Perdas de carga em filtros rápidos de fluxo ascendente e descendente
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Civil, 2018)
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, ...
Utilización de columnas verticales de filtración de manta y arena como pre-tratamiento de un sistema de filtración lenta
(2012-07-09)
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 ...
Serum cystatin C is a sensitive early marker for changes in the glomerular filtration rate in patients undergoing laparoscopic surgery
(Universidade de São Paulo (USP), Faculdade de Medicina, 2014-06-01)
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 ...

Relação entre as variações da impedância elétrica renal com alterações da taxa de filtração glomerular em cães
(1977-12-01)
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 ...

Effects of aluminum-copper alloy filtration on photon spectra, air kerma rate and image contrast
(Fundação Odontológica de Ribeirão Preto, 2004-12-01)
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 ...
Estudo de arranjo granulométrico e condições operacionais de pré-filtração seguida de filtração lenta
(Universidade Federal de Santa MariaBrasilCiências AmbientaisUFSMPrograma de Pós-Graduação em Ciência e Tecnologia AmbientalUFSM Frederico Westphalen, 2021-06-22)
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 ...
