  2. 1. Characterization and Clinical Application of Normoxic Polymer Gel in Radiation Therapy Dosimetry

    Author : Anna Karlsson; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D dose verification; uncertainties; low-density gel; fractionation dependence; characterization; normoxic gel; polymer gel dosimetry; MRI; Physics; Fysik;

    Abstract : Cancer is one of the main causes of death in the world, particularly in developing countries and is considered as a major public health problem. Radiation therapy has been an important modality for treatment of cancer for many decades. READ MORE

  4. 2. Source-Receptor Modeling of Air Pollution : Assessment of Source Contributions: Source Characterization and Chemometric Applications

    Author : Emma Hedberg Larsson; Christer Johansson; H.-C. Hansson; Ralf Torgrip; Paulo Artaxo; Stockholms universitet; []
    Keywords : Particles; Source-receptor modeling; PMF; Elemental source profiles; Levoglucosan; Wood combustion; Air pollution; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Particles released to the atmosphere from anthropogenic sources affect the Earth’s climate as well as the health of the population. Anthropogenic sources of atmospheric particles are e.g. the combustion of biomass and fossil fuels, road, brake and tire wear and various industrial activities. READ MORE

  5. 3. Aspects on probabilistic approach to design : From uncertainties in pre-investigation to final design

    Author : Anders Prästings; Stefan Larsson; Rasmus Müller; Jan Laue; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability-based design; Geotechnical design; Geotechnical structures; Sheet-pile wall; Characterization of uncertainties; Geotechnical investigations;

    Abstract : Geotechnical engineering is strongly associated with large uncertainties. Exploring a medium (soil) that is almost entirely and completely hidden from us is no easy task. Investigations can be made only at discrete points, and the majority of a specific soil volume is never tested. READ MORE

  6. 4. New aspects of electronic interactions of keV ions with matter

    Author : Barbara Bruckner; Daniel Primetzhofer; Peter Bauer; Marika Schleberger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ToF-MEIS; LEIS; electronic stopping; charge exchange; scattering potential; Fysik; Physics;

    Abstract : Low- and medium-energy ion scattering are powerful techniques to perform high-resolution depth profiling with sub-nanometer resolution. Typically, ions with primary energies between a few keV and a few hundred keV are used to probe the sample and backscattered projectiles are detected. READ MORE

  7. 5. 3D Time-lapse Analysis of Seismic Reflection Data to Characterize the Reservoir at the Ketzin CO2 Storage Pilot Site

    Author : Fei Huang; Christopher Juhlin; Alireza Malehmir; Ari Tryggvason; Andy Chadwick; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2 storage; 3D Time-lapse 4D ; Reservoir characterization; Seismic simulation; Spectral decomposition; Wavelet phase; Tuning frequency; Thin-layer thickness; Seismic monitoring; Seismic processing; Quantitative interpretation; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : 3D time-lapse seismics, also known as 4D seismics, have great potential for monitoring the migration of CO2 at underground storage sites. This thesis focuses on time-lapse analysis of 3D seismic reflection data acquired at the Ketzin CO2 geological storage site in order to improve understanding of the reservoir and how CO2 migrates within it.
