Marie Beatrice Schol-Schwarz
Marie Beatrice "Bea" Schol-Schwarz (12 July 1898 – 27 July 1969) was the Dutch phytopathologist who discovered the causal fungus of Dutch elm disease. She first studied pathogens afflicting peanuts and later the fungus '' Phialophora''. Biography Marie Beatrice Schwarz was born on 12 July 1898 in Batavia in the Dutch East Indies (present-day Jakarta, Indonesia). She studied at the Utrecht University in the Netherlands, where she was Johanna Westerdijk's first PhD student. During her studies in 1922, she discovered the causal fungus of Dutch elm disease. Schwarz spent most of her early professional life studying pathogens afflicting the groundnut ''Arachis hypogaea'' at the agricultural research station in Bogor. The elm tree ''Ulmus'' × ''hollandica'' 'Bea Schwarz' was named for her in recognition of her research into the cause of Dutch elm disease. Marrying in 1926, she retired from research to raise a family. When the East Indies were invaded by the Japanese army ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Japanese Occupation Of The Dutch East Indies
The Empire of Japan occupied the Dutch East Indies (now Indonesia) during World War II from March 1942 until after the end of the war in September 1945. It was one of the most crucial and important periods in modern Indonesian history. In May 1940, Germany occupied the Netherlands, and martial law was declared in the Dutch East Indies. Following the failure of negotiations between the Dutch authorities and the Japanese, Japanese assets in the archipelago were frozen. The Dutch declared war on Japan following the 7 December 1941 Attack on Pearl Harbor. The Japanese invasion of the Dutch East Indies began on 10 January 1942, and the Imperial Japanese Army overran the entire colony in less than three months. The Dutch surrendered on 8 March. Initially, most Indonesians welcomed the Japanese as liberators from their Dutch colonial masters. The sentiment changed, however, as between 4 and 10 million Indonesians were recruited as forced labourers ('' romusha'') on economic deve ...

Women In Forestry
A woman is an adult female human. Prior to adulthood, a female human is referred to as a girl (a female child or adolescent). The plural ''women'' is sometimes used in certain phrases such as "women's rights" to denote female humans regardless of age. Typically, women inherit a pair of X chromosomes, one from each parent, and are capable of pregnancy and giving birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, SRY-gene on either one of the respective sex chromosomes. Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. A fully developed woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. Women have significantly less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular than men. Through ...

People From Batavia, Dutch East Indies
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Ulmus 'Bea Schwarz'
The elm cultivar ''Ulmus minor'' 'Bea Schwarz' was cloned (as No. 62) at Wageningen in the Netherlands, by the elm disease committee, from a selection of ''Ulmus minor'' found in France in 1939. However, specimens of the tree grown in the UK and the United States are falsely treated as ''Ulmus × hollandica'' (after Fontaine ). Description The tree is considered of poor growth and shape if grafted on ''U.'' × ''hollandica'' rootstock. Nowadays it is sparsely grown on its own rootstock. Pests and diseases Not resistant to the second, more virulent, strain of Dutch elm disease, ''(O. novo-ulmi)'', but more resistant to Coral Spot fungus '' Nectria cinnabarina'' than its forebear 'Christine Buisman'. Cultivation Commercial production was discontinued in the Netherlands soon after its release in 1948.Went, J. C. (1954). ''Tijschr. Plantenziekten'' 60: 109-127, 1954. Nevertheless, its moderate resistance to Dutch elm disease saw it, or its selfed progeny, successfully used in late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
