The kedem - katchalsky equations as applied for describing substance transport across biological membranes

open access: yes, 1997
The classical version of the Kedem-Katchalsky equations is suitable for describing substance transport in membrane systems with well-stirred bathing solutions.

Considerations on different thermodynamic models for mass transport across membranes

open access: yes, 1983
The linear Kedem-Katchalsky phenomenological and practical equations are examined in order to show their different information content and the usefulness of the latter as a starting point for a non-linear treatment. A simplified analytical treatment of a

ARTreat project: Three-dimensional numerical simulation of plaque formation and development in the arteries

open access: yes, 2010
Atherosclerosis is a progressive disease characterized by the accumulation of lipids and fibrous elements in arteries. It is characterized by dysfunction of endothelium, vasculitis and accumulation of lipid, cholesterol and cell elements inside blood ...

Derivation of the formula for the filtration coefficient by application of Poiseuille's law in membrane transport [PDF]

open access: yes, 2009
On the basis of Kedem-Katchalsky equations a mathematical analysis of volume flow (Jv) of a binary solution through a membrane (M) is presented. Two cases of transport generators have been considered: hydrostatic (Dp) as well as osmotic (DP) pressure ...

Sodium chloride reflection coefficient in rabbit gall bladder

open access: yes, 1975
By means of the Kedem-Katchalsky thermodynamic description of active transport, a relationship has been derived between the apparent reflection coefficient and the Staverman reflection coefficient for passive transport of a solute which is both actively ...

Electrolyte transport in a central core model of the renal medulla

open access: yes, 1987
Transport of Na+, K+, Cl-, urea, and water is described in a central core model of the renal medulla. Equations for mass balance, Poiseuille flow, and the Nernst-Planck equation describe the continuous behavior of the system along the medullary axis and

Sieving equations and effective glomerular filtration pressure

open access: yes, 1972
Sieving equations and effective glomerular filtration pressure. The curvilinear relationship between the sieving coefficients for 125I-PVP (fractional clearances/GFR) and the radii of hydrodynamically equivalent spheres has been studied in 15 normal ...

A Modified Equivalent Annulus Model for the Hollow Fiber Hemodialyzer

open access: yes, 2004
Experimental approaches to optimize hollow fiber hemodialyzer design are expensive and time-consuming. Computer modeling is an effective way to study mass transfer in the hemodialyzer because a substantial reduction in experimental time and cost can be ...
