  1. 6. Resource and Environmental Impacts of Resource-Efficiency Measures Applied to Electronic Products

    Författare :Hampus André; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; scarce metals; life cycle assessment; resource-efficiency; electronic products; resource depletion; circular economy; metal resource use;

    Sammanfattning : Natural resources such as ecosystems, land, water and metals underpin the functioning of economies and human well-being, and are becoming increasingly scarce due to growth in population and affluence. Metals are increasingly demanded for their specific properties as modern technology develops. LÄS MER

  3. 7. Managing mountains, past and present conditions for traditional summer farming and Sami reindeer husbandry in northern Scandinavia

    Författare :Weronika Axelsson Linkowski; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Traditional land use and conditions for maintenance of biodiversity are often interlinked. When land use changes and ecosystems change as a result, there is a risk to loose both the traditional ecological knowledge and the biodiversity connected to this land use. LÄS MER

  4. 8. Optical sensors in drinking water production : Towards automated process control in relation to natural organic matter

    Författare :Claudia Cascone; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Access to safe and clean drinking water is a basic human right (A/RES/64/292). In Sweden, large drinking water treatment plants use mainly surface water as water source. The long-term trend of increasing natural organic matter (NOM) in boreal and north European surface waters negatively affects the overall performance of the treatment processes. LÄS MER

  5. 9. Networks of urban interaction - Growth and centrality in the complex geography of urban activity

    Författare :Alexander Hellervik; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; accessibility; power law; urban activity; centrality; urban growth; transport infrastructure; spatial interaction; complex networks; Zipf’s law;

    Sammanfattning : How cities and regions grow and decline depend on technological, social and economic factors. Understanding the interplay of these forces is central in research efforts aiming to improve urban and transport planning. LÄS MER

  7. 10. The role of rodents in the transmission of Echinococcus multilocularis and other tapeworms in a low endemic area

    Författare :Andrea Miller; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Echinococcus multilocularis is zoonotic tapeworm in the Taeniidae family with a two part lifecycle involving a canid definitive host and a rodent intermediate host. The work of this thesis followed the first identification E. multilocularis in Sweden in 2011 in a red fox (Vulpes vulpes). LÄS MER
