Taunton Sleeping Car Fire
In the early hours of 6 July 1978, a fire broke out in a sleeping car train near Taunton, Somerset, England. 12 people were killed and 15 were injured. The fire was caused by an electric heater that had been obstructed by sacks of dirty bed linen, causing it to overheat. Most deaths were due to smoke inhalation. In response to the incident, British Rail adopted various fire safety measures on the newly introduced Mark 3 passenger carriages. Background The fire started in a British Railways Mark 1 sleeping car (no. W2437) which had been built in 1960, at which time trains in the UK were mostly hauled by steam locomotives, which provided steam for heating passenger accommodation. Diesel locomotives of the period were fitted with boilers so that they could be used with existing coaches. However, with steam locomotives gone by the 1970s, and with boilers proving unreliable and expensive to maintain, the decision was made to change to electric train heating (ETH). W2437 was conve ...

British Railways Mark 1 Sleeping Car
British Railways Mark 1 is the family designation for the first standardised designs of railway carriages built by British Railways (BR) from 1951 until 1974, now used only for charter services on the main lines or on preserved railways. Following nationalisation in 1948, BR had continued to build carriages to the designs of the "Big Four" companies (the Great Western, Southern, London, Midland and Scottish and London and North Eastern railways), and the Mark 1 was intended to be the standard carriage design for use across all lines, incorporating the best features of each of the former companies' designs. It was also designed to be much stronger than previous designs, to provide better protection for passengers in the event of a collision or derailment. The Mark 1 coaches were built in two distinct tranches: the early vehicles (1951–1960) and the 'Commonwealth' stock (named from the type of bogie used) from 1961 onwards. Construction The design was used for hauled passen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1, ...

Pneumonia
Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. The severity of the condition is variable. Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis. The disease may be classified by where it was acquired, such as community- or hospital-acquired or healthcare-associated pneumonia. Risk factors for pneumonia include cystic fibrosis, chronic obstructive pulmonary disease (COPD), sickle cell disease, asthma, diabetes, heart failure, a history of smoking, a poor ability to cough (such as following a stroke), and a weak immune system.

Musgrove Park Hospital
Musgrove Park Hospital is a large NHS hospital located in Taunton, Somerset, England, run by Somerset NHS Foundation Trust. Originally a US Army General Hospital during the Second World War, it became an NHS hospital in 1951. History The 67th General Hospital was authorised on 3 March 1941, during the Second World War, and activated 1 September 1942 as an American Army Hospital and occupied by the U.S. Army Medical Corps. After the war, it continued in use as a Ministry of Pensions Hospital and only became a General Hospital within the National Health Service in 1951. Early royal visits included those by Queen Elizabeth The Queen Mother in 1959 and by Princess Anne in 1970, when she opened the Intensive Therapy Unit. Following an operation on his foot in 1977, Somerset cricketer Ian Botham mistakenly walked into a children's ward at Musgrove Park. He gives this as his inspiration for raising millions of pounds for leukaemia charities. During the great snow of February 1978, th ...

Heat
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is also often used to refer to the thermal energy contained in a system as a component of its internal energy and that is reflected in the temperature of the system. For both uses of the term, heat is a form of energy. An example of formal vs. informal usage may be obtained from the right-hand photo, in which the metal bar is "conducting heat" from its hot end to its cold end, but if the metal bar is considered a thermodynamic system, then the energy flowing within the metal bar is called internal energy, not heat. The hot metal bar is also transferring heat to its surroundings, a correct statement for both the strict and loose meanings of ''heat''. Another example of informal usage is the term '' heat content'', used despite the fact that p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smoke
Smoke is a suspension of airborne particulates and gases emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass. It is commonly an unwanted by-product of fires (including stoves, candles, internal combustion engines, oil lamps, and fireplaces), but may also be used for pest control ( fumigation), communication ( smoke signals), defensive and offensive capabilities in the military (smoke screen), cooking, or smoking (tobacco, cannabis, etc.). It is used in rituals where incense, sage, or resin is burned to produce a smell for spiritual or magical purposes. It can also be a flavoring agent and preservative. Smoke inhalation is the primary cause of death in victims of indoor fires. The smoke kills by a combination of thermal damage, poisoning and pulmonary irritation caused by carbon monoxide, hydrogen cyanide and other combustion products. Smoke is an aerosol (or mist) of solid particl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Monoxide Poisoning
Carbon monoxide poisoning typically occurs from breathing in carbon monoxide (CO) at excessive levels. Symptoms are often described as "flu-like" and commonly include headache, dizziness, weakness, vomiting, chest pain, and confusion. Large exposures can result in loss of consciousness, arrhythmias, seizures, or death. The classically described "cherry red skin" rarely occurs. Long-term complications may include chronic fatigue, trouble with memory, and movement problems. CO is a colorless and odorless gas which is initially non-irritating. It is produced during incomplete burning of organic matter. This can occur from motor vehicles, heaters, or cooking equipment that run on carbon-based fuels. Carbon monoxide primarily causes adverse effects by combining with hemoglobin to form carboxyhemoglobin (HbCO) preventing the blood from carrying oxygen and expelling carbon dioxide as carbaminohemoglobin. Additionally, many other hemoproteins such as myoglobin, Cytochrome P450, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communication Cord
On trains, the expression emergency brake has several meanings: * The ''maximum'' brake force available to the engine driver from the conventional braking system, usually operated by taking the brake handle to its furthest position, through a gate mechanism, or by pushing a separate plunger in the cab. * A completely separate mechanism from the conventional braking system, designed to stop the train as quickly as possible. * A handle or plunger which may be applied by a passenger in an emergency situation, either stopping the train directly or sending an alarm to the driver so that they can stop the train. The emergency brake applies considerably more braking force than the standard full-service brake. The engine driver or motorman will only use the emergency brake as a last resort, since it may cause damage; even with modern wheel slide protection, a train may develop wheel-flats, and the rails themselves can suffer profile damage. Possible consequences of operation Putting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taunton
Taunton () is the county town of Somerset, England, with a 2011 population of 69,570. Its thousand-year history includes a 10th-century monastic foundation, Taunton Castle, which later became a priory. The Normans built a castle owned by the Bishops of Winchester. Parts of the inner ward house were turned into the Museum of Somerset and Somerset Military Museum. For the Second Cornish uprising of 1497, Perkin Warbeck brought an army of 6,000; most surrendered to Henry VII on 4 October 1497. On 20 June 1685 the Duke of Monmouth crowned himself King of England here in a rebellion, defeated at the Battle of Sedgemoor. Judge Jeffreys led the Bloody Assizes in the Castle's Great Hall. The Grand Western Canal reached Taunton in 1839 and the Bristol and Exeter Railway in 1842. Today it hosts Musgrove Park Hospital, Somerset County Cricket Club, is the base of 40 Commando, Royal Marines, and is home to the United Kingdom Hydrographic Office on Admiralty Way.

Signal Box
In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The ''IEEE Transactions on Signal Processing'' includes audio, video, speech, image, sonar, and radar as examples of signal. A signal may also be defined as observable change in a quantity over space or time (a time series), even if it does not carry information. In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signaling occurs in all organisms even at cellular levels, with cell signaling. Signaling theory, in evolutionary biology, proposes that a substantial driver for evolution is the ability of animals to communicate with each other by developing ways of signaling. In human engineering, signals are typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Monoxide
Carbon monoxide (chemical formula CO) is a colorless, poisonous, odorless, tasteless, flammable gas that is slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest molecule of the oxocarbon family. In coordination complexes the carbon monoxide ligand is called carbonyl. It is a key ingredient in many processes in industrial chemistry. The most common source of carbon monoxide is the partial combustion of carbon-containing compounds, when insufficient oxygen or heat is present to produce carbon dioxide. There are also numerous environmental and biological sources that generate and emit a significant amount of carbon monoxide. It is important in the production of many compounds, including drugs, fragrances, and fuels. Upon emission into the atmosphere, carbon monoxide affects several processes that contribute to climate change. Carbon monoxide has important biological roles across phylogenetic ...
