Transition (genetics)
Transition, in genetics and molecular biology, refers to a point mutation that changes a purine nucleotide to another purine ( A ↔ G), or a pyrimidine nucleotide to another pyrimidine ( C ↔ T). Approximately two out of three single nucleotide polymorphisms (SNPs) are transitions. Transitions can be caused by oxidative deamination and tautomerization. Although there are twice as many possible transversions, transitions appear more often in genomes, possibly due to the molecular mechanisms that generate them. 5-Methylcytosine is more prone to transition than unmethylated cytosine, due to spontaneous deamination. This mechanism is important because it dictates the rarity of CpG islands. See also * Transversion Transversion, in molecular biology, refers to a point mutation in DNA in which a single (two ring) purine ( A or G) is changed for a (one ring) pyrimidine ( T or C), or vice versa. A transversion can be spontaneous, or it can be caused by i ... References ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Transition State
In chemistry, the transition state of a chemical reaction is a particular configuration along the reaction coordinate. It is defined as the state corresponding to the highest potential energy along this reaction coordinate. It is often marked with the double dagger ‡ symbol. As an example, the transition state shown below occurs during the SN2 reaction of bromoethane with a hydroxide anion: The activated complex of a reaction can refer to either the transition state or to other states along the reaction coordinate between reactants and products, especially those close to the transition state.Peter Atkins and Julio de Paula, ''Physical Chemistry'' (8th ed., W.H. Freeman 2006), p.809 According to the transition state theory, once the reactants have passed through the transition state configuration, they always continue to form products. History of concept The concept of a transition state has been important in many theories of the rates at which chemical reactions occ ...

Transition (literary Journal)
''transition'' was an experimental literary journal that featured surrealist, expressionist, and Dada art and artists. It was founded in 1927 by Maria McDonald and her husband Eugene Jolas and published in Paris. They were later assisted by editors Elliot Paul (April 1927 – March 1928), Robert Sage (October 1927 – Fall 1928), and James Johnson Sweeney (June 1936 – May 1938). Origins The literary journal was intended as an outlet for experimental writing and featured modernist, surrealist and other linguistically innovative writing and also contributions by visual artists, critics, and political activists. It ran until spring 1938. A total of 27 issues were produced. It was distributed primarily through Shakespeare and Company, the Paris bookstore run by Sylvia Beach. While it originally almost exclusively featured poetic experimentalists, it later accepted contributions from sculptors, civil rights activists, carvers, critics, and cartoonists. Editors who joined the jour ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Transition (linguistics)
A transition or linking word is a word or phrase that shows the relationship between paragraphs or sections of a text or speech. Transitions provide greater cohesion by making it more explicit or signaling how ideas relate to one another. Transitions are, in fact, "bridges" that "carry a reader from section to section". Transitions guide a reader/listener through steps of logic, increments of time, or through physical space. Transitions "connect words and ideas so that ..readers don't have to do the mental work for hemselves" Definition In simple terms, a transition word demonstrates the relationship between two portions of a text or spoken language. By using the imagery of a bridge, a person can see how these words take readers/listeners from one statement to another. By using these words, people can better build a sentence and convey what they are trying to say in a more concise manner. Coordinating transitions Elements in a coordinate relationship are equal in rank, quality ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Transition (fiction)
Transitions in fiction are words, phrases, sentences, paragraphs, or punctuation that may be used to signal various changes in a story, including changes in time, location, point-of-view character, mood, tone, emotion, and pace. Transitions are sometimes listed as one of various fiction-writing modes. Purpose Transitions provide for a seamless narrative flow as a story shifts in time, location, or point-of view. They aid the internal logic of a story by moving readers from sentence to sentence, paragraph to paragraph, idea to idea, scene to scene, and chapter to chapter with grace and ease. Transitions in fiction also refer to how the trajectory of characters changes according to the various factors that affect them. The spatial and temporal changes affecting the characters help in the plot development. This shift can also denote a parallel transition that takes place regarding the state of mind of the character. Types Transitions in fiction may take any of several forms, inc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Social Change
Social change is the alteration of the social order of a society which may include changes in social institutions, social behaviours or social relations. Definition Social change may not refer to the notion of social progress or sociocultural evolution, the philosophical idea that society moves forward by evolutionary means. It may refer to a paradigmatic change in the socio-economic structure, for instance the transition from feudalism to capitalism, or hypothetical future transition to some form of post-capitalism. Social development refers to how people develop social and emotional skills across the lifespan, with particular attention to childhood and adolescence. Healthy social development allows us to form positive relationships with family, friends, teachers, and other people in our lives. Accordingly, it may also refer to social revolution, such as the Socialist revolution presented in Marxism, or to other social movements, such as women's suffrage or the civil ri ...

Transition Management (governance)
Transition management is a governance approach that aims to facilitate and accelerate sustainability transitions through a participatory process of visioning, learning and experimenting. In its application, transition management seeks to bring together multiple viewpoints and multiple approaches in a 'transition arena'. Participants are invited to structure their shared problems with the current system and develop shared visions and goals which are then tested for practicality through the use of experimentation, learning and reflexivity. The model is often discussed in reference to sustainable development and the possible use of the model as a method for change. Key principles to transition management as a form of governance: * seeks to widen participation by taking a multi-actor approach in order to encompass societal values and beliefs * takes a long-term perspective (between 1-3 generations) creating a basket of visions in which short-term objectives can be identified * focuse ...

Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quic ...

Photochromic Lens
A photochromic lens is an optical lens that darkens on exposure to light of sufficiently high frequency, most commonly ultraviolet (UV) radiation. In the absence of activating light, the lenses return to their clear state. Photochromic lenses may be made of polycarbonate, or another plastic. Glass lenses use visible light to darken. They are principally used in glasses that are dark in bright sunlight, but clear, or more rarely, lightly tinted in low ambient light conditions. They darken significantly within about a minute of exposure to bright light and take somewhat longer to clear. A range of clear and dark transmittances is available. In one sort of technology, molecules of silver chloride or another silver halide are embedded in photochromic lenses. They are transparent to visible light without significant ultraviolet component, which is normal for artificial lighting. In another sort of technology, organic photochromic molecules, when exposed to ultraviolet (UV) rays as in ...

Transition (computer Science)
Transition refers to a computer science paradigm in the context of communication systems which describes the change of communication mechanisms, i.e., functions of a communication system, in particular, service and Communications protocol, protocol components. In a transition, communication mechanisms within a system are replaced by functionally comparable mechanisms with the aim to ensure the highest possible quality, e.g., as captured by the quality of service. Transitions enable communication systems to adapt to changing conditions during runtime. This change in conditions can, for example, be a rapid increase in the load on a certain service that may be caused, e.g., by large gatherings of people with mobile devices. A transition often impacts multiple mechanisms at different communication layers of a OSI model, layered architecture. Mechanisms are given as conceptual elements of a networked communication system and are linked to specific functional units, for example, as a se ...
