Cucumber is a warm season crop that suffers from chilling injury at temperatures below 10°C. In recent years, jasmonates have been used for reduction of chilling injuries in plants. An experiment was, therefore, conducted to test whether methyl jasmonate (MeJA) application at various concentrations (0, 0.05, 0.1 and 0.15 mM) through seed soaking or foliar spray would protect cucumber seedlings,...
In the mononuclear mixed-ligand title complex, [AgCl(C7H7NS)(C18H15P)2], the Ag(I) ion is four coordinated by one S atom of a benzene-carbo-thio-amide ligand, two P atoms of two tri-phenyl-phosphane ligands and one chloride ion, displaying a distorted tetra-hedral coordination geometry. In the crystal, pairs of N-H⋯Cl hydrogen bonds form inversion dimers. An intra-molecular N-H⋯Cl hydrogen bond...
The asymmetric unit of the title compound, C(8)H(9)N(2) (+)·C(8)H(5)O(4) (-), contains two independent ion pairs. In each 2-methyl-1H-benzimidazolium ion, an intra-molecular O-H⋯O bond forms an S(7) graph-set motif. In the crystal, the components are linked by N-H⋯O hydrogen bonds, forming chains along [210]. Further stabilization is provided by weak C-H⋯O hydrogen bonds.
The pairand three-proton interaction potentials for metal-phase hydrogen are calculated. Irreducible three-proton interactions are shown to be essential in the development of the metal hydrogen structure. Possible manifestations of the three-ion interactions in the structure of quickly quenched metallic systems are discussed. Existence of amorphous metals is related to manifestations of the thr...
1. The human gall bladder acidifies the bile. In this respect its action is similar to that of the gall bladders of lower animals, previously described by other workers. 2. The hydrogen ion concentration of gall bladder bile is increased considerably in cases of obstruction of the common or cystic ducts. The highest values were found following complete obstruction. 3. The occurrence of gall sto...
Arteriolar diameters and venular erythrocyte velocities in the small pial vessels on the surface of the cat brain were measured by TV methods during induced epileptic seizures through a cranial window. Grand mal seizures maximally dilated arterioles and increased venular erythrocyte velocity up to 400%. High positive correlation existed between changes in CSF hydrogen ion concentration and pial...
My answer to all these questions is: Use the concentration of titratable hydrogen ion in the extended extracellular fluid (at the actual oxygen saturation), ctHEcf, as the relevant measure of an overall metabolic acidosis or alkalosis, which may be due to several cooperative or counteractive pathophysiological processes. ctHEcf and SBE are numerically equal, with opposite sign, but it is the hy...
We report herein the synthesis of ¾ substituted benzene sulfonamides linked via phenyl ring to a benzothiazole moiety. The title compounds in the two series namely N-(4-(benzothiazole-2-yl) phenyl) 4- substituted benzene sulfonamides and N-(4-(benzothiazole-2-yl) phenyl) 3- substituted benzene sulfonamides were synthesized by condensing 2-(3/4-aminophenyl) benzothiazole with various...
