Shipbuilding Companies Of Pakistan
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.

Hull (ship)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. ...

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] |

David O'Connor (Egyptologist)
David Bourke O'Connor (5 February 1938 – 1 October 2022) was an Australian-American Egyptologist who primarily worked in the fields of Ancient Egypt and Nubia. O'Connor is the Lila Acheson Wallace Professor Emeritus at New York University's Institute of Fine Art, the Curator Emeritus of the University of Pennsylvania's Egyptian Museum, and the director emeritus of the Abydos Archaeology expedition in Egypt. O'Connor is most well known for his work in the excavation of the ancient city of Abydos in Egypt since 1967. Early life Born in Sydney in 1938, O'Connor's interests in archaeology and ancient history originated when he was a child. His initial interest centred around the ancient civilization of Babylon. O'Connor built a replica of the city of Babylon out of bricks in a field adjacent to his home, and recreated the Fall of Babylon by setting the field alight during the height of the 1968-69 bushfires in New South Wales. Education O'Connor received a Bachelor of Arts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abydos, Egypt
Abydos ( ar, أبيدوس, Abīdūs or ; Sahidic cop, Ⲉⲃⲱⲧ ') is one of the oldest cities of ancient Egypt, and also of the eighth nome in Upper Egypt. It is located about west of the Nile at latitude 26° 10' N, near the modern Egyptian towns of El Araba El Madfuna and El Balyana. In the ancient Egyptian language, the city was called Abdju (''ꜣbḏw'' or ''AbDw''). The English name ''Abydos'' comes from the Greek , a name borrowed by Greek geographers from the unrelated city of Abydos on the Hellespont. Considered one of the most important archaeological sites in Egypt, the sacred city of Abydos was the site of many ancient temples, including Umm el-Qa'ab, a royal necropolis where early pharaohs were entombed. These tombs began to be seen as extremely significant burials and in later times it became desirable to be buried in the area, leading to the growth of the town's importance as a cult site. Today, Abydos is notable for the memorial temple of Seti I, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
