Karl Brandt (zoologist)
Andreas Heinrich Karl Brandt (23 May 1854, Schönebeck near Magdeburg – 7 January 1931, Kiel) was a German zoologist and marine biologist. He studied natural sciences in Berlin, receiving his doctorate in 1877 at the University of Halle. Following graduation he served as an assistant to Emil Du Bois-Reymond (1818–1896) at the physiological institute of the University of Berlin. From 1882 to 1885 he worked at the zoological station in Naples, and in 1885 obtained his habilitation from the University of Königsberg under the direction of Carl Chun (1852–1914). From 1888 he was a professor of zoology at the University of Kiel, where he also served as director of the zoological institute and museum. Additionally, from 1887 to 1913 he taught classes at the German Imperial Naval Academy. In 1922 Brandt became professor emeritus, and in 1924 was appointed chairman of the ''Preußischen wissenschaftlichen Kommission zur Untersuchung der deutschen Meere'' (Prussian Scientific Commiss ...

Schönebeck
Schönebeck (), officially Schönebeck (Elbe), is a town in the district of Salzlandkreis, in Saxony-Anhalt, Germany. It is situated on the left bank of the Elbe, approx. southeast of Magdeburg. For much of the twentieth century it was noted for its large salt mine. The manor house of Schönebeck was owned by Count Heinrich von Blumenthal, Mayor of Magdeburg, until 1810. The firm of Sellier & Bellot opened a munitions factory there in the 1829. Geography The town Schönebeck consists of Schönebeck proper and three ''Ortschaften'' or municipal divisions, that were independent municipalities until January 2009, when they were absorbed into Schönebeck:Hauptsatzung der Stadt Schönebeck (Elbe) February 2021.

Nitrogen Compounds
The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. It can take several oxidation states; but the most oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts. Nitrogen compounds also have an important role in organic chemistry, as nitrogen is part of proteins, amino acids and adenosine triphosphate. Dinitrogen complexes The first example of a dinitrogen complex to be discovered was u(NH3)5(N2)sup>2+ (see figure at right), and soon many other such complexes were discovered. These complexes, in which a nitrogen molecule donates at least one lone pair of electrons to a central metal cation, illustrate how N2 might bind to the metal(s) in nitrogenase and the catalyst for the Haber process: these processes involving dinitrogen activation are vitally important in biology and in the production of fertilisers. Dinitrogen is able to coordinate to metals i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Schönebeck
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

19th-century German Zoologists
The 19th (nineteenth) century began on 1 January 1801 (Roman numerals, MDCCCI), and ended on 31 December 1900 (Roman numerals, MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolitionism, abolished in much of Europe and the Americas. The Industrial Revolution, First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Gunpowder empires, Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost ...

Academic Staff Of The University Of Kiel
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leipzig
Leipzig ( , ; Upper Saxon: ) is the most populous city in the German state of Saxony. Leipzig's population of 605,407 inhabitants (1.1 million in the larger urban zone) as of 2021 places the city as Germany's eighth most populous, as well as the second most populous city in the area of the former East Germany after (East) Berlin.

Plankton
Plankton are the diverse collection of organisms found in Hydrosphere, water (or atmosphere, air) that are unable to propel themselves against a Ocean current, current (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales. Marine plankton include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. Freshwater plankton are similar to marine plankton, but are found in the freshwaters of lakes and rivers. Plankton are usually thought of as inhabiting water, but there are also airborne versions, the aeroplankton, that live part of their lives drifting in the atmosphere. These include plant spores, pollen and wind-scattered seeds, as well as microorganisms swept into the air from terrestrial dust storms and oceanic plankton swept into the air ...
