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).
Hearing Different Frequencies. Auditory hair cells are specialized along the length of the cochlea to respond to specific sound frequencies. Hair bundles are shown in blue.Benjamin Thiede & Jeffrey T. Corwin. Researchers gained insights into how cells in the auditory system become organized to hear different frequencies. The findings could lead to new approaches for certain kinds of hearing loss. The human ear can detect a wide range of frequencies, from the low rumbles of distant thunder to the high-pitched whine of a mosquito.
