Akerselva
The Akerselva or Akerselven () is a river which flows through Oslo, Norway. It starts at Maridalsvannet in Oslomarka, and traverses the boroughs of Nordre Aker, Sagene, Grünerløkka, central Oslo and Grønland, finally ending at Paulsenkaien and Oset in Bjørvika. The river is considered to be a part of the Nordmarkvassdraget, and has the Norwegian watercourse number 006.Z. The entire river is about long, and the difference in elevation between source and mouth is approximately . In the past, the river was utilized as a source of energy for local industry, and along the river there are many old industrial buildings. In 1964, a 500-meter-long tunnel was constructed to allow the river to flow under the track area at Oslo Central Station. The tunnel runs from Vaterlandsparken to the Oslo fjord near the Opera house. By the 1970s, the river was heavily contaminated after 150 years of industrial and sewage discharge. In the 1980s, a local initiative to limit emissions and ...

Maridalsvannet
Maridalsvannet () is a lake in Maridalen, Oslo, Norway. It is the largest lake in the municipality of Oslo, serving as its primary drinking water supply. The lake drains via the river Akerselva to the Oslofjord. The primary inflows are Skjærsjøelva and Dausjøelva. The Hammeren Hydroelectric Power Station exploits the fall from Skjærsjøen to Maridalsvannet. The shores of the lake and substantial areas of woods and fields around it are owned by the city of Oslo to protect the water supply. Some farms are still operated under city supervision, but others were closed down in the mid-20th century; their remains are marked by historical signs. Hiking, cycling, and cross-country ski trails run near the south side of the lake and connect to the system of trails in the forests that surround Oslo. They can be reached by a short walk from the Kjelsås trolley, bus, or train stations. Trails run alongside Akerselva from the Marridalsvannet dam to near the Oslofjord. The Gjøvik Lin ...

Aker, Norway
Aker was a former independent municipality in Akershus, Norway, that constitutes the vast majority of the territory of the modern city of Oslo. The name originally belonged to a farm which was located near the current Old Aker Church. The church in turn became the source of the name of the parish and later municipality as well as Akershus Fortress, the main fief and main county of Akershus which included most of Eastern Norway until 1919, the smaller county of Akershus, and numerous institutions within this area.

Other closely related fish in the same family include trout, Salvelinus, char, Thymallus, grayling, Freshwater whitefish, whitefish, lenok and Hucho, taimen, all coldwater fish of the subarctic and cooler temperate regions with some sporadic endorheic populations in Central Asia.

Fish Using A Fish Ladder In Akerselva, Oslo, Norway
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolution, evolve through the Paleozoic, ...

Froth
Foams are two-phase material systems where a gas is dispersed in a second, non-gaseous material, specifically, in which gas cells are enclosed by a distinct liquid or solid material. Note, this source focuses only on liquid foams. Note, this source also focuses on liquid foams. Foam "may contain more or less liquid r solidaccording to circumstances", although in the case of gas-liquid foams, the gas occupies most of the volume. In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas. Etymology The word derives from the medieval German and otherwise obsolete ''veim'', in reference to the "frothy head forming in the glass once the beer has been freshly poured" (cf. ''ausgefeimt''). Structure A foam is, in many cases, a multi-scale system. One scale is the bubble: material foams are typically disordered and have a variety of bubble sizes. At larger sizes, the study of idealized foams is closely linked to the mathemat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
