The kinetics and mechanism for degradation of omethoate (OMT) by catalytic ozonation with Fe(III)-loaded activated carbon (Fe@AC) were investigated in this study with focus on identification of degradation byproducts. The rate constants of OMT reacting with ozone and hydroxyl radical ((·)OH) were determined to be 0.04 and 5.3×10(8) M(-1) s(-1) at pH 7.5 and 20 °C, respectively. OMT was predomin...

BACKGROUND Cosmetic procedures are growing ever more common, and the use of soft tissue fillers is increasing. Practicing physicians need to be aware of the biological behavior of these products in tissue to enable them to respond to any safety concerns that their patients raise. OBJECTIVES To provide an overview of the metabolism of 1,4-butanediol diglycidyl ether (BDDE)-crosslinked hyaluron...

Microbial enhanced oil recovery (MEOR) is a technology that could potentially increase the tertiary recovery of oil from mature oil formations. However, the efficacy of this technology in fractional-wet systems is unknown, and the mechanisms involved in oil mobilization therefore need further investigation. Our MEOR strategy consists of the injection of ex situ produced metabolic byproducts pro...

Two levels of incorporating cattle tallow (CT) and agricultural or agro-industrial byproducts regional abundance were tested in the supplement to be compared with usual practice supplementation farm, using cover limitations base ration calves at end lactation. Using a completely randomized design three treatments, determine their effect on weight gain (WG), food intake, animal behavior cost sup...

Abstract Background Raw materials composed of easily assimilated monosaccharides have been employed as carbon source for production microbial lipids. Nevertheless, agro-industrial wastes rich in galactose-based carbohydrates not introduced feedstocks oleaginous yeasts. Results In this study, Aureobasidium namibiae A12 was found to efficiently accumulate lipid from soy molasses and whey powder c...

The effect of crystal size on VHP sugar colour was evaluated on a factory scale over the 1988/89 season at Sezela. Generally, smaller crystals produced lower sugar colour but the difference wasnot significant (at the 5% level) in the size range tested. Smallercrystals producedloweraffinated sugarcolourand the difference was significant at the 5% level. The mass of sugar in a full rail truck was...
