This work presents the design, fabrication, and testing of a cross-flow filtration microdevice, for the continuous extraction of bacteria from a whole blood sample for the treatment of sepsis and bacteremia. The system consists of a two-compartment microdevice with two aligned sets of PDMS microchannels, separated by a porous polycarbonate (PCTE) membrane with 2 m pores. When a whole blood sam...

To determine the physiological basis for the low glomerular filtration rate in chronic malnutrition, micropuncture studies were performed in Munich-Wistar rats chronically pair-fed isocaloric diets of either low (group 1, nine rats) or high protein content (group 2, nine rats). Despite the absence of hypoalbuminemia, average values for single nephron and total kidney glomerular filtration rate ...

Biofilm attachment and growth in membrane filtration systems are considerably influenced by the localized flow inside feed channel. The present work aims to map biofilm attachment/growth mechanism under varying conditions. Effect of clearance region (space between spacer filament surface) on biofouling pattern is investigated using three 3D-printed pillar spacers having different diameters 340,...

slow sand filtration (s.s.f) is a main process in the water treatment technology and generally considered as most appropriate for application in rural and small urban areas in developing countries. however, performance of the s.s.f is very sensitive to high turbidity levels. therefore, pretreatment is necessary for such waters. horizontal - flow roughing filtration (hfrf) and direct horizontal ...
