background: domestic and industrial wastewaters are mostly treated by biological process such as activated sludge, aerobic pond, and anaerobic treatment. this study focuses on characterizing the quality of sewage sludge in the sultanate of oman chosen from three industrial sewage treatment plants (stps): rusayl industrial estate (rsl.ie); sohar industrial estate (sie); and raysut industrial est...
The use of reclaimed asphalt pavement (RAP) and/or recycled shingles (RAS) in the mixtures is a common practice U.S.A. However, there controversy to date on how RAP/RAS interact with virgin binders (VABs) mixtures. For containing RAP/RAS, aged RAP and air-blown RAS alter performances extracted (EABs). Thus, rheological properties EABs from these require more investigation. focus this paper was ...
The recirculating aquaculture system (RAS) is a cultivation that minimizes water changes and can optimize high stocking densities (SD). purpose of this study was to determine the effect nursery culture in density with RAS on survival rate (SR), specific growth (SGR), relative length (LR), weight gain (WG), (LG)and feed utility efficiency (FUE) juvenile catfish. used completely randomized design...
The role of three major Ras downstream effector pathways in the induction of mammary cancer was studied using an in situ mammary ductal gene delivery model. Replication-defective retroviral vectors were used to infect endogenous rat mammary epithelial cells with three individual Ras effector loop mutants, each of which transduces its signal through a different Ras effector pathway (Raf, PI3K or...
E-RAS is a member of the RAS family specifically expressed in embryonic stem cells, gastric tumors, and hepatic stellate cells. Unlike classical RAS isoforms (H-, N-, and K-RAS4B), E-RAS has, in addition to striking and remarkable sequence deviations, an extended 38-amino acid-long unique N-terminal region with still unknown functions. We investigated the molecular mechanism of E-RAS regulation...
Despite the fact that there are wastewater treatment plants (WWTPs) currently operational across Iran and great advances have been made in this area, there are still problems in the design, construction, and operation of WWTPs with large nonlinear systems, varying flow rates, and pollution charges. The objective of this study was to investigate the effect of operating parameters including the r...
Introduction: Recurrent aphthous stomatitis (RAS) is defined by recurring ulcers restricted to oral mucosa in the patients with no other signs of systemic disease. The purpose of this study was to evaluate the salivary level of interferon gamma in patients with RAS. Methods: In this case-control study, 30 patients with RAS (in Recurrence and recovery period) in the experimental and 25 healthy ...
Abstract : Reovirus (respiratory enteric orphan virus), a naturally occurring benign human pathogen, has an inherent ability to target transformed and cancerous cells and cause their lysis, while leaving non-transformed cells relatively unaffected. The efficiency of this innate oncolytic activity of reovirus correlates with expression of the ras oncogene. Cells expressing ac...
