Mortise And Tenon
A mortise and tenon (occasionally mortice and tenon) is a Woodworking joints, joint that connects two pieces of wood or other material. Woodworking, Woodworkers around the world have used it for thousands of years to join pieces of wood, mainly when the adjoining pieces connect at right angles, though it can be used to connect two work pieces at any angle. Mortise-and tenon-joints are simple, strong, and stable, and can be used in many projects and which give an attractive look. They are either glued or friction-fitted into place. This joint is difficult to make, because of the precise measuring and tight cutting required; as such, modern woodworkers often use machinery specifically designed to cut mortises and matching tenons quickly and easily. Still, many woodworkers cut them by hand in a traditional manner. There are many variations of this type of joint, but its basic structure has two components, the ''mortise'' hole and the ''tenon'' tongue. The tenon, formed on the end o ...

Fourth Dynasty Of Egypt
The Fourth Dynasty of ancient Egypt (notated Dynasty IV) is characterized as a "golden age" of the Old Kingdom of Egypt. Dynasty IV lasted from to c. 2498 BC. It was a time of peace and prosperity as well as one during which trade with other countries is officially documented. The Fourth Dynasty heralded the height of the pyramid-building age. The peaceful rule of the Third Dynasty of Egypt, Third Dynasty allowed artistic expressions to flourish. Building experiments done by King Sneferu led to the evolution of mastaba tombs into the smooth sided pyramids like those seen on the Giza Plateau. No other period in Egyptian history equaled the accomplishments achieved during the Fourth Dynasty.Egypt: Land and Lives of the Pharaohs Revealed, (2005), pp. 80–90, Global Book Publishing: Australia Rulers Summary of Listed Kings Sneferu Sneferu, lauded as "Bringer of Beauty", "Master of All Justice", and "Ruler of Lower and Upper Nile", was the first pharaoh of the fourt ...

Bone Chisel Reconstruction
A bone is a rigid organ that constitutes part of the skeleton in most vertebrate animals. Bones protect the various other organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility. Bones come in a variety of shapes and sizes and have complex internal and external structures. They are lightweight yet strong and hard and serve multiple functions. Bone tissue (osseous tissue), which is also called bone in the uncountable sense of that word, is hard tissue, a type of specialised connective tissue. It has a honeycomb-like matrix internally, which helps to give the bone rigidity. Bone tissue is made up of different types of bone cells. Osteoblasts and osteocytes are involved in the formation and mineralisation of bone; osteoclasts are involved in the resorption of bone tissue. Modified (flattened) osteoblasts become the lining cells that form a protective layer on the bone surface. The mineralised matrix ...

Sash Corner
A sash is a large and usually colorful ribbon or band of material worn around the human body, either draping from one shoulder to the opposing hip and back up, or else encircling the waist. The sash around the waist may be worn in daily attire, but the sash from shoulder to hip is worn on ceremonial occasions only. Ceremonial sashes are also found in a V-shaped format, draping straight from both shoulders down, intersecting and forming an angle over the chest or abdomen. Military use Old Europe In the mid-and late-16th century waist and shoulder sashes came up as a mark of (high) military rank or to show personal affection to a political party or nation. During the Thirty Years' War the distinctive sash colour of the House of Habsburg was red while their French opponents wore white or blue sashes and the Swedish voted for blue sashes. Beginning from the end of the 17th century, commissioned officers in the British Army wore waist sashes of crimson silk. The original office ...

Hull (watercraft)
A hull is the watertight body of a ship, boat, submarine, 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 (sailing), 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 bot ...

Shipbuilding
Shipbuilding is the construction of ships and other Watercraft, floating vessels. In modern times, 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. Until recently, with the development of complex non-maritime technologies, a ship has often represented the most advanced structure that the society building it could produce. Some key industrial advances were developed to support shipbuilding, for instance the sawing of timbers by Saw#Mechanically powered saws, mechanical saws propelled by windmills in Dutch shipyards during the first half of the 17th century. The design process saw the early adoption of the logarithm (invented in 1615) to generate the curves used to produce the shape of a hull (watercraft), hull, especially when scaling up these curves accurately in the mould Lofting, loft. Shipbuilding and ship repairs, both commercial an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loeb Classical Library
The Loeb Classical Library (LCL; named after James Loeb; , ) is a monographic series of books originally published by Heinemann and since 1934 by Harvard University Press. It has bilingual editions of ancient Greek and Latin literature, with the original Greek or Latin text on the left-hand page and a fairly literal translation on the facing page. History Under the inspiration drawn from the book series specializing in publishing classical texts exclusively in the original languages, such as the Bibliotheca Teubneriana, established in 1849 or the Oxford Classical Texts book series, founded in 1894, the Loeb Classical Library was conceived and initially funded by the Jewish-German-American banker and philanthropist James Loeb (1867–1933). The first volumes were edited by Thomas Ethelbert Page, W. H. D. Rouse, and Edward Capps, and published by William Heinemann, Ltd. (London) in 1912, already in their distinctive green (for Greek text) and red (for Latin) hardco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoenician Joints
A Phoenician joint () is a locked mortise and tenon wood joinery technique used in shipbuilding to fasten watercraft hulls. The locked (or pegged) mortise and tenon technique consists of cutting a mortise, or socket, into the edges of two planks and fastening them together with a rectangular wooden knob. The assembly is then locked in place by driving a dowel through one or more holes drilled through the mortise side wall and tenon. The Phoenicians pioneered the use of locked mortise and tenon joints in nautical joinery to secure the underwater planking of seagoing ships. The use of pegged mortises and tenons in shipbuilding spread westward from the Levantine littoral. Examples of the use of Phoenician joints in the ancient Mediterranean include the Uluburun ship, dated , and the Cape Gelidonya ship dated to . By the first millennium BC, Phoenician joints became a common edge-to-edge fastening method. Ancient Greek and Roman shipbuilders adopted the technique of Phoenician jo ...

Stonehenge
Stonehenge is a prehistoric Megalith, megalithic structure on Salisbury Plain in Wiltshire, England, west of Amesbury. It consists of an outer ring of vertical sarsen standing stones, each around high, wide, and weighing around 25 tons, topped by connecting horizontal lintel stones, held in place with mortise and tenon joints, a feature unique among contemporary monuments. Inside is a ring of smaller bluestones. Inside these are free-standing trilithons, two bulkier vertical sarsens joined by one lintel. The whole monument, now ruinous, is aligned towards the sunrise on the summer solstice and sunset on the winter solstice. The stones are set within Earthwork (archaeology), earthworks in the middle of the densest complex of Neolithic British Isles, Neolithic and Bronze Age Britain, Bronze Age monuments in England, including several hundred ''tumuli'' (burial mounds). Stonehenge was constructed in several phases beginning about 3100 BC and continuing until about 1600 B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Niya Ruins
The Niya ruins (), is an archaeological site located about north of modern Niya Town on the southern edge of the Tarim Basin in modern-day Xinjiang, China. The ancient site was known in its native language as Caḍ́ota, and in Chinese during the Han dynasty as Jingjue (, Old Chinese ''tseng-dzot'', similar to ''Caḍ́ota''). Numerous ancient archaeological artifacts have been uncovered at the site. Niya was once a major commercial center on an oasis on the southern branch of the Silk Road in the southern Taklamakan Desert. During ancient times camel caravans would cut through, carrying goods from China to Central Asia. History In ''Hanshu'', an independent oasis state called Jingjue, generally thought to be Niya, is mentioned: Niya became part of Loulan Kingdom by the third century. Towards the end of the fourth century it was under Chinese suzerainty. Later it was conquered by Tibet. Excavations In 1900, Aurel Stein set out on an expedition to western China and the Tak ...

Silk Road
The Silk Road was a network of Asian trade routes active from the second century BCE until the mid-15th century. Spanning over , it played a central role in facilitating economic, cultural, political, and religious interactions between the Eastern world, Eastern and Western worlds. The name "Silk Road" was coined in the late 19th century, but some 20th- and 21st-century historians instead prefer the term Silk Routes, on the grounds that it more accurately describes the intricate web of land and sea routes connecting Central Asia, Central, East Asia, East, South Asia, South, Southeast Asia, Southeast, and West Asia as well as East Africa and Southern Europe. The Silk Road derives its name from the highly lucrative trade of silk textiles that were History of Silk, primarily produced in China. The network began with the expansion of the Han dynasty (202 BCE220 CE) into Central Asia around 114 BCE, through the missions and explorations of the Chinese imperial env ...
