in this study, the performance of electro-coagulation in combination with aluminum sacrificial anode, in removal of zinc and copper has been investigated. several parameters, such as pollutant concentration, ph, electrical potential, cod, turbidity and contact time were studied to achieve a higher removal capacity. variable concentrations (5-50-500 ppm) of zinc and copper solutions were prepare...

Blood coagulation is an extremely complicated and dynamic physiological process. Monitoring of blood coagulation is essential to predict the risk of hemorrhage and thrombosis during cardiac surgical procedures. In this study, a high throughput microfluidic chip has been developed for the investigation of the blood coagulation process under temperature and hematocrit variations. Electrical imped...

Immunoreactive beta-endorphin (beta-EP) in the ventricular fluid of six carcinomatous patients was measured using a specific radioimmunoassay. The subjects were undergoing a surgical procedure for relief of chronic intractable pain. This procedure involved the focal stimulation and coagulation of the posteromedial hypothalamus. Samples of ventricular fluid were collected before and after the st...

In this study, we have presented the case report of a 20 year old boy who suffered an electric injury shock, following which he showed peripapillary retinal opacification and increased retinal thickening that subsequently progressed to retinal atrophy. The fluorescein angiogram revealed normal retinal circulation, thus indicating thermal damage to retina without any compromise to retinal circul...

Limited available water resources have rendered wastewater reuse an important issue to specialists in most developed countries, today. The current study works on membrane filtration for treatment of industrial wastewater. By comparing the two methods of membrane bioreactor (MBR) and hybrid membrane electro bioreactor (MEBR) processes, it finds that earlier fouling in the membrane occurs in the ...

nowadays use of detergents and cleaners becomes one of the essential of human life's. since these materials enter to the sewage systems, due to the existing poly phosphate, reacts with water and gradually becomes into phosphate ions and cause too many environmental problems that always have considered environmentalists. this study examined three factors was investigated in the removal of p...

Argon plasma coagulation is increasingly used in endoscopic haemostasis. This case report illustrates the potential for thermal injury at a staple line remote from the area of argon plasma coagulation treatment as a result of electrical arcing. Increasing numbers of colorectal anastomosis and reconstruction procedures are now being performed using stapling techniques and the use of argon plasma...

Background: Highly-concentrated phosphate and nitrate anions from sugarcane wastewater are often discharged into public waters without standardized treatments. This study assessed the effects of electrical coagulation, initial pH and reaction time in the removal of phosphate and nitrate pollutants. Methods: We used aluminum electrodes to remove the pollutants at Hakhim Farabi Agricultural and ...
