    Sammanfattning : The significant environmental impact of the current fossil fuel-based industry is a major concern for society. Consequently, various initiatives are being undertaken to establish a more sustainable industrial model. LÄS MER

  3. 2. Growth and decline in rural Sweden : geographical distribution of employment and population 1960–2010

    Författare :Martin Hedlund; Linda Lundmark; Emma Lundholm; Olof Stjernström; Kjell Overvåg; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; rural restructuring; rural heterogeneity; manufacturing decline; agricultural decline; urbanization; rural typology; life-course perspective; cluster analysis; Sweden; Social and Economic Geography; kulturgeografi;

    Sammanfattning : This thesis investigates the combination of changes in the population and employment into sectors in rural Sweden for the period 1960-2010. The aim is to describe and analyze the demographic changes together with the labour market changes, and to account for the spatial outcome of these changes by considering the heterogeneity of rural areas.

    Sammanfattning : This dissertation is a study of how local municipalities handle local industrial crises. More specifically the aim is to investigate the change in ideas and concepts that lead to a change in industrial policy during the industrial crisis in the 1970’s and 1980’s in Söderhamn. LÄS MER

  5. 4. Biological Pretreatment and Dry Digestion Processes for Biogas Production

    Författare :Regina Patinvoh; Thierry Ribeiro; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid wastes; Dry anaerobic digestion; Textile bioreactor; Plug flow bioreactor; Digestate; Process stability; Pretreatment; Co-digestion; Mesophilic; Resource Recovery; Resursåtervinning;

    Sammanfattning : Biogas technology has been used quite extensively to generate renewable energy from organic wastes while also recycling nutrients in the wastes and reducing harmful emissions. However, the challenges of low biogas yield from recalcitrant and inhibitory solid wastes together with high construction and operation costs of bioreactors have impeded optimal performance through this process.
