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 * Salton Trough * South Shetland Trough * Suakin TroughDinwiddie, Robert et al.

Geologically, ocean basins are large geologic basins that are below sea level. Most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Troff
troff (), short for "typesetter roff", is the major component of a document processing system developed by Bell Labs for the Unix operating system. troff and the related nroff were both developed from the original roff. While nroff was intended to produce output on terminals and line printers, troff was intended to produce output on typesetting systems, specifically the Graphic Systems CAT that had been introduced in 1972. Both used the same underlying markup language and a single source file could normally be used by nroff or troff without change. ''troff'' features commands to designate fonts, spacing, paragraphs, margins, footnotes and more. Unlike many other text formatters, ''troff'' can position characters arbitrarily on a page, even overlapping them, and has a fully programmable input language. Separate preprocessors are used for more convenient production of tables, diagrams, and mathematics. Inputs to troff are plain text files that can be created by any text edit ...

Trow
A trow was a type of cargo boat found in the past on the rivers Severn and Wye in Great Britain and used to transport goods. Features The mast could be taken down so that the trow could go under bridges, such as the bridge at Worcester and the many bridges up and downstream. The mast was stepped in a three sided frame open at the rear but closed with an iron pin or rope lashing. From the top of the mast a forestay ran down to the bow winch. To lower the mast the pin was removed and the winch slackened off to let the mast fall towards the stern. The reverse operation pulled the mast up. Despite their flat-bottomed hull form which made volume available for their load and permitted drying out on muddy banks in the tidal area where they operated, Trows were seaworthy. For example, with an added keel the Droitwich Trow ''Hastings'' is recorded as taking 90 tons of salt from Droitwich to France across the English Channel. The flat-bottomed trows sailed on the sea by hauling a lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inkwell
An inkwell is a small jar or container, often made of glass, porcelain, silver, brass, or pewter, used for holding ink in a place convenient for the person who is writing. The artist or writer dips the brush, quill, or dip pen into the inkwell as needed or uses the inkwell as the source for filling the reservoir of a fountain pen. An inkwell usually has a lid to prevent contamination, evaporation, accidental spillage, and excessive exposure to air. A type known as the travelling inkwell was fitted with a secure, screw lid so a traveller could carry a supply of ink in their luggage without the risk of leakage. Origins The inkwell's origins may be traced back to Ancient Egypt where scribes would write on papyrus. Knowledge of hieroglyphs was at the time highly restricted. Only scribes knew the full array of hieroglyphs and would write on the behalf of their employers, usually the pharaoh. After Rome invaded Egypt, inkwells became more popular in Italy as a larger percentage of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Trough
The Trough is a 6-mile long wooded gorge carved by the South Branch Potomac River (SBPR) and situated in the Allegheny Mountains of Hampshire and Hardy Counties, West Virginia, USA. The area was the site of a 1756 skirmish of the French and Indian War, known as the "Battle of the Trough". The steep slopes of the Trough are forested primarily with oaks, hickories, Virginia pine, large quantities of paw paw, with several rock outcrops visible on both sides. The two wooded ridges that define The Trough make it inaccessible from either side. Entry into The Trough is only by the South Branch Valley Railroad (the SVBR, along the foot of Mill Creek Mountain), by boat, or on foot. Geography The Trough is a narrow valley bounded by Mill Creek Mountain to its west and Sawmill Ridge (1,716 feet) to its east with the SBPR flowing in between them. The Trough's opening is located at the southern slopes of Mill Creek Mountain and Sawmill Ridge at McNeill in Hardy County. Mill Creek Mountai ...

Sleightholme Beck Gorge - The Troughs
Sleightholme is a secluded hamlet on a dead end road in County Durham, England. It lies beside Sleightholme Beck, a tributary of the River Greta. The nearest town is Bowes, 4 miles away. The name, first recorded in 1254, is believed to come from the Old Norse ''sletta holmr'', meaning "flat ground near water". The place was historically in the North Riding of Yorkshire, and was transferred to County Durham in 1974. The Pennine Way passes through Sleightholme. Below the hamlet Sleightholme Beck passes through a narrow valley, known as The Troughs, which is a Site of Special Scientific Interest A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of ....

Battle Of The Trough
The Battle of the Trough (March or April 1756) was a skirmish of the early French and Indian War (1754–63) fought between Native Americans and Anglo-American settlers in the valley of the South Branch Potomac River in what is now northern Hardy County, West Virginia, USA. Background After the defeat of General Edward Braddock at the Battle of the Monongahela (9 July 1755), the white settlers of the Allegheny Mountains were largely unprotected from a series of Shawnee and Delaware Indian raids. In October, in an effort to provide some respite, two forts were raised in the South Branch Valley. By the end of the year, the Virginia Regiment had increased its numbers by several hundred troops and began to temporarily man some of these settler forts. Shortly after the new year, a new commander of the Regiment — the 24-year-old Colonel George Washington — ordered Captain Thomas Waggener to leave Fort Cumberland with his company and proceed up the South Branch. His orders directed ... [...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, manufac ... [...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 ha ...

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, Hong Kong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 and applic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
