Buildings And Structures In Schleswig-Holstein
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former Nuclear Power Stations In Germany
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ...

Nuclear Power In Germany
Nuclear power in Germany accounted for 13.3% of German electricity supply in 2021, generated by six power plants, of which three were switched off at the end of 2021, the other three due to cease operation at the end of 2022 according to the complete nuclear phase-out plan of 2011. However, in early 2022 this plan was called into question once more in light of the 2022 Russian invasion of Ukraine which threatens Germany's supply of natural gas. There have been calls to either delay the shutdown of the remaining three reactors or to restart operation in those reactors that were shut down in late 2021. German nuclear power began with research reactors in the 1950s and 1960s with the first commercial plant coming online in 1969. Nuclear power has been a topical political issue in recent decades, with continuing debates about when the technology should be phased out. The anti-nuclear movement in Germany has a long history dating back to the early 1970s, when large demonstrations pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transformer
A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signal-processing circuits. Since the invention of the first constant-potential transfo ...

Leukemia
Leukemia ( also spelled leukaemia and pronounced ) is a group of blood cancers that usually begin in the bone marrow and result in high numbers of abnormal blood cells. These blood cells are not fully developed and are called ''blasts'' or ''leukemia cells''. Symptoms may include bleeding and bruising, bone pain, fatigue, fever, and an increased risk of infections. These symptoms occur due to a lack of normal blood cells. Diagnosis is typically made by blood tests or bone marrow biopsy. The exact cause of leukemia is unknown. A combination of genetic factors and environmental (non-inherited) factors are believed to play a role. Risk factors include smoking, ionizing radiation, petrochemicals (such as benzene), prior chemotherapy, and Down syndrome. People with a family history of leukemia are also at higher risk. There are four main types of leukemia— acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL) and chronic ...

Zwentendorf Nuclear Power Plant
The Zwentendorf Nuclear Power Plant was the first commercial nuclear plant for electric power generation built in Austria, of 3 nuclear plants originally envisioned. Construction of the plant at Zwentendorf, Austria was finished but the plant never entered service. The start-up of the Zwentendorf plant, as well as the construction of the other 2 plants, was prevented by a referendum on 5 November 1978, in which a narrow majority of 50.47% voted against the start-up.Austria's no to nuclear power Peter WeishAustria‘s Anti-Nuclear Crusade Euro Nuclear Construction of the plant began in April 1972, a ...

Isar Nuclear Power Plant
Isar I and Isar II are two base load nuclear power plants which have been built in Germany next to the Isar river. They are fourteen kilometres away from Landshut, between Essenbach and Niederaichbach. Safety Passive safety features The safety feature begins with the passive safety feature which includes the radioactive materials in the reactor core (also by accidents) to protect them from the outside environment. Fuel pellets, fuel rod casings, reactor pressure vessel, biological shield, steel containment structure and the outer ferro concrete mantle are six of the most important passive safety features. Active safety features The passive safety installations are supplemented by a lot of automatically working active safety systems whose reliableness is based on their plural existence and their autonomously working in separate rooms. This is as necessary for the internal electric power supply as for the reactor cooling system, which guarantees the reliable thermal dissipati ...

Boiling Water Reactor
A boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. It is a design different from a Soviet graphite-moderated RBMK. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), which is also a type of light water nuclear reactor. The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to steam and then drives a steam turbine. In a PWR, the reactor core heats water, which does not boil. This hot water then exchanges heat with a lower pressure system, which turns water into steam that drives the turbine. The BWR was developed by the Argonne National Laboratory and General Electric (GE) in the mid-1950s. The main present manufacturer is GE Hitachi Nuclear Energy, which specializes in the design and construction of this type of reactor. Overview A boiling water reactor uses demineralized water as a coolant and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vattenfall
Vattenfall is a Swedish multinational power company owned by the Swedish State. Beyond Sweden, the company generates power in Denmark, Finland, Germany, the Netherlands, and the United Kingdom. The company's name is Swedish for "waterfall", and is an abbreviation of its original name, Royal Waterfall Board (''Kungliga Vattenfallstyrelsen''). History Vattenfall (then called ''Kungliga Vattenfallsstyrelsen'' or Royal Waterfall Board) was founded in 1909 as a state-owned enterprise in Sweden. From its founding until the mid-1970s, Vattenfall's business was largely restricted to Sweden, with a focus on hydroelectric power generation. Only in 1974 did the company begin to build nuclear reactors in Sweden (the Ringhals 1 and 2 reactors), eventually owning seven of Sweden's 12 reactors. In 1992, Vattenfall was reformed as the limited liability company Vattenfall AB. At the same time, the transmission grid (220 kV and 400 kV lines) was transferred to the newly formed state agency Sve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
