Adrianov Compass
The Adrianov compass (russian: Компас Адрианова) is a military compass designed by Russian Imperial Army topographist in 1907. Wrist-worn versions of the compass were then adopted and widely used by the Red and Soviet Army. Some of the older production examples (differentiated by the brownish color of their glow-in-the-dark markings, like the one in the photo) are slightly radioactive because of Radium-226 used in their dials. Newer ones, with teal or white paint color, use the non-radioactive phosphorescent paint. References Travel gear Navigational equipment Military equipment of Russia {{Russia-mil-stub ...

Compass
A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north. Other methods may be used, including gyroscopes, magnetometers, and GPS receivers. Compasses often show angles in degrees: north corresponds to 0°, and the angles increase clockwise, so east is 90°, south is 180°, and west is 270°. These numbers allow the compass to show azimuths or bearings which are commonly stated in degrees. If local variation between magnetic north and true north is known, then direction of magnetic north also gives direction of true north. Among the Four Great Inventions, the magnetic compass was first invented as a device for divination as early as the Chinese Han Dynasty (since c. 206 BC),Li Shu-hua, p. 176 and later adopted for navigation by the Song Dynasty Chinese during the 11th centur ...

Imperial Russian Army
The Imperial Russian Army (russian: Ру́сская импера́торская а́рмия, tr. ) was the armed land force of the Russian Empire, active from around 1721 to the Russian Revolution of 1917. In the early 1850s, the Russian Army consisted of more than 900,000 regular soldiers and nearly 250,000 irregulars (mostly Cossacks). Precursors: Regiments of the New Order Russian tsars before Peter the Great maintained professional hereditary musketeer corps known as '' streltsy''. These were originally raised by Ivan the Terrible; originally an effective force, they had become highly unreliable and undisciplined. In times of war the armed forces were augmented by peasants. The regiments of the new order, or regiments of the foreign order (''Полки нового строя'' or ''Полки иноземного строя'', ''Polki novovo (inozemnovo) stroya''), was the Russian term that was used to describe military units that were formed in the Tsardom of Russi ...

Topography
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically ''relief'', even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form (DEM). It is often considered to include the graphic representation of t ...

Red Army
The Workers' and Peasants' Red Army (Russian: Рабо́че-крестья́нская Кра́сная армия),) often shortened to the Red Army, was the army and air force of the Russian Soviet Federative Socialist Republic and, after 1922, the Union of Soviet Socialist Republics. The army was established in January 1918. The Bolsheviks raised an army to oppose the military confederations (especially the various groups collectively known as the White Army) of their adversaries during the Russian Civil War. Starting in February 1946, the Red Army, along with the Soviet Navy, embodied the main component of the Soviet Armed Forces; taking the official name of "Soviet Army", until its dissolution in 1991. The Red Army provided the largest land force in the Allied victory in the European theatre of World War II, and its invasion of Manchuria assisted the unconditional surrender of Imperial Japan. During operations on the Eastern Front, it accounted for 75–80% of casual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DOSAAF
DOSAAF (russian: ДОСААФ), full name ''Volunteer Society for Cooperation with the Army, Aviation, and Navy'' (russian: Добровольное общество содействия армии, авиации и флоту), was a paramilitary sport organization in the Soviet Union, concerned mainly with weapons, automobiles and aviation. The society was established in 1927 as OSOAVIAKhIM and from 1951 to 1991 carried the name of DOSAAF. The society was preserved in some post-Soviet Republics, e.g. Russia and Belarus, although these may use a different name. In Ukraine, for example, the counterpart is "Society of Assistance to Defense of Ukraine". In Russia it was reformed in December 1991 as the Russian Defense Sports-Technical Organization (ROSTO; russian: Российская оборонная спортивно-техническая организация – РОСТО). In December 2009, ROSTO was renamed DOSAAF Russia. For Belarus, see DOSAAF (Belarus). The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania State University Libraries
The Penn State University Libraries consists of 36 libraries at 22 locations in the Commonwealth of Pennsylvania. The two main buildings on Penn State's University Park campus are the Pattee and Paterno libraries. History The library's first permanent location was in Old Main, with 1,500 books in agriculture and the sciences. In 1904, the library was moved to the Carnegie Building (then "Carnegie Library"), which provided a 50,000 book capacity. By 1940, the library's collection had grown to 150,000, overcrowding Carnegie by three times its capacity. The library was permanently moved to the Pattee Library building. By the 1960s, the collection had grown to 800,000 books. The Pattee Library was renovated in the late 1990s, and in 2000, it was rededicated along with the new Paterno Library, a portion of which comprises the former East Wing of Pattee. Today, there are 14 libraries at the University Park campus alone, and the Libraries boast a collection of more than 5.4 millio ...

Luminous Paint
Luminous paint or luminescent paint is paint that exhibits luminescence. In other words, it gives off Visible spectrum, visible light through fluorescence, phosphorescence, or radioluminescence. There are three types of luminous paints: fluorescent paint, phosphorescent paint and radioluminescent paint. Fluorescent paint Fluorescence, Fluorescent paints 'glow' when exposed to short-wave ultraviolet (UV) radiation. These UV wavelengths are found in sunlight and many artificial lights, but the paint requires a special black light to view so these glowing-paint applications are called 'black-light effects'. Fluorescent paint is available in a wide range of colors and is used in Theatrical Lighting, theatrical lighting and effects, posters, and as entertainment for children. The fluorescent chemicals in fluorescent paint absorb the invisible UV radiation, then emit the energy as longer wavelength visible light of a particular color. Human eyes perceive this light as the unusual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radioactive
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay ( ), beta decay ( ), and gamma decay ( ), all of which involve emitting one or more particles. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetism and nuclear force. A fourth type of common decay is electron capture, in which an unstable nucleus captures an inner electron from one of the electron shells. The loss of that electron from the shell results in a cascade of electrons dropping down to that lower shell resulting in emission of discrete X-rays from the transitions. A common example is iodine-125 commonly used in medical settings. Radioactive decay is a stochastic (i.e. random) process ...

Radium-226
Radium (88Ra) has no stable or nearly stable isotopes, and thus a standard atomic weight cannot be given. The longest lived, and most common, isotope of radium is 226Ra with a half-life of . 226Ra occurs in the decay chain of 238U (often referred to as the radium series). Radium has 33 known isotopes from 202Ra to 234Ra. In 2013 it was discovered that the nucleus of radium-224 is pear-shaped. This was the first discovery of an asymmetric nucleus.
