ANALYSIS OF INHERENT CHARACTERISTICS, LOAD SHARING CHARACTERISTICS, AND TRANSPORTATION MECHANICAL RESPONSE OF A TRANSMISSION SYSTEM IN A LUNAR SAMPLER AND ITS EXPERIMENTAL VERIFICATION

Analysis of Inherent Characteristics, Load Sharing Characteristics, and Transportation Mechanical Response of a Transmission System in a Lunar Sampler and Its Experimental Verification

A marvin pflaume instagram rotary driving component is the power output unit of a lunar sampler.A planetary gear system is used as the transmission system.The lunar sampler is subjected to an extremely rigorous mechanical environment during transportation.In this paper, the time-varying meshing stiffness curves of planetary gears are calculated by

Potential Use of 3D CORAGRAF-Loaded PDGF-BB in PLGA Microsphere Seeded Mesenchymal Stromal Cells in Enhancing the Repair of Calvaria Critical-Size Bone Defect in Rat Model

Our previous study evidenced that the 3D CORAGRAF loaded with PLGA microsphere constitutes PDGF-BB can support cell attachment and proliferation and can induce an osteogenic commitment of mesenchymal stromal cells in the in vitro condition.However, how this construct can perform in pathophysiological conditions in terms of repairing critical bone d
