The chiral two-pion exchange component of the long-range pp interaction is studied in an energy-dependent partial-wave analysis. We demonstrate its presence and importance, and determine the chiral parameters c i (i = 1, 3, 4). The values agree well with those obtained from pion-nucleon amplitudes.
The title compound, [Cu2(C6)H12N4O2)(ClO4)2(C11H6N2O)2].-2C11H6N2O, contains a dinuclear copper(II) complex which lies about a twofold axis at the mid-point of the C-C bond of the oxamide ligand that bridges the two Cu(II) atoms. The Cu...Cu distance is 5.215 (2) A and the Cu atoms have distorted octahedral coordination geometry. Intramolecular N-H...O and N-H...N hydrogen bonds and intermolecu...
Synaptic activity promotes resistance to diverse apoptotic insults, the mechanism behind which is incompletely understood. We show here that a coordinated downregulation of core components of the intrinsic apoptosis pathway by neuronal activity forms a key part of the underlying mechanism. Activity-dependent protection against apoptotic insults is associated with inhibition of cytochrome c rele...
Abstract A boron trifluoride catalysed reaction of coplanar 9-(phenylethynyl)-9H-fluoren-9-ols with various 2-aminobenzamides affords a number highly functionalized, conjugated (Z)-2-((2-(9H-fluoren-9-ylidene)-1-phenylethylidene)amino) benzamides in excellent yield. The the presence N-bromosuccinimide (E)-5-bromo-2-((2-bromo-2-(9H-fluoren-9-ylidene)-1-phenylethylidene)amino)benzamides very go...
background: this study aimed to design a new mouse and evaluate some of its functional parameters. the prototype of an ergonomic mouse was made according to design principles. methods: the study was conducted from 2011 to 2013 in the department of ergonomics in shiraz university of medical science. functional parameters including movement time (mt) and error rate of the new mouse were evaluated...
in this research, a new technetium-99m generator has been developed with addition of cerium oxide to alumina column. the adsorption behaviors of 99mo in the form of molybdate and 99mtc in the form of pertechnetate on ceo2/al2o3 was investigated and showed that the adsorption capacity of molybdate on this generator is higher than usual generator using al2o3. ceric ions were selected as an addit...
