  1. 11. Thermal response test : method development and evaluation

    Författare :Signhild Gehlin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : Since the first introduction of thermal response tests with mobile measurement devices in Sweden and USA in 1995, the method has developed and spread in North America and Europe. Thermal response tests have so far been used primarily for in situ determination of design data for BHE (borehole heat exchanger) systems, but also for evaluation of grout material, heat exchanger types and groundwater effects.

  3. 12. Thermal response tests : influence of convective flow in groundwater filled borehole heat exchanger

    Författare :Anna-Maria Gustafsson; Jeffrey D. Spitler; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

    Sammanfattning : The main objective of this doctorial thesis was to investigate how thermally induced movements in the groundwater (natural convective flow) may influence the heat transport in borehole and surrounding bedrock in a groundwater filled borehole heat exchanger system. The purpose was also to determine if thermal response tests could be used to detect the convective influence and the effect on evaluated heat transfer parameters, effective bedrock thermal conductivity and borehole thermal resistance.

  4. 13. Effects of Complement Opsonization of HIV on Dendritic Cells : and Implications for the Immune Response

    Författare :Rada Ellegård; Marie Larsson; Jorma Hinkula; Johan D Söderholm; William Paxton; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HIV; dendritic cells; complement; innate immune response; TLR signaling; T cell activation; NK cells; inflammation; antiviral response; immune evasion;

    Sammanfattning : Dendritic cells are key players during HIV pathogenesis, and shape both the immediate immune response at the site of infection as well as directing the adaptive immune response against the virus. HIV has developed a plethora of immune evasion mechanisms that hijack dendritic cell functions, suppressing their ability to mount an accurate immune response and exploiting them for efficient viral transfer to target T cells.

  5. 14. Linear response theory : from black hole thermalization to Weyl semimetals

    Författare :Jorge Laraña Aragón; Bo Sundborg; Edwin Langman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Linear response theory is an incredibly powerful calculation tool. We apply this framework in quantum field theory to a variety of models originated from distinct areas in theoretical physics and for different reasons. LÄS MER

  7. 15. Improving disaster response evaluations : Supporting advances in disaster risk management through the enhancement of response evaluation usefulness

    Författare :Ralf Josef Johanna Beerens; Avdelningen för Riskhantering och Samhällssäkerhet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; crisis; disaster; emergency; disaster risk management DRM ; preparedness; exercise; simulation; response; performance; evaluation; usefullness; design; The Netherlands;

    Sammanfattning : Future disasters or crises are difficult to predict and therefore hard to prepare for. However, while a specific event might not have happened, it can be simulated in an exercise. LÄS MER
