the crystal structure of the title schiff base complex is obtained by single-crystal x-ray diffraction data.the solid state structure determination reveals that the coordination geometry around the copper(ii) center istetrahedrally distorted square-planar. the crystal packing shows one dimensional infinite chains which arisesfrom the intermolecular interaction and stabilize the crystal packing.

human snake bitten poisoning is a serious threat in many tropical and subtropical countries such as iran. the best acceptable treatment of envenomated humans is antivenoms; however they have a series of economic and medical problems and need more improvements. in this study a combinatorial human immunoglobulin gene library against some of iranian snakes venoms was constructed. total rna prepare...

in this research, the effect of temperature on the physical and chemical behavior of nylon 66 tire cords in the range of 50-200°c and 16 h testing was studied. the results showed that heat treatment considerably reduced the breaking strength of cords. the intensity of reduction of breaking strength below 100°c and above 120°c was more pronounced than intermediate temperatures. the changes in pr...

achillea wilhelmsii have been used in folk remedies. the relaxant effects of the extractof a. wilhelmsii on tracheal chains of guinea pigs were examined. the relaxant effects offour cumulative concentrations of the extract, theophylline and saline were examined bytheir relaxant effects on precontracted tracheal chains of guinea pig by kcl (group 1), 10 μmmethacholine (group 2), incubated tissue...

This paper develops a two-stage model to consider a franchise/franchisee environment in which supply chains are simultaneously entering the untapped market to produce either identical or highly substitutable products and give franchise to franchisees. Customer demand is elastic, price dependent and customer utility function is based on Huff gravity rule model. The supply chains, in the first st...
