Growth in the experimental system used to characterize the 120-min lag phase of S. Typhimurium. (A) Overview of system for obtaining lag-phase cells. See Materials and Methods for details. (B) Growth curve showing lag phase in the experimental culture flask. Lag time was determined to be 2.09 h (n = 3).
CROS hearing aid. A Contralateral Routing Of Signals (CROS) hearing aid is a type of hearing aid that is used to treat unilateral hearing loss. It takes sound from the ear with poorer hearing and transmits to the ear with better hearing. Most systems are now wireless and are either behind the ear or custom built in-the-ear systems.
A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing.Cochlear implants may help provide hearing in patients who are deaf because of damage to sensory hair cells in their cochleas.These sensory cells unlike most of the other cells in the body, never regenerate. Thus, the hair cells are irreplaceable in any matter. There are 4 manufacturers for cochlear implants, and each one produces a different implant with a different number of electrodes. 2  The number of channels is not the sole basis upon which a manufacturer is chosen; the signal processing algorithm is another important consideration.
