    Notes: Summary We found no overall correlation between mitochondrial swelling and PDG activity under many different conditions. We conclude that augmented PDG activity in acidosis is not related, at least to any great extent, to increased anion permeability produced by mitochondrial swelling.

    Notes: Summary Sera from partially hepatectomized rats (PH) compared to sera from control rats (C) enhance liver slice DNA synthesis but depress kidney slice DNA synthesis. Alone, liver extracts from PH do not affect DNA synthesis; but adding sera to PH extracts stimulates, suggesting that sera and liver factors from PH may participate in compensatory growth.

    Notes: Summary Wistar Kyoto rats (WKy), the most widely accepted control for SH rats, show an inability to excrete acid appropriately when compared to another normotensive strain, SD. Coupled with the fact that KWy also develops ‘sodium-sensitive’ hypertension, this makes them a more complex control than realized. At very young ages (〈10-week-old), neither SH nor WKy show any deficiency in acid excretion.

    Description / Table of Contents: Abstract There existes a relation between a definition for the quality of an approximate solution of the Schroedinger equation, earlier given by the auther, and a method of variation, already known, if one introduces the notion „effective potential“.
    Abstract: Résumé La définition de qualité donnée précédemment pour les solutions approximatives de l'équation de Schroedinger peut être liée à un procédé variationel déjà connu, par introduction du „potentiel effectif“.
    Notes: Zusammenfassung Es wird gezeigt, daß die vor einiger Zeit vom Verfasser angegebene Gütedefinition der Näherungslösungen der Schrödingergleichung mit einem schon bekannten Variationsverfahren in Zusammenhang gebracht werden kann, wenn der Begriff des effektiven Potentials eingeführt wird.

    Description / Table of Contents: Abstract Within the frame of the simple one electron approximation it is not possible to define an effective potential. However, if one drops some precularities of this picture one is able to give a sensible definition of an additional potential based on the variation principle. Possibilities of its calculation are indicated.
    Abstract: Résumé On montre qu'un potentiel effectif ne peut pas être défini au cadre de l'approximation naïve des particules indépendantes. L'introduction rationnelle de ce potentiel est possible seulement, si l'on abandonne certaines propriétés de cette approximation. Ensuite on donne une définition du potentiel additionel se basant sur le principe de variation et indiquant de possibilités pour le calcul du potentiel effectif.
    Notes: Zusammenfassung Es wird gezeigt, daß sich im Rahmen einer naiven Einteilchennäherung kein effektives Potential definieren läßt, sondern die sinnvolle Einführung eines solchen nur dann möglich ist, wenn gewisse Züge des Einteilchenbildes fallen gelassen werden. In diesem Zusammenhang wird eine Definition des Zusatzpotentials angegeben, die auf einem Variationsprinzip basiert und Möglichkeiten aufzeigt, wie das effektive Potential bestimmt werden kann.

    Description / Table of Contents: Abstract A new approximation of the potential energy ℰ(R) of diatomic molecules containing a sufficient number of parameters to fulfill all hitherto known conditions is given. The parameters are determined by solving a non homogeneous system of linear equations. This approximation will further yield the energy of the electrons and the one of the repulsion of the nuclei separately, thus making it possible to use the charge of the nuclei for the determination of the approximation parameters. The number of the parameters may be increased without changing the essential features of the formalism. A computation for the H 2 molecule as a test shows that the hitherto known best curve of the ground state of H 2 is very well approximated for all distances of the nuclei.
    Abstract: Résumé Nous proposons une fonction d'approximation pour les courbes de potentiel des molécules diatomiques, qui permet l'introduction, sous forme d'équations inhomogènes entre les paramètres, de toutes les conditions imposées jusqu'ici à detelles fonctions. En plus, cette fonction est la première à reproduire exactement la division de l'énergie totale en énergie électronique et répulsion nucléaire. Ceci permet l'usage direct des charges nucléaires. L'introduction de paramètres additionnels ne change pas le principe du procédé. Des calculs de test sur l'état fondamental du H 2 montrent que notre fonction s'approche excellemment de la meilleure courbe de potentiel connue.
    Notes: Zusammenfassung Es wird eine Näherungsfunktion für die Potentialkurven zweiatomiger Moleküle vorgeschlagen und diskutiert, die mit ihren freien Parametern alle bisher bekannten Forderungen an solche Ansätze in Form, von nicht homogenen linearen Gleichungen für die Parameter zu erfüllen gestattet. Im Gegensatz zu den bisherigen Ansätzen, von denen keiner alle Forderungen erfüllt, gibt darüber hinaus der hier diskutierte Ansatz die Zerlegung der Gesamtmolekülenergie in Elektronenenergie und Kernabstoßungsenergie exakt wieder. Damit werden das erste Mal auch die Kernladungen zur Bestimmung der Approximation herangezogen. Die Verhältnisse bleiben erhalten, wenn die Anzahl der freien Parameter im Ansatz erhöht wird. Testrechnungen am H 2-Molekül zeigen, daß die bisher bekannte beste Potentialkurve des Grundzustandes mit diesem Ansatz für alle Kernabstände vorzüglich approximiert wird.
