Ernst-Thälmann-Park
Ernst-Thälmann-Park is a park in the centre of the Prenzlauer Berg district in Berlin. It was laid out in 1986 at the site of a former coal gas plant and named after the former Communist party leader Ernst Thälmann (1886-1944). The former plant built in 1874 was closed in 1981, the last gasometer was demolished in 1984. In honor of Berlin's 750-year jubilee the East German government drew up plans for an "inhabited park", including a memorial, a public pool, a planetarium, a school and a housing estate for 4,000 residents. The park was inaugurated on 16 April 1986, Thälmann's hundredth birthday. The former use of the area left an extensive contamination of soil and groundwater with cyanides, phenols and tar that after German reunification had to be cleared by excavation and bioremediation. Though there had been some discussion about the name, a majority of dwellers voted against a change in 1997. Today the park features public houses as well as art galleries and a small theatre ...

Prenzlauer Berg
Prenzlauer Berg () is a locality of Berlin, forming the southerly and most urban district of the borough of Pankow. From its founding in 1920 until 2001, Prenzlauer Berg was a district of Berlin in its own right. However, that year it was incorporated (along with the borough of Weißensee) into the greater district of Pankow. From the 1960s onward, Prenzlauer Berg was associated with proponents of East Germany's diverse counterculture including Christian activists, bohemians, state-independent artists, and the gay community. It was an important site for the peaceful revolution that brought down the Berlin Wall in 1989. In the 1990s the borough was also home to a vibrant squatting scene. It has since experienced rapid gentrification. Geography Prenzlauer Berg is a portion of the Pankow district in northeast Berlin. To the West and Southwest it borders Mitte, to the South Friedrichshain-Kreuzberg, to the East Lichtenberg, and to the North Weißensee and Pankow. Geologically, ...

Ernst Thälmann
Ernst Johannes Fritz Thälmann (; 16 April 1886 – 18 August 1944) was a German communist politician, and leader of the Communist Party of Germany (KPD) from 1925 to 1933. A committed Marxist-Leninist and Stalinist, Thälmann played a major role during the political instability of the Weimar Republic, especially in its final years, when the KPD explicitly sought to overthrow the liberal democracy of the republic. Under his leadership the KPD became intimately associated with the government of the Soviet Union and the policies of Joseph Stalin. The KPD under Thälmann's leadership regarded the Social Democratic Party (SPD) as its main adversary and the party adopted the position that the social democrats were "social fascists". Thälmann was also leader of the paramilitary ''Roter Frontkämpferbund'' (which was banned as extremist by the governing social democrats in 1929). In 1932 he established Antifaschistische Aktion, commonly shortened to " Antifa". He was arrested by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Planetarium
A planetarium ( planetariums or ''planetaria'') is a theatre built primarily for presenting educational and entertaining shows about astronomy and the night sky, or for training in celestial navigation. A dominant feature of most planetariums is the large dome-shaped projection screen onto which scenes of stars, planets, and other celestial objects can be made to appear and move realistically to simulate their motion. The projection can be created in various ways, such as a star ball, slide projector, video, fulldome projector systems, and lasers. Typical systems can be set to simulate the sky at any point in time, past or present, and often to depict the night sky as it would appear from any point of latitude on Earth. Planetaria range in size from the 37 meter dome in St. Petersburg, Russia (called “Planetarium No 1”) to three-meter inflatable portable domes where attendees sit on the floor. The largest planetarium in the Western Hemisphere is the Jennifer Chalsty Plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lev Kerbel
Lev Yefimovich Kerbel (russian: Лев Ефимович Кербель; – 14 August 2003) was a sculptor of Soviet realist works. Kerbel's creations included statues of Karl Marx, Vladimir Lenin, Yuri Gagarin, which were sent by Soviet Government as gifts to socialist and the Third World countries across the world. Kerbel was born to a Jewish family in the village of Semyonovka in Chernigov Governorate, Russian Republic (currently Semenivka, Chernihiv Oblast, Ukraine), on the day that the Winter Palace in Petrograd was stormed by the Bolsheviks. Lev's family moved to the Smolensk region, where he began sculpting as a child. He continued to sculpt and in 1934 he won an award from the Komsomol (Young Communist League) for a plaque of Lenin. During World War II, Kerbel helped build the defenses for the Battle of Moscow, then served in the Northern Fleet, gaining renown as a military artist. After the war, Kerbel's career took off with a wide range of commissions. In 1958 he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioremediation
Bioremediation broadly refers to any process wherein a biological system (typically bacteria, microalgae, fungi, and plants), living or dead, is employed for removing environmental pollutants from air, water, soil, flue gasses, industrial effluents etc., in natural or artificial settings. The natural ability of organisms to adsorb, accumulate, and degrade common and emerging pollutants has attracted the use of biological resources in treatment of contaminated environment. In comparison to conventional physicochemical treatment methods bioremediation may offer considerable advantages as it aims to be sustainable, eco-friendly, cheap, and scalable. Most bioremediation is inadvertent, involving native organisms. Research on bioremediation is heavily focused on stimulating the process by inoculation of a polluted site with organisms or supplying nutrients to promote the growth. In principle, bioremediation could be used to reduce the impact of byproducts created from anthropogenic acti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Reunification
German reunification (german: link=no, Deutsche Wiedervereinigung) was the process of re-establishing Germany as a united and fully sovereign state, which took place between 2 May 1989 and 15 March 1991. The day of 3 October 1990 when the German Reunification Treaty entered into force dissolving the German Democratic Republic (GDR; german: link=no, Deutsche Demokratische Republik, DDR, or East Germany) and integrating its recently re-established constituent federated states into the Federal Republic of Germany (FRG; german: link=no, Bundesrepublik Deutschland, BRD, or West Germany) to form present-day Germany, has been chosen as the customary ''German Unity Day'' () and has thereafter been celebrated each year from 1991 as a national holiday. East and West Berlin were united into a single city and eventually became the capital of reunited Germany. The East Germany's government led by the Socialist Unity Party of Germany (SED) (a communist party) started to falter on 2 May 1 ...

Phenols
In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (— O H) bonded directly to an aromatic hydrocarbon group. The simplest is phenol, . Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule. Phenols are both synthesized industrially and produced by plants and microorganisms. Properties Acidity Phenols are more acidic than typical alcohols. The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their pKa is usually between 10 and 12). Deprotonation of a phenol forms a corresponding negative phenolate ion or phenoxide ion, and the corresponding salts are called phenolates or phenoxides (aryloxides according to the IUPAC Gold Book). Condensation with aldehydes and ketones Phenols are susceptible to Electrophilic aromatic substitutions. Condensation with formald ...

Cyanide
Cyanide is a naturally occurring, rapidly acting, toxic chemical that can exist in many different forms. In chemistry, a cyanide () is a chemical compound that contains a functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. In inorganic cyanides, the cyanide group is present as the anion . Soluble salts such as sodium cyanide (NaCN) and potassium cyanide (KCN) are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts. Organic cyanides are usually called nitriles. In nitriles, the group is linked by a covalent bond to carbon. For example, in acetonitrile (), the cyanide group is bonded to methyl (). Although nitriles generally do not release cyanide ions, the cyanohydrins do and are thus rather toxic. Bonding The cyanide ion is isoelectronic with carbon monoxide a ...

Gas Holder
A gas holder or gasholder, also known as a gasometer, is a large container in which natural gas or town gas is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of stored gas, with pressure coming from the weight of a movable cap. Typical volumes for large gas holders are about , with diameter structures. Gas holders now tend to be used for balancing purposes to ensure that gas pipes can be operated within a safe range of pressures, rather than for actually storing gas for later use. Etymology Antoine Lavoisier devised the first gas holder, which he called a ''gazomètre'', to assist his work in pneumatic chemistry. It enabled him to weigh the gas in a pneumatic trough with the precision he required. He published his ''Traité Élémentaire de Chimie'' in 1789. James Watt Junior collaborated with Thomas Beddoes in constructing the pneumatic apparatus, a shortlived piece of medical equipment that incorporated a ''gazo ...

East Germany
East Germany, officially the German Democratic Republic (GDR; german: Deutsche Demokratische Republik, , DDR, ), was a country that existed from its creation on 7 October 1949 until its dissolution on 3 October 1990. In these years the state was a part of the Eastern Bloc in the Cold War. Commonly described as a communist state, it described itself as a socialist "workers' and peasants' state".Patrick Major, Jonathan Osmond, ''The Workers' and Peasants' State: Communism and Society in East Germany Under Ulbricht 1945–71'', Manchester University Press, 2002, Its territory was administered and occupied by Soviet forces following the end of World War II—the Soviet occupation zone of the Potsdam Agreement, bounded on the east by the Oder–Neisse line. The Soviet zone surrounded West Berlin but did not include it and West Berlin remained outside the jurisdiction of the GDR. Most scholars and academics describe the GDR as a totalitarian dictatorship. The GDR was establish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
