Hydraulic Fracturing
Fracking (also known as hydraulic fracturing, hydrofracturing, or hydrofracking) is a well stimulation technique involving the fracturing of bedrock formations by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open. Hydraulic fracturing began as an experiment in 1947, and the first commercially successful application followed in 1950. As of 2012, 2.5 million "frac jobs" had been performed worldwide on oil and gas wells, over one million of those within the U.S. Such treatment is generally necessary to achieve adequate flow rates in shale gas, tight gas, tig ...

Fonds Régional D'art Contemporain
A Fonds régional d'art contemporain (Frac) is a public regional collection of contemporary art set in one of the metropolitan or overseas regions of France. There are currently 23 Fracs across the country, organised into a national network called Platform since 2005. Fracs are funded by regions, by the state through the Ministry of Culture and by municipalities. Originally without venues, Fracs are now hosted in repurposed historical buildings, or in specifically-built art museums, depending on the size of their collection. Founding and history Fracs were founded by culture minister Jack Lang, as part of a decentralization policy to move aspects of governance out to regional governments. Starting in 1982, regional funds were set up to promote and encourage contemporary art by forming regional collections, and engaging in outreach to local communities and cultural institutions. The goals of the Frac program are: * To build a heritage of contemporary art in the region, and support ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Field Of Fractions
In abstract algebra, the field of fractions of an integral domain is the smallest field in which it can be embedded. The construction of the field of fractions is modeled on the relationship between the integral domain of integers and the field of rational numbers. Intuitively, it consists of ratios between integral domain elements. The field of fractions of R is sometimes denoted by \operatorname(R) or \operatorname(R), and the construction is sometimes also called the fraction field, field of quotients, or quotient field of R. All four are in common usage, but are not to be confused with the quotient of a ring by an ideal, which is a quite different concept. For a commutative ring which is not an integral domain, the analogous construction is called the localization or ring of quotients. Definition Given an integral domain and letting R^* = R \setminus \, we define an equivalence relation on R \times R^* by letting (n,d) \sim (m,b) whenever nb = md. We denote the equivale ...

FRAC Act
The Fracturing Responsibility and Awareness of Chemicals Act (, , dubbed as the FRAC Act) was a 2009 legislative proposal in the United States Congress to define hydraulic fracturing as a federally regulated activity under the Safe Drinking Water Act. The proposed act would have required the energy industry to disclose the chemical additives used in the hydraulic fracturing fluid. The gas industry opposed the legislation. The bill was introduced to both houses of the 111th United States Congress on June 9, 2009. The House bill was introduced by representatives Diana DeGette, D-Colo., Maurice Hinchey D-N.Y., and Jared Polis, D-Colo. The Senate version was introduced by senators Bob Casey, D-Pa., and Chuck Schumer, D-N.Y. The bill was re-introduced to both houses of the 112th United States Congress on March 15, 2011, by Representative Diana DeGette and Senator Bob Casey.

Fungicide Resistance Action Committee
Fungicides are biocidal chemical compounds or biological organisms used to kill parasitic fungi or their spores. A fungistatic inhibits their growth. Fungi can cause serious damage in agriculture, resulting in critical losses of yield, quality, and profit. Fungicides are used both in agriculture and to fight fungal infections in animals. Chemicals used to control oomycetes, which are not fungi, are also referred to as fungicides, as oomycetes use the same mechanisms as fungi to infect plants. Fungicides can either be contact, translaminar or systemic. Contact fungicides are not taken up into the plant tissue and protect only the plant where the spray is deposited. Translaminar fungicides redistribute the fungicide from the upper, sprayed leaf surface to the lower, unsprayed surface. Systemic fungicides are taken up and redistributed through the xylem vessels. Few fungicides move to all parts of a plant. Some are locally systemic, and some move upwardly. Most fungicides that can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frac Press
Omniscriptum Publishing Group, formerly known as VDM Verlag Dr. Müller, is a German publishing group headquartered in Riga, Latvia. Founded in 2002 in Düsseldorf, its book production is based on print-to-order technology. The company publishes theses, research notes, and dissertations through its e-commerce bookstores. Its publishing methods have been questioned for the soliciting of manuscripts from individuals, and for providing authors with the appearance of a peer-reviewed publishing history. OmniScriptum is designated as non-academic by the Norwegian Scientific Index, and its subsidiary Lambert Academic Publishing has been described as a predatory vanity press which does "not apply the basic standards of academic publishing such as peer-review, editorial or proof-reading processes." The company also offers print-to order publishing for fiction authors. It previously specialized in publishing and selling Wikipedia articles, but has stated that the practice of publishing ...

Coffee Service
Coffee service refers to the many and various styles in which coffee is made available to people, such as in restaurants and hotels. In particular, it sometimes refers to the set of dishes and vessels utilized to serve and consume coffee, akin to the notion of a tea service. Coffee service is also a catch-all term for services related to the delivery of coffee to employees of a business at low or no cost to them. Providing coffee to employees is popular among employers since employees will likely not leave the workplace to purchase coffee, subsequently reducing lost work time. Employers also see coffee service as a perk with a low cost. Coffee services Vending Some companies, with high traffic of visitors and employees, opt to install a coffee dispenser (vending machine) as their coffee service. Typically these machines give the user the choice of various types of coffee, tea and hot chocolate. Money collected is usually kept by the employer to offset the cost of the mainten ...

MOTM
MOTM is the name of the modular synthesizer system manufactured by Synthesis Technology. MOTM stands for "Mother Of The Modulars". History MOTM was created by Paul Schreiber in 1998. The system was created in part due to the renewed interest in large-format analog modular systems that occurred in the late 1990s. Production continues to this day, with over 8000 modules sold. The company, Synthesis Technology, also offers a limited number of modules in Eurorack and Frac format. Specifications MOTM systems use a ±15 volt power supply for most modules, with an additional 5 volt power supply required for some digital modules. Audio signals are the standard 10 volts, peak to peak. The MOTM system modules are all "5U" high (1U being 1.75 inches), and multiples of 1U wide. All 5U MOTM modules use 1/4-inch jacks for audio/CV signals. Euro and Frac modules use 3.5mm" (~1/8") jacks. MOTM modules can be mounted in a standard 19" rack using MOTM 19A rack rails, although many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Aircrewman
Aviation Warfare Operator is an enlisted rating of the U.S. Navy. It was previously designated as aviation anti-submarine warfare operator. However, under the CNO-directed "Helicopter Master Plan", all 78XX and 94XX aircrewmen were re-designated as "aviation warfare systems operators". The description of the Aviation Warfare Operator Rate (AW) on this page define only the "Active Duty" aspects of the AW rate, fleets (aircraft), positions, and duties that are manned by aircrew in today's Navy. The Full Time Support (FTS) and Selected Reserves (SELRES) components of the U.S. Naval Reserves make up the largest number of Aircrew in today's Navy. Many technologically advanced navies have a similar trade. Training All AWs must attain a minimum amount of education and training in several fields of science, technology, and aviation at several different schools. The educational "pipeline" averages 18 months to 2 years in length. The following list describes most of those schools: Sch ...
