Using light instead of heat, the UV curing process is based on a photochemical reaction. Liquid monomers and oligomers are mixed with a small percent of photoinitiators, and then exposed to UV energy. In a few seconds, the products - inks, coatings or adhesives instantly harden.
(more on hair cells on the next page) Roughly in parallel with the row of 3,500 inner hair cells, three rows of outer hair cells (OHCâs) are situated along the same membrane. The main function of the inner hair cells is to pick up the membraneâs vibrations (like a microphone). The main function of the outer hair cells is to feed back mechanical energy to the membrane in order to amplify the resonance peaks, actively increasing the systemâs sensitivity by up to 60dB(*4C).
For hair cells on the external skin, see Hair follicle. For algal 'hair cells', see Trichocyte (disambiguation) . See also: Stereocilia (inner ear). Hair cells are the sensory receptors of both the auditory system and the vestibular system in all vertebrates.Through mechanotransduction, hair cells detect movement in their environment.esearch of the past decades has shown that outer hair cells do not send neural signals to the brain, but that they mechanically amplify low-level sound that enters the cochlea. The amplification may be powered by the movement of their hair bundles, or by an electrically driven motility of their cell bodies.
