Compact Disc
The compact disc (CD) is a Digital media, digital optical disc data storage format that was co-developed by Philips and Sony to store and play digital audio recordings. In August 1982, the first compact disc was manufactured. It was then released in October 1982 in Japan and branded as ''Compact Disc Digital Audio, Digital Audio Compact Disc''. The format was later adapted (as CD-ROM) for general-purpose data storage. Several other formats were further derived, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video CD (VCD), Super Video CD (SVCD), Photo CD, Picture CD, Compact Disc-Interactive (CD-i) and Enhanced Music CD. Standard CDs have a diameter of and are designed to hold up to 74 minutes of uncompressed stereo digital audio or about 650 mebibyte, MiB of data. Capacity is routinely extended to 80 minutes and 700 mebibyte, MiB by arranging data more closely on the same sized disc. The Mini CD has various diameters ranging from ; t ...

Cadmium
Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 through 11. Cadmium and its congeners in group 12 are often not considered transition metals, in that they do not have partly filled ''d'' or ''f'' electron shells in the elemental or common oxidation states. The average concentration of cadmium in Earth's crust is between 0.1 and 0.5 parts per million (ppm). It was discovered in 1817 simultaneously by Stromeyer and Hermann, both in Germany, as an impurity in zinc carbonate. Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. Cadmium was used for a long time as a corrosion-resistant plating on steel, and cadmium compounds are used as red, orang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Community Of Democracies
The Community of Democracies (C.O.D), established in 2000, is an intergovernmental coalition of states. Its aim is to bring together governments, civil society and the private sector in the pursuit of the common goal of supporting democratic rules, expanding political participation, advancing and protecting democratic freedoms, and strengthening democratic norms and institutions around the world. The Warsaw Declaration had outlined the task of promoting democracy. It is disputed if the coalition qualifies as an International Organization in the legal sense. History The C.O.D was inaugurated at its first biennial ministerial conference hosted by the government of Poland in Warsaw on June 25 to June 27, 2000. The initiative was spearheaded by Polish Foreign Minister Bronisław Geremek and U.S. Secretary of State Madeleine Albright, along with six co-conveners: the governments of Chile, the Czech Republic, India, Mali, Portugal and the Republic of Korea. In total, 106 nations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil Defense
Civil defense ( en, region=gb, civil defence) or civil protection is an effort to protect the citizens of a state (generally non-combatants) from man-made and natural disasters. It uses the principles of emergency operations: prevention, mitigation, preparation, response, or emergency evacuation and recovery. Programs of this sort were initially discussed at least as early as the 1920s and were implemented in some countries during the 1930s as the threat of war and aerial bombardment grew. Civil-defense structures became widespread after authorities recognised the threats posed by nuclear weapons. Since the end of the Cold War, the focus of civil defense has largely shifted from responding to military attack to dealing with emergencies and disasters in general. The new concept is characterised by a number of terms, each of which has its own specific shade of meaning, such as ''crisis management'', '' emergency management'', ''emergency preparedness'', ''contingency planning' ...

Christian Democracy
Christian democracy (sometimes named Centrist democracy) is a political ideology that emerged in 19th-century Europe under the influence of Catholic social teaching and neo-Calvinism. It was conceived as a combination of modern democratic ideas and traditional Christian values, incorporating social justice and the social teachings espoused by the Catholic, Lutheran, Reformed, Pentecostal, and other denominational traditions of Christianity in various parts of the world. After World War II, Catholic and Protestant movements of neo-scholasticism and the Social Gospel shaped Christian democracy. On the traditional left-right political spectrum Christian Democracy has been difficult to pinpoint as Christian democrats rejected liberal economics and individualism and advocated state intervention, but simultaneously defended private property rights against excessive state intervention. This has meant that Christian Democracy has historically been considered centre left on eco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centro Democratico
Democratic Centre ( it, Centro Democratico, CD) is a centrist, Christian leftist and social-liberal political party in Italy. Most of its members, including its leader Bruno Tabacci, are former Christian Democrats. Since its beginnings, the CD has been also part of the centre-left coalition, centred around the Democratic Party (PD). The CD, along with the Italian Radicals and Forza Europa, was a founding member of More Europe (+E), a liberal party. As such, it was indirectly a member of the Alliance of Liberals and Democrats for Europe Party (ALDE Party) at the level of European Union. The CD had formed a partnership with the ALDE Party since the 2014 European Parliament election. History Foundation and 2013 general election The party was launched on 28 December 2012 as an electoral list and immediately joined Italy. Common Good, a centre-left coalition formed to contest the 2013 general election. The CD originally included large chunks of Alliance for Italy (ApI), led by ...

Centre Democrats (Netherlands)
The Centre Democrats ( nl, Centrum Democraten, CD) was a political party in the Netherlands. Founded in 1984 by members who split out from the Centre Party (CP), the Centre Democrats was joined one month later by the only CP Member of Parliament—Hans Janmaat. Janmaat went on to become the leader of the party, which subsequently became strongly centered on his person. The newly formed Centre Democrats represented the more moderate faction of the Centre Party, but espoused an anti-immigration and nationalist ideology. Their claims of standing in the centre of the political landscape have thus been disputed by political scientists. The Centre Democrats did not gain enough votes for parliamentary representation in the 1986 general election, but Janmaat won back his seat after the following election in 1989. In 1994 he was joined by two additional representatives won by the party. The CD was subject to a ''cordon sanitaire'' by the other parties in Parliament, although some ...

Centre Democrats (Denmark)
The Centre Democrats ( da, Centrum-Demokraterne, CD) were a Danish political party. History The party was formed in 1973 by Erhard Jakobsen, a former MP and mayor of Gladsaxe, as a centrist splinter group from the Danish Social Democrats. It participated in both centre-right governments (1982–1988) and centre-left governments (1993–1996). In the 2001 election it lost its parliamentary representation, a severe setback for the party. In the 2005 election it got 33,635 votes (1% of votes nationwide). It also ran in several municipalities in the Danish municipal election in November 2005. It also ran in simultaneous elections to the new Regional Councils, except in Region Midtjylland where a local party official forgot to hand in the required number of voters' signatures before the deadline closed. On 26 January 2008 an extraordinary party conference decided to dissolve the party by 1 February 2008. Party leaders * 1973–1989: Erhard Jakobsen * 1989–2005: Mimi Jako ...

Canadian Forces Decoration
The Canadian Forces' Decoration (post-nominal letters "CD") is a Canadian award bestowed upon members of the Canadian Armed Forces who have completed twelve years of military service, with certain conditions. By convention, it is also given to the Governor General of Canada upon his or her appointment as viceroy, which includes the title of Commander-in-Chief in and over Canada. The decoration is awarded to all ranks, who must have a good record of conduct during the final eight years of claimed service. The first Governor General to receive the CD was Viscount Alexander of Tunis in 1951. The medal was initially awarded to all members of the Royal Family who served in the Canadian Forces, even without completion of twelve years of service; this has, however, not been automatic since 1953. Criteria The decoration is awarded to officers and non-commissioned members of the Regular and Reserve forces, including honorary appointments within the Canadian Armed Forces. However, time ...

Cluster Decay
Cluster decay, also named heavy particle radioactivity or heavy ion radioactivity, is a rare type of nuclear decay in which an atomic nucleus emits a small "cluster" of neutrons and protons, more than in an alpha particle, but less than a typical binary fission fragment. Ternary fission into three fragments also produces products in the cluster size. The loss of protons from the parent nucleus changes it to the nucleus of a different element, the daughter, with a mass number ''A''d = ''A'' − ''A''e and atomic number ''Z''d = ''Z'' − ''Z''e, where ''A''e = ''N''e + ''Z''e. For example: : → + This type of rare decay mode was observed in radioisotopes that decay predominantly by alpha emission, and it occurs only in a small percentage of the decays for all such isotopes. The branching ratio with respect to alpha decay is rather small (see the Table below). :B = T_a / T_c Ta and Tc are the half-lives of the parent nucleus relative to alpha decay and cluster radioactivity, ...

Drag Coefficient
In fluid dynamics, the drag coefficient (commonly denoted as: c_\mathrm, c_x or c_) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag coefficient is always associated with a particular surface area. The drag coefficient of any object comprises the effects of the two basic contributors to fluid dynamic drag: skin friction and form drag. The drag coefficient of a lifting airfoil or hydrofoil also includes the effects of lift-induced drag. The drag coefficient of a complete structure such as an aircraft also includes the effects of interference drag. Definition The drag coefficient c_\mathrm d is defined as c_\mathrm d = \dfrac where: * F_\mathrm d is the drag force, which is by definition the force component in the direction of the flow velocity; * ...

Photolithography
In integrated circuit manufacturing, photolithography or optical lithography is a general term used for techniques that use light to produce minutely patterned thin films of suitable materials over a substrate, such as a silicon wafer, to protect selected areas of it during subsequent etching, deposition, or implantation operations. Typically, ultraviolet light is used to transfer a geometric design from an optical mask to a light-sensitive chemical (photoresist) coated on the substrate. The photoresist either breaks down or hardens where it is exposed to light. The patterned film is then created by removing the softer parts of the coating with appropriate solvents. Conventional photoresists typically consists of three components: resin, sensitizer, and solvent. Photolithography processes can be classified according to the type of light used, such as ultraviolet, deep ultraviolet, extreme ultraviolet, or X-ray. The wavelength of light used determines the minimum feature si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
