Lynch, G.L., Berger, L.L., Fahey, G.C., Jr. and Baker, E.C., 1986. Effects of isopropyl alcohol treatment of soya bean meal on nitrogen utilization by ruminants. Anim. Feed Sci. Technol., 14: 127-137. Soya bean meal (SBM) treated with isopropyl alcohol (IPA) or n-propyl alcohol (NPA) was used to study effects of alcohol treatments on SBM nitrogen (N) utilizatinn by ruminants. The IPA treatments...

In this study, organic-mineral hybrid silica coating was prepared by sol-gel process, in order to investigate the effect of Dimethyl octadecyl amin propyl group on TMOS wettability. The sol solutions were prepared at room temperature by hydrolysis and condensation of tetra methoxysilane (TMOS) diluted in methanol as solvent and in the presence of acetic acid as a catalyst and dimethylacetaldehy...

Substitution effects are probed for novel N-heterocyclic stannylenes (NHSns), including 1,4-di(R)-tetrazole-5-stannylenes (1R), and 1,3-di(R)-tetrazole-5-stannylenes (2R), using B3LYP/6-311++G** level of theory. Nucleophilicity, multiplicity, and stability of 1R and 2R are calculated; with R = H, methyl, ethyl, i-propyl, t-butyl, Ph, OH, methoxy, NO2, CN and CF3. Asymmetric 2H appears more nucl...

The phosphorylated intermediate in the (Na + K)-activated adenosine triphosphatase (Na-K ATPase) has been characterized as an L-glutamyl-gamma-phosphate residue in the enzyme. This has been accomplished by digestion of the phosphorylated and nonphosphorylated forms of the enzyme with pepsin, reaction of the pepsin digests with [2,3-(3)H]N-(n-propyl)hydroxylmine, further digestion of the derivat...

The zwitterionic title compound, C23H42N2O2S·4H2O, crystallized as a tetrahydrate from a solution of N-[(2,4,6-triiso-propyl-phen-yl)sulfon-yl]aziridine in tri-ethyl-amine, diethyl ether and pentane in the presence of moist air. It is formed by a nucleophillic ring-opening that is assumed to be reversible. The mol-ecular structure shows a major disorder of the triiso-propyl-phenyl group over tw...

X-ray structures of five bis(N — R-salicylaldiminato)zinc(II) complexes with R — ethyl, «-propyl, /-propyl, «-butyl and 4-thia-rc-hexyl were determined. The N202 coordination geometry is in all cases gwas/-tetrahedral with the dihedral angle between the planes of the two chelate rings ranging from 84 to 89°. Bond lengths and angles in the coordination sphere are not affected by the nature of R ...
