Nikolaus Joseph Von Jacquin
Nikolaus Joseph Freiherr von Jacquin (16 February 172726 October 1817) was a scientist who studied medicine, chemistry and botany. Biography Born in Leiden in the Netherlands, he studied medicine at Leiden University, then moved first to Paris and afterward to Vienna. In 1752, he studied under Gerard van Swieten in Vienna. Between 1755 and 1759, Jacquin was sent to the West Indies, Central America, Venezuela and New Granada by Francis I to collect plants for the Schönbrunn Palace, and amassed a large collection of animal, plant and mineral samples. In 1797, Alexander von Humboldt profited from studying these collections and conversing with Jacquin in preparation of his own journey to the Americas. In 1763, Jacquin became professor of chemistry and mineralogy at the Bergakademie Schemnitz (now Banská Štiavnica in Slovakia). In 1768, he was appointed Professor of Botany and Chemistry and became director of the botanical gardens of the University of Vienna. For his work ...

α-pinene
α-Pinene is an organic compound of the terpene class, one of two isomers of pinene. It is an alkene and it contains a reactive four-membered ring. It is found in the oils of many species of many coniferous trees, notably the pine. It is also found in the essential oil of rosemary (''Rosmarinus officinalis'') and ''Satureja myrtifolia'' (also known as ''Zoufa'' in some regions). Both enantiomers are known in nature; (1''S'',5''S'')- or (−)-α-pinene is more common in European pines, whereas the (1''R'',5''R'')- or (+)-α-isomer is more common in North America. The racemic mixture is present in some oils such as eucalyptus oil and orange peel oil. Reactivity : Commercially important derivatives of alpha-pinene are linalool, geraniol, nerol, a-terpineol, and camphene. α-Pinene 1 is reactive owing to the presence of the four-membered ring adjacent to the alkene. The compound is prone to skeletal rearrangements such as the Wagner–Meerwein rearrangement. Acids typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Africa
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Luo Dialect
The Dholuo dialect (pronounced ) or ''Nilotic Kavirondo'', is a dialect of the Luo group of Nilotic languages, spoken by about 4.2 million Luo people of Kenya and Tanzania, who occupy parts of the eastern shore of Lake Victoria and areas to the south. It is also spoken by millions in Uganda, South Sudan, and Ethiopia. It is used for broadcasts on KBC (Kenya Broadcasting Corporation, formerly the ''Voice of Kenya''). Dholuo is mutually intelligible with Alur, Lango, Acholi and Adhola of Uganda. Dholuo and the aforementioned Uganda languages are all linguistically related to Jur chol of South Sudan and Anuak of Ethiopia due to common ethnic origins of the larger Luo peoples who speak Luo languages. It is estimated that Dholuo has 90% lexical similarity with Lep Alur (Alur), 83% with Lep Achol (Acholi), 81% with Lango, and 93% with Dhopadhola (Adhola). However, these are often counted as separate languages despite common ethnic origins due to linguistic shift occasioned by ...

Sotho Language
Sotho () or Sesotho () or Southern Sotho is a Southern Bantu language of the Sotho–Tswana ("S.30") group, spoken primarily by the Basotho in Lesotho, where it is the national and official language; South Africa (particularly the Free State), where it is one of the 11 official languages; and in Zimbabwe where it is one of 16 official languages.

Classification Sotho is a Southern Bantu language, belonging to the Niger–Congo language family within the Sotho-Tswana branch of Zone S (S.30). Although Southern Sotho shares the name ''Sotho'' with Northern Sotho, the two groups have less in common with each other than they have with Setswana. "Sotho" is also the name given to the entire Sotho-Tswana group, in which case Sesotho proper is called "Southern Sotho". Within the Sotho-Tswana group, Southern Sotho is most ...

Zulu Language
Zulu (), or isiZulu as an endonym, is a Southern Bantu language of the Nguni branch spoken in Southern Africa. It is the language of the Zulu people, with about 12 million native speakers, who primarily inhabit the province of KwaZulu-Natal of South Africa. Zulu is the most widely spoken home language in South Africa (24% of the population), and it is understood by over 50% of its population. It became one of South Africa's 11 official languages in 1994. According to Ethnologue, it is the second-most-widely spoken of the Bantu languages, after Swahili. Like many other Bantu languages, it is written with the Latin alphabet. In South African English, the language is often referred to in its native form, ''isiZulu''.

Xhosa Language
Xhosa (, ) also isiXhosa as an endonym, is a Nguni language and one of the official languages of South Africa and Zimbabwe. Xhosa is spoken as a first language by approximately 8.2 million people and by another 11 million as a second language in South Africa, mostly in Eastern Cape, Western Cape, Northern Cape and Gauteng.

Classification Xhosa is part of the branch of Nguni languages, which also include Zulu, Southern Ndebele and Northern Ndebele. Nguni languages effectively form a dialect continuum of variously mutually intelligible varieties. Xhosa is, to some extent, mutually intelligible with Zulu and with other Nguni languages to a lesser extent. Nguni languages are, in turn, classified under the much larger abstraction of Bantu languages. Geographical distribution ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afrikaans
Afrikaans (, ) is a West Germanic language that evolved in the Dutch Cape Colony from the Dutch vernacular of Holland proper (i.e., the Hollandic dialect) used by Dutch, French, and German settlers and their enslaved people. Afrikaans gradually began to develop distinguishing characteristics during the course of the 18th century. Now spoken in South Africa, Namibia and (to a lesser extent) Botswana, Zambia, and Zimbabwe, estimates circa 2010 of the total number of Afrikaans speakers range between 15 and 23 million. Most linguists consider Afrikaans to be a partly creole language. An estimated 90 to 95% of the vocabulary is of Dutch origin with adopted words from other languages including German and the Khoisan languages of Southern Africa. Differences with Dutch include a more analytic-type morphology and grammar, and some pronunciations. There is a large degree of mutual intelligibility between the two languages, especially in written form. About 13.5% of the South ...
