  1. 16. Novel Diagnostics and Computational Methods of Neutron Fluxes in Boiling Water Reactors

    Författare :John Loberg; Michael Österlund; Thomas Smed; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Void; BWR; neutron fluxes; channel bow; MCNP; 2D 3D; Physics; Fysik;

    Sammanfattning : The focus in this thesis is to improve knowledge of the BWR related uncertainties void, channel bow, and control rods. The presence of void determines the moderation of neutrons in BWRs. A high void fraction is less efficient in moderating neutrons than a low one. LÄS MER

  2. 17. Moisture Buffering in the Indoor Environment

    Författare :Kaisa Svennberg; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; furniture; textiles; moisture buffering; beds; indoor air; indoor environment; sorption isotherms; field measurements; definition scheme; Technological sciences;

    Sammanfattning : Moisture buffering in the indoor environment is the ability, through absorption and desorption, of surface materials to attenuate the moisture variations of the indoor air. Moisture buffering plays an important role in understanding the risks for biological growth in surface materials in the indoor environment, e.g. LÄS MER

  3. 18. Depression among Adolescents : Measurement and diagnosis, Environmental factors, and Genetics

    Författare :Catalina Torres Soler; Kent W. Nilsson; Cecilia Åslund; Sofia H Kanders; Åsa Westrin; Uppsala universitet; []
    Nyckelord :Adolescent; parent; depression; scale; genetics; Adolescente; padres; evaluación; scale; depression; genética; Child and Youth Psychiatry; Barn- och ungdomspsykiatri;

    Sammanfattning : Depression is a common disorder and a major cause of disability. The prevalence of depression in adolescents is 12-25%. The use of valid instruments in psychiatric assessment contributes to diagnostic validity and consistency. LÄS MER

  4. 19. Safeguards: Modelling of the Detection and Characterization of Nuclear Materials

    Författare :Andreas Enqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scintillation detectors; number distribution; nuclear safeguards; cross correlations; light pulse distribution; master equations; multiplicities; ¯ssile material;

    Sammanfattning : Nuclear safeguards is a collective term for the tools and methods needed to ensure nonproliferation and safety in connection to utilization of nuclear materials. It encompasses a variety of concepts from legislation to measurement equipment. LÄS MER

  5. 20. Bilder av Mittens rike. Kontinuitet och förändring i svenska resenärers Kinaskildringar 1749-1912 : Images of the Middle Kingdom. Continuity and Change in Swedish Travelers' Accounts of China, 1749-1912

    Författare :Kenneth Nyberg; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; images of China; national images; orientalism; imagology; travel accounts; ethnocentrism; Chinoiserie; Sino-Swedish relations; Sweden and China;

    Sammanfattning : The aim of this thesis is to describe and analyze the images of China in Swedish travelers’ published accounts – traditional travelogues as well as diaries, diplomatic reports, letters, and geographical handbooks – between 1749 and 1912. The main problem of the study is the question of continuity and change in these images, which are seen as the result of an encounter between preconceived notions and personal experience. LÄS MER
