  1. 1. Petrophysic of the Host-rock to the Ore in the Lovisa Mine, Bergslagen

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Oscar Gilljam Päärt; [2019]
    Nyckelord :Petrophysics; density; magnetic volume susceptibility; natural remanent magnetization; Bergslagen; lithology; Petrofysik; densitet; magnetisk susceptibilitet; naturlig magnetisk remanens; Bergslagen; lithologi;

    Sammanfattning : The Bergslagen region has three base-metal mines operating today, and one of them is the Lovisa mine, which host a Zn-Pb-Ag deposit. The Lovisa mine is located in the Guldsmedshyttan area north of Lindesberg. LÄS MER

  2. 2. MRI-based quantification of magnetic susceptibility: Assessment of measurement and calculation accuracy

    Master-uppsats, Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Emma Olsson; [2016]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : An object in an external magnetic field will be magnetized and the degree of magnetization is dependent of the magnetic susceptibility of the object. The local magnetic field inside and around an object in the MR scanner will change due to the magnetization of the object. LÄS MER

  3. 3. Integration of microfluidic sample handlingwith ultra-sensitive magnetic bioassay usinghigh-Tc Superconducting Quantum InterferenceDevice readout

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Emil Eriksson; [2016]
    Nyckelord :;

    Sammanfattning : Immunoassays are a very sensitive molecular diagnostics technique that uses biochemical reactions to measure concentration of biomolecules in a solution. ELISA is one of the most commonly used type, based on fluorescence, in routine medicaldiagnostics. It is time consuming and requires relatively large sample volumes. LÄS MER

  4. 4. Perfusion MRI: Non-Linear Stochastic Regularization for Deconvolution of Model-Free Arterial Spin Labelling Data

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Andre Ahlgren; [2011]
    Nyckelord :MRI; Medicine and Health Sciences;

    Sammanfattning : Introduction: Arterial spin labelling (ASL) is a non-invasive magnetic resonance imaging (MRI) technique for assessment of perfusion. ASL uses magnetically labelled blood water as a diffusible endogenous tracer to measure the perfusion of brain tissue, i.e. the cerebral blood flow (CBF). LÄS MER

  5. 5. Dynamic susceptibility contrast MRI calibrated using T1-based steadystate CBV and vascular space occupancy (VASO) Comparison with model-free arterial spin labelling

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Emelie Lindgren; [2009]
    Nyckelord :MRI; Medicine and Health Sciences;

    Sammanfattning : IntroductionThe perfusion-related parameters cerebral blood flow (CBF) and cerebral blood volume (CBV) can be measured using dynamic susceptibility-contrast magnetic resonance imaging (DSC-MRI). However, absolute values of CBF and CBV are often overestimated and quantification of these parameters is challenging. LÄS MER
