Gap

(gäp), city (1990 pop. 35,647), capital of Hautes-Alpes dept., SE France, on the Luye River at the foot of the Dauphiné Alps. A center for tourism, Gap is an agricultural market that manufactures clothing, wood products, and construction materials. Founded by Augustus c.14 B.C., it was the capital of medieval Gapençais, which was annexed to the crown of France in 1512. The city was devastated during the Wars of Religion (16th cent.).

GAP

(mathematics, tool)
Groups Algorithms and Programming.

A system for symbolic mathematics for computational discrete algebra, especially group theory, by Johannes Meier, Alice Niemeyer, Werner Nickel, and Martin Schonert of Aachen. GAP was designed in 1986 and implemented 1987. Version 2.4 was released in 1988 and version 3.1 in 1992.

gap

(1) The space between blocks of data on magnetic tape.

(2) The space in a read/write head over which magnetic flux (energy) flows causing the underlying magnetic tape or disk surface to become magnetized in the corresponding direction.

6) In such cases, the urine osmolal gap, defined as urine osmolality - (2[Na+ + K+] + [urea] + [glucose]) should be used, since the gap mainly reflects the excretion of N[H.
After hemodialysis was performed, the patient's postdialysis serum showed an osmolal gap of 6 mOsm/kg and an EG concentration of 50 mg/dL (8.
The diagnosis of EG toxicity is made via a combination of the patient's history, the clinical picture, and a laboratory analysis showing an anion gap metabolic acidosis with an increased osmolal gap.
