Thanks largely to NASA-like advances in bowling-ball technology and the more liberal application of lubricants upon lane surfaces -- by bowling center proprietors seeking to enliven a game of fickle popularity -- the number of perfect games has exploded.
The use of lubricants, namely, substances introduced into the interface between sliding surfaces to diminish friction, is an ancient practice, and Egyptian pictures dating back 4,000 years show the application of lubricants to reduce the friction involved in dragging heavy monuments.
Many studies dealing with the application of lubricants have been published [ 18, 24– 26]—the outcome being controversial.
Proper applications of lubricants increase the lifetime and efficiency of machinery and decrease long-term costs in terms of energy consumption, maintenance requirements and reduce operating temperatures [1, 2, 3].
With an appropriate application of solid lubricant additives in the sliding interface, the friction reduction and wear resistance properties of the lubricant have been successfully improved.
Carrying eight adults and achieving happiness will require sedatives and a predeparture application of silicone lubricant.
Rhythmical Massage/Embrocation: Rhythmic massage/embrocation invented by Ita Wegman in the 1920th is based on a standardized series of manual movements and directional strokes and involves the application of a lubricant (oil, emulsion or ointment) to a specific area of the body by sliding motions of the hands with the intensity of touch alternating rhythmically between the two hands.
This study reviews the application of general lubricants in drilling fluids and the potential of biolubricants derived from vegetable oils in exceeding the performance of hydrocarbon and mineral-based lubricants.
Taking a cue from this observation, an application of boundary lubricants such as DLC and ZDOL (dihydroxy derivative of perfluoropolyoxyalkane) on silicon micro-pillars (Figure 10) has proven to be effective in increasing the hydrophobicity and surface lubricity, resulting in lower μ values [29].
Aiming at the reduction of process forces, increased material removal rates and longer tool service life without application of cooling lubricants the Fraunhofer IPT has developed a novel process concept for laserassisted milling with local laser-induced material plastification before cutting.
