Friction and wear in tribological systems are phenomena that can be interpreted on a macroscopic scale. The emergence of micro nano-sized requires the treatment through concept fractals. Thus, to perceive occurring macro-system, it is fundamental think about them at micro-scale nano-scale, center, for case, level hardness atomic composition. This article realizes survey main concepts treating i...

While the properties of joint fluid may affect the tribology of joint replacement prostheses, the flow parameters of joint fluid have not yet been examined in the context of total knee arthroplasty (TKA). The objective of this study was to evaluate the flow properties of joint fluids in patients undergoing index TKA or revision TKA. We hypothesized that an alteration of the properties of joint ...
