  4. 3. 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.

  5. 4. Uptake and toxicity of brominated flame retardants and pesticides : Studies on littoral organisms and model communities

    Författare :Kerstin Gustafsson; Nils Kautsky; Kirsten Christoffersen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquatic ecotoxicology; ecological interactions; indirect effects; model community studies; toxicity; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : In this thesis, brackish and freshwater littoral model communities (microcosms) of varying size and complexity were used to study the effects of brominated flame retardants (BFRs) and pesticides. The brackish water microcosms consisted of natural water, sediment and associated organisms, while the larger freshwater microcosms also contained submersed macrophytes (Elodea canadensis). LÄS MER

  7. 5. Ships, clouds, and waves : understanding ecosystems in traditional industries

    Författare :Peter Gustafsson; Zsuzsanna Vincze; Sujith Nair; Llewellyn D.W. Thomas; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ecosystems; Orchestration; Emergence; Traditional Industries; Shipbuilding; Resource Dependence Theory; Collective Action Theory; Corporate Political Activity;

    Sammanfattning : This dissertation builds on a jointly phenomenological and theoretical approach to investigate how traditional industries face challenges related to ecosystem innovation. Phenomenologically, it investigates how innovation within the shipbuilding industry affects the activities performed by firms that have traditionally filled the role of suppliers to shipyards. LÄS MER
