Disk (mathematics)
In geometry, a disk (also spelled disc). is the region in a plane bounded by a circle. A disk is said to be ''closed'' if it contains the circle that constitutes its boundary, and ''open'' if it does not. For a radius, r, an open disk is usually denoted as D_r and a closed disk is \overline. However in the field of topology the closed disk is usually denoted as D^2 while the open disk is \operatorname D^2. Formulas In Cartesian coordinates, the ''open disk'' of center (a, b) and radius ''R'' is given by the formula :D=\ while the ''closed disk'' of the same center and radius is given by :\overline=\. The area of a closed or open disk of radius ''R'' is π''R''2 (see area of a disk). Properties The disk has circular symmetry. The open disk and the closed disk are not topologically equivalent (that is, they are not homeomorphic), as they have different topological properties from each other. For instance, every closed disk is compact whereas every open disk is not compact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glossary Of Plant Morphology
This page provides a glossary of plant morphology. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. This page provides help in understanding the numerous other pages describing plants by their various taxa. The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology. This glossary primarily includes terms that deal with vascular plants (ferns, gymnosperms and angiosperms), particularly flowering plants (angiosperms). Non-vascular plants (bryophytes), with their different evolutionary background, tend to have separate terminology. Although plant morphol ...

Intervertebral Disc
An intervertebral disc (or intervertebral fibrocartilage) lies between adjacent vertebrae in the vertebral column. Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine. Structure Intervertebral discs consist of an outer fibrous ring, the anulus fibrosus disci intervertebralis, which surrounds an inner gel-like center, the nucleus pulposus. The ''anulus fibrosus'' consists of several layers (laminae) of fibrocartilage made up of both type I and type II collagen. Type I is concentrated toward the edge of the ring, where it provides greater strength. The stiff laminae can withstand compressive forces. The fibrous intervertebral disc contains the ''nucleus pulposus'' and this helps to distribute pressure evenly across the disc. This prevents the development of stress concentrations which could cause damage to the underlying vertebrae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Symposium On Distributed Computing
The International Symposium on Distributed Computing (DISC) is an annual academic conference for refereed presentations, whose focus is the theory, design, analysis, implementation, and application of distributed systems and networks. The Symposium is organized in association with the European Association for Theoretical Computer Science (EATCS). The Edsger W. Dijkstra Prize in Distributed Computing is presented alternately at DISC and at the ACM Symposium on Principles of Distributed Computing (PODC). History DISC dates back to 1985, when it began as a biannual Workshop on Distributed Algorithms on Graphs (WDAG); it became annual in 1989. The name changed to the present one in 1998.DISC in .

Domestic International Sales Corporation
The domestic international sales corporation is a concept unique to tax law in the United States. In 1971, the U.S. Congress voted to use U.S. tax law to subsidize exports of U.S.-made goods. The initial mechanism was through a Domestic International Sales Corporation (DISC), an entity with no substance which received tax benefits. Today, shareholders of a DISC continue to receive reduced income tax rates on qualifying income from exports of U.S.-made goods. A DISC is a U.S. corporation that has elected DISC status and meets certain other largely symbolic requirements. A corporation so electing is not subject to U.S. Federal income tax. Properly structured, a DISC has no activities other than on paper and no activities not related to the export of qualifying goods. Mechanism for benefit: A DISC contracts with a producer or reseller of U.S.-made goods or provider of certain qualifying construction-related services to provide "services" to such related supplier for a fee. The fee is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devrimci İşçi Sendikaları Konfederasyonu
The Confederation of Progressive Trade Unions of Turkey ( Turkish: ''Türkiye Devrimci İşçi Sendikaları Konfederasyonu'', DİSK) is one of the four major national trade union centres in Turkey. It was founded in 1967 as a breakaway union from the Confederation of Turkish Trade Unions, and has a membership of 327,000. DİSK is affiliated with the International Trade Union Confederation, World Federation of Trade Unions, Trade Union Advisory Committee to the OECD and the European Trade Union Confederation. Development until the ban in 1980 DİSK was founded by Kemal Türkler, Riza Kuas, İbrahim Güzelce, Kemal Nebioğlu and Mehmet Alpdündar representing Türkiye Maden-İş, Lastik-İş, Basin-İş, Türkiye Gıda-İş and Türk Maden-İş, respectively. All of these unions were until that time affiliated to Türk-İş, except Gida-İş which was independent. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defence Intelligence And Security Centre
The Joint Intelligence Training Group (JITG) is the location of the headquarters of both the Defence College of Intelligence and the British Army Intelligence Corps. It is located at Chicksands, Bedfordshire, approximately north of London. The site was formerly known as the Defence Intelligence and Security Centre (DISC) since its move from Ashford in 1997. The site was renamed as JITG on 1 January 2015. Site History Chicksands was the site of RAF Chicksands, an RAF signals collection station during and after the Second World War; during the war, it was one of the "Y-Stations" which sent intercepted signals to the Government Code and Cypher School (GC&CS) at Bletchley Park, where ciphers and codes of several Axis countries were decrypted, most importantly the ciphers generated by the German Enigma and Lorenz machines. The station was used by the United States Air Force from 1950 to 1995, also for signals collection, being the location for its first diameter FLR-9 directi ...

Disk Storage
Disk storage (also sometimes called drive storage) is a general category of storage mechanisms where data is recorded by various electronic, magnetic, optical, or mechanical changes to a surface layer of one or more rotating disks. A disk drive is a device implementing such a storage mechanism. Notable types are the hard disk drive (HDD) containing a non-removable disk, the floppy disk drive (FDD) and its removable floppy disk, and various optical disc drives (ODD) and associated optical disc media. (The spelling ''disk'' and ''disc'' are used interchangeably except where trademarks preclude one usage, e.g. the Compact Disc logo. The choice of a particular form is frequently historical, as in IBM's usage of the ''disk'' form beginning in 1956 with the " IBM 350 disk storage unit".) Background Audio information was originally recorded by analog methods (see Sound recording and reproduction). Similarly the first video disc used an analog recording method. In the music indu ...

Death-inducing Signaling Complex
The death-inducing signaling complex or DISC is a multi-protein complex formed by members of the death receptor family of apoptosis-inducing cellular receptors. A typical example is FasR, which forms the DISC upon trimerization as a result of its ligand (FasL) binding. The DISC is composed of the death receptor, FADD, and caspase 8. It transduces a downstream signal cascade resulting in apoptosis. Description The Fas ligands, or cytotoxicity-dependent APO-1-associated proteins, physically associate with APO-1 (also known as the Fas receptor, or CD95), a tumor necrosis factor containing a functional death domain. This association leads to the formation of the DISC, thereby inducing apoptosis. The entire process is initiated when the cell registers the presence of CD95L, the cognate ligand for APO-1. Upon binding, the CAP proteins and procaspase-8 (composed of FLICE, MACH, and Mch5) bind to CD95 through death domain and death effector domain interactions. Procaspase-8 activation is ...
