Specifically, the thermal deformation of the microtubules would cause a microflow inside the tubules to form a shearing stress to stimulate the odontoblast at the end of the channels. Despite limited computational simulation studies12,13, the complicated fluid–structure dynamics has only been ...
As used herein, the term “flexible film” refers to a material that has the ability to change into a large variety of determinate and indeterminate shapes without damage thereto in response to the action of an applied force, and return to its general original shape when the applied force is...

the orbiting wrap161may form a compression chamber (P). A boss portion162may be formed to protrude at a bottom surface of the orbiting scroll160, for example, a lateral surface opposite the orbiting wrap161. The boss portion162may engage the rotating shaft143to receive a rotary force ...
• The contact point of the reacting spring leg's force acts beyond the center of the plate area,causing the heel to pen first.This prevents rubbing of the seal surface prior to normal plate opening • As the velocity of flow decreases, torsion...
