Electromechanical braking system is the key way to improve the braking response ability of mine hoist.At present, the reliability research of electromechanical braking system is less.In order to further analyze and improve the reliability of electro-mechanical braking system, this paper adopts the reliability analysis method of electro-mechanical b
Lead-Bismuth Eutectic (LBE) is an interesting candidate as a coolant for Generation IV nuclear power plants.Lead-bismuth lubricated radial guide bearing is the key component of the mechanical pump in a lead-bismuth coolant system.In this paper, the transient calculation model of multiphase lubrication flow field of journal bearing is established by
Introduction: The time from dialysis onset to enrollment on the kidney waiting list (listing time) is a crucial step on the path to receiving a kidney allograft; however, this process has received very little research attention in the Eurotransplant (ET) area.Methods: We retrospectively analyzed data from the German transplantation registry, includ
OBJECTIVE: The aim of this study was to investigate the possibility that periarticular osteophytes plays a role as a appendicular joint stress marker (JSM) which reflects the biomechanical stresses on individuals and populations.METHODS: A total of 366 contemporary Japanese skeletons (231 males, 135 females) were examined closely to evaluate the pe
