  1. 1. Electron beam profile measurements and emittance manipulation at the MAX-laboratory

    Detta är en avhandling från MAX-lab, Lund University

    Författare :Åke Andersson; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optics; quantum excitation; emittance; synchrotron radiation; electron beam; lattice; Accelerator; storage ring; diffraction; Physics; Fysik;

    Sammanfattning : The emittances of the electron beams at the MAX-laboratory accelerator system have been studied. Apart from the build-up of the diagnostic tools for precise determination of the beam spatial profiles, the objectives have been: a) to verify the accelerator design emittances at low currents and to try to determine the emittances also at high currents; b) to investigate possibilities to manipulate the emittances.

  2. 2. Circulating Biomarkers in Patients with Head and Neck Cancer and the Influence of Cigarette Smoking

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Bengt-Åke Andersson; Linköpings universitet.; Linköpings universitet.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Head and neck cancer (HNC) is a collective name for heterogeneous tumors located in the head and neck regions for which smoking, alcohol and human papillomavirus (HPV) are documented risk factors. The survival of HNC patients has only improved marginally during the last decade. LÄS MER

  4. 4. Computation of Thermal Development in Injection Mould Filling, based on the Distance Model

    Detta är en avhandling från Matematiska institutionen

    Författare :Per-Åke Andersson; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermoplastic materials; finite element FEM ; finite difference FD ; Newton-Mysovskii theorem; Moldflow Mfl ; Cadmould Cmd ; MATHEMATICS; MATEMATIK;

    Sammanfattning : The heat transfer in the filling phase of injection moulding is studied, based on Gunnar Aronsson’s distance model for flow expansion ([Aronsson], 1996).The choice of a thermoplastic materials model is motivated by general physical properties, admitting temperature and pressure dependence.
