However, a large volume and high energy consumption are needed in biotransformation, while the low permeability and stability must be solved in the membrane process.


For low permeability membranes, instability with respect to monotonic finitewavelength perturbations is characteristic.


In this system a water layer overlies a superheatedsteam layer in a reservoir with relatively low permeability located between two parallel highpermeability strata.


It is proposed that low permeability of plasma membranes to water in fractionI seeds results from the predominantly closed aquaporin channels, whereas a higher permeability of weak seeds (fraction II) is due to open channels.


Increased magnesium concentration in the secondary cardioplegia did not provide additional benefit to the ischemic myocardium, possibly due to the low permeability of the sarcolemmal membrane to magnesium.
