the aim of this study was to investigate the comparison between some seminal plasma parameters and age of the bull. concentrations of various biochemical parameters like fructose, glucose, total proteins, albumin and inorganic ions including na, k and cl ions of seminal plasma of breeding sahiwal bulls of different ageswere assessed. methods: 40sahiwal bullsdivided into 4 age groups.semen (2ml ...
the geopolitics of afghanistan after september 11, 2001, and its impact on iranian national security
abstract u.s. attack to afghanistan after 9/11 provided opportunities for us who tried to become the dominant power after collapse of ussr and bipolar world. thinkers like fukuyama believed american liberal democrats thought would be universally accepted without resistances. liberal democracy is the best and final model of governance; in this regard, united state has moral responsibilities for...
This paper analyzes the MHD flow and heat transfer of a pure fluid nanofluid through porous medium in vertical channel. The right half channel contains left nanofluid, which is immiscible with half. Channel walls are impermeable at constant temperatures. An external homogeneous magnetic field perpendicular to applied on Darcian approach used model medium. Relevant differential equations solved ...
let g=(v,e) be a graph with vertex set v and edge set e.for two vertices u,v of g ,the closed interval i[u,v] ,consists of u,v and all vertices lying in some u-v geodesic in g.if s is a set of vertices of g then i[s]is the union of all sets i[u,v]for u,v ? s. if i[s]=v(g) , then s is a geodetic set for g.the geodetic number g(g) is the minimum cardinality of geodetic set.the maximum cardinalit...
We review recent work on a new class of topological defects which possess a nonsymmetric core. They arise in scalar field theories with global symmetries, U(1) for domain walls and SU(2) for vortices, which are explicitly broken to Z2 and U(1) respectively. Both of the latter symmetries are spontaneously broken. For a particular range of parameters both types of defect solutions are shown to be...
The present research describes the performance of NiO NPs/Ag-clinoptilolite composite adsorbent for the removal of uranium (U(VI)) ions from drinking water of Dezful city-Iran. Prior to the experiment reactions, Na-clinoptilolite was chemically treated with NaCl, Silver ions (Ag+) and subsequently Nickel (NiO) NPs to prepare NiO NPs/Ag-clinoptilolite. The samples were characterized by SEM, AAS,...
We review our recent works on solitons in U(NC) gauge theories with NF(≥ NC) Higgs fields in the fundamental representation, which possess eight supercharges. The moduli matrix is proposed as a crucial tool to exhaust all BPS solutions, and to characterize all possible moduli parameters. Since vacua are in the Higgs phase, we find domain walls (kinks) and vortices as the only elementary soliton...

abstract because of the many geopolitical, geo economical and geo strategically potentials and communicational capabilities of eco region, members can expand the convergence and the integration in base of this organization that have important impact on members development and expanding peace in international and regional level. based on quality analyzing of library findings and experts interv...
in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...
