    Notes: Schluss Zusammenfassend kann man also als Ergebnis der Untersuchungen folgendes aufstellen: 1. Eine günstige Einwirkung einer Behandlung mit Alttuberkulin, in der Weise wie sie etwa in der Humanmedizin angewendet wird, konnte ich bei der Impftuberkulose des Meerschweinchens ebensowenig wie Haupt und frühere Untersucher beobachten, weder was die Lebensdauer noch was die klinischen und anatomischen Veränderungen betrifft. 2. Behandlung mit ziemlich grossen Dosen Rosenbachschen Tuberkulins scheint in solchen Fällen, die schon an sich zu sehr chronischem Verlauf neigen, noch eine weitere Verlangsamung des Krank heitsablaufes herbeiführen zu können, also immerhin günstig, wenn auch nicht heilend wirken zu können. 3. Beide Mittel werden von den Tieren in grossen Mengen vertragen. Eine immunisierende Wirkung haben beide nicht. Selbstverständlich berechtigt dieses Ergebnis keineswegs dazu, etwa bei der menschlichen Tuberkulose die Versuche mit dem Rosenbachschen Präparat aufzugeben, ebenso wie man ja das Alttuberkulin trotz seiner Unwirksamkeit gegen die Meerschweinchen tuberkulose in der Humanmedizin mit Nutzen verwendet.

    Interpretation of the shape of electron diffraction spots from small polyhedral crystals by means of the crystal shape amplitude (1988)

    Notes: The influence of the crystal shape on the fine structure of transmission electron diffraction (TED) patterns described by the crystal shape amplitude is discussed. A general algebraic expression for the crystal shape amplitude of any crystal polyhedron is used for computing the intensity distribution of TED reflections. The computer simulation method is applied to the analysis of the fine structure of TED patterns of small gold and palladium crystals having octahedral and tetrahedral habits.

    Magnetische Hysteresis bei hoher Frequenz (1928)

    Notes: Zusammenfassung Zwei Eisensorten, schwedischer Bandstahl und 50%ige Fe-Ni-Legierung der Fr. Krupp-A. G. wurden wechselnder Magnetisierung bei Frequenzen von etwa 500, 1500 und 2550 Hertz unterworfen und die Hysteresiskurven punktweise auf-genommen. Eine Vergleichung mit den statischen Kurven bei gleicher maximaler Magnetisierung ergab ein mit wachsender Frequenz zunehmendes Zurückbleiben der Magnetisierung hinter den statischen Werten. Die Vergrößerung der Hysteresis-verluste betrug für den Bandstahl etwa 3% bei 500 und 8 bis 9% bei 2550 Hertz, für die Fe-Ni-Legierung etwa 20% bei 500 und 60% bei 1500 Hertz. In roher Annäherung ist für eine gegebene Eisensorte scheinbare Vergrößerung der Koerzitivkraft proportional der maximalen Magnetisierungsgeschwindigkeit ∂B/∂t, unabhägig von der Feldamplitude und der Frequenz.

    Effect of ribbon-wheel contact on the microstructure of melt-spun Al-Cu eutectic alloy ribbons (1985)

    Notes: Abstract The microstructure of melt-spun Al-17.3 at% Cu eutectic alloy ribbons with different thicknesses have been revealed by means of electron microscopy and X-ray techniques. Thick ribbons (〉20μm) consist of finely-dispersed α-Al and Al2Cu equilibrium phases showing lamellar or irregular morphology. In thin ribbons a considerable fraction of supersaturated α-Al solid solution and the metastable Al4Cu9 phase have been detected. The experimental facts on the identity of the phases, their morphology and particle size for given processing conditions are discussed within the framework of a heat flow model including the solidification process as well as post-solidification transformations. The microstructural features are considered to be determined by local and time variations of the ribbon-wheel contact.

    Entwicklung eines Analysenverfahrens für Rutheniumspuren in Pflanzenmaterial und Ermittlung der Transferfaktoren Boden/Pflanzen für Rutheniumverbindungen aus Wiederaufarbeitungsanlagen (1988)

    Notes: Summary Considerably different transfer factors soil/plant are reported in literature for the fission product ruthenium. As ruthenium belongs to those radioactive nuclides, that could be released from a reprocessing plant during an accident, reliable transfer factors should be explored under middle-European conditions for some typical nutrition plants. In an artificial humous and sandy soil spiked with 106Ru as RuO2 and RuCl3, pasture grass was grown under artificial illumination in our laboratory. The amounts of ruthenium taken up by the plants were determined by γ-spectrometry. For open-air investigations with pasture grass, wheat and potatoes inactive ruthenium(III) chloride and ruthenium nitrosylchloride were used. Ruthenium was determined by electrothermal atomic absorption spectrometry (ETAAS) after destroying the organic material and concentrating the solution. The concentration and chemical form of the ruthenium exert an unimportant influence on the transfer factor. For the pasture-grass, the stems of wheat and the weed of potatoes it amounts to 0.00005 to 0.0015, for the ear of wheat to about 0.00005. In peeled potatoes there was no ruthenium detectable, therefore the limit of detection leads to a transfer factor ≤0.00001. So it is evident that ruthenium is little available for the roots of the plants. In the event of an accident in a nuclear plant the uptake of radioactive ruthenium by roots has only negligible radioecological consequences. This applies even if 50 years of ruthenium enrichment in the soil are assumed.
