The hydrogen embrittlement (HE) behavior of a commercial QP980 steel is studied in this work.The HE susceptibility results indicate that QP980 suffers from a severe HE, and the fracture mode transforms from ductile dimpling to brittle quasi-cleavage under the attack of hydrogen.The EBSD results show that strain-induced martensite transformation can
Abstract Background Varicose veins are one of the most common disease; however, secondary varicose veins caused by tricuspid valve regurgitation ceramics (TVR) are rare.Case presentation A patient who developed pulsating bleeding from superficial varicose veins due to TVR was successfully treated by endovenous laser ablation (EVLA) of the great sap
Abstract Background In hepatectomy, the preservation of portal perfusion and venous drainage in the remnant liver is important for securing postoperative hepatic function.Right hepatectomy is generally indicated when a hepatic tumor involves the right hepatic vein (RHV).However, if a sizable inferior RHV (IRHV) exists, hepatectomy with preservation
