Three phase partitioning, a method generally used for protein separation, has been evaluated for extraction of oil from soybean. 82% oil was extracted within 1 h using this process which required simultaneous addition of t-butanol (1:1, v/v) and 30% ammonium sulphate to the soybean slurry.

Caloric effects are currently under intense study due to the prospect of environment-friendly cooling applications. Most of the research is centred on large magnetocaloric effects and large electrocaloric effects, but the former require large magnetic fields that are challenging to generate economically and the latter require large electric fields that can only be applied without breakdown in t...

Sixteen Bonsmara calves (4 males, 12 females) between 10 and 18 months of age were blocked according to age and sex and randomly assigned to 2 groups. They were offered licks containing bone meal and salt (50:50 ratio) (control) and bone meal and ammonium sulphate (NH4SO4) at 1.25, 2.5, 5, 10, 15, and 18% (treatment) to evaluate the effects of dietary anions on bone phosphate (P) concentration....

Rates of oxygen uptake, sulphate reduction, carbon dioxide production, ammonium turnover, nitrogen fixation and denitrification were measured in sediments in a transect across a mangrove swamp in Jamaica. Carbon and nitrogen mineralisation increased as the transect entered the mangrove, indicating a greater availability of organic matter, probably by root excretion. Time course measurements of ...

The serum of a case of hyperglobulinaemia with negative thymol and zinc sulphate turbidity reactions was studied. The serum when added to pathological sera with high turbidity values brought about a marked reduction in the original turbidity values. Also, the serum did not give the usual copper proteinate precipitate when added to copper sulphate solutions. The anomalous protein fraction respon...

nanocrystalline zinc oxide (zno) powders with different morphology have been successfully synthesized by using different surfactants such as cetyl trimethyl ammonium bromide (ctab), sodium dodecyl sulphate (sds), and tri ethanol amine (tea) via hydrothermal method. the products were characterized by means of powder x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electr...

Wheat bran is one of the most used agricultural residues for enzyme synthesis. It has a high organic content; thus, it causes environmental pollution. In this study, wheat was selected as carbon source and supplemented with yeast extract ammonium sulphate. Endopectinase pectin lyase production by Bacillus pumilus performed in batch system. RSM applied to examine effects bran, sulphate concentra...
