Solidification
Freezing is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point. In accordance with the internationally established definition, freezing means the solidification phase change of a liquid or the liquid content of a substance, usually due to cooling. For most substances, the melting and freezing points are the same temperature; however, certain substances possess differing solid-liquid transition temperatures. For example, agar displays a hysteresis in its melting point and freezing point. It melts at 85 °C (185 °F) and solidifies from 32 °C to 40 °C (89.6 °F to 104 °F). Crystallization Most liquids freeze by crystallization, formation of crystalline solid from the uniform liquid. This is a first-order thermodynamic phase transition, which means that as long as solid and liquid coexist, the temperature of the whole system remains very nearly equal to the melting point due to the slow re ...

Scottish Country Dance
Scottish country dance (SCD) is the distinctively Scottish form of country dance, itself a form of social dance involving groups of couples of dancers tracing progressive patterns. A dance consists of a sequence of figures. These dances are set to musical forms (Jigs, Reels and Strathspey Reels) which come from the Gaelic tradition of Highland Scotland, as do the steps used in performing the dances. Traditionally a figure corresponds to an eight-bar phrase of music. Country dancing, which is arguably a type of folk dancing, first appears in the historical record in 17th-century England. Scottish country dancing as we know it today has its roots in an 18th-century fusion of (English) country dance formations with Highland music and footwork. It has become the national ballroom dance form of Scotland, partly because "Caledonian Country Dances" became popular in upper-class London society in the decades after the Jacobite rising of 1745. As early as 1724 there was a published ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Square Dance
A square dance is a dance for four couples, or eight dancers in total, arranged in a square, with one couple on each side, facing the middle of the square. Square dances contain elements from numerous traditional dances and were first documented in 16th-century England, but they were also quite common in France and throughout Europe. Early square dances, particularly English country dances and French quadrilles, traveled to North America with the European settlers and developed significantly there. In some countries and regions, through preservation and repetition, square dances have attained the status of a folk dance. Square dancing is strongly associated with the United States, in part due to its association with the romanticized image of the American cowboy in the 20th century, and 31 states have designated it as their official state dance. The main North American types of square dances include traditional square dance and modern western square dance, which is widely k ...

Suzuki SET
A four-stroke power valve is a device fitted to four-stroke engines that constantly adjusts the internal diameter of the exhaust system to better suit the speed of the engine. Yamaha was the first to develop such a system, called the Exhaust Ultimate Power Valve (EXUP). It first appeared on the Yamaha FZR EXUP and was later used on many other Yamahas. Later versions from Honda went by the names Honda Titanium Exhaust Valve (HTEV) and Honda Variable Intake/Exhaust (H-VIX), appearing on the CBR600RR and Honda CBR929RR. Suzuki's version is called Suzuki Exhaust Tuning (SET). The system is also used on the Triumph Daytona 675 triple. Operation At low engine speeds, the wave pressure within the pipe network is low. A full oscillation of the Helmholtz resonance occurs before the exhaust valve is closed, and to increase low-speed torque, large-amplitude exhaust pressure waves are artificially induced. This is done by partial closing of an internal butterfly valve within the exhaust w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quality Assurance
Quality assurance (QA) is the term used in both manufacturing and service industries to describe the systematic efforts taken to ensure that the product(s) delivered to customer(s) meet with the contractual and other agreed upon performance, design, reliability, and maintainability expectations of that customer. The core purpose of Quality Assurance is to prevent mistakes and defects in the development and production of both manufactured products, such as automobiles and shoes, and delivered services, such as automotive repair and athletic shoe design. Assuring quality and therefore avoiding problems and delays when delivering products or services to customers is what ISO 9000 defines as that "part of quality management focused on providing confidence that quality requirements will be fulfilled". This defect prevention aspect of quality assurance differs from the defect detection aspect of quality control and has been referred to as a ''shift left'' since it focuses on quality eff ...

Simulated Emergency Test
The annual Simulated Emergency Test (SET) is a training exercise involving the Amateur Radio Emergency Service (ARES) and the National Traffic System (NTS), a message-handling service of amateur radio. The American Radio Relay League is a prime mover in this event, which is organized somewhat like a contest. Its primary purposes are to evaluate strengths and weaknesses in emergency preparedness and communications, and to demonstrate amateur radio to the public. During the first full weekend of October of every year in the United States, a nationwide radio communications network is set up that links every major city and most of the geography of the country. This technological infrastructure is set up from scratch within a few hours at locations that vary from state and local government Emergency Operations Centers to isolated areas without utilities of any kind. Every mode of radio communications is utilized including analog, digital, voice, data, simplex, duplex, satellites a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Setting (typesetting)
Typesetting is the composition of text by means of arranging physical ''type'' (or ''sort'') in mechanical systems or ''glyphs'' in digital systems representing '' characters'' (letters and other symbols).Dictionary.com Unabridged. Random House, Inc. 23 December 2009Dictionary.reference.com/ref> Stored types are retrieved and ordered according to a language's orthography for visual display. Typesetting requires one or more fonts (which are widely but erroneously confused with and substituted for typefaces). One significant effect of typesetting was that authorship of works could be spotted more easily, making it difficult for copiers who have not gained permission. Pre-digital era Manual typesetting During much of the letterpress era, movable type was composed by hand for each page by workers called compositors. A tray with many dividers, called a case, contained cast metal '' sorts'', each with a single letter or symbol, but backwards (so they would print correctly). T ...

Scalar Expectancy
The scalar timing or scalar expectancy theory (SET) is a model of the processes that govern behavior controlled by time. The model posits an internal clock, and particular memory and decision processes. SET is one of the most important models of animal timing behavior. History John Gibbon John Gibbon (April 20, 1827 – February 6, 1896) was a career United States Army officer who fought in the American Civil War and the Indian Wars. Early life Gibbon was born in the Holmesburg section of Philadelphia, Pennsylvania, the fou ... originally proposed SET to explain the temporally controlled behavior of non-human subjects. He initially used the model to account for a pattern of behavior seen in animals that are being reinforced at fixed-intervals, for example every 2 minutes. An animal that is well trained on such a fixed-interval schedule pauses after each reinforcement and then suddenly starts responding about two-thirds of the way through the new interval.
