Quadrant (abdomen)
The human abdomen is divided into quadrants and regions by anatomists and physicians for the purposes of study, diagnosis, and treatment. The division into four quadrants allows the localisation of pain and tenderness, scars, lumps, and other items of interest, narrowing in on which organs and tissues may be involved. The quadrants are referred to as the left lower quadrant, left upper quadrant, right upper quadrant and right lower quadrant. These terms are not used in comparative anatomy, since most other animals do not stand erect. The left lower quadrant includes the left iliac fossa and half of the flank. The equivalent in other animals is ''left posterior quadrant''. The left upper quadrant extends from the umbilical plane to the left ribcage. This is the ''left anterior quadrant'' in other animals. The right upper quadrant extends from umbilical plane to the right ribcage. The equivalent in other animals is ''right anterior quadrant''. The right lower quadrant exten ...

Galactic Quadrant
A galactic quadrant, or quadrant of the Galaxy, is one of four circular sectors in the division of the Milky Way Galaxy. Quadrants in the galactic coordinate system In actual astronomical practice, the delineation of the galactic quadrants is based upon the galactic coordinate system, which places the Sun as the pole of the mapping system. The Sun is used instead of the Galactic Center for practical reasons since all astronomical observations (by humans) to date have been based on Earth or within the Solar System. Delineation Quadrants are described using ordinals—for example, "1st galactic quadrant" "second galactic quadrant," or "third quadrant of the Galaxy."M. Lampton ''et al''An All-Sky Catalog of Faint Extreme Ultraviolet Sources''The Astrophysical Journal Supplement Series ''. 1997 Viewing from the north galactic pole with 0 degrees (°) as the ray that runs starting from the Sun and through the galactic center, the quadrants are as follows (where is galactic l ...

Quadrant (solid Geometry)
In technical drawing and computer graphics, a multiview projection is a technique of illustration by which a standardized series of orthographic projection, orthographic two-dimensional pictures are constructed to represent the form of a three-dimensional object. Up to six pictures of an object are produced (called ''primary views''), with each projection plane parallel to one of the coordinate axes of the object. The views are positioned relative to each other according to either of two schemes: ''first-angle'' or ''third-angle'' projection. In each, the appearances of views may be thought of as being ''projected'' onto planes that form a six-sided box around the object. Although six different sides can be drawn, ''usually'' three views of a drawing give enough information to make a three-dimensional object. These views are known as ''front view'', ''top view'' and ''end view''. Other names for these views include ''plan'', ''elevation'' and ''section''. When the plane or axis of ...

Rating Percentage Index
The rating percentage index, commonly known as the RPI, is a quantity used to rank sports teams based upon a team's wins and losses and its strength of schedule. It is one of the sports rating systems by which NCAA basketball, baseball, softball, hockey, soccer, lacrosse, and volleyball teams are ranked. This system was in use from 1981 through 2018 to aid in the selecting and seeding of teams appearing in the NCAA Division I men's basketball tournament as well as in the women's tournament from its inception in 1982 through 2020. During the 2018 offseason, the NCAA announced that the RPI would no longer be used in the selection process for the Division I men's basketball tournament. Effective immediately, it was replaced with the NCAA Evaluation Tool (NET). In its current formulation, the index comprises a team's winning percentage (25%), its opponents' winning percentage (50%), and the winning percentage of those opponents' opponents (25%). The opponents' winning percentage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadrant (instrument)
A quadrant is an instrument used to measure angles up to 90°. Different versions of this instrument could be used to calculate various readings, such as longitude, latitude, and time of day. Its earliest recorded usage was in ancient India in Rigvedic times by Rishi Atri to observe a solar eclipse. It was then proposed by Ptolemy as a better kind of astrolabe. Several different variations of the instrument were later produced by medieval Muslim astronomers. Mural quadrants were important astronomical instruments in 18th-century European observatories, establishing a use for positional astronomy. Etymology The term ''quadrant'', meaning one fourth, refers to the fact that early versions of the instrument were derived from astrolabes. The quadrant condensed the workings of the astrolabe into an area one fourth the size of the astrolabe face; it was essentially a quarter of an astrolabe. History During Rigvedic times in ancient India, quadrants called 'Tureeyam's were use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Address (geography)
An address is a collection of information, presented in a mostly fixed format, used to give the location of a building, apartment, or other structure or a plot of land, generally using border, political boundaries and street names as references, along with other identifiers such as house number, house or apartment numbers and organization name. Some addresses also contain special codes, such as a postal code, to make identification easier and aid in the routing of mail. Addresses provide a means of physically locating a building. They are used in identifying buildings as the end points of a Mail, postal system and as parameters in statistics collection, especially in census-taking and the insurance industry. Address formats are different in different places, and unlike latitude and longitude coordinates, there is no simple mapping from an address to a location. History Until the 18th and 19th centuries, most houses and buildings were not numbered. Street naming and numberin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadrant (plane Geometry)
The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants, each bounded by two half-axes. These are often numbered from 1st to 4th and denoted by Roman numerals: I (where the signs of the (''x''; ''y'') coordinates are I (+; +), II (−; +), III (−; −), and IV (+; −). When the axes are drawn according to the mathematical custom, the numbering goes counter-clockwise starting from the upper right ("northeast") quadrant. Mnemonic In the above graphic, the words in quotation marks are a mnemonic A mnemonic ( ) device, or memory device, is any learning technique that aids information retention or retrieval (remembering) in the human memory for better understanding.

Quadrant (motorcycles)
Quadrant was one of the earliest British motorcycle manufacturers, established in Birmingham in 1901. Famous for their big singles, Quadrant pioneered many innovations that proved important for motorcycle development but struggled after the First World War and the company was wound up in 1928. History Founded by Walter and William Lloyd in 1883 as a company to make bicycles and tricycles, Quadrant developed some of the first motorcycles in 1901. The first Quadrant motorcycle was fitted with the then very popular Minerva "clip-on" engine. They also made powered tricycles in 1902. Walter took out a patent in 1902 for an 'all-in-one' control lever to raise the exhaust valve, control the ignition switch and operate the throttle and the ignition advance. By 1902 the Quadrant Cycle Co was making their own engines, their advert claiming "The engine and carburettor throughout, as also the bicycle, are made in our own Works". These were ahead of their time as the engines were not ju ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
