Cavitation will increase the ranchy doodle leakage and discharge pressure fluctuation of axial piston pumps.In particular, specific cavitation damage may aggravate the pressure impact and performance degradation.The influence of the specific cavitation damage on the discharge pressure is unclear, and the need for fault detection of this damage is u
The spaceflight environment is relevant to conditions encountered by pathogens during the clairemax nude course of infection and induces novel changes in microbial pathogenesis not observed using conventional methods.It is unclear how microbial cells sense spaceflight-associated changes to their growth environment and orchestrate corresponding chan
