  1. 16. What characterizes persons with high and low GHG emissions? Lifestyles, well-being and values among Swedish households

    Författare :David Andersson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Greenhouse gas emissions; sustainable consumption; subjective-wellbeing; materialism; sustainable consumption;

    Sammanfattning : Global greenhouse gas (GHG) emissions need to be reduced to around a third of the current level before 2050 and approach zero at the end of the century if we are likely to reach the twodegree target. Sweden has sometimes been promoted as a model for the transition towards sustainable emission levels, with reductions of 20 percent between 1990 and 2012, but when embedded emissions from imported goods are accounted for (and exports are excluded) the development instead show an increase by at least 15 percent between 1993 and 2010.

  3. 17. Investigating Effects of Water Injection on SI Engines

    Författare :Jayesh Khatri; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knock Mitigation; Downsized SI engine; RON; Water Injection; Particulates; Relative Humidity;

    Sammanfattning : In recent years, there has been a major shift towards the partial or complete electrification of vehicles that have traditionally been powered by conventional internal combustion (IC) engines; almost all major automotive manufacturers have rightly stated that they will make such a shift. This has been motivated in large part by pressure from governments and policymakers to minimize vehicular emissions, especially those of the greenhouse gas CO2, in order to control climate change.

  4. 18. Exposure to crime as a consequence of poverty : five investigations about relative deprivation, poverty and exposure to crime

    Författare :Daniel Larsson; Björn Halleröd; Henrik Tham; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; poverty; exposure to crime; fear of crime; welfare problems; Sweden; Britain; Sociology; Sociologi;

    Sammanfattning : This thesis contains five studies that in different ways investigate poverty and the relation between poverty and exposure to crime. The basis of the thesis has been the question of how poverty is related to other welfare problems such as unemployment and health problems, focusing on exposure to crime and fear of crime. LÄS MER

  5. 19. Social participation, social capital and socioeconomic differences in health-related behaviours. An epidemiological study

    Författare :Martin Lindström; Socialmedicin och hälsopolitik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fat intake; health-related behaviour; intermittent smoking; multilevel analysis; neighbourhood; physical activity; psychosocial; smoking cessation; social capital; social participation; vegetable consumption; socioeconomic differences;

    Sammanfattning : Abstract OBJECTIVES: The aim of this study was to investigate whether psychosocial resources explain socioeconomic differences in smoking cessation and its maintenance. METHODS: A subpopulation of 11,837 individuals from the Malmö Diet and Cancer Study interviewed in 1992-94, age range 45-64 years, was investigated in this cross-sectional study. LÄS MER

  7. 20. Wood and fibre mechanics related to the thermomechanical pulping process

    Författare :Jan-Erik Berg; Per Engstrand; Per A. Gradin; Tomas Björkqvist; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic emission; Chips; Compression tests; Defibration; Disc refiners; Energy consumption; Fibre structure; Force sensors; Fracture; Impact strength; Mathematical analysis; Moisture content; Picea abies; Refining; Stiffness degradation; Strains; Temperature; Thermomechanical pulping; Velocity; Chemical engineering; Kemiteknik;

    Sammanfattning : The main objective of this thesis was to improve the understanding of some aspects on wood and fibre mechanics related to conditions in the thermomechanical pulping process. Another objective was to measure the power distribution between the rotating plates in a refiner. LÄS MER
