Aquarium filters are critical components of both freshwater and marine aquaria.Aquarium filters remove physical and soluble chemical waste products from aquaria, simplifying maintenance. Furthermore, aquarium filters are necessary to support life as aquaria are relatively small, closed volumes of water compared to the natural environment of most fish.
Overview
Animals, typically fish, kept in fish tanks produce waste from excrement and respiration. Another source of waste is uneaten food or plants and fish which have died. These waste products collect in the tanks and contaminate the water. As the degree of contamination rises, the risk to the health of the aquaria increases and removal of the contamination becomes critical. Filtration is a common method used for maintenance of healthy aquaria.
Biological filtration and the nitrogen cycle
Proper management of the nitrogen cycle is a vital element of a successful aquarium. Excretia and other decomposing organic matter produce ammonia which is highly toxic to fish. Bacterial processes oxidize this ammonia into the slightly less toxic nitrites, and these are in turn oxidized to form the much less toxic nitrates. In the natural environment these nitrates are subsequently taken up by plants as fertilizer and this does indeed happen to some extent in an aquarium planted with real plants.
Filter is an Americantelevision series on the G4 cable television channel which follows a countdown format. It was canceled in December 2005, resurrected in a re-formatted form, and then once again was canceled in August 2006. It was airing as an interstitial program during commercial breaks prior to May 2012. The show allows registers users (or viewers) to vote in Top Ten lists.
History
Filter was one of the 13 original series to debut with G4. The focus of the show was video games, and each episode covered a different genre, such as sports or role-playing video games. Each week a new theme was chosen and viewers chose the top ten to be featured on the show. The top two games would be put in a Filter Face-off, where the winner was revealed. Shows included the top ten Final Fantasy games, worst games of all time, and all-time top-ten platformers.
After the purchase of TechTV, Filter was revamped to include more pop culture lists such as theatrical and DVDmovie releases, music concerts, and consumer technology. The segment "Tech Toss-up" was added to cover new gadgets such as cellphones and MP3 players. A segment called "Net to Know" showcased correspondent John Walsh's top three websites of the week.
Filter is an American industrial rock group formed in 1993 in Cleveland by singer Richard Patrick and guitarist/programmer Brian Liesegang. The band was formed after Patrick desired to start his own band after leaving Nine Inch Nails as their touring guitarist. Their debut album, Short Bus, was released in 1995, and ended up going platinum, selling over one million copies, largely due to the success of the band's single "Hey Man Nice Shot." After the album, the band would go through the first of many line-up changes, leaving Patrick as the only consistent member across all music releases.
Patrick released the band's follow up album, Title of Record, which also went platinum, off the success of the song "Take a Picture", in 1999, and a third album, The Amalgamut, in 2002, before checking into rehab after years of heavy alcohol and drug abuse. The band went into hiatus while Patrick went to rehab, and then formed a new band, Army of Anyone, which released one self-title album. Filter reformed in 2008 to release Anthems for the Damned, and then The Trouble with Angels in 2010, with Patrick and a revolving door of other musicians. Filter's sixth and most recent studio album, The Sun Comes Out Tonight, was released in 2013. A seventh studio album is scheduled for release in 2016.
In signal processing, a filter is a device or process that removes from a signal some unwanted component or feature. Filtering is a class of signal processing, the defining feature of filters being the complete or partial suppression of some aspect of the signal. Most often, this means removing some frequencies and not others in order to suppress interfering signals and reduce background noise. However, filters do not exclusively act in the frequency domain; especially in the field of image processing many other targets for filtering exist. Correlations can be removed for certain frequency components and not for others without having to act in the frequency domain.
There are many different bases of classifying filters and these overlap in many different ways; there is no simple hierarchical classification. Filters may be:
time-invariant or time-variant, also known as shift invariance. If the filter operates in a spatial domain then the characterization is space invariance.
Aquarium is the debut studio album by Danish-Norwegian band Aqua. The album was released in Scandinavia on 26 March 1997 and in the United States on 9 September 1997. Although the group had been together for three years under their original name Joyspeed, their only release under that name was a single called "Itzy Bitsy Spider". The album is best known for including the successful singles "Barbie Girl", "Doctor Jones" and "Turn Back Time", the first of those being a huge hit across the globe. (The album was preceded by the two singles "Roses Are Red" and "My Oh My", with the latter re-released in 1998.)
The album's third single, "Barbie Girl" brought the group to international attention after reaching number one in both Denmark and Norway, as well as across Europe and in Australia and New Zealand. It would later peak at number 7 in the US. Its success helped the album reach number one in both the group's home countries, and make the top 10 in the UK and US. While not selling as highly "Barbie Girl", the album's fourth single "Doctor Jones" was released in late 1997/early 1998 and became a number one in Denmark, Norway, Australia and the UK. "Turn Back Time" would later give the group their third consecutive number one single in the UK, despite only reaching number 16 in Denmark. The final single, "Good Morning Sunshine" failed to chart highly and was only released in select regions like the earlier "Lollipop (Candyman)", the group's only other song to chart in the US. The album has sold 14 million copies worldwide.
Aquarium or Akvarium (Russian:Аква́риум) is a Russian rock group formed in Leningrad (now Saint Petersburg, Russia) in 1972. The band had many member changes over its 40-year history, and at the end the only remaining original member was lead singer and founder Boris Grebenshikov. Former band members have included Anatoly Gunitsky, Dyusha Romanov, Sergey Kuryokhin, and Vsevolod Gakkel.
The popular story behind the name "Aquarium" is that it was inspired by the Budapest street Leningrad pub "The Aquarium" and suggested by one of the band members. However, Grebenshikov has given differing stories in interviews, suggesting alternately that it came through band word association sessions or was inspired a glass aquarium-like building.
