  1. 31. Proteolytic activation and biological functions of the novel PDGFs

    Författare :Linda Fredriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The platelet-derived growth factors (PDGFs) and their cell surface receptors regulate growth and migration of connective tissue cells of both the vascular network and other organ systems. They are known to be important for normal development and processes, such as wound healing and angiogenesis, but have also been implicated in many pathological conditions, such as malignancies and fibrotic disease.

  3. 32. Class of Accurate Low Order Finite Elements

    Författare :Magnus Fredriksson; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quadrilateral ; variational ; finite element ; element technology ; HuWashizu ; hexahedral ; Technological sciences; Teknik;

    Sammanfattning : High accuracy and low computational costs are essential properties for efficient finite element codes. Improvements of the finite element method in order to satisfy these qualities have been the subject for extensive research activities ever since its introduction. LÄS MER

  4. 33. Computer simulation in the forestry-wood chain

    Författare :Magnus Fredriksson; Dan Olofsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : The forestry-wood chain today involves many actors, and the decisions taken in the process of making trees into finished products are so many that the effect of each individual decision is difficult to assess, especially if the natural variation of the input material is considered.This means that a simulation approach to the forestry-wood chain is suitable, since it makes it possible to evaluate the effects of decisions in a short timeframe, while the input material can be kept constant for different production setups.

  5. 34. Efficient algorithms for highly automated evaluation of liquid chromatography - mass spectrometry data

    Författare :Mattias Fredriksson; Dan Bylund; Patrik Petersson; Bengt-Olof Axelsson; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital filtering; Liquid chromatography; Mass spectrometry; Method; Chemistry; Kemi;

    Sammanfattning : Liquid chromatography coupled to mass spectrometry (LC‐MS) has due to its superiorresolving capabilities become one of the most common analytical instruments fordetermining the constituents in an unknown sample. Each type of sample requires a specificset‐up of the instrument parameters, a procedure referred to as method development. LÄS MER

  7. 35. Epidemiological studies on colorectal cancer : Some design issues and analytical considerations

    Författare :Mats Fredriksson; Bengt Järvholm; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Determinants of colon and rectal cancer have been studied in two case-control data sets, one from the north of Sweden, i.e., Norrland, and the other from the county of Östergötland. LÄS MER
