in the  present study, after investigating the theoretical bases and results of previous  researches and identifying the most important indicators and sub-indicators of human resource management affecting organizational performance, weighting and ranking the indicators were performed using the questionnaire (first) and applying the fuzzy ahp technique, in which the highest ranks were allocated ...

the insertion of an olefinic c=c bond into a metal-carbon bond is of potential interest as a preparativeroute to new products and as results of c-c coupling reactions to organic compounds. the allyl compoundsof mg, react with an olefin by inversion of the allyl group via a six center transition state. these precyclicreactions may be one of the most important classes of organic reactions. the re...

cryptococcosis has become the fourth leading life-threatening opportunistic infection in patients with aids, but also occurs in non-aids patients. in view of the increasing numbers of infection during last decade in iran, use of rapid, sensitive and specific test for diagnosis of cryptococcal disease has become important than ever. we aimed to produce the reagents for latex cryptococcal antigen...

INTRODUCTION Trifluoroacetic acid (TFA) is commonly used in the manufacturing process to release synthesized peptides from solid-phase resins. TFA or acetate is also used during reversed-phase HPLC purification of peptides. TFA is manufactured using acetate and fluoride as precursors, and residual levels of these compounds may be present whenever TFA is used. Residual TFA, fluoride, and, to a m...

Aliphatic ,w-dibromides can be converted to the corresponding c,w-di—Grignard reagents; for those members carrying less than four carbon atoms between the functions, special procedures are required. The synthesis, structure and applications of the di-Grignard reagents are discussed; particular emphasis is placed on the structures of the corresponding cyclic dialkylmagnesiums, and on the use of ...
