The tundra-taiga interface, or forest-tundra (lesotundra in Russian, and toundra forestière in French), corresponds to the subarctic zone where the closed boreal forest gradually becomes less dense and progressively breaks down into tree islands towards the treeless, Arctic tundra (1). The interface does not form a sharp limit of tree growth in the landscape but is instead a north-south transit...

X-ray powder diffraction assumes many roles in the analysis of pharmaceuticals. Pharmaceuticals, typically organic solids, exist in numerous solid forms that feature different physical and chemical properties. The vast majority of pharmaceuticals are administered as oral tablet dosage forms. In order for a drug molecule to be absorbed by the body, it must first dissolve. One of the most effecti...
متن کامل15 - 22 FT-IR Study
FT-IR spectra of liver tissue isolated from mice, Mus musculus, have been recorded in the region of 4000 – 400 cm-1 for normal, mercury treated and recovery phase. In this study, the total protein content was found to be decreased in the liver tissues after treatment with median-lethal dose of mercuric chloride. The marked fall in the level of bio-chemical constituent in the tissue due to metal...
متن کاملN-(Diphenylselenio)diphenylsulfimidium tetraphenylborate.
The title compound, C24H20NSSe+.C24H20B-, exhibits disorder (S/Se scrambling) of the chalcogen sites within the S-N-Se triad. Similar disorder was observed in the bromide salt [Aucott, Bailey, Elsegood, Gilby, Holmes, Kelly, Papageorgiou & Pedron-Haba (2004). New J. Chem. pp. 959-966]. The S-N and Se-N bond lengths are 1.6735 (15) and 1.8045 (14) A, respectively. Whereas the chalcogens in the b...
