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: Nerve growth factors reduction and blood-brain barrier distribution is one of the characteristics of multiple sclerosis (MS). Active life-style is known as a complementary and important strategy in MS therapy. The aim of the current study was to investigate the relationship between aerobic capacity and physical activity with serum level of nerve growth factors and markers of blood-b...
barrier properties are one of the most important factors in the edible film. in this study, edible mungbean films were prepared containing (0%, 15%, 30%, 45%) concentrations of rosemary aqueous extract. then the effect of rosemary was investigated on colorimetric and barrier properties (water vapor permeability, oxygen permeability). rosemary extract increased the absorption of color in the vis...
