Cerebrospinal Fluid
Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates. CSF is produced by specialised ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations. There is about 125 mL of CSF at any one time, and about 500 mL is generated every day. CSF acts as a shock absorber, cushion or buffer, providing basic mechanical and immunological protection to the brain inside the skull. CSF also serves a vital function in the cerebral autoregulation of cerebral blood flow. CSF occupies the subarachnoid space (between the arachnoid mater and the pia mater) and the ventricular system around and inside the brain and spinal cord. It fills the ventricles of the brain, cisterns, and sulci, as well as the central canal of the spinal cord. There is also a connection from the subarachnoid space to the bony labyrinth of the inner ear via the perilymphat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NIST Cybersecurity Framework
NIST Cybersecurity Framework is a set of guidelines for mitigating organizational cybersecurity risks, published by the US National Institute of Standards and Technology (NIST) based on existing standards, guidelines, and practices. The framework "provides a high level taxonomy of cybersecurity outcomes and a methodology to assess and manage those outcomes", in addition to guidance on the protection of privacy and civil liberties in a cybersecurity context. It has been translated to many languages, and is used by several governments and a wide range of businesses and organizations. A 2016 study found that 70% of organizations surveyed see the NIST Cybersecurity Framework as a popular best practice for computer security, but many note that it requires significant investment. Overview The NIST Cybersecurity Framework is designed for individual businesses and other organizations to assess risks they face. Version 1.0 was published by the US National Institute of Standards and Tec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Configuration State Function
In quantum chemistry, a configuration state function (CSF), is a symmetry-adapted linear combination of Slater determinants. A CSF must not be confused with a configuration. In general, one configuration gives rise to several CSFs; all have the same total quantum numbers for spin and spatial parts but differ in their intermediate couplings. Definition A configuration state function (CSF), is a symmetry-adapted linear combination of Slater determinants. It is constructed to have the same quantum numbers as the wavefunction, \Psi, of the system being studied. In the method of configuration interaction, the wavefunction can be expressed as a linear combination of CSFs, that is in the form \Psi = \sum_k c_k \psi_k where \psi_k denotes the set of CSFs. The coefficients, c_k, are found by using the expansion of \Psi to compute a Hamiltonian matrix. When this is diagonalized, the eigenvectors are chosen as the expansion coefficients. CSFs rather than just Slater determinants can also b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Community-supported Fishery
A community-supported fishery (CSF) is an alternative business model for selling fresh, locally sourced seafood. CSF programs, modeled after increasingly popular community-supported agriculture programs, offer members weekly shares of fresh seafood for a pre-paid membership fee. The first CSF program was started in Port Clyde, Maine, in 2007, and similar CSF programs have since been started across the United States and in Europe. Community supported fisheries aim to promote a positive relationship between fishermen, consumers, and the ocean by providing high-quality, locally caught seafood to members. CSF programs began as a method to help marine ecosystems recover from the effects of overfishing while maintaining a thriving fishing community. Structure In a CSF, consumers sign up as members and pay in advance for a "share" of seafood, to be delivered weekly. Generally, each share is measured by weight but the size of shares offered varies among programs. Many programs offer multiple ...

Compagnie Générale De La Télégraphie Sans Fil
The Compagnie générale de la télégraphie sans fil (CSF: General Wireless Telegraphy Company) was a French company founded in 1918 during a reorganization and expansion of the Société française radio-électrique (SFR), which became a subsidiary. The company developed technology for radio-telegraphy, radio program transmission, radar, television and other applications. It provided broadcasting and telegraphy services, and sold its equipment throughout the French colonial empire and in many other parts of the world. In 1968 CSF merged with the Thomson-Brandt to form Thomson-CSF. Background From the mid-19th century the world was connected with an increasingly dense network of telegraph wires and submarine cables. In 1887 Heinrich Hertz of Germany conclusively proved the existence of electromagnetic waves. Alexander Stepanovich Popov of Russia developed antennas to transmit and receive radio waves. Scientists such as Édouard Branly and Nikola Tesla also contributed to developme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Community Of St
A community is a social unit (a group of living things) with commonality such as place, norms, religion, values, customs, or identity. Communities may share a sense of place situated in a given geographical area (e.g. a country, village, town, or neighbourhood) or in virtual space through communication platforms. Durable good relations that extend beyond immediate genealogical ties also define a sense of community, important to their identity, practice, and roles in social institutions such as family, home, work, government, society, or humanity at large. Although communities are usually small relative to personal social ties, "community" may also refer to large group affiliations such as national communities, international communities, and virtual communities. The English-language word "community" derives from the Old French ''comuneté'' (Modern French: ''communauté''), which comes from the Latin ''communitas'' "community", "public spirit" (from Latin ''communis'', "commo ...

Capsize Screening Formula
The capsize screening formula (CSF) is a controversial method of establishing the ability of boats to resist capsizing. It is defined for sailboats as: Beam / ((Displacement/64.2)1/3), with Displacement measured in pounds, and Beam in feet. A lower figure supposedly indicates greater stability, however the calculation does not consider factors such as hull shape or ballast. Background The formula came into being after the 1979 Fastnet race in England where a storm shredded the race fleet. The Cruising Club of America (CCA) put together a technical committee that analyzed race boat data. They came up with the formula to compare boats based on readily available data. The CCA characterizes the formula as "rough". A lower value is supposed to indicate a sailboat is less likely to capsize. A value of 2 is taken as a cutoff for acceptable to certain race committees. However this is an arbitrary cutoff based on the performance of boats in the 1979 Fastnet race. The CSF does not consid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caesium Fluoride
Caesium fluoride or cesium fluoride is an inorganic compound with the formula CsF and it is a hygroscopic white salt. Caesium fluoride can be used in organic synthesis as a source of the fluoride anion. Caesium also has the highest electropositivity of all non-radioactive elements and fluorine has the highest electronegativity of all known elements. Synthesis and properties Caesium fluoride can be prepared by the reaction of caesium hydroxide (CsOH) with hydrofluoric acid (HF) and the resulting salt can then be purified by recrystallization. The reaction is shown below: :CsOH + HF → CsF + H2O Using the same reaction, another way to create caesium fluoride is to treat caesium carbonate (Cs2CO3) with hydrofluoric acid and again, the resulting salt can then be purified by recrystallization. The reaction is shown below: :Cs2CO3 + 2 HF → 2 CsF + H2O + CO2 CsF is more soluble than sodium fluoride or potassium fluoride in organic solvents. It is available in its anhydrous for ...
