Glasmine 43
The Glasmine 43 was an anti-personnel mine with a glass body used by the Nazi Germany during World War II. This mine was an early form of minimum metal mine, designed with the minimum amount of metal to reduce the likelihood of detection by the Polish mine detector then in use by Allied forces. The reduced use of metal was also beneficial because it saved this valuable war resource for other uses. Description The mine consists of a glass bowl, in diameter containing an explosive charge and a detonator. The top of the mine was covered by a sheet-glass disk thick, under a thick, moulded glass pressure plate. Each mine was supplied with a small quantity of cement putty to seal gaps between the main body and the glass disk cover and make the mine waterproof. When stepped on, the pressure plate shattered the glass disk and activated the detonator, detonating the mine's main explosive charge. This was a ''Sprengkörper'' 28 – a standard demolition charge with of explosive. Two typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-personnel Mine
Anti-personnel mines are a form of mine designed for use against humans, as opposed to anti-tank mines, which are designed for use against vehicles. Anti-personnel mines may be classified into blast mines or fragmentation mines; the latter may or may not be a bounding mine. The mines are often designed to injure, not kill, their victims to increase the logistical (mostly medical) support required by enemy forces that encounter them. Some types of anti-personnel mines can also damage the tracks on armoured vehicles or the tires of wheeled vehicles. The International Campaign to Ban Landmines has sought to ban mines culminating in the 1997 Ottawa Treaty, although this treaty has not yet been accepted by over 30 countries. Use Anti-personnel mines are used in a similar manner to anti-tank mines, in static "mine fields" along national borders or in defense of strategic positions as described in greater detail in the land mine article.

Fragmentation (weaponry)
Fragmentation is the process by which the casing, shot, or other components of an anti-personnel weapon, bomb, barrel bomb, land mine, IED, artillery, mortar, tank gun, or autocannon shell, rocket, missile, grenade, etc. are dispersed and/or shattered by the detonation of the explosive filler. The correct term for these pieces is "fragmentation"; "shards" or "splinters" can be used for non-preformed fragments. Preformed fragments can be of various shapes (spheres, cubes, rods, etc.) and sizes, and are normally held rigidly within some form of matrix or body until the high explosive (HE) filling is detonated. The resulting high-velocity fragments produced by either method are the main lethal mechanisms of these weapons, rather than the heat or overpressure caused by detonation, although offensive grenades are often constructed without a frag matrix. These casing pieces are often incorrectly referred to as "shrapnel", particularly by non-military media sources. History The ...

World War II Infantry Weapons Of Germany
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keiler (mine Flail)
Keiler mine flail (german: Minenräumpanzer Keiler, 'tusker') is a mine-clearing vehicle developed by Rheinmetall in Germany to meet German Army requirements. It is a conversion of the M48 Patton medium tank chassis in combination with a German MTU MB 871 Ka 501 liquid-cooled turbocharged Diesel engine. The main role of the Keiler vehicle is to clear a lane through minefields to let soldiers and vehicles pass safely. A deployable mine flail system has been fixed to the front of the vehicle, being used to clear both anti-tank and anti-personnel mines. Between 1997 and 1998, 24 vehicles of this kind were produced for the German Army. Design Keiler is built on the M48 Patton medium tank hull. Developers removed the turret of the Patton and fitted the vehicle with a heavy-duty rotor-powered mine flail, a rapidly rotating cylinder mounted between two arms in front of the vehicle consisting of two shafts with 24 chains terminating in large metal "feet". In traveling mode, the mine flail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mine Flail
A mine flail is a vehicle-mounted device that makes a safe path through a minefield by deliberately detonating land mines in front of the vehicle that carries it. They were first used by the British during World War II. The mine flail consists of a number of heavy chains ending in fist-sized steel balls (flails) that are attached to a horizontal, rapidly rotating rotor mounted on two arms in front of the vehicle. The rotor's rotation makes the flails spin wildly and violently pound the ground. The force of a flail strike above a buried mine mimics the weight of a person or vehicle and causes the mine to detonate, but in a safe manner that does little damage to the flails or the vehicle. World War II The idea is commonly attributed to a South African soldier, Captain Abraham du Toit. A test rig was constructed in South Africa and results were so encouraging that du Toit was promoted and sent to England to develop the idea. Before du Toit left for England, he described his idea to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutschlandfunk
Deutschlandfunk (DLF, ''Broadcast Germany'') is a public-broadcasting radio station in Germany, concentrating on news and current affairs. It is one of the four national radio channels produced by Deutschlandradio. History Broadcasting in the Federal Republic of Germany is reserved under the Basic Law (constitution) to the states. This means that all public broadcasting is regionalised. National broadcasts must be aired through the national consortium of regional public broadcasters ( ARD) or authorized by a treaty negotiated between the states. In the 1950s, the German Democratic Republic (GDR) began broadcasting its Deutschlandsender station on longwave. In response to this, the then-Nordwestdeutscher Rundfunk applied for a licence to operate a similar longwave service on behalf of the ARD. This was granted in 1956 and operated as Deutscher Langwellensender ("German Longwave Station"). On 29 November 1960, the federal government under Konrad Adenauer created ''Deutschlan ...

Vogelsang Military Training Area
Vogelsang Training Area (german: Truppenübungsplatz Vogelsang) lay in the German North Eifel hills between the villages of Simmerath, Heimbach and Schleiden in the state of North Rhine-Westphalia. It was established in 1946 and handed back at the end of 2005, and consisted of the grounds of the former Nazi leadership training centre in the fort of Vogelsang (''Ordensburg Vogelsang'') on the Erpenscheid hill plus additional terrain including the so-called Dreiborn Plateau. In the north and east it was bounded by the Urft Reservoir. The training area had an area of around 45 km2 and since 1 January 2006 has been fully incorporated into the Eifel National Park. at www2.kamp-vogelsang.be. Retrieved 26 Dec 2013.

Eifel National Park
The Eifel National Park (german: Nationalpark Eifel) is the 14th national park in Germany and the first in North Rhine-Westphalia. The park was founded in 2004, and is classified as a "national park in development". Eifel National Park is part of the much larger High Fens – Eifel Nature Park, a cross-border protection between Germany and Belgium established in 1960. General The aims of the Eifel National Park accord with those set out by the International Union for Conservation of Nature and Natural Resources, IUCN. These require that at least 75 percent of the national park's area must be left to develop naturally – i.e. must not be given over to human use – within 30 years of the foundation of the park. Aims, mechanisms and executive bodies are laid down in the National Park Regulation (''Nationalpark-Verordnung'' or ''NP-VO''). The relatively young national park lies in the north of the Eifel region between Nideggen in the north, Gemünd in the south and the Belgi ...

Infection
An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently bacteria and viruses. Hosts can fight infections using their immune system. Mammalian hosts react to infections with an innate response, often involving inflammation, followed by an adaptive response. Specific medications used to treat infections include antibiotics, antivirals, antifungals, antiprotozoals, and antihelminthics. Infectious diseases resulted in 9.2 million deaths in 2013 (about 17% of all deaths). The branch of medicine that focuses on infections is referred to as infectious disease. Types Infections are caused by infectious agents (pathogens) including: * Bacteria (e.g. ''Mycobacterium tuberculosis'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X-ray
An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz ( to ) and energies in the range 145 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . Spellings of ''X-ray(s)'' in English include the variants ''x-ray(s)'', ''xray(s)'', and ''X ray(s)''. The most familiar use of X-rays is checking for fractures (broken bones), but X-rays are also used in other ways. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Detonator
A detonator, frequently a blasting cap, is a device used to trigger an explosive device. Detonators can be chemically, mechanically, or electrically initiated, the last two being the most common. The commercial use of explosives uses electrical detonators or the capped fuse which is a length of safety fuse to which an ordinary detonator has been joined. Many detonators' primary explosive is a material called ASA compound. This compound is formed from lead azide, lead styphnate and aluminium and is pressed into place above the base charge, usually TNT or tetryl in military detonators and PETN in commercial detonators. Other materials such as DDNP (diazo dinitro phenol) are also used as the primary charge to reduce the amount of lead emitted into the atmosphere by mining and quarrying operations. Old detonators used mercury fulminate as the primary, often mixed with potassium chlorate to yield better performance. A blasting cap is a small sensitive primary explosive device ge ...
