Hemodialysis removes wastes and water by circulating blood outside the body through an external filter, called a dialyzer, that contains a semipermeable membrane.
22.
Zhou and Dr . Anthony Sun culled islet cells from pig pancreases and encased them in a semipermeable membrane made of seaweed extract.
23.
The incoming flow starting at a low concentration has a semipermeable membrane with water passing to the buffer liquid via osmosis at a small gradient.
24.
Anyway, I already mentioned essentially that technique, but I just refered to it as " a procedure analagous to dialysis " using a semipermeable membrane.
25.
"' Tonicity "'is a measure of the effective osmotic pressure gradient, as defined by the water potential of two solutions separated by a semipermeable membrane.
26.
"' Osmotic pressure "'is the minimum pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.
27.
Although, liquid water will only move in response to such differences in osmotic potential if a semipermeable membrane exists between the zones of high and low osmotic potential.
28.
Further improvement of the dialytrode concept resulted in the invention of the " hollow fiber ", a tubular semipermeable membrane with a diameter of ~ 200-300?m, in 1974.
29.
When heat is transferred, a thermally-conductive membrane is used between the two tubes, and when the concentration of a chemical substance is transferred a semipermeable membrane is used.
30.
Since regions of soil are usually not divided by a semipermeable membrane, the osmotic potential typically has a negligible influence on the mass movement of water in soils.
