Johann Zacherl
Johann Zacherl (1814 – 30 June 1888) was an Austrian inventor, industrialist and manufacturer who made a fortune in the late 19th century selling dried flower heads of ''Chrysanthemum cinerariifolium'' as an insecticide. Biography Zacherl was born in Munich (Germany) in 1814. After finishing his studies, he left Munich to visit Vienna, St Petersburg and Odessa. He eventually reached Tiflis in the Caucasus, where he discovered villagers used a natural insecticide, Pyrethrum, against vermin. He began to develop the powder's trade with Austria in 1842. The powder received different names: Lowizachek (in Armenia), Bug Flower, Powder of Persia and Persian insect powder. After a longer stay in Tiflis, in 1855 he established his company, ''Mottenfraß-Versicherungsunternehmung Johann Zacherl'', in Vienna's 19th district, and began selling the insect repellent ''Zacherlin''. With the help of his son, Johann Evangelist, he developed the Pyrethrum product line. Zacherl died in Vien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pyrethrum
''Pyrethrum'' was a genus of several Old World plants now classified as ''Chrysanthemum'' or ''Tanacetum'' which are cultivated as ornamentals for their showy flower heads. Pyrethrum continues to be used as a common name for plants formerly included in the genus ''Pyrethrum''. Pyrethrum is also the name of a natural insecticide made from the dried flower heads of '' Chrysanthemum cinerariifolium'' and ''Chrysanthemum coccineum''. The insecticidal compounds present in these species are pyrethrins. Description Some members of the genus ''Chrysanthemum'', such as the following two, are placed in the genus ''Tanacetum'' instead by some botanists. Both genera are members of the daisy (or aster) family, Asteraceae. They are all perennial plants with a daisy-like appearance and white petals. * '' Tanacetum cinerariifolium'' is called the Dalmatian chrysanthemum, denoting its origin in that region of the Balkans (Dalmatia). It looks more like the common daisy than other pyrethrums do. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berliner Zeitung
The ''Berliner Zeitung'' (, ''Berlin Newspaper'') is a daily newspaper based in Berlin, Germany. Founded in East Germany in 1945, it is the only East German paper to achieve national prominence since reunification. It is published by Berliner Verlag. History and profile ''Berliner Zeitung'' was first published on 21 May 1945 in East Berlin. The paper, a center-left daily, is published by Berliner Verlag. After the fall of the Berlin Wall, the paper was bought by Gruner + Jahr and the British publisher Robert Maxwell. Gruner + Jahr later became sole owners and relaunched it in 1997 with a completely new design. A stated goal was to turn the ''Berliner Zeitung'' into "Germany's ''Washington Post''". The daily says its journalists come "from east and west", and it styles itself as a "young, modern and dynamic" paper for the whole of Germany. It is the only East German paper to achieve national prominence since reunification. In 2003, the ''Berliner'' was Berlin's largest subscr ...

Bukovina
Bukovinagerman: Bukowina or ; hu, Bukovina; pl, Bukowina; ro, Bucovina; uk, Буковина, ; see also other languages. is a historical region, variously described as part of either Central or Eastern Europe (or both).Klaus Peter BergerThe Creeping Codification of the New Lex Mercatoria Kluwer Law International, 2010, p. 132 The region is located on the northern slopes of the central Eastern Carpathians and the adjoining plains, today divided between Romania and Ukraine. Settled initially and primarily by Romanians and subsequently by Ruthenians (Ukrainians) during the 4th century, it became part of the Kievan Rus' in the 10th century and then the Principality of Moldavia during the 14th century. The region has been sparsely populated since the Paleolithic, with several now extinct peoples inhabiting it. Consequently, the culture of the Kievan Rus' spread in the region, with the Bukovinian Church administered from Kyiv until 1302, when it passed to Halych metropoly. The ...

Christian Social Party (Austria)
The Christian Social Party (german: link=no, Christlichsoziale Partei, CS or CSP) was a major conservative political party in the Cisleithanian crown lands of Austria-Hungary and under the First Austrian Republic, from 1891 to 1934. The party was affiliated with Austrian nationalism that sought to keep Catholic Austria out of the State of Germany founded in 1871, which it viewed as Protestant and Prussian-dominated; it identified Austrians on the basis of their predominantly Catholic religious identity as opposed to the predominantly Protestant religious identity of the Prussians. History Foundation The party emerged in the run-up to the 1891 Imperial Council (''Reichsrat'') elections under the populist Vienna politician Karl Lueger (1844–1910). Referring to ideas developed by the Christian Social movement under Karl von Vogelsang (1818–1890) and the Christian Social Club of Workers, it was oriented towards the petit bourgeoisie and clerical-Catholic; there were ma ...

Historically, they were a semi-nomadic and semi-militarized people, who, while under the nominal suzerainty of various Eastern European states at the time, were allowed a great degree of self-governance in exchange for military service. Although numerous linguistic and religious groups came together to form the Cossacks, most of them coalesced and became East Slavic-speaking Orthodox Christians. The Cossacks were particularly noted for holding democratic traditions. The rulers of the Polish-Lithuanian Commonwealth and Russian Empire endowed Cossacks with certain spe ...

Spirit Of Wine
''Aqua vitae'' (Latin for "water of life") or aqua vita is an archaic name for a concentrated aqueous solution of ethanol. These terms could also be applied to weak ethanol without rectification. Usage was widespread during the Middle Ages and the Renaissance, although its origin is likely much earlier. This Latin term appears in a wide array of dialectical forms throughout all lands and people conquered by ancient Rome. The term is a generic name for all types of distillates, and eventually came to refer specifically to distillates of alcoholic beverages (liquors). ''Aqua vitae'' was typically prepared by distilling wine and in English texts was also called ardent spirits, spirit of wine, or spirits of wine, a name that could be applied to brandy that had been repeatedly distilled. The term was used by the 14th-century alchemist John of Rupescissa, who believed the then newly discovered substance of ethanol to be an imperishable and life-giving "fifth essence" or '' quintes ...

Diethyl Ether
Diethyl ether, or simply ether, is an organic compound in the ether class with the formula , sometimes abbreviated as (see Pseudoelement symbols). It is a colourless, highly volatile, sweet-smelling ("ethereal odour"), extremely flammable liquid. It is commonly used as a solvent in laboratories and as a starting fluid for some engines. It was formerly used as a general anesthetic, until non-flammable drugs were developed, such as halothane. It has been used as a recreational drug to cause intoxication. Production Most diethyl ether is produced as a byproduct of the vapor-phase hydration of ethylene to make ethanol. This process uses solid-supported phosphoric acid catalysts and can be adjusted to make more ether if the need arises. Vapor-phase dehydration of ethanol over some alumina catalysts can give diethyl ether yields of up to 95%. Diethyl ether can be prepared both in laboratories and on an industrial scale by the acid ether synthesis. Ethanol is mixed with a stro ...

Rosin
Rosin (), also called colophony or Greek pitch ( la, links=no, pix graeca), is a solid form of resin obtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpene components. It is semi-transparent and varies in color from yellow to black. At room temperature rosin is brittle, but it melts at stove-top temperature. It chiefly consists of various resin acids, especially abietic acid. The term ''colophony'' comes from , Latin for "resin from Colophon" ( grc, Κολοφωνία ῥητίνη, Kolophōnia rhētinē), an ancient Ionic city. Properties Rosin is brittle and friable, with a faint piny odor. It is typically a glassy solid, though some rosins will form crystals, especially when brought into solution. The practical melting point varies with different specimens, some being semi-fluid at the temperature of boiling water, others melting at 100 °C to 120 °C. It is very flammable, burni ...

Tifflis
Tbilisi ( ; ka, თბილისი ), in some languages still known by its pre-1936 name Tiflis ( ), is the capital and the largest city of Georgia, lying on the banks of the Kura River with a population of approximately 1.5 million people. Tbilisi was founded in the 5th century AD by Vakhtang I of Iberia, and since then has served as the capital of various Georgian kingdoms and republics. Between 1801 and 1917, then part of the Russian Empire, Tiflis was the seat of the Caucasus Viceroyalty, governing both the northern and the southern parts of the Caucasus. Because of its location on the crossroads between Europe and Asia, and its proximity to the lucrative Silk Road, throughout history Tbilisi was a point of contention among various global powers. The city's location to this day ensures its position as an important transit route for energy and trade projects. Tbilisi's history is reflected in its architecture, which is a mix of medieval, neoclassical, Beaux Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moth
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well establishe ...
