Homologation
Homologation (Greek ''homologeo'', ὁμολογέω, "to agree") is the granting of approval by an official authority. This may be a court of law, a government department, or an academic or professional body, any of which would normally work from a set of rules or standards to determine whether such approval should be given. The word may be considered very roughly synonymous with ''accreditation'', and in fact in French and Spanish may be used with regard to academic degrees (see apostille). ''Certification'' is another possible synonym, while ''to homologate'' is the infinitive verb form. In today's marketplace, for instance, products must often be homologated by some public agency to assure that they meet standards for such things as safety and environmental impact. A court action may also sometimes be homologated by a judicial authority before it can proceed, and the term has a precise legal meaning in the judicial codes of some countries. The equivalent process of testing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homologation Reaction
In organic chemistry, a homologation reaction, also known as homologization, is any chemical reaction that converts the reactant into the next member of the homologous series. A homologous series is a group of compounds that differ by a constant unit, generally a methylene () group. The reactants undergo a homologation when the number of a repeated structural unit in the molecules is increased. The most common homologation reactions increase the number of methylene () units in saturated chain within the molecule. For example, the reaction of aldehydes or ketones with diazomethane or methoxymethylenetriphenylphosphine to give the next homologue in the series. Examples of homologation reactions include: * Kiliani-Fischer synthesis, where an aldose molecule is elongated through a three-step process consisting of: *# Nucleophillic addition of cyanide to the carbonyl to form a cyanohydrin *# Hydrolysis to form a lactone *# Reduction to form the homologous aldose * Wittig reacti ...

Auto Racing
Auto racing (also known as car racing, motor racing, or automobile racing) is a motorsport involving the racing of automobiles for competition. Auto racing has existed since the invention of the automobile. Races of various sorts were organised, with the first recorded as early as 1867. Many of the earliest events were effectively Classic trials, reliability trials, aimed at proving these new machines were a practical mode of transport, but soon became an important way for automobile makers to demonstrate their machines. By the 1930s, specialist racing cars had developed. There are now numerous different categories, each with different rules and regulations. History The first prearranged match race of two self-powered road vehicles over a prescribed route occurred at 4:30 A.M. on August 30, 1867, between Ashton-under-Lyne and Old Trafford, a distance of eight miles. It was won by the carriage of Isaac Watt Boulton. Internal combustion auto racing events began soon after ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accreditation
Accreditation is the independent, third-party evaluation of a conformity assessment body (such as certification body, inspection body or laboratory) against recognised standards, conveying formal demonstration of its impartiality and competence to carry out specific conformity assessment tasks (such as certification, inspection and testing). Accreditation bodies are established in many economies with the primary purpose of ensuring that conformity assessment bodies are subject to oversight by an authoritative body. Accreditation bodies, that have been peer evaluated as competent, sign regional and international arrangements to demonstrate their competence. These accreditation bodies then assess and accredit conformity assessment bodies to the relevant standards. An authoritative body that performs accreditation is called an 'accreditation body'. The International Accreditation Forum (IAF) and International Laboratory Accreditation Cooperation (ILAC) provide international recognitio ...

Professional Certification
Professional certification, trade certification, or professional designation, often called simply ''certification'' or ''qualification'', is a designation earned by a person to assure qualification to perform a job or task. Not all certifications that use post-nominal letters are an acknowledgement of educational achievement, or an agency appointed to safeguard the public interest. Overview A certification is a third-party attestation of an individual's level of knowledge or proficiency in a certain industry or profession. They are granted by authorities in the field, such as professional societies and universities, or by private certificate-granting agencies. Most certifications are time-limited; some expire after a period of time (e.g., the lifetime of a product that required certification for use), while others can be renewed indefinitely as long as certain requirements are met. Renewal usually requires ongoing education to remain up-to-date on advancements in the field, evid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sportscar Racing
Sports car racing is a form of motorsport road racing which utilises sports cars that have two seats and enclosed wheels. They may be purpose-built prototypes or grand tourers based on road-going models. Broadly speaking, sports car racing is one of the main types of circuit auto racing, alongside open-wheel single-seater racing (such as Formula One), touring car racing (such as the British Touring Car Championship, which is based on 'saloon cars' as opposed to the 'exotics' seen in sports cars) and stock car racing (such as NASCAR). Sports car races are often, though not always, endurance races that are run over relatively large distances, and there is usually a larger emphasis placed on the reliability and efficiency of the car as opposed to outright speed of the driver. The FIA World Endurance Championship is an example of a sports car racing series. A type of hybrid between the purism of open-wheelers and the familiarity of touring car racing, this style is often associate ...

European Professional Qualification Directives
The main European legal instruments covering the mutual recognition of professional certification, professional qualificationsis: Directive 2005/36/EC on the recognition of professional qualifications. The directive covers the European Economic Area and has been amended several times. The directive provides a modern EU system of recognition of professional experience and promotes automatic recognition of professional experience across the EU. The qualifications of some professions, such as doctors and architects, have been extensively harmonised by Directive 2005/36/EC. The directive offers more general guidelines for other professions, that have not been specifically regulated this Directive, or other specific rules. Any form of work that would normally be restricted in a member state to people who had gained a professional qualification in that member state are also open to nationals of the EU (and member states of the European Economic Area) who have gained a similar professiona ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

2006 Winter Olympics
The 2006 Winter Olympics, officially the XX Olympic Winter Games ( it, XX Giochi olimpici invernali) and also known as Torino 2006, were a winter multi-sport event held from 10 to 26 February 2006 in Turin, Italy. This marked the second time Italy had hosted the Winter Olympics, the first being in 1956 in Cortina d'Ampezzo; Italy had also hosted the Summer Olympics in 1960 in Rome. Turin was selected as the host city for the 2006 Games in June 1999. The official motto of Torino 2006 was "Passion lives here". The Games' logo depicted a stylized profile of the Mole Antonelliana building, drawn in white and blue ice crystals, signifying the snow and the sky. The crystal web was also meant to portray the web of new technologies and the Olympic spirit of community. The 2006 Olympic mascots were Neve ("snow" in Italian), a female snowball, and Gliz, a male ice cube. Italy will host the Winter Olympics again in 2026, scheduled to be held in Milan and Cortina d'Ampezzo. Host ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luge
A luge is a small one- or two-person sled on which one sleds supine (face up) and feet-first. A luger steers by using the calf muscles to flex the sled's runners or by exerting opposite shoulder pressure to the seat. Racing sleds weigh for singles and for doubles. Luge is also the name of an Olympic sport. Lugers can reach speeds of 140 km/h (87 mph). Austrian Manuel Pfister reached a top speed of 154 km/h (96 mph) on a track in Whistler, Canada, prior to the 2010 Winter Olympics. Lugers compete against a timer in one of the most precisely timed sports in the world—to one thousandth of a second on artificial tracks. The first recorded use of the term "luge" dates to 1905 and derives from the Savoy/Swiss dialect of the French word ''luge'', meaning "small coasting sled". History The very practical use of sleds is ancient and widespread. The first recorded sled races took place in Norway sometime during the 15th century. The sport of luge, like th ...

Skeleton (sport)
Skeleton is a winter sliding sport in which a person rides a small sled, known as a skeleton bobsled (or -sleigh), down a frozen track while lying face down and head-first. The sport and the sled may have been named from the bony appearance of the sled. Unlike other sliding sports of bobsleigh and luge, the race always involves single riders. Like bobsleigh, but unlike luge, the race begins with a running start from the opening gate at the top of the course. The skeleton sled is thinner and heavier than the luge sled, and skeleton gives the rider more precise control of the sled. Skeleton is the slowest of the three sliding sports, as skeleton's face-down, head-first riding position is less aerodynamic than luge's face-up, feet-first ride. Previously, skeleton appeared in the Olympic program in St. Moritz, Switzerland, in 1928 and again in 1948. It was added permanently to the Olympic program for the 2002 Winter Olympics, at which stage a women's race was added. Durin ...

Speed Climbing
Speed climbing is a climbing discipline in which speed is the ultimate goal. Speed climbing is done on rocks, walls and poles and is only recommended for highly skilled and experienced climbers. Competition speed climbing, which takes place on an artificial standardized climbing wall, is the main form of speed climbing. However, there are other variations of speed climbing that take place outdoors. In pure speed climbing, time is everything but it is also common to record speed ascents while observing a particular climbing style or ethic. For example, there are many speed records in which the climb was done according to free climbing ethics. In popular culture speed climbing may be best known for a viral video featuring Dan Osman climbing Lover's Leap via the '' Bear's Reach'' route (5.7, 120+ meter) in 4 min 25 sec. This clip was originally featured in the movie ''Masters of Stone IV''. Competition speed climbing Competition speed climbing as governed by the International ...
