Scanian Anti-Aircraft Corps
Scanian Anti-Aircraft Corps ( sv, Skånska luftvärnskåren, Lv 4) was a Swedish Army anti-aircraft unit that operated between 1941 and 1997. The unit was first based in Malmö and later in Ystad. History Through the Defence Act of 1936, the air defense was given a more independent role in the Swedish artillery, which among other things resulted in a number of anti-aircraft divisions being organized, where, among other things, a division was relocated to Malmö. The division was raised as a preparedness division of Östgöta Anti-Aircraft Artillery Regiment (A 10) on 1 October 1941 under the name Malmö Anti-Aircraft Division (A 9 L). Through the Defence Act of 1942, it was decided to separate the air defense from the artillery, to form its own corps. The change resulted, among other things, in the Malmö Anti-Aircraft Division being separated from Östgöta Anti-Aircraft Artillery Regiment, and formed on 1 October 1942 the Scanian Anti-Aircraft Corps (Lv 4).

Swedish Armed Forces
The Swedish Armed Forces ( sv, Försvarsmakten, "the Defense Force") is the government agency that forms the armed forces of Sweden, tasked with the defense of the country as well as with promoting Sweden's wider interests, supporting international peacekeeping, and providing humanitarian aid. It consists of the Swedish Army, the Swedish Air Force and the Swedish Navy, as well as a military reserve force, the Home Guard. Since 1994, all Swedish military branches are organized within a single unified government agency, headed by the Supreme Commander, even though the individual services maintain their distinct identities. The Swedish Armed Forces is made up of 23,600 active personnel, 11,200 military reserves, 24,000 Home Guard and 5,200 conscripts (set to increase to 8,000 conscripts by 2024) as of 2022. Units of the Swedish Armed Forces are currently on deployment in several international operations either actively or as military observers, including Afghanistan as part ...

Defence District
A defence district ( sv, Försvarsområde, Fo) was a military subdivision of the Swedish Armed Forces created in 1914. It was a lower regional level subdivision, usually corresponding to a Swedish county. The commander of a defence district was the Defence District Commander, who usually commanded local defence units, including infantry, engineers, air defence and light artillery, as well as any Home Guard units in the district. The commander answered to the larger military district that the defence district was part of. History A defence district was the lowest regional unit in the Swedish Armed Forces. Such were found in particularly important coastal areas during World War I and from 1939 on at a time of mobilization. From 1943 they were included as part of the ordinary peace organization. The district was responsible for defence planning, home defence, supervision of fixed facilities, certain territorial units and the Home Guard equipment and equipment. In 1973-76, the defen ...

Betula Pendula
''Betula pendula'', commonly known as silver birch, warty birch, European white birch, or East Asian white birch, is a species of tree in the family Betulaceae, native to Europe and parts of Asia, though in southern Europe, it is only found at higher altitudes. Its range extends into Siberia, China, and southwest Asia in the mountains of northern Turkey, the Caucasus, and northern Iran. It has been introduced into North America, where it is known as the European white birch or weeping birch and is considered invasive in some states in the United States and parts of Canada. The tree can also be found in more temperate regions of Australia. The silver birch is a medium-sized deciduous tree that owes its common name to the white peeling bark on the trunk. The twigs are slender and often pendulous and the leaves are roughly triangular with doubly serrate margins and turn yellow and brown in autumn before they fall. The flowers are catkins and the light, winged seeds get widely s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birch
A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech- oak family Fagaceae. The genus ''Betula'' contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are a typically rather short-lived pioneer species widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Description Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. The fruit is a small samara, although the wings may be obscure in some species. They differ from the alders (''Alnus'', another genus in the family) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moiré Pattern
In mathematics, physics, and art, moiré patterns ( , , ) or moiré fringes are large-scale interference patterns that can be produced when an opaque ruled pattern with transparent gaps is overlaid on another similar pattern. For the moiré interference pattern to appear, the two patterns must not be completely identical, but rather displaced, rotated, or have slightly different pitch. Moiré patterns appear in many situations. In printing, the printed pattern of dots can interfere with the image. In television and digital photography, a pattern on an object being photographed can interfere with the shape of the light sensors to generate unwanted artifacts. They are also sometimes created deliberately – in micrometers they are used to amplify the effects of very small movements. In physics, its manifestation is wave interference such as that seen in the double-slit experiment and the beat phenomenon in acoustics. Etymology The term originates from '' moire'' (''moiré ...
