  1. 1. Geophysical Data from Norrbotten, Sweden - Evidence for the Presence of a Crustal Scale Fault?

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Jimmy Markström; [2022]
    Nyckelord :Self-Organizing Maps; Magnetic Anomaly; Radioisotopes; Geological Faults;

    Sammanfattning : The method of combining multiple geophysical, geological, or geochemical datasets can reveal patterns of otherwise hidden features in the Earth’s crust. This may aid in geological mapping, locating economic mineral deposits and for general anomaly/feature detection. LÄS MER

  3. 2. Radiojodbehandling vid Graves sjukdom: långvarig effekt och påverkan på livskvalitet

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Klara Vareman; [2021]
    Nyckelord :Graves´ disease; iodine radioisotopes; quality of life; treatment outcome; Graves sjukdom; radiojodbehandling; livskvalitet; behandlingsresultat;

    Sammanfattning : Bakgrund: Graves sjukdom är den vanligaste formen av hypertyreos med en incidens på 20 fall per 100 000 individer och år. Graves sjukdom är ett autoimmunt tillstånd där autoantikroppar riktade mot tyreoideastimulerande hormonreceptorer (TSH-R) orsakar okontrollerad syntes och sekretion av tyreoideahormonerna trijodtyronin (T3) och tyroxin (T4).

  4. 3. TLD Measurements on Patients being treated with a Taylor Spatial Frame : Using Radiation from Na18F PET/CT Studies and from Naturally Occurring Radioisotopes

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Kousha Mirzadeh; [2014]
    Nyckelord :Taylor Spatial Frame; Thermoluminescent dosimeters; Tibia fracture; Bone remodeling; Na18F; PET CT; Bone seeking radionuclide;

    Sammanfattning : Background: In an ongoing study conducted at Karolinska Institutet & Karolinska University Hospital, Positron Emission Tomography (PET)/Computed Tomography (CT) scans are performed on patients with tibia fractures and deformations treated with Taylor Spatial Frames (TSFs) in order to monitor their bone remodeling progress. Each patients receive an administration of approximately 2 MBq/kg bodyweight of Na18F associated with PET scans on two sessions, six and twelve weeks after the attachment of the TSF. LÄS MER

  5. 4. Influence of depositional mobility (downwashing) on the accumulation of atmospherically supplied elements in peat cores: an experimental approach

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Keyao Chen; [2014]
    Nyckelord :;

    Sammanfattning : The potential influence of downwashing on atmospherically deposited elements is of rare focus compared with other geochemical processes related to peat. Downwashing may cause a rapid downward movement of atmospherically supplied elements before they bond to the peat organic substrate and thus reduce the reliability of age-depth models that rely on atmospherically supplied radioisotopes (e.

  7. 5. Three-Dimensional Quantitative Cerenkov Luminescence Imaging

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Författare :Anton Ajne; [2014]
    Nyckelord :Cerenkov; CLI; Optical imaging; Nuclear medicine; Biology and Life Sciences;

    Sammanfattning : Cerenkov luminescence imaging (CLI) is an up-and-coming optical technique for in vivo imaging of beta-emitting radioisotopes. CLI relies on measurements of the Cerenkov radiation emitted when high-energy beta-particles travel through tissue. LÄS MER
