  1. 11. Learning science by digital technology : Students’ understanding of computer animated learning material

    Författare :Göran Karlsson; Berner Lindström; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Digital learning material is associated with grand expectations among educational policy makers. Several attempts to introduce this new technology with the purpose of enhancing learning have been made in recent years. The schooling system has, however, been rather hesitant and not so ready to adopt this kind of teaching aid. LÄS MER

  3. 12. Life Cycle Thinking in Environmentally Preferable Procurement

    Författare :Elisabeth Hochschorner; Göran Finnveden; Anna Björklund; Ann-Marie Tillman; KTH; []
    Nyckelord :Life Cycle Thinking; Life Cycle Assessment; Environmental Procurement; Life Cycle Costing; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Products generate environmental impacts during their life cycle by consuming raw materials and energy, releasing emissions and producing waste. A procurement organisation can be a considerable driving force for more environmentally friendly products e.g. by requiring that products meet certain environmental criteria. LÄS MER

  4. 13. Learning Human Gait

    Författare :Parinaz Kasebzadeh; Fredrik Gustafsson; Gustaf Hendeby; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Pedestrian navigation in body-worn devices is usually based on global navigation satellite systems (GNSS), which is a sufficient solution in most outdoor applications. Pedestrian navigation indoors is much more challenging. Further, GNSS does not provide any specific information about the gait style or how the device is carried. LÄS MER

    Sammanfattning : Carbon dioxide (CO2) emissions from human activities are driving climate change, but the pending crisis could be mitigated by a circular carbon economy where released CO2 is recycled into commodity chemicals. Autotrophic microbes can make a contribution by producing chemicals, such as biofuels, from CO2 and renewable energy. LÄS MER

  7. 15. Northern Permafrost Region Soil Carbon Dynamics since the Last Glacial Maximum : a terrestrial component in the glacial to interglacial carbon cycle

    Författare :Amelie Lindgren; Gustaf Hugelius; Peter Kuhry; Fortunat Joos; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Soil organic carbon; Permafrost; Peat; Loess; Vegetation; Biome reconstruction; Last Glacial Maximum; Deglaciation; Glacial-interglacial cycle; Carbon cycle; Physical Geography; naturgeografi;

    Sammanfattning : At the Last Glacial Maximum (LGM), after ~100,000 years of relatively cold temperatures and progressively lower atmospheric carbon dioxide (CO2) concentrations, CO2 levels reached ~180 ppm, which is less than half of what we see today in a much warmer world (~400 ppm). Although much of this increase since the LGM is due to human-induced emissions, about 100 ppm of this increase can be attributed to natural variations seen over glacial to interglacial cycles. LÄS MER
