Primary color

A set of primary colors consists of colorants or colored lights that can be mixed in varying amounts to produce a gamut of colors. This is the essential method used to create the perception of a broadread more... range of colors in, e.g., electronic displays, color printing, and paintings. Perceptions associated with a given combination of primary colors can be predicted by an appropriate mixing model that reflects the physics of how light interacts with physical media, and ultimately the retina.read less...

Primary Chronicle

The Tale of Bygone Years, often known in English as the Rus' Primary Chronicle, the Russian Primary Chronicle, or simply the Primary Chronicle, as well as also, after the author it has traditionally bread more...een ascribed to, Nestor's Chronicle, is an Old East Slavic chronicle (letopis) of Kievan Rus' from about 850 to 1110, originally compiled in Kiev around 1113. The work’s name originates from the opening sentence of the text, which reads: “These are the narratives of bygone years regarding the origin of the land of Rus’, the first princes of Kiev, and from what source the land of Rus’ had its beginning.” The work is considered to be a fundamental source in the interpretation of the history of the East Slavs. The Chronicle's content is known today from several surviving editions and codices that have been revised over the years and evince a slight degree of variation from each other.read less...

Primary biliary cholangitis

Primary biliary cholangitis (PBC), previously known as primary biliary cirrhosis, is an autoimmune disease of the liver. It results from a slow, progressive destruction of the small bile ducts of the read more...liver, causing bile and other toxins to build up in the liver, a condition called cholestasis. Further slow damage to the liver tissue can lead to scarring, fibrosis, and eventually cirrhosis.read less...

Primary production

In ecology, primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide. It principally occurs through the process of photosynthesis, which uses light as its soread more...urce of energy, but it also occurs through chemosynthesis, which uses the oxidation or reduction of inorganic chemical compounds as its source of energy. Almost all life on Earth relies directly or indirectly on primary production. The organisms responsible for primary production are known as primary producers or autotrophs, and form the base of the food chain. In terrestrial ecoregions, these are mainly plants, while in aquatic ecoregions algae predominate in this role. Ecologists distinguish primary production as either net or gross, the former accounting for losses to processes such as cellular respiration, the latter not.read less...

Primary source

In the study of history as an academic discipline, a primary source is an artifact, document, diary, manuscript, autobiography, recording, or any other source of information that was created at the tiread more...me under study. It serves as an original source of information about the topic. Similar definitions can be used in library science, and other areas of scholarship, although different fields have somewhat different definitions. In journalism, a primary source can be a person with direct knowledge of a situation, or a document written by such a person.read less...

Primary motor cortex

The primary motor cortex is a brain region that in humans is located in the dorsal portion of the frontal lobe. It is the primary region of the motor system and works in association with other motor aread more...reas including premotor cortex, the supplementary motor area, posterior parietal cortex, and several subcortical brain regions, to plan and execute movements. Primary motor cortex is defined anatomically as the region of cortex that contains large neurons known as Betz cells. Betz cells, along with other cortical neurons, send long axons down the spinal cord to synapse onto the interneuron circuitry of the spinal cord and also directly onto the alpha motor neurons in the spinal cord which connect to the muscles.read less...
