The following study of the head loss in filters, whether of upstream or downstream flow, is of main importance in the projection and mainly in the operational control of such units in a water treatment plant (WTP). However, ...

Slow sand filtration is an efficient water treatment technique used for treating surface water with relatively low levels of contamination. Despite the slow sand filtration at pathogen, algae and cyanobacteria removal ...

OBJECTIVE: Pneumoperitoneum during laparoscopy results in transient oliguria and decreased glomerular filtration and renal blood flow. The presence of oliguria and elevated serum creatinine is suggestive of acute renal ...

Records of the electrical impedance were obtained by means of surface electrodes placed on ventral and dorsal sides of the left kidney of anesthetized dogs. Changes of the renal electrical impedance resulted from alterations ...

Este estudo avaliou a redução da taxa de kerma no ar, o espectro de energia dos raios X e alterações na qualidade da imagem radiográfica. Comparações com várias espessuras do filtro de liga de alumínio-cobre em três ...

Pre-filtration followed by slow filtration is highlighted by its ability to promote greater efficiency in removing variable physical characteristics from raw water. The study aimed to apply different filtration rates to ...
