| containment | The concept of regional or global eradication of communicable disease, proposed by Fred Lowe Soper (1893-1977) in 1949 for the eradication of smallpox. (05 Mar 2000) |

| containment of biohazards | Provision of physical and biological barriers to the dissemination of potentially hazardous biologically active agents (bacteria, viruses, recombinant DNA, etc.). Physical containment involves the use of special equipment, facilities, and procedures to prevent the escape of the agent. Biological containment includes use of immune personnel and the selection of agents and hosts that will minimise the risk should the agent escape the containment facility. (12 Dec 1998) |
| containment vessel | <radiobiology> Gas-tight shell or other enclosure around a fusion (or fission) reactor, to prevent accidental leakage of radioactive contents. (09 Oct 1997) |
| biological containment | <molecular biology> Refers to any number of methods to contain genetically engineered organisms by creating biochemical barriers to prevent them from growing outside the laboratory. In the case of bacteria and yeasts, genes in the organisms may be altered so that they need to have a supply of a nutrient that is normally found only in the laboratory. (21 Mar 1998) |
|---|---|
| physical containment | <cell culture> Creation of physical barriers to keep genetically engineered organisms inside the laboratory. (31 Dec 1997) |
| plasma containment | <physics> In physics experiments or nuclear fusion experiments, operation is intended to prevent, in an effective and sufficiently prolonged manner, the particles of a plasma from striking the walls of the container in which this plasma is produced. Plasma confinement is a fundamental requirement for obtaining net energy from a fusion plasma. The reason is that scattering (hence diffusion) is at least an order of magnitude more probable than fusion reactions. Hence, without confinement, the plasma fuel would disperse before enough fusion reactions could take place. (31 Dec 1997) |
