The aflatoxin B1 degrading abilities of two different ruminants were compared in this study. One set of experiments evaluated the aflatoxin B1 degradation ability of different rumen fluid donors (steers vs. goats) as well as the rumen fluid filtration method (cheese cloth filtered vs. 0.45 microm Millipore) in a 2 x 2 factorial arrangement. Additional studies examined aflatoxin B1 degradation b...

Mass, energy, and momentum transfer processes between fluid-saturated porous media the adjacent free flow occur in many natural technical systems. The dynamics region is strongly controlled by mechanisms at common interface conditions on outer surface of free-flow. present paper considers unsteady axisymmetric flows viscous fluids through an annular domain with a layer covering cylindrical soli...

Twenty five patients with oliguric renal failure were treated by a combination of continuous arteriovenous haemofiltration and intermittent haemodialysis over 18 months. Haemofiltration was given for a mean of 6.6 days and the mean filtration volume was 6.0 1/day. Fourteen of the 25 patients survived beyond two months after the period of oliguria. Haemofiltration proved to be a simple and effec...

The renal response to chronic depletion of extracellular volume was examined using the techniques of micropuncture. Depletion of salt and water was produced by administration of furosemide to rats maintained on a sodium-free diet. There was a marked fall in body weight, plasma volume, and glomerular filtration rate. The intrinsic reabsorptive capacity of the proximal tubule, measured by the spl...

The deposition behaviors of carboxylate-modified polystyrene latex microspheres (six sizes ranging from 0.1 to 2.0 μm) in packed porous media (soda-lime glass beads) were examined under a variety of environmentally relevant pore fluid velocities (4-8 m-day-1) in the presence of an energy barrier to deposition. Hyperexponential profiles of retained colloids were observed for all microsphere size...

Single glomerulus filtration rate in Eptatretus stouti averaged 20.3+/-2.13 (S.E.M.) nl min(-1). Single glomerulus glomerular filtration rate (GFR) could be correlated with arterial pressure when arterial pressure exceeded about 4 cm H2O. Glomerular filtration was affected by postglomerular resistance brought about by alteration of the volume of urinary spaces. Filtration undoubtedly plays a ro...
