Simultaneous capillary dominated displacement of the wetting and non-wetting phases are processes of interest in many disciplines including modeling of the penetration of polluting liquids in hydrology or the secondary migration in petroleum reservoir engineering. Percolation models and in particular invasion percolation is well suited to characterize the slow immiscible displaceme...
capillary electrophoresis (ce) with indirect uv detection is an interesting analytical method for the analysis of drugs and pharmaceuticals. good and reproducible capillary quality is needed to develop robust methods and to facilitate method transfer in ce. it is widely accepted that preconditioning procedures are indispensable in capillary electrophoresis in order to achieve reproducibility of...
simultaneous capillary dominated displacement of the wetting and non-wetting phases are processes of interest in many disciplines including modeling of the penetration of polluting liquids in hydrology or the secondary migration in petroleum reservoir engineering. percolation models and in particular invasion percolation is well suited to characterize the slow immiscible displacement of two flu...
We discuss the problem of trapping and mobilization of nonwetting fluids during immiscible two-phase displacement processes in porous media. Capillary desaturation curves give residual saturations as a function of capillary number. Interpreting capillary numbers as the ratio of viscous to capillary forces the breakpoint in experimental curves contradicts the theoretically predicted force balanc...
hemangiomas are considered as vascular malformations which are categorized by the type of vascular channel to capillary, cavernous, venous or arteriovenous(1). their usual locations are soft tissue , cutaneous or subcutaneous tissue and bone especially vertebra(2).however, intradural extramedullary hemangiomas are rare and most of them fall in cavernous type category. hereby, authors report a w...
Glomerular development of the kidney was studied in newborn rats by electron microscopy. Four different stages of glomerular development were defined: vesicle fonnation, S-shaped body stage, capillary loop fonnation, and glomerular maturation. In the fust stage, the mesenchymal cells form a spheroid mass. This is followed by the S-shaped body stage in which clefts appear in the mass. Afte...
