Sustaining environmental flows to preserve biodiversity of aquatic plant and animal species, as well as constancy of water for human communities, is essential in many river ecosystems. On the other hand, hydrological changes caused by the dam and its related environmental problems have provoked many concerns for hydrologists, ecologists and policymakers. Therefore, the main aim of this research...
به منظور ارزیابی عکس‌العمل ژنوتیپ‌های گندم نان به تنش رطوبتی، 21 ژنوتیپ پیشرفته گندم دیم به همراه ارقام شاهد آذر2 و الوند در تنش خشکی (دیم) و آبیاری تکمیلی (دو بار آبیاری ) در قالب طرح بلوک‌های کامل تصادفی با سه تکرار در سال زراعی 88-1387 در ایستگاه تحقیقات کشاورزی دیم مراغه مورد مطالعه قرار گرفتند. تجزیه واریانس مرکب نشان داد که بین دو شرایط متفاوت محیطی و ژنوتیپ‌های مورد مطالعه تفاوت معنی‌دار...

during last few years, three seasons of excavations at the ultan qalasi, one season of stratigraphy in nadir tepesi and a short season of survey in mughan steppe enriched our knowledge about the ancient landscape of the area. the mughan steppe is a geographically diverse region in the northwestern corner of the islamic republic of iran, defined at the north by the aras (araxes) river and includ...
In order to assess the relationship of grain yield and some of the agronomic traits recombinant inbred lines (RIL) population of bread wheat derived from the Roshan × Sabalan were used to detect the informative traits on grain yield as the suitable criteria for indirect selection and path coefficient analysis. Two hundred and sixty seven recombinant inbred lines with three control cultivars (Ro...
this study was conducted to evaluate seasonal concentrations of macro-minerals in serum or plasma of sheep under grazing conditions to establish mineral deficiencies and excesses over a two-seasonal grazing period (fall-winter and spring-summer corresponding to the rainy and dry seasons) according to variations of year, region and animal classes in sabalan, iran. in each flock, ten sheep (38-50...
Aims & Backgrounds: The Quaternary period is considered as the interval of climatic oscillations (glacial and interglacial) coupled with tectonic episodes. Therefore, tectonics and climate have simultaneously governed the evolution of Quaternary alluvial fans. Unraveling the tectonic and climatic factors under varied depositional systems is therefore the fundamental issue in understanding the e...
in this paper, fourteen mt stations along a profile perpendicular to the main geological structure were used in order to identify the geology of sabalan geothermal field including the extension of the surface cap-rock and clay-cap layers. the mt data collected between 1-8192 hz is of useful quality and provides good control on the surface layers in many areas. it means that reliable modeling sh...
summarythe explanation of the elastic, or velocity structure of the earth has long been a goal of the world’s seismologists. for the first few decades of seismological research, the investigation on velocity structure was restricted to the determination of one-dimensional models of the solid earth and of various regions within it. seismologists are currently obtaining three dimensional velocity...
this study was conducted to determine regression equations for the prediction metabolizable energy value corrected for zero nitrogen retention (amen) in 12 wheat cultivars (mahdavi, chamran, sabalan, sepahan, sivand, alamoot, sholeh, neishaboor, pishtaz, bahar, shiraz and shahpasand) cultured in alborz province of iran. chromic oxide marker bioassay was used to determine wheat cultivars nitroge...
