    Electron density studies of KCl and LiF by γ-ray diffractometry (1985)
    [S.l.] : International Union of Crystallography (IUCr)

    Notes: Use of hard electromagnetic radiation (λ = 0.12 Å) in diffraction experiments, in conjunction with thin crystals in transmission geometry (Laue case), minimizes multiple scattering, often referred to as the 'extinction problem'. A large crystal slab, completely intercepting the incident beam, was used in this experiment. Several structure factors have been measured in LiF and KCl, with greater accuracy than ever before, using the γ-ray spectrometer of the University of Missouri at Columbia. In the case of LiF the results indicates some compression of the valence electron densities, similar to what has been found earlier for NaF. In the case of KCl all reflections agree well with the values calculated from free-atom Hartree-Fock wave functions except for the 004 and 006, which are appreciably weaker than corresponding reflections with similar or identical sin θ/λ values. This result indicates asphericity of the valence electron density. The 111 is also much weaker than the calculated value, indicating that the negative ions are slightly compressed and the positive ions slightly expanded with respect to the free-ion charge densities.

    Alignment and application of the conical shadowgraph flow visualization technique (1986)
    Springer
    Experiments in fluids 4 (1986), S. 93-96

    ISSN: 1432-1114

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract An optical bench study has been carried out to assess the effects of both beam alignment and nonconical disturbances in the application of conical shadowgraphy for flow visualization. Conical and quasiconical plastic test models were immersed in a refractive index matching fluid and then examined by shadowgraphy with a conical light beam. The results show that problems of interpretation may arise due to both axial and transverse beam misalignment. Among these difficulties, axial misalignment with positive vertex displacement is the least serious. Also, the effect of a particular nonconical disturbance field was found to introduce fewer difficulties of interpretation than that of beam misalignment.

    Laborversuche über Auswirkungen staubförmiger Kalkdünger auf die Kahlrückige Waldameise,Formica polyctena Först. (Hym., Formicidae) (1986)

    Description / Table of Contents: Zusammenfassung 1984 und 1985 wurden in Laborversuchen bei insgesamt 24 Kleinpopulationen (je 2000 ♀♀ u. 2 ♂♂) vonFormica polyctena die Auswirkungen handelsüblicher staubförmiger Kalkdünger auf Mortalität, Anzahl des Nachwuchses und Beuteeintrag untersucht. Bei Bestäuben der Versuchsvölker und ihres Lebensraumes wurden in allen Fällen Beeinträchtigungen sämtlicher untersuchtet Parameter festgestellt. Dabei waren deutliche Unterschiede im Ausmaß der Schädigung je nach Feinkörnigkeit der verwendeten Mittel zu beobachten. Der 2. Versuch (1985) zeigte, daß die chemische Zusammensetzung der Düngestäube keine entscheidende Rolle spielte. Bei ausschließlich oraler Applikation der Mittel wurden keine Unterschiede zu unbehandelten Kontrollvölkern festgestellt.
    Notes: Abstract Calcium fertilizers as a dust were tested under laboratory conditions on their effects on small populations (2000 ♀♀, 2 ♂♂) of the Red Hillbuilding Wood AntFormica polyctena. Mixed into the food, the ants didn't show any reactions; however dusted with Calcium, daily mortality increased up to 10 times compared to non treated populations. Furthermore, reproduction and foraging activity were diminished. Additional experiments using one brand of fertilizer but different particle sizes showed that the finer the dust, the more detrimental is Calcium fertilizer to laboratory populations ofF. polyctena.

    Description / Table of Contents: Zusammenfassung Zwei Laborpopulationen vonFormica polyctena (mit je 2000–3000 Arbeiterinnen und 2 Königinnen) wurden Raupen vonOrgyia antiqua als Nahrung vorgesetzt. Die L1 bis L3 wurden von den Ameisen nicht als Beute erkannt. Von den L4 bis L6 wurden von Population A=49% und von Population B =77% durch Verzehr oder Verletzung vernichtet. Um die lang behaarten Raupen töten zu können, „rupften” ihnen die Ameisen zuvor die Haare.
    Notes: Abstract O. antiqua larvae were given as food to two laboratory populations ofF. polyctena (2000–3000 workers and 2 queens each). The ants did'nt perceive L1–L3 as a prey. But they killed 47% (popul. A) and 77% (popul. B) of the L4–L6 after pulling up the long hairs of larvae.

    Dynamics of a subconstituent picture of weak interactions (1985)
    Springer
    The European physical journal 26 (1985), S. 569-580 
    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We use sum rules in order to discuss the dynamics of the simplest subconstituent model of weak interactions with elementary spin 1/2 fermions and scalar bosons. Vacuum condensates of the scalars play an essential role and lead to features quite different from QCD. With a certain vacuum structure vector dominance of the composite W-mesons is a good approximation, and we also see a clear signal for massless fermions in the two-point function of composite fermions. Thus such a model is in good agreement with standard phenomenology. Composite Higgs particles are also investigated. The effective interaction is evidently of the gauge type.

    Instanton induced green functions in the superfield formalism (1986)
    Springer
    The European physical journal 30 (1986), S. 161-174 
    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We discuss in detail the supersymmetric instanton calculus of NSVZ and extend it to chiral matter fields in the, adjoint representation. The constant Green functions induced by the instanton of supersymmetricSU (2) gauge theories are calculated systematically for the cases with and without scalar vev's bigger than the scale of the gauge theory and for nonvanishing small masses of chiral fields. Oneinstanton contributions to the Green functions containing four fields without large vevs would disturb clustering; but they are argued to vanish; two-instanton effects then lead to a pattern which quantitatively agrees with factorization and the anomaly relation.
