Ejecta
Ejecta (from the Latin: "things thrown out", singular ejectum) are particles ejected from an area. In volcanology, in particular, the term refers to particles including pyroclastic materials (tephra) that came out of a volcanic explosion and magma eruption volcanic vent, or crater, has traveled through the air or under water, and fell back on the ground surface or on the ocean floor. Volcanology Typically in volcanology, ejecta is a result of explosive eruptions. In an explosive eruption, large amounts of gas are dissolved in extremely viscous lava; this lava froths to the surface until the material is expelled rapidly due to the trapped pressure. Sometimes in such an event a lava plug or volcanic neck forms from lava that solidifies inside a volcano's vent, causing heat and pressure to build up to an extreme with no way to escape. When the blockage breaks and cannot sustain itself any longer, a more violent eruption occurs, which allows materials to be ejected out of the volc ...

Ejecta (band)
Young Ejecta (formerly known as simply Ejecta) is an American synthpop duo, consisting of Neon Indian's Leanne Macomber and producer Joel Ford of Ford & Lopatin. The band name was changed to Young Ejecta in 2014 due to the group getting a copyright notice from the closely named DJ Ejeca. Macomber appears nude on all official album covers and promotional material, and in most of their music videos. In an interview with Brooklyn Based, she gives the background "''Creating Ejecta as a sort of blank slate, Macomber set out to subvert any neat categorization of the band’s music. “I really insisted like, she should be naked all the time so that no one can say, ‘Well, they’re punks, they dress like this.'”''" History In November 2013, Ejecta released their debut album, '' Dominae''. In 2015 issued their mini-album and second studio LP '' The Planet''. The album received an indifferent review from PopMatters and a fairly positive one from ''Paste'' magazine. Heather Phares of ...

Ejecta (film)
''Ejecta'' is a 2014 Canadian science fiction horror film directed by Chad Archibald and Matt Wiele. The film's script was written by Tony Burgess and stars Julian Richings as a man that has experienced an extraterrestrial encounter. ''Ejecta'' had its world premiere on August 3, 2014 at Fantasia Festival and Canadian film rights were purchased by Anchor Bay Canada. Synopsis Filmmaker Joe Sullivan becomes excited when he receives an email from famously reclusive alien abductee William Cassidy. Believing that Cassidy wishes to grant him an exclusive interview, Sullivan travels to the address given. Along the way, he sees military vehicles, including tanks. When Sullivan arrives, Cassidy is uncooperative. Cassidy claims to have never heard of Sullivan and to have never sent an email, though he eventually relents to an interview. After briefly attempting to describe the psychological torture he suffered from his abduction, Cassidy explains that an upcoming solar flare, and th ...

Excretion
Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life. For example, in mammals, urine is expelled through the urethra, which is part of the excretory system. In unicellular organisms, waste products are discharged directly through the surface of the cell. During life activities such as cellular respiration, several chemical reactions take place in the body. These are known as metabolism. These chemical reactions produce waste products such as carbon dioxide, water, salts, urea and uric acid. Accumulation of these wastes beyond a level inside the body is harmful to the body. The excretory organs remove these wastes. This process of removal of metabolic waste from the body is known as excretion. Green plants produce carbon d ...

Firearm
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ejecta Blanket
An ejecta blanket is a generally symmetrical apron of ejecta that surrounds an impact crater; it is layered thickly at the crater's rim and thin to discontinuous at the blanket's outer edge. The impact cratering is one of the basic surface formation mechanisms of the solar system bodies (including the Earth) and the formation and emplacement of ejecta blankets are the fundamental characteristics associated with impact cratering event. The ejecta materials are considered as the transported materials beyond the transient cavity formed during impact cratering regardless of the state of the target materials. Formation A blanket of ejecta is formed during the formation of meteor impact cratering and is composed usually of the materials of that are ejected from the cratering process. Ejecta materials are deposited on the preexisting layer of target materials and therefore it form an inverted stratigraphy than the underlying bedrock. In some cases, the excavated fragment of ejects ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
