Abstract: Although slightly affected by alterations in preload, the maximum first derivative of left ventricular pressure with respect to time, Max(dP/dt), is widely regarded as a simple and convenient ...

Abstract: Based on a new boundary lubrication model, the characteristics of lubricants under boundary lubrication at low sliding speed and low contact pressure such as in machine tool slideways are ...

Abstract: The clarification of the squeezing mechanism of lubricant, which flows between rough surfaces, is quite important for the improvement of the dynamic characteristics of sliding elements, and for ...
