  1. 1. Infrared Laser-Induced Grating Techniques for Diagnostics in Reactive Flows

    Författare :Dina Hot; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser diagnostics; infrared; laser-induced grating spectroscopy; degenerate four-wave mixing; flames; temperature; concentration; Fysicumarkivet A:2020:Hot;

    Sammanfattning : AbstractThe work presented in this thesis is mainly focused on the development andapplication of infrared laser-induced grating techniques in order to measure the gasphase temperature and species concentrations in reactive flows. The two techniquesused for this purpose are laser-induced grating spectroscopy (LIGS) and degeneratefour-wave mixing (DFWM). LÄS MER

  3. 2. Från den västerbottniska frostmyren till den socialpolitiska hetluften: : Astrid Väring - konservativ författare i Folkhemmets Sverige

    Författare :Karin Edlund; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; The Frost; Norrland literary tradition; postcolonialism; popular literature; roman à thèse; mental health care; Literature; litteraturvetenskap;

    Sammanfattning : The dissertation takes as its starting-point the dichotomies between origin and modernity, periphery and centre. This is particularly the case in Astrid Väring’s novels Frosten (1926) and Vintermyren (1927), in which the author pays tribute to the homestead and the rural community in contrast to the industrial community, whilst her novels also express an ambivalent attitude towards modernity.

  4. 3. Creep, deformation and moisture redistribution during air convective wood drying and conditioning : air convective wood drying and conditioning

    Författare :Tom Morén; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : Air convective wood drying is associated with a considerable risk for damage to the timber, especially checking and warping. This thesis contains an analysis of creep and deformation during wood drying related to stress development and susceptibility of checking. Also heat and mass transfer problems in the wood drying process are considered. LÄS MER

  5. 4. Inhibited electrical discharges in air

    Författare :Anders Larsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; elektronik; Electronics;

    Sammanfattning : Modem society requires a stable electricity supply, the reliability of which is partlydetermined by the dielectric strength of the outdoor high-voltage insulation systems.This thesis concentrates upon one particular discharge phenomenon that occurs whensuch a system is subjected to rain, namely the inhibited discharge.
