در این پژوهش رفتار سایشی فولاد با پلاستیسیته حاصل از استحاله (TRIP) و فولاد دو فازی (DP) حاصل از دو چرخه عملیات حرارتی مختلف در یک فولاد کم آلیاژ استحکام بالا مورد بررسی قرار گرفت. آزمایش‌های سایش به‌صورت رفت و برگشتی تحت نیروی یک کیلوگرم و با سرعت خطی ثابت 1/0 متر بر ثانیه انجام شد و سپس سطح نمونه‌های سایش توسط میکروسکوپ الکترونی روبشی همراه با آنالیز نقطه‌ای بررسی گردید و به‌منظور ارزیابی نوع...
Commonly in designing hydroelectric dams and in the level of consulting engineers, for determining the hydroelectric potential of an storage, the analyze is done based on an RBS (Reliability Based Simulation) model with an obvious operation policy. In this paper the effect of optimizing release rules instead of using a fixed and know release policy, like what it is adopted in an RBS model, w...
drought preconditioning (dp) is a method of irrigation with low frequency and longer duration, to extend the root system and suppress drought damage in plants. in the present study, the effect of dp for 30 days on increasing tolerance to drought stress in two turfgrass species, creeping bentgrass (agrostis stolonifera cv.palustris) and tall fescue (festuca arundinacea cv. greystone) was investi...
the binding of drugs by plasma proteins is an important phenomenon, because it influences the size of the free fraction of the drugs in plasma. in this study the influence of dipyridamole (dp) on the protein binding of propranolol (pl) and pl on the protein binding of dp were studied alone and in the presence of nicotine (nc). the equilibrium dialysis was employed for protein binding stu...
Synthesizing the emerging directions of research at intersection differential privacy and cryptography.
Background: N-acetylcysteine (NAC) is a putative antioxidant and has gained attention as a promising agent for chelating heavy metals including lead. Considering the animal studies results, we hypothesized that adding NAC to the treatment regimen may improve the success of treatment with lead chelators. Methods: A total of 46 patients who were lead-poisoned opioid addicts were divided into two ...
successful clearance of hepatitis b virus (hbv) is a promising event in which host's immune system will attempt to get rid of the virus. the immunological events of hbsag seroclearance have attracted great attention in both natural history investigations and therapeutic trials. recent genome-wide association studies (gwas) has confirmed polymorphisms in the human leukocyte antigen (hla)-dp locu...
