oxidative addition reactions of 1,4-diiodo-butane and 1,3-diiodo-propane with [ptme2(ph2phen)]; in which ph2phen=4,7-diphenyl-1,10-phenanthroline, were studied in different solvents such as acetone and benzene.oxidative addition reaction of [pt me2(ph2phen)] with i(ch2)4i and i(ch2)3i produced the [pt me2i(ch2)4(ph2phen)i] (1a) and [pt me2i(ch2)3(ph2phen)i] (1b).all the platinum (iv) products w...

Development of high yielded varieties is important to balance between production rates and grewing food needs of human population. For genetic analysis of yield and some important traits in oilseed rape (Brassica napus L.), We conducted line×tester analysis with ten lines and ten testers (three winter parents and seven spring parents). First generation hybrids as well as 20 parents (120 genotyp...

In order to evaluation of gain yield and yield components in spring barely genotypes under normal and drought stress in flowering stage and identifying drought tolerant genotypes, sixteen barely genotypes were investigated in two separately Randomized Complete Block Design with three replications in West Azerbaijan Agricultural and Natural Resources Research Center, Urmia, Iran in agronomic sea...

The results of diallel analysis of 7 parents and 21 F2 progenies of Burley tobacco cultivars, which were transplanted in 2002 as RCBD with 3 replications in the Tobacco Research Center, Rasht, Iran, showed significant genetic differences among genotypes and high GCA and SCA for most of the traits. Therefore the role of additive and non-additive (dominant) effects of genes on the formation of th...

To determine the relationships between agronomic and physiological characteristics of soybean, 30 soybean genotypes in factorial experiment based on a randomized complete block design were planted in Sari of Agricultural Sciences and Natural Resources University (SANRU). Correlation coefficients between traits showed positive and significant correlation between the considered traits and grain y...

this study aims to investigate value conflicts between mothers and their daughters among families and influential factors on this conflict in yazd city. this study adopted a survey method and a questionnaire was used that its validity through construct validity (factor analysis) and its reliability by cronbach alpha were measured. the population of this study consists of all yazdian families th...

in the new age, in regard to human success in education in the globalizing world, one can consider english proficiency and individual differences as two important issues. in efl settings, reading skill plays an important role in education. it seems that using multiple intelligences theory in efl classes which values individual differences by tapping different intelligences, can be rewarding. as...

Various strategies have been developed to reduce water consumption in rice cultivation, including rice cultivation in water-saturated soil, drying and wetting of the soil (periodic irrigation), and aerobic rice cultivation. In this study, in order to identify and grouping rice cultivars suitable for aerobic cultivation, 34 cultivars of native and improved rice cultivars were selected and eval...
