doruntash ancient city )tchoghazanbil( was built about13 th century b.c and middle period of elam civilization. as a complex ,doruntash was protected by three concentrated walls which are named: inner wall, middle wall and outer wall .big ziggurat ,mausoleums and palaces are some of the must monuments of the ancient city .tchoghazanbil is also famous for its water technologies and water element...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
بندپایان در حدود 75درصد انواع جانوران از جمله کنه های ایکسودیده ، بزرگترین شاخه جانوری می باشند (یخچالی و حاجی حسن زاده زرزای, 1383). خانواده کنه های سخت در زیر راسته متااستیگماتا و راسته کنه سانان (آکارینا) از شاخه بندپایان قرار دارند (wall and shearer, 2001). تاکنون 650 گونه و در حدود 13 جنس در 5 زیرخانواده از آنها گزارش گردیده است (wall and shearer, 1997; wall and shearer, 2001 ). به طوری که...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Comparative study of microfossils from two kinds of sediments: chert intercalations (studied in thin section) and phosphorite/phosphatic carbonate (in thin section and maceration), from the upper Neoproterozoic Doushantuo phospho− rites in the Weng’an area, Guizhou Province, South China, shows that the phosphatized Megasphaera ornata and the chert−preserved Tianzhushania tuberifera should be re...
بندپایان با داشتن بیش از یک میلیون گونه، بزرگترین شاخه جانوری محسوب می شوند. خانواده کنه های سخت در زیر راسته متااستیگماتا و راسته کنه سانان (آکارینا) از شاخه بندپایان قرار دارند (wall and shearer, 2001). تاکنون 650 گونه و در حدود 13 جنس در 5 زیرخانواده از آنها گزارش گردیده است (wall and shearer, 2001 ). به طوری که 10 درصد کنه ها از حیوانات اهلی تغذیه می کنند و در انتقال عوامل بیماری زا به انسا...
introduction: the purpose of this study was to evaluate and compare canal preparation pattern of k3 and protaper rotary files in curved resin blocks. materials and methods: twenty-four resin blocks were used in this experimental study and randomly divided into two groups. their initial images were scanned. after preparation, their images were scanned again in the same position. pre and post pre...
Simple geometric models of the left ventricle and indirect experimental measurements suggest that the inner myocardial wall contributes the largest fraction to total wall thickening. We measured transmural differences in regional wall thickening directly, using an epicardial M mode echocardiographic transducer (6 mm diameter, 5 MHz) placed on the anterior free wall of the left ventricle. Wall t...
Among the different lateral force resisting systems, shear walls are of appropriate stiffness and hence are extensively employed in the design of high-rise structures. The architectural concerns regarding the safety of these structures have further widened the application of coupled shear walls. The present study investigated the optimal dimensional design of coupled shear walls based on the im...
