Retarder (album)
''Retarder'' is The Unband's first major label release. In Brief "Every number is a testament to the might and stamina of the power chord." -''Las Vegas Weekly'' "They have the amusing habit -- check out "Ski Hat," "Dope (Part 2)," and especially "$#@?!!"—of riffing straight through what would usually be a song's first couple of verses, throwing in a few lines of debauched lyrics, then cutting the whole thing off around the two-minute mark. It's these controlled doses of alcoholic incoherency, along with more traditional barn burners like "Too Much Is Never Enough," that make Retarder a keeper." -''The Boston Phoenix'' Track listing # Geez Louise 3:24 # Too Much Is Never Enough 2:35 # Rock Hard 3:41 # Jilt 3:00 # Ski Hat 2:09 # $#@?!! 2:14 # Pink Slip 3:00 # Crack Soundtrack 3:44 # Everybody Wants You 4:09 # Get With You 2:54 # (Sure Do Feel Like A) Piece of Shit 3:06 # Dope, Pt. 2 2:42 # Cocaine Whore ...

Retarder (chemistry)
A retarder is a chemical agent that slows down a chemical reaction. For example, retarders are used to slow the chemical reaction hardening of plastic materials such as wallboard, concrete, and adhesives. Sugar water acts as a retarder for the curing of concrete. It can be used to retard the chemical hardening of the surface, so that the top layer can be washed off to expose the underlying aggregate Aggregate or aggregates may refer to: Computing and mathematics * collection of objects that are bound together by a root entity, otherwise known as an aggregate root. The aggregate root guarantees the consistency of changes being made within the ....

Retarder (mechanical Engineering)
A retarder is a device used to augment or replace some of the functions of primary friction-based braking systems, usually on heavy vehicles. Retarders serve to slow vehicles, or maintain a steady speed while traveling down a hill, and help prevent the vehicle from "running away" by accelerating down the hill. They are not usually capable of bringing vehicles to a standstill, as their effectiveness diminishes as vehicle speed lowers. They are usually used as an additional "assistance" to slow vehicles, with the final braking done by a conventional friction braking system. As the friction brake will be used less, particularly at higher speeds, their service life is increased, and since in those vehicles the brakes are air-actuated helps to conserve air pressure too. Friction-based braking systems are susceptible to "brake fade" when used extensively for continuous periods, which can be dangerous if braking performance drops below what is required to stop the vehicle – for ins ...

Retarder (railroad)
In rail transport, a retarder is a device installed in a classification yard used to reduce the speed of freight cars as they are sorted into trains. Construction Each retarder consists of a series of stationary brakes surrounding a short section of each on the track that grip and slow the cars' wheels through friction as they roll through them. Computer control Modern retarders are computer controlled to apply a precise amount of pressure on the wheels so that cars rolling down a yard's hump are slowed to a safe speed for coupling with cars already standing on the yard's tracks. Inert retarder An inert retarder holds a cut of classified railcars to keep them from rolling out of a yard.U.S. Federal Railroad Administration, Washington, D.C.

Acrylic Retarder
In painting, a retarder is a substance, usually a glycol and usually added to water, that is used to slow the drying time of acrylic paints, giving more time for blending or layering highlights. Use in fine art Retarders are used to counter the fast drying properties of acrylic paints, making possible the usage of wet-on-wet or other techniques which would otherwise require oil paints. When used correctly, they can keep the paint wet from half an hour extra to a full day's working time. Applying too much retardant, however, can prevent a layer from drying correctly for as long as the retardant is present, causing future damage to the painting unless the affected layer of paint is removed or re-mixed. Content They generally contain glycol (such as propylene glycol) or glycerin-based additives. Home-Made For home-made acrylic retarder, water glycerol Glycerol (), also called glycerine in British English and glycerin in American English, is a simple triol compound. It is a ...

Proofing (baking Technique)
In cooking, proofing (also called proving) is a step in the preparation of yeast bread and other baked goods in which the dough is allowed to rest and rise a final time before baking. During this rest period, yeast ferments the dough and produces gases, thereby leavening the dough. In contrast, proofing or blooming ''yeast'' (as opposed to proofing the dough) may refer to the process of first suspending yeast in warm water, a necessary hydration step when baking with active dry yeast.Instant dry yeast may be placed directly into flour without hydrating first. Proofing can also refer to the process of testing the viability of dry yeast by suspending it in warm water with carbohydrates (sugars). If the yeast is still alive, it will feed on the sugar and produce a visible layer of foam on the surface of the water mixture. Fermentation rest periods are not always explicitly named, and can appear in recipes as "Allow dough to rise." When they are named, terms include "bulk fermentat ...

Retardation Plate
A waveplate or retarder is an optical device that alters the polarization state of a light wave travelling through it. Two common types of waveplates are the ''half-wave plate'', which shifts the polarization direction of linearly polarized light, and the ''quarter-wave plate'', which converts linearly polarized light into circularly polarized light and vice versa. A quarter-wave plate can be used to produce elliptical polarization as well. Waveplates are constructed out of a birefringent material (such as quartz or mica, or even plastic), for which the index of refraction is different for light linearly polarized along one or the other of two certain perpendicular crystal axes. The behavior of a waveplate (that is, whether it is a half-wave plate, a quarter-wave plate, etc.) depends on the thickness of the crystal, the wavelength of light, and the variation of the index of refraction. By appropriate choice of the relationship between these parameters, it is possible to introduce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weapon
A weapon, arm or armament is any implement or device that can be used to deter, threaten, inflict physical damage, harm, or kill. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime, law enforcement, self-defense, warfare, or suicide. In broader context, weapons may be construed to include anything used to gain a tactical, strategic, material or mental advantage over an adversary or enemy target. While ordinary objects – sticks, rocks, bottles, chairs, vehicles – can be used as weapons, many objects are expressly designed for the purpose; these range from simple implements such as clubs, axes and swords, to complicated modern firearms, tanks, intercontinental ballistic missiles, biological weapons, and cyberweapons. Something that has been re-purposed, converted, or enhanced to become a weapon of war is termed weaponized, such as a weaponized virus or weaponized laser. History The use of weapons is a major driver of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rate Of Fire
Rate of fire is the frequency at which a specific weapon can fire or launch its projectiles. This can be influenced by several factors, including operator training level, mechanical limitations, ammunition availability, and weapon condition. In modern weaponry, it is usually measured in rounds per minute (RPM or round/min) or rounds per second (RPS or round/s). There are three different measurements for the rate of fire: cyclic, sustained, and rapid. Cyclic is the maximum rate of fire given only mechanical function, not taking into account degradation of function due to heat, wear, or ammunition constraints. Sustained is the maximum efficient rate of fire given the time taken to load the weapon and keep it cool enough to operate. Finally, rapid is the maximum reasonable rate of fire in an emergency when the rate of fire need not be upheld for long periods. Overview For manually operated weapons such as bolt-action rifles or artillery pieces, the rate of fire is governed primarily ...
