Military Physics Institute
Military Physics Institute (, MFI) was a Swedish research institution established in 1941 to 1945. It was amalgamated into the Swedish National Defence Research Institute in 1945. History The initiative for the establishment of the Military Physics Institute was taken in 1939 when the leaders of the country's physical institutions joined forces to make more effective use of the physical research results for military purposes. The Military Physics Institute was established in 1940 by the Swedish National Committee for Physics (''Svenska nationalkommitten för fysik'') and the year after state funding for the operation was applied. Research within the Military Physics Institute focused on the development of new weapons of defense. These include surveys of the military use of infrared radiation as well as the problems of shaped charge. An area in Södertörn near Grindsjön was donated by Olof Arrhenius, at which the institute built a test station for the operations. The Military Phys ...

Swedish National Defence Research Institute
Swedish National Defence Research Institute (, FOA) was a Swedish government agency in defense research existing from 1945 to 31 December 2000. It was amalgamated with the National Aeronautical Research Institute (FFA) into the Swedish Defence Research Agency (FOI) which was established on 1 January 2001. History The National Defence Research Institute (FOA) was established in 1945 (Instruction TS C:II No. 24), and took over operations at the Swedish Armed Forces Chemical Institute (''Försvarsväsendets kemiska anstalt'', FKA), the Military Physics Institute and the Telecommunications Technical Working Group of the Swedish Board of Inventions (''Statens uppfinnarnämnds teletekniska arbetsgrupp'', SUN), that is, essentially all technical and scientific research outside the industry. FOA was organized in three research departments, FOA 1 chemistry/medicine, FOA 2 general physics and FOA 3 telecommunications and an office. In 1959 FOA 4 (nuclear physics and nuclear chemistry) ...

National Archives Of Sweden
The National Archives of Sweden (, RA) is the official archive of the Swedish government and is responsible for the management of records from Sweden's public authorities. Although the archives functions primarily as the government archive, it also preserves some documents from private individuals and non-public organizations. The mission of the archives is to collect and preserve records for future generations. Organization The National Archives of Sweden is a state administrative authority, organized under the Ministry of Culture. The head of The National Archives, known as the Riksarkivarie in Swedish, works alongside of staff responsible for strategic issues, and overall coordination and development. The position is currently held by Karin Åström Iko. History The National Archives of Sweden is one of the oldest public authorities in Sweden, with roots that can be traced back to the Middle Ages. Beginning under King Gustav Vasa, an archive was created from previously ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrared
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally (according to ISO, CIE) understood to include wavelengths from around to . IR is commonly divided between longer-wavelength thermal IR, emitted from terrestrial sources, and shorter-wavelength IR or near-IR, part of the solar spectrum. Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires e ...

Shaped Charge
A shaped charge, commonly also hollow charge if shaped with a cavity, is an explosive charge shaped to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry. A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though depths of 10 CD and above have been achieved. Contrary to a misconception, possibly resulting from the acronym ''HEAT'' (high-explosive anti-tank), the shaped charge does not depend in any way on heating or melting for its effectiveness; that is, the jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature—however the process creates significant heat and often has a significant secondary incendiary ef ...

Södertörn
Södertörn is a roughly triangular peninsula and artificial island in eastern Södermanland, Sweden, with an area of 1,207 km² and is bordered by: *Lake Mälaren, the Hammarby Canal and the inlet of Saltsjön (a part of the Baltic Sea) to the north, *The Baltic Sea (the Stockholm Archipelago) to the east and the south, * Himmerfjärden and Hallsfjärden (parts of the Baltic Sea) to the west as well as *The Södertälje Canal to the northwest. The Södertälje Canal and Hammarby Canal are man-made waterways, so the peninsula of Södertörn is not fully separated from (the rest of) the Swedish mainland or the island of Södermalm by nature, although Södertörn is classified as an island by Statistics Sweden, and the third largest island in Sweden. Since 2005, the whole of Södertörn has been included in Metropolitan Stockholm. Before that, the southern parts of the island, which lie within Nynäshamn Municipality, and the western parts, which are in Södertälje Muni ...

Physics Research Institutes
Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." It is one of the most fundamental scientific disciplines. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (...) You will come to see physics as a towering achievement of the human intellect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Research Of Sweden
A military, also known collectively as armed forces, is a heavily Weapon, armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstructi ...

Research Institutes In Sweden
Research is creative and systematic work undertaken to increase the stock of knowledge. It involves the collection, organization, and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion of past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Government Agencies Established In 1941
A government is the system or group of people governing an organized community, generally a state. In the case of its broad associative definition, government normally consists of legislature, executive, and judiciary. Government is a means by which organizational policies are enforced, as well as a mechanism for determining policy. In many countries, the government has a kind of constitution, a statement of its governing principles and philosophy. While all types of organizations have governance, the term ''government'' is often used more specifically to refer to the approximately 200 independent national governments and subsidiary organizations. The main types of modern political systems recognized are democracies, totalitarian regimes, and, sitting between these two, authoritarian regimes with a variety of hybrid regimes. Modern classification systems also include monarchies as a standalone entity or as a hybrid system of the main three. Historically prevalent forms ...
