Sail

A sail is a catchment device designed to receive and redirect a force upon a generous surface area. Traditionally, the surface was engineered of woven fabric and supported by a mast, whose purpose is to propel a sailing vessel. Sails may be configured in many ways to include traditionally understood maritime purposes, as well as land vehicles and solar collection purposes. The rich encyclopedic history of maritime sails suggests alternative uses of the technology well documented.

History of sails

Archaeological studies of the Cucuteni-Trypillian culture ceramics show use of sailing boats from the sixth millennium onwards. Excavations of the Ubaid period (c. 6000 -4300 BC) in Mesopotamia provides direct evidence of sailing boats. Sails from ancient Egypt are depicted around 3200 BCE, where reed boats sailed upstream against the River Nile's current. Ancient Sumerians used square rigged sailing boats at about the same time, and it is believed they established sea trading routes as far away as the Indus valley. The proto-Austronesian words for sail, lay(r), and other rigging parts date to about 3000 BCE when this group began their Pacific expansion.Greeks and Phoenicians began trading by ship by around 1,200 BCE.

Sail (Lake District)

Sail is a hill in the English Lake District, lying between Derwentwater and Crummock Water.

Topography

The North Western Fells occupy the area between the rivers Derwent and Cocker, a broadly oval swathe of hilly country, elongated on a north-south axis. Two roads cross from east to west, dividing the fells into three convenient groups. The central sector, rising between Whinlatter Pass and Newlands Pass, includes Sail. The highest ground in the North Western Fells is an east-west ridge in this central sector, beginning with Grasmoor above Crummock Water and then gradually descending eastwards over Crag Hill, Sail, Scar Crags and Causey Pike.

Sail is in every sense a satellite of Crag Fell, although having sufficient prominence to be listed as a Hewitt. From the summit of Crag Hill the eastward ridge narrows between opposing walls of crag. This rocky crest is The Scar, the depression being at around 2,425 ft. The roughness decreases as the rounded top of Sail is reached, and the ridge then turns east north east. A further depression at 2,015 ft leads to the summit of Scar Crags. This col is unnamed on maps of the Ordnance Survey, but Alfred Wainwright termed it Sail Pass in his influential Pictorial Guide to the Lakeland Fells

Sail (anatomy)

A sail is a large, flattish protrusion from the back of an animal colinear with the spine. Many extinct species of amphibians and reptiles have very extended neural spines growing from their back vertebrae. These are thought to have supported a sail. Paleontologists have proposed many ways in which the sail could have functioned in life.

Function

Many suggestions have been made for the function of the sail. The consensus amongst modern scholars is that, at least for the pelycosaurs, the sail was used for thermoregulation.

Thermoregulation

The structure may have been used for thermoregulation. The base of the spines have a channel which it is proposed contained a blood vessel supplying abundant blood to the sail. The animal could have used the sail's large surface area to absorb heat from the sun in the morning. As ectotherms they required heat from an external source before their muscles would start to function properly. A predator would thus have an advantage over its slower moving prey. The sail could be used in reverse if the animal was overheating. By standing in the shade, the sail would radiate heat outwards.

Guanajuato

Guanajuato (Spanish pronunciation: [gwanaˈxwato]), officially Free and Sovereign State of Guanajuato (Spanish: Estado Libre y Soberano de Guanajuato), is one of the 31 states which, with the Federal District, are the 32 Federal entities of Mexico. It is divided into 46 municipalities and its capital city is Guanajuato. The largest city in the state is León.

It is located in North-Central Mexico. It is bordered by the states of Jalisco to the west, Zacatecas to the northwest, San Luis Potosí to the north, Querétaro to the east and Michoacán to the south. It covers an area of 30,608 km² (11,818 sq mi).

Guanajuato is located between the arid north of the country and the lusher south, and it is geographically part of the Trans-Mexican Volcanic Belt, the Mexican Plateau and the Sierra Madre Oriental. It was initially settled by the Spanish in the 1520s due to mineral deposits found around the now capital city of Guanajuato, but areas such as the Bajío region also became important for agriculture and livestock. Mining and agriculture have been the traditional mainstays of the state's economy, but today, about 30% of the state's GDP is accounted for by industry, which includes metals, automobiles, leather goods, processed foods and more.

Ferrari 250 GTO

The Ferrari 250 GTO is a racing GT car which was produced by Ferrari from 1962 to 1964 for homologation into the FIA's Group 3 Grand Touring Car category. In May 2012 the 1962 250 GTO made for Stirling Moss became the world's most expensive car in history, selling in a private transaction for $38,115,000 to US communications magnate Craig McCaw. In October 2013, Connecticut-based collector Paul Pappalardo sold chassis number 5111GT to an unnamed buyer for a new record, somewhere within the $38 million range. The numerical part of its name denotes the displacement in cubic centimeters of each cylinder of the engine, whilst GTO stands for "Gran Turismo Omologato",Italian for "Grand Touring Homologated." When new, the GTO cost $18,000 in the United States, and buyers had to be personally approved by Enzo Ferrari and his dealer for North America, Luigi Chinetti.

In total, 39 250 GTOs were manufactured between 1962 and 1964. This includes 33 cars with 1962-63 bodywork (Series I), three cars with 1964 (Series II) bodywork similar to the Ferrari 250 LM and three "330 GTO" specials with a larger engine. Four of the older 1962-1963 (Series I) cars were retrofitted in 1964 with an updated (Series II) body.

GTO (song)

"GTO" is a song by Sinitta. It was released in 1987 as the fifth single from her self-titled debut album. Produced by Stock Aitken Waterman, the song was successful in the UK where it was a top 20 hit (peaking at #15).
