thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
Background. This paper presents the study concerning hot-spot selection in the assessment of whole slide images of tissue sections collected from meningioma patients. The samples were immunohistochemically stained to determine the Ki-67/MIB-1 proliferation index used for prognosis and treatment planning. Objective. The observer performance was examined by comparing results of the proposed metho...
OBJECTIVES The purpose of this study was to evaluate the effect of hot pressing on the shear bond strength of a Au-Pt-Pd alloy-porcelain composite. METHODS Several metal-porcelain composites specimens were produced by two different routes: conventional porcelain fused to metal (PFM) and hot pressing. In the latter case, porcelain was hot pressed onto a polished surface (PPPS) as well as a rou...
In this article, the fracture behavior of different AlSi coating micro-structures is investigated. By changing heating temperature, are obtained, due to varying diffusivity iron. To study micro-structures, uniaxial tensile tests conducted at 700 °C. The hot test involves as-coated press hardening steel in a furnace temperatures 750, 920 and 1000 °C for 6 minutes dwell time, after which sample c...
Background: Hot flash is a common problem in climactric (time course around menopause)and menopausal period. The most effective treatment of it is HRT but There is a serious need for alternative therapies for hot flashes, as hormone replacement therapy (HRT) is associated with increased rates of breast cancer and heart disease. Materials and Methods: This trial used a randomized, two-stage(...
