Background Radiation
Background radiation is a measure of the level of ionizing radiation present in the environment at a particular location which is not due to deliberate introduction of radiation sources. Background radiation originates from a variety of sources, both natural and artificial. These include both cosmic radiation and environmental radioactivity from naturally occurring radioactive materials (such as radon and radium), as well as man-made medical X-rays, fallout from nuclear weapons testing and nuclear accidents. Definition Background radiation is defined by the International Atomic Energy Agency as "Dose or dose rate (or an observed measure related to the dose or dose rate) attributable to all sources other than the one(s) specified. So a distinction is made between dose which is already in a location, which is defined here as being "background", and the dose due to a deliberately introduced and specified source. This is important where radiation measurements are taken of a specifie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Background (1953 Film)
''Background'' (U.S. ''Edge of Divorce'') is a 1953 British domestic drama film dealing with the effects of divorce, directed by Daniel Birt and starring Valerie Hobson, Philip Friend and Norman Wooland. It was based on the 1950 play of the same title by Warren Chetham-Strode, who also wrote the screenplay for the film. It was made at Southall Studios, with sets designed by the art director Michael Stringer. A contemporary review in the ''Glasgow Herald'' gave the film a muted response, describing Hobson as "shrill" and Wooland as "too sympathetic", adding : " A heroic effort is made to apportion the blame fairly...yet intrinsically, one has to admit, the film has no great success." Plot John and Barbie Lomax (Friend and Hobson) have been married for almost 20 years, but the marriage has seemingly reached breaking point. After leaving the army, John has been working hard on making a career for himself as a barrister, which takes up all of his time and attention, leaving ...

Background (TV Series)
''Background'' was a Television in Canada, Canadian journalistic television series which aired on CBC Television from 1959 to 1962. Premise The series was an in-depth review of current news items. It replaced CBC's previous Sunday night journalistic series ''This Week''. It looked at the week's stories in more detail and was a forerunner to This Hour Has Seven Days. Its first season was hosted by University of Saskatchewan political science professor Rick Hart. Hart, however, was inexperienced in broadcasting and left the series after the first season. The series was led in following seasons by a selection of journalists and analysts who included Arnold Beichman, Alistair Cooke, Philip Deane, Robert Fulford (journalist), Robert Fulford, Robert McKenzie, Michael Maclear and Malcolm Muggeridge. Documentaries featured on ''Background'' included features on various world regions, the United Nations, and "The Rise and Fall of the Third Reich" by William L. Shirer. Douglas Leiterman ...

Background Independence
Background independence is a condition in theoretical physics that requires the defining equations of a theory to be independent of the actual shape of the spacetime and the value of various fields within the spacetime. In particular this means that it must be possible not to refer to a specific coordinate system—the theory must be coordinate-free. In addition, the different spacetime configurations (or backgrounds) should be obtained as different solutions of the underlying equations. Description Background independence is a loosely defined property of a theory of physics. Roughly speaking, it limits the number of mathematical structures used to describe space and time that are put in place "by hand". Instead, these structures are the result of dynamical equations, such as Einstein field equations, so that one can determine from first principles what form they should take. Since the form of the metric determines the result of calculations, a theory with background independence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Background Music
Background music (British English: piped music) is a mode of musical performance in which the music is not intended to be a primary focus of potential listeners, but its content, character, and volume level are deliberately chosen to affect behavioral and emotional responses in humans such as concentration, relaxation, distraction, and excitement. Listeners are uniquely subject to background music with no control over its Loudness, volume and content. The range of responses created are of great variety, and even opposite, depending on numerous factors such as, setting, culture, audience, and even time of day. Background music is commonly played where there is no audience at all, such as empty hallways and restrooms and fitting rooms. It is also used in artificial space, such as music played while on hold during a telephone call, and virtual space, as in the ambient sounds or thematic Video game music, music in video games. It is typically played at low volumes from multiple small ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Background Actor
A background actor or extra is a performer in a film, television show, stage, musical, opera, or ballet production who appears in a nonspeaking or nonsinging (silent) capacity, usually in the background (for example, in an audience or busy street scene). War films and epic films often employ background actors in large numbers: some films have featured hundreds or even thousands of paid background actors as cast members (hence the term "cast of thousands"). Likewise, grand opera can involve many background actors appearing in spectacular productions. On a film or TV set, background actors are usually referred to as "junior artists", "atmosphere", "background talent", "background performers", "background artists", "background cast members", or simply "background", while the term "extra" is rarely used. In a stage production, background actors are commonly referred to as " supernumeraries". In opera and ballet, they are called either "extras" or "supers". Casting Casting criteria ...

Background Artist
A background artist or sometimes called a background stylist or background painter is one who is involved in the process of animation who establishes the color, style, and mood of a scene drawn by an animation layout artist. The methods used can either be through traditional painting or by digital media such as Adobe Photoshop. Traditional methods involved painting entire production scenes for a television program or film. Current methods may involve painting primarily background keys or the establishing shot while production background artists paint the corresponding background paintings. Some fields in which a Background Artist may work: *Motion pictures *Television *Video games *The Internet Other artists who contribute to animated cartoons, but who are not Background Artists, are layout artists (who design the backgrounds, lighting, and camera angles), storyboard artists (who draw panels of the action from the script), character designers (who create the style and personality ...

Background Noise
Background noise or ambient noise is any sound other than the sound being monitored (primary sound). Background noise is a form of noise pollution or interference. Background noise is an important concept in setting noise levels. Background noises include environmental noises such as water waves, traffic noise, alarms, extraneous speech, bioacoustic noise from animals, and electrical noise from devices such as refrigerators, air conditioning, power supplies, and motors. The prevention or reduction of background noise is important in the field of active noise control. It is an important consideration with the use of ultrasound (e.g. for medical diagnosis or imaging), sonar, and sound reproduction. Other uses In astronomy, background noise or cosmic background radiation is electromagnetic radiation from the sky with no discernible source. In information architecture, irrelevant, duplicate or incorrect information may be called background noise. In physics and telecommunicat ...

Background Extinction Rate
Background extinction rate, also known as the normal extinction rate, refers to the standard rate of extinction in Earth's geological and biological history before humans became a primary contributor to extinctions. This is primarily the pre-human extinction rates during periods in between major extinction events. Overview Extinctions are a normal part of the evolutionary process, and the background extinction rate is a measurement of "how often" they naturally occur. Normal extinction rates are often used as a comparison to present day extinction rates, to illustrate the higher frequency of extinction today than in all periods of non-extinction events before it. Background extinction rates have not remained constant, although changes are measured over geological time, covering millions of years. Measurement Background extinction rates are typically measured in three different ways. The first is simply the number of species that normally go extinct over a given period of ti ...
