The Behabad region is located within a tectono–sedimentary zone in southeast Yazd province, Central Iran. The tectonic activities have deformed and faulted the Mesozoic and Quaternary formations in this area. The faults in Kuhbanan and Behabad have played a key role in the evolution of geological events, mineralization, and the formation of Behabad–Kuhbanan horst. These faults have separated th...
Optimizing the operational parameters of borehole pattern in coal seam includes maximum amount gas to be drained with least drilling, investment, and drainage time. The main purpose this research is properly design C1 Tabas mine. In research, Comsol Multiphysics software was used for numerical modeling boreholes. According method diffusion methane a seam, reduction concentration released from b...
تخمین ساختار ثانویه پروتئین یکی از مهمترین مسائل در بیوانفورماتیک است. این تخمین معمولاً با روش های آزمایشگاهی انجام می گیرد که به دلیل هزینه بر و زمان بر بودن آن، یافتن راه حلی ارزانتر با زمان محاسبه معقول مورد توجه محققین قرار گرفته است. روش های رایانه ای گوناگون مانند شبکه های عصبی مصنوعی و مدل مارکف مخفی (hmm) ، راه حل های پیشنهادی برای تخمین ساختار ثانویه پروتئین هستند. اگرچه با استفاده از ...
objective: to find out the prevalence and relationship of anemia in reproductive age women in rural area of tabas, center of iran. iron deficiency anemia is the most common nutritional problem, affecting about 41.8% of pregnant and 30.2% of non-pregnant women worldwide. materials and methods: a cross-sectional study was conducted on the random sample of 382 reproductive age women in rural areas...
In this study, the isothermal reduction of iron oxide pellets, made of Iranian Chadormalo, Gole-gohar, and Sangan iron ores, was investigated in the temperature range of 900-1100°C. Tabas, Pabdana, Babnizoo, Karmozd, and Shahrood domestic coals were used as reductants. Parametric studies were performed and the effects of such factors as temperature, average particle size of iron ore and coal fi...
The trend of river discharge changes in arid and semi-arid regions is mostly decreasing and this trend can be influenced by climatic factors and rising temperatures in recent decades in these areas. This reduction in discharge could have a significant impact on the water storage of the Nahrin Dam and agriculture, industry and drinking water in Tabas City, which should be considered by experts. ...
Abstract This paper presents organic geochemical evidence pointing to the occurrence of wildfire events at Triassic–Jurassic boundary in Central Iran. The studied outcrop section (the Kamarmacheh Kuh section) is comprised Upper Triassic Nayband Formation which passes conformably into Lower Jurassic Ab-e-Haji with no sharp boundary. Organic petrographical studies reveal a higher concentration se...
in an attempt to reconstruct the paleoenvironments of deposition for the middle jurassic baghamshah formation, samples collected from six outcrop sections along the shotori swell were subjected to detailed geochemical analyses. bulk geochemical and biological marker data indicate a logical trend of the variation of organic input, salinity, and oxicity within baghamshah paleoenvironments across ...
