One framework type of high-silica zeolite only can effectively remove a limited range organic micropollutants (OMPs) from water. In order to extend the OMP removal range, different types zeolites need be combined in adsorption process. this study, Mordernite (MOR) and ZSM-5 (MFI) powders were mixed mass ratios. The performances eight OMPs by mixtures, as well single MOR MFI zeolites, evaluated ...

MARSH, DONALD J., AND LEE A. SEGEL. Analysis of countercurrent di$usion exchange in blood vessels of the renal medulla. Am. J. Physiol. 221(3): 817-828. 1971 .-A model of the vasa recta was developed to explore the significance of dissimilarities between ascending and descending vasa recta for countercurrent exchange efficiency, and also to examine the interaction between countercurrent exchang...

The mathematical description of hemodialysis (HD) includes two parts: 1) explanation of the exchange between patient’s blood and dialysate fluid across a semipermeable membrane of the dialyzer, and 2) characterization of the solute removal from the patient. The solute transport across the dialyzer membrane depends on the difference in hydrostatic pressure and solute concentration gradients betw...

background and purpose: the 2-chlorophenol (2-cp) and 4-chlorophenol (4-cp) are phenolic compounds which may have adverse effects on human and environment. therefore, removing these compounds from water and wastewater is necessary. this study aims to analyze 2-cp and 4-cp removal by using azolla filiculoides biomass. materials & methods: azolla biomass was sun dried, crushed and sieved to parti...

A computer program has been developed to aid the analysis of molecular dynamics trajectories. The program is tuned for macromolecular large-scale problems and supports features such as removal of global translations-rotations of the solute, calculation of average distance maps and their corresponding standard deviations, calculation of the variance-covariance and cross-correlation matrices, and...

The filter membrane in a CRRT extracorporeal circuit is vitally important for several reasons. Because it has the largest degree of exposure to blood of all circuit components, the membrane is the most important determinant of the circuit’s overall biocompatibility. In addition, membrane characteristics determine both the solute removal and water permeability properties of a CRRT filter. The fo...
