The commercially available volatile anesthetic fluroxene (2,2,2-trifluoroethyl vinyl ether) which contains the stabilizer N-phenyl-1-napthylamine, was tested for mutagenicity using four strains of S. typhimurium, TA1535, TA1537, TA98 and TA100, and one strain of E. coli, WP2. In addition, purified fluroxene; N-phenyl-1-napthylamine; trifluoroethanol, a major metabolite of fluoroxene; and urine from rats anesthetized with fluroxene were tested. Several procedures were utilized including exposure of bacteria to vapor in desiccators and in liquid suspension. Results indicate that fluroxene, but not its stabilizer, was mutagenic to strains TA1535, TA100 and WP2 only in liquid suspension and only in the presence of a rat-liver enzyme system. Trifluoroethanol and urine from fluroxene-treated rat were not mutagenic to any strain of bacteria. These findings indicate that fluroxene is a promutagen which requires preincubation before it is recognized. Further experiments were performed with enzymes prepared from mouse, hamster and human liver. Fluroxene was mutagenic only in the presence of enzymes prepared from Aroclor 1254 pretreated rodents. Since fluroxene was not mutagenic in the presence of enzymes prepared from three human livers, the significance of these findings to man are unclear.

Sequential confidence intervals for the parameters of a subpopulation of a finite population are studied. Procedures are suggested using the mean, median, and trimmed means; these procedures are shown to be more efficient than their counterparts which are based on independent, identically distributed observations from infinite populations. The major technique used is to “linearize” the estimates, yielding as a simple consequence proofs of central limit theorems. A Monte Carlo study shows that the small-sample performance is very good. © 1978, Taylor & Francis Group, LLC.

AbstractResults concerning a class of lacunary sets are generalized from compact abelian to compact nonabelian groups. This class was introduced for compact abelian groups by Bozejko and Pytlik; it includes the p-Sidon sets of Edwards and Ross. A notion of test family is introduced and is used to give necessary conditions for a set to be lacunary. Using this, it is shown that (2) has no infinite p-Sidon sets for 1 ≤p<2.

AbstractA limited area, six‐level, primitive equations numerical weather prediction model has been developed to provide improved 24‐ to 36‐hour forecasts for the Australian region. Important features of the model include semi‐implicit time differencing, and a nesting procedure which enables boundary values to be updated from a hemispheric spectral model. Preliminary results from the model indicate considerable operational potential.

The Cretaceous Whangakea Basalt has undergone two episodes of alteration. The earlier one pervasively affected part of the formation and produced greenschist mineral facies assemblages of the type quartz-albite-chlorite-epidote-actinolite-sphene. The later episode gave rise to zeolites, including stilbite, analcime, thomsonite, epistilbite, heulandite-clinoptilolite, and laumontite, none of which co-exist stably wth quartz. Products of the zeolitic alteration are widespread, but occur predominantly in and adjacent to veins. Calcite crystallised at a late stage in this episode. Greenschist alteration probably occurred at temperatures in excess of 320°c, whereas zeolite alteration is believed to have taken place below 165–180°c. The Whangakea Basalt, together with an associated gabbro-peridotite body, constitute an ophiolite complex. The localised development of the greenschist alteration, the presence of relic magmatic phases, the lack of preferred orientation of the secondary minerals, and their common pseudomorphous habit suggest that this alteration resulted from hydrothermal metamorphism. Zeoli tic alteration may have occurred late in this metamorphism, or may have occurred while the basaltic rocks were buried beneath some 3000 m of Tertiary strata. © 1978 Taylor & Francis Group, LLC.

Olistostromes found in a number of major fold belts are of an age comparable with the start of underthrusting as indicated by attendant arc-related volcanism. They occur at the inner edge of inferred accretionary wedges, and are commonly associated with contemporaneous basaltic rocks. These olistostromes may result from disruption of the crust during lithosphere fracturing at the commencement of subduction. Components of the olistostromes provide evidence concerning the site of initial underthrusting. © ASEG 1978.

Five deformational "episodes" (D1-D5) during which folds and associated cleavages formed, and a later period of faulting dominated by strike-slip movements, comprise the structural sequence in the Nambucca slate belt. D1 structures are most widespread and involved greatest strain; D2-D4 structures have affected progressively smaller areas and indicate progressively smaller strains. Strong compressive stresses during D1 produced horizontal shortening and vertical extension, and the D2-D4 structures result from adjustments to this initial strain. Regional metamorphism accompanied D1, and D1 strain is greatest in the more highly metamorphosed rocks. Some granitic bodies were probably emplaced at this time, but most plutons rose only after folding had ceased. Orogenesis, as indicated by folding and regional metamorphism lasted less than 10 m.y., but faulting continued for at least another 30 m.y. The slate belt accumulated close to a consuming plate margin, but deformation commenced only after subduction ceased, with compressive stresses generated by coupling across the former plate boundary. The development of a wrench regime during D5, and its continued existence during a long period of faulting, suggests either that the consuming plate boundary was replaced by a transform fault, or that subduction stepped oceanward and underthrusting was obliquely directed. © 1978.

Newly synthesized rat islet proteins have been analyzed by polyacrylamide slab gel electrophoresis and fluorography. A minor component having an apparent molecular weight of 11,100 was identified as preproinsulin by the sensitivity of its synthesis to glucose, the pattern of NH2-terminal leucine residues, and the rapidity of its appearance and disappearance during incubation of islets or islet cell tumors. A small amount of labeled peptide material which may represent the excised NH2-terminal extension of preproinsulin or its fragment was also detected. The kinetics of formation and processing of the preproinsulin fraction were complex, consisting of a rapidly turning over component having a half-life of about 1 min and a slower minor fraction that may have bypassed the normal cleavage process. The electrophoretic resolution of the preproinsulin and proinsulin fractions into two bands each is consistent with the presence of two closely related gene products in rat islets rather than intermediate stages in the processing of these peptides.

AbstractIn this paper we use a simple numerical model to study vortex growth in a flow configuration which broadly simulates the principal characteristics of a severe tornadic storm system, i.e. strong vertical forcing by intense cumulus or cumulonimbus convection in the presence of an organized field of rotation on the cloud scale. The model is similar to one described by L. M. Leslie in which the updraught in the main cloud cell is modelled by an imposed body force, but differs in that the rotation field is determined by specifying the vertical profile of swirling velocity at the lateral boundary of the flow domain and air is allowed to enter or leave the computational region through its radial and upper boundaries. In particular, we compare situations in which the imposed swirl is concentrated aloft, primarily above cloud base, and when it extends to lower levels. In the former case, solutions exhibit genesis to a steady suspended vortex provided that the forcing strength lies within a certain range, depending on the level of rotation. However, if the imposed swirl extends sufficiently far below cloud base, the vortex continues its downward growth and establishes contact with the ground.We believe our results provide a plausible and consistent picture of the growth of a tornado beneath the main updraught of a severe thunderstorm and indicate why only a relatively small proportion of such clouds spawn pendant funnel clouds and why only a fraction of these develop into tornadoes. Moreover, they appear to be consistent with the observed development of circulation patterns deduced from single‐pulse Doppler radar measurements of a tornado‐producing storm system by Burgess, Lemon and Brown.
