Wimbledon, London
Wimbledon () is a district and town of Southwest London, England, southwest of the centre of London at Charing Cross; it is the main commercial centre of the London Borough of Merton. Wimbledon had a population of 68,187 in 2011 which includes the electoral wards of Abbey, Dundonald, Hillside, Trinity, Village, Raynes Park and Wimbledon Park. It is home to the Wimbledon Championships and New Wimbledon Theatre, and contains Wimbledon Common, one of the largest areas of common land in London. The residential and retail area is split into two sections known as the "village" and the "town", with the High Street being the rebuilding of the original medieval village, and the "town" having first developed gradually after the building of the railway station in 1838. Wimbledon has been inhabited since at least the Iron Age when the hill fort on Wimbledon Common is thought to have been constructed. In 1086 when the Domesday Book was compiled, Wimbledon was part of the manor of Mortla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Master Of Arts
A Master of Arts ( la, Magister Artium or ''Artium Magister''; abbreviated MA, M.A., AM, or A.M.) is the holder of a master's degree awarded by universities in many countries. The degree is usually contrasted with that of Master of Science. Those admitted to the degree have typically studied subjects within the scope of the humanities and social sciences, such as history, literature, languages, linguistics, public administration, political science, communication studies, law or diplomacy; however, different universities have different conventions and may also offer the degree for fields typically considered within the natural sciences and mathematics. The degree can be conferred in respect of completing courses and passing examinations, research, or a combination of the two. The degree of Master of Arts traces its origins to the teaching license or of the University of Paris, designed to produce "masters" who were graduate teachers of their subjects.

Thixotropy
Thixotropy is a time-dependent shear thinning property. Certain gels or fluids that are thick or viscous under static conditions will flow (become thinner, less viscous) over time when shaken, agitated, shear-stressed, or otherwise stressed ( time-dependent viscosity). They then take a fixed time to return to a more viscous state. Some non-Newtonian pseudoplastic fluids show a time-dependent change in viscosity; the longer the fluid undergoes shear stress, the lower its viscosity. A thixotropic fluid is a fluid which takes a finite time to attain equilibrium viscosity when introduced to a steep change in shear rate. Some thixotropic fluids return to a gel state almost instantly, such as ketchup, and are called pseudoplastic fluids. Others such as yogurt take much longer and can become nearly solid. Many gels and colloids are thixotropic materials, exhibiting a stable form at rest but becoming fluid when agitated. Thixotropy arises because particles or structured solutes re ...

Bentonite
Bentonite () is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca-montmorillonite. Na-montmorillonite has a considerably greater swelling capacity than Ca-montmorillonite. Bentonite usually forms from the weathering of volcanic ash in seawater, or by hydrothermal circulation through the porosity of volcanic ash beds, which converts ( devitrification) the volcanic glass (obsidian, rhyolite, dacite) present in the ash into clay minerals. In the mineral alteration process, a large fraction (up to 40-50 wt.%) of amorphous silica is dissolved and leached away, leaving the bentonite deposit in place. Bentonite beds are white or pale blue or green (traces of reduced ) in fresh exposures, turning to a cream color and then yellow, red, or brown (traces of oxidized ) as the exposure is weathered further. As a swelling clay, bentonite has the ability to absorb large quantities of water, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnel Boring Machine
A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They may also be used for microtunneling. They can be designed to bore through hard rock, wet or dry soil, or sand. Tunnel diameters can range from (micro-TBMs) to to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drilling rather than TBMs. TBMs can be designed to excavate non-circular tunnels, including u-shaped, horseshoe, square or rectangular tunnels. Tunnel boring machines are used as an alternative to drilling and blasting (D&B) methods in rock and conventional "hand mining" in soil. TBMs have the advantages of limiting the disturbance to the surrounding ground and producing a smooth tunnel wall. This significantly reduces the cost of lining the tunnel, and makes them suitable to use in urban areas. The major disadva ...

British Tunnelling Society
The British Tunnelling Society (BTS) is a professional association established in London, UK, in 1971 by tunnelling professionals, led by Sir Harold Harding. The BTS is a learned society of the Institution of Civil Engineers, its mission being to provide a forum for meetings and discussion on tunnel-related matters. The BTS took part in the founding of the International Tunneling and Underground Space Association (ITA-AITES) in 1974 and represents the UK on its General Assembly. In 2016, the BTS had 800 members making it one of the largest. The current chairman of the BTS, Rod Young, assumed the position in May 2022.

Commander Of The Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service. It was established on 4 June 1917 by King George V and comprises five classes across both civil and military divisions, the most senior two of which make the recipient either a knight if male or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order. Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceased recommendations for appointments to the Order of the British Empire when the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Channel Tunnel
The Channel Tunnel (french: Tunnel sous la Manche), also known as the Chunnel, is a railway tunnel that connects Folkestone ( Kent, England, UK) with Coquelles (Hauts-de-France, France) beneath the English Channel at the Strait of Dover. It is the only fixed link between the island of Great Britain and the European mainland. At its lowest point, it is deep below the sea bed and below sea level. At , it has the longest underwater section of any tunnel in the world, and is the third longest railway tunnel in the world. The speed limit for trains through the tunnel is . The tunnel is owned and operated by the company Getlink, formerly "Groupe Eurotunnel". The tunnel carries high-speed Eurostar passenger trains, the Eurotunnel Shuttle for road vehicles and international freight trains. It connects end-to-end with the high-speed railway lines of the LGV Nord in France and High Speed 1 in England. In 2017, through rail services carried 10.3 million passengers and 1.2 ...

Victoria Line
The Victoria line is a London Underground line that runs between in south London and in the north-east, via the West End. It is printed in light blue on the Tube map and is one of the only two lines on the network to run completely underground, the other being the Waterloo & City line. The line was constructed in the 1960s and was the first entirely new Underground line in London for 50 years. It was designed to reduce congestion on other lines, particularly the Piccadilly line and the branch of the Northern line. The first section, from Walthamstow Central to , opened in September 1968 and an extension to followed in December. The line was completed to Victoria station in March 1969 and was opened by Queen Elizabeth II who rode a train from Green Park to Victoria. The southern extension to Brixton opened in 1971, and Pimlico station was added in 1972. The Victoria line is operated using automatic train operation, but all trains have drivers.
