Transesterification of beef tallow was investigated. The solubility of ethanol in beef tallow was much higher than that of methanol. At 100 °C the solubility of methanol was 19% (w/w). The solubility of ethanol in beef tallow reached 100% (w/w) at about 68 °C. For the distribution of methanol between beef tallow methyl esters (BTME) and glycerol, the percentage of total methanol in the glycerol...

Biodiesel production through transesterification results in a large quantity of crude glycerol as byproduct, the utilization which is technically and economically challenging. Because ability to efficiently process wet feedstocks, supercritical water gasification (SCWG) utilized this study convert into hydrogen-rich syngas. A significant challenge addressed decomposition routes different hetero...

BACKGROUND Acute kidney injury (AKI) is a serious clinical problem with high rate of mortality and morbidity. Currently used prophylactic and therapeutic strategies to address AKI are limited and warrant further studies. In the present study an attempt was made to investigate the effect of quinacrine, a phospholipase A2 inhibitor against glycerol induced AKI in rats. METHODS Adult female Wist...

1. The changes in the metabolite content in the isolated perfused rat liver and in the perfusion medium were measured after loading the liver with glycerol or dihydroxyacetone. 2. Glycerol was rapidly taken up by livers from fed and starved rats; glucose, lactate and pyruvate were discharged into the medium. The [lactate]/[pyruvate] ratio in the medium rose from 10 to 30 and in the tissue from ...

The physiological and metabolic effects of prophylactic treatment with osmolytes were investigated using twenty-four 2.5-yr-old Bos indicus steers. Animals were allocated to 1 of 4 treatment groups: 1) control, feed and water deprived for 48 h (n = 6); 2) transported, transported for 48 h (n = 6); 3) glycerol, dosed with glycerol (2 g/kg of BW) and then transported for 48 h (n = 6); and 4) beta...

Background: In-situ preservation of cauda epididymal spermatozoa at -10 degree centigrade with electrolyte free media for obtaining maximum functional gametes than preservation at 5 degree centigrade. Materials and Methods: Electrolyte free media prepared with soybean lecithin-glycerol, Coenzyme Q10 - glycerol and soybean lecithin - Coenzyme Q10- glycerol were inoculated separately into ligated...

in this work, the results concerning to the mean activity coefficient measurements for nacl in the (glycerol + water) system using the potentiometric method are reported. the potentiometric measurements were performed on the galvanic cells without liquid junction of the type: ag|agcl|nacl (m), glycerol (wt%), h2o (1 - wt)%|na-ise, in various mixed solvent systems containing 0, 5, 10, 20 and 30 ...

This paper investigates effects of different additives on morphology and subsequently, separation performance of asymmetric flat sheet Polyvinylidene fluoride (PVDF) membranes to separate CO2 using membrane contractor. Five different additives from different chemical families including Lithium chloride (salt), Polyethylene glycol 400 (polymer), glycerol (weak anti-solvents), methanol...

the possibility of applying membrane distillation to support the fermentation process was investigated. the capillary polypropylene membranes were assembled in the membrane modules. the studies were carried out using the standard solutions containing the compounds frequently occurring in the broths such as ethanol, citric, acetic and lactic acids, glycerol and 1,3-propanediol. the performance o...

Deprivation of available energy has been postulated to play a major role in the genesis of heart failure, and accumulating evidence points to the premise that changes in gene expression that alter energy metabolism weaken the heart muscle, reinforcing the logic of ameliorating energy substrates, and/or metabolism as a heart failure therapeutic. Reduced cardiac energy levels, in turn, influence ...
