  1. 21. Cancer imaging and image analysis methods in whole-body MRI and PET/MRI

    Författare :Therese Sjöholm; Joel Kullberg; Filip Malmberg; Robin Strand; Håkan Ahlström; Einar Heiberg Brandt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; diffusion weighted imaging; positron emission tomography; whole-body imaging; normal atlas; CAR T-cell therapy; lymphoma; medical image analysis; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Diagnostic medical imaging techniques such as magnetic resonance imaging (MRI) and positron emission tomography (PET) can provide structural and functional assessments of the whole body. This has great value for potentially systemic diseases such as cancer. LÄS MER

  3. 22. The Arctic Ocean Palaeomagnetic Record : A Stratigraphic Approach

    Författare :Steffen Wiers; Ian Snowball; Bjarne Almqvist; Matt O'Regan; Conall Mac Niocaill; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic Ocean; Stratigraphy; Diagenesis; Palaeomagnetism;

    Sammanfattning : The Arctic Ocean is an essential component of the global climate system, yet understanding of its geological archives is hampered by difficulties in age modelling. In addition to the scarcity of dateable microfossils, the palaeomagnetic record of Arctic sediments is unusual. LÄS MER

  4. 23. Performance of Magnetorheological Rubber Materials

    Författare :Mattias Lokander; Bengt Stenberg; Vince Coveny; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; magnetorheological rubber; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Magnetorheological (MR) rubber materials are the solid analogue of magnetorheological fluids; i.e. their rheological properties can be controlled continously, rapidly, and reversibly by an applied magnetic field. LÄS MER

  5. 24. Zeeman Interaction in Low-Dimensional III-V Semiconductor Structures

    Författare :Bernhard Kowalski; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optically detected spin resonance; spin resonance; effective g-value; III-V semiconductors; low-dimensional structures; quantum wells; quantum dots; Stranski-Krastanow; photoluminescence; GaInAs; single dot Magneto-luminescence; Fysicumarkivet A:1997:Kowalski; Halvledarfysik; Semiconductory physics; GaInAs-InP;

    Sammanfattning : The Zeeman interaction in low-dimensional III-V semiconductor nanostructures is studied. The effective g-value of bulk InGaAs is measured by two different spin resonance techniques. Experimental conditions were found to control the Overhauser effect, thus enabling a highly accurate determination of the g-value, g* = -4.070 ± 0. LÄS MER

  7. 25. Charge and Spin Transport in Parallel-Coupled Quantum Dots in Nanowires

    Författare :Malin Nilsson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2018:Nilsson;

    Sammanfattning : This thesis explores crystal-phase engineering of nanowires to fabricate advanced quantum structures for charge and spin transport studies. Quantum dots formed by crystal-phase tuning during epitaxial growth of InAs nanowires were used as a starting point to realize and electrically characterize two different types of parallel-coupled quantum dots; electron-hole quantum dots and electron-electron quantum dots.
