In order to improve the mechanical properties of the metal matrix composite, the copper-graphene composites were prepared by FSP (friction stir processing) method.The samples were analyzed through the metal microstructure observation test and mechanical test, the effects of agitation speed and the amount of graphite on the microstructure and tensil
Youth at risk for negative health outcomes due to reduced access to social, mental health, and educational support systems are in particular need of resources promoting social-emotional resilience and positive educational outcomes.A growing body of research documents the positive benefits of mindfulness-based interventions (MBIs), but few studies h
The paper describes the results of the parametric analysis obtained using the multibody systems.Numerical analysis allows checking different variants of the weapon without the need of building a lot of experimental models.As a part of the analysis, the impact of the slide mass, the recoil spring stiffness, the friction coefficients, the propellant
