wastewater from molasses processing contains a large amount of coloured substances that give a recalcitrant dark brown colour and high organic load to the effluent. photocatalytic decolourization of molasses wastewater was performed using titanium dioxide catalyst coated on the surface of south african natural zeolite using the solid-solid dispersion method. addition of hydrogen peroxide as an ...

Chylomicron remnants are removed intact by isolated perfused rat livers and their lipid components are metabolized by the liver (Biochim. Biophys. Acta 488: 464, 1977). The present study provides quantitative information regarding these processes. When the lipoprotein concentration of the perfusate was constant, the removal of chylomicron remnants increases lineraly for 17 min. The rate of remn...

In this study, performance evaluation for the gas-phase o-xylene removal using a xylene-acclimated biotrickling filter (BTF) was conducted. Substrate interactions during aerobic biodegradation of three poorly soluble compounds, both individually and in paired mixtures (namely, o-xylene and ethyl acetate, o-xylene and dichloromethane, which are common solvents used by pharmaceutical industry), w...

In PCS networks, new calls to a portable may be lost due to incorrect location information (due to either data corruption or outdated records) in the home location register mobility database. Such database failures can be recovered through the portable's registration when it initiates a call, through required registration (or deregistration for some systems) as it crosses the location area boun...

Two experiments were conducted to assess the effect of buck exposure to synchronize estrus in mature and pre-pubertal norgestomet-treated crossbred (criolloxdairy breeds) goats. In experiment 1, 100 mature goats (25 per group) under range conditions were either teased at 48 or 24h before Sincromate-B (SMB; 9 days treatment of 2mg norgestomet) implant withdrawal. A third group was exposed to buc...

A monitoring campaign in a horizontal subsurface flow constructed wetland under the influence of transient loads of flow-rate, organic matter, nitrogen and suspended solids showed an irregular removal of COD and TSS and lower both removal efficiencies and mass removal rates than the ones observed in other studies for similar operating conditions. This circumstance is associated to the presence ...
