With the increasing demand for underground resources in China, the construction of ultra-deep shafts is becoming more and more popular.In order to stabilize the shaft wall and reduce the collapse of the shaft wall during the shaft excavation, the freezing method is generally used in the construction.However, the vibration generated during blasting
Three dimensional (3D) bioprinting is a powerful tool, that was recently applied to tissue engineering.This technique allows the precise deposition of cells encapsulated in supportive bioinks to fabricate complex scaffolds, which are used to repair podocarpus gracilior column targeted tissues.Here, we review the recent developments in the applicati
Abstract Leiomyosarcoma of the inferior vena cava (IVCL) is a rare retroperitoneal tumor.We report two cases of level II (middle level, renal veins to hepatic veins) IVCL, who underwent en bloc resection with reconstruction of bilateral or left renal venous return using prosthetic grafts.In our cases, IVCL is documented domeless quartz nails to be
An experimental study was conducted to evaluate the rheological and molecular characterization of rubberized asphalt emulsion.One rubberized asphalt emulsion and an asphalt rubber (CRS-2TR and AC20-TR) and two conventional emulsions (CRS-2 and CRS-2P) were evaluated.The emulsions were characterized by conducting rheological and physical testing.The
