The hydrodynamics of the capillary flow a viscous-plastic liquid in cylindrical rectilinear pores is considered, as result which structural velocity distribution over pore cross section obtained. Analytical solutions are proposed for equations hydraulic diffusion and nonlinear filtration non-Newtonian fluid porous medium. It noted that when flows medium, take form due to effective viscosity, sh...

We created physical models based on the morphology of ram suspension-feeding fishes to better understand the roles morphology and swimming speed play in particle retention, size selectivity and filtration efficiency during feeding events. We varied the buccal length, flow speed and architecture of the gills slits, including the number, size, orientation and pore size/permeability, in our models...

Abstract—The data-based filtration method is proposed on the basis of the recent results for bandwidth selection by using smoothed cross-validation procedure. The optimal regularization procedure was developed to obtain the stable nonparametric estimator of filtration. Simulation has shown a high quality of the proposed filtration estimators as compared with the optimal Kalman filter.

A system of tangential-flow filtration was evaluated for use in the detection of Giardia cysts in drinking water. This method was more sensitive in recovering cysts than a frequently used wound-orlon system of through-filtration.

In anesthetized salt-depleted dogs, infusion of adenosine (20 to 500 fig/min) directly into a renal artery induced an initial decrease of renal blood flow for 1 to 2 minutes but did not change or slightly increased this flow during the steady state. Statistically significant decreases occurred in glomerular filtration rate, filtration fraction, sodium excretion, and renal venous renin activity....

Previous studies suggest that hypoxia and hypercapnic acidosis exert a renal nerve mediated adverse effect on renal haemodynamic function. We therefore examined the effect of hypoxia and hypercapnic acidosis on renal blood flow and glomerular filtration rate responses to lowering renal perfusion pressure from 125 to 75 mmHg in the anaesthetized dog. To study the role of renal nerves in these re...
