  1. 16. Essays on Environmental and Energy Economics

    Författare :Haishan Yu; Chuan-Zhong Li; Bertil Holmlund; Tomas Sjögren; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Carbon market; Difference-in-differences; Electricity market; Time series model; Carbon emissions; Global warming; Ocean acidification; Threshold effect; Lump-sum transfers; Equity and efficiency; Economics; Nationalekonomi;

    Sammanfattning : Essay I: In January, 2005, the EU launched the first international emissions trading system (EU ETS), aimed at reducing carbon emissions in a cost-effective way by means of a market-based instrument. In this paper, we use the treatment/control, before/after design of the natural experiment approach to investigate the treatment effect of the EU ETS on the profitability of a sample of Swedish energy firms in 2005 and 2006.

  3. 17. Experimental studies of turbulent boundary layer separation and control

    Författare :Kristian Angele; KTH; []
    Nyckelord :turbulence; boundary layer; separition; adverse pressure graddient;

    Sammanfattning : The object ofthe present work is to experimentally study thecase ofa turbulent boundary layer subjected to an AdversePressure Gradient (APG) with separation and reattachment. Thisconstitutes a good test case for advanced turbulence modeling. LÄS MER

  4. 18. Characterization and Separation of Suspension Cells by Isoacoustic Focusing

    Författare :Mahdi Rezayati Charan; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Enabling techniques for separating target cells, such as subgroups of white blood cells and cancercells from blood and other body fluids, are necessary for lab work facilitation, inline integration withhigh-end bioanalytical instrumentation, and for point-of-care or home testing. The work of this thesisaddresses this need by further studying an equilibrium-based ultrasonic wave-based technology calledisoacoustic focusing to characterize and gain access to cells. LÄS MER

  5. 19. Reducing household waste : A social practice perspective on Swedish household waste prevention

    Författare :Mimmi Bissmont; Kerstin Sandell; Hans Bertil Wittgren; Malmö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis studies household waste prevention from a social scienceperspective. Swedish waste management is efficient in handling wastebut has not succeeded in reducing its quantities, even though theissue of waste prevention is being raised at both international andnational levels.

  7. 20. Assessing Carbon Dioxide Removal methods amid uncertainty : soil carbon sequestration, biochar and harvested wood products as methods for climate change mitigation

    Författare :Alexander Olsson; Stefan Grönkvist; Mathias Fridahl; Anders Hansson; Lowe Börjeson; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Dioxide Removal CDR ; Negative Emissions Technologies NETs ; Soil Organic Carbon; Biochar; Harvested Wood Products HWP ; Socio-technical systems; Strategic Niche Management SNM ; Chemical Engineering; Kemiteknik;

    Sammanfattning : Measures to sequester carbon dioxide (CO2) away from the atmosphere have become increasingly important in the discussion of which methods humans can employ to limit global warming. These measures, which are broad and varied, fall under the umbrella of Carbon Dioxide Removal (CDR) methods. LÄS MER
