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).
Damage to these hair cells results in decreased hearing sensitivity, i.e. sensorineural hearing loss, and because human hair cells are incapable of regeneration, this damage is permanent. However, other organisms, such as the frequently studied zebrafish, have regenerating hair cells.air 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.
