Mačkovec pri Škocjanu

Mačkovec pri Škocjanu is a small settlement in the Municipality of Škocjan in southeastern Slovenia. Within th emunicipality, it belongs to the Village Community of Dole, it lies north of Škocjan, just off the road to Dolenje Dole. The municipality is now included in the Southeast Slovenia Statistical Region; the surname Hočevar is frequent in the village. Mačkovec pri Škocjanu is a clustered settlement on the west slope of Lapor Hill and east of Little Creek; the soil is sandy, with field areas named Zadnje njive, na Laporju, meadows in the Zadole area. There is wooded land to the northeast. Mačkovec pri Škocjanu was attested in written sources circa 1400 as Kaczendorff. Morphological evidence indicates that the name is not derived directly from maček'cat', but instead from Maček used as a nickname for an individual; the name is less to be derived from the noun mačkovec'pussy willow'. The name of the settlement was changed from Mačkovec to Mačkovec pri Škocjanu in 1953. Mačkovec pri Škocjanu at Geopedia

Nuclear reactor safety system

This article covers the technical aspects of active nuclear safety systems in the United States. For a general approach to nuclear safety, see nuclear safety; the three primary objectives of nuclear reactor safety systems as defined by the U. S. Nuclear Regulatory Commission are to shut down the reactor, maintain it in a shutdown condition and prevent the release of radioactive material. A reactor protection system is designed to terminate the nuclear reaction. By breaking the nuclear chain reaction, the source of heat is eliminated. Other systems can be used to remove decay heat from the core. All nuclear plants have some form of reactor protection system. Control rods are a series of rods that can be inserted into the reactor core to absorb neutrons and terminate the nuclear reaction, they are composed of actinides, transition metals, boron, in various alloys with structural backing such as steel. In addition to being neutron absorbent, the alloys used are required to have at least a low coefficient of thermal expansion so that they do not jam under high temperatures, they have to be self-lubricating metal on metal, because at the temperatures experienced by nuclear reactor cores oil lubrication would foul too quickly.

Boiling water reactors are able to SCRAM the reactor with the help of their control rods. In the case of a Loss of coolant accident, the water-loss of the primary cooling system can be compensated with normal water pumped into the cooling circuit. On the other hand, the standby liquid control system consists of a solution containing boric acid, which acts as a neutron poison and floods the core in case of problems with the stopping of the chain reaction. Pressurized water reactors can SCRAM the reactor with the help of their control rods. PWRs use boric acid to make fine adjustments to reactor power level, or reactivity, using their Chemical and Volume Control System. In the case of LOCA, PWRs have three sources of backup cooling water, high pressure injection, low pressure injection, core flood tanks, they all use water with a high concentration of boron. The essential service water system circulates the water that cools the plant's heat exchangers and other components before dissipating the heat into the environment.

Because this includes cooling the systems that remove decay heat from both the primary system and the spent fuel rod cooling ponds, the ESWS is a safety-critical system. Since the water is drawn from an adjacent river, the sea, or other large body of water, the system can be fouled by seaweed, marine organisms, oil pollution and debris. In locations without a large body of water in which to dissipate the heat, water is recirculated via a cooling tower; the failure of half of the ESWS pumps was one of the factors that endangered safety in the 1999 Blayais Nuclear Power Plant flood, while a total loss occurred during the Fukushima I and Fukushima II nuclear accidents in 2011. Emergency core cooling systems are designed to safely shut down a nuclear reactor during accident conditions; the ECCS allows the plant to respond to a variety of accident conditions and additionally introduce redundancy so that the plant can be shut down with one or more subsystem failures. In most plants, ECCS is composed of the following systems: The High Pressure Coolant Injection System consists of a pump or pumps that have sufficient pressure to inject coolant into the reactor vessel while it is pressurized.

It is designed to monitor the level of coolant in the reactor vessel and automatically inject coolant when the level drops below a threshold. This system is the first line of defense for a reactor since it can be used while the reactor vessel is still pressurized; the Automatic Depressurization System consists of a series of valves which open to vent steam several feet under the surface of a large pool of liquid water in pressure suppression type containments, or directly into the primary containment structure in other types of containments, such as large-dry or ice-condenser containments. The actuation of these valves depressurizes the reactor vessel and allows lower pressure coolant injection systems to function, which have large capacities in comparison to the high pressure systems; some depressurization systems are automatic in function, while others may require operators to manually activate them. In pressurized water reactors with large dry or ice condenser containments, the valves of the system are called Pilot operated release valves.

LPCI consists of a pump or pumps that inject coolant into the reactor vessel once it has been depressurized. In some nuclear power plants, LPCI is a mode of operation of a residual heat removal system. LPCI is not a stand-alone system; this system uses spargers within the reactor pressure vessel to spray water directly onto the fuel rods, suppressing the generation of steam. Reactor designs can include core spray in low-pressure modes; this system consists of a series of pumps and spargers that spray coolant into the upper portion of the primary containment structure. It is designed to condense the steam into liquid within the primary containment structure in order to prevent overpressure and overtemperature, which could lead to leakage, followed by involuntary depressurization; this system is driven by a steam turbine to provide enough water to safely cool the reactor if the reactor building is isolated from the control and turbine buildings.

Fraser MacPherson

John Fraser MacPherson CM was a Canadian jazz musician from Saint Boniface, Manitoba. MacPherson moved to British Columbia, as a child, he learned piano and alto and tenor saxophones. After moving to Vancouver to continue a commerce degree, he played in bands led by Ray Norris, Dave Robbins, Paul Ruhland, Doug Parke, he led his own groups and took over the leadership of the Cave supper club band. He took a year's leave in 1958 adding flute to his list of instruments, he played on the CBC and won a Juno Award for Best Jazz Album in 1983. He was awarded the Order of Canada in 1987. Throughout the 1960s and 1970s MacPherson was a first-call studio player in Vancouver, as well as leading the house band at the Cave supper club, he taught in the Jazz and Commercial Music department at Vancouver Community College, where his students included future Powder Blues Band baritone saxophonist Gordie Bertram and New Orleans based saxophonist and jazz educator John Doheny. Live at the Planetarium, MacPherson's first album as leader of a small jazz group, was recorded for broadcast on the French-language CBC radio network.

He released them on his own independent label, West End Records. The album was re-released by Concord Records, MacPherson went on to record several other releases for them, he recorded for Sackville Records in Toronto and Justin Time Records in Montreal. In the summer of 1993, Pacific Music Industry Association created the Fraser MacPherson Scholarship Fund which annually awards grants of $2000 to four to eight aspiring music students; that year MacPherson died in Vancouver at the age of 65.

Margaret Martyr

Margaret Martyr or Margaret Thornton was a British singer and actress. Martyr's parents were living in London when she was born in 1762, she came to notice in 1778. She was Hook's pupil and she sang there each summer until 1780, she moved to singing Ballad opera and appeared in Love in a Village at the Covent Garden Theatre in 1779. She married Captain Martyr and they had a daughter, her husband spent too much and died in 1783 - in Calais where he was escaping his debts. Martyr consoled herself with the prompter, James Wild, before establishing a lifelong partnership with the oboist William Thomas Parke, they had two sons but they never married. Martyr's style is said to have come from her "notorious" mentor Ann Catley. Thomas Bellamy wrote of Martyr in 1795 "Catley's pupil - Catley's boast, playful and free, Lovely MARTYR, hail to thee!"Before her sons were born she was earning ten pounds a week at the Covent Garden theatre where she appeared in "second woman" roles and in Breeches roles. In 1794 when she was playing Euphrosyne in Comus by George Colman the Elder.

Until 1804 she would spend each winter at Covent Garden and in the summer she would tour outside London and appear at Vauxhall Garedens. Martyr died on 7 June 1807 whilst still being paid by the Covent Garden theatre, she was buried in St Martin in the Fields. Martyr's will recognised her partner Parke as her executor and the farm she owned at Yalding was divided between her two sons after her daughter was given half of it. There are a number of portraits of Martyr including a 1794 painting by Gainsborough Dupont

Alms for Jihad

Alms for Jihad: Charity and Terrorism in the Islamic World is a 2006 book co-written by American authors J. Millard Burr, a former USAID relief coordinator in Sudan, historian Robert O. Collins which discusses the role of Islamic charities in financing terrorism. Introduction. In August 2007, the publisher, Cambridge University Press, attempted to have the work removed from circulation and pulped under pressure from a libel action lawsuit filed against them in the British legal system by wealthy Saudi businessman Khalid Salim A. Bin Mahfouz because the book accused him of funding al-Qaeda. Mahfouz had also forced the censorship of four other books: June 2006: "The Forbidden Truth" / "La Vérité Interdite" by Jean-Charles Brisard and Guillaume Dasquié April 2006: Funding Evil. CUP wrote to libraries asking them to remove copies from circulation. CUP subsequently sent out copies of an "errata" sheet; the American Library Association issued a recommendation to libraries still holding Alms for Jihad: "Given the intense interest in the book, the desire of readers to learn about the controversy first hand, we recommend that U.

S. libraries keep the book available for their users."The authors of the book opposed the course of action which CUP chose. CUP was criticized by some who claimed that its action was incompatible with freedom of speech and with freedom of the press, that it indicated that English libel laws were excessively strict. In The New York Times Book Review, United States Congressman Frank R. Wolf described Cambridge's settlement as "basically a book burning." This episode of "Libel Tourism" was fought in the United States and led to the passing of the Libel Terrorism Protection Act by New York State on April 29, 2008. CUP pointed out that, at that time, it had sold most of its copies of the book. Kevin Taylor, intellectual property director at Cambridge University Press, stated that the book cited sources "whose falsity had been established to the satisfaction of the English courts" in previous cases. Nathan Vardi published an article in Forbes magazine titled "Sins of the Father?" on March 18, 2002, with the heading: "Khalid bin Mahfouz, a Saudi billionaire, spent the 1990s engaged in financial folly and funding what the U.

S. government calls a front for Al-Qaeda. Now a new generation tries to escape the shadow."On December 1, 2015, in his article, "Banned by Lawfare Jihad, A Book You MUST Read: Alms for Jihad", Christopher W. Holton asserted, "Alms for Jihad contains the most detailed, exhaustive investigation into the role that Islamic charities and NGOs have played in financing and supporting violent Jihad and terrorist organizations, including Al Qaeda."
