Not all Warm Front measures lead to significant improvements in living conditions, but where they do, there is evidence of better physical as well as mental health. Our survey of

φ (Si, O ,Si) of 142.8 (5)°, a value close to those reported in the homologous phases; e.g. The resulting powder was then melted at 1423 K in a crucible made of quartz. Two

The chains consist exclusively of the two geometrically different molecules, alternately hydrogen bonded to each other via the Cl 2 CÐH group of one molecule.. with the OÐS(O)ÐPh of

A three-dimensional network of hydrogen bonds is observed in the crystal and H atoms of the guanidinium cations and water molecules are involved.. The phenylguanidinium cations show

The first plasmid-mediated resistance to quinolones was discovered in 1998 [11], in a clinical isolate of Klebsiella pneumoniae that could transfer low-level resistance

The displacement ellipsoids for both methyl groups correspond quite well to those anticipated for hindered rotors with a rather high potential barrier and threefold symmetry
