  1. 1. High-speed 3D imaging of liquid jets, surfaces and respiratory droplets

    Författare :Adrian Roth; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Laser Induced Fluorescence; Volumetric imaging; Structured Illumination; 3D Reconstruction; Stereoscopy; 3D Particle Tracking Velocimetry; COVID­19; sprays; respiratory droplets; Fysicumarkivet A:2023:Roth;

    Sammanfattning : Sprays are commonly found in, among other, combustion, agriculture and food processing. For each of these applications, the understanding of spray liquid dynamics is crucial for optimization of efficiency, accuracy, and robustness of the spray­-system in use. LÄS MER

  3. 2. Computational and experimental methods for imaging and dosimetry in 177Lu radionuclide therapy : Classical and novel gamma cameras

    Författare :Daniel Roth; Lund Medicinsk strålningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radionuklidterapi; [177Lu]Lu-DOTA-TATE; Gammakamera; Aktivitetskvantifiering; Dosimetri; CdZnTe; Monte Carlo; Radionuclide therapy; [177Lu]Lu-DOTA-TATE; Gamma camera imaging; Activity quantification; Dosimetry; CdZnTe; Monte Carlo;

    Sammanfattning : Radionuclide therapy (RNT) is a form of radiotherapy that uses unsealed radioactive sources for the delivery of ionising radiation within a patient's body.Radiation dosimetry is not used routinely in all centres, and the RNT field can benefit from more data on pharmacokinetics and absorbed doses (ADs).

  4. 3. Functions of Pericytes in Ischemic Stroke

    Författare :Michaela Roth; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stroke; Pericytes; RGS5; Blood-brain barrier; vascular remodelling; scar formation;

    Sammanfattning : Ischemic stroke remains one of the leading causes of death and disability worldwide, and its burden is predicted to further increase due to the aging population. The only available treatments, thrombolysis or thrombectomy, can only be applied within a limited time window after stroke onset, and thus are applicable only to a small proportion of stroke patients.

  5. 4. Spectroscopy along Decay Chains of Element 114, Flerovium

    Författare :Anton Såmark-Roth; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superheavy elements; Flerovium; Nuclear Structure; Spectroscopy; Alpha decay; Electromagnetic decay; Spontaneous fission; Germanium detectors; Fysicumarkivet A:2021:Såmark-Roth;

    Sammanfattning : This thesis focusses on a nuclear spectroscopy experiment conducted to study α-decay chains stemming from isotopes of flerovium (element Z = 114). An upgraded TASISpec decay station was placed behind the gas-filled separator TASCA at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany. LÄS MER

  7. 5. Fat metabolism during total parenteral nutrition: A biochemical and ultra-structural study

    Författare :Bengt Roth; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; Intravenous Fat Emulsion - Lipid Metabolism - Lipoprotein lipase - Kupffer cells - - Histology - Fatty liver - Adverse reactions - Haemophagocytosis; intensive care; Anestesiologi; intensivvård;

    Sammanfattning : This thesis evaluates alterations in lipid metabolism and Kupffer cell morphology seen during total parenteral nutrition in healthy rats. During infusion of lipid emulsions, cholesterol and phospholipids accumulated in non-high density lipoproteins, while high density lipoproteins were enriched in triglycerides. LÄS MER
