Jonathan Carl Zenker
Jonathan Carl (or Karl) Zenker (1 March 1799 – 6 November 1837) was a German naturalist born in Sundremda, located in the Saalfeld-Rudolstadt district. Originally a student of theology at the University of Jena, he subsequently devoted his energies to science and medicine. From 1823 he lived in Dresden, later returning to Jena, where on the basis of his dissertation "Batrachomyologia", he became a privat-docent of natural history. In 1828 he became an associate professor of botany and natural history, followed by a full professorship in 1836 (one year prior to his death at the age of 38). A genus of grasses called '' Zenkeria'' is named in his honour. Also, he named the genus of fossil broad-leaf trees ''Credneria'' in honor of Karl August Credner.

David Nathaniel Friedrich Dietrich
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David c ...

19th-century German Botanists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The 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 Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thuringia
Thuringia (; german: Thüringen ), officially the Free State of Thuringia ( ), is a state of central Germany, covering , the sixth smallest of the sixteen German states. It has a population of about 2.1 million. Erfurt is the capital and largest city. Other cities are Jena, Gera and Weimar. Thuringia is bordered by Bavaria, Hesse, Lower Saxony, Saxony-Anhalt, and Saxony. It has been known as "the green heart of Germany" () from the late 19th century due to its broad, dense forest. Most of Thuringia is in the Saale drainage basin, a left-bank tributary of the Elbe. Thuringia is home to the Rennsteig, Germany's best-known hiking trail. Its winter resort of Oberhof makes it a well-equipped winter sports destination – half of Germany's 136 Winter Olympic gold medals had been won by Thuringian athletes as of 2014. Thuringia was favoured by or was the birthplace of three key intellectuals and leaders in the arts: Johann Sebastian Bach, Johann Wolfgang von Goethe, and Fried ...

Christian Eduard Langethal
Christian Eduard Langethal (6 January 1806, Erfurt – 28 July 1878, Jena) was a German botanist and agronomist. He is known for his writings involving agricultural botany and agricultural history. Beginning in 1827 he studied natural sciences at the University of Jena. During the winter term of 1834/35 he began teaching classes in natural history at the recently built scientific academy at Eldena (near Greifswald), where he worked closely with his former teacher, Friedrich Gottlob Schulze (1795–1860). In 1839, with Schulze, he returned to the University of Jena as an associate professor of botany. At Jena he distinguished himself in studies of botany as it applied to agricultural science Agricultural science (or agriscience for short) is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture.

Diederich Franz Leonhard Von Schlechtendal
Diederich Franz Leonhard von Schlechtendal (27 November 1794, Xanten – 12 October 1866, Halle) was a German botanist. He studied in Berlin, in 1819 becoming curator of the Royal Herbarium. He was a professor of botany and director of the Botanical Gardens at the Martin Luther University of Halle-Wittenberg from 1833 until his death in 1866. The genus '' Schlechtendalia'' (Asteraceae), from Brazil, Uruguay and Argentina, was named in his honor. He was editor of the botanical journal ''Linnaea'' (from 1826), and with Hugo von Mohl (1805-1872), was publisher of the ''Botanischen Zeitung'' (from 1843). He conducted important investigations of the then largely unknown flora of Mexico, carried out in conjunction with Adelbert von Chamisso (1781-1838), and based on specimens collected by Christian Julius Wilhelm Schiede (1798-1836) and Ferdinand Deppe (1794-1861).

Bohemia
Bohemia ( ; cs, Čechy ; ; hsb, Čěska; szl, Czechy) is the westernmost and largest historical region of the Czech Republic. Bohemia can also refer to a wider area consisting of the historical Lands of the Bohemian Crown ruled by the Bohemian kings, including Moravia and Czech Silesia, in which case the smaller region is referred to as Bohemia proper as a means of distinction. Bohemia was a duchy of Great Moravia, later an independent principality, a kingdom in the Holy Roman Empire, and subsequently a part of the Habsburg monarchy and the Austrian Empire. After World War I and the establishment of an independent Czechoslovak state, the whole of Bohemia became a part of Czechoslovakia, defying claims of the German-speaking inhabitants that regions with German-speaking majority should be included in the Republic of German-Austria. Between 1938 and 1945, these border regions were joined to Nazi Germany as the Sudetenland. The remainder of Czech territory became the Second ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lignite
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35%, and is considered the lowest rank of coal due to its relatively low heat content. When removed from the ground, it contains a very high amount of moisture which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials may be present in lignite which are left over in the coal fly ash produced from its combustion, further increasing health risks. Characteristics Lignite is brow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
