Aqueous Lubrication : Natural and Biomimetic Approaches by Nicholas Spencer

By Nicholas Spencer

Guy lubricates normally with oil. Nature lubricates completely with water. natural water is a terrible lubricant, however the addition of proteins, particularly glycoproteins, can regulate surfaces to lead them to way more lubricating at gradual speeds. realizing how nature does this, and the actual constructions concerned, isn't just vital for the certainty of ailments corresponding to osteoarthritis, but additionally crucial for the profitable software of articulating implants, corresponding to hips and knees, in addition to the advance of clinical units akin to catheters and call lenses. a number of significant functions of water-based lubrication are already in position within the own care and nutrition industries, and extra business purposes of water-based lubrication may have an important optimistic effect at the atmosphere.

This publication is the 1st of its style. It brings jointly the newest learn in organic and biomimetic, water-based lubrication and is authored by way of the world's specialists within the box.

Theory of Parallel Mechanisms

This e-book includes mechanism research and synthesis. In mechanism research, a mobility method is first systematically provided. this system, in keeping with the author's screw idea, proposed in 1997, of which the generality and validity used to be in basic terms proved lately, is a truly advanced factor, researched through quite a few scientists during the last a hundred and fifty years.

Multifunctional materials for tribological applications

A major element of engineering surfaces is they must be multifunctional as designs of computer parts require more affordable, lighter, smarter, longer-wearing, and extra environmentally pleasant surfaces that see functions which are warmer, speedier, hugely pressurized, and uncovered to different more and more opposed environments.

Operator's guide to general purpose steam turbines: an overview of operating principles, construction, best practices, and troubleshooting

Whilst put in and operated competently, common objective steam generators are trustworthy and have a tendency to be forgotten, i. e. , out of sound and out of mind.  yet, they are often drowsing giants that could lead to significant complications if ignored.  3 actual steam turbine bad effects that instantly are evoked are: damage and secondary harm because of an overspeed failure.
