Odorless regioselctive ring opening of epoxides with S-alkylisothiouronium salts as masked thiols in water
(ARKAT USA INC, 2009)Opening of epoxides with various S-alkylisothiouronium salts as thiol equivalent in water has been carried out in excellent yield following an environmentally benign odorless reaction condition. Yields were excellent in ... -
On the Nature of Matter – 2500 Years of debate
(Indian Science News Association, 2008-07-01)The ancient Greeks left an extensive record of discussion regarding the nature of matter, and the debate has continued ever since. The ideas of atoms and forces were not especially popular, and they were only fairly recently ... -
ASCENT OF SAP
(Indian Science News Association, 2008-11-01)The enigmatic rise of water (sap) through the xylem of various plants has been a topic of active research and controversy for several decades. Various models like the vital theory models (viz. the pulsatile pumping model ... -
Digestion of the lambda cI Repressor with Various Serine Proteases and Correlation with Its Three Dimensional Structure
(ADENINE PRESS, 2008-12)Partial proteolysis of the lambda cl repressor has been carried Out systematically with trypsin. chymortrypsin, elastase, endoproteinase Glu-C, kallikrein, and thrombin. The cleavage sites have been determined by (i) ... -
Charge response of polyethylene terephthalate polymers (PET) to light and heavy nuclei
(PERGAMON-ELSEVIER SCIENCE LTD, 2008-08-01)A particular brand of common polymer film has been found to have a high detection threshold value of Z / β, when used as a solid state nuclear track detector to detect energetic ion beams. From the infra-red absorption ... -
Inter-Cellular Variation in DNA Content of Entamoeba histolytica Originates from Temporal and Spatial Uncoupling of Cytokinesis from the Nuclear Cycle
(PUBLIC LIBRARY SCIENCE, 2009-04)Accumulation of multiple copies of the genome in a single nucleus and several nuclei in a single cell has previously been noted in Entamoeba histolytica, contributing to the genetic heterogeneity of this unicellular ... -
