TLDR
The equations derived here have been applied to various permeability measurements found in the literature, such as the penetration of heavy water into animal cells, permeability of blood vessels, threshold concentration of plasmolysis and relaxation experiments with artificial membranes.About:

Review of 3D CFD modeling of flow and mass transfer in narrow spacer-filled channels in membrane modules
TL;DR: The robustness, reliability and efficiency of modern numerical methods for obtaining solutions to flow problems have given rise to the adoption of Computational Fluid Dynamics (CFD) as a widely used analysis tool for membrane separation systems.

Estimation of equivalent pore radii of pulmonary capillary and alveolar membranes
AE Taylor,Gaar Ka +1 more
TL;DR: The alveolar membrane represents a tight cellular-type structure, whereas the pulmonary capillary represents a highly permeable, porous structure.
Journal ArticleDOI
Capillary fluid filtration. Starling forces and lymph flow.
TL;DR: The basic forces responsible for maintaining fluid balance between the microcirculation and interstitium are defined, and physiologists have termed tissue pressure, capillary pressure, plasma colloidal osmotic (TTP), and tissue colloidal Osmotic pressure as Starling forces, however, a mathematical relationship between those forces was not formulated by Starling.
Journal ArticleDOI
Membrane permeability modeling: Kedem-Katchalsky vs a two-parameter formalism.
TL;DR: This paper demonstrates that the 2P and KK formalism yield essentially the same result (Lp and Ps) when cotransporting channels are absent, and discusses the phenomenological nature of transport parameters in many experiments, especially when both bilayer and channel transport are present.

TL;DR: In this paper, the authors examined the effect of hydration on the growth rate of a fungal colony and the evolution of germination, sporulation, and metabolic activity of the colony.

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.
