    Notizen: Little attention has been paid to the flow distribution among many thousands of fibers in the hollow-fiber modules of artificial kidney, ultrafiltration, and reverse osmosis devices despite its potential importance in the efficiency of the module. Numerical study by a finite-difference method, as well as experiment by direct sampling from individual fibers and high-speed photography of a color tracer, has shown that there exists a significant degree of nonuniformity in the flow distribution, which depends on the manifold design, the Reynolds number, and the pressure drop along the fibers.

    Notizen: ---A,C-Bridged (ACCX) and A,D-bridged isopropyldimethylsilylcalix[6]arene (ADCX) dissolved in OV-1701 were used as stationary phases in isothermal capillary gas chromatographic separation of some positional isomers. Retention factors and separation factors for the isomers were measured. The isomers investigated are well resolved on the two phases. Retention of all the solutes investigated is longer on ACCX than on ADCX. The longer retention on A,C-bridged calix[6]arene is probably due to extra inductive interactions of the solute molecule with the carbonyl moieties in the phase. Separation factors for closely eluting isomer pairs are similar on the two phases. This seems to indicate that the carbonyl moieties do not play an appreciable role in discriminating the isomer molecules on entering the cavity of the calixarene if the solute is retained by the inclusion process.
