    Description / Table of Contents: Zusammenfassung Im Vergleich zu handelsüblichen Mikrospateln bietet die Verwendung von besonders geformter Meßspateln für die Dosierung reproduzierbarer Mengen verschiedener Substanzen keine Vorteile.
    Abstract: Résumé La comparaison des possibilités de deux spatules, de forme différente de celle de la spatule semimicro conventionnelle pour la mesure des prises d'essai, montre que l'emploi de procédés plus complexes, pour l'obtention de quantités reproductibles, ne présente pas d'avantages.
    Notes: Summary The performance of two forms of measuring spatulae as compared with that of a conventional semimicro spatula show that for obtaining reproducible amounts of various substances there is no advantage to be gained in using the more complex procedures.

    A non-destructive field assay for soybean nitrogen fixation by acetylene reduction (1983)
    Springer
    Plant and soil 70 (1983), S. 173-182 
    Details
    ISSN: 1573-5036
    Keywords: Acetylene reduction ; Glycine max L. ; Nitrogen fixation ; Soybean

    Notes: Summary A system for employing open-ended root chambers to measurein situ acetylene reduction rates under field conditions is described. Gas mixtures containing about 2 mbar acetylene were continuously flowed through the chambers providing a continuous record of acetylene reduction. These chambers have been used to measure acetylene reduction rates of soybeans during three growing seasons. The system has proved to be reliable with a high degree of precision. The large amount of plant-to-plant variability observed in N2 fixation research has been confirmed by the data collected with this system. However, such variability in physiological studies can be reduced by using a non-destructive system to compare the response of an individual plant with its rates before treatment.

    DTA and TGA studies of flame-resistant fabrics (1966)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 10 (1966), S. 1041-1066

    Notes: Preliminary thermal studies were made of cotton fabrics which had been made flame resistant by chemical modification or by blending with a flame-resistant modified acrylic fiber. DTA and TGA thermograms were made in both nitrogen and oxygen atmospheres. Differences were found in the thermograms of the untreated controls, depending upon amount of purification. Fabrics treated with the flame-retardant formulations had lower decomposition temperatures and higher percent residue. Decomposition in oxygen was more complete and proceeded at a lower temperature. Infrared spectra of selected samples, which had been partially or completely charred, were examined. These data are related to theories about the degradation of flame-resistant cotton fabrics.

    Hyperfine structure of the 33 P state of3He and isotope shift for the 23 S-33 P 0 transition (1995)

    Notes: Abstract The hyperfine structure of the3He 1s 3p 3 P state and the3He-4He isotope shift is determined by high precision measurements of the 1s2s 3 S 1-1s 3p 3 p 3 P J transition frequencies near 389 nm. A direct frequency measurement is made without the need for wavelength calibration by tuning a single laser to the atomic frequency, and using a novel heterodyne method to observe beat frequencies with a stable reference laser. A fit to a theoretical model of hyperfine structure is used to determine the hyperfine shifts. Additional off-diagonal mixing effects are investigated to resolve a possible systematic discrepancy in the hyperfine intervals. The final isotope shift without hyperfine structure of 42184308±165 kHz is used to deduce an rms nuclear charge radius for3He of 1.956±0.042 fm. This is in good agreement with other values obtained from atomic isotope shift measurements, and a recent theoretical value of 1.958±0.006 fm. The present result helps to resolve substantial differences in the3He nuclear radius derived from electron-nuclear scattering measurements, and it provides a significant test of the nuclear three-body problem.
