Anatomical Terms Of Location
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

Geometric Term Of Location
Geometric terms of location describe directions or positions relative to the shape of an object. These terms are used in descriptions of engineering, physics, and other sciences, as well as ordinary day-to-day discourse. Though these terms themselves may be somewhat Ambiguity, ambiguous, they are usually used in a context in which their meaning is clear. For example, when referring to a drive shaft it is clear what is meant by axis of rotation, axial or Radial direction, radial directions. Or, in a free body diagram, one may similarly infer a sense of orientation by the forces or Otherkin, other Vector space, vectors represented.{{Citation needed, date=March 2024 Examples Common geometric terms of location are: * Axial – along the center of a round body, or the axis of rotation of a body * Radius, Radial – along a direction pointing along a radius from the center of an object, or perpendicular to a curved path. * Circumference, Circumferential (or Azimuth, azimuthal) – fol ...

Axis Of Rotation
Rotation or rotational/rotary motion is the circular movement of an object around a central line, known as an ''axis of rotation''. A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a ''center of rotation''. A solid figure has an infinite number of possible axes and angles of rotation, including chaotic rotation (between arbitrary orientation (geometry), orientations), in contrast to rotation around a fixed axis, rotation around a axis. The special case of a rotation with an internal axis passing through the body's own center of mass is known as a spin (or ''autorotation''). In that case, the surface intersection of the internal ''spin axis'' can be called a ''pole''; for example, Earth's rotation defines the geographical poles. A rotation around an axis completely external to the moving body is called a revolution (or ''orbit''), e.g. Earth's orbit around the Sun. The en ...

Axial Bond
Cyclohexane conformations are any of several three-dimensional shapes adopted by cyclohexane. Because many compounds feature structurally similar six-membered rings, the structure and dynamics of cyclohexane are important prototypes of a wide range of compounds. The internal angles of a regular, flat hexagon are 120°, while the preferred angle between successive bonds in a carbon chain is about 109.5°, the tetrahedral angle (the arc cosine of −). Therefore, the cyclohexane ring tends to assume non-planar (warped) conformations, which have all angles closer to 109.5° and therefore a lower strain energy than the flat hexagonal shape. Consider the carbon atoms numbered from 1 to 6 around the ring. If we hold carbon atoms 1, 2, and 3 stationary, with the correct bond lengths and the tetrahedral angle between the two bonds, and then continue by adding carbon atoms 4, 5, and 6 with the correct bond length and the tetrahedral angle, we can vary the three dihedral angles ...

Modal Frame
A modal frame in music is "a number of types permeating and unifying Music of Africa, African, Music of Europe, European, and Music of the United States, American song" and melody., quoted in Richard Middleton (1990/2002). ''Studying Popular Music'', p. 203. Philadelphia: Open University Press. . It may also be called a melodic mode. "Mode" and "frame" are used interchangeably in this context without reference to scalar or rhythmic modes. Melodic modes define and generate melodies that are not determined by harmony, but purely by melody. A note frame, is a melodic mode that is Atonality, atonic (without a tonic (music), tonic), or has an unstable tonic. Modal frames may be defined by their: *floor note: the bottom of the frame, felt to be the lowest note, though isolated notes may go lower, *ceiling note: the top of the frame, *central note: the center around which other notes cluster or gravitate, *upper or lower focus: portion of the mode on which the melody temporarily dwells, ...

Fan (machine)
A fan is a powered machine that creates airflow. A fan consists of rotating vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an ''impeller'', ''Rotor (electric), rotor'', or ''runner''. Usually, it is contained within some form of housing, or case. This may direct the airflow, or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used, including hydraulic motors, handcranks, and internal combustion engines. Mechanically, a fan can be any revolving wikt:vane#English, vane, or vanes used for producing air current, currents of air. Fans produce air flows with high volume and low pressure (although higher than ambient pressure), as opposed to gas compressor, compressors which produce high pressures at a comparatively low volume. A fan blade will often rotate when exposed to an air-fluid stream, and devices ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axial Age
''Axial Age'' (also ''Axis Age'', from the German ) is a term coined by the German philosopher Karl Jaspers. It refers to broad changes in religious and philosophical thought that occurred in a variety of locations from about the 8th to the 3rd century BCE. According to Jaspers, during this period, universalizing modes of thought appeared in Persia, India, China, the Levant, and the Greco-Roman world, in a striking parallel development, without any obvious admixture between these disparate cultures. Jaspers identified key thinkers from this age who had a profound influence on future philosophies and religions, and identified characteristics common to each area from which those thinkers emerged. The historical validity of the Axial Age is disputed. Some criticisms of Jaspers include the lack of a demonstrable common denominator between the intellectual developments that are supposed to have emerged in unison across ancient Greece, the Levant, India, and China; lack of any radica ...

Axial Seamount
Axial Seamount (also Coaxial Seamount or Axial Volcano) is a seamount, submarine volcano, and underwater shield volcano in the Pacific Ocean, located on the Juan de Fuca Ridge, approximately west of Cannon Beach, Oregon. Standing high, Axial Seamount is the youngest volcano and current eruptive center of the Cobb–Eickelberg Seamount chain. Located at the center of both a hotspot (geology), geological hotspot and a mid-ocean ridge, the seamount is geologically complex, and its origins are still poorly understood. Axial Seamount is set on a long, low-lying plateau, with two large rift zones trending to the northeast and southwest of its center. The volcano features an unusual rectangular caldera, and its flanks are pockmarked by fissures, hydrothermal vent, vents, Lava#Pāhoehoe, sheet flows, and pit craters up to deep; its geology is further complicated by its intersection with several smaller seamounts surrounding it. Axial Seamount was first detected in the 1970s by satell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axial, Colorado
Axial is an extinct coal mining town located in Moffat County, Colorado Colorado is a U.S. state, state in the Western United States. It is one of the Mountain states, sharing the Four Corners region with Arizona, New Mexico, and Utah. It is also bordered by Wyoming to the north, Nebraska to the northeast, Kansas ..., United States. History The Axial, Colorado, post office operated from March 6, 1883, until April 30, 1958. The community's central location near the "axis" of mining activity caused the name to be selected.
