run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

Sustainable diets represent a critical policy leverage realistic opportunity to reduce the environmental of agro-food while improving human health at same time. Eating out increasingly common habit for many consumers and, by offering sustainable dishes, catering companies can play central role. To do thi...
رشد فیزیکی در بسیاری از شهرهای کشورها به دلیل عدم وجود برنامه¬ریزی دقیق و مطالعه و بررسی اراضی جهت توسعه شهر، باعث شده است تا شهرها بستر فیزیکی خود را بر روی اراضی نامناسب از نقطه نظر عوامل طبیعی و غیرطبیعی و یا بر روی اراضی مناسب کشاورزی و فضاهای سبز پیرامون شهر گسترش دهند.در تحقیق حاضرکه حوزه استحفاظی شهر کرج در طی دوره زمانی (1365-1390) می باشدابتدا نقشه کاربری اراضی از تصاویر ماهواره¬ای تهی...
Abstract Mountainous rural areas are vulnerable to inappropriate land management, which is particularly visible in the Polish Carpathians. This paper attempts diagnose causes and effects of spatial chaos this area, using DPSIR method. The Three Questions method was used assist analysing disorder context violating sustainable development. analysis demonstrated that were mainly legal historical o...
introduction average per-capita renewable water of iran is decreasing strongly. in near future water wars in the middle east are predictable. exploitation of land resource has the most significant impact on wetlands. wetlands degradation is the serious warning to unsustainable development. despite that the lake urmia is recorded in conservation lists as iranian national parks, ramsar sites and ...
Tourism activities generally have a ∩-type lock on the level of tourism ecological security in an area, but when applied to border areas China, there are certain specificities spatial evolution (TES) compared traditional findings. This paper measures China’s from 2009 2020 by using DPSIR model with SBM-DEA and analyzes differences, evolutionary characteristics, driving factors Pearson’s correla...
