The energetic properties of ternary Zr–Nb–Sn Zirconium-based alloy with concentration dissolved alloying elements ∼ 1 . 5 % are studied by using density functional theory. possibility additions separated different distances to dissolve/segregate in a host matrix is analyzed the help mixing energy and solute–solute binding energy. ability solutes trap single vacancy discussed studying formation ...

The solute removal characteristics and haemocompatibility of low-flux dialysers containing Cuprophan, cellulose acetate, polymethylmethacrylate (PMMA), and polycarbonate-polyether (Gambrane) membranes were compared in a multicentre cross-over clinical trial. While all four dialysers provided comparable removal of urea and creatinine, the dialyser containing PMMA membrane showed a reduced abilit...

The objective was to test the hypothesis that the optimal cryoprotective agent for cryopreservation of human spermatozoa would be a solute for which cells have the highest plasma membrane permeability, resulting in the least amount of volume excursion during its addition and removal. To test this hypothesis, theoretical simulations were performed using membrane permeability coefficients to pred...

This study investigated the removal of trace organic contaminants by a combined membrane bioreactor - granular activated carbon (MBR-GAC) system over a period of 196 days. Of the 22 compounds investigated here, all six hydrophilic compounds with electron-withdrawing functional groups (i.e., metronidazole, carbamazepine, ketoprofen, naproxen, fenoprop and diclofenac) exhibited very low removal e...

Toxic organic substances are considered among the pollutants that have direct effect on humans and animals. Industrial wastewaters containing dissolved phenol compounds can contaminate groundwater resources and thus lead to a serious groundwater pollution problem. In the present research, the adsorption technique for the efficient removal of organic substances at trace level was employed. It is...

Cardiac dysfunction is a key factor in the high morbidity and mortality rates seen in hemodialysis (HD) patients. Much of the dysfunction is manifest as adverse changes in cardiac and vascular structure prior to commencing dialysis. This adverse vascular remodeling arises as a dysregulation between pro- and antiproliferative signaling pathways in response to hemodynamic and nonhemodynamic facto...

Low-solute hyponatremia is a relatively uncommon entity of euvolemic hyponatremia. Classic cases were described in alcoholics as beer potomania, which is characterized by hyponatremia in the setting of low-solute intake due to heavy beer drinking. We report a case of low-solute hyponatremia in a nonalcoholic person who was given a solute load, and, subsequently, had excessive diuresis with the ...

Solute transport in soils is commonly simulated with the advective-dispersive equation, or ADE. It has been reported that this model cannot take into account several important features of solute movement through soil. Recently, a new model has been suggested that results in a solute transport equation with fractional spatial derivatives, or FADE. We have assembled a database on published solute...
