Prefabricated Structure
Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located. The term is used to distinguish this process from the more conventional construction practice of transporting the basic materials to the construction site where all assembly is carried out. The term ''prefabrication'' also applies to the manufacturing of things other than structures at a fixed site. It is frequently used when fabrication of a section of a machine or any movable structure is shifted from the main manufacturing site to another location, and the section is supplied assembled and ready to fit. It is not generally used to refer to electrical or electronic components of a machine, or mechanical parts such as pumps, gearboxes and compressors which are usually supplied as separate items, but to sections of the body of the machine which in the ...

Structure
A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms, minerals and chemicals. Abstract structures include data structures in computer science and musical form. Types of structure include a hierarchy (a cascade of one-to-many relationships), a network featuring many-to-many links, or a lattice featuring connections between components that are neighbors in space. Load-bearing Buildings, aircraft, skeletons, anthills, beaver dams, bridges and salt domes are all examples of load-bearing structures. The results of construction are divided into buildings and non-building structures, and make up the infrastructure of a human society. Built structures are broadly divided by their varying design approaches and standards, into categories including building structures, arch ...

Ship
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and ...

Lisbon Earthquake Of 1755
The 1755 Lisbon earthquake, also known as the Great Lisbon earthquake, impacted Portugal, the Iberian Peninsula, and Northwest Africa on the morning of Saturday, 1 November, Feast of All Saints, at around 09:40 local time. In combination with subsequent fires and a tsunami, the earthquake almost completely destroyed Lisbon and adjoining areas. Seismologists estimate the Lisbon earthquake had a magnitude of 7.7 or greater on the moment magnitude scale, with its epicenter in the Atlantic Ocean about west-southwest of Cape St. Vincent and about southwest of Lisbon. Chronologically, it was the third known large scale earthquake to hit the city (following those of 1321 and 1531). Estimates place the death toll in Lisbon at between 12,000 and 50,000 people, making it one of the deadliest earthquakes in history. The earthquake accentuated political tensions in Portugal and profoundly disrupted the Portuguese Empire. The event was widely discussed and dwelt upon by European E ...

Kingdom Of Polonnaruwa
The Kingdom of Polonnaruwa ( si, පොළොන්නරුව රාජධානිය, Polonnaruwa Rājādhaniya) was the Sinhalese kingdom that expanded across the island of Sri Lanka and several overseas territories, from 1070 until 1232. The kingdom started expanding its overseas authority during the reign of Parakramabahu the Great. It had a stronghold in South India since its involvement in a civil war in the Pandya country. During this war, Pandya Nadu was seized as a province administered by the military of Polonnaruwa. The tributaries of the Chola empire, Tondi and Pasi, also came under its military rule. Rameshwaram was under Sinhalese rule until 1182. Its currency ''Kahapana'' was struck in these provinces. During the occupation of South India, construction works were undertaken. Despite being a kingdom, it had been under the control of its royal military, which captured power twice and remained dominant in politics. Other militaries also had captured power in t ...

Anuradhapura Kingdom
The Anuradhapura Kingdom (Sinhala language, Sinhala: , translit: Anurādhapura Rājadhāniya, Tamil language, Tamil: ), named for Anuradhapura, its capital city, was the first established monarchy, kingdom in ancient Sri Lanka related to the Sinhalese people. Founded by King Pandukabhaya in 437 BC, the kingdom's authority extended throughout the country, although several independent areas emerged from time to time which expanded towards the end of the kingdom. Nonetheless, the king of Anuradhapura was seen as the supreme ruler of the entire island throughout the Anuradhapura period. Buddhism played a major role in the Anuradhapura period, influencing its culture, laws, and methods of governance.Buddhism was such an important factor in this period that , p.196 asserts, "The island of Lanka belonged to the Buddha himself; it was like a treasury filled with the Three Jewels, three gems". The society and the culture were revolutionized when the faith was introduced during the rei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sri Lanka
Sri Lanka (, ; si, ශ්රී ලංකා, Śrī Laṅkā, translit-std=ISO (); ta, இலங்கை, Ilaṅkai, translit-std=ISO ()), formerly known as Ceylon and officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, and southeast of the Arabian Sea; it is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait.

Sinhalese People
Sinhalese people ( si, සිංහල ජනතාව, Sinhala Janathāva) are an Indo-Aryan ethnolinguistic group native to the island of Sri Lanka. They were historically known as Hela people ( si, හෙළ). They constitute about 75% of the Sri Lankan population and number more than 16.2 million. The Sinhalese identity is based on language, cultural heritage and nationality. The Sinhalese people speak Sinhala, an insular Indo-Aryan language, and are predominantly Theravada Buddhists, although a minority of Sinhalese follow branches of Christianity and other religions. Since 1815, they were broadly divided into two respective groups: The 'Up-country Sinhalese' in the central mountainous regions, and the 'Low-country Sinhalese' in the coastal regions; although both groups speak the same language, they are distinguished as they observe different cultural customs. According to the Mahavamsa and the Dipavamsa, a third–fifth century treatise written in Pali by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sweet Track
The Sweet Track is an ancient trackway, or causeway, in the Somerset Levels, England, named after its finder, Ray Sweet. It was built in 3807 BC (determined using dendrochronology) and is the second-oldest timber trackway discovered in the British Isles, dating to the Neolithic. It is now known that the Sweet Track was predominantly built along the course of an earlier structure, the Post Track. The track extended across the now largely drained marsh between what was then an island at Westhay and a ridge of high ground at Shapwick, a distance close to or around . The track is one of a network that once crossed the Somerset Levels. Various artifacts and prehistoric finds, including a jadeitite ceremonial axe head, have been found in the peat bogs along its length. Construction was of crossed wooden poles, driven into the waterlogged soil to support a walkway that consisted mainly of planks of oak, laid end-to-end. The track was used for a period of only around ten years a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", whic ...

Assembly Line
An assembly line is a manufacturing process (often called a ''progressive assembly'') in which parts (usually interchangeable parts) are added as the semi-finished assembly moves from workstation to workstation where the parts are added in sequence until the final assembly is produced. By mechanically moving the parts to the assembly work and moving the semi-finished assembly from work station to work station, a finished product can be assembled faster and with less labor than by having workers carry parts to a stationary piece for assembly. Assembly lines are common methods of assembling complex items such as automobiles and other transportation equipment, household appliances and electronic goods. Workers in charge of the works of assembly line are called assemblers. Concepts Assembly lines are designed for the sequential organization of workers, tools or machines, and parts. The motion of workers is minimized to the extent possible. All parts or assemblies are handled e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
