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:

Dynamics of fluid movement between intravascular and interstitial spaces
TL;DR: A mathematical expression of the delayed compliance of the vascular and interstitial spaces is given and is taken into consideration in the model and results of simulations of an experimental system are carried out substantiating with good coincidence the experimental findings.
The Dune FoamGrid implementation for surface and network grids
TL;DR: FoamGrid as mentioned in this paper implements one and two-dimensional grids in a physical space of arbitrary dimension, which allows for grids for curved domains, i.e., more than two elements can share a common facet.
Journal ArticleDOI
Electrophysiology of extrafetal membranes.
TL;DR: A literature review of experimental data on potential differences between the fetus, the extrafetal fluid compartments and the mother leads to the conclusion that the transplacental potential difference is no more than a few millivolts and that, in some species, there is an electrical generator outside the placenta.

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.
