this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
background: despite the use of prophylactic chemotherapy and vaccination, coccidiosis is still one of the most devastating diseases in poultry industry. understanding the immune mechanism helps researchers to prevent this parasitic infection more effectively. objectives: the purpose of this study was to evaluate the antibody response in chickens, induced by a live attenuated vaccine (livacox q)...

The objectives of this study were to isolate Salmonella serovars from a large collection of samples obtained from pet birds in Tehran, Iran, and then to determine the serotypes and antimicrobial susceptibility profile of the isolates. Between October 2007 and Augu...
A deficiency of cytochrome c oxidase (COX) is associated with a number of diseases but details of the enzyme's mechanism of action especially the interaction with its substrate, ferrocytochrome c, remain unclear. It is known that the transfer of electrons from ferrocytochrome c to COX is facilitated by the formation of enzyme-substrate (ES) complexes which are stabilized by intermolecular salt ...
