  1. 21. Frame Analysis in Environmental Conflicts : The case of ethanol production in Brazil

    Författare :Ester Galli; Ronald Wennersten; Tom Dwyer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brazil; biodiversity; biofuel; CO2 emissions; environmental conflict; ethanol; frame; frame analysis; land use change; sugarcane; sugarcane cutters; sustainable energy;

    Sammanfattning : Governments and policy-makers are currently dealing with some key issues as energy security in countries dependent on oil imports; global economic development, including increased food production; and controlling global climate change and greenhouse gas emissions. The perception that biofuel could solve these challenges simultaneously has led to the implementation of policy and regulatory mechanisms on the mandatory use of biofuels, resulting in a sharp increase in biofuel production and consumption.

  3. 22. Forecasting of Icing Related Wind Energy Production Losses : Probabilistic and Machine Learning Approaches

    Författare :Jennie Molinder; Anna Sjöblom; Heiner Körnich; Hans Bergström; Erik Nilsson; Sue Ellen Haupt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wind energy; Icing on wind turbines; Machine learning; Probabilistic forecasting; Meteorologi; Meteorology;

    Sammanfattning : Icing on wind turbine blades causes significant production losses for wind energy in cold climate. Next-day forecasts of these production losses are crucial for the power balance in the electrical grid and for the trading process, but they are uncertain due to lack of understanding of, and simplifications, in the modelling chain.

  4. 23. Human Fetal Hemoglobin : Biochemical Characterization and Recombinant Production

    Författare :Khuanpiroon Ratanasopa; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Blood substitutes; HBOCs; HbF; recombinant hemoglobin; pseudoperoxidase; ITC; haptoglobin;

    Sammanfattning : Blood transfusion is a common medical procedure when oxygen supply in the body is impaired. However, blood transfusion is not always without risks. The uncontrolled spreading of blood borne pathogens such as HIV or hepatitis B and C virus has urged researchers to look for “blood substitutes”. LÄS MER

  5. 24. Beam loss mechanisms in relativistic heavy-ion colliders

    Författare :Roderik Bruce; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The Large Hadron Collider (LHC), the largest particle accelerator ever built, is presently under commissioning at the European Organization for Nuclear Research (CERN). It will collide beams of protons, and later Pb ions, at ultrarelativistic energies. LÄS MER

  7. 25. Life Cycle Assessment (LCA) of Industrial Milk Production

    Författare :Merete Høgaas Eide; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dairy; cleaning; sustainability; packaging; LCA; Life Cycle Assessment; toxicity; milk;

    Sammanfattning : Life Cycle Assessment (LCA) was applied to milk production and processing in a study of the Norwegian dairy industry. This method, LCA, is used to assess the potential environmental impact of a material, product or service throughout its entire life cycle, from the extraction of the raw materials, the production process, and the user phase, to the final disposal.
