Shipbuilder
Shipbuilding is the construction of ships and other floating vessels. It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history. Shipbuilding and ship repairs, both commercial and military, are referred to as "naval engineering". The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking. History Pre-history The earliest known depictions (including paintings and models) of shallow-water sailing boats is from the 6th to 5th millennium BC of the Ubaid period of Mesopotamia. They were made from bundled reeds coated in bitumen and had bipod masts. They sailed in shallow coastal waters of the Persian Gulf. 4th millennium BC Ancient Egypt Evidence from Ancient Egypt shows that the early Egyptians knew how to assemble planks of wood into a ship hull as early as 3100 BC.

Shipyard
A shipyard, also called a dockyard or boatyard, is a place where ships are built and repaired. These can be yachts, military vessels, cruise liners or other cargo or passenger ships. Dockyards are sometimes more associated with maintenance and basing activities than shipyards, which are sometimes associated more with initial construction. The terms are routinely used interchangeably, in part because the evolution of dockyards and shipyards has often caused them to change or merge roles. Countries with large shipbuilding industries include Australia, Brazil, China, Croatia, Denmark, Finland, France, Germany, India, Ireland, Italy, Japan, the Netherlands, Norway, the Philippines, Poland, Romania, Russia, Singapore, South Korea, Sweden, Taiwan, Turkey, the United Arab Emirates, Ukraine, the United Kingdom, the United States and Vietnam. The shipbuilding industry is more fragmented in Europe than in Asia where countries tend to have fewer, larger companies. Many naval vessels ar ...

Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about the use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries. In 2012, roughly 1,250 ocean ships were broken down, and their average age was ...

Construction
Construction is a general term meaning the art and science to form objects, systems, or organizations,"Construction" def. 1.a. 1.b. and 1.c. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) Oxford University Press 2009 and comes from Latin ''constructio'' (from ''com-'' "together" and ''struere'' "to pile up") and Old French ''construction''. To construct is the verb: the act of building, and the noun is construction: how something is built, the nature of its structure. In its most widely used context, construction covers the processes involved in delivering buildings, infrastructure, industrial facilities and associated activities through to the end of their life. It typically starts with planning, financing, and design, and continues until the asset is built and ready for use; construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning.

Polynesia
Polynesia () "many" and νῆσος () "island"), to, Polinisia; mi, Porinihia; haw, Polenekia; fj, Polinisia; sm, Polenisia; rar, Porinetia; ty, Pōrīnetia; tvl, Polenisia; tkl, Polenihia (, ) is a subregion of Oceania, made up of more than 1,000 islands scattered over the central and southern Pacific Ocean. The indigenous people who inhabit the islands of Polynesia are called Polynesians. They have many things in common, including language relatedness, cultural practices, and traditional beliefs. In centuries past, they had a strong shared tradition of sailing and using stars to navigate at night. The largest country in Polynesia is New Zealand. The term was first used in 1756 by the French writer Charles de Brosses, who originally applied it to all the islands of the Pacific. In 1831, Jules Dumont d'Urville proposed a narrower definition during a lecture at the Geographical Society of Paris. By tradition, the islands located in the southern Pacific have also ...

Austronesian Peoples
The Austronesian peoples, sometimes referred to as Austronesian-speaking peoples, are a large group of peoples in Taiwan, Maritime Southeast Asia, Micronesia, coastal New Guinea, Island Melanesia, Polynesia, and Madagascar that speak Austronesian languages. They also include indigenous ethnic minorities in Vietnam, Cambodia, Myanmar, Thailand, Hainan, the Comoros, and the Torres Strait Islands. The nations and territories predominantly populated by Austronesian-speaking peoples are sometimes known collectively as Austronesia. Based on the current scientific consensus, they originated from a prehistoric seaborne migration, known as the Austronesian expansion, from pre- Han Taiwan, at around 1500 to 1000 BCE. Austronesians reached the northernmost Philippines, specifically the Batanes Islands, by around 2200 BCE. Austronesians used sails some time before 2000 BCE. In conjunction with their use of other maritime technologies (notably catamarans, outrigger boats, lashed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hor-Aha
Hor-Aha (or Aha or Horus Aha) is considered the second pharaoh of the First Dynasty of Egypt by some Egyptologists, while others consider him the first one and corresponding to Menes. He lived around the 31st century BC and is thought to have had a long reign. Identity Name The commonly used name ''Hor-Aha'' is a rendering of the pharaoh's Horus-name, an element of the royal titulary associated with the god Horus, and is more fully given as ''Horus-Aha'' meaning ''Horus the Fighter''. Manetho's record ''Aegyptiaca'' (translating to History of Egypt) lists his Greek name as Athothis, or "Athotís". For the Early Dynastic Period, the archaeological record refers to the pharaohs by their Horus-names, while the historical record, as evidenced in the Turin and Abydos king lists, uses an alternative royal titulary, the ''nebty''-name. The different titular elements of a pharaoh's name were often used in isolation, for brevity's sake, although the choice varied according to c ...

Khasekhemwy
Khasekhemwy (ca. 2690 BC; ', also rendered ''Kha-sekhemui'') was the last Pharaoh of the Second Dynasty of Egypt. Little is known about him, other than that he led several significant military campaigns and built the mudbrick fort known as Shunet El Zebib. His Horus name ' can be interpreted "The Two Powerful Ones Appear", but the name is recorded in many variants, such as ''Ḥr-Ḫꜥj-sḫm(Horus, he whose power appears)", '' ḫꜥj sḫm.wj ḫtp nṯrwj jm=f(the two powers appear in that the ancestors rest within him)"(etc.) Date of reign Khasekhemwy ruled for close to 18 years, with a ''floruit'' in the early 27th century BC. The exact date of his reign in Egyptian chronology is unclear but would fall roughly in between 2690–2670 BC. According to Toby Wilkinson's study of the Palermo Stone in ''Royal Annals of Ancient Egypt'', this near contemporary 5th dynasty document assigns Khasekhemwy a reign of 17.5 or nearly 18 full years. Wilkinson suggests that a reig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyperus Papyrus
''Cyperus papyrus'', better known by the common names papyrus, papyrus sedge, paper reed, Indian matting plant, or Nile grass, is a species of aquatic flowering plant belonging to the sedge family Cyperaceae. It is a tender herbaceous perennial, native to Africa, and forms tall stands of reed-like swamp vegetation in shallow water. Papyrus sedge (and its close relatives) has a very long history of use by humans, notably by the Ancient Egyptians (as it is the source of papyrus paper, one of the first types of paper ever made). Parts of the plant can be eaten, and the highly buoyant stems can be made into boats. It is now often cultivated as an ornamental plant. In nature, it grows in full sun, in flooded swamps, and on lake margins throughout Africa, Madagascar, and the Mediterranean countries. It has been introduced outside its range to tropical regions worldwide (such as the Indian subcontinent, South America, and the Caribbean). Description This tall, robust aquatic pl ...

Strap
A strap, sometimes also called strop, is an elongated wikt:flap, flap or ribbon, usually of leather or other flexible materials. Thin straps are used as part of clothing or baggage, or bedding such as a sleeping bag. See for example spaghetti strap, shoulder strap. A strap differs from a belt (clothing), belt mainly in that a strap is usually integral to the item of clothing; either can be used in combination with buckles. Straps are also used as fasteners to attach, secure, carry, or bind items, to objects, animals (for example a saddle on a horse) and people (for example a watch on a wrist), or even to tie down people and animals, as on an apparatus for corporal punishment. Occasionally a strap is specified after what it binds or holds, e.g. chin strap. Webbing is a particular type of strap that is a strong fabric woven as a flat strip or tube that is also often used in place of rope. Modern webbing is typically made from exceptionally high-strength material and is used in aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New York University
New York University (NYU) is a private research university in New York City. Chartered in 1831 by the New York State Legislature, NYU was founded by a group of New Yorkers led by then-Secretary of the Treasury Albert Gallatin. In 1832, the non-denominational all-male institution began its first classes near City Hall based on a curriculum focused on a secular education. The university moved in 1833 and has maintained its main campus in Greenwich Village surrounding Washington Square Park. Since then, the university has added an engineering school in Brooklyn's MetroTech Center and graduate schools throughout Manhattan. NYU has become the largest private university in the United States by enrollment, with a total of 51,848 enrolled students, including 26,733 undergraduate students and 25,115 graduate students, in 2019. NYU also receives the most applications of any private institution in the United States and admission is considered highly selective. NYU is organized int ...
