| flow injection analysis | The analysis of a chemical substance by inserting a sample into a carrier stream of reagent using a sample injection valve that propels the sample downstream where mixing occurs in a coiled tube, then passes into a flow-through detector and a recorder or other data handling device. (12 Dec 1998) |

| fluctuation analysis | Method used to determine (for example) how many ion channels contribute to the transmembrane current. On the assumption that each channel is either open or shut, the noise in the recorded current can be considered to arise from the statistical fluctuation in the number of channels open and the magnitude of the fluctuation gives an estimate of the conductance of a single channel. (18 Nov 1997) |
| fourier analysis | 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) |
| frequency analysis | <ecology, statistics> A method of evaluating vegetation in an area by establishing a transect and counting the occurrences of plant species at various sampling points along the transect. (07 Apr 1998) |
| least-squares analysis | A principle of estimation in which the estimates of a set of parameters in a statistical model are those quantities minimizing the sum of squared differences between the observed values of a dependent variable and the values predicted by the model. (12 Dec 1998) |
| linkage analysis | <genetics> Study aimed at establishing linkage between genes. Today linkage analysis serves as a way of gene-hunting and genetic testing. (12 Dec 1998) |

| academies and institutes | Organizations representing specialised fields which are accepted as authoritative; may be non-governmental, university or an independent research organization, e.g., national academy of sciences, brookings institution, etc. (12 Dec 1998) |

| algae and fungi | Algae represent a group of spore-propagating plants, unicellular or undifferentiated into root, stem, and leaf. They include seaweed and many unicellular fresh water plants, most of which contain chlorophyll. They account for about 90% of the earth's photosynthetic activity. Fungi are eukaryotic, heterotrophic organisms that live as saprobes or parasites and include mushrooms, yeasts, smuts, molds, etc. They lack chlorophyll. (12 Dec 1998) |
| alkyl and aryl transferases | <enzyme> A somewhat heterogeneous class of enzymes that catalyze the transfer of alkyl or related groups (excluding methyl groups). Registry number: EC 2.5 (12 Dec 1998) |
| allergy and immunology | A medical specialty concerned with the hypersensitivity of the individual to foreign substances and protection from the resultant infection or disorder. (12 Dec 1998) |
| alligators and crocodiles | Large, long-tailed reptiles, including caimans, of the order loricata. (12 Dec 1998) |
| Amine Precursor Uptake and Decarboxylation | <pharmacology, physiology> Paracrine cells of which argentaffin cells are an example. Usage of the term APUD is neither helpful nor memorable. Acronym: APUD (11 Nov 1997) |
