  1. 1. Diet and common neurological disorders: cohort studies on dementia, Parkinson’s disease, and stroke

    Författare :Erika Olsson; Susanna C. Larsson; Liisa Byberg; Lena Kilander; Emily Sonestedt; Uppsala universitet; []
    Nyckelord :diet; dietary pattern; Healthy Diet Indicator; Mediterranean diet; low carbohydrate; vitamin D; 25-hydroxyvitamin D; Mendelian randomization; milk; fermented milk; epidemiology; cohort study; Alzheimer’s disease; dementia; cognitive impairment; Parkinson’s disease; stroke; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Risk factors for dementia, Parkinson’s disease, and stroke have been widely studied but there are still research gaps concerning the role of diet for the development of these diseases. The overall aim of this thesis was to investigate whether various aspects of diet are associated with common disorders and diseases in the brain. LÄS MER

  3. 2. Analytical photoacoustic model of laser-induced ultrasound in a planar layered structure

    Författare :Erika Svanström; Erik Olsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : A way of describing photoacoustic measurement techniques is listening to light. Another way is as sensor techniques for characterisation of materials by means of light and sound interacting with the material under investigation. LÄS MER

  4. 3. Further Investigations of Convergence Results for Homogenization Problems with Various Combinations of Scales

    Författare :Tatiana Danielsson; Anders Holmbom; Liselott Flodén; Marianne Olsson Lindberg; Erika Schagatay; Peter Wall; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is based on six papers. We study the homogenization of selected parabolic problems with one or more microscopic scales in space and time, respectively. LÄS MER

  5. 4. Homogenization Results for Parabolic and Hyperbolic-Parabolic Problems and Further Results on Homogenization in Perforated Domains

    Författare :Tatiana Lobkova; Anders Holmbom; Liselott Flodén; Marianne Olsson Lindberg; Erika Schagatay; Peter Wall; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is based on four papers. The main focus is on homogenization of selected parabolic problems with time oscillations, and hyperbolic-parabolic problems without time oscillations. The approaches are prepared by means of certain methods, such as two-scale convergence, multiscale convergence and evolution multiscale convergence. LÄS MER
