Biofiltration of hydrophobic and recalcitrant volatile organic compounds faces challenges, the bioaerosols sourced from biofiltration might cause secondary pollution. In this study, combination ultraviolet photodegradation biotrickling filtration (UV-BTF) was designed to treat gaseous cyclohexane, UV post-treatment (post-UV) further utilized for bioaerosol emissions management. Results showed t...

contact lens wearers are at great risk of developing microbial keratitis because of incorrect usages and unhygienic maintenance of contact lenses. therefore, the present study was planned to provide data that will be helpful in selecting the anti-microbial to cure microbial keratitis. one hundred bacterial isolates from conjunctiva of contact lenses wearer were isolated, identified and subjecte...

Human activity pollution has been shown to harm the environment, ecology, and health impacts. The polycyclic aromatic hydrocarbons (PAHs) produced by industries such as tannery, distillery, pulp paper, oil refineries are a major source of contaminant. PAHs found all across world, owing long-term human sources. PAHs' physico-chemical features, hydrophobicity electrochemical stability, contribute...

a r t i c l e i n f o Polarization curves from microbial fuel cells (MFCs) often show an unexpectedly large drop in voltage with increased current densities, leading to a phenomenon in the power density curve referred to as " power overshoot ". Linear sweep voltammetry (LSV, 1 mV s − 1) and variable external resistances (at fixed intervals of 20 min) over a single fed-batch cycle in an MFC both...

We introduce a computational framework termed OptReg that determines the optimal reaction activations/inhibitions and eliminations for targeted biochemical production. A reaction is deemed up- or downregulated if it is constrained to assume flux values significantly above or below its steady-state before the genetic manipulations. The developed framework is demonstrated by studying the overprod...

biofiltration of triethylamine (tea) vapor used as a catalyst in casting operations was evaluated in this study. the unit consisted of a 6-l three-stage biofilter containing a mixture of compost and wood chips (40:60 v/v) as the filter medium. seed microbial population from municipal activated sludge was acclimated for a period of three weeks prior to the actual experimental runs. in the startu...

background and objectives: the usepa has suggested faecal enterococci as the primary bacterial indicators. of more importance is their direct correlation with swimmer-associated gastroenteritis in recreation water quality monitoring. in contrast to other seawater bodies with 3.5% salinity, the recreational waters in the southern coast of the caspian sea possess its own salinity (about 1% w/v) a...

in rabbits, especially in some races, limb movement disorder called splay legs, are mostly unilateral or bilateral in front or hind legs at an early age. the severity ranges from mild to severe in this case. in breeding colony of albino dutch laboratory rabbits, the splay leg disorder has been observed over the years permanently.within the scope of this research, 1.5-2.5% of 700-750 number of c...

Axenic (GF) and holoxenic (CV) rats were given a semi-synthetic diet containing no fiber (0) or 10 p. 100 bran (B). The GFO, GFB, CVO and CVB groups were compared to assess the action of the flora and the bran. The bran diet did not change body growth, food intake or cecal water content. It caused only a slight decrease in the digestive utilization of the diet in the holoxenic rats and a declin...
