Quenching

In materials science, quenching, a type of heat treating, is the rapid cooling of a workpiece to obtain certain material properties. It prevents low-temperature processes, such as phase transformations, from occurring by only providing a narrow window of time in which the reaction is both thermodynamically favorable and kinetically accessible. For instance, it can reduce crystallinity and thereby increase the hardness of both alloys and plastics (produced through polymerization).

In metallurgy, it is most commonly used to harden steel by introducing martensite, in which case the steel must be rapidly cooled through its eutectoid point, the temperature at which austenite becomes unstable. In steel alloyed with metals such as nickel and manganese, the eutectoid temperature becomes much lower, but the kinetic barriers to phase transformation remain the same. This allows quenching to start at a lower temperature, making the process much easier. High speed steel also has added tungsten, which serves to raise kinetic barriers and give the illusion that the material has been cooled more rapidly than it really has. Even cooling such alloys slowly in air has most of the desired effects of quenching.

Quench (company)

Products Description

Filtered water systems are plumbed into a building's water supply and purified at the last possible point before consumption. Filter water coolers and ice dispensers typically use carbon filtration, UV water disinfection and/or reverse osmosis to purify drinking water.

Acquisitions

In March 2012, Quench purchased Aqua Perfect of Arizona LLC. In July of 2105 Quench acquired Region-X LLC a Massachuetts company that provides services related to high purity water systems

Quench (album)

Quench released in the UK on 17 October 1998 is The Beautiful South's sixth original album. Including the compilation Carry On Up The Charts it was the band's third album in a row to reach the top of the charts.

The cover depicts a boxer by Scottish painter Peter Howson. Commissioned for the album, the original painting can be seen in the Ferens Art Gallery, Hull. After the band cropped the image and used it in merchandise and promotional material, Howson took legal action against the band, receiving around £30,000 in damages. Whilst the first two singles from the album also have artwork by Howson, "How Long's a Tear Take to Dry?" and "The Table" do not.

Dyn

Dyn or DYN may refer to:

Dyn (company)

Dyn DNS Company (pronounced "dine") is an Internet performance management company, offering products to monitor, control, and optimize online infrastructure, and also domain registration services and email products.

History

Dyn was created as an open source, community-led student project by Jeremy Hitchcock, Tom Daly, Tim Wilde and Chris Reinhardt during their undergraduate studies at Worcester Polytechnic Institute. Originally, Dyn enabled students to access lab computers and print documents remotely. The project then moved towards domain name system (DNS) services. The first iteration was a free dynamic DNS service known as DynDNS. The project required $25,000 to stay open, and raised over $40,000.

The donation based model continued until a premium service called the DynECT Platform became available in 2008.

In 2011, Dyn opened an office in London, England - it eventually moved its EMEA headquarters to Brighton, UK. It was also in 2011 that Dyn opened its new Manchester, NH headquarters.

DYN (magazine)

DYN (derived from the Greek word κατὰ τὸ δυνατόν, that which is possible) was an art magazine founded by the Austrian-Mexican surrealist Wolfgang Paalen, published in Mexico City, and distributed in New York, Paris, and London between 1942 and 1944. Only six issues were produced.

Background

With his journal Paalen in his work as Editeur gave himself the opportunity to fully develop his intellectual abilities with the evident but nevertheless for himself surprising result that he temporarily advanced to one of the most influential art theorists during the war. In seven large essays and countless smaller articles and reviews he discussed in detail all current hot topics that also concerned the young artists in New York, and in response received their full attention: the new image as potential picture-being; morality, deliberated of Marxist means-end thinking; plastic automatism – deliberated of the bondage of preconceived literary contents; dialectical materialism – unmasked as rooted in nothing else than a cleverly exploited mental weakness; microphysics - as confirmation of the viewer-dependent, potential nature of all being; the flat and rhythmical canvases of cubism - as true origin of a new spatial adventure overcoming the painting as window; and over all the female Totem as a mantra for a dialogical self-expression. One of the main underlying notions of DYN was the attempt to reconcile diverging materialist and mystical tendencies in Surrealism with a new art-philosophy of contingency. Breton, however, reacted as deeply offended, and in the preface of VVV argued: "We reject the lie of an open surrealism, in which anything is possible".
