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.
An otoscope (also known as an auriscope) is a medical instrument that allows healthcare professionals to better see the outer and middle portions of the ear. An otoscope is most commonly used to look inside the ear to look for ear wax buildup, signs of ear infection, and diagnose other issues. In young children and infants, an otoscope can diagnose issues that the child can not vocalize what is bothering them, as in the case of a baby with an ear infection.
