Pipe bomb - Wikipedia, the free encyclopedia A pipe bomb is a simple type of improvised explosive device favored by criminals, a piece of pipe filled with an explosive material. There are at least two types of pipe bombs, those reaction between chemicals/gases, such as chlorate with sugar. Often times the use of a pipe bomb as a weapon is viewed as terrorism. en.wikipedia.org /wiki/Pipe_bomb   (470 words)

147. St. Helier - Volcanic Pipe The pipe is an important and rare exposure of igneous material of this nature.

Fish Containment Barriers The barrier design that best fulfills the requirements is a steel frame supporting a single row of vertical bars of some material such as stainless steel conduit or PVC pipe. As the width of the barrier increases, the horizontal channel and other material used to support the vertical bars should be of a heavier gauge to withstand pressures exerted from a head of water, should debris block the barrier. Steel rods may be inserted into the PVC pipe to add rigidity and strength to the design. edis.ifas.ufl.edu /BODY_AG009   (1498 words)

Volcanoes These diatremes, or volcanic pipes, can be exposed as tall structures on the surface after the surrounding softer material has been eroded away. A volcano is a hill or mountain that forms from the accumulation of material that erupts at the surface. Volcanic eruptions are often devastating and have destroyed many lives and property throughout recorded history. www.uh.edu /~geos6g/1330/volcanoes.html   (840 words)

Summary: Necks/Diatremes Acidic flows (silica rich) are lighter in tone, more viscous, contain more gas, and can solidify quickly enough to clog a vent--which causes periodic eruptions as volcanic forces clear the passage, widen fractures, and cause explosive implant of material to produce a pipe. These intrusive features are types of volcanic plugs, i.e., the fill within a volcanic pipe or vent. Pyroclastic material is rock that has been fragmented by explosive volcanic activity into particles that range in size from silt (ash), through gravel, to blocks several meters across. www.tec.army.mil /research/products/desert_guide/lsmsheet/lsnecks.htm   (541 words)

CVO Menu - America's Volcanic Past - Arkansas Tuff is a pyroclastic rock composed mostly of angular fragments of volcanic material deposited from the air. Epiclastic rock, which is a rock formed by the mechanical mixing of tuffaceous volcanic material and local Cretaceous sediments, was recently recognized by geologists. One of the few places in North America where diamonds are present in their host rock and the only place tourists may hunt for diamonds is the Prairie Creek pipe in Arkansas. vulcan.wr.usgs.gov /LivingWith/VolcanicPast/Places/volcanic_past_arkansas.html   (2952 words)

Volcanic pipe - Wikipedia, the free encyclopedia Lamproite pipes operate similarly to kimberlite pipes, except that the boiling water and volatile compounds contained in the magma act corrosioncorrosively on the overlying rock, resulting in a broader cone of eviscerated rock (the ejection of this rock also forms a tuff ring, like kimberlite eruptions). Volcanic pipes form as the result of violent eruptions of deep-origin volcanoes. The result is a martini-glass shaped deposit of volcanic material (both solidified magma, and ejecta) which appears mostly flat from the surface. en.wikipedia.org /wiki/Volcanic_pipe   (423 words)

Peace pipe - Wikipedia, the free encyclopedia A common material for calumet pipe bowls is red pipe stone or catlinite, a fine-grained easily-worked stone of a rich red color of the Coteau des Prairies, west of the Big Stone Lake in South Dakota. Pipes were shaped and roughed with hard sandstones and bow stone saws, and polished with water, then sanded with progressively finer and finer abrasive grit and animal hide, and the stone was finally rubbed with fat or facial oils to complete polishing. A peace pipe, also called a calumet or medicine pipe, is a ceremonial smoking pipe used by many Native American tribes. en.wikipedia.org /wiki/Peace_pipe   (811 words)

Volcanoes - everything you need to know Volcanism, processes by which molten rock material, or magma, rises from the interior of the Earth on to or towards its surface, and by which associated gases are released into the atmosphere. Surface, or continental, volcanism is much less important than sub-oceanic volcanism in terms of the volume of magma ejected, but much more is known about it because it is visible and directly affects human beings. Volcanic earthquakes and changes in the shape of volcanoes are two signals of impending eruptions. www.hecl.net /indonesia-adventure/volcanoesencarta.htm   (5171 words)

Inverted Siphon. Depressed Sewer. Design Calculations Unlike the main sewer pipe, the siphon pipes flow under pressure and must have flow velocities greater than 3 ft/s (0.9 m/s) to keep material suspended; therefore, several siphons having smaller diameters than the main sewer may be required. The piping going under the obstruction is traditionally called an "inverted siphon", but since the pipe is not actually acting as a siphon, a better term is "depressed sewer" (Metcalf and Eddy, 1981). Compute the siphon invert elevations in the inlet chamber. www.lmnoeng.com /Channels/InvertedSiphon.htm   (1338 words)

Barrier pipe - Wikipedia, the free encyclopedia The pipe is manufactured with a barrier that prevents oxygen from penetrating the material and entering the water system, reducing the risk of corrosion.

Performance Toyota: Exhaust Theory Overlarge piping will also allow our exhaust pulses to achieve a higher level of entropy, which will take all of our header tuning and throw it out the window, as pulses will not have the same tendency to line up as they would in a smaller pipe. Coating the entire exhaust system with an insulative material, such as header wrap or a ceramic thermal barrier coating reduces this effect somewhat, but unless you have lots of cash burning a hole in your pocket, is probably not worth the expense on a street driven car. From the catalytic converter, the exhaust gasses go through a bit more pipe and then into a muffler, or system consisting of several mufflers and/or resonators. www.geocities.com /MotorCity/7177/exhausttheory.html   (2753 words)

Diamond Encyclopedia Article, Description, History and Biography @ VariedTastes.com Below these typically small surface volcanic craters are formations known as volcanic pipes, which contain material that was pushed toward the surface of the earth by volcanic action, but did not erupt before the volcanic activity ceased. Diamond-bearing volcanic pipes are most commonly found in the oldest regions of continental crust, which relates to the fact that these areas are the coolest portions of the earth's crust, and therefore diamonds can form at the shallowest depths. The magma in such volcanic pipes is usually one of two characteristic types, which cool into igneous rock known as either kimberlite or lamproite. www.variedtastes.com /encyclopedia/Diamond   (8595 words)

8th INTERNATIONAL KIMBERLITE CONFERENCE (8IKC) The pipe is filled predominantly with a complex mixture of extrusive volcaniclastic kimberlite displaying varying degrees of reworking and incorporation of surficial mudstone, as both lithified clasts and as dark unconsolidated fine-grained matrix material. The morphology and internal geology of the pipes indicate dynamic and complex eruption histories, with the interplay between the various volcanic processes probably influenced by a combination of the near-surface country rock geology and hydrogeological conditions, as well as the ascending magma. All higher structural levels of pipes (which are usually volumetrically more important regarding their ore reserves) within those fields are eroded, which thus also includes smaller pipes, shallow root zones and all forms of volcanic surface expressions of the kimberlites as e.g. www.venuewest.com /8IKC/s1post.htm   (13979 words)
