The osmotic water permeability coefficient, L(p), for human and dog red cells has been measured as a function of medium osmolality, and found to depend on the osmolality of the bathing medium. In the case of human red cells L(p) falls from 1.87 x 10(-11) cm(3)/dyne sec at 199 mOSM to 0.76 x 10(-11) cm(3)/dyne sec at 516 mOSM. A similar decrease was observed for dog red cells. Moreover, L(p) was...

The latest developments and applications of hollow fiber membrane contactors (HFMCs) were discussed in this recent published book. Membrane contactor provides gas–liquid or liquid–liquid contact without dispersion one phase another, which gives a higher mass transfer coefficient compared to the conventional contactors. Using microporous hydrophobic hydrophilic membrane, fluids is immobilized po...

in this study, the effect of edible coating and osmotic dehydration, as pre-treatments before drying of cucurbit, were investigated. cucurbit samples were cut spirally and coated by carboxy methyl cellulose (cmc) 1% and ascorbic acid 0.1% solutions and then processed by osmotic dehydration. proportion of sample to solution was 1:10 and the solution containing sucrose %45, salt%25 and citric aci...

Abstract It was found that at the time of completion soil compaction it has content moisture ∼ 4-8% and, therefore, osmosis coefficient in initial period road use is minimal. The mutually eliminated by antiosmosis, which determines duration osmotic period. established magnitude influenced factors also affect parameters electric double layer: compaction, mineral composition, type exchangeable ca...

osmotic dehydration under discontinuous reduced pressure is one of the new methods of preparation fruits and vegetable processing with in view of good health. processing of foods at high temperatures used to cook them can cause the formation of carcinogenic substances like acrylamide, and this risk remains even if the trans-fat is removed. the low temperatures employed in this method resulted i...

The osmoregulatory system was studied in wild adult and reared juvenile Persian sturgeon, Acipenser persicus. The mean osmolarity in blood serum of specimens from the Caspian Sea, estuary, the Kouraneski pools and the rearing tanks were 305.3±14.3, 308.7±25.8, 265.0±19.1 and 259.3±8.8 mosmol/L, respectively; the mean concentrations of Na+ were 151.2±6.3, 152.2±8.4, 142.5±5.9 and 131.4±4.1 meq/L...
