| BEAM | brain electrical activity monitoring |
|---|---|
| BEV | baboon endogenous virus; beam's eye view |
| EB | elective abortion; electron beam; elementary body; emotional behavior; endometrial biopsy; epidermol... |
| EBCT | electron-beam computed tomography |
| EB-IORT | intraoperative electron beam boost |
| neutral axis of straight beam | The axis perpendicular to the plane of loading of a beam at stresses within the proportional limit; it lies at the gravity axis of the cross-section of the beam. (05 Mar 2000) |

| neutral beam injection | <radiobiology> This is one of the fundamental plasma heating methods. A particle accelerator is used to create fast ion beams (the particle energies are on the order of 100 keV), the ion beam is then passed through a neutral gas region, where the ions neutralise via charge-exchange reactions with the neutral gas. The neutralised beam is then injected into a magnetically confined plasma. The neutral atoms are unaffected (not confined) by the magnetic field, but ionize as they penetrate into the plasma. The high-energy ions then transfer some of their energy to the plasma particles in repeated collisions, and heat the plasma. (09 Oct 1997) |
| electron beam | <microscopy> A stream of electrons in an electron optical system. (05 Aug 1998) |
| peritoneal dialysis, continuous ambulatory | Portable peritoneal dialysis using the continuous (24 hours a day, 7 days a week) presence of peritoneal dialysis solution in the peritoneal cavity except for periods of drainage and instillation of fresh solution. (12 Dec 1998) |
| mixed discrete-continuous random variable | <statistics> A random variable that may assume some values with probabilities and others with probability densities. For example, in a 35-year-old man with familial polyposis of the colon, the distribution of time until malignant disease occurs consists of a probability that he already has cancer (which would be assigned the waiting time 0), a probability density of developing it in the future and a probability that he will die of some other cause before he develops cancer.

| motion therapy, continuous passive | Movement of a body part initiated and maintained by a mechanical or electrical device to restore normal range of motion to joints, muscles, or tendons after surgery, prosthesis implantation, contracture flexion, or long immobilization. (12 Dec 1998) |
| continuous | Not interrupted, having no interruption. Origin: L. Continuus (18 Nov 1997) |
| continuous ambulatory peritoneal dialysis | Method of peritoneal dialysis performed in ambulatory patients with influx and efflux of dialysate during normal activities. (05 Mar 2000) |
| continuous bar retainer | A metal bar, usually resting on lingual surfaces of teeth, to aid in their stabilization and to act as indirect retainer's. Synonym: continuous clasp. (05 Mar 2000) |
| continuous capillary | A capillary in which small vesicles (caveolae) are numerous and pores are absent. (05 Mar 2000) |
| continuous clasp | A metal bar, usually resting on lingual surfaces of teeth, to aid in their stabilization and to act as indirect retainer's. Synonym: continuous clasp. (05 Mar 2000) |
| continuous culture | <cell culture> A culture of microorganisms in a liquid medium which is maintained under constant conditions with a constant nutrient supply so that it can grow steadily for an extended period of time. Compare: batch culture. (11 Jan 1998) |
| continuous epidural anaesthesia | Insertion of a catheter into the lumbar or caudal epidural space for the repeated injection of local anaesthetic solutions as a means of prolonging duration of anaesthesia. Synonym: fractional epidural anaesthesia. (05 Mar 2000) |
| continuous loop wiring | The formation of wire loops on both maxillary and mandibular teeth, for the placement of intermaxillary elastics; used in reduction and fixation of fractures. Synonym: Stout's wiring. (05 Mar 2000) |
| continuous murmur | A murmur that is heard without interruption throughout systole and into diastole. (05 Mar 2000) |
