  1. 1. Vardagens landskap : lokala perspektiv på bronsålderns materiella kultur

    Författare :Peter Skoglund; Arkeologi; []
    Nyckelord :HUMANIORA; HUMANITIES; South Swedish higland; Fossil arable land; Rock-carving; Monument; Cultural heritage; Local perspective; Regional diversity; Praxis theory; Material culture; Landscape archaeology; Archaeology; Arkeologi;

    Sammanfattning : In the thesis the author discusses how materiel culture changed when it was incorporated into a local society. The discussion is based on graves, rock carvings and bronze items in south Scandinavia during the periods Late Neolithic and Bronze Age, 2350-500 BC. The thesis? starting point is a praxis perspective. LÄS MER

  3. 2. Decentralised energy systems based on biomass : a life cycle perspective on climate impact and energy balance

    Författare :Marie Kimming; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Replacing fossil fuels with renewable energy sources is recognised as an important measure to mitigate climate change. Residual biomass from agriculture and forestry and short-rotation coppice grown on unused land can be converted to heat, power and fuel without directly compromising production of edible crops.

  4. 3. Metabolic engineering for production of complex lipids in tobacco (Nicotiana benthamiana) leaves and rice (Oryza sativa) endosperm

    Författare :Selcuk Aslan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : World chemical and energy supplies for industry are today highly dependent on unsustainable fossil reserves. Vegetable lipids with similar chemical structures to fossil oil could be the ultimate renewable solution to replace fossil oil and provide environmentally friendly feedstocks and energy resources.

  5. 4. Genome editing of oilseed species by CRISPR/Cas9 for trait improvement

    Författare :Sjur Sandgrind; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The demand for vegetable oils for food and other applications is rapidly increasing due to a growing population and an urgent need to replace fossil oils. Furthermore, there are several challenges facing agricultural production, such as a shortage of arable land, climate change, and water pollution due to nutrient leaching from extensive use of fertilizers and tillage.

  7. 5. Development of Lepidium campestre into a new oil and catch crop

    Författare :Emelie Ivarson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : A growing world population and dwindling fossil oil reserves demand an increase in the world plant oil production. The possibility to increase the area of cultivated land is limited due to the shortage of arable land. Also, the possibility for increasing the oil content in the limited number of cultivated oil crops is restricted. LÄS MER
