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.
cathode-ray oscilloscope, CRO, oscilloscope cardiac monitor, heart monitor - a piece of electronic equipment for continual observation of the function of the heart cathode-ray tube, CRT - a vacuum tube in which a hot cathode emits a beam of electrons that pass through a high voltage anode and are focused or deflected before hitting a phosphorescent screen
