Spermicidal activity of some halides.
Though most of the metallic ions are spermicidal in action, the present investigation emphasises the spermicidal activity of anions. Among the inorganic compounds screened at 4 concentrations (0.01%, 0.1%, 1% and 5%) halides are mainly spermicidal, except NaCl, KCl & CsCl which are spermiostatic; sulphates and nitrates are mainly spermiostatic except ZnSO4 at 1% concentration and above; CuSO4, ...
متن کامل2-Carbamylpyridinium tetrachloridoferrate(III)
The title compound, (C(6)H(7)N(2)O)[FeCl(4)], contains two carbamylpyridinium (picolinamidinium) cations, which are linked into chains by N(+)-H⋯O hydrogen bonds formed between protonated pyridyl N atoms and carbonyl groups. Tetra-chloridoferrate(III) anions lie between these chains, accepting N-H⋯Cl hydrogen bonds from both H atoms of the picolinamidium -NH(2) group.
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولAmino Acid and vitamin requirements of several bacteroides strains.
Nutritional studies were performed on nine Bacteroides strains, by use of the methodology and media of anaerobic rumen microbiology. Ristella perfoetens CCI required l-arginine hydrochloride, l-tryptophan, l-leucine, l-histidine hydrochloride, l-cysteine hydrochloride, dl-valine, dl-tyrosine, and the vitamin calcium-d-pantothenate, since scant turbidity developed in media without these nutrient...
