| africa, northern | The geographical area of africa comprising algeria, egypt, libya, morocco, and tunisia. It includes also the vast deserts and oases of the sahara. It is often referred to as north africa, french-speaking africa, or the magreb. (12 Dec 1998) |
| blot, northern | A technique in molecular biology, used mainly to separate and identify pieces of RNA. Called a Northern blot only because it is similar to a Southern blot (which is named after its inventor, the British biologist M.E. Southern). (12 Dec 1998) |
| blotting, northern | Detection of RNA that has been electrophoretically separated and immobilised by blotting on nitrocellulose or other type of paper or nylon membrane. (12 Dec 1998) |
| northern | 1. Of or pertaining to the north; being in the north, or nearer to that point than to the east or west. 2. In a direction toward the north; as, to steer a northern course; coming from the north; as, a northern wind. Northern diver. <zoology> See Loon. Northern lights. See Aurora borealis, under Aurora. <botany> Northern spy, an excellent American apple, of a yellowish colour, marked with red. Origin: AS. Northerne. Source: Websters Dictionary (01 Mar 1998) |
| Northern blot | <molecular biology, procedure> An electroblotting method in which RNA is transferred to a filter and detected by hybridisation to (32)P labelled RNA or DNA. (18 Nov 1997) |
| Northern blot analysis | A procedure similar to the Southern blot analysis, used mostly to separate and identify RNA fragments; typically via transferring RNA fragments from an agarose gel to a nitrocellulose filter followed by detection with a suitable probe. Origin: coined to distinguish it from eponymic Southern blot a. (05 Mar 2000) |
| northern territory | A territory in north central Australia, east of the state of queensland. Its capital is darwin. Originally a part of new south wales, it was annexed to south Australia in 1863, entered the commonwealth as part of it in 190l, transferred to the commonwealth in 1911, divided in 1927, but was reestablished in 1931. It was granted self government within the commonwealth of Australia in 1978. (12 Dec 1998) |
| Abbe's law of limiting resolution | <physics> For a periodic structure of units separated by distance d and obliquely illuminated by the unrefracted ray and one of the two diffracted rays (extremely oblique illumination). Abbe applied the law of diffraction: d = 0.5 lambda /NA, where: lambda = wavelength of the monochromic light or shortest of mixed wavelengths NA = the limiting numerical aperture (NA) of objective or condenser. (05 Aug 1998) |
| all or none law | Consistently total response to any effective stimulus. Synonym: all or none law. (05 Mar 2000) |
| American Law Institute formulation | Used in certain jurisdictions to determine criminal responsibility in legal proceedings. See: criminal insanity. (05 Mar 2000) |
| American Law Institute rule | A test of criminal responsibility (1962): "a person is not responsible for criminal conduct if at the time of such conduct as a result of mental disease or defect he lacks substantial capacity either to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of law." (05 Mar 2000) |
| Ampere's law | <physics> General equation in electromagnetism relating the magnetic field and the currents generating it. The various forms of the equation can be found in an introductory electromagnetism text. (09 Oct 1997) |
| Angstrom's law | A substance absorbs light of the same wavelength as it emits when luminous. (05 Mar 2000) |
| Arndt's law | An obsolete law stating that weak stimuli excite physiologic activity, moderately strong ones favour it, strong ones retard it, and very strong ones arrest it. (05 Mar 2000) |
