  1. 1. Offshore Marine Substation for Grid-Connection of Wave Power Farms : An Experimental Approach

    Författare :Rickard Ekström; Karin Thomas; Frans Dijkhuizen; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; Offshore Marine Substation; Grid-Connection; Electrical Systems; Voltage-Source Inverter; On-load Tap Change; Cascaded H-bridge Multilevel Inverter; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Wave power is a renewable energy source with great potential, which is why there are more than a hundred ongoing wave power projects around the world. At the Division of Electricity, Uppsala University, a point-absorber type wave energy converter (WEC) has been proposed and developed. LÄS MER

  3. 2. Single Phase Convective Heat Transfer with Nanofluids : An Experimental Approach

    Författare :Ehsan Bitaraf Hgahighi; Björn E. Palm; Elena V. Timofeeva; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofluid; convective heat transfer; thermal conductivity; viscosity; heat transfer coefficient; performance; pumping power; Reynolds number; shelf stability;

    Sammanfattning : Nanofluids (NFs) are engineered colloids of nanoparticles (NPs) dispersed homogenously within base fluids (BFs). Due to the presence of NPs, the thermophysical and transport properties of BFs are subject to change. LÄS MER

  4. 3. What contributes to human body burdens of phthalate esters? : An experimental approach

    Författare :Georgios Giovanoulis; Cynthia A. de Wit; Jörgen Magnér; Brice Appenzeller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phthalates; Alternative plasticizers; DINCH; In vivo screening; Urine; Nails; Air; Dust; Hand wipes; Duplicate diet; Predictors of exposure; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Phthalate esters (PEs) and alternative plasticizers used as additives in numerous consumer products are continuously released into the environment leading to subsequent human exposure. The ubiquitous presence and potential adverse health effects (e.g. LÄS MER

  5. 4. What contributes to human body burdens of halogenated flame retardants? : An experimental approach

    Författare :Joo Hui Tay; Cynthia de Wit; Ulla Sellström; Jochen Mueller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; halogenated flame retardants; air; dust; hand wipes; duplicate diet; serum; human exposure; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Flame retardants (FRs) are chemicals added to a broad range of consumer products such as textiles, electrical and electronic equipment, furniture and building material to meet flammability requirements. Most of these chemicals are additives that can continuously leach out from the applied products during usage. LÄS MER

  7. 5. Experimental Governance : Capacity and legitimacy in local governments

    Författare :Erica Eneqvist; Andrew Karvonen; Hans Westlund; Kersti Karltorp; Annica Kronsell; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Experimental governance; legitimacy; municialities; democracy; organisational capacity; capacity-building; local government; public sector innovation; Urbana och regionala studier; Urban and Regional Studies;

    Sammanfattning : Contemporary planning and governance of cities involves practices of experiments and trials in urban experiments, collaborative platforms, and urban development projects with high ambitions for sustainability and innovative solutions. These practices of experimental governance can be seen as new policy instruments that include actors from all sectors of society in collective problem-solving. LÄS MER
