during field work in western regions of the iranian plateau in the zagros mountains in september 2010, a single specimen belonging to the genus and subgenus eremias fitzinger, 1834 was collected from the protected area of bijar (at about 1619 m elevation) in north of the city of bijar, kurdistan province, western iran (47°, 34’ e; 36°, 00’ n).
Bioavailable Sr and detrital Nd isotopes are important tools for archaeological provenance. To apply provenance, regional isotope databases baselines generally needed. For the vast Silk Road regions of Mesopotamia, Iran, Central Asia, detailed isotopic distribution patterns essential determining provenance may not become available in short term due to severe deficiency data. In present work, we...
Solid propellant burning rate is highly dependent on the pressure, so that the combustion duration propellant rocket engines, combustion vibration leads to considerable changes in pressure. This could lead to an explosion in rocket engines. The best case is propellant combustion independent of pressure. Ballistic modifiers added to propellant formulation for reduce pressure sensitivity and re...
Just over 5,000 years ago, the earliest cities flourished in Mesopotamia and western Iran. One explanation that has been considered is that making these areas with their seasonal alternations of flooding and drought amenable to agriculture required a complex infrastructure for water retention and irrigation. Thus, only a critical mass of workforce and a certain level of organisation could make ...
La naissance de l’agriculture à l’est du Croissant Fertile, sur le plateau Iranien et jusqu’en Asie centrale en Sud, est relativement mal connue. L’aire concernée vaste les données archéologiques liées cette période, Néolithique, y sont extrêmement limitées. plupart des chercheurs s’accordent penser que la pratique domestication plantes animaux fut introduite depuis l’Asie Sud-Ouest, au même ti...
this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...
BACKGROUND Ability of athletes in speed or endurance contests somehow is determined by inherited muscle fiber types. One of the important genes involved in sport genetics is ACTN3 that is located on chromosome 11q13-q14 and encodes α-actinin-3, which belongs to highly conserved family of α-actinin proteins. Genetic analysis of α-actinin-3 gene has showed a polymorphism R577X (rs1815739), which ...
