Hendrik De Wit
Hendrik (Henk) Cornelis Dirk de Wit (24 October 1909 – 16 March 1999) was a Dutch systematic botanist who contributed significantly to the knowledge of the Aroid genera '' Cryptocoryne'' and '' Lagenandra''. He grew up in the Waterland, a marshy area in the Northwest Netherlands, and had a lifelong interest in aquatic plants. Career De Wit studied biology at the University of Amsterdam from 1931-1937. In 1937 he left for Pretoria, South Africa, where he worked as an agricultural research officer with the Department of Agriculture. In 1941 he obtained his Ph.D. with a thesis on the genus ''Setaria'' from the grass family ( Poaceae). In the same year, he moved to the Dutch East Indies (nowadays Indonesia). During World War II de Wit worked in the 's Lands Plantentuin te Buitenzorg. After his return to The Netherlands in 1946 he worked for the Flora Malesiana Foundation. De Wit was a gifted teacher and on 20 September 1953 he became a lecturer at Leiden University where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purmerend
Purmerend () is a city and municipality in the west of the Netherlands, in the province of North Holland and in the region of West Friesland. The city is surrounded by polders, such as the Purmer, Beemster and the Wormer. The city became the trade center of the region but the population grew relatively slowly. Only after 1960 did the population start to grow from around 10,000 to around 80,000 by the 2010s. From the 1960s onwards, Purmerend has seen major expansion and continues to do so. This expansion has turned Purmerend into a commuter town; many inhabitants of Purmerend (14,200 in 2011) work, go to school or spend their leisure time in Amsterdam. Purmerend is part of the Randstad, one of the largest conurbations in Europe. The municipality of Beemster merged into the municipality of Purmerend on 1 January 2022. The extended municipality has a population of about 92,000 inhabitants. History Early history Purmerend was created out of the small fishing village Purmer, wh ...

Research Assistant
A research assistant (RA) is a researcher employed, often on a temporary contract, by a university, a research institute or a privately held organization, for the purpose of assisting in academic or private research. Research assistants are not independent and are responsible to a supervisor or principal investigator and usually are not directly responsible for the outcome of the research. However, in some countries, research assistants can be the main contributor to the outcome of the research. Research assistants are often educated to degree level and might be enrolled in a postgraduate degree program and simultaneously teach, for example, if enrolled in a PhD programme they are known as Doctoral Research Assistants. Undergraduate and post-doctoral level Although a research assistant is normally appointed at graduate level, undergraduates are also sometimes appointed to support research. In Economics and Business, for instance, numerous research assistantship opportunities are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance ( shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedr ...

Plant Taxonomy
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally not having any close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy. Background Classification systems serve the purpose of grouping organisms by characteristics common to each group. Plants are distinguished from animals by various tra ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dutch East Indies
The Dutch East Indies, also known as the Netherlands East Indies ( nl, Nederlands(ch)-Indië; ), was a Dutch colony consisting of what is now Indonesia. It was formed from the nationalised trading posts of the Dutch East India Company, which came under the administration of the Dutch government in 1800. During the 19th century, the Dutch possessions and hegemony expanded, reaching the greatest territorial extent in the early 20th century. The Dutch East Indies was one of the most valuable colonies under European rule, and contributed to Dutch global prominence in spice and cash crop trade in the 19th to early 20th centuries. The colonial social order was based on rigid racial and social structures with a Dutch elite living separate from but linked to their native subjects. The term ''Indonesia'' came into use for the geographical location after 1880. In the early 20th century, local intellectuals began developing the concept of Indonesia as a nation state, and set the st ...
