  1. 31. Iron losses during desulphurisation of hot metal

    Författare :Marianne Magnelöv; Mårten Görnerup; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : After injection of calcium carbide and magnesium during desulphurisation of hot metal, the slag is normally solid and contains large amounts of iron. Besides the enclosed iron droplets in the slag, drawn-off hot metal during slag skimming also accounts for iron losses during desulphurisation of hot metal. LÄS MER

  3. 32. Electromagnetic Waves in Media with Ferromagnetic Losses

    Författare :Jörgen Ramprecht; Martin Norgren; Constantin Simovski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrophysics; Elektrofysik;

    Sammanfattning : The operation of a wide variety of applications in today's modern society are heavily dependent on the magnetic properties of ferromagnetic materials and their interaction with electromagnetic fields. The understanding of these interactions and the associated loss mechanisms is therefore crucial for the improvement and future development of such applications. LÄS MER

  5. 34. Voltage Losses in Non-fullerene Organic Solar Cells

    Författare :Yuming Wang; Feng Gao; Fengling Zhang; René Janssen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Non-fullerene acceptors have significantly boosted the efficiencies of organic solar cells (OSCs) in the past few years. State-of-the-art OSCs have achieved a certificated power conversion efficiency of 17.4%. LÄS MER

  7. 35. Work absenteeism and productivity losses associated with overweight

    Författare :Kristian Neovius; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Overweight has increased dramatically in the Western world during the past decades. The condition is associated with impaired health through, e.g., cardiovascular disease, musculo-skeletal disorders, type II diabetes, sleep apnoea and cancer. LÄS MER
