Oosterhout
Oosterhout (; from ''ooster'', "eastern", and ''hout'', "woods") is a municipality and a city in the southern Netherlands. The municipality had a population of in . Population centers The municipality of Oosterhout includes the following places: History Oosterhout is mentioned for the first time in 1277, although archaeological excavations showed the existence of human settlements in the area in prehistoric times. The Knights Templar had a temple here dedicated to St. John the Baptist. It was home to a castle which later acquired control over the surrounding area, up to Breda and Bergen op Zoom. The castle was destroyed by Spanish troops during the Eighty Years War, in 1573; only a tower of it survives today. The city became the seat of a flourishing ceramics industry, which lasted until the 19th century. In 1625 the city was besieged by Frederick Henry, Prince of Orange, and suffered heavy damage. Despite the rise of Protestantism, it was home to several Catholic monast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java
Java (; id, Jawa, ; jv, ꦗꦮ; su, ) is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea to the north. With a population of 151.6 million people, Java is the world's List of islands by population, most populous island, home to approximately 56% of the Demographics of Indonesia, Indonesian population. Indonesia's capital city, Jakarta, is on Java's northwestern coast. Many of the best known events in Indonesian history took place on Java. It was the centre of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the History of Indonesia, Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally. Four of Indonesia's eight UNESCO world heritage sites are located in Java: Ujung Kulon National Park, Borobudur Temple, Prambanan Temple, and Sangiran Early Man Site. ...

Vriesea
''Vriesea'' is a genus of flowering plants in the botanical family Bromeliaceae, subfamily Tillandsioideae. The genus name is for Willem Hendrik de Vriese, Dutch botanist, physician (1806–1862). Its species are widespread over Mexico, Central America, South America and the West Indies. Containing some of the largest bromeliad species, these tropical plants harbor a wide variety of insect fauna, unlike the smaller ''Catopsis'' species. In the wild, frogs may go through their whole life cycle in a bromeliad. This genus is closely related to ''Guzmania.'' Both ''Guzmania'' and ''Vriesea'' have dry capsules that split open to release parachute like seeds similar to the Dandelion (''Taraxacum'' sp.). Most ''Vriesea'' are epiphytes and grow soil-less on trees. they have no roots but have special hold fasts that do not take in any nutrients. All nutrients are taken in through the center "tank" made by a rosette of leaves. Species , Plants of the World Online accepted the following ...

He is credited with making design improvements to the microscope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degrees such as a bachelor's degree plus an advanced degree like a master's degree or a doctorate. Like other scientists, biologists can be fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marattiaceae
Marattiaceae is the only family of extant (living) ferns in the order Marattiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), Marattiales is the only order in the subclass Marattiidae. The family has six genera and about 110 species. Many are different in appearance from other ferns, having large fronds and fleshy rootstocks. Description The Marattiaceae diverged from other ferns very early in their evolutionary history and are quite different from many plants familiar to people in temperate zones. Many of them have massive, fleshy rootstocks and the largest known fronds of any fern. The Marattiaceae is one of two groups of ferns traditionally known as eusporangiate ferns, meaning that the sporangium is formed from a group of cells as opposed to a leptosporangium in which there is a single initial cell. The large fronds characteristic of the group are most readily found in the genus ''Angiopteris'', native to Australasia, Madagascar and Oceania. These fro ...

Rafflesia
''Rafflesia'' () is a genus of parasitic flowering plants in the family Rafflesiaceae. The species have enormous flowers, the buds rising from the ground or directly from the lower stems of their host plants; one species has the largest flowers in the world. Plants of the World Online lists up to 41 species from this genus, all of them are found throughout Southeast Asia. Western Europeans first learned about plants of this genus from French surgeon and naturalist Louis Deschamps when he was in Java between 1791 and 1794; but his notes and illustrations, seized by the British in 1803, were not available to western science until 1861. The first British person to see one was Joseph Arnold in 1818, in the Indonesia rainforest in Bengkulu, Sumatra, after a Malay servant working for him discovered a flower and pointed it out to him. The flower, and the genus, was later named after Stamford Raffles, the leader of the expedition and the founder of the British colony of Singapore. The f ...

Camphor
Camphor () is a waxy, colorless solid with a strong aroma. It is classified as a terpenoid and a cyclic ketone. It is found in the wood of the camphor laurel ('' Cinnamomum camphora''), a large evergreen tree found in East Asia; and in the kapur tree ( ''Dryobalanops'' sp.), a tall timber tree from South East Asia. It also occurs in some other related trees in the laurel family, notably '' Ocotea usambarensis''. Rosemary leaves (''Rosmarinus officinalis'') contain 0.05 to 0.5% camphor, while camphorweed (''Heterotheca'') contains some 5%. A major source of camphor in Asia is camphor basil (the parent of African blue basil). Camphor can also be synthetically produced from oil of turpentine. The compound is chiral, existing in two possible enantiomers as shown in the structural diagrams. The structure on the left is the naturally occurring (+)-camphor ((1''R'',4''R'')-bornan-2-one), while its mirror image shown on the right is the (−)-camphor ((1''S'',4''S'')-bornan-2-one). ...

Vanilla
Vanilla is a spice derived from orchids of the genus ''Vanilla (genus), Vanilla'', primarily obtained from pods of the Mexican species, flat-leaved vanilla (''Vanilla planifolia, V. planifolia''). Pollination is required to make the plants produce the fruit from which the vanilla spice is obtained. In 1837, Belgian botanist Charles François Antoine Morren discovered this fact and pioneered a method of artificially pollinating the plant. The method proved financially unworkable and was not deployed commercially. In 1841, Edmond Albius, a 12-year-old enslaved child who lived on the French island of Réunion in the Indian Ocean, discovered that the plant could be hand-pollination, hand-pollinated. Hand-pollination allowed global cultivation of the plant. Noted French botanist and plant collector Jean Michel Claude Richard falsely claimed to have discovered the technique three or four years earlier. By the end of the 20th century, Albius was considered the true discoverer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cinchona
''Cinchona'' (pronounced or ) is a genus of flowering plants in the family Rubiaceae containing at least 23 species of trees and shrubs. All are native to the Tropical Andes, tropical Andean forests of western South America. A few species are reportedly naturalization (biology), naturalized in Central America, Jamaica, French Polynesia, Sulawesi, Saint Helena in the South Atlantic, and São Tomé and Príncipe off the coast of tropical Africa, and others have been cultivated in India and Java, where they have formed hybrids. ''Cinchona'' has been historically sought after for its medicinal value, as the bark of several species yields quinine and other alkaloids. These were the only effective treatments against malaria during the height of European colonialism, which made them of great economic and political importance. Trees in the genus are also known as fever trees because of their anti-malarial properties. The artificial Quinine total synthesis, synthesis of quinine in 1944 ...

Franz Julius Ferdinand Meyen
Franz Julius Ferdinand Meyen (28 June 1804 – 2 September 1840) was a Prussian physician and botanist. Meyen was born in Tilsit, East Prussia. In 1830 he wrote ''Phytotomie'', the first major study of plant anatomy. Between 1830 and 1832, he took part in an expedition to South America on board the ''Prinzess Luise'', visiting Peru and Bolivia, describing species then new to science such as the Humboldt penguin. From 1823 to 1826, he studied medicine at the University of Berlin, followed by service as a military surgeon at the Charité in Berlin. In 1834 he became an associate professor of botany in Berlin. With Heinrich Friedrich Link, he was co-editor of the journal ''Jahresberichte über die Arbeiten für physiologische Botanik'' (1837–1839).Max Planck Institute for the History of Science, Berlin< ...

Adriaan Van Der Hoop
Adriaan van der Hoop (28 April 1778, in Amsterdam – 17 March 1854, in Amsterdam) was a Dutch banker and in the first half of the 19th century one of the richest men in the Netherlands. He also was an influential politician: a member of the city council, the States-Provincial in Haarlem and the Senate in The Hague. In his later years he became an important art and plant collector. On his death he left 250 paintings to the city of Amsterdam, who could barely pay the inheritance tax. In this way Van der Hoop contributed substantially to the collection of the Rijksmuseum. Life Adriaan van der Hoop was the son of Joan Cornelis van der Hoop, secretary of the Sociëteit van Suriname, prosecutor for the Admiralty of Amsterdam and Minister of the Navy. Adriaan studied law in Groningen and Kiel, when it was still a Danish city. (N.B. Holland was occupied by the French army between 1795 – 1813). With his Danish passport he traveled through Germany and England. In 1811, he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
