| age groups | Persons classified by age from birth (infant, newborn) to octagenarians and older (aged, 80 and over). (12 Dec 1998) |
|---|---|
| matched groups | A method of experimental control in which subjects in one group are matched on a one-to-one basis with subjects in other group's concerning all organism variables (e.g., age, sex, height, weight) which the experimenter believes could influence the variable being investigated. (05 Mar 2000) |
| minority groups | A subgroup having special characteristics within a larger group, often bound together by special ties which distinguish it from the larger group. (12 Dec 1998) |
| plant families and groups | Groupings that include specific plants within larger families or divisions. (12 Dec 1998) |
| self-help groups | Organizations which provide an environment encouraging social interactions through group activities or individual relationships especially for the purpose of rehabilitating or supporting patients, individuals with common health problems, or the elderly. They include therapeutic social clubs. (12 Dec 1998) |
| sensitivity training groups | A group of people who meet in an unstructured setting to learn about themselves, interpersonal relationships, and group processes and about larger social systems. (12 Dec 1998) |
| diagnosis-related groups | A system for classifying patient care by relating common characteristics such as diagnosis, treatment, and age to an expected consumption of hospital resources and length of stay. Its purpose is to provide a framework for specifying case mix and to reduce hospital costs and reimbursements and it forms the cornerstone of the prospective payment system. (12 Dec 1998) |
| occupational groups | Members of the various professions (e.g., physicians) or occupations (e.g., police). (12 Dec 1998) |

| virtual focus | The point from which divergent rays seem to proceed, or that at which they would meet if prolonged backward. (05 Mar 2000) |
| mink cell focus-inducing viruses | Murine leukaemia viruses discovered in 1976 by hartley, wolford, old, and rowe and so named because the viruses originally isolated had the capacity to transform cell foci in mink cell cultures. Mcf viruses are generated in a multi-step process by recombination with other viral types including akr, friend, moloney, and rauscher. (12 Dec 1998) |
| plasma focus | <radiobiology> The Plasma Focus is another device which depends on the pinch effect. Possible applications include both fusion and plasma propulsion, as well as other plasma research. In essence the plasma focus is generated by discharge of a current across the ends of two coaxial insulated conducting pipes. The Plasma Focus caused a huge stir when they generated copious neutrons, until it was discovered that the source of the neutrons was knockoffs from deuterium due to pinch accelerated electrons or ions. Plasma focus is sort of a point version of the Zpinch. (09 Oct 1997) |
