| Fourier transform | Analysis based on the mathematical function first formulated by jean-baptiste-joseph fourier in 1807. The function, known as the fourier transform, describes the sinusoidal pattern of any fluctuating pattern in the physical world in terms of its amplitude and its phase. It has broad applications in biomedicine, e.g., analysis of the X-ray crystallography data pivotal in identifying the double helical nature of DNA and in analysis of other molecules, including viruses, and the modified back-projection algorithm universally used in computerised tomography imaging, etc. (12 Dec 1998) |
| immunoelectrophoresis, two-dimensional | Immunoelectrophoresis in which a second electrophoretic transport is performed on the initially separated antigen fragments into an antibody-containing medium in a direction perpendicular to the first electrophoresis. (12 Dec 1998) |
| electrophoresis, gel, two-dimensional | Electrophoresis in which a second perpendicular electrophoretic transport is performed on the separate components resulting from the first electrophoresis. This technique is usually performed on polyacrylamide gels. (12 Dec 1998) |
| two-dimensional chromatography | Paper chromatography in which a spot, located originally in one corner of a sheet, is developed in one direction along one side of the sheet, after which the sheet is rotated 90 |
| two dimensional gel electrophoresis | <technique> A high resolution separation technique in which protein samples are separated by isoelectric focussing in one dimension and then laid on an SDS gel for size determined separation in the second dimension. Can resolve hundreds of components on a single gel. (18 Nov 1997) |
| rotational transform | <radiobiology> \iota = 2PI/q) Due to the combination of applied toroidal field and induced poloidal field, the magnetic field lines wind helically around the torus (and on most flux surfaces they fill the surface ergodically). The rotational transform is a measure of this helicity, and is defined as the average angle the field line shifts in the poloidal direction per complete circuit in the toroidal direction. The quantity q = 2\pi / \iota is known as the "safety factor'' because of its role in stability theory. A magnetic field configuration is said to posses rotational transform if the lines of force, after one complete circuit around the configuration (for example, a torus) do not simply close exactly on themselves, but are instead rotated through some angle about the magnetic axies.

| transform | To be changed in form; to be metamorphosed. "His hair transforms to down." (Addison) 1. To change the form of; to change in shape or appearance; to metamorphose; as, a caterpillar is ultimately transformed into a butterfly. "Love may transform me to an oyster." (Shak) 2. To change into another substance; to transmute; as, the alchemists sought to transform lead into gold. 3. To change in nature, disposition, heart, character, or the like; to convert. "Be ye transformed by the renewing of your mind." (Rom. Xii. 2) 4. <mathematics> To change, as an algebraic expression or geometrical figure, into another from without altering its value. Origin: L. Transformare, transformatum; trans across, over + formare to from: cf. F. Transformer. See Form. Source: Websters Dictionary (01 Mar 1998) |

| Fourier transfer | A mathematical technique to express a time-varying function or signal into components at different frequencies, giving the phase and amplitude of each; used in computed tomography and magnetic resonance image reconstruction transformation. (05 Mar 2000) |
| dimensional stability | The property of a material to retain its size and form. (05 Mar 2000) |
| three-dimensional diffraction pattern | <optics> The diffraction pattern (of a point source) that appears in the three-dimensional space in and near the focal plane. For an aberration-free, diffraction- limited system, the slice of the diffraction pattern in the focal plane is the Airy disk and its surrounding diffraction rings. Above and below focus, the pattern changes periodically along the axis of the light beam so that bright and dark Airy-disk-like patterns appear alternately. The axial period of repeat is spaced twice as far apart as the radial period of repeat in the Airy disk and its diffraction rings (05 Aug 1998) |
