Biophysics Oxygen permeability of phosphatidylcholine - cholesterol membranes ( pulse ESR / permeability coefficient / oxygen transport ) WITOLD

Oxygen transport in phosphatidylcholinecholesterol membranes has been studied by observing the collision of molecular oxygen with nitroxide radical spin labels placed at various distances from the membrane surface using long-pulse saturation recovery ESR techniques. The collision rate was estimated for tempocholine phosphatidic acid ester, 5-doxylstearic acid, and 16-doxylstearic acid from spin...

Swimbladder Permeability to Oxygen

The permeability of the swimbladder to gas was measured as the conductance to oxygen in seven species of fish. The low over-all conductance resides in the low diffusion constant, K, of the middle layer of the wall (submucosa) while the outer and inner layers (tunica externa and mucosa) have diffusion constants similar to other vertebrate tissues. The low diffusion constant is due to a low diffu...

Application of Gene Expression Programming to water dissolved oxygen concentration prediction

This research based on record and collected data from four stations at Eymir Lake, Turkey, which are monitored daily in seven months. Water quality monitoring using former methods are time-needed and expensive, while the application of gene expression programming is more understandable, rapid, and reliable which is used in this article to provide a prediction for dissolved oxygen. The concentra...

On the Effective Permeability of Mixed Matrix Membranes

Mixed matrix membranes (MMMs) are attracting significant interest for pervaporation and gas separation applications. To better comprehend the impact of filler particles within polymer matrices, the species permeation mass transport was theoretically studied by numerical simulation using finite differences. The Fick’s second law of diffusion was solved for a three-dimensional MMM to obtain the c...

Rapid Changes in Permeability of Cell Membranes to Water Brought About by Carbon Dioxide & Oxygen.

on the permeability of protoplasmic membranes to water. Our experimental tissue was the hypocotyl of Helianthus annuus. We have observed the effect of such factors on the permeability of the cells toward water passing both in the inward and in the outward directions. The rate of entry of water into uniform segments of tissue is a function of A, the difference in diffusion pressure deficit (DPD)...
