Continuous silicon carbide fiber reinforced silicon carbide matrix(SiC_f/SiC) composites are attractive candidate materials for aerospace engine system and nuclear reactor system. In this paper, SiC_f/SiC composites w...
Some of the characteristics of post-modernism, such as opposition centers, denial of holism, identity, differences and uncertainties, have had a great impact on the view of education. Because the purpose of education ...
Because of the many potential medical applications of nanoparticles, considerable research has been conducted on the interactions between nanoparticles and biomembranes. We employed coarse- grained molecular dynamics ...
A HVAC (heating ventilating and air conditioning) system is generally designed to ventilate an indoor space. In windy and snowy climates dispersed snow particles in ambient air can enter the intake duct, potentially...
