in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...
For the production of high-performance polyethylene fibers and tapes by ultra drawing, using solid-state processing disentangled nascent ultra-high molecular weight (UHMWPE), maximum draw ratio is an important design parameter, as it determines degree chain alignment and, therewith, properties final product. It would, therefore, be advantageous to have a fast scanning method estimate drawabilit...
a frame semantic approach to the study of translating cultural scripts in salingers franny and zooey
the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...
the present research was an attempt to see how quranic lexical collocations were translated into english by two professional translators namely, abdullah yusuf(2005), and muhammad s. shakir(2012). the study attempted qualitatively to shed light on how translators dealt with quranic lexical collocations when transferring them to the target language based on the newmark(1988) model , and quantit...
به دلیل آن که استخراج مدل ریاضی از فرآیندهای صنعتی، دارای پیچیدگی های فراوانی است، مدل سازی بر اساس داده های ورودی و خروجی مورد استقبال بیشتری قرار گرفته است. از طرفی توجه به اصل سادگی، منجر به استفاده از ساختار مدل های چندگانه شده است. از این رو، در این پایان نامه سیستم تشخیص عیب مبتنی بر مدل های چندگانه مدنظر قرار گرفت. با استفاده از شناساگر عصبی-فازیِ محلی-خطی، بانک های مدل برای تمامیِ شرایط س...
To ascertain the potential of various leguminous biomass such as L. leucocephala, C. proliferus, P. alba and S. sesban, both energetic a source high added value products, pyrolytic behaviour was studied at different heating rates by using analytical method thermogravimetric (TG), isoconversional Kissinger-Akahira-Sunose (KAS), determination some thermodynamic parameters pyrolysis-gas chromatogr...
در سال‌های اخیر، ایروژل‌های کربنی توجه ویژه‌ای را به خود اختصاص داده‌اند. این دسته مواد برپایه کربن در دمای نسبتاً کم (حدود 400 درجه سلسیوس) در معرض اکسیژن اکسید می‌شوند. توسعه‌های انجام شده در زمینه فناوری ذخیره انرژی، لزوم بررسی رفتار ایروژل‌های کربنی در دماهای زیاد را به‌عنوان انتخابی برای این سامانه‌ها آشکار می‌کند. هدف این مقاله، تحلیل سینتیکی اکسایش ایروژل کربنی با روش سینتیکی غیر...
This work investigates the potentialities of thermal analysis (TA) coupled with mass spectrometry (MS) technique by studying decomposition calcium oxalate monohydrate (CaC2O4·H2O). The aim this is twofold: to demonstrate, at first, efficacy coupling gravimetric (TG)-MS experimental approach check presence intermediate reactions beyond conventional three-step decomposition: dehydration, decarbon...
Functional features of Ni-W composite materials combined with successful performance enabled a breakthrough in their broad application. To disclose the formation pathway at extreme conditions combustion synthesis NiO-WO3-Mg-C and NiWO4-Mg-C systems for optimization procedure, process was modeled under programmed linear heating by thermal analysis methods. The reduction kinetics tungsten nickel ...
