This study shows the benefits of using high molecular weight cationic polyacrylamide (PAM) in the purification of wastewater discharged from a wet scrubber in secondary lead smelter for reuse. The effect of temperature, pH, filtration pressure, polymer dose and different types of filtration fabrics on filtration rate (x), efficiency (ε) and quality of the produced water for recycling have bee...

The treatment of polluted industrial flow remains a relevant topic for the purpose sustainable development and improvement general state environment. removal particulate matter, especially their fine ultra-fine fractions, from gas flow, is an urgent task, but it poses many challenges demands purification technology. This paper presents results first stage research using newly developed cleaning...

In the past decade, pulse pressure has emerged as a strong predictor of cardiovascular morbidity and mortality. During aging, elevation of pulse pressure is a consequence of stiffening of the arterial wall. The relationship between pulse pressure and the renal aging process was studied in a cohort of 212 patients with never-treated isolated systolic hypertension. Glomerular filtration rate and ...

were estimated in 83 children with diabetes mellitus and compared with measures of glycaemic control, age, and duration of disease. Careful attention was paid to definition of normal values in age matched controls. The glomerular filtration rate was greater than normal, and correlated with duration of disease, but not with albumin excretion or blood pressure. Daytime albumin excretion correlate...

Rare cells such as circulating tumor and prenatal fetal can be captured by size-dependent filtration using a microfluidic device. Herein, we report method to release the with same device which consisted of microfabricated filter tapered holes. When cell containing flow passed through filter, could blocked filter. Afterward, reverse was applied cells. To increase efficiency capture release, hole...

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...

In this work, adaptive perfusion, a pressure-driven separation method based on the principle of tangential flow filtration (TFF) was developed for investigating rate and extent drug release from products containing particulates, such as emulsions, suspensions, liposomes, drug-protein complexes. The TFF filters were pre-conditioned with unique conditioning solutions processes to improve fiber re...
