Nonlinear vibration of a fluid-filled single walled carbon nanotube (SWCNT) with simply supported ends is investigated in this paper based on Von-Karman’s geometric nonlinearity and the simplified Donnell’s shell theory. The effects of the small scales are considered by using the nonlocal theory and the Galerkin's procedure is used to discretize partial differential equations of the governing i...
during 2010-2011 a faunistic survey was carried out for collection and identification of edaphic mesostigmatic mites (acari: mesostigmata) in jiroft and suburb. mites were extracted from soil samples by berlese funnel. the mites were cleared in nesbit fluid and were mounted in hoyer medium on microscopic slides. in this study 43 spices from 26 genera and 16 families were collected and identifie...
The Lake Siah magnetite ± apatite deposit is situated in the northeastern of Bafq and Central Iran tectonic zone. The host rock of deposit is composed from lower Cambrian volcano-sedimentary sequence that has exposed as caldera complex. The iron mineralization is as massive ore and includes magnetite and hematite which form with apatite, quartz and calcite gangue minerals. Based on fluid inclus...
چکیده تمام نما مقدمه: این تحقیق برای بررسی میزان خلاقیت و عناصر آن (انعطاف- سیالی- ابتکار و بسط) در کارشناسان فوق برنامه های تربیت بدنی دانشگاههای تهران صورت گرفته است. بطور کلی خلاقیت به معنای توانایی تولید اندیشه ها و ایده های جدید و ترکیب آنها با یکدیگر و بیشتر در جنبه های فکری نظری و به اصطلاح فعالیتهای ذهنی و طراحی قبل از عمل به کار می رود و دارای چهار عنصر به شرح زیر می باشد. 1- سیالی...
هدف اصلی ما در این پایان نامه، مطالعه عملگردهای مثبت و نگاشت های حالت روی * – جبرهای باناخ و –c* جبرها می باشد. در وهله بعدی *- ایزومورفیسم های بین –c* جبرهای یکدار را مورد مطالعه قرای می دهیم . علاوه بر موارد فوق، پایداری –j* مشتقها روی –j* جبرها را به عنوان کاربردی از قضیه نقطه ثابت تعمیم یافته مورد مطالعه قرار می دهیم و نهایتا با پیدا کردن حل عمومی برای معادله تابعی ترکیبی چهارتایی جمعی، درج...
Introduction: The maternal perception of fetal movements at term has been used as an evaluative test of fetal wellbeing since the last 30 years, but there are different reports about its value. The aim of this study was evaluation of decreased fetal movement and relation to situation of fetus in uterus. It is significant that we understand the relationship between decreased fetal movement and i...
The heat transfer for a non-Newtonian power-law fluid over a moving surface is investigated by applying a uniform suction/injection velocity profile. The flow is influenced by internal heat generation/absorption. The energy equation is solved at constant surface temperature condition. The Merk-Chao series is applied to obtain a set of ODEs instead of a complicated PDE. The converted ordinary diffe...
The Zamin Hossein copper deposit, as a part of the Dehaj- Sarduiyeh metallogenic belt, is located about 170 km southeast of Kerman city. This deposit is accompanied by Eocene volcanic (andesite, andesi-basalt and pyroclastic) and Eocene intrusive body (granodiorite and granite). The propylitic, sericitic, argillic-sericitic and silicic alterations are associated with this deposit. Chalcopyrite ...
introduction a wide variety of world-class porphyry cu deposits occur in the urumieh-dohktar magmatic arc (udma) of iran.the arc is composed of calc-alkaline granitoid rocks, and the ore-hosting porphyry intrusions are dominantly granodiorite to quartz-monzonite (zarasvandi et al., 2015). it is believed that faults played an important role in the emplacement of intrusions and subsequentporphyry...
Namegh area is located northeast Kashmar, Khorasan Razavi Province, and contral parts of the Khaf-Kashmar-Bardaskan magmatic belt. Geology of the area consists of trachyandesite and pyroclastic rocks including trachyandesitic to rhyolitic tuff, which are intruded by monzodioritic dykes. Mineralization is occurred as vein type with NW-SE trending and 75°NE inclination hosted by trachyandesite an...
