    Notes: Abstract By means of a level crossing experiment the hyperfine structure constants of thez 6 P 7/2-level of Eu have been determined. The results areA=-6.51(6) MHz andB= 131.2(1.0) MHz in the isotope151Eu andA=-2.84(3) MHz andB=327.5(1.5) MHz in the isotope153Eu. Experimental data on the hyperfine splitting are available now for 11 of the 12 levels of the configuration 4f 7 (8S)6s 6p of EuI. These data are compared with the theoretical interpretation given by Bordarieret al. [1] which was based on only 7A-factors andB-factors. It is shown that the agreement between theory and experiment can be improved by taking into account configuration interactions.

    Schnellere Zentrifugen ins Laboratorium! (1940)

    Notes: Zusammenfassung An Hand theoretischer Übeilegungen und vergleichender Versuche mit verschiedenen Bakterien wird gezeigt, daß diese und auch Teilchen ähnlicher Gößenordnung unter sonst gleichen Bedingungen durch steigende Umdrehungszahlen aus der Suspensionsflüssigkeit sehr viel leichter und vollständiger ausgeschleudert werden können. Der Erfolg war in etwas wechselndem Maße stets besser, einmal sogar um das 4000 fache günstiger. Im Hinblick auf die Bedeutung dieser Tatsache, namentlich für diagnostische Untersuchungen, wird die Forderung erhoben, in allen fortschrittlichen Laboratorien die veralteten Modelle durch schnellere Zentrifugen zu ersetzen, zumal da diese kaum teurer sind. Besondere Sorgfalt ist jedoch nötig. Der Nachweis von Tuberkelbacillen wird auf dem genannten Wege ganz erheblich verbessert.

    Gasödem der Brusthöhle (1944)

    Notes: Zusammenfassung Gasödem außerhalb der Muskulatur in den Organen des Körpers ist sehr selten, an den Baucheinge-weiden, abgesehen von der Gallenblase, überhaupt nicht beobachtet. Gasbrandbacillen vom Typ Welch-Fraenkel wurden öfter als einzige Keime im Pleuraexsudat nach Verletzungen oder Punktionen nachgewiesen. Sie können — wie im mitgeteilten Falle — auch in den Lungen pathogen wirken, also Gasödem der Brusthöhle verursachen mit langsamem Krankheitsverlauf. Die Röntgendiagnostik des Gasödems wird kurz gewürdigt und eine Aufnahme veröffentlicht, die als Befund nach Splitterverletzungen der Brust schwierig zu deuten war.

    Verbesserter Tuberkelbacillennachweis Durch Schnellere Zentrifugen (1941)

    Notes: Zusammenfassung Die Ergebnisse beim Ausschleudern von Tuberkelbacillensuspensionen werden durch die Verwendungschneller Zentrifugen erheblich verbessert. Mit Reinkulturen ließ sich eine etwa 100 fache Überlegenheit über die Leistung einer gewöhnlichen Laboratoriumszentrifuge nachweisen. In ähnlichem Grade dürften die Erfolge bei der Anreicherung zur mikroskopischen Untersuchung, auch verbunden mit der Fluorescenzmikroskopie, zur Kultur, zum Tierversuch usw. gesteigert werden können. An Hand der Befunde bei einem Kranken der Klinik wird der Fortschritt bewiesen.

    Comparative studies on the pre-and postterminal blood vessels in the cerebellar cortex of rhesus monkey, cat, and rat (1979)

    Notes: Summary In the rhesus monkey, cat and rat, pial arteries give off branches which run vertically through all three layers of the cerebellar cortex. The large cortical arteries are surrounded by a perivascular space in the molecular layer. Their wall consists of several layers of smooth-muscle cells and the luminal endothelium. As the arteries reach the deeper layers of the cerebellar cortex, the number of smooth-muscle cells is reduced. In the rat, sometimes no smooth-muscle cells are detectable in the preterminal arterial vessels. If these deep arteries branch off by dichotomy of terminal vessels there occurs a gradual or complete loss of myocytes in all three species. In the cat, where cortical arteries give off branches at rightangles, there is a sphincter-like accumulation of smooth-muscle cells at the opening to the smaller branch. The postterminal vessels and veins in all species exhibit the smae mural structure found in capillaries. The wall consists only of an endothelium and occasional pericytes embedded in the basal lamina. Even the large veins which run to the pial veins show this simple mural structure.

    Notes: Summary In the spinal cord of the rhesus monkey and of the cat paired vessels near the central canal are described. These paired vessels, consisting of one artery and one vein, are enveloped by a common glial sheath. In some Virchow-Robin's spaces two arteries and two veins can be observed. The physiological significance of this morphological feature is briefly discussed.

    Notes: Abstract We first show how to formalize environments in which situations can be changed only by action, and in which a situation should be brought about that is acceptable. This leads us to the concept of a problem constellation that consists of an action system, a reaction system, a judgement system, and an initial situation. We then present a cybernetical system which we call Robbimat. It is capable of testing problem constellations, of modifying them according to the results of the tests, and of judging the final constellation. We designed Robbimat in order to have favourable problem constellations automatically generated. As an example we discuss a simple game. It constitutes a win-loss-environment the structure of which can be deduced from the payoff function. We show how Robbimat analyses such an environment, and utilizing its structure classifies the initial situation.
