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.
Open Fit Hearing Aids. Open fit hearing aids do not completely fill your ear canal. Instead, an open fit device is usually a very small behind-the-ear hearing aid with a small tube or wire that connects to a speaker in the ear canal.ustom Fit Hearing Aids. Custom fit hearing aids are just that custom molded to fit inside your ear canal. They can be completely inside the ear canal, fit partly inside, fill the lower portion of the outer ear, or fill most of the bowl-shaped area of the outer ear.
