    Notes: The relationship between hydrodynamics and radiative energy loss from a gas puff Z pinch was studied using helium, krypton, and a helium–krypton mixture. The results show that radiation cooling enables the magnetic field to compress the plasma to a higher electron density and a smaller final radius. The data are consistent with a simple model describing the thermalization of the plasma on the axis of the pinch. The spectrum of the krypton radiation from the mixture was harder than from the pure krypton pinch. This may be important for application of the Z pinch as a radiation source.

    Notes: Pin plasma sources are used as x-ray backlights for an Al plasma produced by focusing 1.06-μm laser light to irradiances of 1012 W/cm−2. Spatially resolved absorption features of the helium- like states of ionization of the plasma allow ground-state densities of the helium and hydrogenlike stages to be measured. Comparison with simulations indicates the need for realistic opacity effects to produce a high enough state of ionization for the plasma temperature. Work performed under the auspices of the U.S. DOE by the Lawrence Livermore National Laboratory under Contract No. W-7405-ENG-48.

    Notes: We report on the construction and testing of a 100-ps framing camera based on a gated microchannel plate. The gating is obtained by applying a fast voltage pulse directly across the microchannel plate detector. An infinite ground-plane microstrip transmission-line configuration is used. We have measured the transit time for electrons through the microchannel plate to be 150±35 ps and the rise and fall times of the detector to be less than 100 ps. The time resolution computed using the experimentally measured edge response times is less than 100 ps.

    Notes: The enteric pathogen screen (EPS) card designed for use with the Vitek Auto Microbic System (AMS) was evaluated with stock cultures and fresh isolates from ground beef, pork sausage, chicken and turkey to determine its effectiveness as a screen for Salmonella, Yersinia enterocolitica and Shigella. Each isolate was concurrently tested with the Micro-ID test strip and the AMS Gram negative identification card to confirm its identification. The EPS accurately classified 115 of 125 (92%) of the stock cultures and 207 of 212 (97%) of the fresh food isolates. The EPS gives a rapid presumptive screen at a relatively low cost and as such is a viable alternative to conventional procedures.

    Notes: [Auszug] Polarimetry and photometry of NGC5128 in the J(1.20 ??), H(1.64 ??) and ? (2.19 ??) bands were obtained on 26 June 1985. Polarimetry in the L' band (3.8 ??) was obtained on 2 and 3 July 1985. All observations were made using the 3.9-m Anglo-Australian telescope and the Hatfield polarimeter2. The ...

    Notes: Abstract Environmental factors more common in twins than singletons appear to be disadvantageous with respect to intelligence. If these factors contribute to within-pair differences in IQ, the effect should be found more in the cotwin lower in IQ (the low twin) than in the cotwin higher in IQ (the high twin). In this case, the variance of the low twins should exceed that of the high twins. This hypothesis was tested for five samples of monozygotic (MZ) twins and three samples of dizygotic (DZ) twins but was confirmed only for the MZ samples. These results suggest that there are disadvantageous environmental factors unique to MZ twins which contribute to within-pair variability. Such factors will cause heritability coefficients obtained using MZ twins to be underestimated.

    Notes: Abstract A 6,9-nonadecadiene, (Z)-9-nonadecene, andn-nonadecane were identified in extracts of sex pheromone glands of femaleSabulodes caberata Guenée. Potential pheromonal activity of gland components was assessed by electroantennogram measurements of gas-chromatographic fractions of abdominal tip extracts. Chemical identification was based on gas chromatography and mass spectrometry of parent compounds, hydrogenation products, ozonolysis products, dimethyl disulfide adducts, and synthesis. The monoene was synthesized via coupling of alkyl and acetylenic intermediates. (Z,Z)-6,9-Nonadecadiene (Z6,Z9-19∶H) was synthesized from methyl linoleate via chain lengthening. SyntheticZ6,Z9-19∶H had the same retention times on polar and nonpolar capillary gas-chromatographic columns as the 6,9-nonadecadiene from the sex pheromone glands. In field testsZ6,Z9-19:H alone produced trap catch of maleS. caberata and addition of (Z)-9-nonadecene orn-nonadecane had no effect on trap catch.

    Notes: Abstract The most effective lure for maleAmorbia cuneana (Walsingham) in Orange, Ventura, and Riverside counties of California was previously found to be a 1∶1 ratio of (E,E)-10,12- and (E,Z)-10,12-tetradecadien-1-ol acetates. In subsequent field tests in San Diego and Santa Barbara counties, this lure was ineffective. Analysis of sex pheromone glands (SPG) of femaleA. cuneana from these two counties showed theEE:EZ ratio to be about 1∶9 and synthetic lures of this composition were highly attractive in these areas. Analysis of the SPG of a number of females from both areas showed that there were three population types: two in the low ratio areas possessed 37 and 58%EZ, and the third in the high ratio areas possessed 89%EZ.
