Volumetric specific storage (or volume specific storage) is the volume of water that an aquifer releases from storage, per volume of aquifer, per unit decline in hydraulic head (Freeze and Cherry, 1979): where is the volumetric specific storage ; is the bulk volume of that portion of the aquifer from which the water is released ; is the volume of water released from storage ; is the decline in pressure (N•m-2 or ) ; is the decline in hydraulic head and is the specific weight of water (N•m-3 or )... In hydrogeology, volumetric specific storage is much more commonly encountered than mass specific storage...

Holography ... The holographic recording itself is not a plain image – it consists of an apparently random structure of either varying intensity, density or profile. Overview and history The Hungarian-British physicist Dennis Gabor (Hungarian name: Gábor Dénes), was awarded the Nobel Prize in Physics in 1971 for "for his invention and development of the holographic method"...
Food Storage ... Food storage safety Freezers and thawing food Freezer temperature should be maintained at 0°F and below... The United States Department of Agriculture, Food Safety and Inspection Service publishes a chart showing the suggested freezer storage time for common foods... Refrigeration It is important to note that safe food storage using refrigeration requires adhering to temperature guidelines: For safety, it is important to verify the temperature of the refrigerator...
Character Encoding ... Morse code was introduced in the 1840s and is used to encode each letter of the Latin alphabet and each Arabic numeral as a series of long and short presses of a telegraph key. Representations of characters encoded using Morse code varied in length...
Grid Computing ... Grid size can vary by a considerable amount. Grids are a form of distributed computing whereby a “super virtual computer” is composed of many networked loosely coupled computers acting together to perform very large tasks...
Database ... The term database is correctly applied to the data and their supporting data structures, and not to the database management system (DBMS). The database data collection with DBMS is called a database system...
List Of Google's Hoaxes And Easter Eggs ... This hoax was probably intended as a parody of Google's then invite-only email service called Gmail. Although ostensibly free, the company claimed the beverage could only be obtained by returning the cap of a Google Gulp bottle to a local grocery store: a causal loop...
Camera ... Cameras may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A camera generally consists of an enclosed hollow with an opening (aperture) at one end for light to enter, and a recording or viewing surface for capturing the light at the other end...
Computer Network ... Networks may be classified according to a wide variety of characteristics such as the medium used to transport the data, communications protocol used, scale, topology, and organizational scope. Communications protocols define the rules and data formats for exchanging information in a computer network, and provide the basis for network programming...
Warehouse ... Pallets and product move on a system of automated conveyors, cranes and automated storage and retrieval systems coordinated by programmable logic controllers and computers running logistics automation software... These systems are often installed in refrigerated warehouses where temperatures are kept very cold to keep product from spoiling, especially in electronics warehouse where they require specific temperature to avoid damaging the parts, and also where land is expensive, as automated storage systems can use vertical space efficiently... These high-bay storage areas are often more than 10 meters (33 feet) high, with some over 20 meters (65 feet) high...
Water ... Water covers 70.9% of the Earth's surface, and is vital for all known forms of life. On Earth, 96.5% of the planet's water is found in oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies, and 0.001% in the air as vapor, clouds (formed of solid and liquid water particles suspended in air), and precipitation...
