    Notes: SC and SP were measured simultaneously from opposite hands during a stress period and a subsequent prolonged relaxation in 19 Ss. With the Ss relaxed, toward the end of the session, simultaneous measures of SC and SP were taken between various combinations of two active and two drilled reference electrodes on both hands. It was found that SC measured with the external voltage connected in series-adding with the endogenous SP (i.e., positive pole to the active electrode) was some 13 percent higher than when measured in reverse polarity. Supplementary experiment showed that this‘rectification effect’ could be entirely attributed to the effect of the endogenous potential. A method of estimating SC from SP readings with no external current source was shown to give results equivalent to values measured in the usual way. These and other findings support the claim that steady-state electro-dermal properties fit a simple model consisting of a variable voltage and a variable resistance in series. Within-subject correlations of SC and SP were high for Ss with low average SCs, lower for high-SC Ss who seemed less able to relax. The data suggest that SP may be an inverted-U shaped function of arousal and perhaps that the‘beta process,’ which drives the tonic SP downward with increasing arousal, may begin to function at much lower levels of arousal for some Ss than for others. Phasic responses obtained at the end of the session when some Ss were apparently asleep suggest that, when S is drowsy or in light sleep, both the SCR and the SPR have lengthened and variable latencies, and the SPR is uniformly a large, negative going (alpha) response. Uniphasic beta SPRs were rather consistently obtained when the pre-stimulus tonic SP was already high.

    Notes: Abstract Phase behaviour over regions of the ternary system Na2O/B2O3/Nb2O5 has been explored. Liquidus temperatures and the stability regions of primary phases have been determined over selected composition ranges by high temperature microscopy. Crystallisation processes in melts and corresponding glasses have been followed using both conventional methods of thermal analysis and newly developed micro techniques combined with hot stage microscopy. An electron microscope has been employed to follow changes in the microstructure of quenched glasses after controlled heat treatments. It has been shown that the system contains a liquid immiscibility gap, and some attention is given in the discussions to the influence that can be assigned to cations in determining the extent of such gaps and general structural relationships in borate/oxide systems.

    Description / Table of Contents: Zusammenfassung Unter Benutzung einer früheren Methode wird ein modifiziertes Verfahren zur Berechnung der Rumpfparameter von C-, N- und O-Atomen vorgeschlagen. Die Einzentren-Rumpfparameter H pp 0 werden den üblichen Ionisationspotentialen für die atomaren Valenzzustände gleichgesetzt. Die Zweizentren-Rumpfparameter werden nach H pq 0 = (H pp 0 + H qq 0 )/2 (H pq − 0.0855 R pq + 0.24639) − n p (S pq /4)(γ pp γ + γ pq γ ) − n q (S pq /4) · (γ qq γ + γ pq γ ) berechnet. Auf diese Weise und unter Verwendung der schon früher benützten Coulombintegrale lassen sich die Singulett-Spektren und Ionisationspotentiale einer großen Anzahl ungesättigter Kohlenwasserstoffe sowie der Heterocyclen Pyridin, p-Benzochinon, Pyrrol und Furan mit der üblichen Genauigkeit berechnen.
    Abstract: Résumé Calcul des paramètres de coeur du carbone, de l'azote et de l'oxygène, en utilisant la méthode d'un article précédent techniquement modifiée. Les paramètres de coeur monocentriques H pp 0 sont identifiés avec les potentiels d'ionisation de l'état atomique de valence conventionnel. Les paramètres de coeur bicentriques sont donnée par l'équation H pq 0 = (H pp 0 + H qq 0 )/2 (H pq − 0.0855 R pq + 0.24639) − n p (S pq /4)(γ pp γ + γ pq γ ) − n q (S pq /4) · (γ qq γ + γ pq γ ). On montre que ces paramètres utilisés avec les intégrales de répulsion précédemment adoptées permettent de calculer avec une précision raisonnable le spectresingulet et les potentiels d'ionisation (dans l'approxirnation de Koopmans) pour un grand nombre d'hydrocarbures non saturés et des hétérocycles commee la pyridine, la p-benzoquinone (PBQ), le pyrrole et le furane.
    Notes: Abstract Using the method of a previous paper a modified technique is used to calculate the core parameters for carbon, nitrogen and oxygen atoms. The one-center core parameters H pp 0 , are identified with conventional atomic valence state ionization potentials. The two-center core parameters are given by the equation H pq 0 = (H pp 0 + H qq 0 )/2 (H pq − 0.0855 R pq + 0.24639) − n p (S pq /4)(γ pp γ + γ pq γ ) − n q (S pq /4) · (γ qq γ + γ pq γ ). It is shown that these parameters, along with the electron repulsion integrals adopted earlier allow one to calculate with reasonable accuracy the singlet spectra and ionization potentials (within Koopmans' approximation) of a large number of unsaturated hydrocarbons as well as the heterocycles pyridine, p-benzoquinone (PBQ), pyrrole and furan.
