2017 Good Quality FEP Encapsulated O-Ring for Czech Republic Factories
2017 Good Quality FEP Encapsulated O-Ring for Czech Republic Factories Detail:
Encapsulated O Ring adopts special rubber resisting high temperature, F+ plastic and special engineering to compound this sealing product. It not only has low contraction permanent set functions of rubber O Ring, but also resistant heat, cold oil, friction, chemical corrusion and other performances. It can be used in all kind of dynamical seal and static seal widely, meanwhile can replace all traditional rubber and plastic O Ring.

When you spend your life in the water, I guess you tend to develop a good intuition for its subtleties. Dolphins have been observed to create bubble rings by exhaling air carefully in the middle of the vortices caused by the motion of their fins through the water, among other techniques.
Besides being nice to look at (and a neat demonstration of fluid mechanics), this phenomenon also might throw some light on dolphin cognition, since the skill to create the rings is a bit subtle and tends to be taught from one dolphin to the next via careful observation and practice. I’m also intrigued by the report that they seem to be using sonar to locate the vortex in the water, since that would be a fairly amazing bit of audio analysis.
