Electrocoagulation has a long history as a water treatment technology having been employed to remove a wide range of pollutants. Inspite of its manifold applications the technique has never been accepted as a mainstream water treatment technology due to lack of a systematic approach to electrocoagulation reactor design, operation and the issue related to electrode dissolution over period of tim...

OBJECTIVE To evaluate the size of ovarian damage caused by ovarian drilling in polycystic ovary syndrome, the amount of inflicted damage was assessed for the most frequently used ovarian drilling techniques. DESIGN Experimental prospective design. SETTING University clinic. PATIENT(S) Six fresh bovine ovaries per technique. INTERVENTION(S) Carbon dioxide (CO(2)) laser, monopolar electro...

PURPOSE To evaluate the safety and efficacy of an embolotherapeutic technique that uses electrolytically detachable platinum coils and radio frequency (RF) energy to achieve rapid and distal occlusion of targeted vessels. METHODS In swine, branches of the ascending cervical artery and the hepatic artery measuring 1.5 mm or less were subjected to endovascular electrocoagulation. RF energy was ...

There are various techniques for removal of water hardness each with its own special advantages and disadvantages. Electrochemical or electrocoagulation method due to its simplicity has gained a great attention and is used for removal of various ions and organic matters. The aim of the present study was to investigate the efficiency of this technique in removal of water hardness under different...

Electrocoagulation of a plant extract and certain substances representative of selected classes of plant pigments, viz. chlorophyll, a carotenoid, a phenolic substance and a tannin, was performed in ethanol containing varying amounts of water (15-75%). The results showed that the extent and efficiency of coagulation of these substances tends to vary in a manner directly related to the water con...

BACKGROUND We have developed a single port access (SPA) surgical technique that allows for procedures to be done through a single umbilical port incision <20 mm in length. For a new approach to be universally beneficial, it needs to be easily learned and applied. METHODS Single port access abdominal procedures are performed through one umbilical incision where skin and soft tissue flaps are r...

Heavy metals pollution has become a more serious environmental problem in the last several decades as a result releasing toxic materials into the environment. Various techniques such as physical, chemical, biological, advanced oxidation and electrochemical processes were used for the treatment of domestic, industrial and agricultural effluents. The commonly used conventional biological treatmen...
