A fiber matrix model of capillary permeability.
The observation that ferritin is excluded from the luminal vesicles and the luminal surface of endothelial cells has led one of us (Michel, 1978a, 1979) to reintroduce the idea that the molecular sieving properties of the capillary wall may reside in an endocapillary layer rather than in the dimensions of pores through or between the endothelial cells. It is suggested that the endocapillary lay...
متن کاملConstant-pressure Measurement of Steam-water Relative Permeability
A series of steady-state experiments have established relative permeability curves for two-phase flow of water in a porous medium. These experiments have minimized uncertainty in pressure, heat loss, and saturation. By attempting to maintain a constant pressure gradient, the experiments have provided a baseline from which to determine the effect of temperature on relative permeability. The use ...
متن کاملPermeability of electrospun fiber mats under pressure driven flow
Hydraulic permeability of electrospun fiber mats under flow-induced compression has been modeled and verified experimentally. The permeation model accurately estimates the changes in solidity, and hence the permeability of the electrospun mats, over a range of pressure differentials. The model is based on Darcy’s law applied to a compressible, porous medium, using Happel’s equation for the perm...
متن کاملComparison of Permeability and Drying Shrinkage of Self Compacting Concrete Admixed with Wollastonite Micro Fiber and Flyash
Cement substitution in self compacting concrete (SCC) is emphasized to conserve environment, reduce cost and utilize waste materials. This paper focuses on comparing the permeability and drying shrinkage of SCC containing Wollastonite micro fiber (WMF), a cheap pozzolanic fiber with respect to flyash. Microsilica was added for providing required viscosity to maintain homogeneity of the mixes. T...
متن کاملMechanical ventilation and elastic fiber assembly.
ELASTIN IS A CONSTITUENT of connective tissue that is present in virtually all vertebrate tissues and has an especially vital role in organs that undergo repeated cycles of extension and recoil such as the arteries, lungs, and skin. Elastic fibers consist of two morphologically distinct components, the microfibrils and polymerized tropoelastin. The current view is that elastin is secreted from ...
