Shrinkage (casting)
In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a sprue. The metal and mold are then cooled, and the metal part (the ''casting'') is extracted. Casting is most often used for making complex shapes that would be difficult or uneconomical to make by other methods. Casting processes have been known for thousands of years, and have been widely used for sculpture (especially in bronze), jewelry in precious metals, and weapons and tools. Highly engineered castings are found in 90 percent of durable goods, including cars, trucks, aerospace, trains, mining and construction equipment, oil wells, appliances, pipes, hydrants, wind turbines, nuclear plants, medical devices, defense products, toys, and more. Traditional techniques include los ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Creep And Shrinkage Of Concrete
Creep and shrinkage of concrete are two physical properties of concrete. The Creep (deformation), creep of concrete, which originates from the calcium silicate hydrates (C-S-H) in the hardened Portland cement paste (which is the binder of mineral aggregates), is fundamentally different from the creep of metals and polymers. Unlike the creep of metals, it occurs at all Stress (mechanics), stress levels and, within the service stress range, is linearly dependent on the stress if the pore water content is constant. Unlike the creep of polymers and metals, it exhibits multi-months aging, caused by chemical hardening due to Hydrate, hydration which stiffens the microstructure, and multi-year aging, caused by long-term relaxation of self-equilibrated micro-stresses in the nano-porous microstructure of the C-S-H. If concrete is fully dried, it does not creep, but it is next to impossible to dry concrete fully without severe cracking. Changes of pore water content due to drying or wetti ...

Shrinkage (fabric)
Dimensional stability (in fabric) pertains to a fabric's ability to maintain its initial size and shape even after undergoing wear and care, which is a desirable property. Textile manufacturing is based on the conversion of fiber into yarn, yarn into fabric, includes spinning, weaving, or knitting, etc. The fabric passes through many inevitable changes and mechanical forces during this journey. When the products are immersed in water, the water acts as a relaxing medium, and all stresses and strains are relaxed and the fabric tries to come back to its original state. The more dimensionally stable a fabric is, the less it is subject to shrinkage. Shrinkage is the change of dimensions in textile products when they are washed or relaxed. The change is always expressed relative to the dimensions before the exposure of washing or relaxing. Shrinkage is also called residual shrinkage and measured in percentage. The major cause of shrinkage is the release of stresses and strains intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood Drying
Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air drying is the more traditional method. There are two main reasons for drying wood: ; Woodworking:When wood is used as a construction material, whether as a structural support in a building or in woodworking objects, it will absorb or expel moisture until it is in equilibrium with its surroundings. Equilibration (usually drying) causes unequal shrinkage in the wood, and can cause damage to the wood if equilibration occurs too rapidly. The equilibration must be controlled to prevent damage to the wood. ; Wood burning: When wood is burned (firewood), it is usually best to dry it first. Damage from shrinkage is not a problem here, as it may be in the case of drying for woodworking purposes. Moisture affects the burning process, with unburnt hydrocarbons going up the chimney. If a 5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrinkage (accounting)
In accounting, shrinkage or shrink occurs when a retailer has fewer items in stock than were expected by the inventory list. This can be caused by clerical error, or from goods being damaged, lost, or stolen between the point of manufacture (or purchase from a supplier) and the point of sale. High shrinkage can adversely affect a retailer's profit. In 2008, the retail industry in the United States experienced shrinkage rates of around 1.52% of sales.''National Retail Security Survey'' (2009) University of Florida During the same year, retailers in Europe and Asia Pacific reported average shrinkage of about 1.27% and 1.20% of sales, respectively.''Global Retail Theft Barometer 2008'' Causes According to the 2008 National Retail Security Survey conducted at the University of Florida, a shrinkage rate of 1.51% translates to $36.3 billion in annual loss ($15.5 billion to employee theft and $12.9 billion to shoplifters). Theft, both internal and external to the com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casting Defect
A casting defect is an undesired irregularity in a metal casting process. Some defects can be tolerated while others can be repaired, otherwise they must be eliminated. They are broken down into five main categories: ''gas porosity'', ''shrinkage defects'', ''mould material defects'', ''pouring metal defects'', and ''metallurgical defects''. Terminology The terms "defect" and "" refer to two specific and separate things in castings. Defects are defined as conditions in a casting that must be corrected or removed, or the casting must be rejected. Discontinuities, also known as "imperfections", are defined as "interruptions in the physical continuity of the casting". Therefore, if the casting is less than perfect, but still useful and in tolerance, the imperfections should be deemed "discontinuities". Types There are many types of defects which result from many different causes. Some of the solutions to certain defects can be the cause for another type of defect. The following def ...

Shrinkage (statistics)
In statistics, shrinkage is the reduction in the effects of sampling variation. In regression analysis, a fitted relationship appears to perform less well on a new data set than on the data set used for fitting. In particular the value of the coefficient of determination 'shrinks'. This idea is complementary to overfitting and, separately, to the standard adjustment made in the coefficient of determination to compensate for the subjective effects of further sampling, like controlling for the potential of new explanatory terms improving the model by chance: that is, the adjustment formula itself provides "shrinkage." But the adjustment formula yields an artificial shrinkage. A shrinkage estimator is an estimator that, either explicitly or implicitly, incorporates the effects of shrinkage. In loose terms this means that a naive or raw estimate is improved by combining it with other information. The term relates to the notion that the improved estimate is made closer to the value supp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrinkage (slang)
Human penis size varies on a number of measures, including length and circumference when Flaccid penis, flaccid and erect penis, erect. Besides the natural variability of human penises in general, there are factors that lead to minor variations in a particular male, such as the level of sexual arousal, arousal, time of day, ambient temperature, anxiety level, physical activity, and frequency of sexual activity. Compared to other primates, including large examples such as the gorilla, the human penis is thickest, both in absolute terms and relative to the rest of the body. Most human penis growth occurs in two stages: the first between infancy and the age of five; and then between about one year after the onset of puberty and, at the latest, approximately 17 years of age. Measurements vary, with studies that rely on self-measurement reporting a significantly higher average than those with a health professional measuring.

Degrowth
Degrowth is an Academic research, academic and social Social movement, movement critical of the concept of economic growth, growth in Real gross domestic product, gross domestic product as a measure of Human development (economics), human and economic development. The idea of degrowth is based on ideas and research from economic anthropology, ecological economics, environmental sciences, and development studies. It argues that modern capitalism's unitary focus on growth causes widespread Environmental degradation, ecological damage and is unnecessary for the further increase of Standard of living, human living standards. Degrowth theory has been met with both academic acclaim and considerable criticism. Degrowth's main argument is that an infinite expansion of the economy is fundamentally contradictory to the Resource depletion, finiteness of material resources on Earth. It argues that economic growth measured by GDP should be abandoned as a policy objective. Policy should instead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Miniaturization
Miniaturization ( Br.Eng.: ''miniaturisation'') is the trend to manufacture ever-smaller mechanical, optical, and electronic products and devices. Examples include miniaturization of mobile phones, computers and vehicle engine downsizing. In electronics, the exponential scaling and miniaturization of silicon MOSFETs (MOS transistors) leads to the number of transistors on an integrated circuit chip doubling every two years, an observation known as Moore's law. This leads to MOS integrated circuits such as microprocessors and memory chips being built with increasing transistor density, faster performance, and lower power consumption, enabling the miniaturization of electronic devices. Electronic circuits The history of miniaturization is associated with the history of information technology based on the succession of switching devices, each smaller, faster, and cheaper than its predecessor. During the period referred to as the Second Industrial Revolution (), miniaturizati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
