    Description / Table of Contents: Zusammenfassung SRS-C tritt in Perfusaten von Meerschweinchenlungen auf, wenn Phospholipase A-haltige Gifte einwirken. Sie wurde aus den Perfusaten angereichert. Die Wirkung von SRS-C beruht im wesentlichen auf Prostaglandinen, z.T. auf Peroxyden. Beide stammen von mehrfach ungesättigten Fettsäuren ab. Die freigesetzten Prostaglandine sind nur z. T. im Gewebe vorgebildet, der größere Teil entsteht neu nach Abspaltung der als Vorstufen dienenden Fettsäuren aus Phosphatiden. In den Lungenphosphatiden selbst wurde Prostaglandin als Bestandteil nicht gefunden.
    Notes: Summary SRS-C appears in perfusates of guinea-pig lungs when the lungs are treated with phospholipase A or venoms containing this enzyme. SRS-C has been concentrated and purified from such perfusates. The biological activity of SRS-C depends mainly on the presence of prostaglandins and to a minor degree also on peroxides. Both compounds originate from unsaturated fatty acids. The liberated prostaglandins are only partially preformed. The bulk of them is formed after cleavage of the precursor acids from tissue phosphatides. Prostaglandins have not been detected as constituents of lung phosphatides.

    Notes: A formula has been determined which satisfactorily represents, for the existing data, the frictional characteristics of the turbulent flow of a dilute viscoelastic non-Newtonian fluid in a pipe. This formula contains two elastic fluid parameters, one of which is strongly dependent on both polymer solute and concentration and the other appears to be a constant and independent of the polymer solutes which were used in this report. A rheometer is proposed based on this formula which should be useful in classifying fluids of this type.

    Notes: Removal of methane from a helium stream by adsorption on Columbia SXC activated carbon was studied experimentally and theoretically. A mathematical model for the process was developed and the governing differential equations were solved numerically. The model incorporates heat and mass transfer resistances within and around the adsorption particle. Wall effects and moderate heat loss to the surroundings are also included. The required heat and mass transfer correlations were obtained from the literature. Simple expressions were developed to determine the relative resistances for heat and mass transfer within and around the adsorption particles.
