Compact Disc
The compact disc (CD) is a Digital media, digital optical disc data storage format co-developed by Philips and Sony to store and play digital audio recordings. It employs the Compact Disc Digital Audio (CD-DA) standard and was capable of holding of uncompressed stereo audio. First released in Japan in October 1982, the CD was the second optical disc format to reach the market, following the larger LaserDisc (LD). In later years, the technology was adapted for computer data storage as CD-ROM and subsequently expanded into various writable and multimedia formats. , over 200 billion CDs (including audio CDs, CD-ROMs, and CD-Rs) had been sold worldwide. Standard CDs have a diameter of and typically hold up to 74 minutes of audio or approximately of data. This was later regularly extended to 80 minutes or by reducing the spacing between data tracks, with some discs unofficially reaching up to 99 minutes or which falls outside established specifications. Smaller variants, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cadmium
Cadmium is a chemical element; it has chemical symbol, symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12 element, group 12, zinc and mercury (element), 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 group 3 element, groups 3 through group 11 element, 11. Cadmium and its Congener (chemistry), 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 Friedrich Stromeyer, Stromeyer and Karl Samuel Leberecht Hermann, Hermann, both in Germany, as an impurity in zinc carbonate. Cadmium occurs as a minor component in most zinc ores and i ... [...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 or civil protection is an effort to protect the citizens of a state (generally non-combatants) from human-made and natural disasters. It uses the principles of emergency management: Risk management, 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 strategic bombing, 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 plan, co ...

Christian Democracy
Christian democracy is an ideology inspired by Christian social teaching to respond to the challenges of contemporary society and politics. Christian democracy has drawn mainly from Catholic social teaching and neo-scholasticism, as well as the Neo-Calvinist tradition within Christianity; it later gained ground with Lutherans and Pentecostals, among other denominational traditions of Christianity in various parts of the world. During the nineteenth century, its principal concerns were to reconcile Catholicism with democracy, to answer the " social question" surrounding capitalism and the working class, and to resolve the tensions between church and state. In the twentieth century, Christian democrats led postwar Western and Southern Europe in building modern welfare states and constructing the European Union. Furthermore; in the late twentieth and early twenty-first century, Christian democracy has gained support in Eastern Europe among former communist states sufferi ...

Centro Democratico
Democratic Centre (, CD) is a centrism, centrist, Christian leftist and Social liberalism, social-liberal political party in Italy. Most of its members, including its leader Bruno Tabacci, are former Christian Democracy (Italy), Christian Democrats. Since its beginnings, the CD has been also part of the Centre-left coalition (Italy), centre-left coalition, centred around the Democratic Party (Italy), Democratic Party (PD). The CD, along with the Italian Radicals and Forza Europa (2017), Forza Europa, was a founding member of More Europe (+E), a Liberalism, 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.

Centre Democrats (Netherlands)
The Centre Democrats (, CD) was a List of political parties in the Netherlands, political party in the Netherlands. Founded in 1984 by members who split out from the Centre Party (Netherlands), 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 Opposition to immigration, anti-immigration and Nationalism, 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 Dutch general election, 1986 general election, but Janmaat won back his seat after the following 1989 Dutch general election, election in 1989. In 1994 Dutch general el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centre Democrats (Denmark)
The Centre Democrats (, 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 Jakobsen * 2005–2007 ...

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 their appointment, 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.

Cluster Decay
Cluster decay, also named heavy particle radioactivity, heavy ion radioactivity or heavy cluster decay," 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. Description The loss of protons from the parent nucleus changes it to the nucleus of a different element, the daughter, with a mass number ''Ad'' = ''A'' − ''Ae'' and atomic number ''Zd'' = ''Z'' − ''Ze'', where ''Ae'' = ''Ne'' + ''Ze''. For example: : → + According to "Ronen's golden rule" of cluster decay, the emitted nucleus tends to be one with a high binding energy per nucleon, and especially one with a magic number of nucleons. 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 al ...

Photolithography
Photolithography (also known as optical lithography) is a process used in the manufacturing of integrated circuits. It involves using light to transfer a pattern onto a substrate, typically a silicon wafer. The process begins with a photosensitive material, called a photoresist, being applied to the substrate. A photomask that contains the desired pattern is then placed over the photoresist. Light is shone through the photomask, exposing the photoresist in certain areas. The exposed areas undergo a chemical change, making them either soluble or insoluble in a developer solution. After development, the pattern is transferred onto the substrate through etching, chemical vapor deposition, or ion implantation processes. Ultraviolet, Ultraviolet (UV) light is typically used. Photolithography processes can be classified according to the type of light used, including ultraviolet lithography, deep ultraviolet lithography, extreme ultraviolet lithography, extreme ultraviolet lithography ...
