Bergslagen
Bergslagen is a historical, cultural, and linguistic region located north of Lake Mälaren in northern Svealand, Sweden, traditionally known as a mining district. In Bergslagen, the mining and metallurgic industries have been important since the Middle Ages although Malmfälten ("the Ore Fields"), the mining district of northernmost Sweden centered at the towns of Kiruna and Malmberget, has been of greater importance during the 20th century. Bergslagen is not precisely defined, but generally understood to cover part of the provinces of Västmanland, Dalarna (the southern part), and Värmland (the eastern part). Typical towns in the area include Lindesberg, Nora, Fagersta, Sala, Kristinehamn, Filipstad, Grythyttan, Ludvika and Hedemora. Also parts of northern Östergötland, around Finspång, as well as southern Närke can be included, then often referring to ''South Bergslagen''. A wider definition of the area can include parts of Gästrikland (Hofors) and Uppland (the fo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nordisk Familjebok
''Nordisk familjebok'' (, "Nordic Family Book") is a Swedish encyclopedia that was published in print from between 1876 and 1993, and that is now fully available in digital form via Project Runeberg at Linköping University. Despite their considerable age and relative obsolescence, the public domain editions of the encyclopedia remain important reference works in Finland, especially on Finnish Wikipedia. History First edition ''Nordisk familjebok'' began when Halmstad publisher hired an editor, linguist , in 1874 to publish a six-volume encyclopedia. Linder drew up a plan for the work, designed the editorial team and created a large circle of experts and literary figures, who submitted article proposals and wrote and reviewed them. Under Linder's direction, the articles were then edited to make them as formal, consistent and accurate as possible. Much attention was paid to Nordic subjects, mainly Swedish and Finnish, where sources and models were often lacking, so extensive ...

Nationalencyklopedin
''Nationalencyklopedin'' (; "The National Encyclopedia" in English), abbreviated NE, is a comprehensive contemporary Swedish-language encyclopedia, initiated by a favourable loan from the Government of Sweden of 17 million Swedish kronor in 1980, which was repaid by December 1990. The printed version consists of 20 volumes with 172,000 articles; the Internet version comprises 260,000 articles (as of June 2005). History The project was born in 1980, when a government committee suggested that negotiations be initiated with various publishers. This stage was finished in August 1985, when in Höganäs became the publisher responsible for the project. The project specifications were for a modern reference work based on a scientific paradigm incorporating gender and environmental issues. Pre-orders for the work were unprecedented; before the first volume was published in December 1989, 54,000 customers had ordered the encyclopedia. The last volume came out in 1996, with three suppl ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—most recently part of the Eastern Ro ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Blast Furnace
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. ''Blast'' refers to the combustion air being "forced" or supplied above atmospheric pressure. In a blast furnace, fuel ( coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls downward. The end products are usually molten metal and slag phases tapped from the bottom, and waste gases (flue gas) exiting from the top of the furnace. The downward flow of the ore along with the flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and chemical reaction process. In contrast, air furnaces (such as reverbera ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Glacial Erratic
A glacial erratic is glacially deposited rock differing from the type of rock native to the area in which it rests. Erratics, which take their name from the Latin word ' ("to wander"), are carried by glacial ice, often over distances of hundreds of kilometres. Erratics can range in size from pebbles to large boulders such as Big Rock () in Alberta. Geologists identify erratics by studying the rocks surrounding the position of the erratic and the composition of the erratic itself. Erratics are significant because: *They can be transported by glaciers, and they are thereby one of a series of indicators which mark the path of prehistoric glacier movement. Their lithographic origin can be traced to the parent bedrock, allowing for confirmation of the ice flow route. *They can be transported by ice rafting. This allows quantification of the extent of glacial flooding resulting from ice dam failure which release the waters stored in proglacial lakes such as Lake Missoula. Erratics ...

Kettle (landform)
A kettle (also known as a kettle lake, kettle hole, or pothole) is a depression/hole in an outwash plain formed by retreating glaciers or draining floodwaters. The kettles are formed as a result of blocks of dead ice left behind by retreating glaciers, which become surrounded by sediment deposited by meltwater streams as there is increased friction. The ice becomes buried in the sediment and when the ice melts, a depression is left called a kettle hole, creating a dimpled appearance on the outwash plain. Lakes often fill these kettles; these are called kettle hole lakes. Another source is the sudden drainage of an ice-dammed lake. When the block melts, the hole it leaves behind is a kettle. As the ice melts, ramparts can form around the edge of the kettle hole. The lakes that fill these holes are seldom more than deep and eventually fill with sediment. In acid conditions, a kettle bog may form but in alkaline conditions, it will be kettle peatland. Overview Kettles are fluviog ...

Lindesberg () is a locality and the seat of Lindesberg Municipality, Örebro County, Sweden with 9,672 inhabitants in 2017. History Lindesberg has centuries old history, being the center of an old mining district. The earliest known traces of a town are in the foundations of the 14th century stone church. That town was however known as Lindesås. It got its charter and current name in 1643, granted by Queen Christina, making it one of the now defunct Cities of Sweden.
