Szeged
Szeged ( , ; see also #Etymology, other alternative names) is List of cities and towns of Hungary#Largest cities in Hungary, the third largest city of Hungary, the largest city and regional centre of the Southern Great Plain and the county seat of Csongrád-Csanád County, Csongrád-Csanád county. The University of Szeged is one of the most distinguished universities in Hungary. The Szeged Open Air (Theatre) Festival (first held in 1931) is one of the main attractions, held every summer and celebrated as the Day of the City on 21 May. Etymology It is possible that the name ''Szeged'' is a mutation (linguistics), mutated and truncated form of the final syllables of ''Partiscum (castra), Partiscum'', the name of a Roman colony founded in the 2nd century, on or near the site of modern Szeged. In Latin language contexts, has long been assumed to be synonymous with ''Szeged''. The Latin name is also the basis of the city's Ancient Greek, Greek name ''Partiskon''. However, ''Sz ...

Hungary
Hungary is a landlocked country in Central Europe. Spanning much of the Pannonian Basin, Carpathian Basin, it is bordered by Slovakia to the north, Ukraine to the northeast, Romania to the east and southeast, Serbia to the south, Croatia and Slovenia to the southwest, and Austria to the west. Hungary lies within the drainage basin of the Danube, Danube River and is dominated by great lowland plains. It has a population of 9.6 million, consisting mostly of ethnic Hungarians, Hungarians (Magyars) and a significant Romani people in Hungary, Romani minority. Hungarian language, Hungarian is the Languages of Hungary, official language, and among Languages of Europe, the few in Europe outside the Indo-European languages, Indo-European family.

Barium
Barium is a chemical element; it has symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal. Because of its high chemical reactivity, barium is never found in nature as a free element. The most common minerals of barium are barite ( barium sulfate, BaSO4) and witherite ( barium carbonate, BaCO3). The name ''barium'' originates from the alchemical derivative "baryta", from Greek (), meaning 'heavy'. ''Baric'' is the adjectival form of barium. Barium was identified as a new element in 1772, but not reduced to a metal until 1808 with the advent of electrolysis. Barium has few industrial applications. Historically, it was used as a getter for vacuum tubes and in oxide form as the emissive coating on indirectly heated cathodes. It is a component of YBCO (high-temperature superconductors) and electroceramics, and is added to steel and cast iron to reduce the size of carbon grains within the microstructure. Barium compounds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tungsram
Tungsram was a manufacturing company located in Hungary and known for their light bulbs and electronics. Established in Újpest (today part of Budapest, Hungary) in 1896, it initially produced telephones, wires and switchboards. The name "Tungsram" is a portmanteau of ''tungsten'' ( ) and ''wolfram'' ( ), the two common names of the metal used for making light bulb filaments. Before becoming nationalized by the Communist government in 1945, the company was the world's third largest manufacturer of light bulbs and radiotubes, after the American General Electric and RCA companies. History On 13 December 1904, Hungarian Sándor Just and Croatian Franjo Hanaman were granted Hungarian patent no. 34541 for the world's first tungsten filament bulb that lasted longer and produced brighter light than a carbon filament. The co-inventors licensed their patent to the company, which came to be named Tungsram after the eponymous tungsten incandescent bulbs, which are still called Tungsram ...

Tungsten
Tungsten (also called wolfram) is a chemical element; it has symbol W and atomic number 74. It is a metal found naturally on Earth almost exclusively in compounds with other elements. It was identified as a distinct element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternative name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements, melting at . It also has the highest boiling point, at . Its density is 19.254 g/cm3, comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work into metal. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many alloys ...
