Conventionally, smooth UHMWPE surfaces are used for total joint replacements; however, smooth surface contacts have been shown to be inadequate in friction reduction and/or anti-wear.
The inadequate funding flows created friction between communities and health staff and between facility managers and higher levels of the health system.
In part this was due to an incomplete understanding of the sometimes non-obvious force of friction, and a consequently inadequate view of the nature of natural motion.
Friction in control valves and inadequate controller tuning are two of the major sources of control loop performance degradation.
These values were gap filled for conditions at night when friction velocity was low (i.e. inadequate turbulent mixing) and corrected for energy-balance closure.
A major contributor to the inadequate teamwork of ORs is a culture characterized by interprofessional friction, a "silo mentality," and "tribalism" among the professions [ 2].
The results show that commonly used correlations for interfacial friction factor, which are generally developed in rectangular ducts, are inadequate, especially under conditions of increased liquid viscosity.
"That kind of crowding can cause a lot of problems," Rudovsky said, citing "friction between three men in a cell, increased inmate violence, correctional officer violence, inadequate access to medical care, social services, mental healthcare.
However, they have been specifically inadequate for biomedical implants due to their inferior tribological properties (low wear resistance, higher coefficient of friction, and lower hardness).
Inadequate boundary lubrication is associated with degenerative joint conditions such as osteoarthritis (OA), but relations between OA and surface friction, lubrication and wear in boundary lubrication are not well defined.
