Zakłady Mechaniczne Tarnów
Zakłady Mechaniczne Tarnów (; ) is a Polish defense manufacturing company. Based in the city of Tarnów, the company produces handguns, assault rifles, sniper rifles and anti-air guns. It is part of the Bumar-Labedy corporation, itself a division of the state-controlled Polish Armaments Group. History Initially founded during World War I in 1917 as a local train repair workshop, in the interwar period the company was part of the Polish State Railways. After the company's equipment was confiscated, dismantled and sent to Germany during World War II, the factory was rebuilt as a train repair workshop, but in 1951 it was turned into a defence contractor producing guns, firearms and machine tools. Warsaw Pact years From 1951 the company license-built M1939 37 mm automatic air defense guns and Nudelman N-37 aircraft cannons used in LiM-2 and MiG-17 fighters. While Poland was still in the Warsaw Pact, other types of Soviet-designed military equipment were also introduced: 57 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ZSU-23-4 Shilka
The ZSU-23-4 "Shilka" is a lightly armored Soviet self-propelled, radar-guided Anti-aircraft warfare, anti-aircraft weapon system (Self-propelled anti-aircraft weapon, SPAAG). It was superseded by the 2K22 Tunguska (SA-19 Grison). Etymology The acronym "ZSU" stands for ''Zenitnaya Samokhodnaya Ustanovka'' (), meaning "anti-aircraft self-propelled system"; the "23" signifies the bore diameter in millimetres; the "4" signifies the number of gun barrels. It is named after the Shilka River in Russia. Afghan soldiers nicknamed it the "sewing machine" due to the sound of its cannons firing. It is also referred to by its nickname of "Zeus", derived from the Russian acronym. History The previous Soviet self-propelled anti-aircraft gun (SPAAG), the ZSU-57-2, was armed with two 57 mm autocannons; it was aimed optically using a basic tracking and lead calculating system. The ZSU-57-2 was not particularly successful despite its very powerful autocannons; given their large caliber, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science And Technology In Poland
Education has been of prime interest to Poland's rulers since the early 12th century. The catalog of the library of the Cathedral Chapter in Kraków dating from 1110 shows that Polish scholars already then had access to western European literature. In 1364, King Casimir III the Great founded the Cracow Academy, which would become one of the great universities of Europe. The Polish people have made considerable contributions in the fields of science, technology and mathematics. The list of famous scientists in Poland begins in earnest with the polymath, astronomer and mathematician Nicolaus Copernicus, who formulated the heliocentric theory and sparked the European Scientific Revolution. In 1773, King Stanisław August Poniatowski established the Komisja Edukacji Narodowej, Commission of National Education (, KEN), the world's first ministry of education. After the Partitions of Poland, third partition of Poland, in 1795, no Polish state existed. The 19th and 20th centuries saw man ...

Armoured Fighting Vehicles Of Poland
Armour (Commonwealth English) or armor (American English; see spelling differences) is a covering used to protect an object, individual, or vehicle from physical injury or damage, especially direct contact weapons or projectiles during combat, or from a potentially dangerous environment or activity (e.g. cycling, construction sites, etc.). Personal armour is used to protect soldiers and war animals. Vehicle armour is used on warships, armoured fighting vehicles, and some combat aircraft, mostly ground attack aircraft. A second use of the term ''armour'' describes armoured forces, armoured weapons, and their role in combat. After the development of armoured warfare, tanks and mechanised infantry and their combat formations came to be referred to collectively as "armour". Etymology The word "armour" began to appear in the Middle Ages as a derivative of Old French. It is dated from 1297 as a "mail, defensive covering worn in combat". The word originates from the Old French ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ResearchGate
ResearchGate is a European commercial social networking site for scientists and researchers to share papers, ask and answer questions, and find collaborators. According to a 2014 study by ''Nature'' and a 2016 article in ''Times Higher Education'', it is the largest academic social network in terms of active users, although other services have more registered users, and a 2015–2016 survey suggests that almost as many academics have Google Scholar profiles. While reading articles does not require registration, people who wish to become site members need to have an email address at a recognized institution or to be manually confirmed as a published researcher in order to sign up for an account. Articles are free to read by visitors, however additional features (such as job postings or advertisements) are accessible only as a paid subscription. Members of the site each have a user profile and can upload research output including papers, data, chapters, negative results, patents, r ...

Self-propelled Anti-aircraft Gun
An anti-aircraft vehicle, also known as a self-propelled anti-aircraft gun (SPAAG) or self-propelled air defense system (SPAD), is a mobile vehicle with a dedicated anti-aircraft capability. Specific weapon systems used include machine guns, autocannons, larger guns, or surface-to-air missiles, and some mount both guns and longer-ranged missiles (e.g. the Pantsir missile system). Platforms used include both trucks and heavier combat vehicles such as armoured personnel carriers and tanks, which add protection from aircraft, artillery, and small arms fire for front line deployment. Anti-aircraft guns are usually mounted in a quickly-traversing turret with a high rate of elevation, for tracking fast-moving aircraft. They are often in dual or quadruple mounts, allowing a high rate of fire. In addition, most anti-aircraft guns can be used in a direct-fire role against surface targets to great effect. Today, surface-to-air missiles (generally mounted on similar turrets) have largel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White
White is the lightest color and is achromatic (having no chroma). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully (or almost fully) reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France as well as the flag of monarchist France from 1815 to 1830, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek temples and Roman temples were faced with white marble, and beginning in the 18t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
