Armley Asbestos Disaster
The Armley asbestos disaster is an ongoing health issue originating in Armley, a suburb of Leeds, West Yorkshire, England. Described by Dr. Geoffrey Tweedale as a "social disaster", it involved the contamination with asbestos dust of an area consisting of around 1,000 houses in the Armley Lodge area of the city. The contamination was the result of the activities of a local asbestos factory, part of the Turner & Newall (T&N) group (often referred to by the name of its founders, J. W. Roberts Ltd.) and occurred between the end of the 19th century and 1959 when the factory eventually closed. At its peak the factory had 250 employees. At least 300 former employees are believed to have died from asbestos-related illnesses, and a number of cancer deaths in the Armley area were traced to the factory in 1988 as a result of an investigation by the ''Yorkshire Evening Post''. The estate was found to have the highest incidence in the country of mesothelioma. As the interval between exposure a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armley Suburbs
Armley is a district in the west of Leeds, West Yorkshire, England. It starts less than from Leeds city centre. Like much of Leeds, Armley grew in the Industrial Revolution and had several textile mill, mills, one of which houses now the Leeds Industrial Museum at Armley Mills. Armley is predominantly and historically a largely working class area of the city, still retains many smaller industrial businesses, and has many rows of Back-to-back house, back-to-back terraced houses. It sits in the Armley (ward), Armley ward of Leeds City Council and Leeds West (UK Parliament constituency), Leeds West parliamentary constituency. In 2022, statistics released by West Yorkshire Police revealed Armley and New Wortley had the second highest crime rate in Leeds after Leeds city centre. Etymology First attested in the Domesday Book of 1086 as ''Ermelai'', the name ''Armley'' comes from Old English. The second element is from Old English ''lēah'' ('open space in a wood').

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Loading Dock
A loading dock or loading bay is an area of a building where goods vehicles (usually road or rail) are loaded and unloaded. They are commonly found on commercial and industrial buildings, and warehouses in particular. Loading docks may be exterior, flush with the building envelope, or fully enclosed. They are part of a facility's service or utility infrastructure, typically providing direct access to staging areas, storage rooms, and freight elevators. Basics In order to facilitate material handling, loading docks may be equipped with the following: * Bumpers – protect the dock from truck damage, may also be used as a guide by the truck driver when backing up. * Dock leveler – a height-adjustable platform used as a bridge between dock and truck, can be operated via mechanical (spring), hydraulic, or air powered systems. * Dock lift – serves the same function as a leveler, but operates similar to a scissor lift to allow for greater height adjustments. * Dock seals or dock ...

Hopscotch
Hopscotch is a popular playground game in which players toss a small object, called a lagger, into numbered triangles or a pattern of rectangles outlined on the ground and then hop or jump through the spaces and retrieve the object. It is a children's game that can be played with several players or alone. Hopscotch is a physical and cognitive workout. Court and rules The court To play hopscotch, a court is first laid out on the ground. Depending on the available surface, the court is either scratched out in the dirt or drawn with chalk on pavement. Courts may be permanently marked where playgrounds are commonly paved, as in elementary schools. Designs vary, but the court is usually composed of a series of linear squares interspersed with blocks of two lateral squares. Traditionally the court ends with a "safe" or "home" base in which the player may turn before completing the reverse trip. The home base may be a square, a rectangle, or a semicircle. The squares are th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Playground
A playground, playpark, or play area is a place designed to provide an environment for children that facilitates play, typically outdoors. While a playground is usually designed for children, some are designed for other age groups, or people with disabilities. A playground might exclude children below (or above) a certain age. Modern playgrounds often have recreational equipment such as the seesaw, merry-go-round, swingset, slide, jungle gym, chin-up bars, sandbox, spring rider, trapeze rings, playhouses, and mazes, many of which help children develop physical coordination, strength, and flexibility, as well as providing recreation and enjoyment and supporting social and emotional development. Common in modern playgrounds are ''play structures'' that link many different pieces of equipment. Playgrounds often also have facilities for playing informal games of adult sports, such as a baseball diamond, a skating arena, a basketball court, or a tether ball. Public playgro ...

Hansard
''Hansard'' is the traditional name of the transcripts of parliamentary debates in Britain and many Commonwealth countries. It is named after Thomas Curson Hansard (1776–1833), a London printer and publisher, who was the first official printer to the Parliament at Westminster. Origins Though the history of the ''Hansard'' began in the British parliament, each of Britain's colonies developed a separate and distinctive history. Before 1771, the British Parliament had long been a highly secretive body. The official record of the actions of the House was publicly available but there was no record of the debates. The publication of remarks made in the House became a breach of parliamentary privilege, punishable by the two Houses of Parliament. As the populace became interested in parliamentary debates, more independent newspapers began publishing unofficial accounts of them. The many penalties implemented by the government, including fines, dismissal, imprisonment, and investigati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ventilation (architecture)
Ventilation is the intentional introduction of outdoor air into a space. Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used to control indoor temperature, humidity, and air motion to benefit thermal comfort, satisfaction with other aspects of indoor environment, or other objectives. The intentional introduction of outdoor air is usually categorized as either mechanical ventilation, natural ventilation, or mixed-mode ventilation (hybrid ventilation). * Mechanical ventilation is the intentional fan driven flow of outdoor air into a building. Mechanical ventilation systems may include supply fans (which push outdoor air into a building), exhaust fans (which draw air out of building and thereby cause equal ventilation flow into a building), or a combination of both. Mechanical ventilation is often provided by equipment that is also used to heat and cool a space. * Natural ventilation is the intentional passive fl ...

The Guardian
''The Guardian'' is a British daily newspaper. It was founded in 1821 as ''The Manchester Guardian'', and changed its name in 1959. Along with its sister papers ''The Observer'' and ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. Since 2018, the paper's main news ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Underground
The London Underground (also known simply as the Underground or by its nickname the Tube) is a rapid transit system serving Greater London and some parts of the adjacent ceremonial counties of England, counties of Buckinghamshire, Essex and Hertfordshire in England. The Underground has its origins in the Metropolitan Railway, the world's first underground passenger railway. Opened on 10 January 1863, it is now part of the Circle line (London Underground), Circle, District line, District, Hammersmith & City line, Hammersmith & City and Metropolitan lines. The first line to operate underground electric locomotive, electric traction trains, the City & South London Railway in 1890, is now part of the Northern line. The network has expanded to 11 lines, and in 2020/21 was used for 296 million passenger journeys, making it List of metro systems, one of the world's busiest metro systems. The 11 lines collectively handle up to 5 million passenger journeys a day and serve 272 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fireproofing
Fireproofing is rendering something (structures, materials, etc.) resistant to fire, or incombustible; or material for use in making anything fire-proof. It is a passive fire protection measure. "Fireproof" or "fireproofing" can be used as a noun, verb or adjective; it may be hyphenated ("fire-proof"). Applying a certification listed fireproofing system to certain structures allows them to have a fire-resistance rating. The term "fireproofing" may be used in conjunction with standards, as reflected in common North American construction specifications. An item classed as fireproof is resistant in specified circumstances, and may burn or be rendered inoperable by fire exceeding the intensity or duration that it is designed to withstand. Markets * Commercial construction * Residential construction * Industrial construction * Marine (ships) * Offshore construction * Aerodynamics * Tunnel concrete walls and ceilings or linings * Under- and above-ground mining operations Applicati ...

Soundproofing
Soundproofing is any means of impeding sound propagation. There are several basic approaches to reducing sound: increasing the distance between source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using active antinoise sound generators. Acoustic quieting and noise control can be used to limit unwanted noise. Soundproofing can reduce the transmission of unwanted direct sound waves from the source to an involuntary listener through the use of distance and intervening objects in the sound path (see sound transmission class and sound reduction index). Soundproofing can suppress unwanted indirect sound waves such as reflections that cause echoes and resonances that cause reverberation. Absorption Sound-absorbing material controls reverberant sound pressure levels within a cavity, enclosure or room. Synthetic absorption materials are porous, referring to open ce ...

Portland Cement
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone. It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2 to 3 percent of gypsum. Several types of portland cement are available. The most common, called ordinary portland cement (OPC), is grey, but white Portland cement is also available. Its name is derived from its resemblance to Portland stone which was quarried on the Isle of Portland in Dorset, England. It was named by Joseph Aspdin who obtained a patent for it in 1824. His son William Aspdin is regarded as the inventor of "modern" portland cement due to his developments in the 1840s. The low cost and widespread availability of the limestone, shales ...
