orphan date August 2009 An extensionagency is an organisation that practises Extension semantics extension , in the context of community development . An example is the Cooperative Extension Service , which aims to assist individuals or groups in defining and achieving their goals in rural communities in the USA. Extension agents are trained in the skills of extension, such as communication and group facilitation, and usually in technical areas of the sector they serve for example agriculture, health, or safety . Agricultural extension agencies promote more profitable and sustainable farming, while health extension agencies promote improved health. Extension agents are represented by professional organisations such as the http www.apen.org.au Australasia Pacific Extension Network and publish in journals such as the http www.joe.org Journal of Extension .

In mathematics , more specifically in ring theory , a ring extension or extension ring is a ring mathematics ring R with a subring S . We write R S and say R is a ring extension of S Given an extension R S of commutative rings and a prime ideal P of R , it follows that the intersection, say p , of P with S is a prime ideal of S . In this case we say that P lies over p . The situation is more complicated when R is not commutative. Examples A field extension is a special case of ring extension.

In abstract algebra , an abelian extension is a Galois extension whose Galois group is abelian group abelian . When the Galois group is a cyclic group , we have a cyclic extension . More generally, a Galois extension is called solvable if its Galois group is solvable group solvable . Any finite extension of a finite field is a cyclic extension. The development of class field theory has provided detailed information about abelian extensions of number field s, function field of an algebraic variety function fields of algebraic curve s over finite fields, and local field s. There are two slightly different concepts of cyclotomic extension s these can mean either extensions formed by adjoining roots of unity , or subextensions of such extensions. The cyclotomic field s are examples. Any cyclotomic extension for either definition is abelian. If a field K contains a primitive n th root of unity and the n th root of an element of K is adjoined, the resulting so called Kummer extension is an abelian extension if K has characteristic p we should say that p doesn t divide n , since otherwise this can fail even to be a separable extension . In general, however, the Galois groups of n th roots of elements operate both on the n th roots and on the roots of unity, giving a non abelian Galois group as semi direct product . The Kummer theory gives a complete description of the abelian extension case, and the Kronecker Weber theorem tells us that if K is the field of rational number s, an extension is abelian if and only if it is a subfield of a field obtained by adjoining a root of unity. There is an important analogy with the fundamental group in topology , which classifies all covering spaces of a space abelian covers are classified by its abelianisation which relates directly to the first ... min title cyclotomic extension Category Field extensions Category Algebraic number theory Category Class field theory de Abelsche Erweiterung es Extensi n abeliana fr Extension ab lienne nl Abelse uitbreiding ... more details
In mathematics , a Galois extension is an Algebraic extension algebraic field extension E F satisfying certain conditions described below one also says that the extension is Galois . The significance of being a Galois extension is that the extension has a Galois group and obeys the fundamental theorem of Galois theory . The definition is as follows. An algebraic field extension E F is Galois if it is normal extension normal and separable extension separable . Equivalently, the extension E F is Galois if and only if it is algebraic extension algebraic , and the fixed field field fixed by the automorphism group Aut E F is precisely the base field F . See the article Galois group for definitions of some of these terms and some examples. A result of Emil Artin allows one to construct Galois extensions as follows If E is a given field, and G is a finite group of automorphisms of E , then E F is a Galois extension, where F is the fixed field of G . Characterization of Galois extensions An important theorem of Emil Artin states that for a finite extension E F , each of the following statements is equivalent to the statement that E F is Galois E F is a normal extension and a separable extension . E is a splitting field of a separable polynomial with coefficients in F . E F Aut E F that is, the degree field theory degree of the field extension is equal to the order group theory order of the automorphism group of E F . Examples Adjoining to the rational number field the square root of 2 gives a Galois extension, while adjoining the cube root of 2 gives a non Galois extension. Both these extensions are separable, because they have characteristic zero . The first of them is the splitting field of X sup 2 sup &minus 2 the second has Normal extension normal closure that includes the complex ...

This extension is called the normal closure of the extension L of K . If L is a finite extension of K , then its normal closure is also a finite extension. References ...

Primer extension is a technique whereby the 5 end s of RNA or DNA can be mapped. Primer extension can be used to determine the start site of RNA transcription for a known gene. This technique requires a radiolabelled primer usually 20 50 nucleotides in length which is complementary to a region near the 3 end of the gene. The primer is allowed to anneal to the RNA and reverse transcriptase is used to synthesize cDNA from the RNA until it reaches the 5 end of the RNA. By running the product on a polyacrylamide gel , it is possible to determine the transcription start site transcriptional start site , as the length of the sequence on the gel represents the distance from the start site to the radiolabelled primer.

In metaphysics , extension is, roughly speaking, the property of taking up space . Ren Descartes defines extension as the property of existing in more than one dimension. For Descartes, the primary characteristic of matter is extension, just as the primary characteristic of mind is consciousness . This can be contrasted with current conceptions in quantum physics, where the Planck length , an almost unimaginably tiny quantity, represents reaching that distance scale where, it has been theorized, all measurement seemingly breaks down to that which can be subsumed at this scale, as distance only, or extension.
