  3. 2. Quantitative Genetics and Genome Structure in a Wild Population: the Use of a Great Reed Warbler Pedigree

    Författare :Mikael Åkesson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; genome mapping ; AFLP; microsatellite; synteny; heterochiasmy; recombination; chicken; great reed warbler ; bird; Genetics; cytogenetics; Genetik; cytogenetik; Animal ecology; trait correlation ; Djurekologi; animal model ; selection; Djurs anatomi och morfologi; animal morphology; Animal anatomy; heritability;

    Sammanfattning : Long-term studies of birds play an important role in the understanding of quantitative traits in natural populations. The relative ease by which individual birds can be monitored and caught in the wild enable us collect detailed information from individuals throughout their life time, sometimes from several generations in a population.

    Sammanfattning : Measurements of process variations and particle morphology are widely employed in the pulp and paper industry. Two techniques with high potential, infrared thermography and microparticle characterisation, are mainly used qualitatively. LÄS MER

  5. 4. Methodological improvements in quantitative MRI : Perfusion estimation and partial volume considerations

    Författare :André Ahlgren; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The magnetic resonance imaging (MRI) scanner is a remarkable medical imaging device, capable of producing detailed images of the inside of the body. In addition to imaging internal tissue structures, the scanner can also be used to measure various properties of the tissue. LÄS MER

  7. 5. Optimisation and Validation of Dynamic Susceptibility Contrast MRI Perfusion Measurements

    Författare :Linda Knutsson; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nukleärmedicin; radiobiologi; Nuclear medicine; radiobiology; radiologi; tomografi; medicinsk instrumentering; tomography; medical instrumentation; Clinical physics; cerebral blood volume; mean transit time; cerebral blood flow; perfusion; dynamic susceptibility contrast MRI arterial input function; Klinisk fysiologi; radiology;

    Sammanfattning : The studies presented in this thesis concern the optimisation and evaluation of the dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) technique for the assessment of perfusion-related parameters of the brain, such as cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT). Several methodological factors influence these measurements, for example, contrast-agent administration, arterial input function (AIF) registration, choice of deconvolution algorithm and the choice of pulse-sequence parameters.
