Allmennaksjeselskap
''Aksjeselskap'' is the Norwegian term for a stock-based company. It is usually abbreviated AS, historically often written as A/S. An AS is always a limited company, i.e. the owners cannot be held liable for any debt beyond the stock capital. Public companies are called Allmennaksjeselskap (ASA), while companies without limited liability are called ''Ansvarlig selskap'' (ANS). All AS companies must have a stock capital of at least NOK 30,000. In addition, they must have a board of directors, depending on the size of turnover, balance sheet total or number of employees, an auditor. They may appoint a managing director (MD) or chief executive (CEO). If the company has assets exceeding NOK 3 million, the board must have at least three members and cannot be chaired by the MD/CEO. Practically all Norwegian companies have a fiscal year from January to December, but some foreign subsidiaries may have a different fiscal year, as is allowed, to match the parent corporation. The ASA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...

Tinn
Tinn is a municipality in Telemark in the county of Vestfold og Telemark in Norway. It is part of the traditional regions of Upper Telemark and Øst-Telemark. The administrative centre of the municipality is the town of Rjukan. The parish of ''Tin(d)'' was established as a municipality on 1 January 1838 (see formannskapsdistrikt). The area of Hovin was separated from the municipality of Tinn in 1860, but it was merged back into the municipality of Tinn on 1 January 1964. Krossobanen is the oldest aerial tramway in Northern Europe. It was built in 1928 as a gift from Norsk Hydro. There is a museum and Hardangervidda National Park center at the lake Møsvatn close to Tinn. General information Name The Old Norse form of the name was ''Tinnr''.

Rjukan
Rjukan () is a town and the administrative centre of Tinn municipality in Telemark, Norway. It is situated in Vestfjorddalen, between Møsvatn and Lake Tinn, and got its name after Rjukan Falls west of the town. The Tinn municipality council granted township status for Rjukan in 1996. The town has 3,386 inhabitants (January 2007). History Rjukan was formerly a significant industrial centre in Telemark, and the town was established between 1905 and 1916, when Norsk Hydro started saltpetre (fertilizer) production there. Rjukan was chosen because Rjukan Falls, a 104-metre waterfall, provided easy means of generating large quantities of electricity. The man with the idea to use the Rjukan falls was Sam Eyde, the founder of Hydro. It is estimated that he, together with A/S Rjukanfoss (later Norsk Hydro), used about two times the national budget of Norway to build the Rjukan power station as well as much of the surrounding town. Between 1907 and 1911, Norsk Hydro built what was at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Notodden
Notodden () is a city and municipality in Vestfold og Telemark county, Norway. It is part of the traditional region of Øst-Telemark. The administrative centre of the municipality is the city of Notodden. Notodden was separated from the municipality of Heddal in 1913 to become a separate city and municipality. On 1 January 1964, the rural municipalities of Heddal and Gransherad were merged into Notodden to form a new enlarged municipality. Notodden is on the shore of Heddalsvatnet lake, and the Tinn River runs through the town into the lake.

Norsk Hydro Rjukan
Norsk Hydro Rjukan is an industrial facility operated by Norsk Hydro at Rjukan in Tinn, Norway, from 1911 to 1991. The plant manufactured chemicals related to the production of fertilizer, initially potassium nitrate from arc-produced nitric acid and later ammonia, hydrogen, and heavy water. The location was chosen for its vicinity to hydroelectric power plants built in the Måna river. 30 million tonnes of products, equivalent of 1.5 million wagon loads, were produced in Rjukan. After the closing, parts of the plants and the railway have been preserved. History Background The Telemark power-based industry adventure started in 1902 when Sam Eyde, along with Norwegian and Swedish investors, bought Rjukan Falls—establishing A/S Rjukanfos on 30 April 1903. The same year, on 13 February, Eyde and Kristian Birkeland had met and started working on refining the electric arc to produce an electric flame; allowing Eyde to complete his process of converting air and electricity into fer ...

Rjukan Falls
Rjukan Falls ( no, Rjukanfossen) is a waterfall of 104 metres in the western part of the Westfjord valley in Tinn, a municipality in the county of Vestfold og Telemark, Norway, west of the industrial town Rjukan. The waterfall is a part of the Måne river, earlier a major tourist attraction, being one of the first floodlighted waterfalls by electricity produced by the same waterfall. In 1905 Rjukan Falls was built out to produce hydro electrical power for the saltpetre production when Norsk Hydro was established. , retrieved 2 April 2013 The name The name ( |
Birkeland–Eyde Process
The Birkeland–Eyde process was one of the competing industrial processes in the beginning of nitrogen-based fertilizer production. It is a multi-step nitrogen fixation reaction that uses electrical arcs to react atmospheric nitrogen (N2) with oxygen (O2), ultimately producing nitric acid (HNO3) with water. The resultant nitric acid was then used as a source of nitrate (NO3−) in the reaction HNO3 + H2O -> H3O+ + NO3- which may take place in the presence of water or another proton acceptor. It was developed by Norwegian industrialist and scientist Kristian Birkeland along with his business partner Sam Eyde in 1903, based on a method used by Henry Cavendish in 1784. A factory based on the process was built in Rjukan and Notodden in Norway, combined with the building of large hydroelectric power facilities. The Birkeland–Eyde process is relatively inefficient in terms of energy consumption. Therefore, in the 1910s and 1920s, it was gradually replaced in Norway by a combinatio ...

Kristian Birkeland
Kristian Olaf Bernhard Birkeland (13 December 1867 – 15 June 1917) was a Norwegian scientist. He is best remembered for his theories of atmospheric electric currents that elucidated the nature of the aurora borealis. In order to fund his research on the aurorae, he invented the electromagnetic cannon and the Birkeland–Eyde process of fixing nitrogen from the air. Birkeland was nominated for the Nobel Prize seven times. Life and death Birkeland was born in Christiania (Oslo today) to Reinart Birkeland and Ingeborg (née Ege) and wrote his first scientific paper at the age of 18. Birkeland married Ida Charlotte Hammer in May 1905. They had no children and, due to Birkeland's preoccupation with his work, they divorced in 1911. Suffering from severe paranoia due to his use of barbital as a sleeping aid, he died under mysterious circumstances in his room in the Hotel Seiyoken in Tokyo while visiting colleagues at the University of Tokyo. A post-mortem revealed that Birkeland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrogen
Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N2, a colorless and odorless diatomic gas. N2 forms about 78% of Earth's atmosphere, making it the most abundant uncombined element. Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins), in the nucleic acids ( DNA and RNA) and in the energy transfer molecule adenosine triphosphate. The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. The nitrogen cycle describes the movement of the element from the air, into the biosphere and organic compounds, then back into the atmosphere. Many indus ...

Fertilizer
A fertilizer (American English) or fertiliser (British English; see spelling differences) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment or hand-tool methods. Historically fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations and byproducts of human-nature industries (i.e. fish processing waste, or bloodmeal fro ...
