  1. 1. Potential Flow Panel Methods for the Calculation of Free-surface Flows with Lift

    Författare :Carl-Erik Janson; Chalmers tekniska högskola; []

    Sammanfattning : Two non-linear Rankine-source panel methods are developed and implemented in the same computer code. The first method uses a four-point upwind operator on the free-surface to compute the velocity derivatives and to enforce the radiation condition while the second method uses an analytical expression for the velocity derivatives and a collocation point shift one panel upstream to prevent upstream waves.

  3. 2. Pedicled and free TRAM flaps in breast reconstructions : a comparative study

    Författare :Åsa Edsander-Nord; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :breast reconstruction; TRAM; pedicled flap; free flap; microdialysis; monitoring; flap circulation; flap metabolism; glucose; lactate; glycerol; abdominal muscles; trunk muscle strength; KIN-COM; quantitative sensory testing; tactile perception threshold; thermal perception threshold; breast volume; thermoplastic; quality of life; SF-36; esthetic evaluation; applanation tonometry;

    Sammanfattning : The transverse rectus abdominis musculocutaneous (TRAM) flap is frequently used when autologous tissue is desired for breast reconstruction, and it can be transferred pedicled or free. The pedicled TRAM flap is elevated as a lower transverse abdominal flap with the rectus abdominis muscle attached in the epigastric area, by which means the deep superior epigastric vessels nourish the flap.

  4. 3. At the intersection of proteomics and pathology : application of mass spectrometry-based protein quantification to histopathology and antibody validation

    Författare :Fabio Socciarelli; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The paradigm of Precision Medicine relies on the molecular stratification of patients to select “the right patient for the right drug”. The genomic approach has tried to answer this question, but large genomic studies have raised more questions than given answers. LÄS MER
