in this paper, the non-linear dynamic response of novel steel sandwich panel with hollow i-core subjected to blast loading was studied. special emphasis is placed on the evaluation of midpoint displacements and energy dissipation of the models. several parameters such as boundary conditions, strain rate, mesh dependency and asymmetrical loading are considered in this study. the material and geo...
abstract objectives: the purpose of this study was to investigate the relationship between core stability and lower extremity injuries in female athletes through functional tests. decreased core stability has been suggested to contribute to the etiology of lower extremity injuries. so far researches had been used non-functional tests to assess the core stability. material and methods: fifty col...
Abstract In this paper , the nonlinear the nonlinear free and forced axisymmetric vibration of a thin circular functionally graded plate with rigid core is formulated in terms of von-Karman’s dynamic equation , and a semi-analytical approach is developed.Functionally graded material (FGM) properties vary through the thickness of the plate.FGM s are spatial composites within which material prop...
a finite element study of teeth restored with post and core: effect of design, material, and ferrule
background: different postdesigns and materials are available; however, no consensus exists regarding superiority for stress distribution. the aim of this study was to evaluate the effect of design and material of post with or without ferrule on stress distribution using finite element analysis. materials and methods: a total of 12 three‑dimensional (3d) axisymmetric models of postretained cent...
وکتورهای آدنو ویروس همواره در طراحی واکسن برای کنترل ویروس hcv مورد استفاده قرار گرفته اند. با آنکه ژن core ویروس به دلیل شباهت بالا در بین ژنوتیپها در واکسنهای مختلف مورد استفاده قرار گرفته و از لحاظ تئوری از بهترین کاندیدهای واکسن به شمار می آید، دسته ای ازجدیدترین مطالعات به دلیل نقائص وارد بر ژن کامل از قسمتهای کوتاه شده ژن در ساخت واکسن استفاده می کنند. تاکنون مطالعه ای که به ارزیابی سیستم...
