Ghar-e Boof, key archeological site in southern Zagros, is located at an altitude 905 m.a.s.l. Dasht-e Rostam Fars Province, Iran. On basis lithic artifacts radiocarbon luminesce...
چکیده سابقه و هدف: لیستریا مونوسیتوژنز یک باکتری گرم مثبت، پاتوژن داخل سلولی اختیاری و علت وقوع مسمومیت های غذایی و همچنین عامل بیماری های شدید در گروه های آسیب پذیر جامعه انسانی می باشد. روش استاندارد برای تشخیص این باکتری کشت میکروبی بوده که این روش بیشتر از 36 ساعت طول می کشد. لذا دست یابی به آزمونی که بتواند در هر شرایطی وجود این باکتری را در نمونه بالینی نشان دهنده، ارزشمند است .لیستریوزی...
Woody canopy cover is an essential variable to characterize and monitor vegetation health, carbon accumulation land–atmosphere exchange processes. Remote sensing-based global woody forest maps are available, yet with varying qualities. In arid semi-arid areas, existing products often underestimate the presence of due sparse bright soil background. Case studies on smaller regions have shown that...
BACKGROUND The Hajar Mountains of Oman and the United Arab Emirates (UAE) is the highest mountain range in Eastern Arabia. As a result of their old geological origin, geographical isolation, complex topography and local climate, these mountains provide an important refuge for endemic and relict species of plants and animals with strong Indo-Iranian affinities. Among vertebrates, the rock climbi...
Abstract Due to the growing need for hydrocarbons and limited conventional resources, paying attention unconventional oil gas resources is essential. The upper Jurassic-Lower Cretaceous in western southwestern Iran contains most crucial source rocks of Zagros sedimentary basin. One richest shaly Garau Formation. Owing geochemical geological characteristics, Formation, with Neocomian Coniacian a...
in this study, we investigate the further properties of quasi irresolute topological groupsdened in [20]. we show that if a group homomorphism f between quasi irresolute topologicalgroups is irresolute at eg, then f is irresolute on g. later we prove that in a semi-connectedquasi irresolute topological group (g; ; ), if v is any symmetric semi-open neighborhood ofeg, then g is generated by v...
flower morphology of ten fritillaria species of subgenera theresia and fritillaria growing wild in iran is studied using seventy morphological characters. qualitative and quantitative datasets separated taxa into subgenera, sectional and groups. three enigmatic species f. caucasica, f. zagrica (endemic to zagros mountains) and f. pinardii (recently reported from zagros mountains) appeared as cl...
