Explosion
An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be generated by a slower expansion that would normally not be forceful, but is not allowed to expand, so that when whatever is containing the expansion is broken by the pressure that builds as the matter inside tries to expand, the matter expands forcefully. An example of this is a Volcano, volcanic eruption created by the expansion of magma in a magma chamber as it rises to the surface. Supersonic explosions created by high explosives are known as detonations and travel through shock waves. wikt:subsonic, Subsonic explosions are created by low explosives through a slower combustion process known as deflagration. Causes For an explosion to occur, there must be a rapid, forceful expansion of matter. There are numerous ways this can happen, both natura ...

Blast (album)
''Blast'' is the debut solo album by the English singer and musician Holly Johnson. It was released in 1989 and reached No. 1 in the UK Albums Chart and sold over 300,000 copies making it platinum. The album stayed on the charts for 17 weeks. The album features the hits "Love Train", "Americanos", "Atomic City" and "Heaven's Here". The album was re-released in November 2009 and again in November 2010. In 2010, Johnson marked "Love Will Come" and "Heaven's Here" as his favourite tracks from the album. The album's title ''Blast'' came from the short-lived magazine of the early-20th century British Vorticist art movement.

Bell Laboratories Layered Space-Time
Bell Laboratories Layer Space-Time (BLAST) is a transceiver architecture for offering spatial multiplexing over multiple-antenna wireless communication systems. Such systems have multiple antennas at both the transmitter and the receiver in an effort to exploit the many different paths between the two in a highly-scattering wireless environment. BLAST was developed by Gerard Foschini at Lucent Technologies' Bell Laboratories (now Nokia Bell Labs). By careful allocation of the data to be transmitted to the transmitting antennas, multiple data streams can be transmitted simultaneously within a single frequency band — the data capacity of the system then grows directly in line with the number of antennas (subject to certain assumptions). This represents a significant advance on current, single-antenna systems. V-BLAST V-BLAST (Vertical-Bell Laboratories Layered Space-Time) is a detection algorithm to the receipt of multi-antenna MIMO systems. Available for the first time in 1996 ...

BLAST Network
The BLAST network is a previous iteration of a plan for a frequent rapid transit system in the city of Hamilton, Ontario, Canada. The system is planned to include five routes, with one light rail transit (LRT) line, and four bus rapid transit (BRT) lines. In 2019, the City of Hamilton launched a project entitled ''(Re)envision the HSR'', which was an evolution on the BLAST network. The new plan includes an additional E-Line. As a result, the BLAST network branding is no longer used. Background In 1981, during Bill Davis's Progressive Conservative administration, the Province of Ontario offered to finance the construction of a light metro in Hamilton from Lloyd D. Jackson Square to the Lime Ridge Mall. The line would have employed the ICTS platform used in the Scarborough RT in Toronto and the Expo Line in Vancouver. The plan, however, faced significant local opposition, and Hamilton-Wentworth Council rejected the proposal. The plan called for an elevated trackone of the el ...

Blast Injury
A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space. Classification Blast injuries are divided into four classes: primary, secondary, tertiary, and quaternary. Primary injuries Primary injuries are caused by blast overpressure waves, or shock waves. Total body disruption is the most severe and invariably fatal primary injury. Primary injuries are especially likely when a person is close to an exploding munition, such as a land mine. The ears are most often affected by the overpressure, followed by the lungs and the hollow organs of the gastrointestinal tract. Gastrointestinal injuries may present after a delay of hours or even days. Injury from blast overpressure is a pressure and time dependent function. By increasing the p ...

Blast Disease
''Magnaporthe grisea'', also known as rice blast fungus, rice rotten neck, rice seedling blight, blast of rice, oval leaf spot of graminea, pitting disease, ryegrass blast, Johnson spot, neck blast, wheat blast and , is a plant-pathogenic fungus and model organism that causes a serious disease affecting rice. It is now known that ''M. grisea'' consists of a cryptic species complex containing at least two biological species that have clear genetic differences and do not interbreed. Complex members isolated from ''Digitaria'' have been more narrowly defined as ''M. grisea''. The remaining members of the complex isolated from rice and a variety of other hosts have been renamed ''Magnaporthe oryzae'', within the same ''M. grisea'' complex. Confusion on which of these two names to use for the rice blast pathogen remains, as both are now used by different authors. Members of the ''M. grisea'' complex can also infect other agriculturally important cereals including wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blast Cell
In cell biology, precursor cells—also called blast cells—are partially differentiated, or intermediate, and are sometimes referred to as progenitor cells. A precursor cell is a stem cell with the capacity to differentiate into only one cell type, meaning they are unipotent stem cells. In embryology, precursor cells are a group of cells that later differentiate into one organ. However, progenitor cells are considered multipotent. Due to their contribution to the development of various organs and cancers, precursor and progenitor cells have many potential uses in medicine. There is ongoing research on using these cells to build heart valves, blood vessels, and other tissues by using blood and muscle precursor cells.

BLAST (biotechnology)
In bioinformatics, BLAST (basic local alignment search tool) is an algorithm and program for comparing Primary structure, primary biological sequence information, such as the amino acid, amino-acid sequences of proteins or the nucleotides of DNA sequence, DNA and/or RNA sequences. A BLAST search enables a researcher to compare a subject protein or nucleotide sequence (called a query) with a library or database of sequences, and identify database sequences that resemble the query sequence above a certain threshold. For example, following the discovery of a previously unknown gene in the Mus musculus, mouse, a scientist will typically perform a BLAST search of the human genome to see if humans carry a similar gene; BLAST will identify sequences in the human genome that resemble the mouse gene based on similarity of sequence. Background BLAST is one of the most widely used bioinformatics programs for sequence searching. It addresses a fundamental problem in bioinformatics research ...

BLAST (telescope)
The Balloon-borne Large Aperture Submillimeter Telescope (BLAST) is a submillimeter telescope that hangs from a high-altitude balloon. It has a 2-meter primary mirror that directs light into bolometer arrays operating at 250, 350, and 500 μm. These arrays were developed for the SPIRE instrument on the Herschel Space Observatory. The project is carried out by a multi-university consortium headed by the University of Pennsylvania and which also includes University of Toronto, Brown University, the University of Miami, the University of British Columbia, JPL, INAOE, and Cardiff University. The third flight of BLAST in Antarctica was a scientific success, but much of telescope was destroyed after landing. It has been rebuilt for a flight from Antarctica in the 2010-11 austral summer. This most recent flight of BLAST (aka BLAST-Pol) has a polarimeter to observe the polarized light from star forming cores. The light is polarized due to magnetic fields. It is thought that the ...

BLAST (protocol)
BLAST (Blocked Asynchronous Transmission), like XMODEM and Kermit, is a communications protocol designed for file transfer over asynchronous communication ports and dial-up modems that achieved a significant degree of popularity during the 1980s. Reflecting its status as a ''de facto'' standard for such transfers, BLAST, along with XMODEM, was briefly under official consideration by ANSI in the mid-80s as part of that organization's ultimately futile attempt to establish a single ''de jure'' standard. Overview BLAST grew out of the mission-critical experience of providing air pollution telemetry within the dial-up communications environment of the petroleum belt of southern Louisiana and Texas, with not only noisy telephone lines but also unexpected satellite hops to remote locations.Smith, G.

Blast Beat
A blast beat is a type of drum beat that originated in hardcore punk and grindcore, and is often associated with certain styles of extreme metal, namely black metal, death metal and their respective subgenres,Adam MacGregor, '' PCP Torpedo'' by Agoraphobic Nosebleed review, ''Dusted'', 11 June 2006 Access date: 2 October 2008. "There is one uniformly present attribute in all examples of 'grindcore', that being the so-called 'blast-beat.'" and occasionally in metalcore. In Adam MacGregor's definition, "the blast-beat generally comprises a repeated, sixteenth-note figure played at a very fast tempo, and divided uniformly among the bass drum, snare, and ride, crash, or hi-hat cymbal." Blast beats have been described by ''PopMatters'' contributor Whitney Strub as, "maniacal percussive explosions, less about rhythm per se than sheer sonic violence". According to Brad Schlueter of '' Drum!'', Napalm Death is said to have coined the term, though this style of drumming had previo ...
