a series of transition metal complexes with two thiosemicarbazide schiff bases, 1-(4-dimethylaminobenzyl- idene)thiosemicarbazide (abtsc) and 1-(2-pyridincarboxyl-idene) thiosemicarbazide (tcts) were synthesized with co(ii), ni(ii), zn(ii), cd(ii) and ag(i) salts (chloride and acetate). these complexes were characterized by different methods including proton nuclear magnetic resonance (1hnmr), ...

in this paper, our focus of attention is the proper propagationof fuzzy degrees in determinization of $nondeterministic$ $fuzzy$$finite$ $tree$ $automata$ (nffta). initially, two determinizationmethods are introduced which have some limitations (one inbehavior preserving and other in type of fuzzy operations). inorder to eliminate these limitations and increasing theefficiency of ffta, we defin...

this survey is conducted with the purpose of studying factors effective in vitality of residential complexes. this is an important subject because through recognition of the reciprocal relation between human being and environment -as far as vitality is concerned- various attitudes and approaches can be recognized and on the other hand, for the purpose of explaining the concept of vitality in th...

human serum albumin (hsa) is an abundant, multifunctional and nonglycosylated negatively charged plasma protein. hsa ascribed ligand-binding and transport properties, antioxidant functions and enzymatic activities. in the present study, the interaction and side effects of a new designed anti-cancer compound (1,10-phenanthroline butyl dithiocarbamato palladium(ii) nitrate) on hsa have been inves...

the reaction between ni(ii), co(ii), cr(iii) bitrates, ni(ii) chloride and ambidentate a-keto ylide benzoylmethylenetriphenylphosphine (bppy) resulted in isolation of [ni(bppy)2](no3)2.2h2o, [ni(bppy)2]cl2, [co(bppy)2](no3)2 and [cr(bppy)3](no3)3; 2h2o. the compounds were characterized by elemental analyses and infrared 1hnmr spectroscopy, molar conductivity in solution and molecular weight mea...

tabriz petrochemical complex is located in northwest of iran and west of tabriz oil refinery and mostly produces raw plastics. in this study the implementation of reduction of hazardous waste contact in this complex with special emphasis on personal protective equipment (ppe) is discussed. accordingly different hazards threatening personnel, indoor and outdoor environment were determined. in or...

pseudo ricci symmetric real hypersurfaces of a complex projective space are classified and it is proved that there are no pseudo ricci symmetric real hypersurfaces of the complex projective space cpn for which the vector field ξ from the almost contact metric structure (φ, ξ, η, g) is a principal curvature vector field.
