2-ring
In mathematics, a categorical ring is, roughly, a category equipped with addition and multiplication. In other words, a categorical ring is obtained by replacing the underlying set of a ring by a category. For example, given a ring ''R'', let ''C'' be a category whose objects are the elements of the set ''R'' and whose morphisms are only the identity morphisms. Then ''C'' is a categorical ring. But the point is that one can also consider the situation in which an element of ''R'' comes with a "nontrivial automorphism" (cf. Lurie). This line of generalization of a ring eventually leads to the notion of an ''E''''n''-ring. See also *Categorification *Higher-dimensional algebra In mathematics, especially ( higher) category theory, higher-dimensional algebra is the study of categorified structures. It has applications in nonabelian algebraic topology, and generalizes abstract algebra. Higher-dimensional categories A f ... References *Laplaza, M. Coherence for distributivity ...

Afar (album)
''Afar'' is the debut studio album of Ice Choir, the project of former The Pains of Being Pure at Heart drummer and The Depreciation Guild lead Kurt Feldman. It was released on July 31, 2012, by Underwater Peoples. It received mostly positive reviews from critics, with positive reviews highlighting Feldman's use of the 1980s influences and more varied responses criticizing the cheesiness. Production Towards the end of The Depreciation Guild, Kurt Feldman began writing music without any of the NES programming of the band's previous works, and the other members also started losing interest and focus of the project. Considering that it was much more "guitar-pop" than Ice Choir, there were certain limitations and aspects in writing that Feldman did not want to go through, so he decided to try new things and start over with a new project. ''Afar'' was written from October 2010 to May 2011 while on tour, with "The Ice Choir" as the first song written. ''Afar'' was produced from May 2011 ...

Ring Binder
Ring binders (loose leaf binders, looseleaf binders, or sometimes called files in Britain) are large folders that contain file folders or hole punched papers. These binders come in various sizes and can accommodate an array of paper sizes. These are held in the binder by circular or D-shaped retainers, onto which the contents are threaded. The rings themselves come in a variety of sizes, including , though other sizes are also available. The rings are usually spring-loaded, but can also be secured by lever arch mechanisms or other securing systems. The binders themselves are typically made from plastic with metal rings. Early designs were patented during the early 1890s to the early 1900s. History American Henry Tillinghast Sisson invented the three ring binder, receivinpatent no. 23506on April 5, 1859. German Friedrich Soennecken invented ring binders in 1886 in Bonn. He also registered a patent on November 14, 1886, for his ''Papierlocher für Sammelmappen'' ("paper hole ...

Bicyclic Molecule
In chemistry, a bicyclic molecule () is a molecule that features two joined rings. Bicyclic structures occur widely, for example in many biologically important molecules like α-thujene and camphor. A bicyclic compound can be carbocyclic (all of the ring atoms are carbons), or heterocyclic (the rings' atoms consist of at least two elements), like DABCO. Moreover, the two rings can both be aliphatic (''e.g.'' decalin and norbornane), or can be aromatic (''e.g.'' naphthalene), or a combination of aliphatic and aromatic (''e.g.'' tetralin). Three modes of ring junction are possible for a bicyclic compound: * In spirocyclic compounds, the two rings share only one single atom, the spiro atom, which is usually a quaternary carbon. An example of a spirocyclic compound is the photochromic switch spiropyran. * In fused/condensed bicyclic compounds, two rings share two adjacent atoms. In other words, the rings share one covalent bond, ''i.e.'' the so-called bridgehead atoms are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterocyclic Compounds, 2-ring
A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). Heterocyclic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of these heterocycles. Examples of heterocyclic compounds include all of the nucleic acids, the majority of drugs, most biomass (cellulose and related materials), and many natural and synthetic dyes. More than half of known compounds are heterocycles. 59% of US FDA-approved drugs contain nitrogen heterocycles. Classification The study of heterocyclic chemistry focuses especially on unsaturated derivatives, and the preponderance of work and applications involves unstrained 5- and 6-membered rings. Included are pyridine, thiophene, pyrrole, and furan. Another large class of heterocycles refers to those fused to benzene rings. For example, the fused benzene derivatives of pyridine, thiophene, pyrrole, and furan are quin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
