Expansion Joint
An expansion joint, or movement joint, is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials, and vibration, or to allow movement due to ground settlement or seismic activity. They are commonly found between sections of buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures. Building faces, concrete slabs, and pipelines expand and contract due to warming and cooling from seasonal variation, or due to other heat sources. Before expansion joint gaps were built into these structures, they would crack under the stress induced. Bridge expansion joints Bridge expansion joints are designed to allow for continuous traffic between structures while accommodating movement, shrinkage, and temperature variations on reinforced and prestressed concrete, composite, and steel structures. They stop the bridge from bending out of place in extreme conditions, and also allow eno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expansionism
Expansionism refers to states obtaining greater territory through military empire-building or colonialism. In the classical age of conquest moral justification for territorial expansion at the direct expense of another established polity (who often faced displacement, subjugation, slavery, rape and execution) was often as unapologetic as "because we can" treading on the philosophical grounds of might makes right. As political conceptions of the nation state evolved, especially in reference to the inherent rights of the governed, more complex justifications arose. State-collapse anarchy, reunification or pan-nationalism are sometimes used to justify and legitimize expansionism when the explicit goal is to reconquer territories that have been lost or to take over ancestral lands. Lacking a viable historical claim of this nature, would-be expansionists may instead promote ideologies of promised lands (such as manifest destiny or a religious destiny in the form of a Promised Land ...

Expansion Team
An expansion team is a new team in a sports league, usually from a city that has not hosted a team in that league before, formed with the intention of satisfying the demand for a local team from a population in a new area. Sporting leagues also hope that the expansion of their competition will grow the popularity of the sport generally. The term is most commonly used in reference to the North American major professional sports leagues but is applied to sports leagues in other countries with a closed franchise system of league membership. The term refers to the expansion of the sport into new areas. The addition of an expansion team sometimes results in the payment of an expansion fee to the league by the new team and an expansion draft to populate the new roster. Reasons for expansion In North America, expansion often takes place in response to population growth and geographic shifts of population. Such demographic change results in financial opportunities to engage with the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expansion (economics)
An economic expansion is an increase in the level of economic activity, and of the goods and services available. It is a period of economic growth as measured by a rise in real GDP. The explanation of fluctuations in aggregate economic activity between economic expansions and contractions is one of the primary concerns of macroeconomics. Typically an economic expansion is marked by an upturn in production and utilization of resources. Economic recovery and prosperity are two successive phases of expansion, where as a recession is defined as two declining periods of GDP. Expansion may be caused by factors external to the economy, such as weather conditions or technical change, or by factors internal to the economy, such as fiscal policies, monetary policies, the availability of credit, interest rates, regulatory policies or other impacts on producer incentives. Global conditions may influence the levels of economic activity in various countries. Economic contraction and expa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expansion Of The Universe
The expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observable universe with time. It is an intrinsic expansion whereby the scale of space itself changes. The universe does not expand "into" anything and does not require space to exist "outside" it. This expansion involves neither space nor objects in space "moving" in a traditional sense, but rather it is the metric (which governs the size and geometry of spacetime itself) that changes in scale. As the spatial part of the universe's spacetime metric increases in scale, objects become more distant from one another at ever-increasing speeds. To any observer in the universe, it appears that all of space is expanding, and that all but the nearest galaxies (which are bound by gravity) recede at speeds that are proportional to their distance from the observer. While objects within space cannot travel faster than light, this limitation does not apply to the effects of ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Expansion
Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, molecules begin to vibrate and move more, usually creating more distance between themselves. Substances which contract with increasing temperature are unusual, and only occur within limited temperature ranges (see examples below). The relative expansion (also called strain) divided by the change in temperature is called the material's coefficient of linear thermal expansion and generally varies with temperature. As energy in particles increases, they start moving faster and faster weakening the intermolecular forces between them, therefore expanding the substance. Overview Predicting expansion If an equation of state is available, it can be used to predict the values of the thermal expan ...

Joule–Thomson Effect
In thermodynamics, the Joule–Thomson effect (also known as the Joule–Kelvin effect or Kelvin–Joule effect) describes the temperature change of a ''real'' gas or liquid (as differentiated from an ideal gas) when it is forced through a valve or porous plug while keeping it insulated so that no heat is exchanged with the environment. This procedure is called a ''throttling process'' or ''Joule–Thomson process''. At room temperature, all gases except hydrogen, helium, and neon cool upon expansion by the Joule–Thomson process when being throttled through an orifice; these three gases experience the same effect but only at lower temperatures. Most liquids such as hydraulic oils will be warmed by the Joule–Thomson throttling process. The gas-cooling throttling process is commonly exploited in refrigeration processes such as liquefiers in air separation industrial process. In hydraulics, the warming effect from Joule–Thomson throttling can be used to find internal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expansion Chamber
On a two-stroke engine, an expansion chamber or tuned pipe is a tuned exhaust system used to enhance its power output by improving its volumetric efficiency. History Expansion chambers were invented and successfully manufactured by Limbach, a German engineer, in 1938, to economize fuel in two stroke engines. Germany was running short of petrol, which was at that stage produced using coal and sewage transformation. An unexpected bonus was that the two stroke engines using tuned exhausts produced far more power than if running with a normal silencer. After the end of the second world war, some time passed before the concept was re-developed by East German Walter Kaaden during the Cold War. They first appeared in the west on Japanese motorcycles after East German motorcycle racer Ernst Degner defected to the west while racing for MZ in the 1961 Swedish Grand Prix. He later passed his knowledge to Japan's Suzuki. How it works The high pressure gas exiting the cylinder initiall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expansion (album)
''Expansion'' is a live album released by jazz pianist Dave Burrell. It was recorded during a number of concerts in December 2003 and was released on June 8, 2004 by High Two. The group that Burrell toured with was referred to as the Full-Blown Trio and included Burrell, Andrew Cyrille (drums) and William Parker ( bass). Reception AllMusic calls the album "a lovely record ... by a trio versed in understatement and nuance." Reviewer Thom Jurek in particular comments on Burrell's playing by saying that his "fills between the lyric lines are humorous, warm, and dazzling." ''The Penguin Guide to Jazz'' also mention that the three men "gel perfectly" and they provide him with the most flattering context for years."''The Penguin Guide to Jazz'' by Richard Cook, Brian Morton, et al. pg 190.
