Hydration Swelling of Water-Absorbing Rocks: a Constitutive Model
W. K. Heidug,Sau-Wai Wong +1 more
TL;DR: In this paper, a non-equilibrium thermodynamic model of hydration swelling is presented, which is based on extended versions of the equations of poroelasticity and Darcy's transport law.

Determination of optimal cryoprotectants and procedures for their addition and removal from human spermatozoa.
TL;DR: The results indicate that there was a higher recovery of motile spermatozoa after cryopreservation when using 1 M ethylene glycol than with 1 M glycerol, supporting the hypothesis that use of the cryoprotectant for which the cell has the highest permeability will result in higher cell survival.

Filtration, diffusion and molecular sieving through peripheral capillary membranes; a contribution to the pore theory of capillary permeability.
TL;DR: Theoretical and experimental studies on the sieving of molecules by ultrafiltration through porous membranes indicate that an effective pore diameter of at least IOO A would be required to explain permeability of this magnitude.
Journal ArticleDOI
Passage of Molecules Through Capillary Walls
TL;DR: A wealth of evidence supports the view that the exchange of materials through the walls of living capillaries takes place by physical processes which involve no expenditure of energy on the part of the capillary endothelial cells themselves.
