In this paper operational matrix of Bernstein Polynomials (BPs) is used to solve Bratu equation. This nonlinear equation appears in the particular elecotrospun nanofibers fabrication process framework. Elecotrospun organic nanofibers have been used for a large variety of filtration applications such as in non-woven and filtration industries. By using operational matrix of fractional integration...

background: water filtration units have been faced problems in water turbidity removal related to their media, which is determined by qualitative indices. moreover, current qualitative indices such as turbidity and escaping particle number could not precisely determine the efficiency of the media in water filtration, so defining new indices is essential. in this study, the efficiency of anthrac...

the purposes of this research have been to determine the wastewater quality of a typical railroad repair workshop and to find a way to reduce the concentrations of present contaminants especially oil and grease. the mean concentrations of oil, cod and ss in the wastewater studied were 287.69, 775.85 and 28723, respectively with average daily discharge to be 30-35 m3. three successive treatment ...

conclusions functional renal impairment in diseases caused by hcv was more important than in diseases caused by hbv. the egfr was statistically lower in cirrhosis secondary to hcv than in hcv chronic hepatitis. results hbv chronic hepatitis, hcv chronic hepatitis, and cirrhosis secondary to these viruses were associated with a reduction of the gfr. the egfr was higher in patients with hbv chron...

conclusions our study shows a relationship between cimt and renal parameters, including egfr and albuminuria. this study confirms the importance of intensive examinations for early detection of atherosclerosis and treatment of risk factors. patients and methods this cross-sectional study was included 205 patients with type 2 diabetes mellitus (t2dm). we recorded clinical and biochemical data su...

background: in this study, the early effects of percutaneous nephrolithotomy (pcnl) on glomerular filtration rate (gfr) was assessed in different postoperative times and likewise, we determined the correlation of different variables with significant postoperative gfr drop  after pcnl. m aterials and methods: patient records of 486 cases that had undergone pcnl from january 2010 to october 2011 ...
