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, US. The area was the site of a 1756 skirmish of the French and Indian War The French and Indian War, 1754 to 1763, was a colonial conflict in North America between Kingdom of Great Britain, Great Britain and Kingdom of France, France, along with their respective Native Americans in the United States, Native American ..., 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 ...

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 * Hesperides Trough * Kings Trough * Mariana 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.

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 direc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trough (meteorology)
A trough is an elongated region of relatively low atmospheric pressure without a closed Isobar (meteorology), isobaric contour that would define it as a Low-pressure area, low pressure area. Since low pressure implies a low Geopotential height, height on a pressure surface, Valley, troughs and Ridge (meteorology), ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft, at altitude. 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 rotation, 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 ...

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, manufactu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ....

Water Trough
A water trough (British English, British terminology), or track pan (American English, American terminology), is a device to enable a steam locomotive to replenish its water supply while in motion. It consists of a long trough filled with water, lying between the rails. When a steam locomotive passes over the trough, a water scoop can be lowered, and the speed of forward motion forces water into the scoop, up the scoop pipe and into the tanks or tender (rail), locomotive tender. Origin Steam locomotives consume a considerable amount of water, and the tender or side tanks need to be replenished at intervals. Traditionally the engine water was replenished during station stops, but if it was desired to run long distances without stopping, the requirement to take water was a significant limitation. ''The Railway Magazine'' reported a development by John Ramsbottom (engineer), John Ramsbottom: Ramsbottom arranged some experiments and showed that the forward motion of a scoop in a ...

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 (software), roff. While nroff was intended to produce output on terminals and line printers, troff was intended to produce output on typesetting systems, specifically the CAT (phototypesetter), Graphic Systems CAT, which 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 fi ...

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 is a term for the vessel in which dough, after being mixed and leavened was left to swell or ferment. 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 have mostly relegated the artesa to either recycling or as a flowerpot, except in more traditional or rural areas. Some small bakeries continue to use them.''A Few Grea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trow
A trow was a type of cargo boat found in the past on the rivers River Severn, Severn and River Wye, Wye in Great Britain and used to transport goods. Features The Mast (sailing), mast could be taken down so that the trow could go under bridges, such as the bridge at Worcester, England, 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. ...
