| staff cell | <pathology> Immature neutrophils released from the bone marrow reserve in response to acute demand. (18 Nov 1997) |
| staff development | The process by which the employer promotes staff performance and efficiency consistent with management goals and objectives. (12 Dec 1998) |
| staff of Aesculapius | A rod with only one serpent encircling it and without wings; symbol of medicine and emblem of the American Medical Association, Royal Army Medical Corps (Britain), and Royal Canadian Medical Corps. See: caduceus. Origin: L. Aesculapius, G. Asklepios, god of medicine (05 Mar 2000) |
| nursing staff | Personnel who provide nursing service to patients in an organised facility, institution, or agency. (12 Dec 1998) |
| nursing staff, hospital | Personnel who provide nursing service to patients in a hospital. (12 Dec 1998) |
| dental staff | Personnel who provide dental service to patients in an organised facility, institution or agency. (12 Dec 1998) |
| dental staff, hospital | Dental personnel practicing in hospitals. (12 Dec 1998) |
| auditory field | The space included within the limits of hearing of a definite sound, as of a tuning fork. (05 Mar 2000) |
| bright field illumination | <microscopy> The method of lighting the specimen with a solid cone of rays. Transmitted bright field illumination is performed by a substage condenser. Reflected bright field illumination is performed by a vertical illuminator. Compare: dark field illumination (05 Aug 1998) |
| bright field imaging | <microscopy> An imaging mode in a transmission electron microscopy that uses only unscattered Electrons to form the image. Contrast in such an image is due entirely to mass-thickness variations in amorphous samples, and may include diffraction contrast in crystalline samples. (05 Aug 1998) |
| bright field microscopy | <technique> Optical microscopy, in which absorption to a great extent and diffraction to a minor extent give rise to the image, as opposed to phase contrast or interference methods of microscopy. (18 Nov 1997) |
| Broca's field | The posterior part of the inferior frontal gyrus of the left or dominant hemisphere, corresponding approximately to Brodmann's area 44; Broca identified this region as an essential component of the motor mechanisms governing articulated speech. Synonym: Broca's area, Broca's field, motor speech centre. (05 Mar 2000) |
| cardioid dark field condenser | <microscopy> A condenser designed with two reflecting surfaces, the first, a spherical surface which reflects the rays to a second, cardioid (heart-shaped) surface. The virtue in such an arrangement is that, if the cardioid surface is of true figure, the lens is both achromatic and aplanatic. It has a limiting numerical aperture of about 1.0. Thus objectives of a greater numerical aperture cannot be used successfully with it. A true cardioid figure is the trace of a point on the circumference of a circle rolling around an equal, fixed circle. (05 Aug 1998) |
| magnetic field | The sphere of influence of a magnet. (05 Mar 2000) |
