    Notes: [Auszug] The purpose of the investigation described in this communication was to estimate the rate of elimination of phenylalanine from the blood. We tested seventeen healthy adults, nine heterozygotes, and six phenylketonurics. First we obtained a fasting specimen of capillary blood by means of a ...

    Description / Table of Contents: Summary 1. The phenylalanine tolerance was estimated after intravenous injection of L-phenylalanine in premature newborns, mature newborns, infants and normal adults. The elimination of phenylalanine from the blood followed the pattern of a monomolecular reaction. The rate of elimination was, therefore, chosen for the comparison of the degree of tolerance. 2. The tolerance of phenylalanine was markedly reduced in most of the prematures; the same was found in some of the mature newborn infants. Compared with the tolerance in adults there was no decrease of phenylalanine tolerance in most of the mature newborns and in all infants. 3. The relation of phenylalanine tolerance to the activity of phenylalanine hydroxylase and to the development of the phenylalanine hydroxylase system was discussed.
    Notes: Zusammenfassung 1. Die Phenylalanin-Toleranz wurde vergleichend bei Frühgeborenen, reifen Neugeborenen, Säuglingen und Erwachsenen bestimmt. Die Untersuchung erfolgte nach intravenöser Injektion von L-Phenylalanin. Die Elimination von Phenylalanin aus dem Blut erfolgte entsprechend einer Exponentialfunktion. Zur Beurteilung des Toleranzgrades wurde die Eliminationshalbwertszeit gewählt. 2. Die Phenylalanin-Toleranz war bei den meisten Frühgeborenen herabgesetzt. Bei reifen Neugeborenen kamen Toleranzverminderungen vor; sie waren jedoch wesentlich seltener. Die meisten Neugeborenen und alle Säuglinge zeigten eine Phenylalanin-Toleranz, die der beim normalen Erwachsenen entspricht. 3. Es werden die Beziehungen diskutiert, die zwischen der Phenylalanin-Toleranz und der Aktivität der Phenylalaninhydroxylase bestehen, und es wird auf die bei neonatalen Tieren beobachteten Aktivitätsverminderung des Phenylalaninhydroxylase-Systems hingewiesen.

    Notes: Abstract A heat flow model is presented of the solidification process of a thin melt layer on a heat conducting substrate. The model is based on the two-dimensional heat conduction equation, which was solved numerically. The effect of coexisting regions of good and bad thermal contact between foil and substrate is considered. The numerical results for thermal parameters of the Al-Cu eutectic alloy show considerable deviations from one-dimensional solidification models. Except for drastic differences in the magnitude of the solidification rate near the foil-substrate interface, the solidification direction deviates from being perpendicular to the substrate and large lateral temperature gradients occur. Interruption of the thermal contact may lead to back-melting effects. A new quantity, the effective diffusion length, is introduced which allows some conclusions to be drawn concerning the behaviour of the frozen microstructure during subsequent cooling.

    Description / Table of Contents: Zusammenfassung Lösungen von Rutheniumnitrosylnitro-, Rutheniumnitrosylnitronitrato- und Rutheniumnitrosylnitrato-Komplexen lassen sich mit Hilfe von Papierelektrophorese, Extraktions-Chromatographie und Extraktionen eindeutig voneinander unterscheiden. Kontaktzeit, HNO3-Konzentration, NO 3 − -Konzentration, HDBP-Gehalt der organischen Phase und Zusatz von F−, SO 4 2− , H2PO 4 − und C2O 4 2− beeinflussen stark die Extraktion der Rutheniumnitrosylnitrato-Komplexe mit TBP in Dodecan.
    Notes: Summary Solutions of ruthenium-nitrosyl-nitro, ruthenium-nitrosyl-nitro-nitrato and ruthenium-nitrosyl-nitrato complexes can be distinguished clearly from each other by means of paper electrophoresis, extraction chromatography and extractions. The contact time, HNO3-concentration, NO 3 − -concentration, HDBP-content of the organic phase and the addition of F−, SO 4 2− , H2PO 4 − and C2O 4 2− exert a strong influence on the extraction of the ruthenium-nitrosyl-nitrato complexes with TBP in dodecane.
