Shelf (storage)
A shelf ( : shelves) is a flat, horizontal plane used for items that are displayed or stored in a home, business, store, or elsewhere. It is raised off the floor and often anchored to a wall, supported on its shorter length sides by brackets, or otherwise anchored to cabinetry by brackets, dowels, screws, or nails. It can also be held up by columns or pillars. A shelf is also known as a ''counter'', ''ledge'', ''mantel'', or ''rack''. Tables designed to be placed against a wall, possibly mounted, are known as console tables, and are similar to individual shelves. A shelf can be attached to a wall or other vertical surface, be suspended from a ceiling, be a part of a free-standing frame unit, or it can be part of a piece of furniture such as a cabinet, bookcase, entertainment center, headboard, and so on. Usually, two to six shelves make up a unit, each shelf being attached perpendicularly to the vertical or diagonal supports and positioned parallel one above the other. Free-st ...

Continental Shelf
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an ''insular shelf''. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf. Under the United Nations Convention on the Law of the Sea, the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the shores of a par ...

Ice Shelf
An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. The thickness of ice shelves can range from about to . In contrast, sea ice is formed on water, is much thinner (typically less than ), and forms throughout the Arctic Ocean. It is also found in the Southern Ocean around the continent of Antarctica. The movement of ice shelves is principally driven by gravity-induced pressure from the grounded ice. That flow continually moves ice from the grounding line to the seaward front of the shelf. In steady state, about half of Antarctica's ice shelf mass is lost to basal melt and half is lost to calving, but the relative importance of each process varies significantly between ice s ...

Shelf, West Yorkshire
Shelf is a village in Calderdale in West Yorkshire, England. The village is situated halfway, about , between Bradford and Halifax, on the A6036 road. In 2001 it had a population of 4,496. At the 2011 Census Shelf was measured as part of the Calderdale ward of Northowram and Shelf. History In the ''Domesday Book'' the village is called "Scelf." The place name probably derives from the Anglo Saxon word 'Scelf', suggesting a broad and level shelf of land. In the period before 1700 Shelf developed from a mixed moorland and forested landscape to a few scattered farmsteads; to a landscape full of activity. Shelf gained a number of mills and workers cottages during the Industrial Revolution, and there are a number of historical relics including a stone horse trough and a stone chair milestone originally erected in 1737 which gave rise to the local area being named Stone Chair, Shelf. Prior to 1851, Shelf was a part of the large Parish of Halifax. The Parish Church of Shelf St. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shelf Corporation
A shelf corporation, shelf company, or aged corporation is a company or corporation that has had no activity. It was created and left with no activity – metaphorically put on the "shelf" to "age". The company can then be sold to a person or group of persons who wish to start a company without going through all the procedures of creating a new one. Reasons for buying Common reasons for buying a shelf corporation include: * To save the time involved in taking the steps to create a new corporation. * To gain the opportunity to bid on contracts. Some jurisdictions require that a company be in business for a certain length of time to have this ability. * To show corporate longevity in order to attract consumers or investors. * To gain access to corporate credit. These reasons are open to criticism. Many years ago, it would take months to properly incorporate a business. However, it is now quite easy, at least in Australia, Canada, the United States, Western Europe and Dubai, to d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shelf (organization)
Shelf is a voluntary organisation created with the aim of bringing new levels of sexual health awareness to young people of the United Kingdom. It is unique in that it was founded by four Year 10 students of Peterborough in April 2007 and is still currently owned and operated by them. It was founded with support from members of Peterborough City Council and the Peterborough NHS Primary Care Trust. Shelf runs via a website and distributed brochures containing information on sexual health and links to local support organisations. History Shelf was originally created as a business idea to be entered into "The Big Deal", a national business and enterprise challenge run by the National Academy for Gifted and Talented Youth (NAGTY). The competition ran over 10 weeks, and required groups of students (aided by a mentor) to produce a business idea by completing weekly tasks. Over 30 groups entered the competition and then presented their ideas to a panel of judges, in the style of the B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Shelf
A light shelf is a horizontal surface that reflects daylight deep into a building. Light shelves are placed above eye-level and have high-reflectance upper surfaces, which reflect daylight onto the ceiling and deeper into the space. Light shelves are typically used in high-rise and low-rise office buildings, as well as institutional buildings. This design is generally used on the equator-facing side of the building, which is where maximum sunlight is found, and as a result is most effective. Not only do light shelves allow light to penetrate through the building, they are also designed to shade near the windows, due to the overhang of the shelf, and help reduce window glare. Exterior shelves are generally more effective shading devices than interior shelves. A combination of exterior and interior shelves will work best in providing an even illumination gradient. Benefits Architectural light shelves have been proven to reduce the need for artificial lighting in buildings. Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shelf (computing)
The Shelf is an interface feature in NeXTSTEP and OpenStep, OPENSTEP, and is used as a repository to store links to commonly used files, directories and programs, and as a temporary "holding" place to move/copy files and directories around in the file system hierarchy. In macOS, items may be dragged onto the sidebar area of the Finder (software), Finder, but these do not behave as placeholders and cannot be manipulated in the below manner. The dynamics of the Shelf in file system operations can be illustrated by comparison with the metaphor used in the Microsoft Windows operating systems. In order to move a file the following steps may be taken: * the window containing the source folder is opened * the window containing the destination folder is opened * the desired file in the source directory is dragged to the destination folder With the NeXT operating systems, in addition to moving files by dragging them from window to window, the following method can be used: * the user naviga ...

Shelf Life
Shelf life is the length of time that a commodity may be stored without becoming unfit for use, consumption, or sale. In other words, it might refer to whether a commodity should no longer be on a pantry shelf (unfit for use), or no longer on a supermarket shelf (unfit for sale, but not yet unfit for use). It applies to cosmetics, foods and beverages, medical devices, medicines, explosives, pharmaceutical drugs, chemicals, tyres, batteries, and many other perishable items. In some regions, an advisory ''best before'', mandatory ''use by'' or ''freshness date'' is required on packaged perishable foods. The concept of expiration date is related but legally distinct in some jurisdictions. Background Shelf life is the recommended maximum time for which products or fresh (harvested) produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected (or specified) conditions of distribution, storage and display.

Shelf Registration
Shelf registration, shelf offering, or shelf prospectus is a type of public offering where certain issuers are allowed to offer and sell securities to the public without a separate prospectus for each act of offering and without the issue of further prospectus. Instead, there is a single prospectus for multiple, undefined future offerings. The prospectus (often as part of a registration statement) may be used to offer securities for up to several years after its publication. A shelf registration statement is a filing with the SEC to register a public offering, usually where there is no present intention to immediately sell all the securities being registered. A shelf registration statement permits multiple offerings based on the same registration. Shelf registration is mostly used for sales of new securities by the issuer (primary offerings), although it might possibly be used for resales of outstanding securities (secondary offerings) or a combination of both. For example, a compan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulphur Shelf
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetal In chemistry, a nonmetal is a chemical element that generally lacks a predominance of metallic properties; they range from colorless gases (like hydrogen) to shiny solids (like carbon, as graphite). The electrons in nonmetals behave differentl ...lic. Under standard conditions for temperature and pressure, normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula octasulfur, S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native element minerals, native form, sulfur on Earth usually occurs as sulfide minerals, sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
