Emil Racoviță
Emil Gheorghe Racoviță (; 15 November 1868 – 19 November 1947) was a Romanian biologist, zoologist, speleologist, and Antarctic explorer. Together with Grigore Antipa, he was one of the most noted promoters of natural sciences in Romania. Racoviță was the first Romanian to have gone on a scientific research expedition to the Antarctic. He was an influential professor, scholar and researcher, and served as President of the Romanian Academy from 1926 to 1929. Early life Born in Iași, he grew up on a family estate, in Șurănești, Vaslui County, he started his education in Iași, where he had Ion Creangă as a teacher, and continued his secondary education at the ''Institutele Unite'', a private high school for boys in Iași, taking his baccalauréat in 1886. He then studied law at the University of Paris, obtaining a law degree in 1889. But he did not pursue a law career, instead turning to the natural sciences. His mentor was zoologist and biologist Henri de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iași
Iași ( , , ; also known by other #Etymology and names, alternative names), also referred to mostly historically as Jassy ( , ), is the Cities in Romania, third largest city in Romania and the seat of Iași County. Located in the historical region of Western Moldavia, Moldavia, it has traditionally been one of the leading centres of Romanian social, cultural, academic and artistic life. The city was the capital of the Principality of Moldavia from 1564 to 1859, then of the United Principalities from 1859 to 1862, and the capital of Kingdom of Romania, Romania from 1916 to 1918. Known as the Cultural Capital of Romania Iași is a symbol of Romanian history. Historian Nicolae Iorga stated that "there should be no Romanian who does not know of it". Still referred to as "The Moldavian Capital", Iași is the main economic and business centre of Romania's Moldavian region. In December 2018, Iași was officially declared the Historical Capital of Romania. At the 2021 Romanian censu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speleologist
Speleology () is the scientific study of caves and other karst features, as well as their composition, structure, physical properties, history, ecology, and the processes by which they form (speleogenesis) and change over time (speleomorphology). The term ''speleology'' is also sometimes applied to the recreational activity of exploring caves, but this is more properly known as ''caving'', ''potholing'' (British English), or ''spelunking'' (United States and Canadian English). Speleology and caving are often connected, as the physical skills required for ''in situ'' study are the same. Speleology is a cross-disciplinary field that combines the knowledge of chemistry, biology, geology, physics, meteorology, and cartography to develop portraits of caves as complex, evolving systems. History Before modern speleology developed, John Beaumont wrote detailed descriptions of some Mendip caves in the 1680s. The term speleology was coined by Émile Rivière in 1890. Prior to the ...

Second International
The Second International, also called the Socialist International, was a political international of Labour movement, socialist and labour parties and Trade union, trade unions which existed from 1889 to 1916. It included representatives from most of Europe's major working-class organizations, though was dominated by the Social Democratic Party of Germany. The international continued the work of the International Workingmen's Association, First International, which had dissolved in 1876. It was ideologically dominated by Marxism, although other viewpoints were represented, notably anarchism before the anarchists were expelled in 1896. Leading theorists within the Second International included Friedrich Engels, Karl Kautsky, and Georgi Plekhanov, as well as Vladimir Lenin and Rosa Luxemburg. The Second International was primarily concerned with developing and coordinating strategy and tactics, and with establishing common policies for its member parties. Congress meetings were hel ...

Socialism
Socialism is an economic ideology, economic and political philosophy encompassing diverse Economic system, economic and social systems characterised by social ownership of the means of production, as opposed to private ownership. It describes the Economic ideology, economic, Political philosophy, political, and Social theory, social theories and Political movement, movements associated with the implementation of such systems. Social ownership can take various forms, including State ownership, public, Community ownership, community, Collective ownership, collective, cooperative, or Employee stock ownership, employee.: "Just as private ownership defines capitalism, social ownership defines socialism. The essential characteristic of socialism in theory is that it destroys social hierarchies, and therefore leads to a politically and economically egalitarian society. Two closely related consequences follow. First, every individual is entitled to an equal ownership share that earns an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polychaete
Polychaeta () is a paraphyletic class of generally marine Annelid, annelid worms, common name, commonly called bristle worms or polychaetes (). Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. More than 10,000 species are described in this class. Common representatives include the lugworm (''Arenicola marina'') and the Alitta virens, sandworm or Alitta succinea, clam worm ''Alitta''. Polychaetes as a class are robust and widespread, with species that live in the coldest ocean temperatures of the abyssal plain, to forms which tolerate the extremely high temperatures near hydrothermal vents. Polychaetes occur throughout the Earth's oceans at all depths, from forms that live as plankton near the surface, to a 2- to 3-cm specimen (still unclassified) observed by the robot ocean probe Nereus (underwater vehicle), ''Nereus'' at the bottom of the Challenger Deep, the deepest known spot in the Earth's ...

Encephalon
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as vision, hearing, and olfaction. Being the most specialized organ, it is responsible for receiving information from the sensory nervous system, processing that information (thought, cognition, and intelligence) and the coordination of motor control (muscle activity and endocrine system). While invertebrate brains arise from paired segmental ganglia (each of which is only responsible for the respective body segment) of the ventral nerve cord, vertebrate brains develop axially from the midline dorsal nerve cord as a vesicular enlargement at the rostral end of the neural tube, with centralized control over all body segments. All vertebrate brains can be embryonically divided into three parts: the forebrain (prosencephalon, subdivided i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
