Ludwig Meyn
Ludwig Meyn (1 October 1820, Pinneberg − 4 November 1878, Uetersen), was a German agricultural scientist, soil scientist, geologist, journalist and mineralogist. He was the pioneer of oil production. Life Meyn was born in Pinneberg, the son of Adolf Meyn, general practitioner and later professor and director of the Clinical Institute of the University of Kiel and attended the public school in Pinneberg from 1826. After the move to Kiel in 1840, he started a degree in natural sciences in Berlin, where he also assisted the chemist Richard Felix Marchand. As a private instructor for rock and soil science, he taught at the Christian-Albrechts University in Kiel, while also working as a teacher of natural sciences at Kiel High School. There he promoted natural and local history. The exploration of the underlying geological structure in his home country and dissemination of research results was his goal. He taught his students the importance of agricultural chemistry, founded by Just ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agricultural Chemistry
Agricultural chemistry is the study of chemistry, especially organic chemistry and biochemistry, as they relate to agriculture—agricultural production, the processing of raw products into foods and beverages, and environmental monitoring and remediation. These studies emphasize the relationships between plants, animals and bacteria and their environment. As a branch of agricultural science, agricultural chemistry studies the chemical compositions and reactions involved in the production, protection, and use of crops and livestock. Its basic science aspects embrace, in addition to test-tube chemistry, all the life processes through which humans obtain food and fiber for themselves and feed for their animals. Its applied science and technology aspects are directed toward control of those processes to increase yields, improve quality, and reduce costs. One important branch of it, chemurgy, is concerned chiefly with utilization of agricultural products as chemical raw materials. Sci ...

Dithmarschen
Dithmarschen (, Northern Low Saxon, Low Saxon: ; archaic English: ''Ditmarsh''; da, Ditmarsken; la, label=Medieval Latin, Tedmarsgo) is a district in Schleswig-Holstein, Germany. It is bounded by (from the north and clockwise) the districts of Nordfriesland, Schleswig-Flensburg, Rendsburg-Eckernförde, and Steinburg, by the state of Lower Saxony (district of Stade (district), Stade, from which it is separated by the Elbe river), and by the North Sea. From the 13th century up to 1559 Dithmarschen was an independent peasant republic within the Holy Roman Empire and a member of the Hanseatic League. Geography The district is located on the North Sea. It is embraced by the Elbe estuary to the south and the Eider (river), Eider estuary to the north. Today it forms a kind of artificial island, surrounded by the Eider river in the north and the Kiel Canal in both the east and southeast. It is a rather flat countryside that was once full of fens and swamps. To the north it borders on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schleswig-Holstein
Schleswig-Holstein (; da, Slesvig-Holsten; nds, Sleswig-Holsteen; frr, Slaswik-Holstiinj) is the northernmost of the 16 states of Germany, comprising most of the historical duchy of Holstein and the southern part of the former Duchy of Schleswig. Its capital city is Kiel; other notable cities are Lübeck and Flensburg. The region is called ''Slesvig-Holsten'' in Danish and pronounced . The Low German name is ''Sleswig-Holsteen'', and the North Frisian name is ''Slaswik-Holstiinj''. In more dated English, it is also known as ''Sleswick-Holsatia''. Historically, the name can also refer to a larger region, containing both present-day Schleswig-Holstein and the former South Jutland County (Northern Schleswig; now part of the Region of Southern Denmark) in Denmark. It covers an area of , making it the 5th smallest German federal state by area (including the city-states). Schleswig was under Danish control during the Viking Age, but in the 12th century it escaped full control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Segeberger Kalkberg
The Kalkberg (lit. "chalk mountain") is a 91-metre-high rock in the center of Bad Segeberg. The name is a misnomer as it is not made of limestone (calcium carbonate), but from gypsum (calcium sulfate). Geology The gypsum was formed as sulfate evaporite sediments, which were deposited about 250 million years ago by the Zechstein Sea. Smaller disturbances in the more recent epochs of earth history allowed the less dense Zechstein salts to flow together and force their way upwards from a great depth into the younger overlying rocks to a level near that of the present-day surface. Under the Kalkberg is a salt dome, which rises by one to two millimeters a year. The red cliffs of Heligoland or the Münsterdorfer Geestinsel are limestone, one of the few formations in Schleswig-Holstein which was not created by the ice ages. The mining of the salt dome ended in 1860. From the salt dome comes the brine feeding the saltwater bath that give Bad Segeberg its name. History Originally, th ...

Lime (material)
Lime is a calcium-containing inorganic material composed primarily of oxides and hydroxide, usually calcium oxide and/or calcium hydroxide. It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. The word ''lime'' originates with its earliest use as building mortar and has the sense of ''sticking or adhering''. These materials are still used in large quantities as building and engineering materials (including limestone products, cement, concrete, and mortar), as chemical feedstocks, and for sugar refining, among other uses. Lime industries and the use of many of the resulting products date from prehistoric times in both the Old World and the New World. Lime is used extensively for wastewater treatment with ferrous sulfate. The rocks and minerals from which these materials are derived, typ ...

Gypsum
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula . It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard or sidewalk chalk, and drywall. Alabaster, a fine-grained white or lightly tinted variety of gypsum, has been used for sculpture by many cultures including Ancient Egypt, Mesopotamia, Ancient Rome, the Byzantine Empire, and the Nottingham alabasters of Medieval England. Gypsum also crystallizes as translucent crystals of selenite. It forms as an evaporite mineral and as a hydration product of anhydrite. The Mohs scale of mineral hardness defines gypsum as hardness value 2 based on scratch hardness comparison. Etymology and history The word ''gypsum'' is derived from the Greek word (), "plaster". Because the quarries of the Montmartre district of Paris have long furnished burnt gypsum (calcined gypsum) used for various purposes, this dehydrated gypsum became known ...

Stroke
A stroke is a medical condition in which poor blood flow to the brain causes cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. A hemorrhagic stroke may also be associated with a severe headache. The symptoms of a stroke can be permanent. Long-term complications may include pneumonia and loss of bladder control. The main risk factor for stroke is high blood pressure. Other risk factors include high blood cholesterol, tobacco smoking, obesity, diabetes mellitus, a previous TIA, end-st ...
