Svartediket
Svartediket is a lake in the city of Bergen in Vestland county, Norway. The lake lies immediately north of the mountain Ulriken, northeast of the Store Lungegårdsvannet bay. Historically, this lake was called ''Ålrekstadsvannet'', but in the late 19th century, a dam was built on the south end of the lake to create a reservoir for the city's drinking water. The lake is the main source of drinking water for the central parts of the city of Bergen. There is a pumping station and treatment facility build adjacent to the lake inside the mountain Ulriken. Drinking water is collected at a depth in Svartediket. Inside the water treatment plant, the water is filtered and irradiated with UV light to kill harmful microorganisms. After treatment, the clean drinking water is stored in a large water pool inside the mountain. This is the water that is pumped down to the city center for drinking water. In 2004, Bergen was hit by a ''Giardia lamblia'' epidemic An epidemic (from Gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vestland
Vestland is a county in Norway established on 1 January 2020. The county is located in Western Norway and it is centred around the city of Bergen, Norway's second largest city. The administrative centre of the county is the city of Bergen, where the executive and political leadership is based, but the County Governor is based in Hermansverk. The county is one of two counties in Norway that have Nynorsk as their official written language form (the others are neutral as to which form people use). Vestland was created in 2020 when the former counties of Hordaland and Sogn og Fjordane (with the exception of Hornindal municipality, which became part of Volda municipality in Møre og Romsdal county) were merged. History Vestland county is a newly created county, but it has been inhabited for centuries. The area was made up of many petty kingdoms under the Gulating during the Middle Ages. The northern part was the known as ''Firdafylke'' (now the Fjordane region; Nordfjord-Sunnfjord), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ulriken
Ulriken (or the older, ''Ålreken'') is the highest of the Seven Mountains ( no, De syv fjell) that surround the city of Bergen, Norway. It has a height of above sea level. Ulriken has an aerial tramway, Ulriksbanen, that can bring people to the top. At the top there is a TV tower, a restaurant, and free telescopes. There is a network of trails along Ulriken, which is a popular hike with several paths up ranging from steep to not so steep. History One of the slopes of Ulriken, known as Isdalen ("Ice Valley"), is also nicknamed "Death Valley", due to the area's history of suicides in the Middle Ages, and more recent hiking accidents. The valley became well known in 1970 when the remains of the mysterious Isdal Woman was discovered there. Another area of the mountain is called "Montana". Ulriksbanen Ulriksbanen is a passenger aerial tramway in Bergen, Norway. It connects the mountain Ulriken to the city, and is frequently used by tourists as well as locals. The tramway was ...

Store Lungegårdsvannet
Store Lungegårdsvannet is a bay located in the city and municipality of Bergen in Vestland county, Norway. The bay separates the city centre, located in the borough of Bergenhus, from the southern boroughs of the city, Årstad, Fana and Ytrebygda. The bay is situated at the end of the Puddefjorden. History The bay is named after the farm of ''Lungegården'', the estate of the Danish nobleman Vincens Lunge. In the Middle Ages, the bay was named ''Alrekstadvågen'', after the royal farm of '' Alrekstad''. Historically, the lake Lille Lungegårdsvannet was located just northwest of the bay, and it emptied into the bay. In the 1930s, the bay, and the area surrounding it, was an attractive recreation area for the inhabitants of the city, with boat harbours and beach A beach is a landform alongside a body of water which consists of loose particles.

Drinking Water
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure. For those who work in a hot climate, up to a day may be required. Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UV Light
Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack the energy to ionize atoms, it can cause chemical reactions and causes many substances to glow or fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules. Short-wave ultraviolet light damages DNA and sterilizes surfaces with which it comes into contact. For huma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giardia Lamblia
''Giardia duodenalis'', also known as ''Giardia intestinalis'' and ''Giardia lamblia'', is a flagellated parasitic microorganism of the genus '' Giardia'' that colonizes the small intestine, causing a diarrheal condition known as giardiasis. The parasite attaches to the epithelium by a ventral adhesive disc or sucker, and reproduces via binary fission. Giardiasis does not spread via the bloodstream, nor does it spread to other parts of the gastrointestinal tract, but remains confined to the lumen of the small intestine. Giardia has an outer membrane that makes it possible to retain life, even when outside of the host body, and which can make it tolerant to chlorine disinfection. ''Giardia'' trophozoites absorb their nutrients from the lumen, and are anaerobes. If the organism is split and stained, its characteristic pattern resembles the familiar "smiley face" symbol. Chief pathways of human infection include ingestion of untreated drinking water (which is the most common m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epidemic
An epidemic (from Ancient Greek, Greek ἐπί ''epi'' "upon or above" and δῆμος ''demos'' "people") is the rapid spread of disease to a large number of patients among a given population within an area in a short period of time. Epidemics of infectious diseases are generally caused by several factors including a significant change in the ecology of the areal population (e.g., increased stress maybe additional reason or increase in the density of a vector species), the introduction of an emerging pathogen to an areal population (by movement of pathogen or host) or an unexpected genetic change that is in the pathogen reservoir. Generally, epidemics concerns with the patterns of infectious disease spread. An epidemic may occur when host immunity to either an established pathogen or newly emerging novel pathogen is suddenly reduced below that found in the endemic equilibrium and the transmission threshold is exceeded. For example, in meningococcal infections, an attack rate in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
