| radiofrequency trapping | <radiobiology> Use of RF waves to pitch angle scatter particles flowing axially into a magnetic mirror cell. The particles are scattered out of the loss cone and are trapped. (See entries for pitch angle scattering, magnetic mirror, loss cone.) (09 Oct 1997) |

| radiofrequency | 1. Radiant energy of a certain frequency range; e.g., radio and television employ radiant energy having a frequency between 105-1011 Hz, while diagnostic X-rays have a frequency in the range of 3 × 1018 Hz. 2. In magnetic resonance imaging, the energy applied to switch or create a gradient in the magnetic field. (05 Mar 2000) |

| radio frequency or radiofrequency | <physics> Term used to describe electromagnetic radiation with frequencies less than infrared, but greater than audio frequencies, i.e., greater than about 15,000 Hz. Wavelengths are therefore less than about 20,000 km and greater than about 0.01 mm. (These numbers are not precise.) (09 Oct 1997) |
| radiofrequency plugging | <radiobiology> Use of axial ponderomotive force to plug an open-ended device. First demonstrated on RFC-XX, Institute of Plasma Physics, Nagoya University, Nagoya, Japan, and later demonstrated in the Phaedrus device at the University of Wisconsin. (09 Oct 1997) |
| radiofrequency pulse | In nuclear magnetic resonance, a short electromagnetic signal used to change the direction of the magnetic field. See: sequence pulse. (05 Mar 2000) |
| spin trapping | A technique for detecting short-lived reactive free radicals in biological systems by providing a nitrone or nitrose compound for an addition reaction to occur which produces an electron spin resonance spectroscopy-detectable aminoxyl radical. In spin trapping, the compound trapping the radical is called the spin trap and the addition product of the radical is identified as the spin adduct. (free rad res comm 1990;9(3-6):163) (12 Dec 1998) |
| entropy trapping | <radiobiology> The process of trapping an ordered beam of particles in a magnetic field configuration (for example, cusp geometry) by randomising the ordered motion of the particles, with corresponding increase in the entropy of the system. (09 Oct 1997) |
| exon trapping | <molecular biology, technique> A technique used to identify exons with a specialised vector. The vector has two exons that are normal, splicedtogether in a transcript.Fragments of DNA can be inserted into the intron, and when the insert is an exon, the exon is splicedinto the transcript, thereby giving a longer transcript that can be detected by Northern blotanalysis.
