  1. 16. Environmental preferences among steel stakeholders

    Författare :Stina Alriksson; Marianne Henningsson; Carl-Erik Grip; Anders Roos; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conjoint analysis; environmental communication; focus group; light weighting; PLS; preferences; Q-methodology; risk perception; steel; stakeholders; Miljövetenskap; Environmental Science;

    Sammanfattning : Emissions of carbon dioxide, dioxins, nitrogen oxides and particulate matter as well as use of non-renewable resources and energy are some important sustainability challenges for the Swedish steel industry. Much effort has been made, mainly by technical solutions, which to a high degree have decreased the emissions during the last 30 years. LÄS MER

  3. 17. Wind energy siting: Challenges in applying spatial multi-criteria for planning support

    Författare :Deepa Manolan Kandy; Mörtberg Mörtberg; Gesa Geissler; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Increasing emissions of greenhouse gases and subsequent impacts on environment and societypronounces the need for transition into renewable energy globally. Sweden aims to achieve 100 %renewable electricity by year 2040 with a major share expected to come from wind power. LÄS MER

  4. 18. Three essays on Swedish energy and climate policy options : dynamic CGE-models with heterogeneous forests and an econometric model of fuel substitution in district heating plants

    Författare :Örjan Furtenback; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis contains three papers. Paper I: Demand for waste as fuel in the Swedish district heating sector: a production function approach. LÄS MER

  5. 19. Life cycle assessment of bridges, model development and case studies

    Författare :Guangli Du; Raid Karoumi; Håkan Sundquist; Gervásio Helena dos Santos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable construction; Life cycle assessment; LCA; Global warming; Bridge LCA; CO2 emissions; Cumulative energy demand; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : In recent decades, the environmental issues from the construction sector have attracted increasing attention from both the public and authorities. Notably, the bridge construction is responsible for considerable amount of energy and raw material consumptions. LÄS MER

  7. 20. Secondary absorbed dose distributions and radiation quality in light ion therapy

    Författare :Martha Hultqvist; Irena Gudowska; Tatsuhiko Sato; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; secondary doses; light ion therapy; radiation quality; Monte Carlo simulation; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : Radiotherapy with light ions offers the possibility of achieving a dose distribution which is highly conformed to the target volume while sparing normal tissues. For ions heavier than protons, an additional advantage is the increased Relative Biological Effectiveness (RBE) as compared to conventional photon and electron beams. LÄS MER
