    The production of charginos of theSU(N, 1) minimal sugra model ine + e − annihilation andp $$\bar p$$ collider experiments (1987)
    Springer
    The European physical journal 36 (1987), S. 715-723

    Notes: Abstract We present cross sections for the charged lepton production from the lightest charged superpartner particles predicted by theSU(N, 1) Minimal SUGRA model, either the superpartners of the r.h. charged leptons or the Wino/Higgsino. At least one of these should appear in the decay of theZ, which is produced ine + e −-annihilation-presumably soon at the SLC — or inp $$\bar p$$ collider experiments. A large missing mass and strong deviations from back to back production of lepton pairs (and possibly ae-μ final state) would indicate such charged massive intermediate particles.

    The neutralinos of theSU(N,1) minimal supergravity model and standard cosmology (1988)
    Springer
    The European physical journal 40 (1988), S. 591-598 
    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We discuss the effect of the lightest supersymmetric particle (LSP), a Higgsino, and of the gravitino of theSU(N,1) minimal SUGRA model in the standard big bang theory. The freeze out of the LSP depends on the gravitino mass and on the top mass and leads to restrictive lower bounds for these parameters in the model. The decay of a gravitino with mass in the few TeV range leads to a delay in the cooling of the universe before nucleosynthesis. This constitutes the main bound on the gravitino mass of the model. The results are compared with the more standard “simultaneous decay approximation”.

    Hf-sputtered indium oxide films doped with tin (1978)
    Springer
    Applied physics 16 (1978), S. 239-246

    Notes: Abstract Indium oxide films doped with tin (ITO-films) have been hf-sputtered from an 80 at-%In2O3/20 at-%SnO2 target onto glass substrates. The sputter atmosphere contained mainly argon (10−2Torr) with addition of oxygen (0≦p O 2≦2·10−2Torr). The sputtered films aren-conductors. The conductivity and density of charge carriers depend on the oxygen content of the sputter gas. They could be varied by two orders of magnitude. In air or in oxygen atmosphere the films oxidize at the surface and for a certain depth beneath the surface, thus decreasing the conductivity. The Hall mobility of the sputtered films is smaller (≈10 cm2V−1 s−1) than one observes at ITO films produced by CVD sparaying or other methods. The conductivity of as sputtered films approached maximum values of about 1000Ώ−1cm−1.

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

    ISSN: 1432-1114
    Source: Springer Online Journal Archives 1860-2000
    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.

    Description / Table of Contents: Zusammenfassung Für die Kompressionsgleichung (s − a) (p + b) = C wurden die drei Hyperbelkonstanten a, b, und C interpretiert und ihre Abhängigkeit vom Mischungsverhältnis zweier Substanzen untersucht. Die Grö\e b wurde als Verformungsspannung bezeichnet, sie kann mit der Flie\grenze eines Materials in Beziehung gesetzt werden. In einer Tablettenrezeptur kann der Anteil an verformtem Arzneistoff mit Hilfe der Konstanten b abgeschätzt werden.
    Notes: Abstract The three hyperbolic constants a, b and C were interpreted for the compression equation (s − a) (p + b) = C. Their dependence upon the mixture ratio of two substances was investigated. The quantity b was designated as deformation strain, it can be related to the yield point of a material. The proportion of deformed drug in a tablet formulation can be estimated by means of the constant b.
