Velvet Revolution
The Velvet Revolution ( cs, Sametová revoluce) or Gentle Revolution ( sk, Nežná revolúcia) was a non-violent transition of power in what was then Czechoslovakia, occurring from 17 November to 28 November 1989. Popular demonstrations against the one-party government of the Communist Party of Czechoslovakia included students and older dissidents. The result was the end of Czechoslovak Socialist Republic, 41 years of one-party rule in Czechoslovakia, and the subsequent dismantling of the command economy and conversion to a parliamentary republic. On 17 November 1989 (International Students' Day), riot police suppressed a Student activism, student demonstration in Prague. The event marked the 50th anniversary of a violently suppressed demonstration against the Nazi storming of Prague University in 1939 where 1,200 students were arrested and 9 killed (see International Students' Day#Origin, Origin of International Students' Day). The 1989 event sparked a series of demonstrations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mandatory Retirement
Mandatory retirement also known as forced retirement, enforced retirement or compulsory retirement, is the set age at which people who hold certain jobs or offices are required by industry custom or by law to leave their employment, or retire. As of 2017, as reported by the Organisation for Economic Co-operation and Development (OECD), only three European member states (UK, Denmark and Poland) and four OECD countries (Canada, Australia, New Zealand, United States) had laws banning mandatory retirement. Rationale Typically, mandatory retirement is justified by the argument that certain occupations are either too dangerous (military personnel) or require high levels of physical and mental skill ( air traffic controllers, airline pilots). Most rely on the notion that a worker's productivity declines significantly after age 70, and the mandatory retirement is the employer's way to avoid reduced productivity. However, since the age at which retirement is mandated is often somewhat ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Full Professor
Professor (commonly abbreviated as Prof.) is an academic rank at universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital letter nearly always refers to a full professo ...

Nitrates
Nitrate is a polyatomic ion with the chemical formula . Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate. Structure The ion is the conjugate base of nitric acid, consisting of one central nitrogen atom surrounded by three identically bonded oxygen atoms in a trigonal planar arrangement. The nitrate ion carries a formal charge of −1. This charge results from a combination formal charge in which each of the three oxygens carries a − charge, whereas the nitrogen carries a +1 charge, all these adding up to formal charge of the polyatomic nitrate ion. This arrangement is commonly used as an example of resonance. Like the isoelectronic carbonate ion, the nitrate ion can be represented by resonance structures: Dietary nitrate A rich source of inorganic nitrate in the human diets come from leafy gre ...
