    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.

    Simultaneous vertical profiles of condensation nuclei and ozone in the lower troposphere (1974)
    Springer
    Pure and applied geophysics 112 (1974), S. 887-899 
    Details
    ISSN: 1420-9136

    Notes: Summary Eight vertical profiles compiled from simultaneous measurements of Aitken nuclei and ozone concentrations over Germany in different weather conditions are discussed. The position and shape of the profiles is shown to depend on the prevailing weather conditions and the type of air masses. High aerosol concentrations in smoke plumes correlate in some cases with lower ozone concentrations, indicating that ozone in such cases is destroyed in the presence of high concentrations of pollutants such as aerosols and gases. A layered structure in the profiles was found only in association with temperature inversions and where the air above 2 km was subsiding, and was not found in convective parts of the troposphere.

    Über Versuche zur Fütterung der Kahlrückigen Waldameise (Formica polyctena F.; Hym., Formicidae) mit den behaarten Raupen vonOrgyia antiqua L. (Lep., Lymantriidae) (1985)

    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

    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.

    A grand unified theory based onSU(n, 1)-minimal supergravity (1985)
    Springer
    The European physical journal 29 (1985), S. 209-217 
    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We discuss a grand unified theory in the framework ofSU(n, 1) minimal supergravity with the Planck mass as the only input mass scale.M W ≈m 3/2 is fixed by radiative corrections to be naturally ≪M P1. Due to the particular form of explicit soft supersymmetry breaking a light singlet can be used to obtain naturally light Higgs doublets and for a new mechanism for radiativeSU (2)×U(1) breaking. The low energy particle spectrum is very restricted withm 3/2≈104 GeV.

    Notes: The big success of the reaction injection molding (RIM) process has brought about a marked interest in reacting polymer processing. In the present work, we study the technical feasibility of a continuous process to coat metallic conductors using reacting polymers. In the envisioned system, RIM type reactants are mixed and then injected into a tubular reactor through the center of which we pass the cable to be coated. The predictions of the mathematical model developed show that a feasible process can be designed by adequate control of the heat transfer phenomena. The process needs in general, a low reactor temperature and a high cable temperature.
