Purified water

Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use. Distilled water has been the most common form of purified water, but, in recent years, water is more frequently purified by other processes including capacitive deionization, reverse osmosis, carbon filtering, microfiltration, ultrafiltration, ultraviolet oxidation, or electrodeionization. Combinations of a number of these processes have come into use to produce water of such high purity that its trace contaminants are measured in parts per billion (ppb) or parts per trillion (ppt). Purified water has many uses, largely in the production of medications, in science and engineering laboratories and industries, and is produced in a range of purities. It can be produced on site for immediate use or purchased in containers. Purified water in colloquial English can also refer to water which has been treated ("rendered potable") to neutralize, but not necessarily remove contaminants considered harmful to humans or animals.

Aria (manga)

Aria (アリア) is a utopian science fantasy manga by Kozue Amano. The series was originally titled Aqua (アクア, Akua) when it was published by Enix in the magazine Monthly Stencil, being retitled when it moved to Mag Garden's magazine Comic Blade.Aqua was serialized in Stencil from 2001 to 2002 and collected in two tankōbon volumes. Aria was serialized in Comic Blade from November 2002 to April 2008 and collected in twelve volumes. The series has been adapted as an anime television series, with a first season broadcast in 2005, a second season in 2006, an OVA released September 2007, and a third season in 2008 that ended around the same time as the manga serialization.

ADV Manga released English translations of the first three volumes of Aria in 2004, before dropping the license. Tokyopop then acquired the English-language rights to Aqua as well as Aria. Tokyopop released the two volumes of Aqua on October 2007 and February 2008, and six volumes of Aria between January 2008 and December 2010. The anime is licensed in North America by The Right Stuf International, which released all three seasons a box sets under its Nozomi Entertainment imprint between 30 September 2008 and 2 March 2010.

Aqua (band)

Aqua is a Danish eurodance group, best known for their 1997 breakthrough single "Barbie Girl". The group formed in 1989 and achieved huge success around the globe in the late 1990s and early 2000s. The group released three albums: Aquarium in 1997, Aquarius in 2000 and Megalomania in 2011. The group sold an estimated 33 million albums and singles, making them the most successful Danish band ever.

In their prime, Aqua's singles managed to chart top ten in a number of countries where European pop acts would not normally succeed, including the United States, Canada, Australia, and Japan. The group managed to top the UK Singles Chart with their first three singles. The group also caused controversy with the double entendres in their "Barbie Girl" single, with the Barbie doll makers Mattel filing a lawsuit against the group. The lawsuit was finally dismissed by a judge in 2002, who ruled "The parties are advised to chill."

The band's members are vocalists Lene Nystrøm and René Dif, keyboardist Søren Rasted, and guitarist Claus Norreen. During their split, Nystrøm, Dif and Rasted all achieved solo chart success, and Norreen continued in the music industry remixing other artists' material.

Sphere

A sphere (from Greek σφαῖρα — sphaira, "globe, ball") is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball, (viz., analogous to a circular object in two dimensions). Like a circle, which geometrically is a two-dimensional object, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point, but in three-dimensional space. This distance r is the radius of the ball, and the given point is the center of the mathematical ball. The longest straight line through the ball, connecting two points of the sphere, passes through the center and its length is thus twice the radius; it is a diameter of the ball.

While outside mathematics the terms "sphere" and "ball" are sometimes used interchangeably, in mathematics a distinction is made between the sphere (a two-dimensional closed surface embedded in three-dimensional Euclidean space) and the ball (a three-dimensional shape that includes the sphere as well as everything inside the sphere). The ball and the sphere share the same radius, diameter, and center.

Sphere (band)

Sphere is the name of the following musical groups:

Sphere (American band)

Sphere were an American jazz ensemble which began as a tribute to pianist/composer Thelonious Monk, whose middle name was "Sphere".

The band initially consisting of Monk's longtime tenor saxophonist Charlie Rouse, pianist Kenny Barron, bassist Buster Williams, and Monk's former drummer Ben Riley. Saxophonist Gary Bartz assumed Rouse's place after his death in 1988.
