Gustavs Vanags
Gustavs Vanags (10 March 1891 — 8 May 1965) was a Soviet and Latvian organic chemist, full member of Latvian SSR Academy of Sciences. He was also one of the signers of the Memorandum of Latvian Central Council in 1944. Biography Gustavs Vanags was born in "Rungas" house of the Schnicken (Sniķeru) manor (now in Ukri Parish, Auce Municipality). He received primary education in the Mitau Classic Gymnasium, and in 1910 enrolled Riga Polytechnic Institute. During the First World War, he, among many, went in evacuation to the inner regions of Russian Empire; after returning from it in 1921, he completed his education in the new-founded University of Latvia and worked at the Faculty of Chemistry, raising to the position of the chair of the Department of organic chemistry. He received his habilitation in 1932. After Riga Polytechnic Institute was reestablished in 1958, G. Vanags moved to it, serving in the same position as the department chair until 1965.

Žagarė
Žagarė (, see also other names) is a city located in the Joniškis district, northern Lithuania, close to the border with Latvia. It has a population of about 2,000, down from 14,000 in 1914, when it was the 7th largest city in Lithuania. Žagarė is famous for ''Žagarvyšnė'' - a cherry species originated in Žagarė. Etymology Žagarė's name is probably derived from the Lithuanian word ''žagaras,'' meaning "twig". Other renderings of the name include: lv, Žagare, pl, Żagory, yi, זאַגער, translit=Zager. History The foundation of Žagarė dates back to the 12th century. A settlement of the Baltic tribe Semigallians ''Sagera'' was mentioned for the first time in March 1254 in the documents of the partitioning of the Semigallia. In 13th century it was a Semigalian fortress ''Raktuvė'' (or ''Raktė'', first mentioned in 1272-1289 documents). It was an important centre of Semigallian warriors, who fought against the Livonian Brothers of the Sword and the Livonia ...

People From Auce Municipality
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 p ...

Riga Technical University
Riga Technical University (RTU) ( lv, Rīgas Tehniskā universitāte) is the oldest technical university in the Baltic countries established on October 14, 1862. It is located in Riga, Latvia and was previously known as 'Riga Polytechnical Institute' and 'Riga Polytechnicum'. History Riga Polytechnical Institute (1862–1918) Riga Polytechnicum was first established in 1862 and was the first poly technical institute in Imperial Russia. It offered degrees in agriculture, chemistry, engineering, mechanics, trade and architecture, with education in German. In addition to four technical faculties (architecture, engineering, mechanical engineering, chemistry), the polytechnic also included an agricultural and a commercial faculty. The first lecturers came from Germany, Switzerland and Austria-Hungary. The language of instruction was German. Between 1863 and 1869, the number of students grew from sixteen to ninety. In 1869 the polytechnic moved into a new building. Since there was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest Cemetery, Riga
Forest Cemetery ( lv, Rīgas Meža kapi) is an large cemetery in the northwestern part of Riga, the capital of Latvia, between the neighbourhoods of Mežaparks and Čiekurkalns. Formally, the cemetery is divided between 1st Forest Cemetery, with entrance from Aizsaules Street, and 2nd Forest Cemetery, with entrance from Gaujas Street. In 1904, German Lutheran congregations in Riga inquired the Riga City Council for allotment of land for a cemetery in the Mežaparks neighbourhood. It was planned to become a new large cemetery after the Great Cemetery, that was established 1773 in Riga and had exhausted its potential. The prominent Baltic-German landscape architect Georg Kuphaldt was author of the original construction project presented 1908, which should have appeared as a park with a central via funeralis, with many small and lateral paths along the graves with low fences and small monuments. The Forest Cemetery was established 29 July 1910 following a decision made by the 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diphenadione
Diphenadione is a vitamin K antagonist that has anticoagulant effects and is used as a rodenticide against rats, mice, voles, ground squirrels and other rodents. The chemical compound is an anti-coagulant with active half-life longer than warfarin and other synthetic 1,3-indandione anticoagulants.Meister, R.T. (ed.). 1992. Farm Chemicals Handbook '92.

Dicarbonyl
In organic chemistry, a dicarbonyl is a molecule containing two carbonyl () groups. Although this term could refer to any organic compound containing two carbonyl groups, it is used more specifically to describe molecules in which both carbonyls are in close enough proximity that their reactivity is changed, such as 1,2-, 1,3-, and 1,4-dicarbonyls. Their properties often differ from those of monocarbonyls, and so they are usually considered functional groups of their own. These compounds can have symmetrical or unsymmetrical substituents on each carbonyl, and may also be functionally symmetrical (dialdehydes, diketones, diesters, ''etc.'') or unsymmetrical (keto-esters, keto-acids, ''etc.''). 1,2-Dicarbonyls 1,2-Dialdehyde The only 1,2-dialdehyde is glyoxal, . Like many alkyldialdehydes, glyoxal is encountered almost exclusively as its hydrate and oligomers thereof. These derivatives often behave equivalently to the aldehydes since hydration is reversible. Glyoxal condenses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habilitation
Habilitation is the highest university degree, or the procedure by which it is achieved, in many European countries. The candidate fulfills a university's set criteria of excellence in research, teaching and further education, usually including a dissertation. The degree, abbreviated "Dr. habil." (Doctor habilitatus) or "PD" (for "Privatdozent"), is a qualification for professorship in those countries. The conferral is usually accompanied by a lecture to a colloquium as well as a public inaugural lecture. History and etymology The term ''habilitation'' is derived from the Medieval Latin , meaning "to make suitable, to fit", from Classical Latin "fit, proper, skillful". The degree developed in Germany in the seventeenth century (). Initially, habilitation was synonymous with "doctoral qualification". The term became synonymous with "post-doctoral qualification" in Germany in the 19th century "when holding a doctorate seemed no longer sufficient to guarantee a proficient transfe ...
