Lutvann
Lutvann is a lake in the recreational area Østmarka in Oslo, Norway. It covers an area of 0.39 km², at 205 m elevation. Located just outside the capital city, it is a popular site for recreation, including swimming and fishing during summer, with brook trout in the lake. In the winter there are ski trails along and on the lake. The lake is also used by the Church of Jesus Christ of Latter-day Saints for baptism. In 2001 activists from the Youth of the Progress Party were charged for cutting down a tree in the preserved area in order to protest the fact that building in the area is prohibited. Romeriksporten As part of the construction of the Romerike Railway Tunnel during 1994–1999, there was a leak in the tunnel that caused up to 1,000 litres per minute to leak into the tunnel from lake above. Though the leakages had started in 1995, it was not until after they were discovered on February 3, 1997 sanctions were initiated by the Norwegian Water Resources and Energy Dire ...

Romerike Tunnel
The Romerike Tunnel ( no, Romeriksporten) is a railway tunnel in Norway between Oslo and Lillestrøm. It is the second longest railway tunnel in Norway after the Blix Tunnel opened in 2022, and forms the first section of the Gardermoen Line. It is double track and electrified, permitting speeds of . Construction started in 1994, with plans to open with the rest of the Gardermoen Line and Oslo Airport, Gardermoen on 8 October 1998. Due to serious leakage from Lutvann and several other lakes, it did not open until 22 August 1999. The leaks increased the cost of the tunnel from to NOK 1.8 billion. The main contractor was Scandinavian Rock Group. The tunnel was originally owned by NSB Gardermobanen, then the Norwegian National Rail Administration, and now owned by Bane NOR. The tunnel allows long-distance, regional and Flytoget Airport Express Trains to bypass the old Hoved Line, reducing journey times between Oslo and Lillestrøm from 29 to 12 minutes.

Østmarka
Østmarka is a forested area to the east of Oslo and part of the congregation of woodland areas known as Oslomarka. The area is situated within the municipalities Oslo, Lørenskog, Rælingen, Ski and Enebakk. Østmarka is delimited to the west by populated areas of Oslo, to the north of communities of Skårer, Lørenskog and Rælingen and to the east by the lake Øyeren, to the south-east lies Enebakk and to the south-west Sørmarka, another forested area. The change from Østmarka to Sørmarka takes place at the lake Langen. Østmarka is marked by its location on top of basement rock (more than 1 billion years old) containing easy-to-see folds that make up valleys and hills in the north-south direction. For this reason the terrain has a lot of hills, no matter where one goes. Along the upper marine border (about 210 meters) the ice of the last ice age has left large amounts of gravel and sand. Sand, Sandbakken ("Sandy Hill"), Sandbekken ("Sandy Creek") and Grusbakken ("Gravel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Norwegian Krone
The krone (, abbreviation: kr (also NKr for distinction); code: NOK), plural ''kroner'', is currency of the Kingdom of Norway (including Svalbard). Traditionally known as the Norwegian crown in English. It is nominally subdivided into 100 ''øre'', although the last coins denominated in øre were withdrawn in 2012. The krone was the thirteenth-most-traded currency in the world by value in April 2010, down three positions from 2007. The Norwegian krone is also informally accepted in many shops in Sweden and Finland that are close to the Norwegian border, and also in some shops in the Danish ferry ports of Hirtshals and Frederikshavn. Norwegians spent 14.1 billion NOK on border shopping in 2015 compared to 10.5 billion NOK spent in 2010. Border shopping is a fairly common practice amongst Norwegians, though it is seldom done on impulse. Money is spent mainly on food articles, alcohol, and tobacco, in that order, usually in bulk or large quantities. This is due to considerably ...

Acrylamide
Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH2=CHC(O)NH2. It is a white odorless solid, soluble in water and several organic solvents. From the chemistry perspective, acrylamide is a vinyl-substituted primary amide (CONH2). It is produced industrially mainly as a precursor to polyacrylamides, which find many uses as water-soluble thickeners and flocculation agents. Acrylamide forms in burnt areas of food, particularly starchy foods like potatoes, when cooked with high heat, above . Acrylamide is highly toxic, linked to cancer in animal testing though not likely to be carcinogenic for humans, but its main derivative polyacrylamide is nontoxic. The possibility that this innocuous polymer contains traces of its hazardous precursor has long attracted attention. Because acrylamide is volatile and hazardous, it is mainly handled as an aqueous solution. Production Acrylamide can be prepared by the hydration of acrylonitrile: :CH2=CHCN + H2O → ...

Polymer
A polymer (; Greek '' poly-'', "many" + ''-mer'', "part") is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compounds, produces unique physical properties including toughness, high elasticity, viscoelasticity, and a tendency to form amorphous and semicrystalline structures rather than crystals. The term "polymer" derives from the Greek word πολύς (''polus'', meaning "many, much") and μέρος (''meros'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhoca-Gil
{{unreferenced, date=December 2013 Rhoca-Gil is a type of industrial sealant produced by Rhône-Poulenc, used in the construction of tunnels to block the passage of groundwater into the tunnel. The sealant begins as a liquid, is then injected into cavities which need to be sealed, and polymerises, causing it to harden. Process Rhoca-Gil consists of two fluids, that are mixed, thinned out with water and then sprayed into cracks in the bedrock. One of the fluids contains acrylamide and methylolacrylamide. The mixed solution becomes a viscous fluid that penetrates cracks and holes in the rock, where the fluid reacts— polymerizes—to a tight plastic substance. When it is completely polymerized it is stable and will not exhaust any toxic compounds. Controversies In 1992 construction of the Hallandsås tunnel in Sweden began, with opening plans for 1995. Groundwater leaking into the tunnel was however a major problem, slowing the progress, and Rhoca-Gil was used. In 1997, fish ...

The municipality of Oslo had a population of in 2022, while the city's greater urban area had a population of in 2019, and the metropolitan area had an estimated population of in 2021. During the Viking Age the area was part of Viken. Oslo was founded as a city at the end of the Viking Age in 1040 under the name Ánslo, and established as a ''kaupstad'' or trading place in 1048 by Harald Hardrada. The city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 reduced its influence. After being destroyed by a fire in 1624, during the reign of King Christian IV, a new city was built closer to Akershus Fortress and named Christiania in honour of the king. It became a municipality ('' formannskapsdistrikt'') on 1 January 1838. The city fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
