Commanders Crosses Of The Order Of Merit Of The Federal Republic Of Germany
Commander (commonly abbreviated as Cmdr.) is a common naval officer rank. Commander is also used as a rank or title in other formal organizations, including several police forces. In several countries this naval rank is termed frigate captain. Commander is also a generic term for an officer commanding any armed forces unit, for example "platoon commander", "brigade commander" and "squadron commander". In the police, terms such as "borough commander" and "incident commander" are used. Commander as a naval and air force rank Commander is a rank used in navies but is very rarely used as a rank in armies. The title, originally "master and commander", originated in the 18th century to describe naval officers who commanded ships of war too large to be commanded by a lieutenant but too small to warrant the assignment of a post-captain and (before about 1770) a sailing master; the commanding officer served as his own master. In practice, these were usually unrated sloops-of-war ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymer Scientists And Engineers
A polymer (; Greek ''poly-'', "many" + '' -mer'', "part") is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compounds, produces unique physical properties including toughness, high elasticity, viscoelasticity, and a tendency to form amorphous and semicrystalline structures rather than crystals. The term "polymer" derives from the Greek word πολύς (''polus'', meaning "many, much") and μέρος (''meros'', meani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Rostock Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens ...

Kölleda
Kölleda (until 1927 Cölleda) is a small rural town in Thuringia. The municipality belongs to the district of Sömmerda and is located about ten kilometres east of the district town of Sömmerda on the edge of the Thuringian Basin. It is the third largest municipality in the district with about 6300 inhabitants. Kölleda is the seat of the Kölleda administrative community, although it does not belong to it. The inhabitants are called "Kölledaer". Kölleda is a sub-centre for the region. The town is characterised by a former traditionally large cultivation of medicinal and aromatic herbs, especially peppermint. This led to the nickname "peppermint town" and "peppermint railway" for the Straußfurt- Großheringen railway line that runs past. Kölleda has an eventful 1200-year old history. Significant for the town's development during the National Socialist era were the construction of an air base and an aircraft office for the Luftwaffe and later, during the GDR era, the VEB F ...

Sergei Vasiljevich Lebedev
Sergei Vasilievich Lebedev (russian: Сергей Васильевич Лебедев; 13 July 1874 – 2 May 1934) was a Russian/Soviet chemist and the inventor of polybutadiene synthetic rubber, the first commercially viable and mass-produced type of synthetic rubber. Biography Lebedev was born in 1874 in Lublin and went to school in Warsaw. In 1900, he graduated from St. Petersburg University and found work at the Petersburg Margarine Factory. Starting in 1902, Lebedev moved from university to university in Russia, starting at the Saint-Petersburg Institute for Railroad Engineering. In 1904, he returned to St. Petersburg University to work under Alexey Favorsky ( Stalin Prize, 1941, for contributions to the manufacture of synthetic rubber). In 1905, he married his second wife, the artist Anna Ostroumova-Lebedeva. In 1915, Lebedev was appointed Professor at the Women's Pedagogical Institute in St. Petersburg.

Hermann Emil Fischer
Hermann Emil Louis Fischer (; 9 October 1852 – 15 July 1919) was a German chemist and 1902 recipient of the Nobel Prize in Chemistry. He discovered the Fischer esterification. He also developed the Fischer projection, a symbolic way of drawing asymmetric carbon atoms. He also hypothesized lock and key mechanism of enzyme action. He never used his first given name, and was known throughout his life simply as Emil Fischer. Early years and career Fischer was born in Euskirchen, near Cologne, the son of Laurenz Fischer, a businessman, and his wife Julie Poensgen. After graduating he wished to study natural sciences, but his father compelled him to work in the family business until determining that his son was unsuitable. Fischer then attended the University of Bonn in 1871, but switched to the University of Strasbourg in 1872. He earned his doctorate in 1874 under Adolf von Baeyer with his study of phthaleins, and was appointed to a position at the university. After eight yea ...
