Atomic Nucleus
The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment. After the discovery of the neutron in 1932, models for a nucleus composed of protons and neutrons were quickly developed by Dmitri Ivanenko and Werner Heisenberg. An atom is composed of a positively charged nucleus, with a cloud of negatively charged electrons surrounding it, bound together by electrostatic force. Almost all of the mass of an atom is located in the nucleus, with a very small contribution from the electron cloud. Protons and neutrons are bound together to form a nucleus by the nuclear force. The diameter of the nucleus is in the range of () for hydrogen (the diameter of a single proton) to about for uranium. These dimensions are much smaller than the diameter of the atom itself (nucleus + electron cloud), by a factor of about 26,634 (uranium atomic radiu ...

Nuclear C*-algebra
In the mathematical field of functional analysis, a nuclear C*-algebra is a C*-algebra A such that the injective and projective C*- cross norms on A \oplus B are the same for every C*-algebra B. This property was first studied by under the name "Property T", which is not related to Kazhdan's property T. Characterizations Nuclearity admits the following equivalent characterizations: * The identity map, as a completely positive map, approximately factors through matrix algebras. By this equivalence, nuclearity can be considered a noncommutative analogue of the existence of partitions of unity. * The enveloping von Neumann algebra is injective. * It is amenable as a Banach algebra. * It is isomorphic to a C*-subalgebra B of the Cuntz algebra \mathcal_2 with the property that there exists a conditional expectation In probability theory, the conditional expectation, conditional expected value, or conditional mean of a random variable is its expected value – the value it woul ...

Nucleation
In thermodynamics, nucleation is the first step in the formation of either a new thermodynamic phase or structure via self-assembly or self-organization within a substance or mixture. Nucleation is typically defined to be the process that determines how long an observer has to wait before the new phase or self-organized structure appears. For example, if a volume of water is cooled (at atmospheric pressure) below 0°C, it will tend to freeze into ice, but volumes of water cooled only a few degrees below 0°C often stay completely free of ice for long periods (supercooling). At these conditions, nucleation of ice is either slow or does not occur at all. However, at lower temperatures nucleation is fast, and ice crystals appear after little or no delay. Nucleation is a common mechanism which generates first-order phase transitions, and it is the start of the process of forming a new thermodynamic phase. In contrast, new phases at continuous phase transitions start to form immedi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nucleolus
The nucleolus (, plural: nucleoli ) is the largest structure in the nucleus of eukaryotic cells. It is best known as the site of ribosome biogenesis, which is the synthesis of ribosomes. The nucleolus also participates in the formation of signal recognition particles and plays a role in the cell's response to stress. Nucleoli are made of proteins, DNA and RNA, and form around specific chromosomal regions called nucleolar organizing regions. Malfunction of nucleoli can be the cause of several human conditions called "nucleolopathies" and the nucleolus is being investigated as a target for cancer chemotherapy. History The nucleolus was identified by bright-field microscopy during the 1830s. Little was known about the function of the nucleolus until 1964, when a study of nucleoli by John Gurdon and Donald Brown in the African clawed frog ''Xenopus laevis'' generated increasing interest in the function and detailed structure of the nucleolus. They found that 25% of the frog e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Man On The Rocks
''Man on the Rocks'' is the twenty-fifth studio album by British musician Mike Oldfield, released on 3 March 2014 on the Virgin EMI label. The album is Oldfield's second full album of exclusively songs with no long or instrumental pieces, the first being 1989's ''Earth Moving''. Recording and production ''Man on the Rocks'' was produced by Stephen Lipson together with Oldfield. The album features bassist Leland Sklar, drummer John Robinson, keyboardist Matt Rollings, guitarist Michael Thompson and singer Luke Spiller together with Oldfield himself on guitar. The backing tracks were recorded during June 2013 in Studio D of Village Studios, Los Angeles with producer Steve Lipson; Oldfield participated in these sessions via Skype. Oldfield has also recorded part of the album in his home studio in the Bahamas. Oldfield's electric guitar sound on the album is primarily a Fender Telecaster combined with the Avid Eleven software plug-in. The album marks a return of Oldfield to a ...

Nuclear (Ryan Adams Song)
"Nuclear" is a song by singer-songwriter Ryan Adams from his 2002 album ''Demolition'', the only single from the album. The song was recorded during Adams' July 2001 sessions with the Pinkhearts in Nashville. In 2002, Adams spoke with CNN about the song: "I guess it's Britpop for Americans. I don't know what it is, really, but the lyrics are funny. There's actually a really funny line in it that says, 'I saw her and the Yankees lost to the Braves.' If you're from Atlanta, that's not a very nice thing to say. It's sort of referring to the fact that the Braves never win." (The Atlanta Braves lost both the 1996 and 1999 World Series to the New York Yankees.) Among the b-sides included on the various "Nuclear" singles are the non-album tracks "Blue" and "Song For Keith". Adams co-wrote "Blue" with Julianna Raye, and the song comes from the ''48 Hours'' sessions. "Song For Keith" is a tribute to Rolling Stones guitarist Keith Richards and was recorded during ''The Pinkhearts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear (band)
Nuclear is a Chilean thrash metal band founded in Arica, Chile, in 1998. The band has gone through several lineup changes and is currently signed to the label Candlelight Records. History Nuclear was formed in 1995 under the name Escoria, but it was not until 1997 when the first recording was released. After the dissolution in 2001, the name of Escoria turned to Nuclear and the original members Sebastian Puente, Francisco and Eugene Haussmann Sudy are maintained in a constant line up that continues to date. The band has released four studio albums and toured in several countries sharing the stage with acts like Testament, Forbidden, Voivod, Grave, Hirax, 1349, Anthrax, Destruction, Witchcraft, Hate Eternal, Absu, At the Gates among others. During 2013, the band released their first live DVD called Sick Mosh and Inner Hate, a split vinyl, which were put in launching and distributed by the Chilean label Sick Bangers. Tour and constant releases of the band caught the attenti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Family
A nuclear family, elementary family, cereal-packet family or conjugal family is a family group consisting of parents and their children (one or more), typically living in one home residence. It is in contrast to a single-parent family, the larger extended family, or a family with more than two parents. Nuclear families typically center on a heterosexual married couple which may have any number of children. There are differences in definition among observers. Some definitions allow only biological children that are full-blood siblings and consider adopted or half and step siblings a part of the immediate family, but others allow for a step-parent and any mix of dependent children, including stepchildren and adopted children. Some sociologists and anthropologists consider the nuclear family as the most basic form of social organization, while others consider the extended family structure to be the most common family structure in most cultures and at most times. The term ''nuclear fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear DNA
Nuclear DNA (nDNA), or nuclear deoxyribonucleic acid, is the DNA contained within each cell nucleus of a eukaryotic organism. It encodes for the majority of the genome in eukaryotes, with mitochondrial DNA and plastid DNA coding for the rest. It adheres to Mendelian inheritance, with information coming from two parents, one male and one female—rather than matrilineally (through the mother) as in mitochondrial DNA. Structure Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells. Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin. Each strand is a long polymer chain of repeating nucleotides. Each nucleotide is composed of a five-carbon sugar, a phosphate group, and an organic base. Nucleotides are distinguished by their bases: purines, large bases that include adenine and guanine; and pyr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cell Nucleus
The cell nucleus (pl. nuclei; from Latin or , meaning ''kernel'' or ''seed'') is a membrane-bound organelle found in eukaryotic cells. Eukaryotic cells usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others including osteoclasts have many. The main structures making up the nucleus are the nuclear envelope, a double membrane that encloses the entire organelle and isolates its contents from the cellular cytoplasm; and the nuclear matrix, a network within the nucleus that adds mechanical support. The cell nucleus contains nearly all of the cell's genome. Nuclear DNA is often organized into multiple chromosomes – long stands of DNA dotted with various proteins, such as histones, that protect and organize the DNA. The genes within these chromosomes are structured in such a way to promote cell function. The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Congruence
In mathematics, a semigroup is an algebraic structure consisting of a set together with an associative internal binary operation on it. The binary operation of a semigroup is most often denoted multiplicatively: ''x''·''y'', or simply ''xy'', denotes the result of applying the semigroup operation to the ordered pair . Associativity is formally expressed as that for all ''x'', ''y'' and ''z'' in the semigroup. Semigroups may be considered a special case of magmas, where the operation is associative, or as a generalization of groups, without requiring the existence of an identity element or inverses. The closure axiom is implied by the definition of a binary operation on a set. Some authors thus omit it and specify three axioms for a group and only one axiom (associativity) for a semigroup. As in the case of groups or magmas, the semigroup operation need not be commutative, so ''x''·''y'' is not necessarily equal to ''y''·''x''; a well-known example of an operation that is as ...
