Hydrogen gas has been widely recognized as an environmentally clean and renewable energy fuel, and it provides a way to reduce greenhouse gas and air pollution emission. A great deal of effort has been made to develop new techniques in the field of hydrogen energy, including hydrogen production, storage, and infrastructure. Recently a metallic gasket, which is made of type 316L stainless steel,...

Beam-to-column joints are one of the most common types in metal structures. In design load-bearing aluminium structures, welding, as a joining method, is often avoided because localised degradation mechanical properties heat-affected zone (HAZ). However, recent experimental studies on extent and strength HAZ show significant difference compared to very conservative rules when modern welding tec...

In this paper, a self-adaptive flange is proposed for the wind turbine shrouded by a flanged diffuser to reduce the wind loads acting on the flanged diffuser at high wind velocities. The self-adaptive flange can maintain the advantages of the flanged diffuser at wind velocities lower than the rated velocity and reduce the wind loads acting on the diffuser and blades at higher wind velocities. N...

simultaneous dislocation of both interphalangeal (ip) joints of same finger is a highly uncommon finding. and dislocation of metacarpophalangeal (mcp) joint along with interphalangeal joints of thumb are reported in literatures if, scarcely. here we are reporting the three cases, comprising of double dislocation of ip joints in little finger in two patients and simultaneous mcp and ip joint dis...
