    Notes: [Auszug] Identifications and redshifts exist now for all SCR sources that are more than 15 degrees from the galactic equator and that have a 178 MHz flux density S178 exceeding 30 flux units (1 f.u. = 10-26 W m-2 Hz-1). Table 1 gives the flux density Si 7 8, the radio spectral index a = d log Sv/d log v and ...

    Notes: [Auszug] HOYLE'S assertion that only 5 sources per steradian are missing at the bright end1 is based on the apparent Euclidean nature of the source counts. My derivation of the steady-state source counts2 expected if radio galaxies have cosmological redshifts shows that the Euclidean slope of ...

    Notes: [Auszug] Since a major step in the formation of gall-stones appears to be the bacterial 7-dehydroxylation of allocholic acid, it is reasonable to assume that the reduction or elimination of the bacteria responsible for the conversion might interfere with gall-stone formation. Because of its well-known ...

    Notes: The suspension polymerization of vinyl chloride is studied in a bench-scale reactor adequately reproducing reaction conditions and resin properties of industrial relevance. The evolution of particle morphology is analyzed at different stages of conversion, and a model for particle formation is verified. The influence of viscosity of the suspension medium is analyzed in relation to molecular weight distribution and particle morphology.

    Notes: A specific and sensitive method for the determination of ethylenediamine in human plasma is described. The aqueous sample is treated with m-toluoyl chloride, yielding the N,N′-bis(m-toluoyl) derivative of the diamine, which is extracted into dichloromethane and quantitated after “on column” methylation by capillary gas liquid chromatography with alkali flame ionization detection. The corresponding derivative of putrescine serves as internal standard. The assay is reproducible and calibration curves are linear over the concentration range 0.05 to 10 μg · ml-1. The lower detection limit is about 10 ng · ml-1. The structures of the compounds of interest eluting from the capillary column are examined by gas liquid chromatography/mass spectrometry. The assay has been applied to the analysis of ethylenediamine in plasma following the administration of aminophylline and ethylenediamine in a cross-over study to patients with bronchopulmonary diseases. The method also proves suitable for measuring other primary and secondary amines and diamines in aqueous solutions by gas liquid chromatography.

    Notes: The big success of the reaction injection molding (RIM) process has brought about a marked interest in reacting polymer processing. In the present work, we study the technical feasibility of a continuous process to coat metallic conductors using reacting polymers. In the envisioned system, RIM type reactants are mixed and then injected into a tubular reactor through the center of which we pass the cable to be coated. The predictions of the mathematical model developed show that a feasible process can be designed by adequate control of the heat transfer phenomena. The process needs in general, a low reactor temperature and a high cable temperature.

    Notes: Es wurde eine mehrstufige Rieselboden-Wirbelschicht für Wärme- und Stoffübergangsprozesse mit kontinuierlichem Partikeldurchfluß entwickelt, in der die Partikeln und das Durchströmmedium im Gegenstrom gleichmäßig über den gesamten Apparatequerschnitt dieselben Bodenöffnungen passieren. Untersucht wurde das System Feststoff/Luft. In einem Arbeitsdiagramm werden der Druckverlust und die Partikelkonzentration je Stufe in Abhängigkeit vom Durchsatz des Wirbelmediums und von den Feststoffeigenschaften mitgeteilt. außerdem wurden die mittlere Verweilzeit der Partikeln und die Verweilzeitverteilung untersucht. In jeder Stufe liegt nahezu ideale Durchmischung vor, und die Verweilzeitstreuung nimmt mit der Wurzel aus der Stufenzahl ab.
