An album cover is the front of the packaging of a commercially released audio recording product, or album.
 The term can refer to either the printed cardboard covers typically used to package sets of 10 in and 12 in 78-rpm records, single and sets of 12 in LPs, sets of 45 rpm records (either in several connected sleeves or a box), or the front-facing panel of a CD package, and, increasingly, the primary image accompanying a digital download of the album, or of its individual tracks.
Graham Gold (born 5 July 1954) is a British DJ.
 Gold is primarily known as a DJ whose sets were broadcast live Friday nights on Kiss (UK radio station) and distributed on the Universal Music TV label.
 These weekly live broadcasts were considered revolutionary in the industry.
 Gold's popular weekly show played a major role in Kiss FM growing into a radio powerhouse.
 Gold was ranked #83 by Dash Berlin in Dash's "Most Popular DJs in the World of All Time."
In algebraic geometry, a group-stack is an algebraic stack whose categories of points have group structures or even groupoid structures in a compatible way.
 It generalizes a group scheme, which is a scheme whose sets of points have group structures in a compatible way.
In matroid theory, a binary matroid is a matroid that can be represented over the finite field GF(2).
 That is, up to isomorphism, they are the matroids whose elements are the columns of a (0,1)-matrix and whose sets of elements are independent if and only if the corresponding columns are linearly independent in GF(2).
Nickelodeon Launch Box is an educational television series that was produced jointly by Nickelodeon and NASA.
 It was meant to teach kids about space travel technology.
 As part of the Cable in the Classroom service, the show was intended to be taped by teachers and shown in the classroom.
 Each episode also included a teachers portion before and after where ideas for lessons and other aides were discussed.
 The show was taped before a live studio audience at Nickelodeon Studios and made use of many sets for Nickelodeon shows such as "What Would You Do?
" and "Double Dare".
What Would You Do?
 is a 30-minute television show hosted by Marc Summers shown on Nickelodeon from 1991 to 1993.
 Robin Marrella acted as the on-camera stagehand for the show's first season.
 Both Summers and Marrella performed their respective duties on "Double Dare", also on Nickelodeon.
 The show was produced in Nickelodeon Studios at Universal Studios in Florida; some early segments were produced at Universal Studios in Hollywood.
The Survivors were a Brisbane punk rock band that originally formed in 1976 as Rat Salad, a party band, The Survivors attained cult status in Australia by their acknowledged popular live performances and contribution to the "Lethal Weapons" punk compilation album.
 Original band members were Greg Williamson on guitar and vocals, Jim Dickson on bass guitar and vocals, Bruce Anthon on drums and vocals.
 David Nichols, from the "Mess And Noise" website, commented that, "The Survivors were legends in their home town of Brisbane, a highly popular and adept band whose sets were mainly cool ’60s covers."
In mathematics, a Baire measure is a measure on the σ-algebra of Baire sets of a topological space whose value on every compact Baire set is finite.
 In compact metric spaces the Borel sets and the Baire sets are the same, so Baire measures are the same as Borel measures that are finite on compact sets.
 In general Baire sets and Borel sets need not be the same.
 In this context, Baire measures are used because they connect to the properties of continuous functions more directly.
Nickelodeon's 23rd Annual Kids' Choice Awards (Nickelodeon Kids' Choice Awards 2010) were held on March 27, 2010 (aired live from 8-9:30 p.m. ET) on the Nell and John Wooden Court of Pauley Pavilion, on the campus of UCLA in Los Angeles, California.
 With the launch of Nickelodeon Canada in late 2009, Canada broadcast the awards live as it aired in the Eastern, Central, and Mountain time zones of the United States (it was tape-delayed for the Pacific Time Zone) and the awards will be rebroadcast on YTV on April 2, 2010 at 7 p.m. ET.
 As a result, Canadian kids were able to vote on candidates for the first time.
 Nickelodeon's sister channels TeenNick and Nicktoons suspended regular programming during the 90-minute duration of the award show to allow viewers to see the awards.
 The 2010 awards were hosted by Kevin James, who is a first-time "Kids' Choice" host.
In mathematics, an equidistant set (also called a midset, or a bisector) is a set each of whose elements has the same distance (measured using some appropriate distance function) from two or more sets.
 The equidistant set of two singleton sets in the Euclidean plane is the perpendicular bisector of the segment joining the two sets.
 The conic sections can also be realized as equidistant sets.
 This property of conics has been used to generalize the notion of conic sections.
 The concept of equidistant set is used to define frontiers in territorial domain controversies.
 For instance, the United Nations Convention on the Law of the Sea (Article 15) establishes that, in absence of any previous agreement, the delimitation of the territorial sea between countries occurs exactly on the median line every point of which is equidistant of the nearest points to each country.
 Though the usage of the terminology is quite old, the study of the properties of equidistant sets as mathematical objects was initiated only in 1970's.
