The Vacuum is a free bi monthly newspaper published in Belfast , Northern Ireland by the arts organisation Factotum arts organisation Factotum . Each issue is themed and contains critical commentary about the city and broader cultural issues. 15,000 copies of the paper are produced and distributed in bar, cafes and other public spaces. The paper was first published in January 2003.

These themes can be open ended such as in the Fantasy issue when contributors were simply asked to describe one of their fantasies or more specific such as the Nostalgia issue which contained articles on Troubles Nostalgia and Marketing Nostalgia . Most issues contain a range of writing from social commentary, through satire to farce, focused on one area of discussion. Rarely does The Vacuum avoid controversy, no matter what its chosen issue.

Unreferenced stub auto yes date December 2009 Distinguish Manifold vacuum For the type of laboratory glassware Schlenk line In quantum field theory , the vacuum state may be degenerate . Each pure vacuum state generates its own superselection sector . The space of all pure vacuum states often has a manifold structure and is called the vacuum manifold . Vacuum manifolds arise during the process of spontaneous symmetry breaking from a group G to a subgroup H and the corresponding vacuum manifold has to be a realization of G and contain the quotient space G H. In many cases, it would simply be G H, although it could be larger. Not all vacuum manifolds arise due to spontaneous symmetry breaking. Supersymmetric models often contain moduli space s which is another name for the vacuum manifold. In many cases, the vacuum manifold is parameterized by the values of permissible vacuum expectation value s. This is not the case for spontaneous symmetry breaking due to fermion condensate fermion condensation , though. If the vacuum manifold is homotopy homotopically nontrivial, it s possible for there to be topological sector s.

A Vacuum Table consists of a typically flat rigid surface in which exists small holes or channels in which to evacuate air from under a workpiece, as to apply varying vacuum ... commonly used machine in a machine shop environment. The main purpose of the Vacuum Table is to allow full access to all sides of a machined part, except the side in which the part contacts Vacuum Table. A Vacuum Table is similar to a Magnetic Clamping Table in use, typically, to the same end as a Vacuum Table except instead of vacuum, the Magnetic Table uses electro magnetic attraction to restrain ferrous materials to the table facilitating ease of access for modern machining.

Air dams are not entirely required in the use of a Vacuum Table but they can be when the source of vacuum is limited. As a vacuum pump, generally, is designed for high vacuum as opposed to high volume, air dams can be used, again, to increase clamping force.

A person is placed in a latex envelope spanned by a frame and a suction pump or floor vacuum removes most of the air in the envelope. The frame can be either a simple rectangle of pierced pvc pipes, joined by pvc joints, or three dimensional frames of various sizes, with a similar pvc construction. There are several ways that the vacuum bed can be designed to facilitate breathing. The most common is a tube running from outside of the vacuum bed into the person s mouth. A second option is a reinforced hole that is positioned so that the mouth protrudes. A third option is a reinforced gasket through which one forces the entire head. Incorporating a related fetish, some vacuum beds use a gas mask to facilitate respiration. The vacuum bed is both a bondage and sensation device. The user is unable to move significantly although some wiggling is possible , and is unable to speak or see, depending on the breathing hole used. In addition, though, the sensation of the vacuum bed itself, as well as any other play stroking, percussion, vibrations are quite pleasurable, and some are much more intense than what would be experienced without the vacuum bed. The vacuum bed must be used with the aid of another person, as the user cannot control the vacuum itself, nor escape the vacuum bed unaided. References Margot D.

Vacuum consolidation or vacuum preloading is a soft soil improvement method that has been successfully used by geotechnical engineers and specialist sof ground improvement companies in countries such as Australia, China, Korea, Thailand and France for soil improvement or land reclamation Chu et al., 2005 . It does not necessarily require surcharge fill and vacuum loads of 80kPa or greater can, typically, be maintained for as long as required. However, if loads of 80kPa or greater are needed in order to achieve the target soil improvement, additional surcharge may be placed on top of the vacuum system. The vacuum preloading method is cheaper and faster than the fill surcharge method for an equivalent load in suitable areas. Where the underlying ground consists of permeable materials, such as sand or sandy clay, the cost of the technique will be significantly increased due to the requirement of cut off walls into non permeable layers to seal off the vacuum. It has been suggested by Carter et al. 2005 that the settlement resulting from vacuum preloading is less than that from a surcharge load of the same magnitude as vacuum consolidation is influenced by drainage boundary conditions.
