    Description / Table of Contents: Summary The deflection of a plane turbulent jet in a crossflow is described by a model which takes the effects of entrainment as well as those of crossflow pressure into account. Using this model the centerline and the spread of the jet and the mean velocity averaged over its cross-section can be calculated. Asymptotic analytic solutions are given for the case where the velocity of the unperturbed crossflow is much smaller than that of the unperturbed jet. A comparison of the present calculations with experimental results of other authors shows good agreement.
    Notes: Übersicht Zur Beschreibung der Umlenkung eines ebenen turbulenten Freistrahles durch eine Querströmuug wird ein Modell entwickelt, bei dem sowohl die Einsaugwirkung des Strahles als auch die Druckwirkung der Querströmung auf den Strahl berücksichtigt werden. Hiermit können die Strahlmittellinie, die Strahlbreite und die über einen Strahlquerschnitt gemittelte Geschwindigkeit berechnet werden. Es werden analytische Näherungslösungen für die Fälle angegeben, in denen die Geschwindigkeit der ungestörten Querströmung wesentlich kleiner als diejenige des ungestörten Strahles ist. Ein Vergleich der berechneten Größen mit experimentellen Ergebnissen anderer Autoren zeigt gute Übereinstimmung.

    Notes: Abstract Thin sections in the thickness range down to 3–5 μm were produced from bariumtitanate ferroelectric ceramics. The small signal dielectric constant, as well as hysteresis loops were measured. Significant deviations from the bulk properties were observed, when the thickness of the sample was decreased to the average diameter of the grains. The measured results are discussed proposing a model with internal stresses and a distorted surface layer.

    Description / Table of Contents: Zusammenfassung Es wird über einen zwölfjährigen Jungen berichtet, der an einer akuten basalen Subarachnoidalblutung nach einer tätlichen Auseinandersetzung — von Augenzeugen nur als Rangelei bezeichnet — mit einem Klassenkameraden verstarb. Als Blutungsquelle wird eine Gefäßruptur im System der Vena cerebri magna Galeni und der Vv. cerebri parvae (internae) auf dem Boden einer möglichen mikrodysontogenetischen Vorschädigung der Gefäße diskutiert.
    Notes: Summary Report of the case of a 12-year-old boy who had died due to massive basal subarachnoid hemorrhage after moderate fight with a class mate. Findings at autopsy and by microscopic examination indicated that a lesion in the system of the great vein of Galen and the internal cerebral veins might have been the source of the bleeding. The nature of an underlying pre-existing vascular change favoring a rupture is discussed on the basis of the clinical history and the pathoanatomic findings.

    Notes: Abstract Using the nonmagnetic BONANZA detector for the detection of antineutrons and antiprotons, we measured branching ratios of theJ/ψ into baryonic final states. Our measurements give the new results: $$BR\left( {{J \mathord{\left/ {\vphantom {J {\psi \to \overline {\Sigma ^ - } }}} \right. \kern-\nulldelimiterspace} {\psi \to \overline {\Sigma ^ - } }}\Sigma ^ - } \right) = \left( {0.24 \pm 0.26} \right)\% ;BR\left( {{J \mathord{\left/ {\vphantom {J {\psi \to }}} \right. \kern-\nulldelimiterspace} {\psi \to }}\bar nn\pi ^ + \pi ^ - } \right) = \left( {0.38 \pm 0.36} \right)\% $$ and an independent test for the data of the magnetic detectors.
