Wearable porous PDMS layer of high moisture permeability for skin trouble reduction

Simulation and Experimental Investigation of the Permeability Reduction due to Asphaltene Deposition in Porous Media

Determination of some transport coefficients for the skin and porous layer of a composite membrane

Retention curves, membrane potential, diffusion and electrical resistance for two membranes a composlte membrane (HR 95) and the support membrane (without the skm layer), have been measured for different solutions of NaCl and MgClz Salt permeabllltles m the skm and porous layers of the composite membrane were calculated and these latter values were compared with those obtained mth the porous po...

Modelling of Heat and Moisture Tranferin Porous

The aim of this paper is to demonstrate the mathematical problems of modelling the physical process of heat and moisture transfer in porous materials. The method of discretization in time is applied to derive a discretized (generally non{potential) system of PDEs of elliptic type from the original variational problem of evolution. The convergence of corresponding Rothe sequences is studied.

Reduction of porous media permeability from in situ Leuconostoc mesenteroides growth and dextran production.

In situ growth of bacteria in a porous medium can alter the permeability of that media. This article reveals that the rate of permeability alteration can be controlled by the inoculation strategy, nutrient concentrations, and injection rates. Based on experimental observations a phenomenological model has been developed to describe the inoculation of the porous medium, the in situ growth of bac...
