Victor Jacob Koningsberger
Victor Jacob Koningsberger (10 February 1895 – 28 February 1966) was a Dutch botanist and academic. Born in the Dutch East Indies, he completed his studies in Rotterdam and Utrecht, defending his doctoral dissertation – an exploration of the influence of light on plant growth – in 1922. He subsequently spent a decade in the Indies administering centres for sugar cane experimentation before returning to the Netherlands to replace his teacher Frits Went as Professor of Botany at Utrecht University. In this capacity, he continued to explore tropism. He served as the rector of Utrecht University between 1952 and 1953. Koningsberger was Chairman of the Royal Tropical Institute from 1951 through 1965, as well as a member of the Royal Netherlands Academy of Arts and Sciences from 1948 until his death. For his contributions, he was inducted into the Orders of the Netherlands Lion and the Orange-Nassau. He has been commemorated with a series of lectures, as well as a ...

Netherlands In World War I
The Netherlands remained neutral during World War I, a stance that arose partly from a strict policy of neutrality in international affairs that started in 1830, with the secession of Belgium from the Netherlands. Dutch neutrality was not guaranteed by the major powers in Europe and was not part of the Dutch constitution. The country's neutrality was based on the belief that its strategic position between the German Empire, German-occupied Belgium, and the British guaranteed its safety. The Royal Netherlands Army was mobilized throughout the conflict, as belligerents regularly attempted to intimidate the Netherlands and to place demands on it. In addition to providing a credible deterrence, the army had to house refugees, guard internment camps for captured soldiers, and prevent smuggling. The government also restricted the free movement of people, monitored spies, and took other wartime measures. Background Before the First World War, the Netherlands hosted two major inte ...

Kamp Sint-Michielsgestel
Kamp Sint-Michielsgestel was an ilag that was set up by the German occupiers during World War II in the Ruwenberg boarding school and the Beekvliet minor seminary in Sint-Michielsgestel. History Notable hostages On 4 May 1942, Kamp Sint-Michielsgestel, located in the Beekvliet minor seminary in Sint-Michielsgestel, was opened. The first inhabitants were 460 prominent Dutch individuals arrested that day, including politicians, mayors, professors, clergy, lawyers, writers, and musicians. Until the end of 1944, hundreds of notable Dutch citizens were held hostage. The Nazis believed that by holding these people as hostages, they could control the Dutch resistance and stated that they would be executed in the event of unrest in the country. Indische hostages In May 1942, the Indische hostages were also transferred to Kamp Sint-Michielsgestel. Most of the Indische hostages were Dutch people on leave from the Dutch East Indies and were taken hostage in July 1940 as retaliation f ...

Rudolph Cleveringa
Rudolph Pabus Cleveringa (2 April 1894, Appingedam, Netherlands – 15 December 1980, Oegstgeest, Netherlands) was a professor of law at Leiden University. He is known for his speech of 26 November 1940, in which he protested against the dismissal of Jewish colleagues ordered by the German occupation authorities. Youth and education Cleveringa was born in Appingedam. When he was four, his family moved to Heerenveen. Cleveringa received his secondary education in Leeuwarden, and studied with van Kleffens at Leiden University. In June 1917 he completed his doctoral studies and in 1919 he obtained his PhD cum laude. His thesis, emphasizing legal history aspects, was titled ''De zakelijke werking van de ontbindende voorwaarde'' ("The ''in rem'' effect of the escape clause"). Work and resistance After a brief stint at the court of Alkmaar in 1927 he was appointed Professor of Commercial Law and Civil Law at Leiden University. There, on November 26, 1940, in his capacity as Dean of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Netherlands In World War II
Despite Dutch neutrality, Nazi Germany invaded the Netherlands on 10 May 1940 as part of Fall Gelb (Case Yellow). On 15 May 1940, one day after the bombing of Rotterdam, the Dutch forces surrendered. The Dutch government and the royal family relocated to London. Princess Juliana and her children sought refuge in Ottawa, Canada until after the war. The invaders placed the Netherlands under German occupation, which lasted in some areas until the German surrender in May 1945. Active resistance, at first carried out by a minority, grew in the course of the occupation. The occupiers deported the majority of the country's Jews to Nazi concentration camps. Due to the high variation in the survival rate of Jewish inhabitants among local regions in the Netherlands, scholars have questioned the validity of a single explanation at the national level. In part due to the well-organized population registers, about 70% of the country's Jewish population were killed in the course of Worl ...

Auxin
Auxins (plural of auxin ) are a class of plant hormones (or plant-growth regulators) with some morphogen-like characteristics. Auxins play a cardinal role in coordination of many growth and behavioral processes in plant life cycles and are essential for plant body development. The Dutch biologist Frits Warmolt Went first described auxins and their role in plant growth in the 1920s. Kenneth V. Thimann became the first to isolate one of these phytohormones and to determine its chemical structure as indole-3-acetic acid (IAA). Went and Thimann co-authored a book on plant hormones, ''Phytohormones'', in 1937. Overview Auxins were the first of the major plant hormones to be discovered. They derive their name from the Greek word αυξειν (''auxein'' – "to grow/increase"). Auxin is present in all parts of a plant, although in very different concentrations. The concentration in each position is crucial developmental information, so it is subject to tight regulation through both ...

Sugar Cane
Sugarcane or sugar cane is a species of (often hybrid) tall, perennial grass (in the genus '' Saccharum'', tribe Andropogoneae) that is used for sugar production. The plants are 2–6 m (6–20 ft) tall with stout, jointed, fibrous stalks that are rich in sucrose, which accumulates in the stalk internodes. Sugarcanes belong to the grass family, Poaceae, an economically important flowering plant family that includes maize, wheat, rice, and sorghum, and many forage crops. It is native to the warm temperate and tropical regions of India, Southeast Asia, and New Guinea. The plant is also grown for biofuel production, especially in Brazil, as the canes can be used directly to produce ethyl alcohol (ethanol). Grown in tropical and subtropical regions, sugarcane is the world's largest crop by production quantity, totaling 1.9 billion tonnes in 2020, with Brazil accounting for 40% of the world total. Sugarcane accounts for 79% of sugar produced globally (most of the rest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gravitropism
Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant in response to gravity pulling on it. It also occurs in fungi. Gravity can be either "artificial gravity" or natural gravity. It is a general feature of all higher and many lower plants as well as other organisms. Charles Darwin was one of the first to scientifically document that roots show ''positive gravitropism'' and stems show ''negative gravitropism''. That is, roots grow in the direction of gravitational pull (i.e., downward) and stems grow in the opposite direction (i.e., upwards). This behavior can be easily demonstrated with any potted plant. When laid onto its side, the growing parts of the stem begin to display negative gravitropism, growing (biologists say, turning; see tropism) upwards. Herbaceous (non-woody) stems are capable of a degree of actual bending, but most of the redirected movement occurs as a consequence of root or stem growth outside. The mechanism is ...
