Trough (meteorology)
A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft. Near-surface troughs sometimes mark a weather front associated with clouds, showers, and a wind direction shift. Upper-level troughs in the jet stream (as shown in diagram) reflect cyclonic filaments of vorticity. Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there. Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions mark troughs by a line. In the United States, a trough may be marked as a dashed line or bold line. In the UK, Ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watering Trough
A watering trough (or artificial watering point) is a man-made or natural receptacle intended to provide drinking water to animals, livestock on farms or ranches or wild animals. History In Australia, the watering trough is established so that sheep, cattle and other domesticated animals can drink, but native species such as kangaroos may be attracted. To reduce this, some water troughs are designed to reduce their use of the trough or exclude them from that use. One design is the "Finlayson Trough", which uses a low-lying electrified wire that sheep usually step over but kangaroos cannot. Watering troughs were very common in many towns and cities as a means for horses to drink while they were tethered to a post. In 1927 animal lovers, Annis and George Bills, funded the building of up to 500 watering troughs in Australia, Ireland, England and the United States. Many can still be seen today inscribed with ''Donated by Annis and George Bills Australia''. Nowadays, manufa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bread Trough
A bread trough, dough trough or kneading trough, sometimes referred to as artesa, is a rectangular receptacle with a shallow basin, and a traditional kneading tool used for the making of dough. The wooden form has been used in Europe for centuries in breadmaking. Kneading-trough A kneading trough ( ''mishʾereth'') is a term for the vessel in which dough, after being mixed and leavened was left to swell or ferment (; ; ). The dough in the vessels at the time of The Exodus was still unleavened, because the people were compelled to withdraw in haste.((Eastons)) The first citation of kneading-trough in the Oxford English Dictionary is Chaucer, The Miller's Tale, 1386. Flour was not stored, perhaps for fear of insect infestation, but kneaded into dough and baked into the bread without delay. Kneading-troughs in the Miller's Tale are big enough for people to sleep in and may be used as floating rafts. Other uses Mechanization in bakeries and new technologies in bread ovens hav ...

Trough Level
In medicine and pharmacology, a trough level or trough concentration (Ctrough) is the concentration reached by a drug immediately before the next dose is administered,AGAH working group Pharmacokinetics, 2004. often used in therapeutic drug monitoring. The name comes from the idea that on a graph of concentration versus time, the line forms a U-shaped trough at the lowest region, before a new sends it higher again. The usual criterion is concentration in the |
Trough (food)
__NOTOC__ A manger or trough is a rack for fodder, or a structure or feeder used to hold food for animals. The word comes from the Old French ''mangier'' (meaning "to eat"), from Latin ''mandere'' (meaning "to chew"). Mangers are mostly used in livestock raising and generally found at stables and farmhouses. They are also used to feed wild animals, e.g., in nature reserves. A similar trough providing drinking water for domestic or non-domestic animals is a watering trough and may be part of a larger watering structure called abreuvoir. The manger in Christianity The manger is also associated with nativity scenes where Mary and Joseph, forced by necessity to stay in a room for animals instead of a guest room, used a manger as a makeshift crib for the Baby Jesus.

Trough (geology)
In geology, a trough is a linear structural depression that extends laterally over a distance. Although it is less steep than a trench, a trough can be a narrow basin or a geologic rift. These features often form at the rim of tectonic plates. There are various oceanic troughs on the ocean floors. Examples of oceanic troughs * Benue Trough * Cayman Trough * Kings Trough * Hesperides Trough * Nankai Trough * Northumberland Trough * Okinawa Trough in the East China Sea * Rockall Trough and others along the rift of the mid-oceanic ridge A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about and rises about above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a diverge ... * Salton Trough * South Shetland Trough * Suakin TroughDinwiddie, Robert et al.

Trough (physics)
A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle. When the crests and troughs of two sine waves of equal amplitude and frequency intersect or collide, while being in phase with each other, the result is called ''constructive'' interference and the magnitudes double (above and below the line). When in antiphase – 180° out of phase – the result is ''destructive'' interference: the resulting wave is the undisturbed line having zero amplitude. See also * Crest factor * Superposition principle * Wave In physics, mathematics, and related fields, a wave is a propagating dynamic disturbance (change from equilibrium) of one or more quantities. Waves can be periodic, in which case those quantities oscillate repeatedly about an equilibrium (r ... References *, 704 pages. W ...

Trough (economics)
In economics, a trough is a low turning point or a local minimum of a business cycle. The time evolution of many economics variables exhibits a wave-like behavior with local maxima (peaks) followed by local minima (troughs). A business cycle may be defined as the period between two consecutive peaks. The period of the business cycle in which real GDP is increasing is called the expansion, in which the real GDP moves from the trough towards the peak. References Business cycle {{Business-stub ...

Political Corruption
Political corruption is the use of powers by government officials or their network contacts for illegitimate private gain. Forms of corruption vary, but can include bribery, lobbying, extortion, cronyism, nepotism, parochialism, patronage, influence peddling, graft, and embezzlement. Corruption may facilitate criminal enterprise such as drug trafficking, money laundering, and human trafficking, though it is not restricted to these activities. Misuse of government power for other purposes, such as repression of political opponents and general police brutality, is also considered political corruption. Over time, corruption has been defined differently. For example, in a simple context, while performing work for a government or as a representative, it is unethical to accept a gift. Any free gift could be construed as a scheme to lure the recipient towards some biases. In most cases, the gift is seen as an intention to seek certain favors such as work promotion, tipping in ...

Crony Capitalism
Crony capitalism, sometimes called cronyism, is an economic system in which businesses thrive not as a result of free enterprise, but rather as a return on money amassed through collusion between a business class and the political class. This is often achieved by the manipulation of relationships with state power by business interests rather than unfettered competition in obtaining permits, government grants, tax breaks, or other forms of state intervention over resources where business interests exercise undue influence over the state's deployment of public goods, for example, mining concessions for primary commodities or contracts for public works. Money is then made not merely by making a profit in the market, but through profiteering by rent seeking using this monopoly or oligopoly. Entrepreneurship and innovative practices which seek to reward risk are stifled since the value-added is little by crony businesses, as hardly anything of significant value is created by them, wit ...

Nepotism
Nepotism is an advantage, privilege, or position that is granted to relatives and friends in an occupation or field. These fields may include but are not limited to, business, politics, academia, entertainment, sports, fitness, religion, and other activities. The term originated with the assignment of nephews to important positions by Catholic popes and bishops. Nepotism has been criticized since the ancient times by several philosophers, including Aristotle, Valluvar, and Confucius, condemning it as both evil and unwise. Origins The term comes from Italian word ''nepotismo'',"Nepotism." Dictionary.com. Retrieved 20 June 2013. which is based on Latin root ''nepos'' meaning nephew. Since the ...

Public Economics
Public economics ''(or economics of the public sector)'' is the study of government policy through the lens of economic efficiency and equity. Public economics builds on the theory of welfare economics and is ultimately used as a tool to improve social welfare. Welfare can be defined in terms of well-being, prosperity, and overall state of being. Public economics provides a framework for thinking about whether or not the government should participate in economic markets and if so to what extent it should do so. Microeconomic theory is utilized to assess whether the private market is likely to provide efficient outcomes in the absence of governmental interference; this study involves the analysis of government taxation and expenditures. This subject encompasses a host of topics notably market failures such as, public goods, externalities and Imperfect Competition, and the creation and implementation of government policy. Broad methods and topics include: * the theory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
