Compound (linguistics)
In linguistics, a compound is a lexeme (less precisely, a word or sign) that consists of more than one stem. Compounding, composition or nominal composition is the process of word formation that creates compound lexemes. Compounding occurs when two or more words or signs are joined to make a longer word or sign. A compound that uses a space rather than a hyphen or concatenation is called an open compound or a spaced compound; the alternative is a closed compound. The meaning of the compound may be similar to or different from the meaning of its components in isolation. The component stems of a compound may be of the same part of speech—as in the case of the English word ''footpath'', composed of the two nouns ''foot'' and ''path''—or they may belong to different parts of speech, as in the case of the English word ''blackbird'', composed of the adjective ''black'' and the noun ''bird''. With very few exceptions, English compound words are stressed on their first compo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyhedral Compound
In geometry, a polyhedral compound is a figure that is composed of several polyhedra sharing a common centre. They are the three-dimensional analogs of polygonal compounds such as the hexagram. The outer vertices of a compound can be connected to form a convex polyhedron called its convex hull. A compound is a facetting of its convex hull. Another convex polyhedron is formed by the small central space common to all members of the compound. This polyhedron can be used as the core for a set of stellations. Regular compounds A regular polyhedral compound can be defined as a compound which, like a regular polyhedron, is vertex-transitive, edge-transitive, and face-transitive. Unlike the case of polyhedra, this is not equivalent to the symmetry group acting transitively on its flags; the compound of two tetrahedra is the only regular compound with that property. There are five regular compounds of polyhedra: Best known is the regular compound of two tetrahedra, oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compounding
In the field of pharmacy, compounding (performed in compounding pharmacies) is preparation of a custom formulation of a medication to fit a unique need of a patient that cannot be met with commercially available products. This may be done for medical reasons, such as administration in a different format (ex: tablet to liquid), to avoid a non-active ingredient the patient is allergic to, or to provide an exact dose that isn't commercially available. Medically necessary compounding is referred to as "traditional" compounding. It may also be done for medically optional reasons, such as preference of flavor or texture, or dietary restrictions. Hospital pharmacies typically engage in compounding medications for intravenous administration, whereas outpatient or community pharmacies typically engage in compounding medications for oral or topical administration. Due to the rising cost of compounding and drug shortages, some hospitals outsource their compounding needs to large-scale c ...

Chemical Compound
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A compound can be transformed into a different substance by a chemical reaction, which may involve interactions with other substances. In this process, bonds between atoms may be broken and/or new bonds formed. There are four major types of compounds, distinguished by how the constituent atoms are bonded together. Molecular compounds are held together by covalent bonds; ionic compounds are held together by ionic bonds; intermetallic compounds are held together by metallic bonds; coordination complexes are held together by coordinate covalent bonds. Non-stoichiometric compounds form a disputed marginal case. A chemical formula specifies the number of atoms of each element in a compound molecule, usi ...

Compound Engine
A compound engine is an engine that has more than one stage for recovering energy from the same working fluid, with the exhaust from the first stage passing through the second stage, and in some cases then on to another subsequent stage or even stages. Originally invented as a means of making steam engines more efficient, the compounding of engines by use of several stages has also been used on internal combustion engines and continues to have niche markets there. The stages of a compound engine may be either of differing or of similar technologies, for example: * In a turbo-compound engine, the exhaust gas from the cylinders passes through a turbine, the two stages being dissimilar. * In a compound steam locomotive, the steam passes from the high-pressure cylinder or cylinders to the low-pressure cylinder or cylinders, the two stages being similar. * In a triple-expansion steam engine, the steam passes through three successive cylinders of increasing size and decreasing pressu ...

Compound Bow
In modern archery, a compound bow is a bow that uses a levering system, usually of cables and pulleys, to bend the limbs. In general, compound bows are widely used in target practice and hunting. The pulley/cam system grants the user a mechanical advantage, and so the limbs of a compound bow are much stiffer than those of a recurve bow or longbow. This rigidity makes the compound bow more energy-efficient than other bows, as less energy is dissipated in limb movement. The higher-rigidity, higher-technology construction also improves accuracy by reducing the bow's sensitivity to changes in temperature and humidity. The pulley/cam system also confers a benefit called "let-off." As the string is drawn back, the cams rotate. The cams are eccentric rather than round, and so their effective radius changes as they rotate. Each of a compound bow's two cams features two tracks: an inner track which connects to the opposite limb or opposite cam through cables, and an outer track thro ...

Compound (fortification)
In military science, a compound is a type of fortification made up of walls or fences surrounding several buildings in the center of a large piece of land. The walls can either serve the purpose of being tall, thick, and impenetrable, in which case they would be made of wood, stone, or some other like substance; or dangerous to attempt to scale, in which case they could be made of barbed wire or electrified. Compounds can be designed to double as living spaces and military structures in the middle of hostile territory or as a military area within a country's territory; they are also used by those who want to protect against threats to themselves or their property. A number of survivalists own fortified compound-like structures as a means of protection in case civilization breaks down or their government becomes abusive. The term ''compound'' is also used to refer to an unfortified enclosure, especially in Africa and Asia. See compound (enclosure). Specific group usage Insurgent ...

Turbo-compound Engine
A turbo-compound engine is a reciprocating engine that employs a turbine to recover energy from the exhaust gases. Instead of using that energy to drive a turbocharger as found in many high-power aircraft engines, the energy is instead sent to the output shaft to increase the total power delivered by the engine. The turbine is usually mechanically connected to the crankshaft, as on the Wright R-3350 Duplex-Cyclone, but electric and hydraulic power recovery systems have been investigated as well. As this recovery process does not increase fuel consumption, it has the effect of reducing the specific fuel consumption, the ratio of fuel use to power. Turbo-compounding was used for commercial airliners and similar long-range, long-endurance roles before the introduction of turbojet engines. Examples using the Duplex-Cyclone include the Douglas DC-7B and Lockheed L-1049 Super Constellation, while other designs did not see production use. Concept Most piston engines have a hot e ...

The Compound (book)
''The Compound'' is a 2008 fictional young adult novel by S. A. Bodeen. The book was first released on April 29, 2008, through Feiwel & Friends and centers upon a young man named Eli who has been living in a compound for six years. Bodeen came up with the idea of including cannibalism in the novel after watching a television show where "a dinosaur fed a favorite offspring the bodies of its less fortunate brothers and sisters." Synopsis Eli Yanakakis is a teenage boy who has been living in an underground compound for the past 6 years since he was 9. His father, the exceedingly wealthy Rex Yanakakis, built it in anticipation of a world-shattering nuclear attack. The facility is fully furnished and contains everything from a movie theater to an extensive library. It even has the capability to raise livestock, enabling the Yanakakis family to maintain a stable food supply for at least fifteen years, the time it would take for conditions outside the compound to return to habitable l ...

Compound Sentence (linguistics)
In grammar, sentence and clause structure, commonly known as sentence composition, is the classification of sentences based on the number and kind of clauses in their syntactic structure. Such division is an element of traditional grammar. Typology of clauses In standard English, sentences are composed of five ''clause'' patterns : # Subject + Verb (intransitive)''Example:'' She runs. # Subject + Verb (transitive) + Object''Example:'' She runs the meeting. # Subject + Verb (linking) + Subject Complement (adjective, noun, pronoun)''Example:'' Abdul is happy. Jeanne is a person. I am her. # Subject + Verb (transitive) + Indirect Object + Direct Object''Example:'' She made me a pie.This clause pattern is a derivative of S+V+O, transforming the object of a preposition into an indirect object of the verb, as the example sentence in transformational grammar is actually "She made a pie for me". # Subject + Verb (transitive) + Object + Object Complement''Example:'' They made him happy. ...

Compound Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper ( adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs li ...

Compound (music)
In music, metre ( Commonwealth spelling) or meter ( American spelling) refers to regularly recurring patterns and accents such as bars and beats. Unlike rhythm, metric onsets are not necessarily sounded, but are nevertheless implied by the performer (or performers) and expected by the listener. A variety of systems exist throughout the world for organising and playing metrical music, such as the Indian system of ''tala'' and similar systems in Arabic and African music. Western music inherited the concept of metre from poetry, where it denotes: the number of lines in a verse; the number of syllables in each line; and the arrangement of those syllables as long or short, accented or unaccented. The first coherent system of rhythmic notation in modern Western music was based on rhythmic modes derived from the basic types of metrical unit in the quantitative metre of classical ancient Greek and Latin poetry. Later music for dances such as the pavane and galliard consisted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
