Flow injection analysis (FIA) has emerged as an increasingly used laboratory tool in chemical analysis. Employment of the technique for on-line sample treatment and on-line measurement in chemical process control is a growing trend. This article reviews the recent applications of FlA. Most papers refer to on-line sample treatment. Although FIA is very well suited to continuous on-line process m...
the aim of the present study was to characterize allergen-specific immunoglobulin e (ige) among children in fez region. eighty one children were recruited from the hospital university center of fez. all of them had completed a questionnaire before taking sera. the sera were used to measure total ige and specific data to proteins of egg's white (ewp), peanuts (pp) and gliadins (g). in last part,...
objective(s):the limited homing potential of bone-marrow-derived mesenchymal stem cells (bm-msc) is the key obstacle in msc-based therapy. it is believed that chemokines and chemokine receptor interactions play key roles in cellular processes associated with migration. meanwhile, mscs express a low level of distinct chemokine receptors and they even lose these receptors on their surface after a...
The ever-increasing human demand for safe and clean water is gradually pushing conventional water treatment technologies to their limits. It is now a popular perception that the solutions to the existing and future water challenges will hinge upon further developments in nanomaterial sciences. The concept of rational design emphasizes on 'design-for-purpose' and it necessitates a scientifically...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
considering the water scarcity in iran and the importance of environmental protection, it is approperiate to investigate the environmental management of siah-rud river. it is a small river being utilized as discharge channel by factories located in the vicinity of the river. the physico-chemical characteristics of river water at 10 different sampling locations 'along with coefficient of ae...
background; conventional chemical coagulation is considered as the old method to color and cod removal in textile effluent. electrocoagulation (ec) process is a robust method to achieve maximum removal. methods; this work was designed to compare the result of operational parameters including optimum ph and coagulant concentration for chemical coagulation with ferric chloride and alum. also, the...
background low-cost anaerobic sequencing batch reactor (asbr), which is widely used for controlling high-organic wastewater, is an effective method to remove chemical oxygen demand (cod). objectives the main objectives was evaluating the feasibility of using asbr in the treatment of synthetic dairy wastewater, determining its removal efficiency, and assessing the effect of temperature on operat...
activated sludge or extended aeration treatment involves a continous system where aerobic biological growths are mixed with waste water and then separated in a gravity clarifier. therefore, waste treatment system such as the activated sludge system depend on the activities of communities of living organism. in this study, an attempt was made on the indentification of the bacterial population in...
