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 callus, or callosity, is a section of skin that has become toughened and thick as a result of friction, pressure or irritation. If the friction (rubbing) is excessive, blisters will form rather than calluses. corn, clavus (plural: clavi) is a specially-shaped callus of dead skin. It usually forms on hairless and smooth (glabrous) skin surfaces, especially between the toes or fingers. Corns and calluses generally form when the skin tries to protect an underlying area from injury, pressure or rubbing.
