    Notes: A field experiment has been installed near Firebaugh in the San Joaquin Valley of California to test submergence of drains as a means of denitrification of ground water. Laboratory and field experiments have shown that denitrification occurs in saturated soil where there is ample organic carbon available for bacterial metabolism. Denitrification and dilution of high nitrate ground water were accomplished in the field.

    Notes: [Auszug] A mass ejected from the Earth into a heliocentric orbit, as part of the new orbit, must return to a heliocentric distance corresponding to the launch point. This fact is well documented by the orbital parameters observed for the heliocentric deep space probes launched between 1958 and 1967 (Table ...

    Description / Table of Contents: Zusammenfassung CNDO-Rechnungen wurden benutzt, um die Einzentren-Rumpf-Integrale für protonierte Azine zu erhalten, die bei der Berechnung der π→π * -Absorptionsspektren mit Hilfe der PPP-Methode benötigt werden. Die berechneten Spektren für die Ausgangsmoleküle und die protonierten Moleküle sind in zufriedenstellender Übereinstimmung mit dem Experiment. Die Veränderungen im σ-Rumpf der Moleküle bei der Protonierung werden ebenfalls mit Hilfe der CNDO-Resultate diskutiert.
    Abstract: Résumé Des CNDO ont tét utilisés pour obtenir les intégrales de coeur monocentriques des azines protonées nécessaires au calcul de leur spectre d'absorption π→π * par la méthode PPP. Les spectres calculés pour les molécules protonées ou non sont en accord satisfaisant avec l'expérience. Les modifications subies lors de la protonation par le squelette σ sont discutées en fonction des résultats des calculs CNDO.
    Notes: Abstract CNDO calculations have been used to obtain the one-centre core integrals for protonated azines required in calculating the π→π * absorption spectra of such molecules using the PPP method. Calculated spectra for both the parent and the protonated molecules are obtained in satisfactory agreement with experiment. The changes in the σ-framework of the molecules on protonation are also discussed in terms of the CNDO results.
