    Description / Table of Contents: Zusammenfassung Es wird das grenzflächendynamische Verhalten eines fluiden Zweiphasensystems unter den Bedingungen einer gezielten örtlichen Beaufschlagung der Phasengrenze durch ebene Strahlen bei gleichzeitig ablaufendem Stoffübergang untersucht. Hierzu wird in einem ausgewählten Punkt die Tangentialgeschwindigkeit in der Phasengrenze bzw. in Phasengrenznähe in Abhängigkeit von der Austrittsgeschwindigkeit der Strahlen in den beiden Phasen berührungslos mit Hilfe einer Laser-Doppler-Velocimeter-Anordnung im System Luft-Wasser mit und ohne Übergang von Azeton vermessen und verglichen. Die nur bei niedrigen Strahlaustrittsgeschwindigkeiten nachweisbaren Änderungen der Strömungsgeschwindigkeiten durch grenzflächendynamische Effekte werden an Hand von Modellvorstellungen diskutiert und mit theoretischen Untersuchungen des Wärmeüberganges in einem fluiden Zweiphasensystem verglichen.
    Notes: Abstract The interfacial-dynamic behaviour of a fluid two-phase-system with mass transfer was investigated under influence of forced convection in the manner of flat jets directed to the interface. The tangential velocities were measured at a characteristic point near to the interface air/water or in the interface itself using a Laser-Doppler-Velocimeter in dependence on the velocities of jets into two phases in both cases with and without transfer of acetone. The variations of velocities due to the interfacial effects are only detectable at small velocities of the jets. They are discussed by model conceptions and compared with the results of a theoretical research of heat transfer in a fluid two-phase-system (Interfacial-dynamic surface renewal model).

    Description / Table of Contents: Zusammenfassung Ein 3jähriger Junge entwickelte ohne ersichtlichen spezifischen Grund einen Schiefhals. Obwohl unmittelbar nach Auftreten der Symptome eine Behandlung begonnen wurde, konnte keine Besserung erzielt werden. 4 Monate später angefertigte Röntgenbilder zeigten eine Vergrößßerung des Abstandes zwischen Dens und Atlas. Trotz dieses Befundes wurde der Patient mit Tenotomie und intensiver Physiotherapie behandelt, der Schiefhals aber blieb bestehen. 2 Jahre später deckten ein Tomogramm and ein Computertomogramm eine komplette, rotationsbedingte Verrenkung zwischen Atlas und Axis auf. In diesem Stadium war eine ursächliche Behandlung nicht mehr möglich. Es konnte nur die physiotherapeutische Behandlung fortgesetzt werden mit dem Ziel, die Kopfstellung zu verbessern.
    Notes: Summary Without any known specific cause a 3-year-old boy developed a torticollis. Although the symptoms were treated immediately there was no improvement. Four months later X-rays showed that the dens-atlas distance was enlarged. In spite of this, he was treated by tenotomy and intensive physiotherapy, but the torticollis remained. Two years later a tomogram and a CT showed a complete rotatory dislocation between atlas and axis. At this stage it was impossible to treat the original cause. Physiotherapy was continued to improve the position of the head.

    Description / Table of Contents: Zusammenfassung Durch „reversed phase”-Chromatographie von 3H- oder 14C-serinbeladenen Gesamt-tRNA-Präparaten wurde das Multiplizitätsmuster der serinspezifischen Transfer-Ribonucleinsäuren in der Meerschweinchenepidermis ermittelt und mit dem der Leber als Bezugssystem verglichen. Fünf tRNAser (I–V) konnten dargestellt werden, von denen zwei, tRNA I ser und tRNA V ser , „typisch” für die Epidermis zu sein scheinen und insofern möglicherweise Stoffwechselbesonderheiten der epidermalen Zelldifferenzierung reflektieren. Diese Hypothese wurde weiter untermauert, indem gezeigt werden konnte, daß lokale Applikation des Corticosteroids Triamcinolon in der Meerschweinchenepidermis selektiv tRNA I ser und tRNA V ser auf das Zwei- bis Dreifache erhöht. Die mögliche Bedeutung dieser Befunde wurde eingehend diskutiert.
    Notes: Summary The pattern of serine-specific tRNAs from guinea pig epidermis was determined and compared to that from liver by employing reversed phase chromatography on total tRNA preparations aminoacylated with 3H- or 14C-serine. Five tRNA s ser (I–V) were found, two of which, tRNA I ser and tRNA V ser , appear to be “typical” for epidermis and in so far probably reflect in some way metabolic pecularities of epidermal cell differentiation. This hypothesis was further corroborated by showing that the locally applied corticosteroid triamcinolon selectively increases tRNA I ser and tRNA V ser 2-3-fold. The implications of these findings were discussed in detail.

    Notes: Abstract We studied the region of giant resonances with positive pions of 226 MeV scattered inelastically on90Zr. Two groups of resonances were seen: the first structure between 12 and 19 MeV excitation energy is explained as a sum of the isoscalar quadrupole resonance at 14 MeV, the isovector dipole resonance at 16.5 MeV and possibly some E0 strength. The second group between 24 and 34 MeV excitation energy also corresponds to more than a simple multipolarity and may be described as a sum of a monopole and a quadrupole isovector resonance.
