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:

Comparison of non-ideal solution theories for multi-solute solutions in cryobiology and tabulation of required coefficients.
TL;DR: Two non-ideal solution theories for predicting water chemical potential in multi-solute solutions relevant to cryobiology have similar overall performance, and both give more accurate predictions than ideal models.
DissertationDOI
Mixed-dimension models for flow and transport processes in porous media with embedded tubular network systems
TL;DR: In this paper, the authors propose a method to solve the problem of "uniformity" and "uncertainty" in the context of data mining, and propose a solution.

TL;DR: A lab-on-a-chip (LOC) device is developed to quantitatively measure the biomechanical properties of lily (Lilium longiflorum) pollen tubes, finding the turgor pressure and wall stiffness of the pollen tubes are found to decrease considerably with increasing initial diameter.

The role of the microvascular network structure on diffusion and consumption of anticancer drugs
Pietro Mascheroni,Raimondo Penta +1 more
TL;DR: The results show that both drug advection and diffusion are dramatically impaired by increasing geometrical complexity of the microvasculature, leading to nonoptimal absorption and delivery of therapeutic agents.

Diffusive and Convective Flow Across Membranes: Irreversible Thermodynamic Approach
E. H. Bresler,R. P. Wendt +1 more
TL;DR: In this article, the experimentally verified hydrodynamic approach to a description of diffusive and convective flow of solute across mutual membrane pathways is compared with the phenomenological equation resulting from the application of irreversible thermodynamics.

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.
