BACKGROUND Many case series studies have reported risk factors of infection with anaerobic bacteria, but few factor analysis studies have been conducted. OBJECTIVE We conducted a case-control study to identify the risk factors of anaerobic bacteremia. METHODS We compared a number of characteristics of patients with anaerobic bacteremia with those with aerobic bacteremia. Clinical informatio...
Surface and subsurface water collection in small seasonal rivers is very crucial, particularly in dry seasons. In this study a type of intake is introduced which acts as a river drainage network. An experimental model of the subsurface intake was constructed and the effective parameters such as upstream discharge, installation depth, and drain intervals were evaluated. The results showed that t...
the prospects of using the biostimulation and bioaugmentation treatment for the removal of the polychlorinated biphenyl (pcbs) from contaminated sediment collected from the sewage canal in the surroundings of a former pcb manufacturing plant in slovakia is described. the eleven bacterial strains isolated in our previous work from sewage strážsky canal sediments were able to aerobically degrade ...
Heavy metals and some organic substances which are drained into the aquatic environments and cannot be decomposed or eliminated will sink into sediments or find their way into different levels of food chain. Bioaccumulation is the process of continuous deposition and aggregation of these substances into the body tissue of living organisms. Mollusks are remarkably appropriate to be used as bio-i...
