We investigate the formation of fingered flow in dry granular media under simulated rainfall using a quasi-two-dimensional experimental setup composed of a random close packing of monodisperse glass beads. Using controlled experiments, we analyze the finger instabilities that develop from the wetting front as a function of fundamental granular (particle size) and fluid properties (rainfall, vis...

I. A study was made of the changes in electrolyte concentrations and ruminal function which resulted from the provision of 1.3 7; sodium chloride solutions instead of fresh water to sheep consuming roughage rations in chaffed and in ground pelleted forms. 2. Significantly higher osmotic pressures were observed in the rumen fluid of the sheep drinking saline water, the change being especially ma...

Introduction The ability ofthe kidney to conserve or excrete free water independent of changes in solute excretion was a prerequisite for the successful adaptation of vertebrates to prolonged periods on land (1, 2). Renal conservation of water in amphibia, reptiles, birds, and mammals is controlled by antidiuretic hormone (ADH)."2 In these animals, body fluid osmolality is maintained within ver...

background the chemical and physical quality of water used for dialysis fluid is a vital factor in the patients overall care who receive dialysis. therefore, the water used for this purpose must be treated with advanced methods before being used for dialysis. conclusions the evaluation of hemodialysis water quality showed that these hospitals were not significantly polluted and the water qualit...

Displacement of oil and water in porous media of reservoir rocks is described by relative                      permeability curves, which are important input data for reservoir performance simulation and drive mechanism studies. Many core studies, such as multiphase relative permeability, capillary pressure and saturation exponent determination, depend on the volume fractions of multiphase flui...

The present article provides a theoretical description of the changes of interstitial hydrostatic pressure, tissue hydration, and protein distribution in the tissue during a peritoneal dwell with isotonic fluid. The mathematical model is based on the concept of uniformly distributed capillary and lymphatic systems within a deformable, porous tissue. Protein transport was analyzed for diffusive ...

Deep-subsurface samples obtained by deep drilling are likely to be contaminated with mesophilic microorganisms in the drilling fluid, and this could affect determination of the community structure of the geothermal microflora using 16S rRNA gene clone library analysis. To eliminate possible contamination by PCR-amplified 16S rRNA genes from mesophiles, a combined thermal denaturation and enzyme...

The unique properties of brain capillary endothelium, critical in maintaining the blood-brain barrier (BBB) and restricting water permeability across the BBB, have important consequences on fluid hydrodynamics inside the BBB hereto inadequately recognized. Recent studies indicate that the mechanisms underlying brain water dynamics are distinct from systemic tissue water dynamics. Hydrostatic pr...

Introduction Water is the most abundant constituent of the human body. Human body has 60-70 % of weight due to its water content 1 . Water occupies two main fluid compartments 1. Intracellular fluid (ICF)about two third by volume, contained in cells 2. Extracellular fluid (ECF)-about one third by volume, consist of two major subdivisions  Plasma – the fluid portion of the blood  Interstitial ...
