Closures are typically implemented with a special data structure that contains a pointer to the function code, plus a representation of the function's lexical environment ( e. g., the set of available variables and their values ) at the time when the closure was created.

Closures are one of the core tools of functional programming, and many languages support at least this degree of functional programming.

Closures and mergers during the mid-20th century reduced the number of breweries to two and by 1999 only one remained, The Forth Brewery which became Williams Bros. in 2003.

Closures are expressed naturally in Scheme.

Closures are closely related to Actors in the Actor model of concurrent computation where the values in the function's lexical environment are called acquaintances.

Closures are closely related to function objects ; the transformation from the former to the latter is known as defunctionalization or lambda lifting.

Closures are devices and techniques used to close or seal a bottle, jug, jar, tube, can, etc.

Closures in all coalfields began in the 1980s as demand for British coal was weakened by large subsidies that other European governments gave to their coal industries ( West Germany subsidised coal by four times as much and France by three times as much in 1984 ) and the availability of lower cost, often open-cast, coal mined in Australia, Colombia, Poland and the United States.

Closures were as follows :- Direct service to Franeker in October 1933 ; Direct service to Harlingen in May 1935 and freight in January 1938 ; All other passenger services ceased in July 1936, but were reopened as far as Tzummarum and Dokkum-Aalsum in May 1940.

Closures of such small-scale loss-making lines made little difference to the overall deficit.

A wide network of several hundred miners ' support groups were set up, often led by miners ' " wives and girlfriends groups ", such as Women Against Pit Closures.

Closures must be applied tight enough to maintain a seal and to resist closure back-off, but must be not be applied so tightly that the end user cannot remove the closure.

Closures can be a cap, cover, lid, plug, etc.

* History of Closures from the CCMA website

The Corticeira Amorim ’ s study, in particular (" Analysis of the life cycle of Cork, Aluminum and Plastic Wine Closures "), was developed by PricewaterhouseCoopers, according to ISO 14040.

The study " Analysis of the life cycle of Cork, Aluminum and Plastic Wine Closures ," commissioned by cork manufacturer Amorim and made public in December 2008, concluded that cork is the most environmentally responsible stopper, in a one-year life cycle analysis comparison with the plastic stoppers and aluminum screw caps.

Closures in this period included: the Charnwood Forest Railway, closed to passengers in 1931, the Harborne Line in Birmingham, closed to passengers in 1934, and the Midland and Great Northern Joint Railway, closed in 1959.

Closures continued in the 1960s with, for example, the Parkside, Fountains, Malvern and Pioneer Mills shutting in 1964.

Despite widespread support, including alliances forged with students and the prominent role of many miners ' wives in Women Against Pit Closures, the strike was eventually lost.

Its operating groups include Magna Steyr, Magna Powertrain, Magna Exteriors and Interiors, Magna Seating, Magna Closures, Magna Mirrors, Magna Electronics and Cosma International.

Closures in excess of 1000ms were defined as microsleeps.

An Empirical and Analytic Study of Stack vs. Heap Cost for Languages with Closures.

Through subsidiary, Inteva Products, LLC, Renco Group purchased Delphi's Global Interiors and Closures businesses in March 2008.

Closures were originally concentrated in Scotland, but then moved into North East England, Lancashire, and South Wales in the 1970s.

When Ares does appear in myths, he typically faces humiliation.

A colloidal crystal is a highly ordered array of particles that can be formed over a very long range ( typically on the order of a few millimeters to one centimeter ) and that appear analogous to their atomic or molecular counterparts.

Today, crannogs typically appear as small, circular islets, often in diameter, covered in dense vegetation due to their inaccessibility to grazing livestock.

Clicks appear more stop-like ( sharp / abrupt ) or affricate-like ( noisy ) depending on their place of articulation: In southern Africa, clicks involving an apical alveolar or laminal postalveolar closure are acoustically abrupt and sharp, like stops, while labial, dental, and lateral clicks typically have longer and acoustically noisier releases that are superficially more like affricates.

Decision problems typically appear in mathematical questions of decidability, that is, the question of the existence of an effective method to determine the existence of some object or its membership in a set ; many of the important problems in mathematics are undecidable.

Okurigana are kana that appear inline at normal size following kanji stems, typically to complete and to inflect adjectives and verbs.

In so far as those who donate organs are often impoverished and those who can afford black market organs are typically well-off, it would appear that there is an imbalance in the trade.

In mountainous areas ( or near rivers in mountainous areas ), the main aquifers are typically unconsolidated alluvium, composed of mostly horizontal layers of materials deposited by water processes ( rivers and streams ), which in cross-section ( looking at a two-dimensional slice of the aquifer ) appear to be layers of alternating coarse and fine materials.

On the day of the Academy Award ceremony, Ebert and Roeper typically appear on the live pre-awards show, An Evening at the Academy Awards: The Arrivals.

From a data forwarding and network topology perspective, this router functionality is typically kept distinct from the cable modem functionality ( at least logically ) even though the two may share a single enclosure and appear as one unit, sometimes called a residential gateway.

The transform may be normalised in other ways, in which case constant scaling factors ( typically or ) will appear in the relationships above.

Most caucasoid-like Vulcans ( a majority of those shown throughout the series ' runs ) typically appear with a subtle greenish hue to their skin, due to Vulcans ' copper-based blood, which is green in color.

The term " supernatural " is often used interchangeably with paranormal or preternatural — the latter typically limited to an adjective for describing abilities which appear to exceed the bounds of possibility.

Clinical symptoms typically appear within 30 minutes, but may take up to two hours, depending on other foods and activities.

ELVES often appear as dim, flattened, circular in the horizontal plane, expanding glows around in diameter that last for, typically, just one millisecond.

These cocci are facultatively intracellular and typically appear in pairs ( diplococci ), in the shape of coffee beans.

The tests are typically ordered if the symptoms do not resolve after a few weeks of treatment, or when they first appear in a person who is over age 45 or who has other symptoms such as weight loss, because stomach cancer can cause similar symptoms.
