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...
abstract previous studies on willingness to communicate (wtc) have shown the influence of many individual or situational factors on students’ tendency to engage in classroom communication, in which wtc has been viewed either at the trait-level or situational level. however, due to the complexity of the notion of willingness to communicate, the present study suggests that these two strands are ...
Shirbot (Barbus grypus) as a species with high potential for aquaculture development recently propagated artificially in South Iran Aquaculture Research Center to extend the species diversity in polyculture system. To provide an effective economic diet for this species 9 experimental diets containing three crude protein levels (250, 300, and 350 g kg -1) and three metabolizable energy levels ...
AIM To compare the total and organic mercury content in sea-fish samples from Croatia, where fishing occurs in a closed part of the Mediterranean Sea, and from other countries fishing mostly in the oceans. METHOD During 1997, we collected at the Zagreb fish market a total of 115 samples of fifteen kinds of fish including bathypelagic, pelagic and elasmobranch fish, caught in the wider coastal...

production, reproduction, management and economic parameters resulted from recordings of 5 flocks comprised of 720 heads of native goats during annual cycle of reproduction in transhumance, village and farming systems were employed to determine the performance of traits, cost-profit analysis as well as breeding objective. the overall mean for number of salable kid per goat in transhumance, vill...
In this study, the effect of experimental diets containing different levels of carbohydrate and niacin on growth indices, carcass composition and heamolymph biochemical parameters of juvenile whiteleg shrimp (Litopenaeus vannamei) were investigated for 45 days. Shrimp with mean initial weight of 5±0.33 g were reared in 300 liter tanks with 8 treatments. Feeding was performed 4 times a day using...
abstract this study investigates the teachers’ correction of students’ spoken errors of linguistic forms in efl classes, aiming at (a) examining the relationship between the learners’ proficiency level and the provision of corrective feedback types, (b) exploring the extent to which teachers’ use of different corrective feedback types is related to the immediate types of context in which err...
This study was carried out to investigate the supplemental effects of dietary garlic extract (GE) on growth performance of juvenile sterlet sturgeon (Acipenser ruthenus). The first experiment was designed to determine the optimum levels of garlic extract as growth promoter during 10 weeks. Three groups (two replicates/group) of 240 fish with mean body weight of 85 g were fed with diets containi...
