Some properties of compounds in degrading bacteria are required for biodegradation of contaminants to higher performance. Those strains which have a high percentage of these features are more effective at biodegradation. The present experiments were designed to measure these parameters. In this study, measurement of cell surface hydrophobic-degrading bacteria was designed which oil was separate...

in this study the effect of different concentrations of some abiotic elicitors (salicylic acid, jasmonic acid, cadmium chloride and sodium chloride) with different incubation times (3, 6, 9 and 12) on azadiractin production and cell growth in the cell culture of the iranian native neem were investigated. cell growth rate was measured by changes in dry cell weight and it was used as a basis for ...

conclusion the open-cell stent is effective and its performance is higher than that obtained with the closed-cell stent for treating central vein stenosis or occlusion in hemodialysis patients. results for the open-cell stent group, 159 patients were diagnosed as central vein stenosis and 98 were occlusion. for the closed-cell stent group, 78 were stenosis and 66 were occlusion. there were two ...

stem cell therapy could have great potential for the treatment of a wide variety of diseases. stem cells might have the ability to differentiate into a widespread cell types, and to repopulate and revitalize the damaged cells with healthy tissue, and improve its performance. we provide here the evidence supporting the critical use of stem cell as a treatment in disease conditions existing with ...

in this research the simulation of an air independent proton exchange membrane fuel cell (pemfc) propulsion system was taken into consideration. the system consists of several parts including pem fuel cell stack, metal hydride and liquid oxygen (lox) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. the heat recovery...
