The equilibrium molecular structure of the decasilsesquioxane, Si(10)O(15)H(10), in the gas phase has been determined by gas electron diffraction. Molecular dynamics calculations were used to give amplitudes of vibration and differences between interatomic distances in the equilibrium structure and the vibrationally averaged distances that are given directly by the diffraction data. The molecul...
در این تحقیق، تنوع ژنتیکی جمعیت آرتمیا اورمیانا و آرتمیا فرانسیسکانا ی موجود در ایران با استفاده از 5 جفت آغازگر ریزماهواره ای (af-b105tail، af-a136، apdq03tail، apdq04tail و apdq05tail) ویژه ی آرتمیا فرانسیسکانا و آرتمیا پارتنوژنتیکا بررسی شد. از 50 سیست آرتمیا ی هر یک از این دو جمعیت به صورت انفرادی dna با روش گلوله ی داغ استخراج شد. با استفاده از آغازگر ها ی پنج گانه و از طریق واکنش زنجیره ا...
We describe conditions on non-gradient drift diffusion Fokker-Planck equations for its solutions to converge to equilibrium with a uniform exponential rate in Wasserstein distance. This asymptotic behaviour is related to a functional inequality, which links the distance with its dissipation and ensures a spectral gap in Wasserstein distance. We give practical criteria for this inequality and co...
We introduce a game-theoretic model for network formation inspired by earlier stochastic models that mix localized and long-distance connectivity. In this model, players may purchase edges at distance d at a cost of d, and wish to minimize the sum of their edge purchases and their average distance to other players. In this model, we show there is a striking “small world” threshold phenomenon: i...
this study compares diversity patterns of five microsatellite (ssr) markers in two iranian native horse populations (turkoman sahra and turkoman jergelan) to infer relationships between them and to compare levels of their polymorphism for use in conservation efforts. two populations across microsatellite loci had significant deviations from hardy-weinberg equilibrium. average number of alleles ...
پسماند چوبی درشت ) coarse woody debris ( یکی از اجزای مهم اکوسیستم جنگل است که نقش مهمی در فرآیندهای این اکوسیستم ایفا میکند. طی دهه اخیر توجه فراوانی به این جزء مهم بومسازگان توسط بوم- شناسان و جنگلشناسان شده است و روشهایی برای نمونهبرداری این جزء مهم اکوسیستم معرفی شده که همگی قطعات cwd را با احتمال نابرابر به عنوان نمونه انتخاب می نمایند. pds ( perpendicular distance sampling ،) dls ( dis...
Oxynoemacheilu sangorae is an endemic freshwater fish of Iran. In the present study, six microsatellite markers were used to investigate population structure of stone loach (Oxynoemacheilusangorae) in gheshlagh (Kurdistan), Sefidbarg and Gamasiab (Kermanshah) rivers. All of the applied loci showed polymorphism. The average numbers of allele and observed heterozygosity were 14.33 and 0.82 respec...
Background: Interaction is considered a necessary, and integral part in all forms of distance learning and web -based learning environments. That how much technologies can support and help interactions is one of the most important issues that should be considered in the web-based environment. These interactions seek to engage students with other students, teachers and also non-human contex...
In modern programmes of animal breeding, the polymorphisms of the milk proteins can be used as marker systems. Beta-Lactoglobulin is the major milk whey protein in the ruminants. The BLG coding gene located on ovine chromosome 3. This protein, synthesis in the mammary glands during pregnancy and the lactation stages. Studies have indicated that this protein is polymorphic in the many breeds of ...
