Summary This paper presents an overview of the computer systems, and their interconnections, being installed on the northern North Sea platforms and pipelines operated by Shell U.K. E and P on behalf of Shell and Esso. The problems associated with the introduction of these problems associated with the introduction of these facilities on operational platforms are discussed and the prospects for the future are outlined. prospects for the future are outlined. Introduction Shell U.K. E and P has installed and now operates eight production platforms in the northern North Sea. It also production platforms in the northern North Sea. It also acts as operator of two major pipeline networks, an oil pipeline network to the oil terminal at Sullom Voe, and a pipeline network to the oil terminal at Sullom Voe, and a gas pipeline system to St. Fergus on the Scottish mainland. Originally the platforms were designed without any centralized data-collection, processing, or storage mechanisms. The potential difficulties of operating a combined drilling and production platform and of coordinating these activities on a number of sites have now been recognized. This coordination task has been made more difficult because other oil companies in the North Sea have fight of access to the transportation facilities of the pipelines, while as operator Shell retains responsibility for the technical integrity of these facilities. A complex computer network has been designed and installed to assist these operational and coordination tasks. This paper outlines these computer systems and describes some of the difficulties of their design, installation, and commissioning.

AbstractThe effect of an isolated topographic bump in a two-layer fluid on a β-plane is investigated. An analytical solution is derived in terms of the appropriate Green's function for arbitrary topography of finite horizontal extent. It is found that the disturbances generated by the bump are composed of two fundamental modes which may be wave-like or evanescent. The wave-like modes are topographically induced Rossby waves which occur only when there is eastward flow in at least one of the layers. These waves are always confined to the downstream (eastward) side of the bump. Whereas previous studies of this type have concentrated on eastward flow over topography, the theory has been extended here to include a wide range of vertically sheared flows. Particularly important is the case of low level westward flow combined with upper level eastward flow, as it has direct application, for example, to the summertime atmospheric circulation over the sub-tropical regions of the continental land.masses. In this case a wave-like disturbance extends far downstream from the bump for sufficiently large shear, and is of smaller amplitude in the upper layer than in the lower layer because of the effects of the stratification. For small shears, the wave-like mode in the lower layer is small and the character of the disturbance is evanescent, confining it to the immediate neighbourhood of the bump. A stability analysis of the solutions shows that the disturbances may be baroclinically unstable for sufficiently large mean shear.

Increasing levels of resistance to tetracycline and to a number of other unrelated antibiotics, including chloramphenicol, beta-lactams, puromycin, and nalidixic acid, occurred in Escherichia coli after 50 to 200 generations of growth in the presence of subinhibitory concentrations of tetracycline or chloramphenicol. In the absence of selective pressure, resistances fell to low levels within 100 generations of growth. This amplification of resistance was observed in laboratory and naturally occurring E. coli strains as well as in polA and recA strains. With the exception of previously identified cmlA and cmlB mutations, tetracycline or chloramphenicol resistances were not P1 transducible. Coincident with the emergence of resistance was the appearance of a previously cryptic energy-dependent efflux system for tetracycline. The expression of resistance phenotypes and the tetracycline efflux system were temperature sensitive at 42 degrees C.

In Escherichia coli K-12, amplifiable resistance to tetracycline, chloramphenicol, and other unrelated antibiotics was mediated by at least four spatially separated loci. Tetracycline-sensitive mutants were isolated by Tn5 insertional inactivation of an amplified multiply resistant strain. One of these, studied in detail, showed coordinate loss of expression of all other resistance phenotypes. The Tn5 element in this mutant mapped to 34 min on the E. coli K-12 linkage map. We have designated the locus marA (multiple antibiotic resistance). Tetracycline-sensitive mutants containing marA::Tn5 regained all resistance phenotypes at frequencies of 10(-8) to 10(-7) upon precise excision of Tn5. Moreover, a newly described tetracycline efflux system (A. M. George and S. B. Levy, J. Bacteriol. 155:531-540, 1983) was inactivated in tetracycline-sensitive mutants, but recovered in tetracycline-resistant revertants. In merodiploids, F-prime marA+ expressed partial or complete dominance over corresponding mutant chromosomal alleles. Dominance tests also established that a previously amplified host and a mutant marA allele were preconditions for the expression of phenotypic resistances.

The hypotheses that grazing losses and/or ambient inorganic nitrogen concentrations control the standing crop of the epilithic algal community were tested in two habitats at One Tree Reef (Great Barrier Reef, Australia). Short (12-15 days) and long (167-306 days) multifactorial experiments using grazer exclusion and nitrogen fertilization treatments were used to partition variance in algal community biomass on portable segments of natural reef substratum during 1980. On outer reef slopes, inorganic nitrogen limited algal community growth, but the standing crop was determined by grazing losses. In the subtidal lagoon inorganic nitrogen and grazing alternated seasonally in controlling standing crop. The recolonization of cleared natural substratum was followed at two additional sites. The algal standing crop in subtidal habitats reached control levels within 4 months, while that in an intertidal reef habitat took up to 14 months. The standing crop of benthic algae on natural reef substrata was monitored in all habitats over 2 yr. In shallow and intertidal habitats, the standing crop was three to five times higher than in deeper areas, and showed a spatial and seasonal variation apparently controlled by factors other than grazing intensity, despite high levels of yield to grazers. Seasonal variation was much less in subtidal habitats. It is concluded that only within limited temporal and spatial scales is grazing intensity alone an adequate predictor of benthic algal standing crop. © 1983.

ABSTRACTThe purpose of this research is to show the usefulness of three relatively simple nonlinear classification techniques for policy‐capturing research where linear models have typically been used. This study uses 480 cases to assess the decision‐making process used by 24 experienced national bank examiners in classifying commercial loans as acceptable or questionable. The results from multiple discriminant analysis (a linear technique) are compared to those of chi‐squared automatic interaction detector analysis (a search technique), log‐linear analysis, and logit analysis. Results show that while the four techniques are equally accurate in predicting loan classification, chi‐squared automatic interaction detector analysis (CHAID) and log‐linear analysis enable the researcher to analyze the decision‐making structure and examine the “human” variable within the decision‐making process. Consequently, if the sole purpose of research is to predict the decision maker's decisions, then any one of the four techniques turns out to be equally useful. If, however, the purpose is to analyze the decision‐making process as well as to predict decisions, then CHAID or log‐linear techniques are more useful than linear model techniques.

Temporal changes in the colonization of settlement plates by algae were determined for an Ecklonia radiata (C. Ag.) J. Ac community. Relative covers of individual algal types were recorded on plates that were exposed for short periods (2 weeks) and then taken to the laboratory. Sets of plates were examined each month from April 1981 to March 1982. Marked seasonal changes were detected in the total cover of algae, the relative covers of individual algal types and the diversity of the colonizing community (as measured by the Shannon-Weaver diversity index and the number of algal types). Advantages and disadvantages of this method and other methods to determine the structure of the colonizing community are discussed. It is concluded that, in addition to examining subsequent biological processes, future studies on the dynamics of kelp communities should also estimate temporal variation in the settlement of algae. © 1983.

The importance of algae, both as a contribution to the understanding of living things and in practical terms, hardly needs stressing today. Despite the previous emphasis on photosynthesis research in land plants there is now a large corpus of work on algae. This chapter intends to bring much of the dispersed literature together, so as to achieve an integrated framework from which conclusions can be drawn to further stimulate research. Organisms from the borderline of groups loosely called prokaryotes, plants, and animals have been discussed along with how the majority of algae are influenced by the light climate properties. The structure and function of the photosynthetic membrane have been described. Various kinds and levels of light harvesting available to algae are reviewed briefly. A more detailed analysis of some biochemical and biophysical aspects of light harvesting are also given. Light is essential to all photosynthetic autotrophs. But it is only to the extent that light is limiting to growth that light-harvesting strategies become important. It is therefore necessary to consider under what conditions light does become limiting for algal growth. Strategies of light harvesting are discussed in terms of general ecological, taxonomic, morphological, and cytological aspects. The chapter looks into photosynthetic pigments, reaction centre complexes, and pigment protein (light-harvesting) complexes with details of the principles of light harvesting in light of quantum chemistry and transfer of excitation energy, structure and function, distribution of excitation energy between the photosystems, and interaction of the light-harvesting apparatus with other photosynthetic processes. © 1983, Academic Press Inc.

A common definition of physics is the study of matter and energy and their interrelationship. Energy was soley in the domain of the physical scienties until, in 1973, politicans 'discovered' the word. Often students have the impression that energy was invented in 1973, or at best it was poorly understood before then. Hence the current awareness of the important of energy has obvious implications for physics departments everywhere. To properly understand energy and its role in all societies, it is neccesary to look at mankinds use of energy not just as it is in present but throughout history.

Male and female Swiss Webster (SW) mice, age 13 to 14 weeks, were exposed by inhalation for 4 hr per day, 5 days per week, for 14 weeks, to either room air, 0.5% nitrous oxide, 5.0% nitrous oxide, or 50% nitrous oxide. Murine germ cells were examined for evidence of injury after this exposure. A group of male mice were treated with methyl methanesulfonate (MMS) as a positive control for sperm abnormalities while a group of female mice were treated with 3-methylcholanthrene (3-MC) as a positive control for oocyte destruction. There were no significant differences among the four inhalation exposure groups in testes weight, percentage of abnormally shaped sperm, sperm count, or histologic appearance of the testes; the mean percentage (+/- SE) of abnormal sperm ranged from 8.9 +/- 2.4 (5.0% nitrous oxide) to 13.5 +/- 0.5 (50% nitrous oxide) with a concurrent control value of 10.4 +/- 2.3%. In the positive control experiment, 25.2 +/- 4.1% of sperm from mice treated with MMS were abnormal compared with 2.5 +/- 0.3% of sperm from mice treated with saline (p less than 0.001), indicating that sperm of SW mice are sensitive to chemical damage. There was no significant difference between the mean number of oocytes in mice treated with 50% nitrous oxide (33.3 +/- 14.4) and in control mice (29.8 +/- 8.0). In the positive control experiment, mice treated with 3-MC had significantly fewer (p less than 0.001) primordial oocytes, 67.2 +/- 19.5 compared with control mice, 222.4 +/- 21.9, indicating that this strain is sensitive to chemical damage of the ovary. Thus, murine germ cells showed no evidence of toxic effects due to prolonged exposure to nitrous oxide.

Multi-resistant Entcrobacteriaceae and Pseudomonas isolated from clinical specimens at RNS were characterized for resistance phenotype and transferred resistant phenotype. These isolates were obtained over a two year period from different specimens and from patients with varying clinical syndromes. Twenty-six of these isolates were further characterized with respect to their aminoglycoside modifying enzymes. Only three enzymes were detected: AAC(3)-I, APH(3>I and AAD (2' ')-II. The substrate range of these enzymes was investigated and not always found to coincide with the transferred phenotype. AAD(2' ')-II was found only in association with APH(3'H and not alone. The substrate range of AAC(3)-I from Pseudomonas was different from AAC(3)-I from Enterobacteriaceae but not sufficiently dissimilar to classify them as separate isoenzymes. The relatively few aminoglycoside-inactivating enzymes suggest that within this hospital there may be a limited gene pool for these enzymes. © 1983 The British Society for Antimicrobial Chemotherapy.

View description>>
Thylakoid membrane preparations active in photosynthetic electron transport have been obtained from two marine red algae, Griffithsia monilis and Anotrichium tenue. High concentrations (0.5-1.0 M) of salts such as phosphate, citrate, succinate and tartrate stabilized functional binding of phycobilisomes to the membrane and also stabilized Photosystem II-catalysed electron-transport activity. High concentrations (1.0 M) of chloride and nitrate, or 30 mM-Tricine/NaOH buffer (pH 7.2) in the absence of salts, detached phycobilisomes and inhibited electron transport through Photosystem II. The O2-evolving system was identified as the electron-transport chain component that was inhibited under these conditions. Washing membranes with buffers containing 1.0-1.5 M-sorbitol and 5-50 mM concentrations of various salts removed the outer part of the phycobilisome but retained 30-70% of the allophycocyanin ‘core’ of the phycobilisome. These preparations were 30-70% active in O2 evolution compared with unwashed membranes. In the sensitivity of their O2-evolving apparatus to the composition of the medium in vitro, the red algae resembled blue-green algae and differed from other eukaryotic algae and higher plants. It is suggested that an environment of structured water may be essential for the functional integrity of Photosystem II in biliprotein-containing algae.
