  3. 3. Fast-Neutron Tomography using a Mobile Neutron Generator for Assessment of Steam-Water Distributions in Two-Phase Flows

    Författare :Peter Andersson; Staffan Jacobsson Svärd; Henrik Sjöstrand; Stephan Pomp; Ane Håkansson; Michael Österlund; Bernhard Ludewigt; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Void distribution; neutron tomography; plastic scintillator; transmission measurements; neutron detection; Applied Nuclear Physics; Tillämpad kärnfysik;

    Sammanfattning : This thesis describes the measurement technique of fast-neutron tomography for assessing spatial distributions of steam and water in two-phase flows. This so-called void distribution is of importance both for safe operation and for efficient use of the fuel in light water reactors, which compose the majority of the world’s commercial nuclear reactors.

  4. 4. Optimization of Equipment for Tomographic Measurements of Void Distributions using Fast Neutrons

    Författare :Peter Andersson; Staffan Jacobsson Svärd; Henrik Sjöstrand; Ane Håkansson; Michael Österlund; Stephan Pomp; Rudi Van Nieuwenhove; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Physics; Fysik;

    Sammanfattning : This licentiate thesis describes a novel nondestructive measuring technique for determiningspatial distributions of two-phase water flows. In Boiling Water Reactors, which compose themajority of the world's commercial nuclear reactors, this so called void distribution is of importance for safe operation. LÄS MER

  5. 5. Exploration of bacteria associated with Anopheles mosquitoes around the world : For the prevention of transmission of malaria

    Författare :Louise K. J. Nilsson; Olle Terenius; Staffan Svärd; Sebastian Håkansson; Michael Strand; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; microbiota; microbiome; vector-borne disease; 16S rRNA gene; amplicon sequencing; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Every year, hundreds of thousands of people die from malaria. Malaria is a disease caused by parasites, which are spread by female vector mosquitoes of the genus Anopheles. Current control measures against malaria are based on drugs against the parasites and vector control using insecticides. LÄS MER
