RRE
The Royal Radar Establishment was a research centre in Malvern, Worcestershire in the United Kingdom. It was formed in 1953 as the Radar Research Establishment by the merger of the Air Ministry's Telecommunications Research Establishment (TRE) and the British Army's Radar Research and Development Establishment (RRDE). It was given its new name after a visit by Queen Elizabeth II in 1957. Both names were abbreviated to RRE. In 1976 the Signals Research and Development Establishment (SRDE), involved in communications research, joined the RRE to form the Royal Signals and Radar Establishment (RSRE). The two groups had been closely associated since before the opening of World War II, when the predecessor to RRDE was formed as a small group within the Air Ministry's research centre in Bawdsey Manor in Suffolk. Forced to leave Bawdsey due to its exposed location on the east coast of England, both groups moved several times before finally settling in separate locations in Malvern beginn ...

HIV Rev Response Element
The HIV-1 Rev response element (RRE) is a highly structured, ~350 nucleotide RNA segment present in the Env coding region of unspliced and partially spliced viral mRNAs. In the presence of the HIV-1 accessory protein Rev, HIV-1 mRNAs that contain the RRE can be exported from the nucleus to the cytoplasm for downstream events such as translation and virion packaging. RRE and HIV-1 biology Early phase The HIV-1 genome contains a single promoter and uses multiple reading frames and alternative splicing to encode 15 proteins from a single pre-mRNA species. Transcription from an integrated HIV-1 provirus generates a single 9 kilobase (kb) pre-mRNA containing multiple splice sites and nuclear retention signals. In the early phase of the viral life cycle, this pre-RNA is completely spliced to RRE-free, 2 kb messages. These smaller messages are then transported from the nucleus to the cytoplasm via standard mRNA nuclear export pathways (see Figure). One of these small, 2kb mess ...

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. Rad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malvern, Worcestershire
Malvern is a spa town and civil parish in Worcestershire, England. It lies at the foot of the Malvern Hills, a designated Area of Outstanding Natural Beauty. The centre of Malvern, Great Malvern, is a historic conservation area, which grew dramatically in Victorian times due to the natural mineral water springs in the vicinity, including Malvern Water. At the 2011 census it had a population of 29,626. It includes Great Malvern on the steep eastern flank of the Malvern Hills, as well as the former independent urban district of Malvern Link. Many of the major suburbs and settlements that comprise the town are separated by large tracts of open common land and fields, and together with smaller civil parishes adjoining the town's boundaries and the hills, the built up area is often referred to collectively as The Malverns. Archaeological evidence suggests that Bronze Age people had settled in the area around 1000 BC, although it is not known whether these settlements were permane ...

Royal Signals And Radar Establishment
The Royal Signals and Radar Establishment (RSRE) was a scientific research establishment within the Ministry of Defence (MoD) of the United Kingdom. It was located primarily at Malvern in Worcestershire, England. The RSRE motto was ''Ubique Sentio'' (Latin for "I sense everywhere"). History RSRE was formed in 1976 by an amalgamation of previous research organizations; these included the Royal Radar Establishment (RRE), itself derived from the World War II-era Telecommunications Research Establishment, the Signals Research and Development Establishment (SRDE) in Christchruch, Dorset, and the Services Electronic Research Laboratory (SERL) at Baldock. Beginning in 1979, the SRDE and SERL moved to Malvern to join the RRE's location.EdsRobert Budand Philip Gummett, ''Cold War Hot Science: Applied Research in Britain's Defence Laboratories 1945-1990'', Harwood, 1999 There were several out-stations in Worcestershire, including the ex-RAF airfields at Defford and Pershore and ...

Signals Research And Development Establishment
__NOTOC__ The Signals Research and Development Establishment (SRDE) was a British government military research establishment, based in Christchurch, Dorset from 1943 until it merged with the Royal Radar Establishment (RRE) in Malvern, Worcestershire to form the Royal Signals and Radar Establishment (RSRE) in 1976. Its focus was military communications (signals). History The establishment had its origins in the Royal Engineers Wireless Telegraphy Experimental Section founded at Aldershot in the very early part of the twentieth century. It moved to Woolwich, initially into the former Royal Dockyard (at that time a military stores depot) where it formed part of the Inspectorate of Royal Engineers Stores, before moving on to Woolwich Common. In 1914 it was operating out of a van at Woolwich, but in 1916 it settled into its own premises, becoming the Signals Experimental Establishment. The establishment was renamed SRDE at the start of the Second World War; it moved briefly to Horsham b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Army
The British Army is the principal land warfare force of the United Kingdom, a part of the British Armed Forces along with the Royal Navy and the Royal Air Force. , the British Army comprises 79,380 regular full-time personnel, 4,090 Gurkhas, and 28,330 volunteer reserve personnel. The modern British Army traces back to 1707, with antecedents in the English Army and Scots Army that were created during the Restoration in 1660. The term ''British Army'' was adopted in 1707 after the Acts of Union between England and Scotland. Members of the British Army swear allegiance to the monarch as their commander-in-chief, but the Bill of Rights of 1689 and Claim of Right Act 1689 require parliamentary consent for the Crown to maintain a peacetime standing army. Therefore, Parliament approves the army by passing an Armed Forces Act at least once every five years. The army is administered by the Ministry of Defence and commanded by the Chief of the General Staff. The Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar Research And Development Establishment
The Radar Research and Development Establishment, RRDE for short, was a civilian research organization run by the United Kingdom's Ministry of Supply that primarily studied the development of radar for British Army use. The group traces its history to the Searchlight Experimental Establishment which moved to RAF Biggin Hill in 1924, and the "Army Cell" operating at Bawdsey Manor researching radar beside their Air Ministry counterparts. In 1941 the Army groups merged and moved to Christchurch, Dorset and were renamed the Air Defence Research and Development Establishment. In May 1942 the group moved again, this time to an inland location at Malvern, Worcestershire, and were once again renamed to become the RRDE. Their Air Ministry counterparts, who had also moved to the Dorset area and been renamed the Telecommunications Research Establishment (TRE), joined them in Malvern over the next few months. The RRDE retained their name until 1953 when they merged with the TRE to form the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Proximity Fuse
A proximity fuze (or fuse) is a Fuze (munitions), fuze that detonates an Explosive material, explosive device automatically when the distance to the target becomes smaller than a predetermined value. Proximity fuzes are designed for targets such as planes, missiles, ships at sea, and ground forces. They provide a more sophisticated trigger mechanism than the common contact fuze or timed fuze. It is estimated that it increases the lethality by 5 to 10 times, compared to these other fuzes. Background Before the invention of the proximity fuze, detonation was induced by direct contact, a timer set at launch or an altimeter. All of these earlier methods have disadvantages. The probability of a direct hit on a small moving target is low; a shell that just misses the target will not explode. A time- or height-triggered fuze requires good prediction by the gunner and accurate timing by the fuze. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dundee
Dundee (; sco, Dundee; gd, Dùn Dè or ) is Scotland's fourth-largest city and the 51st-most-populous built-up area in the United Kingdom. The mid-year population estimate for 2016 was , giving Dundee a population density of 2,478/km2 or 6,420/sq mi, the second-highest in Scotland. It lies within the eastern central Lowlands on the north bank of the Firth of Tay, which feeds into the North Sea. Under the name of Dundee City, it forms one of the 32 council areas used for local government in Scotland. Within the boundaries of the historic county of Angus, the city developed into a burgh in the late 12th century and established itself as an important east coast trading port. Rapid expansion was brought on by the Industrial Revolution, particularly in the 19th century when Dundee was the centre of the global jute industry. This, along with its other major industries, gave Dundee its epithet as the city of "jute, jam and journalism". Today, Dundee is promoted as "One City, ...
