Chemical element

A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, Z). There are 118 elements that have been identified, of which the first 94 occur naturally on Earth with the remaining 24 being synthetic elements. There are 80 elements that have at least one stable isotope and 38 that have exclusively radioactive isotopes, which decay over time into other elements. Iron is the most abundant element (by mass) making up the Earth, while oxygen is the most common element in the crust of the earth.

Chemical elements constitute all of the ordinary matter of the universe. However astronomical observations suggest that ordinary observable matter is only approximately 15% of the matter in the universe: the remainder is dark matter, the composition of which is unknown, but it is not composed of chemical elements. The two lightest elements, hydrogen and helium were mostly formed in the Big Bang and are the most common elements in the universe. The next three elements (lithium, beryllium and boron) were formed mostly by cosmic ray spallation, and are thus more rare than those that follow. Formation of elements with from six to twenty six protons occurred and continues to occur in main sequence stars via stellar nucleosynthesis. The high abundance of oxygen, silicon, and iron on Earth reflects their common production in such stars. Elements with greater than twenty-six protons are formed by supernova nucleosynthesis in supernovae, which, when they explode, blast these elements far into space as planetary nebulae, where they may become incorporated into planets when they are formed.

Element (criminal law)

Under United States law, an element of a crime (or element of an offense) is one of a set of facts that must all be proven to convict a defendant of a crime. Before a court finds a defendant guilty of a criminal offense, the prosecution must present evidence that, even when opposed by any evidence the defense may choose to present, is credible and sufficient to prove beyond a reasonable doubt that the defendant committed each element of the particular crime charged. The component parts that make up any particular crime vary depending on the crime.

The basic components of an offense are listed below; generally, each element of an offense falls into one or another of these categories. At common law, conduct could not be considered criminal unless a defendant possessed some level of intention — either purpose, knowledge, or recklessness — with regard to both the nature of his alleged conduct and the existence of the factual circumstances under which the law considered that conduct criminal. However, for some legislatively enacted crimes, the most notable example being statutory rape, a defendant need not have had any degree of belief or willful disregard as to the existence of certain factual circumstances (such as the age of the accuser) that rendered his conduct criminal; such crimes are known as strict liability offenses.

Element (UML)

In the Unified Modeling Language (UML), an Element is an abstract class with no superclass. It is used as the superclass or base class, as known by object oriented programmers, for all the metaclasses in the UML infrastructure library. All other elements in the UML inherit, directly or indirectly from Element. An Element has a derived composition association to itself to support the general capability for elements to own other elements. As such, it has no additional attributes as part of its specification.

Associations

An association describes a set of tuples of typed instances.

Burn (Deep Purple song)

"Burn" is a song by British rock band Deep Purple. It was released on the album of the same name in 1974, and was the first song by the Mark III lineup. The song remained the band's concert opener for the next two years, taking over from "Highway Star". It opened Deep Purple's set on the California Jam two months after its release, on 6 April 1974.

After the Deep Purple 1984 reunion, the song was no longer played, as Ian Gillan, whom David Coverdale had replaced, was vocalist once more, and would not sing songs from the Coverdale era. The band did perform "Burn" live in 1991, during the time in which Gillan was briefly replaced by Joe Lynn Turner. When Gillan once more returned to the band in 1992, he again refused to perform Coverdale-era songs.

After Deep Purple's 1976 split-up, Coverdale formed his own band, Whitesnake, which over the years has featured Deep Purple members such as Jon Lord, Ian Paice and Don Airey, and has performed Coverdale-era Deep Purple songs such as "Burn", "Lady Double Dealer", "Lady Luck", "Mistreated", "Might Just Take Your Life", "Soldier of Fortune" and "Stormbringer". Glenn Hughes also features the song regularly in his live solo performances, as well as with his project, the supergroup Black Country Communion.

Burn (Havok album)

Burn is the first full-length album recorded by the thrash metal band, Havok. It was released in 2009 on Candlelight Records.

Background

Drum, bass and guitar recording started in mid-2008 in the basement of singer/guitarist David Sanchez's mother's house, in Lakewood, CO. It took roughly 6 months. Vocals were recorded later at Motaland Studios in Denver with engineer Bart McCrorey, who also mixed the album. The band did not work with a producer due to a limited budget of roughly $2,500.

Halsey Swain provided the artwork after an earlier version of the same concept by another artist was rejected.

The album consists of 5 tracks that had been previously released on various EPs or demos and 7 tracks that were original to the album. Bassist Justin Cantrell contributed "Morbid Symmetry" to the songwriting process, but left the band before recording began. This track was designated the "single" for the album, though no actual single was ever released. Jessie De Los Santos replaced him. Drummer Ryan Bloom left the band shortly before the album's release date and was not permanently replaced until 2010. His credit on the album reads, "drum tracks by Ryan Bloom," and he was the lyricist for "Ivory Tower."

Burn (Mobb Deep song)

"Burn" is the first single from Mobb Deep's fifth album Infamy. The song features Big Noyd and Vita. On the album, the track is listed as "The Learning (Burn)".

Background

Prodigy's verse contains a subliminal diss towards Jay-Z, in response to the song Takeover.

Music Video

The music video was directed by Diane Martel & features a cameo by DJ Kay Slay. Although Vita is on the chorus of the song, she does not appear in the music video for the song due to Mobb Deep's Beef with Jay-Z (who had a strong relationship with her record label Murder Inc Records.
