    Sammanfattning : Rapeseed straw was fractionated through a hydrothermal process into its hemicellulose, lignin and cellulose components. In the first step, hemicellulose-rich fractions were extracted. Xylan-rich fractions with high molecular weight, 30,000 – 50,000 g/mol, were obtained at 110 °C and 1.5 M NaOH. LÄS MER

  3. 2. Methods for Automated Design of Fault Detection and Isolation Systems with Automotive Applications

    Författare :Carl Svärd; Mattias Nyberg; Erik Frisk; Mattias Krysander; Vincent Cocquempot; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Fault detection and isolation (FDI) is essential for dependability of complex technical systems. One important application area is automotive systems, where precise and robust FDI is necessary in order to maintain low exhaust emissions, high vehicle up-time, high vehicle safety, and efficent repair.

  5. 4. Emotional facial processing in younger and older adults

    Författare :Joakim Svärd; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : There is evidence that older adults have difficulty processing negative but not positive facial expressions. This positivity effect among older adults is expressed in attention to as well as in memory and recognition of emotional faces. In the present thesis, effects of stimulus properties (i.e. LÄS MER

  7. 5. Repressing the hedgehog signalling pathway

    Författare :Jessica Svärd; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The Hedgehog (Hh) signalling pathway is essential for metazoan development and aberrant activation of the pathway is found in tumours. Mutations in Hh pathway components are found in several tumour types, including basal cell carcinoma (BCC) and medulloblastoma (MB). LÄS MER
