tribonucleation?

what is tribonucleation??

 

[ScubaDadMiami]

In plainer English, when you crack your knuckles, you form a bubble due to the sudden removal of pressure in the joint. Just moving your body around creates these bubbles to some degree. This is tribonucleation, the creation of these bubble seeds through naturally occurring physiology.

Even when you have not been subjected to increase and then decrease of pressure, you still have micro bubble seeds traveling through your body. Some of this has to do with the turbulence of the blood as it moves through different regions of the body.

The formation of these seeds of gas is not fully understood. However, the fact is that they are there.

Subjecting yourself to increased pressure while diving and then ascending can allow dissolved gas to encounter these seeds, joining the seed and then growing on ascent. Enough of this leads to forms of decompression illness.

Thanks!....I had posted a question RE: the dangers of a few coctails, AFTER the dive....and someone had replied that generally not a problem, unless you get too exerted after the dive....

From Dr. Deco [ http://www.scubaboard.com/t41475.html ]

Many divers are probably exerting considerable stress and strain while boarding the boat resulting in considerable flexing maneuvers on the spine that are nucleating events. Flexation will most likely result in hydrodynamic cavitation by Stephan adhesion (sometimes this aspect is called by the name of “tribonucleation”). Flexing the spine while wearing weights is never performed during tables testing. A Human Use Committee would not approve it, since it would be considered too dangerous. :tut:

Also note that tribology is defined as: [ http://www.tribology-abc.com/abc/default.htm ]

Tribology is defined as the science and technology of interacting surfaces in relative motion, and embraces the study of friction, wear and lubrication.
