Adit

An adit (from Latin aditus, entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins.

Construction

Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in this case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining.

Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advantages.

491 Gallery

The 491 Gallery was a squatted social centre and multi-disciplinary gallery in Leytonstone, London, England, that operated from 2001 to 2013. Taking its name from its street number, 491 Grove Green Road, the former factory was home to a community-led art organisation and served as an exhibition space for a diverse range of artists of different origins working in varied media. It contained a range of art and music studios, which were used to host workshops, classes and musical rehearsals.

Origin

The building, originally a factory, was later used as a storage space and warehouse for materials being used to construct the A12 that cuts through Leytonstone and the surrounding areas. Unlike the rest of the surrounding buildings, it and the few neighbouring houses were not subject to compulsory purchase orders and demolition for the A12 site. When in late 2000 the building was abandoned, it became occupied by a group of homeless drug users, who remained in it for some six months. Within a month of their vacating the premises, the building was reoccupied by a group of artists, who spent the next several years turning it into a community space. The neighbouring building, formerly houses, was also occupied, and named Vertigo, after the film by Alfred Hitchcock, a famous resident of Leytonstone.

Private (rocket)

Private was an experimental rocket developed by the California Institute of Technology on behalf of the United States Army. Tested in two different configurations, it provided the proof of concept that a fin-stabilised ballistic missile was technologically feasible, and led to the development of the Corporal ballistic missile.

History

The Private program was begun in 1944 as an outgrowth of work by the California Institute of Technology's Guggenheim Aeronautical Laboratory that had produced the first practical jet-assisted take-off (JATO) rockets. A proposal to adapt the JATO rockets for research into the development of ballistic missiles was accepted, and the first flight of the Private A rocket, developed under the direction of Tsien Hsue-shen, took place in December 1944, conducted at Camp Irwin in California.

Private A was an unguided, fin-stabilised ballistic rocket; it consisted of a JATO unit equipped with cruciform tail fins, and a set of four T22 booster rockets that were jettisoned after launch. This made Private A the first multistage rocket to be flown in the United States.

Information hiding

In computer science, information hiding is the principle of segregation of the design decisions in a computer program that are most likely to change, thus protecting other parts of the program from extensive modification if the design decision is changed. The protection involves providing a stable interface which protects the remainder of the program from the implementation (the details that are most likely to change).

Written another way, information hiding is the ability to prevent certain aspects of a class or software component from being accessible to its clients, using either programming language features (like private variables) or an explicit exporting policy.

Overview

The term encapsulation is often used interchangeably with information hiding. Not all agree on the distinctions between the two though; one may think of information hiding as being the principle and encapsulation being the technique. A software module hides information by encapsulating the information into a module or other construct which presents an interface.

Private (web series)

Private is an American Web series produced by Alloy Entertainment based on the novels of the same name by Kate Brian.

The series was announced in May 2009, beginning with a contest allowing female readers the chance to audition for the role of Kiran Hayes. It was also announced that the series would adapt the first four books via 20 episodes, each with a standard length of four to six minutes.

A DVD with episodes of the series was released by Newvideo.

Contest

Private: The Casting Call was the contest in which three contestants competed for the role of Kiran Hayes in the Web adaptation of Private.
