Danish-American
Danish Americans ( da, Dansk-amerikanere) are Americans who have ancestral roots originated fully or partially from Denmark. There are approximately 1,300,000 Americans of Danish origin or descent. History The first Dane known to have arrived in North America was The Reverend Rasmus Jensen, a priest of the Church of Denmark (Evangelical-Lutheran). He was the chaplain aboard an expedition to the New World commissioned by King Christian IV of Denmark in 1619. The expedition was made up of two small Danish ships Enhiørningen and Lamprenen, with 64 sailors who were Danes, Norwegians, Swedes, and Germans. Captained by the navigator and explorer, Jens Munk, the ships were searching for the Northwest Passage. After sailing into Frobisher Bay and Ungava Bay, Munk eventually passed through Hudson Strait and reached Digges Island (at the northern tip of Quebec) on August 20. They then set out across the Bay towards the southwest. By early September, they had not yet found a passage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monument
A monument is a type of structure that was explicitly created to commemorate a person or event, or which has become relevant to a social group as a part of their remembrance of historic times or cultural heritage, due to its artistic, historical, political, technical or architectural importance. Some of the first monuments were dolmens or menhirs, megalithic constructions built for religious or funerary purposes. Examples of monuments include statues, (war) memorials, historical buildings, archaeological sites, and cultural assets. If there is a public interest in its preservation, a monument can for example be listed as a UNESCO World Heritage Site. Etymology It is believed that the origin of the word "monument" comes from the Greek ''mnemosynon'' and the Latin ''moneo'', ''monere'', which means 'to remind', 'to advise' or 'to warn', however, it is also believed that the word monument originates from an Albanian word 'mani men' which in Albanian language means 'remembe ...

International Congress Of Genetics
The International Congress of Genetics (ICG) is a five yearly conference for geneticists. The first ICG was held in 1898. Since 1973 It has been organized by the International Genetics Federation (IGF). The aim of the congress is to reflect on progress made in genetics, to celebrate the best of contemporary research and to anticipate future developments in the discipline. It is one of the most important genetics meetings, presenting all subfields of the discipline. These subfields cover all present-day experiments using the powerful genomic technologies. Also, the benefits and wider implications of genetic research to societies at large are explored. The Congress has been held in many major cities around the world, such as London, New York City, Paris, Ithaca, Edinburgh, Stockholm, Bellagio, Montreal, The Hague, Tokyo, Berkeley, Moscow, New Delhi, Toronto, Birmingham, Beijing, Melbourne, Berlin and Singapore. The last International Congress of Genetics took place in Singapore in 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louisiana Purchase Exposition
The Louisiana Purchase Exposition, informally known as the St. Louis World's Fair, was an World's fair, international exposition held in St. Louis, Missouri, United States, from April 30 to December 1, 1904. Local, state, and federal funds totaling $15 million were used to finance the event. More than 60 countries and 43 of the then-45 American states maintained exhibition spaces at the fair, which was attended by nearly 19.7 million people. Historians generally emphasize the prominence of the themes of Race (human categorization), race and imperialism, and the fair's long-lasting impact on intellectuals in the fields of history, art history, architecture and anthropology. From the point of view of the memory of the average person who attended the fair, it primarily promoted entertainment, consumer goods and popular culture. The monumental Greco-Roman architecture of this and other fairs of the era did much to influence permanent new buildings and master plans of major cities. ...

Albert Etter
Albert Etter (1872–1950) was an American plant breeder best known for his work on strawberry and apple varieties. Early life and education Albert Felix Etter was born near Shingle Springs in El Dorado County, California, on November 27, 1872. He was one of ten surviving children of the Swiss-born Benjamin Etter (d. 1889), all but one of whom were boys. Around 1876 the family moved to Humboldt County, where Benjamin acquired a farm near Ferndale and became the first person to grow lentils in the county. Development of Ettersburg Albert's German-born mother, Wilhelmina (Kern) Etter (d. 1913) was skilled at cultivating plants, and Etter showed a talent for hybridizing plants in childhood, working with apples, peaches, dahlias, and strawberries by the time he was twelve. He attended public school and by the end of his teens was looking out for a site where he could continue his plant-breeding experiments. On a fishing trip to the Mattole River Valley, he found a section of land ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malus Niedzwetskyana
''Malus niedzwetzkyana'', or Niedzwetzky's apple, is a kind of apple native to certain parts of China, Afghanistan, Kazakhstan, Kyrgyzstan, and Uzbekistan noted for its red-fleshed, red-skinned fruit and red flowers. Some botanists consider it a distinct species, while others have argued it is simply an unusual variety of the common apple, ''Malus pumila''. Niedzwetzky's apple is rare, often growing as an isolated tree, and is endangered throughout its range by agricultural encroachment and logging operations. Only 111 specimens of the tree are known to survive in Kyrgyzstan. The conservation group Fauna & Flora International is working to save and restore the species in that country, and has put ''M. niedzwetzkyana'' on its endangered list, brought it under its Global Trees Campaign, and planted over 1000 saplings in area forests in 2010 and 2011 The tree was introduced to the West c. 1890 by Georg Dieck at the Zöschen Arboretum, Germany, who grew it from seed sent by the Russ ...

Plums
A plum is a fruit of some species in ''Prunus'' subg. ''Prunus''''.'' Dried plums are called prunes. History Plums may have been one of the first fruits domesticated by humans. Three of the most abundantly cultivated species are not found in the wild, only around human settlements: ''Prunus domestica'' has been traced to East European and Caucasian mountains, while ''Prunus salicina'' and '' Prunus simonii'' originated in China. Plum remains have been found in Neolithic age archaeological sites along with olives, grapes and figs. According to Ken Albala, plums originated in Iran. They were brought to Britain from Asia. An article on plum tree cultivation in Andalusia (southern Spain) appears in Ibn al-'Awwam's 12th-century agricultural work, ''Book on Agriculture''. Etymology and names The name plum derived from Old English ''plume'' "plum, plum tree", borrowed from Germanic or Middle Dutch, derived from Latin ' and ultimately from Ancient Greek ''proumnon'', itself belie ...

Apricots
An apricot (, ) is a fruit, or the tree that bears the fruit, of several species in the genus ''Prunus''. Usually, an apricot is from the species '' P. armeniaca'', but the fruits of the other species in ''Prunus'' sect. ''Armeniaca'' are also called apricots. Etymology ''Apricot'' first appeared in English in the 16th century as ''abrecock'' from the Middle French ''aubercot'' or later ''abricot'', from Spanish '' albaricoque'' and Catalan ''a(l)bercoc'', in turn from Arabic الْبَرْقُوق (al-barqūq, "the plums"), from Byzantine Greek βερικοκκίᾱ (berikokkíā, "apricot tree"), derived from late Greek ''πραικόκιον'' (''praikókion'', "apricot") from Latin '' ersica ("peach")praecocia'' (''praecoquus'', "early ripening"). Species Apricots are species belonging to ''Prunus'' sect. ''Armeniaca''. The taxonomic position of '' P. brigantina'' is disputed. It is grouped with plum species according to chloroplast DNA sequences, but more closely r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brome Grass
''Bromus'' is a large genus of grasses, classified in its own tribe Bromeae. They are commonly known as bromes, brome grasses, cheat grasses or chess grasses. Estimates in the scientific literature of the number of species have ranged from 100 to 400, but plant taxonomists currently recognize around 160–170 species. ''Bromus'' is part of the cool-season grass lineage (subfamily Pooideae), which includes about 3300 species. Within Pooideae, ''Bromus'' is classified in tribe Bromeae (it is the only genus in the tribe). ''Bromus'' is closely related to the wheat-grass lineage (tribe Triticeae) that includes such economically important genera as ''Triticum'' (wheat), ''Hordeum'' (barley) and ''Secale'' (rye). Etymology The generic name ''Bromus'' is derived from the Latin ''bromos'', a borrowed word from the Ancient Greek (). and mean ''oats'', but seems to have referred specifically to ''Avena sativa'' (Hippocrates ''On Regimen in Acute Diseases'' 2.43, Dioscorides Medi ...

Crested Wheat Grass
''Agropyron cristatum'', the crested wheat grass, crested wheatgrass, fairway crested wheat grass, is a species in the family Poaceae. This plant is often used as forage and erosion control. It is well known as a widespread introduced species on the prairies of the United States and Canada. History ''Agropyron cristatum'' is one of several closely related grass species referred to as crested wheatgrass. It is unable to hybridize with its similar relatives, as it is a diploid species, whereas its closest relative, ''Agropyron desertorum'', is a tetraploid species.Hanson, A.A. 1972. Grass varieties in the United States. USDA Agricultural Handbook No.170 It was introduced from Russia and Siberia to North America in the first half of the twentieth century, and widely used to reseed abandoned marginal cropland undergoing varying degrees of soil erosion and secondary succession.Rosiere, R.E.
