Montrouge
Montrouge () is a commune in the southern Parisian suburbs, located from the centre of Paris. It is one of the most densely populated municipalities in Europe. After a long period of decline, the population has increased again in recent years. History The name "Montrouge" means Red Mountain - from ''mont'' (mountain) and ''rouge'' (red) - because of the reddish colour of the earth in this area. The name of the community was first mentioned in monastery documents in 1194. Throughout the Middle Ages, the hamlet was home to monasteries and a number of religious orders, while in the 15th century it became the site of quarries used for the reconstruction of Paris. The late sixteenth century saw the plain of Montrouge named "reserve for royal hunts", and during the seventeenth and eighteenth centuries it was known for its windmills, which have all now disappeared. On 1 January 1860, the city of Paris was enlarged by annexing neighbouring communes. On that occasion, most of the commu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Mycologist
Mycology is the branch of biology concerned with the study of fungus, fungi, including their genetics, genetic and biochemistry, biochemical properties, their Taxonomy (biology), taxonomy and ethnomycology, their use to humans, including as a source for tinder, traditional medicine, Edible mushroom, food, and entheogens, as well as their dangers, such as poison, toxicity or fungal infection, infection. A biologist specializing in mycology is called a mycologist. Mycology branches into the field of phytopathology, the study of plant diseases, and the two disciplines remain closely related because the vast majority of plant pathogens are fungi. Overview Historically, mycology was a branch of botany because, although fungi are evolutionarily more closely related to animals than to plants, this was not recognized until a few decades ago. Pioneer mycologists included Elias Magnus Fries, Christian Hendrik Persoon, Anton de Bary, Elizabeth Eaton Morse, and Lewis David von Schweinitz ...

Plant Pathologist
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungus, fungi, oomycetes, bacterium, bacteria, plant virus, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other Plant defense against herbivory, pests that affect plant health by eating Plant tissue, plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, wat ...

Institut National Agronomique Paris Grignon
The Institut National Agronomique Paris-Grignon (INA P-G) was a French university-level institution of grande école-type. It offered master's degree in agricultural- and life sciences. It was created in 1971 by merging the ''Institut national agronomique'' (Paris) and the ''École nationale supérieure d'Agronomie de Grignon'', thus having a history that goes back to 1826. INA P-G disappeared as an administrative entity on January 1, 2007, along with ENSIA and ENGREF, to create AgroParisTech.

Aspergillus Nidulans
''Aspergillus nidulans'' (also called ''Emericella nidulans'' when referring to its sexual form, or teleomorph) is one of many species of filamentous fungi in the phylum Ascomycota. It has been an important research organism for studying eukaryotic cell biology for over 50 years, being used to study a wide range of subjects including recombination, DNA repair, mutation, cell cycle control, tubulin, chromatin, nucleokinesis, pathogenesis, metabolism, and experimental evolution. It is one of the few species in its genus able to form sexual spores through meiosis, allowing crossing of strains in the laboratory. ''A. nidulans'' is a homothallic fungus, meaning it is able to self-fertilize and form fruiting bodies in the absence of a mating partner. It has septate hyphae with a woolly colony texture and white mycelia. The green colour of wild-type colonies is due to pigmentation of the spores, while mutations in the pigmentation pathway can produce other spore colours. Genome The ' ...

Édouard Ernest Prillieux
Édouard Ernest Prillieux (11 January 1829 in Paris – 7 October 1915 in Mondoubleau) was a French botanist and agronomist known for his work with plant diseases. He took courses at the Muséum National d'Histoire Naturelle as a pupil of Adrien-Henri de Jussieu and Adolphe-Théodore Brongniart, then from 1850 studied botany at the Institut national agronomique in Versailles under Pierre Étienne Simon Duchartre. For a number of years afterwards he served in various functions at the Sorbonne and at the natural history museum. From 1874 he taught classes at the École Centrale des Arts et Manufactures,BHL Taxonomic literature : a selective guide to botanical publications and in 1876 was named a professor of botany and |
Juglans
Walnut trees are any species of tree in the plant genus ''Juglans'', the type genus of the family Juglandaceae, the seeds of which are referred to as walnuts. All species are deciduous trees, tall, with pinnate leaves , with 5–25 leaflets; the shoots have chambered pith, a character shared with the wingnuts (''Pterocarya''), but not the hickories (''Carya'') in the same family. The 21 species in the genus range across the north temperate Old World from southeast Europe east to Japan, and more widely in the New World from southeast Canada west to California and south to Argentina. Edible walnuts, which are consumed worldwide, are usually harvested from cultivated varieties of the species ''Juglans regia''. China produces half of the world total of walnuts. Etymology The common name ''walnut'' derives from Old English ''wealhhnutu'', literally 'foreign nut' (from ''wealh'' 'foreign' + ''hnutu'' 'nut'), because it was introduced from Gaul and Italy. The Latin name for the wal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coffee
Coffee is a drink prepared from roasted coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulant, stimulating effect on humans, primarily due to its caffeine content. It is the most popular hot drink in the world. Seeds of the ''Coffea'' plant's fruits are separated to produce unroasted green coffee beans. The beans are Coffee roasting, roasted and then ground into fine particles that are typically steeped in hot water before being filtered out, producing a cup of coffee. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often used to mask the bitter taste or enhance the flavor. Though coffee is now a global commodity, it has a History of coffee, long history tied closely to food traditions around the Red Sea. The earliest credible evidence of coffee d ...
