Capillary Permeability to Macromolecules [PDF]

open access: bronzeCirculation Research, 1955
Small infusions of dextran fractions having average molecular weights ranging from 10,600 to 412,000 yield plasma to lymph concentration ratios which are directly proportional to molecular weight. The concentration gradient for a specific molecular weight, however, decreases as the volume of infusion is increased. This volume effect, explained in terms

Gas transport and separation with ceramic membranes. Part I: Multilayer diffusion and capillary condensation [PDF]

open access: yes, 1992
Multilayer diffusion and capillary condensation of propylene on supported γ-alumina films greatly improved the permeability and selectivity. Multilayer diffusion, occurring at relative pressures of 0.4 to 0.8 strongly increased the permeability of 6 ...

Transpulmonary thermodilution: its role in assessment of lung water and pulmonary edema [PDF]

open access: yes, 2017
Tissue edema, in particular pulmonary edema, increasingly is recognized as a perioperative complication affecting outcome. Management strategies directed at avoiding excessive fluid administration, reducing inflammatory response, and decreasing capillary

The stability of immiscible viscous fingering in Hele-Shaw cells with spatially varying permeability [PDF]

open access: yes, 2017
In this paper, we investigate the stability of immiscible viscous fingering in Hele-Shaw cells with spatially varying permeability, across a range of capillary numbers.

Effect of Foam on Liquid Phase Mobility in Porous Media [PDF]

open access: yes, 2017
We investigate the validity of the assumption that foam in porous media reduces the mobility of gas phase only and does not impact the liquid-phase mobility.

Simulating temporal evolution of pressure in two-phase flow in porous media [PDF]

open access: yes, 1998
We have simulated the temporal evolution of pressure due to capillary and viscous forces in two-phase drainage in porous media. We analyze our result in light of macroscopic flow equations for two-phase flow. We also investigate the effect of the trapped

Kinetic modeling in the context of cerebral blood flow quantification by H215O positron emission tomography: The meaning of the permeability coefficient in Renkin–Crone׳s model revisited at capillary scale. [PDF]

open access: yes, 2014
One the one hand, capillary permeability to water is a well-defined concept in microvascular physiology, and linearly relates the net convective or diffusive mass fluxes (by unit area) to the differences in pressure or concentration, respectively, that ...

Understanding the Impact of Open-Framework Conglomerates on Water-Oil Displacements: Victor Interval of the Ivishak Reservoir, Prudhoe Bay Field, Alaska [PDF]

open access: yes, 2014
The Victor Unit of the Ivishak Formation in the Prudhoe Bay Oilfield is characterized by high net-to-gross fluvial sandstones and conglomerates. The highest permeability is found within sets of cross-strata of open-framework conglomerate (OFC).

Influence of Capillary Pressure on Estimation of Relative Permeability for Immiscible WAG Processes [PDF]

open access: yes, 2008
Capillary pressure is one of the important parameters when describing flow in porous media. This parameter is nevertheless in some cases neglected, especially if no reliable measured data is available.

The arteriolar vasodilatation model of vibrio cholerae induced diarrhoeal disease [PDF]

open access: yes, 2018
Secretory diarrhoeal disease caused by enterotoxins produced by pathogenic bacteria is characterised by severe fluid loss into the intestine. A prevalent explanation for such high rates of loss, such as occur in episodes of cholera, is that intestinal ...
