We characterized immunoglobulin G (IgG) transport across rat alveolar epithelial cell monolayers cultured on permeable supports. Unidirectional fluxes of biotin-labeled rat IgG (biot-rIgG) were measured in the apical-to-basolateral (ab) and opposite (ba) directions as functions of [rIgG] in upstream fluids at 37 and 4 degrees C. We explored specificity of IgG transport by measuring fluxes in th...

The basic governing equations in anisotropic elastic material under the effect of porous piezothermoelastic are presented. Biot [1], Lord & Shulman [4] and Sherief et al. [5] theories are used to develop the basic equations for porous piezothermoelastic with mass diffusion material. The variational principle, uniqueness theorem and theorem of reciprocity in this model are established under the ...

While the Hasimoto planar vortex filament is one of few exact solutions to the local induction approximation (LIA) approximating the self-induced motion of a vortex filament, it is natural to wonder whether such a vortex filament solution would exist for the non-local Biot-Savart dynamics exactly governing the filament motion, and if so, whether the non-local effects would drastically modify th...

The stability analysis of Marangoni convection in porous media with a deformable upper free surface is investigated. The linear stability theory and the normal mode analysis are applied and the resulting eigenvalue problem is solved exactly. The Darcy law and the Brinkman model are used to describe the flow in the porous medium heated from below. The effect of the Crispation number, Bond number...

We simulate wave propagation in a partially saturated porous medium, where the novel feature is the presence of a second slow wave due to capillary forces. The pores are filled with a wetting fluid and a non-wetting fluid, and the model, based on a Biot-type three-phase theory, predicts three compressional waves and one shear wave. Moreover, the theory models the realistic attenuation levels ob...
