Long service time and excessive vibration B 100 of aero-engine will cause failure of clamps, which usually fix pipelines on the outside of an aero-engine.In this paper, the nonlinear vibration characteristics caused by loosening clamps in aero-engine pipeline are determined.According to the real parameters of an aero-engine clamp-pipeline test rig,
Abstract: CD34 is routinely used to Telescopic Hood identify and isolate human hematopoietic stem/progenitor cells (HSPCs) for use clinically in bone marrow transplantation, but its function on these cells remains elusive.Glycoprotein ligands on HSPCs help guide their migration to specialized microvascular beds in the bone marrow that express vascu
At the beginning of the previous century, Newtonian mechanics was advanced by two new revolutionary theories, Quantum Mechanics (QM) and General Relativity (GR).Both theories have transformed our view of physical phenomena, with QM accurately predicting the results of experiments taking place at small length scales, and GR correctly describing obse
