of Lake Powell, the last large reservoir to be constructed on the river, and with ENSO cycles that bring extra winter and spring precipitation to the watershed. The discharges below Morelos Dam produce overbank floods that germinate new cohorts of Populus fremontii andSalix gooddingii trees. Relatively little flood water from the United States is required to support a pulse flood regime that can result in regrowth of native vegetation in the delta. Based on analysis of past flows and existing tree populations, we estimate that a FebruaryApril flow of 3×109m3at 80120 m3s-1is sufficient to germinate and establish new cohorts of native trees. However, there was a positive correlation between frequency of flows and total vegetation cover over the years 19921999, showing that more frequent flows would further increase vegetation cover. The results support the importance of pulse floods in restoring the ecological integrity of arid-zone rivers.

View description>>

The effect of nickel on two classes of martensitic-type transformations in platinum systems has been studied. The first transformation is L12 to DOc' in the Pt3Al system and the second is B2 to B19 in the TiPt system. The microstructures after transformation in the two systems are very different. The product of the Pt3Al transformation has a twinned microstructure, typical of cubic-to-tetragonal transformations. The product of the TiPt transformation is lath-like, although the morphology can he altered using heat treatments. The parent phase in the TiPt system is not retained at room temperature, whereas the parent phase in the Pt3Al transformation can he stabilised to room temperature. A great variation in hardness and transformation temperature is seen in each system as the composition is varied about the stoichiometric ratio, which has the lowest hardness. The Pt3Al transformation temperature has been reported to range from around room temperature to 1000°C. The TiPt transformation temperature can range from 1000 to 1080°C. The effect of nickel additions on these alloys also has a marked effect on the parent and product phase stability, and hence the microstructure and resulting hardness. The effect on the Pt3Al phase is complex, as nickel appears to stabilise the parent phase. The hardness varied in the region of 350 to 500 HV10. For the TiPt phase, the hardness values were generally found to increase with the nickel additions increasing from 250 to about 600 HV10. The addition of 20 at.% nickel decreases the transformation temperature from around 1000°C to about 600°C.

A study of genes that control the initiation of flowering in plants, taking Arabidopsis as a model, was presented. It was found that in naturally occuring ecotypes of Arabidopsis that come from high mountains or high latitudes and require vernalization to flower, there is normally a high level of activity of the FLC gene. In varieties from near the equator, which don't respond to vernalization, there is a low level of FLC activity.

This study examines the effect of implantation and annealing parameters on the formation of Ge crystallites in ion-implanted silica. Samples were implanted at room temperature or -196°C with 1.0 MeV Ge+ ions to fluences in the range from 0.6 to 3×1017 Ge.cm-2. Ge nanocrystals were not observed in samples implanted at -196°C but were observed in samples irradiated at room temperature. Nanocrystals were observed in all samples after annealing and their size distribution was found to be almost independent of the implant fluence. The distributions were also shown to be asymmetrical with depth, with smaller nanocrystals located on the near-surface side of the implant distribution.

View description>>

The deformation behavior of as-grown and ion-beam-modified wurtzite GaN films is studied by nanoindentation with a spherical indenter. Atomic force microscopy (AFM) and cathodoluminescence are used to characterize the deformation mode. No systematic dependence of the mechanical properties on the film thickness (at least for thicknesses from 1.8 to 4 μm) as well as on doping type is observed. Results strongly suggest that (i) slips is the major contributor to the plastic deformation of crystalline GaN and (ii) slip nucleation (rather than a phase transformation) is responsible for "pop-in" events observed during loading. Indentation with an ∼ 4.2 μm radius spherical indenter at maximum loads up to 900 mN does not produce any cracking visible by AFM in crystalline GaN. Instead, under such loads, indentation results in a pronounced elevation of the material around the impression. Implantation disorder dramatically changes the deformation behavior of GaN. In particular, implantation-produced defects in crystalline GaN suppress (i) "pop-in" events during loading, (ii) slip bands observed by AFM, and (iii) the plastic component of deformation. GaN amorphized by ion bombardment exhibits plastic flow even for very low loads. The values of hardness and elastic modulus of amorphous GaN are dramatically reduced compared to those of as-grown GaN.

View description>>

It is well known that under high pressure conditions, microdischarges in rare gases or rare gas/halogen mixtures produce excimers. Excimers do not possess a stable ground state and tend to decay rapidly, releasing in the process radiation in the VUV, UV, or even visible range. The radiation generated by excimer lamps is incoherent, but intense and spectrally selective. Therefore, excimer lamps have been used in numerous applications such as surface modification, paint curing, material deposition, and pollution abatement. In this paper, we report a series of experiments on the use of a Dielectric Barrier Discharge (DBD) based excimer UV lamp to decontaminate water (both fresh and salty). The lamp presents a large area with a cylindrical geometry, and is RF-driven. In our experimental setup, the lamp is immersed into about a half liter of water containing a pre-selected concentration of a specific microorganism. The volume of water is exposed to the UV radiation emanating from the lamp and samples are taken, at selected time intervals, for analysis. The microorganisms used in our experiments are Escherichia coli, Bacillus subtilis, and Salmonella typhimurium, all bacteria, and the dinoflagellate Gymnodinium catenatum. Kill curves showing viability versus treatment time will be presented. In addition, a characterization of the morphological changes of the treated cells will be attempted.

The Third Comparison of Mesoscale Prediction and Research Experiment (COMPARE) workshop was held in Tokyo, Japan, on 13-15 December 1999, cosponsored by the Japan Meteorological Agency (JMA), Japan Science and Technology Agency, and the World Meteorological Organization. The third case of COMPARE focuses on an event of explosive tropical cyclone [Typhoon Flo (9019)] development that occurred during the cooperative three field experiments, the Tropical Cyclone Motion experiment 1990, Special Experiment Concerning Recurvature and Unusual Motion, and TYPHOON-90, conducted in the western North Pacific in August and September 1990. Fourteen models from nine countries have participated in at least a part of a set of experiments using a combination of four initial conditions provided and three horizontal resolutions. The resultant forecasts were collected, processed, and verified with analyses and observational data at JMA. Archived datasets have been prepared to be distributed to participating members for use in further evaluation studies. In the workshop, preliminary conclusions from the evaluation study were presented and discussed in the light of initiatives of the experiment and from the viewpoints of tropical cyclone experts. Initial conditions, depending on both large-scale analyses and vortex bogusing, have a large impact on tropical cyclone intensity predictions. Some models succeeded in predicting the explosive deepening of the target typhoon at least qualitatively in terms of the time evolution of central pressure. Horizontal grid spacing has a very large impact on tropical cyclone intensity prediction, while the impact of vertical resolution is less clear, with some models being very sensitive and others less so. The structure of and processes in the eyewall clouds with subsidence inside as well as boundary layer and moist physical processes are considered important in the explosive development of tropical cyclones.

Simple quantitative performance criteria are developed for translucent materials in terms of hemispherical visible transmittance, and angular spread of transmitted luminance using a half angle. Criteria are linked to applications in luminaires and skylights with emphasis on maximising visible throughput while minimising glare. These basic criteria are also extended to angle of incidence changes which are substantial. Example data is provided showing that acrylic pigmented with spherical polymer particles can have total hemispherical transmittance with weak thickness dependence, which is better than clear sheet, while the spread of transmitted light is quite thickness-sensitive and occurs over wider angles than inorganic pigments. This combination means significantly fewer lamps can achieve specified lux levels with low glare, and smaller skylights can provide higher, more uniform daylight illuminance.

The recent discovery that electromagnetic radiation can transmit super-efficiently through sub-wavelength holes in metal films and thin metal foils has implications for solar energy and energy efficiency technologies, especially thin metal films and metal particle arrays. The effect involves light induced surface plasmons coupling through the holes to form new states which can resonantly absorb and re-emit photons. They are a virtual bound state for photons. The material must have a dielectric constant below -1, and for noble metals enhancement is strong beyond (lambda) approximately 0.7 micrometers , with a long wavelength limit set by absorption losses, well into the black body spectral range. In aluminium the strong onset is in the visible. Thus control of solar heat gain and thermal radiation can utilize this effect. Broad band or narrow band spectral selectivity are possible, depending on metal thickness and how the holes are arranged with respect to each other. Very interesting effects occur in multilayers, with standard multilayer thin film optics not applying when this phenomena is present. An admittance approach to handling thin film optics in the presence of surface plasmon coupling is addressed.

© 2001 Optical Soc. Of America. Summary form only given. Microstructured optical fibers (MOFs) are among the most exciting recent developments in fiber optics. Typically these consist of a glass core surrounded by circular airholes running parallel to the fiber. MOFs have properties that can differ substantially from conventional step-index fibers, such as unusual dispersion characteristics, low or high effective nonlinearities, and many others. The number of air holes can be as small as six, in which case the energy confinement is imperfect and the modes are leaky. More generally, all modes of MOFs with a finite number of holes and no other confinement mechanism, are leaky.Here we report a multipole expansion method for full-vector modal calculations of MOFs with circular holes. Since this is the natural type of expansion for structures with circular inclusions, it is very efficient.

Introduction- Background. The child support scheme was introduced in April 1993 under the auspices of the Child Support Act 1991. Despite a series of incremental adjustments to the scheme in its early years, it became widely recognised that the system had failed to acheive its original goals and in particular to improve financial support for children. A series of major reforms to the child support system are being implemented (mostly with effect from April 2002) as a result of the Child Support, Pensions and Social Security Act 2000. The goals of the reforms include making the system accessible, comprehensible and responsive to the parents concerned. Other objectives include increasing compliance and the administrative efficiency of the child support scheme.

Research Paper Number: 51 Abstract: The analysis of diffusion process in financial models is crucially dependent on the form of the drift and diffusion coefficient functions. A methodology is proposed for estimating and testing coefficient functions for ergodic diffusions that are not directly observable. It is based on semiparametric and nonparametric estimates. The testing is performed via the wild bootstrap resampling technique. The method is illustrated on S&P 500 index.

Research Paper Number: 61 Abstract: The paper presents a financial market model that generates stochastic volatility using a minimal set of factors. These factors, formed from transformations of square root processes, model the dynamics of different denominations of a benchmark portfolio. Benchmarked prices are assumed to be local martingales. Numerical results for the pricing and hedging of basic derivatives on indices are described. This includes cases where the standard risk neutral pricing methodology fails. However, payoffs can be perfectly hedged using self-financing strategies and a form of arbitrage still exists. This is illustrated by hedge simulations. The term structure of implied volatilities is documented.

Research Paper Number: 48 Abstract: The paper proposes a financial market model that generates stochastic volatilities and stochastic interest rates using a minimal number of factors that characterise the dynamics of different denominations of a benchmark portfolio. It models asset prices essentially as functionals of square root and Ornstein-Uhlenbeck processes. The resulting price processes exhibit stochastic volatility with leptokurtic log-return distributions that closely match those observed in reality. The benchmark portfolio is negatively correlated with its volatility which models the well-known leverage effect. The average growth rates of the different denominations of the benchmark portfolio are Ornstein-Uhlenbeck processes which generates the typically observed long term Gaussianity of log-returns of asset prices.

Research Paper Number: 72 Abstract: This paper introduces a benchmark approach for the modelling of continuous, complete financial markets when an equivalent risk neutral measure does not exist. This approach is based on the unique characterization of a benchmark portfolio, the growth optimal portfolio, which is obtained via a generalization of the mutual fund theorem. The discounted growth optimal portfolio with minimum variance drift is shown to follow a Bessel process of dimension four. Some form of arbitrage can be explicitly measured by arbitrage amounts. Fair contingent claim prices are derived as conditional expectations under the real world probability measure. The Heath-Jarrow-Morton forward rate equation remains valid despite the absence of an equivalent risk neutral measure.

Research Paper Number: 71 Abstract: Models which postulate lognormal dynamics for interest rates which are compounded according to market conventions, such as forward LIBOR or forward swap rates, can be constructed initially in a discrete tenor framework. Interpolating interest interest rates between maturities in the discrete tenor structure is equivalent to extending the model to continuous tenor. The present paper sets forth an alternative way of performing this extension; one which preserves the Markovian properties of the discrete tenor models and guarantees the positivity of all interpolated rates.
