  1. 11. Energy efficiency and the challenge of climate change - Studies of the Swedish building sector

    Författare :Jonas Nässén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology diffusion; input-output analysis; Energy efficiency; Swedish building sector; carbon dioxide;

    Sammanfattning : The interrelated environmental, social and economic challenges imposed by global climate change will make it one of the central political issues in the coming century. Use of fossil fuels is the largest source of anthropogenic CO2 emissions and hence the transformation of the energy system plays a central role in the mitigation of future climate change. LÄS MER

  3. 12. När man talar om knark : drogdebatt i svensk dagspress 1970-1999

    Författare :Daniel Törnqvist; Simon Lindgren; Sven-Åke Lindgren; Mats Hilte; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; drugs; debate; discourse analysis; media; press; newspapers; moral panics; Sweden; Sociology; Sociologi; sociologi; Sociology;

    Sammanfattning : This thesis presents a study of the debate on drugs in the Swedish press from 1970 to 1999. Applying a social constructionist and critical discourse perspective, it aims to map out and analyze the discourse on drugs in a large number of Swedish newspapers. The main focus is on debate articles and editorials. LÄS MER

  4. 13. Development and results of the Swedish road deflection tester

    Författare :Peter Andrén; Anders Eriksson; Anders Lenngren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : A project to construct a high-speed road deflection tester was initiated in the 1991. A mid-sized truck was used as a carrier for the first prototype. The results were promising and it was decided to build a full-size truck system. The new vehicle, based on a Scania R143 ML, was completed in 1997. LÄS MER

  5. 14. On the thermal inertia and time constant of single-family houses

    Författare :Johan Hedbrant; Björn Karlsson; Mats Söderström; Stig-Inge Gustafsson; Karin Adalberth; Linköpings universitet; []
    Nyckelord :Electric heating;

    Sammanfattning : Since the nineteen-seventies, electricity has become a common heating source in Swedish single-family houses. About one million smallhouses can use electricity for heating, about 600.000 have electricity as the only heating source. LÄS MER

  7. 15. Thermal insulation of the combustion chamber in a light duty diesel engine

    Författare :Joop Somhorst; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature swing; crevice effect.; porosity; heat transfer; surface roughness; efficiency; diesel engine; surface sealing; thermal barrier coating;

    Sammanfattning : Reduction of heat loss from the combustion chamber in an engine has great potential to decrease fuel consumption and CO2 emissions. Research on thermal barrier coatings (TBC) has been performed since the early eighties to address this potential. LÄS MER
