  1. 1. Integration of MRI into the radiotherapy workflow

    Författare :Joakim Jonsson; Tufve Nyholm; Mikael Karlsson; Magnus Karlsson; Uulke van der Heide; Umeå universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; magnetic resonance imaging; radiotherapy; treatment planning; image registration; workflow; radiofysik; radiation physics;

    Sammanfattning : The modern day radiotherapy treatments are almost exclusively based on computed tomography (CT) images. The CT images are acquired using x-rays, and therefore reflect the radiation interaction properties of the material. LÄS MER

  2. 2. Energy and intensity modulated radiation therapy with electrons

    Författare :Lennart Olofsson; Mikael Karlsson; Magnus Karlsson; Björn Zackrisson; Erik Traneus; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Radiation therapy; Conformal therapy; IMRT; Electrons; Electron treatment head; Electron MLC; Bremsstrahlung reduction; Integral dose; Penumbra; Output factor; Strålningsvetenskap; Radiation biology; Strålningsbiologi; radiofysik; radiation physics;

    Sammanfattning : In recent years intensity modulated radiation therapy with photons (xIMRT) has gained attention due to its ability to reduce the dose in the tissues close to the tumour volume. However, this technique also results in a large low dose volume. LÄS MER

  3. 3. Aeroacoustics Studies of Duct Branches with Application to Silencers

    Författare :Mikael Karlsson; Mats Åbom; Luc Mongeau; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silencer; muffler; confined flows; flow duct; aeroacoustics; vortex sound; acoustic multiports; linear stability; self-sustained oscillations; whistling; Herschel-Quincke tube; acoustic resonator; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : New methodologies and concepts for developing compact and energy efficient automotive exhaust systems have been studied. This originates in the growing concern for global warming, to which road transportation is a major contributor. LÄS MER

  4. 4. Fc receptors and feedback regulation by antibodies

    Författare :Mikael Karlsson; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Mouse; B lymphocytes; Fc; receptors; IgG; IgE; FcgRI; FcgRII; FcgRIII; Fc e RI; CD23; Rh prophylaxis; Haemolytic disease of the newborn; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Sammanfattning : The purpose of this investigation was to determine the role of Fc receptors for IgG (FcγRI, FcγRIIB, FcγRIII and FcRn) in immunoregulation. IgG is known to enhance the response to soluble antigens such as bovine serum albumin whereas the response to particulate antigens is suppressed. LÄS MER

  5. 5. ”Gå eller rulla – Alla vill knulla!” : Funktionsrättsaktivism i nyliberala landskap

    Författare :Mikael Karlsson; Genusvetenskapliga institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social movements; civil society; neoliberalism; Crip theory; disability activism; sexual politics; extended case studies; institutional ethnography; Social movements; Civil Society; neoliberalism; Crip theory; disability activism; sexual politics; extended case studies; Institutional ethnography;

    Sammanfattning : This study follows groups in Sweden that are involved in a political struggle to change norms regarding sexuality and disability. The groups are mostly connected to the disability movement or the movement of sexual politics. LÄS MER
