    Notes: [Auszug] In the experiments described here, the reduction of NAD was studied by coupling it to a system which utilizes NADH, namely the synthesis of glutamate from a-oxoglutarate and ammonia4. Table 1 shows that oxygen at 3 atm. has no effect on the synthesis of glutamate, even after pre-incubation for 60 ...

    Description / Table of Contents: Abstract In formulating technical equations of state, series expressions are used which are analytic at the critical point as the classical van der Waals equation of state is. In many cases the analytical formulation is considered to be the physically necessary principle. In recent years, however, detailed experimental and theoretical research has shown that changes of phase at critical points have an asymptotic nonanalytic character and assumption of an analytic equation of state at the critical point appears unrealistic. An equation of state is suggested, non-analytic at the critical point, which provides good representation of experimental data and possible expansion into the gas- and liquid region.
    Notes: Zusammenfassung Bei der Aufstellung von technischen Zustandsgleichungen benutzt man meist Reihenentwicklungen, die am kritischen Punkt, wie auch die klassische van der Waals'sche Zustandsgleichung, analytisch sind. Dabei wird vielfach die analytische Formulierung als physikalisch not-wendiges Prinzip vertreten. In den letzten Jahren aber wurde durch eingehende experimentelle und theoretische Forschung deutlich, daß Phasenübergänge an kritischen Punkten einen asymptotischen nicht-analytischen Charakter haben und die Annahme einer am kritischen Punkt analytischen Zustandsgleichung sehr unrealistisch ist. Es wird eine Zustandsgleichung vorgeschlagen, die am kritischen Punkt nicht analytisch ist, die Meßwerte gut wiedergibt und nach der Gas- und Flüssigkeitsseite hin leicht zu erweitern ist.

    Notes: In der Nähe des kritischen Zustandes bildet sich infolge der hohen Kompressibilität in einem ruhenden fluiden Medium eine mit der Höhe veränderliche Dichte aus. Diese Dichteschichtung wurde an CO2, N2O und CF3Cl sowie an Gemischen aus diesen Stoffen über die örtliche Brechzahl bestimmt. Die Versuchsapparatur wurde besonders sorgfältig auf konstanter Temperatur gehalten, so daß einwandfreie Gleichgewichtszustände erzielt wurden. Aus den Ergebnissen lassen sich die Grenzkurve, die Dampfdruckkurve und das Druck-Dichte-Diagramm in der Nähe des kritischen Zustandes mit größerer Genauigkeit bestimmen, als es durch die bisher übliche Messung von Mittelwerten der Dichte möglich war.
