Oak vs Donetsk

Informations

An oak is a tree or shrub in the genus Quercus (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably Lithocarpus (stone oaks), as well as in those of unrelated species such as Grevillea robusta (silky oaks) and the Casuarinaceae (she-oaks). The genus Quercus is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America contains the largest number of oak species, with approximately 90 occurring in the United States, while Mexico has 160 species of which 109 are endemic. The second greatest center of oak diversity is China, which contains approximately 100 species.

Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. Many deciduous species are marcescent, not dropping dead leaves until spring. In spring, a single oak tree produces both male flowers (in the form of catkins) and small female flowers, meaning that the trees are monoecious. The fruit is a nut called an acorn or oak nut borne in a cup-like structure known as a cupule; each acorn contains one seed (rarely two or three) and takes 6–18 months to mature, depending on their species. The acorns and leaves contain tannic acid, which helps to guard from fungi and insects. The live oaks are distinguished for being evergreen, but are not actually a distinct group and instead are dispersed across the genus.

Donetsk (UK: don-YETSK, US: də-N(Y)ETSK; Ukrainian: Донецьк [doˈnɛtsʲk] (listen); Russian: Донецк [dɐˈnʲetsk]), formerly known as Aleksandrovka, Hughesovka, Yuzovka, Stalin and Stalino (see also: cities' alternative names), is an industrial city in eastern Ukraine located on the Kalmius River in the disputed Donetsk region. While internationally recognized as in Ukraine, the city is under the de facto administration of the unrecognized Donetsk People's Republic, which claims it as its capital city. The population was estimated at 929,063 (2016 est.) in the city core, with over 2,000,000 in the metropolitan area (2011). According to the 2001 Ukrainian Census, Donetsk was the fifth-largest city in Ukraine.Administratively, Donetsk has been the centre of Donetsk Oblast, while historically, it is the unofficial capital and largest city of the larger economic and cultural Donets Basin (Donbass) region. Donetsk is adjacent to another major city, Makiivka, and along with other surrounding cities forms a major urban sprawl and conurbation in the region. Donetsk has been a major economic, industrial and scientific centre of Ukraine with a high concentration of heavy industries and a skilled workforce. The density of heavy industries (predominantly steel production, chemical industry, and coal mining) determined the city's challenging ecological situation. In 2012 a UN report ranked Donetsk among the world's fastest depopulating cities.The original settlement in the south of the European part of the Russian Empire was first mentioned as Aleksandrovka in 1779, during the reign of the Empress Catherine the Great.

In 1869 the Welsh businessman John Hughes founded a steel plant and several coal mines in the region, and the town was named Hughesovka or Yuzovka (Юзовка) in recognition of his role ("Yuz" being a Russian-language approximation of Hughes). During Soviet times, the city's steel industry expanded. In 1924 Yuzovka was renamed Stalin. In 1929 Stalin was renamed Stalino, and in 1932 the city became the centre of the Donetsk region. Renamed Donetsk in 1961, the city today remains a centre for coal mining and for the steel industry. Since April 2014 Donetsk and its surrounding areas have been one of the major sites of fighting in the ongoing Donbass War, as pro-Russian separatist forces battle against Ukrainian military forces for control of the city and surrounding areas. Throughout the war, the city of Donetsk has been administered by the pro-Russian separatist forces as the center of the Donetsk People's Republic (DPR), with outlying territories of the Donetsk region divided between the two sides. Donetsk International Airport became the epicenter of the war with almost a year-long battle leading to massive casualties among civilians and a total ruination of the northwestern neighborhoods of the city. As of July 2020, the DPR has full control of the city, with Ukrainian and DPR forces still engaging in combat outside of the city.
