LHC's D-meson study wraps up antimatter 'flip' story. 28 February 2013Last updated at 11:05 GMT By Jason Palmer Science and technology reporter, BBC News The LHCb experiment has an established record studying these matter-antimatter "flips" Researchers at the Large Hadron Collider have witnessed particles called D-mesons flipping from matter into antimatter and back.
Antimatter is just like normal matter, but with opposite electric charge. Such "oscillations" are well known among three other particle types, but this is the first time D-mesons have been seen doing it in a single study. The team behind the collider's LHCb detector have put their results on the Arxiv repository. The manuscript will be published in Physical Review Letters.
In the complicated zoo of subatomic physics, particles routinely decay into other particles, or spontaneously change from a matter type to their antimatter counterparts. This "oscillation" forms an important part of the theory that attempts to tame the zoo - the Standard Model. Continue reading the main story. Encyclopedia of Fantasy (1997) Wurts, Janny.
Behemoth. Behemoth (/bɨˈhiːməθ/ or /ˈbiː.əməθ/, also /ˈbeɪ.əmɔːθ/; Hebrew: בהמות, behemoth (modern: behemot)) is a beast mentioned in Job 40:15–24. Suggested identities range from a mythological creature to an elephant, hippopotamus, rhinoceros or crocodile. Some creationists believe it to be a description of a sauropod.[1] Metaphorically, the name has come to be used for any extremely large or powerful entity. Plural as singular[edit] Job 40 is an example of the use of a plural noun suffix to mean "great", rather than plural. The feminine plural Hebrew noun behemoth is also used in Joel 1:20. [citation needed] Description[edit] Leviathan is identified figuratively with both the primeval sea (Job 3:8, Psalms 74:13) and in apocalyptic literature – describing the end-time – as that adversary, the Devil, from before creation who will finally be defeated.
Later Jewish writings[edit] Identity[edit] Since the 17th century CE there have been many attempts to identify Behemoth. Literary references[edit] Paraceratherium. Paraceratherium, also commonly known as Indricotherium or Baluchitherium (see taxonomic discussion below), is an extinct genus of gigantic hornless rhinoceros-like mammals of the family Hyracodontidae, endemic to Eurasia and Asia during the Oligocene epoch.[2] It was first discovered in 1910 in Balochistan of what is now Pakistan, hence the name, during an expedition by the English paleontologist and Cambridge University Museum of Zoology director Sir Clive Forster Cooper.[3] Description[edit] Restoration Paraceratherium is regarded as the largest land mammal known, with the largest species having an estimated mean adult mass of 11 t (12 tons)[4] and the largest individual known estimated at 4.8 m (16 ft) tall at the shoulders, 8.0 m (26.2 ft) in length from nose to rump, and 16 t (18 tons) in weight.[5] Paraceratherium was a browsing herbivorous perissodactyl that stripped leaves from trees with its downward-pointing, tusk-like upper teeth that occluded forward-pointing lower teeth.
Biology. Asperger syndrome. Asperger syndrome (AS), also known as Asperger disorder (AD) or simply Asperger's, is an autism spectrum disorder (ASD) that is characterized by significant difficulties in social interaction and nonverbal communication, alongside restricted and repetitive patterns of behavior and interests. It differs from other autism spectrum disorders by its relative preservation of linguistic and cognitive development. Although not required for diagnosis, physical clumsiness and atypical (peculiar, odd) use of language are frequently reported.[1][2] The syndrome is named after the Austrian pediatrician Hans Asperger who, in 1944, studied and described children in his practice who lacked nonverbal communication skills, demonstrated limited empathy with their peers, and were physically clumsy.[3] The modern conception of Asperger syndrome came into existence in 1981[4] and went through a period of popularization,[5][6] becoming standardized as a diagnosis in the early 1990s.

Jorge Francisco Isidoro Luis Borges, KBE (Spanish: [ˈxorxe ˈlwis ˈβorxes] In 1914 his family moved to Switzerland, where he studied at the Collège de Genève. The family travelled widely in Europe, including stays in Spain. On his return to Argentina in 1921, Borges began publishing his poems and essays in surrealist literary journals. He also worked as a librarian and public lecturer. In 1955 he was appointed director of the National Public Library and professor of Literature at the University of Buenos Aires.
His international reputation was consolidated in the 1960s, aided by his works being available in English, by the Latin American Boom and by the success of García Márquez's One Hundred Years of Solitude.[6] Writer and essayist J.

Qwiki. Nootropic. Nootropics (/noʊ.əˈtrɒpɨks/ noh-ə-TROP-iks), also referred to as smart drugs, memory enhancers, neuro enhancers, cognitive enhancers, and intelligence enhancers, are drugs, supplements, nutraceuticals, and functional foods that improve one or more aspects of mental function, such as working memory, motivation, and attention.[1][2] The word nootropic was coined in 1972 by the Romanian Dr.
Corneliu E. Giurgea,[3][4] derived from the Greek words νους nous, or "mind", and τρέπειν trepein meaning to bend or turn.[5] Availability and prevalence[edit] At present, there are only a few drugs which have been shown to improve some aspect of cognition in medical reviews. [citation needed] Many more are in different stages of development.[6] The most commonly used class of drug is stimulants, such as caffeine.[7] Academic use[edit] Surveys suggest that 3–11% of American students and 0.7–4.5% of German students have used cognitive enhancers in their lifetime.[11][12][13] Side effects[edit] Drugs[edit]
