study of cohesive devices in the textbook of english for the students of apsychology by rastegarpour
this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Rapid phosphorus triester hydrolysis catalyzed by bimetallic tetrabenzimidazole complexes.
Bimetallic complexes based on the binucleating ligand N,N,N',N'-tetrakis[(2-benzimidazolyl)methyl]-2-hydroxy-1,3-diaminopropane (1L) and its new toluoyl ester derivative (2L) catalyze the hydrolysis of phosphorus triesters at ambient temperature with activities rivalling the fastest known systems.

Relief of procaspase inhibition enhances the potency of cancer chemotherapeutics Botham RC, Fan TM, Hergenrother PJ Manipulation of the apoptotic cascade is an effective and commonly employed strategy for the eradication of cancer cells. This work utilizes the small molecule PAC-1 to target the labile zinc pool, a physiological inhibitor of apoptosis. Labile zinc inhibits the conversion of proc...
متن کاملDNA-catalyzed hydrolysis of esters and aromatic amides.
We previously reported that DNA catalysts (deoxyribozymes) can hydrolyze DNA phosphodiester linkages, but DNA-catalyzed amide bond hydrolysis has been elusive. Here we used in vitro selection to identify DNA catalysts that hydrolyze ester linkages as well as DNA catalysts that hydrolyze aromatic amides, for which the leaving group is an aniline moiety. The aromatic amide-hydrolyzing deoxyribozy...
متن کاملPhase behavior of polyelectrolyte-surfactant complexes at planar surfaces.
We investigate theoretically the phase diagram of an insoluble charged surfactant monolayer in contact with a semidilute polyelectrolyte solution (of opposite charge). The polyelectrolytes are assumed to have long-range and attractive (electrostatic) interaction with the surfactant molecules. In addition, we introduce a short-range (chemical) interaction which is either attractive or repulsive....
