Input: Consider Input: Passage: Lange was born in Warsaw into the patriotic Jewish family of Henryk Lange (18151884) and Zofia nee Eisenbaum (18321897). His father took part in the November Uprising against the Russian Partition of Poland. He was an admirerer of Romantic literature and its ideals. Antoni Lange enrolled at Warsaw University but around 1880 he was expelled for his patriotic activity by the Tsarist namiestnik Apuchtin who ruled the university at that time. He supported himself financially as a tutor but also published poetry under the pen-names Napierski and Antoni Wrzesien. He decided to study in Paris where he encountered new trends in literature, philosophy and art. In France he became familiar with the theories of Jean Martin Charcot, as well as Spiritualism, parapsychology, the philosophy of Arthur Schopenhauer and Friedrich Nietzsche, oriental religions, European and Eastern literature and modern literary criticism. He took part in the literary meetings of Stephane Mallarme.

Input: Consider Input: Passage: Han Groenewegen worked in the Hague as a freelance architect from 1920 to 1927. Before establishing his own firm, he used to work for the contractor R. Rutgers in the Hague. One of his few works in the Netherlands is the Church of the Holy Heart of Jesus in Schiedam. During the Great Depression, Groenewegen left the Netherlands to established his own new firm in the Dutch East Indies. Many other architects were left for the Indies during the period, e.g. Albert Aalbers. Groenewegen arrived in Medan (on the island of Sumatra) in 1927 to work on the plan for a hospital, the St. Elisabeth's Hospital (1929-1930). He was active in Medan from 1927 to 1942 to work for the Oostkust. Like Schoemaker for the city of Bandung, Gronewegen can be considered as representative of modernist Nieuwe Bouwen in Medan. Among Groenewegen's extensive portfolio in Medan are the expansion of Medan Cathedral (1928), Arnhem Insurance (now Museum Perjuangan TNI, 1930), the Roman Catholic Chinese church in Polonia (1934), Princess Beatrix School (now Immanuel Christian School, 1938), Medan swimming pool (1939), and Oranjeschool (1941). Unlike many of his colleagues however, Groenewegen remained in Indonesia following the independence of the country.

Input: Consider Input: Passage: The upper part of the watershed is constituted of Norra Jarvafaltet, an open-air area characterized by moraine ridges covered with forests separated by water meadows and tilled fields. While some 20 hectares of the surrounding area is used for pasture, the stream is bordered by deciduous plants such as Alder and Birch and Bulrush can be found in non-shadowed patches. Some 2,5 kilometres from its origin, the stream passes down in a culvert under a traffic route (Akallavagen) and the Barkarby Airport before merging with the stream Djupanbacken. This part of the catchment area contains a motocross track, a golf driving range, a closed dump, and receives stormwater from the E18 traffic route. Thereafter, the stream flows some 4km in the valley separating the suburbs Akalla-Hjulsta and Tensta-Rinkeby and where are several rural structures including an ecological farm (Hasta Gard), eight allotment-gardens, and some minor overgrown wetlands. East of the valley the river is crossed by a second traffic route (Kymlingelanken) before flowing 2,5km through an open grassland to reach a railway and the E4 traffic route, water from the latter treated in a local cleaning plant. The last 1.4km passes more allotment-gardens and the gardens of the Ulriksdal Palace before jumping into Edsviken through a low dam.
