Roentgenium
Roentgenium is a chemical element with the symbol Rg and atomic number 111. It is an extremely radioactive synthetic element that can be created in a laboratory but is not found in nature. The most stable known isotope, roentgenium-282, has a half-life of 100 seconds, although the unconfirmed roentgenium-286 may have a longer half-life of about 10.7 minutes. Roentgenium was first created in 1994 by the GSI Helmholtz Centre for Heavy Ion Research near Darmstadt, Germany. It is named after the physicist Wilhelm Röntgen ( also spelled Roentgen), who discovered X-rays. Only a few roentgenium atoms have ever been synthesized, and they have no current practical application beyond that of scientific study. In the periodic table, it is a d-block transactinide element. It is a member of the 7th period and is placed in the group 11 elements, although no chemical experiments have been carried out to confirm that it behaves as the heavier homologue to gold in group 11 as the ninth m ...

Rg Chromaticity
The rg chromaticity space, two dimensions of the ''normalized RGB'', or rgb, space, is a chromaticity space, a two-dimensional color space in which there is no intensity information. In the RGB color space a pixel is identified by the intensity of red, green, and blue primary colors. Therefore, a bright red can be represented as (R,G,B) (255,0,0), while a dark red may be (40,0,0). In the normalized rgb space or rg space, a color is represented by the proportion of red, green, and blue in the color, rather than by the intensity of each. Since these proportions must always add up to a total of 1, we are able to quote just the red and green proportions of the color, and can calculate the blue value if necessary. Conversion between RGB and RG Chromaticity Given a color (R,G,B) where R, G, B = intensity of red, green and blue, this can be converted to color (r,g,b) where r, g, b imply the proportion of red, green and blue in the original color: r = \frac g = \frac b = \f ...

Röhm Gesellschaft
Röhm Gesellschaft, often referred to as RG, is a German brand of firearms and related shooting equipment. RG developed as a diversification of Röhm GmbH in the 1950s. After 1968, RG Industries was established as a US division in Miami and operated until 1986. In 2010, the RG brand was acquired by Umarex GmbH & Co. KG. Röhm's RG-14 handgun, used in an assassination attempt on then US President Ronald Reagan, was referred to in 1981 as a Saturday night special, a cheaply manufactured firearm of perceived low quality, believed at the time to be favored by criminals. History In the early 1950s, Röhm GmbH of Sontheim/Brenz, which was traditionally focused on the production of chucking tools, diversified its product line and began to produce gas alarm guns, flare guns, starting pistols and handguns. Röhm's product line of firearms was primarily established under the brand name ''RG''. Following importation limits imposed on handguns by the 1968 Gun Control Act, RG esta ...

RG Veda
is a manga created by Clamp, consisting of ten volumes in all. It was first published in Japan in 1989 as Clamp's debut manga. The story features elements of Vedic mythology; the title itself is pronounced ''Rigveda'', the name of one of the four Vedas. The series is known for its extravagant and richly detailed art. It inspired a 2-episode anime OVA that was released through 1991 to 1992. The OVAs were licensed by Central Park Media, while Manga Entertainment licensed it in the UK and Australia, with a different English dub. The ''RG Veda'' manga has been translated and released in many different languages. Tokyopop has released English versions in the United States. However, they have since lost the rights, and Dark Horse Comics recently acquired the series, it being published in omnibus form in 2016. Plot Three hundred years ago, the god of thunder, Taishakuten, rebelled against the Heavenly Emperor, killing both him and the guardian god Ashura-ō. With the help ...

RG Line
RG Line Oy Ab was a Finnish shipping company founded in 2001 that operated a ferry line between Vaasa, Finland and Umeå, Sweden until the end of 2012. Nowadays the Vaasa-Umeå line is operated by Wasa Line. The company was founded in 2001 by well known Vaasa-based businessman Rabbe Grönblom, just months after Silja Line had put their traffic on Kvarken / Merenkurkku to an end because of a decision in the EU to stop taxfree sales on travels between member states. RG Line bought Silja's M/S ''Fennia'' and renamed her to M/S ''Casino Express'', the ship was put in traffic on the route Vaasa–Umeå on 16 May 2001. At first RG Line profiled the ship as a ship where you could have fun and party, much like the ferries who trafficked Kvarken in the tax-free times. However, it did not become a success; people did not want to cruise any more. The blackjack and roulette tables they had added to get a casino feeling were removed before a year had passed. The company focused on ordin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renormalization Group
In theoretical physics, the term renormalization group (RG) refers to a formal apparatus that allows systematic investigation of the changes of a physical system as viewed at different scales. In particle physics, it reflects the changes in the underlying force laws (codified in a quantum field theory) as the energy scale at which physical processes occur varies, energy/momentum and resolution distance scales being effectively conjugate under the uncertainty principle. A change in scale is called a scale transformation. The renormalization group is intimately related to ''scale invariance'' and ''conformal invariance'', symmetries in which a system appears the same at all scales (so-called self-similarity). As the scale varies, it is as if one is changing the magnifying power of a notional microscope viewing the system. In so-called renormalizable theories, the system at one scale will generally be seen to consist of self-similar copies of itself when viewed at a smaller s ...

American Mensa
Mensa is the largest and oldest high-IQ society in the world. It is a non-profit organisation open to people who score at the 98th percentile or higher on a standardised, supervised IQ or other approved intelligence test. Mensa formally comprises national groups and the umbrella organisation Mensa International, with a registered office in Caythorpe, Lincolnshire, England, which is separate from the British Mensa office in Wolverhampton. The word ''mensa'' (, ) is Latin for ' table', as is symbolised in the organisation's logo, and was chosen to demonstrate the round-table nature of the organisation; the coming together of equals. History Roland Berrill, an Australian barrister, and Lancelot Ware, a British scientist and lawyer, founded Mensa at Lincoln College, in Oxford, England in 1946, with the intention of forming a society for the most intelligent, with the only qualification being a high IQ. The society was ostensibly to be non-political in its aims, and free from a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capital In The Twenty-First Century
''Capital in the Twenty-First Century'' (french: Le Capital au XXIe siècle) is a book written by French economist Thomas Piketty. It focuses on wealth and income inequality in Europe and the United States since the 18th century. It was initially published in French (as ''Le Capital au XXIe siècle'') in August 2013; an English translation by Arthur Goldhammer followed in April 2014. The book's central thesis is that when the rate of return on capital (''r'') is greater than the rate of economic growth (''g'') over the long term, the result is concentration of wealth, and this unequal distribution of wealth causes social and economic instability. Piketty proposes a global system of progressive wealth taxes to help reduce inequality and avoid the vast majority of wealth coming under the control of a tiny minority. At the end of 2014, Piketty released a paper where he stated that he does not consider the relationship between the rate of return on capital and the rate of economi ...

Ibanez RG
The Ibanez RG is a series of electric guitars produced by Hoshino Gakki and one of the best-selling superstrat-style guitars ever made. The first model in the series, the RG550, was originally released in 1987 and advertised as part of the Roadstar series. That series was renamed "RG" in 1992 and all models since are simply known as RGs. It rose in popularity throughout the 1980s and had the features that musicians in the rising shred and thrash metal movements of that time were looking for: a "fast" neck, comfortable body, powerful pickups, and a reliable tremolo system. The RG series has the most subtypes of any Ibanez model and is the most popular series of Ibanez electric guitars produced by Hoshino Gakki. The RG's deep cutaway, flatter fingerboard and extended fret range (24 frets as standard) has made it one of the most popular guitars for rock and heavy metal music. Origin and name The Ibanez RG was originally designed in 1987, the same year as Steve Vai's signatu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direction Centrale Des Renseignements Généraux
The ''Direction Centrale des Renseignements Généraux'' (Central Directorate of General Intelligence), often called ''Renseignements Généraux'' (RG), was the intelligence service of the French National Police, answerable to the ''Direction Générale de la Police Nationale'' (DGPN), and, ultimately, the Ministry of the Interior. It was also in charge of the monitoring of gambling places and horse racing ranges. On July 1, 2008, it was merged with the '' Direction de la surveillance du territoire'' into the new ''Direction centrale du renseignement intérieur''. Organisation The RG was subdivided into four sub-directorates: * Research * Analysis, prospective and society facts * Resources and methods * Games and casinos The RG employed 3 850 public servants of the Police. They were not covered by the defence classification (of their name, for instance), though some of them had access to have security clearance (some of the files are classified information).
