    Description / Table of Contents: Zusammenfassung Im Dezember 1975 wurden durch eine Fesselballonsonde die vertikalen Temperatur- und Windprofile im Gore River Valley im westlichen Colorado ermittelt. Aus Beobachtungen an einem wolkenlosen Morgen bei einer anfangs starken Inversion im Tal zeigte sich, daß die Inversionsobergrenze stetig um 120 m Std−1. absank und nach ungefähr vier Stunden den Talgrund erreichte. Schwache Talabwinde wehten innerhalb der Inversionsschicht. während stärkere Talaufwinde oberhalb derselben herrschten. Eine Hypothese wird vorgeschlagen, um diese Beobachtungen zu erklären. Die Abkühlung am späten Nachmittag und am Abend, wobei die Bildung einer Inversion einsetzte, deren Schichtdicke in weniger als zwei Stunden 175 m betrug, ist Gegenstand einer gesonderten Untersuchung. Winde innerhalb der Inversionsschicht wurden nicht mehr von den Winden in der freien Atmosphäre beeinflußt und blieben im Laufe der Nacht sehr schwach. Bewölkung während der Erwärmungsperiode an einem Morgen hatte zur Folge, daß das Temperaturprofil sich Isothermie näherte, indem Erwärmung gleichmäßig im ganzen Luftraum des Tales sich fortsetzte.
    Notes: Summary A tethered balloon sounder was used to collect vertical temperature and wind structure data in the Gore River Valley of Western Colorado during December, 1975. Observations taken on a clear morning in which a deep inversion was initially present in the valley showed that the inversion top descended at a steady rate of ∼120 m hr−1. reaching the valley bottom after approximately 4 hours. Weak down-valley winds were present within the inversion layer while stronger up-valley winds prevailed above. A hypothesis is presented to account for these observations. A case study is presented for afternoon and evening cooling in which a ground-based inversion developed to a depth of 175 m in less than 2 hours. Winds within the inversion became decoupled from the synoptic-scale winds and remained very weak during the night. The effect of cloud cover during a morning heating cycle was to make the temperature soundings approach isothermal while sensible heating continued throughout the valley volume.

    Notes: Abstract A new experiment is described to advance the mechanistic description of fast thermal decomposition chemistry related to preignition and ignition. The technique is illustrated with data for ethylenediammonium dinitrate which displays separable thermochemical events in the condensed phase that correlate with the nature of the products evolved to the gas phase.

    Notes: Abstract Pioneer 11 and 10 observations of the wave structure seen in a corotating interaction region at 2.5 AU on day 284 of 1973 and 8 days later at 5 AU reveal large-amplitude Alfvénic structures with many detailed correlations seen between their features at the two radial distances. Hodogram analysis suggests the dominance of near plane polarized, transverse Alfvénic mode fluctuations with periods between 2 min and one hour or more. Some wave evolution close to the Corotating Interaction Region (CIR) shock is noticed, but waves towards the centre of the compression seem to propagate with little damping between the spacecraft observation positions.

    Notes: Abstract Swarming locusts show three physical criteria, i.e. the phase changes of melanisation of the nymphal stages or hoppers, of the proportions of certain body parts (morphometric ratios), and increased genetic recombination (meiotic chiasma frequencies) in the adult. The control of these changes, initiated by aggregation into swarms, i.e. gregarisation, seems to be vested in a pheromone which is produced by all hoppers in both the solitaria and gregaria phases, also by hoppers of the albino strain. Such a pheromone can be extracted from the locust room air and from the locust, these extracts showing high activity in bioassays, primarily in increased chiasma frequencies but also in hopper colour. The extract in risella oil is more efficient than that in petroleum ether and can be distilled to yield an active distillate. The pheromone is secreted in the faeces of hoppers but not of adults. There is evidence in faeces bioassays that all three physical criteria are affected; the pheromone may be called locustone. It is manufactured or secreted in a specific section of the alimentary canal, i.e. the crop. Reception is not through the antennae but through the stigmata. Preliminary chemical analysis of a risella oil air extract distilled into various other solvents showed the presence of a relatively simple saturated aliphatic chain with a carbonyl function, perhaps a ketone or an ester.

    Notes: Summary We have used a full length cDNA clone to determine the chromosomal location ofthegene encoding human ornithine aminotransferase (OAT), a mitochondrial matrix enzyme. Southern blot analysis of ScaI-digested DNA from 34 human-mouse somatic cell hybrids revealed 11 human fragments. Three fragments mapped to chromosome 10q23-10qter, confirming the previous provisional assignment of the functional gene to this autosome by analysis of OAT expression in somatic cell hybrids (O'Donnell et al. 1985). The remaining eight fragments were assigned to the X chromosome, and regionally assigned to Xp21-Xp11 by use of an X-chromosome mapping panel. These X chromosome sequences could represent pseudogenes, or related members of a multigene family. Two of the X chromosome fragments are alternate alleles of a restriction fragment length polymorphism (RFLP) making this OAT-related locus an excellent genetic marker. The RFLP may now be used to determine any possible relationship between this locus and several X-linked eye defects.
