Luftwaffe
The ''Luftwaffe'' () was the aerial-warfare branch of the German ''Wehrmacht'' before and during World War II. Germany's military air arms during World War I, the ''Luftstreitkräfte'' of the Imperial Army and the '' Marine-Fliegerabteilung'' of the Imperial Navy, had been disbanded in May 1920 in accordance with the terms of the 1919 Treaty of Versailles which banned Germany from having any air force. During the interwar period, German pilots were trained secretly in violation of the treaty at Lipetsk Air Base in the Soviet Union. With the rise of the Nazi Party and the repudiation of the Versailles Treaty, the ''Luftwaffe''s existence was publicly acknowledged on 26 February 1935, just over two weeks before open defiance of the Versailles Treaty through German rearmament and conscription would be announced on 16 March. The Condor Legion, a ''Luftwaffe'' detachment sent to aid Nationalist forces in the Spanish Civil War, provided the force with a valuable testing grou ...

Coventry Blitz
The Coventry Blitz ( blitz: from the German word ''Blitzkrieg'' meaning "lightning war" ) or Coventration of the city was a series of bombing raids that took place on the British city of Coventry. The city was bombed many times during the Second World War by the German Air Force (''Luftwaffe''). The most devastating of these attacks occurred on the evening of 14 November 1940 and continued into the morning of 15 November. Background At the start of the Second World War, Coventry was an industrial city of around 238,000 people which, like much of the industrial West Midlands, contained metal and wood-working industries. In Coventry's case, these included cars, bicycles, aeroplane engines and, since 1900, munitions factories. In the words of the historian Frederick Taylor, "Coventry was therefore, in terms of what little law existed on the subject, a legitimate target for aerial bombing". During the First World War, the advanced state of the mechanical tooling in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Midlands
The Midlands (also referred to as Central England) are a part of England that broadly correspond to the Kingdom of Mercia of the Early Middle Ages, bordered by Wales, Northern England and Southern England. The Midlands were important in the Industrial Revolution of the 18th and 19th centuries. They are split into the West Midlands and East Midlands. The region's biggest city, Birmingham often considered the social, cultural, financial and commercial centre of the Midlands, is the second-largest city and metropolitan area in the United Kingdom. Symbolism A saltire (diagonal cross) may have been used as a symbol of Mercia as early as the reign of Offa. By the 13th century, the saltire had become the attributed arms of the Kingdom of Mercia. The arms are blazoned ''Azure, a saltire Or'', meaning a gold (or yellow) saltire on a blue field. The saltire is used as both a flag and a coat of arms. As a flag, it is flown from Tamworth Castle, the ancient seat of the Mercian Kings, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspirin
Aspirin, also known as acetylsalicylic acid (ASA), is a nonsteroidal anti-inflammatory drug (NSAID) used to reduce pain, fever, and/or inflammation, and as an antithrombotic. Specific inflammatory conditions which aspirin is used to treat include Kawasaki disease, pericarditis, and rheumatic fever. Aspirin is also used long-term to help prevent further heart attacks, ischaemic strokes, and blood clots in people at high risk. For pain or fever, effects typically begin within 30 minutes. Aspirin works similarly to other NSAIDs but also suppresses the normal functioning of platelets. One common adverse effect is an upset stomach. More significant side effects include stomach ulcers, stomach bleeding, and worsening asthma. Bleeding risk is greater among those who are older, drink alcohol, take other NSAIDs, or are on other blood thinners. Aspirin is not recommended in the last part of pregnancy. It is not generally recommended in children with infections because of the risk of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diathermy
Diathermy is electrically induced heat or the use of high-frequency electromagnetic currents as a form of physical therapy and in surgical procedures. The earliest observations on the reactions of high-frequency electromagnetic currents upon the human organism were made by Jacques Arsene d'Arsonval. The field was pioneered in 1907 by German physician Karl Franz Nagelschmidt, who coined the term ''diathermy'' from the Greek words ''dia'' and θέρμη ''therma'', literally meaning "heating through" (adj., diather´mal, diather´mic). Diathermy is commonly used for muscle relaxation, and to induce deep heating in tissue for therapeutic purposes in medicine. It is used in physical therapy to deliver moderate heat directly to pathologic lesions in the deeper tissues of the body. Diathermy is produced by three techniques: ultrasound (''ultrasonic diathermy''), short-wave radio frequencies in the range 1–100 MHz (''shortwave diathermy'') or microwaves typically in the 915&nb ...

RAF Bentley Priory
RAF Bentley Priory was a non-flying Royal Air Force station near Stanmore in the London Borough of Harrow. It was the headquarters of Fighter Command in the Battle of Britain and throughout the Second World War. During the war, two enemy bombs destroyed a wooden hut near the married quarters, a blast from a V-1 flying bomb broke a few windows, the windows in the Officers' Mess were shattered by a V-2 rocket, and a Vickers Wellington crashed outside the Sergeants' Mess. The Royal Air Force station closed its operations on 30 May 2008, with all units relocating to new accommodation at RAF Northolt, a few miles away. The station incorporated Bentley Priory, which was originally built in 1766. The house was significantly extended in 1788, by Sir John Soane, for John Hamilton, 1st Marquess of Abercorn. It was the final home of the dowager Queen Adelaide, queen consort of William IV, before her death there in 1849. Afterwards the building was used as a hotel and girls' school b ...

RAF Fighter Command
RAF Fighter Command was one of the commands of the Royal Air Force. It was formed in 1936 to allow more specialised control of fighter aircraft. It served throughout the Second World War. It earned near-immortal fame during the Battle of Britain in 1940, when the Few held off the Luftwaffe attack on Britain. The Command continued until 17 November 1943, when it was disbanded and the RAF fighter force was split into two categories; defence and attack. The defensive force became Air Defence of Great Britain (ADGB) and the offensive force became the RAF Second Tactical Air Force. Air Defence of Great Britain was renamed back to Fighter Command in October 1944 and continued to provide defensive patrols around Great Britain. It was disbanded for the second time in 1968, when it was subsumed into the new Strike Command. Origins On 20 May 1926, the forerunner of Fighter Command was established as a group within Inland Area. On 1 June 1926, Fighting Area was transferred to the ...

Air Ministry
The Air Ministry was a department of the Government of the United Kingdom with the responsibility of managing the affairs of the Royal Air Force, that existed from 1918 to 1964. It was under the political authority of the Secretary of State for Air. Organisations before the Air Ministry The Air Committee On 13 April 1912, less than two weeks after the creation of the Royal Flying Corps (which initially consisted of both a naval and a military wing), an Air Committee was established to act as an intermediary between the Admiralty and the War Office in matters relating to aviation. The new Air Committee was composed of representatives of the two war ministries, and although it could make recommendations, it lacked executive authority. The recommendations of the Air Committee had to be ratified by the Admiralty Board and the Imperial General Staff and, in consequence, the Committee was not particularly effective. The increasing separation of army and naval aviation from 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Blitz
The Blitz was a German bombing campaign against the United Kingdom in 1940 and 1941, during the Second World War. The term was first used by the British press and originated from the term , the German word meaning 'lightning war'. The Germans conducted mass air attacks against industrial targets, towns, and cities, beginning with raids on London towards the end of the Battle of Britain in 1940 (a battle for daylight air superiority between the Luftwaffe and the Royal Air Force over the United Kingdom). By September 1940, the Luftwaffe had lost the Battle of Britain and the German air fleets () were ordered to attack London, to draw RAF Fighter Command into a battle of annihilation.Price 1990, p. 12. Adolf Hitler and Reichsmarschall Hermann Göring, commander-in-chief of the Luftwaffe, ordered the new policy on 6 September 1940. From 7 September 1940, London was systematically bombed by the Luftwaffe for 56 of the following 57 days and nights. Most notable was a large dayli ...

Telecommunications Research Establishment
The Telecommunications Research Establishment (TRE) was the main United Kingdom research and development organization for radio navigation, radar, infra-red detection for heat seeking missiles, and related work for the Royal Air Force (RAF) during World War II and the years that followed. It was regarded as "the most brilliant and successful of the English wartime research establishments" under "Rowe, who saw more of the English scientific choices between 1935 and 1945 than any single man." The name was changed to Radar Research Establishment in 1953, and again to the Royal Radar Establishment in 1957. This article covers the precursor organizations and the Telecommunications Research Establishment up to the time of the name change. The later work at the site is described in the separate article about RRE. History TRE is best known for work on defensive and offensive radar. TRE also made substantial contributions to radio-navigation and to jamming enemy radio-navigation. Ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
