Background: One of the main components in tissue engineering is scaffold, which may serve as a medium to support cell and growth. Scaffolds must have good compressive strength controlled biodegradability show biological activities while treating bone defects. This study uses Chitosan-gelatin (C–G) with flexibility elasticity high-strength carbonate hydroxyapatite (CHA), be ideal scaffold for en...
High purity polycrystalline niobium contained in boron-epoxy gasket was compressed in a diamond anvil cell (DAC). The pressure was increased in steps of 3 GPa and the diffraction patterns recorded at each pressure with the incident x-ray beam perpendicular to the load axis of the DAC (radial diffraction). The maximum pressure reached was 37.6 GPa. The compressive strength (differential stress) ...
the mechanical strength of cumin seed and the effects of moisture content, seed size, speed and direction of loading on the force and energy required to fracture cumin seed were investigated. the results showed that moisture and loading direction were significant at the 1% level on the force and energy required to fracture cumin seed. the effects of seed size on force and loading speed on energ...
مقدمه : روند افزایش جمعیت سالمند در دنیا به نحوی است که در سال 2050 بیش از 20% جمعیت جهان را سالمندان تشکیل خواهند داد که اکثریت آنها در کشورهای در حال توسعه ساکن خواهند بود . اختلالات روحی روانی از مهمترین مشکلات سالمندان می باشد . در گروههای قومی و اقلیتها موانعی مانند زبان و تحصیلات پایین وجود دارد که می تواند منجر به اشکال در تشخیص اختلالات روانشناخی شود. در این مطالعه مقطعی وضعیت دموگرافیک...
Introduction: Retention of fiber reinforced composite posts depends on the bond strength between post and cement, and cement and root dentin. The aim of this study is to evaluate the bond strength of one type of fiber post to radicular dentin with different adhesive cements. Materials and Methods: Crowns of 44 caries-free, human premolar were removed 2 mm below the CEJ and the roots were endod...
BACKGROUND We previously reported the arterial elasticity value we measured to reflect the characteristic features of vessel walls, and to possibly be useful for detecting early stage atherosclerosis in type 2 diabetes. Obesity, especially visceral adiposity, is well known to play a crucial role in the development of metabolic disorders and atherosclerosis. To assess whether arterial elasticity...
