  1. 1. Biomarkers of fish consumption and risk of stroke or myocardial infarction

    Författare :Maria Wennberg; Jan-Håkan Jansson; Ingvar Bergdahl; Maria Albin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fish consumption; omega-3 fatty acids; eicosapentaenoic acid; docosahexaenoic acid; methylmercury; selenium; lead; cadmium; stroke; myocardial infarction; erythrocytes; food frequency questionnaire; Environmental medicine; Miljömedicin; Epidemiology; epidemiologi; hälso- och sjukvårdsforskning; health services research; medicin; Medicine; Environmental Science; miljövetenskap; näringslära; Nutrition;

    Sammanfattning : The effect of fish consumption on the risk of cardiovascular disease has been extensively studied. Omega-3 fatty acids present in fish, namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been found to have beneficial effects through several mechanisms. In addition, selenium, an antioxidant, may be protective. LÄS MER

  3. 2. Electrostatically Driven Structure Formation in Clay Dispersions

    Författare :Maria Jansson; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lera; Montmorillonit; Laponite®; Taktoid; Anisotropi; Överladdning; Interkalering; Grov korninga modeller; MD simuleringar; MC simuleringar; SAXS; Svälltryck; zeta-potential; Clay; Montmorillonite; Laponite®; Nanoplatelets; Tactoid; Anisotropy; Overcharging; Intercalation; Coarse-grained modeling; MD simulations; MC simulations; SAXS; Swelling pressure; zeta-potential;

    Sammanfattning : Clay minerals consist of clay platelets, which are anisotropic in both size and charge, and these can form a lamellar structure depending on the size, making it a seemingly perfect model system for an electrical double layer. The situation is however, from a structural point, slightly less ideal. LÄS MER

  4. 3. Evaluation of the Tactoid Formation in Clay Systems

    Författare :Maria Jansson; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lera; Montmorillonit; Nano-plattor; Taktoider; Anisotropi; Grov korninga modeller; MD simuleringar; MC simuleringar; SAXS; Svälltryck; Clay; Montmorillonite; Nanoplatelets; Tactoid; Anisotropy; Coarse-grained models; MD simulations; MC simulations; SAXS; Swelling pressure;

    Sammanfattning : Clay minerals consist of anisotropic nanoplatelets where the majority of the clay minerals are highly charged, and thus, swell in aqueous solution. The structure and swelling depend on the type of clay mineral, and also on the ionic composition, and temperature. LÄS MER

  5. 4. Homecare and technology : old dreams - new means?

    Författare :Maria Jansson; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Informatik; Informatics;

    Sammanfattning : To meet the demands and to maintain an acceptable level of services in health and homecare, implementation and use of ICT as support for caring work, are increasing. The assumption is that technology will give rise to a large number of improvements, such as effectiveness and ability to follow up and evaluate the performance of the services provided. LÄS MER

  7. 5. Participation, knowledges and experiences : design of IT-systems in e-home health care

    Författare :Maria Jansson; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Informatik; Informatics;

    Sammanfattning : People working in the home health care sector are seldom consulted when development and implementation of ICT is involved and which effects their work practices. This is surprising given the assumptions of participatory design principles that have in¬fluenced Scandinavian re¬search and design work. LÄS MER
