A surgeon injects the solution directly into the herniated disc on the spine to dissolve part of it and ease the pain. This process is under fluoroscopic control. Chymopapain is responsible for catalysis, both in vivo and in vitro, a rapid reduction in the viscosity and, as a consequence, the weight of the nucleus pulposus.
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
CD-R (Compact disc-recordable) is a digital optical disc storage format. A CD-R disc is a compact disc that can only be written once and read arbitrarily many times. CD-R discs (CD-Rs) are readable by most CD readers manufactured prior to the introduction of CD-R, unlike CD-RW discs.
A rupture disc (burst) Pressure-effect acting at a rupture disc A rupture disc, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.
An optical disc is a flat, usually [note 1] disc-shaped object that stores information in the form of physical variations on its surface that can be read with the aid of a beam of light. Optical discs can be reflective, where the light source and detector are on the same side of the disc, or transmissive, where light shines through the disc to ...
(The spelling disk and disc are used interchangeably except where trademarks preclude one usage, e.g., the Compact Disc logo. The choice of a particular form is frequently historical, as in IBM's usage of the disk form beginning in 1956 with the "IBM 350 disk storage unit".) Six hard disk drives Three floppy disk drives A CD-ROM (optical) disc ...
The EU parking disc regulation was skipped in France for a long time where a general time limit of 1 hour 30 was the only regulation in effect. The EU parking disc however allows a much wider range of parking regulations which were tested first in Bron at the beginning of January 2001 when a new tramway line reached the city center. The ...
