    Notes: Summary The pharmacokinetics of theophylline (200 mg i.v.) were determined in 20 geriatric patients with multiple diseases. Serum concentrations were fitted to an open 2-compartment model. Percent changes in venous pCO2 and pO2 were used as parameters of the pharmacodynamic action. Total clearance was decreased and elimination half-life of theophylline was found to be prolonged in the elderly patients compared with data of a study with young healthy volunteers. The stronger the pharmacodynamic action of theophylline (percent change of venous pCO2 after 30 min), the faster was its elimination and the lower were measured concentrations after 2, 6, and 12 h.

    Notes: Zusammenfassung Die Häufigkeit lokaler Rezidive nach organerhaltender Behandlung des Mammakarzinoms war in unserem Kollektiv mit 3,8% gering bei einer mittleren Beobachtungszeit von 45 Monaten. Die Diagnostik des Lokalrezidives ist durch postoperative und radiatiobedingte Narbenfibrosen und Fibrosen sowie Verkalkungsstrukturen im Mammogramm erheblich erschwert. Hilfreich ist sicherlich die Tatsache, daß mammographisch entdeckte Primärtumoren zumeist auch eine radiologische Diagnostik des Rezidivs ermöglichen. Besonderes Augenmerk muß bei der Nachsorge auf das Tumorbett gerichtet werden, da sämtliche Lokalrezidive vom Tumorbett ihren Ausgang nahmen. Schließlich sind nicht sicher im Gesunden entfernte Tumoren und Patienten mit Lymphknotenbefall als Risikopatienten für Lokalrezidive anzusehen.

    Notes: Abstract In 12 severely burned patients the input of fluid and sodium, as well as sodium concentration in plasma and urine, was studied. The osmolarity in plasma and 24-h urine was measured. The high initial sodium input is noted. Plasma sodium levels stay within the normal range when the amount of sodium given during the further treatment is reduced. The importance of urea production in affecting plasma osmolarity is demonstrated.

    Notes: Abstract Exclusive semileptonic decays of heavy mesons provide interesting information on systems consisting of quarks of unequal mass. We express the formfactors of the hadronic current in terms of relativistic bound state wave functions for which we take the solutions of a relativistic harmonic oscillator potential. The wave function overlap is determined by the quark mass dependent longitudinal momentum distribution and differs from results based on non relativistic wave functions. The semileptonic widths and lepton spectra are calculated using in addition nearest pole dominance for the momentum transfer dependence of the formfactors. We compare our results with recent experimental data. The formfactor calculation also allows an estimate of special nonleptonic transitions. From the CLEO results on $$\bar B^0 \to \pi ^ + \pi ^ -$$ and $$\bar B^0 \to D^{* + } + \pi ^ -$$ we find for the corresponding Kobayashi-Maskawa matrix element ratio the limit |V ub /V cb |≲0.3.

    Description / Table of Contents: Summary The plane torsion test serves for determining stress-strain curves of thin sheet metal. When a torque is applied simple shear takes place in the free zone of the specimen and causes principal tensile and compressive stresses. Under certain material and geometrical conditions these compressive stresses may cause buckling of the sheet, so that the assumed state of plane stress and plane strain which enables test evaluation is no longer fulfilled. This limits the applicability of the test. By using the strain energy method the critical conditions for elastic and plastic buckling have been analysed and discussed in comparison with experimentally obtained data. A variation of parameters showed how geometry could be varied in order to decrease the tendency towards buckling.
    Notes: Übersicht Der ebene Torsionsversuch dient zur Aufnahme der Fließkurven dünner Bleche. Durch die Torsionsbelastung im ringförmigen nicht abgestützten Teil der Platine ergibt sich ein Zug-Druck-Hauptspannungszustand, der bei bestimmten Werkstoff- und Geometriegegebenheiten ein Ausknicken des Bleches aus der Ebene bewirkt. Hierdurch wird von den für die Auswertung des Versuches vorausgesetzten ebenen Formänderungs- und Spannungszuständen abgewichen und somit seine Anwendbarkeit begrenzt. Mit Hilfe der Formänderungs-Energie-Methode wurden die kritischen Bedingungen für elastische und plastische Faltenbildung berechnet und experimentellen Ergebnissen gegenübergestellt. Die durchgeführte Variation der Geometrieparameter gibt darüber Aufschluß, durch welche Veränderungen die Faltenbildung unterdrückt werden kann.
