Colonoscopic evaluation is an important tool in the evaluation of ulcerative colitis (UC). UC is divided by disease extent into proctitis, proctosigmoiditis, left-sided colitis, and pan-colitis. In addition, a cecal or peri-appendiceal patch and backwash ileitis are associated with UC. The extent and behavior of UC has been characterized further using various indices and scoring systems; among ...

Close observation at a number of South African water treatment plants has shown that media losses during backwashing are excessive – much higher than anticipated. The only likely reasons for this phenomenon are either that insufficient freeboard was provided by the designer or that the mechanical behaviour of the media gradually changes after being placed in the filters. A number of media tests...

a bioreactor equipped with hollow fiber microfiltration membranes was applied for wastewater treatment. removal of chemical oxygen demand (cod) and biochemical oxygen demand (bod5) was investigated. the experimental setup consisted of influent and effluent tanks, and membrane modules using polyvinyl di–fluoride (pvdf) hollow fibers. the operation program included suction and backwash steps whic...
