  3. 22. Towards sustainable energy consumption : Electricity demand flexibility and household fuel choice

    Författare :Aemiro Melkamu Daniel; Lars Persson; Runar Brännlund; Rauli Svento; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Choice experiment; demand flexibility; electricity contract; fuel choice; fuel stacking; household heterogeneity; load control; pro-environmental framing; willingness-to-accept;

    Sammanfattning : Paper [I] investigates household heterogeneity in valuing electricity contract attributes that include various load controls and information sharing to induce demand flexibility. Using a stated preference choice experiment conducted with Swedish households, this paper shows that, although a large proportion of households ask for substantial compensation, some households are willing to share their electricity consumption information and require relatively lower compensation to allow load controls.

  4. 23. Pyrolysis of biomass in fluidized-beds: in-situ formation of products and their applications for ironmaking

    Författare :Pelle Mellin; Weihong Yang; Blasiak Wlodzimierz; Gerrit Brem; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pyrolysis; Fluidized bed; CFD; Blast furnace; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The iron and steel industry emitted 8 % of all CO2 emissions in Sweden, 2011. Investigating alternative energy carriers is the purpose of this thesis. By pyrolyzing biomass, an energetic solid, gaseous and liquid (bio oil) fraction is obtained. LÄS MER

  5. 24. Diesel exhaust and wood smoke : mechanisms, inflammation and intervention

    Författare :Ala Muala; Thomas Sandström; Mark W Frampton; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Air pollution; deposition; bronchoscopy; Immunohistochemstry; filter; NO bioavailability; lungmedicin; Lung Medicine;

    Sammanfattning : Background Particulate matter (PM) air pollution is associated with increased respiratory and cardiovascular morbidity and mortality. Diesel engine exhaust (DE) and wood combustion are major contributors to ambient air pollution and adverse health effects. LÄS MER

  7. 25. A Study on the Population and Chemical Development of Non-Metallic Inclusions in the Tool-Steel Making Process

    Författare :Nagendra Tripathi; KTH; []
    Nyckelord :Metallurgy; Inclusions; Industrial; Technology;

    Sammanfattning : The present work was to study the population and chemicalcharacterization of the inclusions at different steps of thetool steel making process based on industrial trialexperiments. The inclusion populations were found to increasewith ladle age (number of heats ladle being used) beforealuminium deoxidation and before casting. LÄS MER
