| nursing methodology research | Research carried out by nurses concerning techniques and methods to implement projects and to document information, including methods of interviewing patients, collecting data, and forming inferences. The concept includes exploration of methodological issues such as human subjectivity and human experience. (12 Dec 1998) |
|---|---|
| nursing research | Research carried out by nurses, generally in clinical settings, in the areas of clinical practice, evaluation, nursing education, nursing administration, and methodology. (12 Dec 1998) |
| dental research | The study of laws, theories, and hypotheses through a systematic examination of pertinent facts and their interpretation in the field of dentistry. (12 Dec 1998) |
| operations research | A group of techniques developed to apply scientific methods and tools to solve the problems of decision making in complex organizations and systems. Operations research searches for optimal solutions in situations of conflicting goals and makes use of mathematical models from which solutions for actual problems may be derived. (12 Dec 1998) |
| epidemiologic research design | The form and structure of analytic studies in epidemiologic and clinical research. (12 Dec 1998) |
| united states office of research integrity | An office of the united states public health service organised in june 1992 to promote research integrity and investigate misconduct in research supported by the public health service. It consolidates the office of scientific integrity of the national institutes of health and the office of scientific integrity review in the office of the assistant secretary for health. The ori is in the office of the assistant secretary for health and its director reports directly to the assistant secretary for health, department of health and human services.

| achromatic lens | A compound lens made of two or more lens's having different indices of refraction, so correlated as to minimise chromatic aberration. (05 Mar 2000) |
| acoustic lens | In ultrasonography, a lens used to focus or diverge a sound beam; may be simulated by electronic manipulation of signals. (05 Mar 2000) |
| anterior pole of lens | The central point on the anterior surface of the lens of the eye. Synonym: polus anterior lentis. (05 Mar 2000) |
| anterior surface of lens | The anterior surface of the lens of the eye. Synonym: facies anterior lentis. (05 Mar 2000) |
| aplanatic lens | A lens designed to correct spherical aberration and coma (q.v.). Synonym: periscopic meniscus. (05 Mar 2000) |
| apochromatic lens | A compound lens designed to correct both spherical and chromatic aberrations. (05 Mar 2000) |
| asphenc lens | <physics> A lens made aplanatic by grinding the outer zones to a greater radius than the inner zones. Aplanatic condensers can be made in this way. A simple aspheric lens is widely used as a lamp condenser because of its efficiency in converging light rays to one focal plane. (05 Aug 1998) |
| aspheric lens | A lens with a paraboloidal surface that eliminates spherical aberration. (05 Mar 2000) |
| astigmatic lens | A lens in which one of the surfaces is curved in one meridian and less curved in the opposite meridian; e.g., a teaspoon or a football. Synonym: astigmatic lens. (05 Mar 2000) |
