Submarine hull

A light hull (casing in British usage) of a submarine is the outer non-watertight hull which provides a hydrodynamically efficient shape. The pressure hull is the inner hull of a submarine; this holds the difference between outside and inside pressure.

Submarine hull

Modern submarines are usually cigar-shaped. This design, already visible on very early submarines is called a "teardrop hull", and was patterned after the bodies of whales. It significantly reduces the hydrodynamic drag on the sub when submerged, but decreases the sea-keeping capabilities and increases the drag while surfaced.

History

The concept of an outer hydrodynamically streamlined light hull separated from the inner pressure hull was first introduced in the early pioneering submarine Ictineo I designed by the Catalan inventor Narcís Monturiol i Estarriol in 1859. However, when military submarines entered service in the early 1900s, the limitations of their propulsion systems forced them to operate on the surface most of the time; their hull designs were a compromise, with the outer hulls resembling a ship, allowing for good surface navigation, and a relatively streamlined superstructure to minimize drag under water. Because of the slow submerged speeds of these submarines, usually well below 10 knots (19 km/h), the increased drag for underwater travel by the conventional ship like outer hull was considered acceptable. Only late in World War II, when technology enhancements allowed faster and longer submerged operations and increased surveillance by enemy aircraft forced submarines to spend most of their times below the surface, did hull designs become teardrop shaped again, to reduce drag and noise. On modern military submarines the outer hull (and sometimes also the propeller) is covered with a thick layer of special sound-absorbing rubber, or anechoic plating, to make the submarine more difficult to detect by active and passive SONAR.

Hull, Quebec

Hull (French pronunciation: ​[ɔl]) is the central district and oldest part of the city of Gatineau, Quebec, Canada. It is located on the west bank of the Gatineau River and the north shore of the Ottawa River, directly opposite Ottawa. As part of the Canadian National Capital Region, it contains offices for twenty thousand civil servants. It is named after Kingston upon Hull in the United Kingdom.

History

Early history

Hull is a former municipality in the Province of Quebec and the location of the oldest non-native settlement in the National Capital Region. It was founded on the north shore of the Ottawa River in 1800 by Philemon Wright at the portage around the Chaudière Falls just upstream (or west) from where the Gatineau and Rideau Rivers flow into the Ottawa. Wright brought his family, five other families and twenty-five labourers and a plan to establish an agriculturally based community to what was a mosquito-infested wilderness. But soon after, Wright and his family took advantage of the large lumber stands and became involved in the timber trade. Originally the place was named Wright's Town, and the name Wrightville survives as the name of a neighborhood in Hull.

.travel

The domain name .travel is a top-level domain in the Domain Name System of the Internet. Its name suggests the intended and restricted use by travel agents, airlines, bed and breakfast operators, tourism bureaus, and others in the travel industry.

It is sponsored by Tralliance Registry Management Company (TRMC). Registrations are processed via accredited registrars.

History

The domain was approved by ICANN on April 8, 2005 as a sponsored TLD in the second group of new TLD applications evaluated in 2004. TheGlobe.com acquired Tralliance Corporation, the operator of .travel, on May 9, 2005.

The official launch began in October 2005, with a screening process to determine eligibility to register domains in each of three monthly groups for October, November and December. Open registrations began in January 2006. Governments were given priority registration for geographic place names from July 2005 to December 21, 2007.

A 2006 proposal that a wildcard DNS record point all unused *.travel domains to Tralliance's search.travel site was rejected by ICANN due to technical considerations.

Travel

Travel is the movement of people between relatively distant geographical locations, and can involve travel by foot, bicycle, automobile, train, boat, airplane, or other means, with or without luggage, and can be one way or round trip. Travel can also include relatively short stays between successive movements.

Etymology

The origin of the word "travel" is most likely lost to history. The term "travel" may originate from the Old French word travail. According to the Merriam Webster dictionary, the first known use of the word travel was in the 14th century. It also states that the word comes from Middle English travailen, travelen (which means to torment, labor, strive, journey) and earlier from Old French travailler (which means to work strenuously, toil). In English we still occasionally use the words travail and travails, which mean struggle. According to Simon Winchester in his book The Best Travelers' Tales (2004), the words travel and travail both share an even more ancient root: a Roman instrument of torture called the tripalium (in Latin it means "three stakes", as in to impale). This link reflects the extreme difficulty of travel in ancient times. Also note the torturous connotation of the word "travailler." Today, travel may or may not be much easier depending upon the destination you choose (i.e., Mt. Everest, the Amazon rainforest), how you plan to get there (tour bus, cruise ship, or oxcart), and whether or not you decide to "rough it (see extreme tourism and adventure travel). "There's a big difference between simply being a tourist and being a true world traveler," notes travel writer Michael Kasum. This is, however, a contested distinction as academic work on the cultures and sociology of travel has noted.
