1. 1. Myocardial Perfusion and Function: Comparative assessment by ECG, SPECT and MRI

   Författare :Eva Persson; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; medicinsk instrumentering; Physiology; radiologi; radiology; tomography; medical instrumentation; Klinisk fysiologi; Clinical physics; ST-segment deviation ; myocardial ischemia ; myocardial perfusion ; MRI; CMR; MPS; ECG; SPECT; Fysiologi; Cardiovascular system; myocardial function ; Kardiovaskulära systemet;

   Sammanfattning : Evaluation of myocardial perfusion and function is important in management of patients with suspected or known coronary artery disease. This thesis focuses on the use of common diagnostic methods, myocardial perfusion single-photon emission computed tomography (MPS) and electrocardiography (ECG), to enhance and validate the diagnostic information.

3. 2. Triptych of quantum matter in one dimension : Playful constructions in theoretical and computational physics

   Författare :Axel Gagge; Jonas Larson; Andrew Daley; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bloch oscillations; Peierls; adiabatic; diabatic; ultracold atoms; Bose-Fermi mixtures; phonon; cQED; superradiance; polarons; DMRG; MPS; Kosterlitz-Thouless; Wannier; Bloch; quantum phase transitions; Theoretical Physics; teoretisk fysik;

   Sammanfattning : In this compilation thesis, three different quantum mechanical systems are presented. All three have in common that they are one-dimensional quantum systems which, each in their own way, can be seen as analogous to other quantum systems. LÄS MER

4. 3. Traffic-related pollutants in urban snow : Concentrations, size fractionation, and release with snowmelt

   Författare :Arya Vijayan; Maria Viklander; Helene Österlund; Göran Blomqvist; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban snow; Traffic pollution; Suspended solids; Metals; PAHs; Tire and Road wear Particles T RWPs ; Microplastics MPs ; Size fractionation; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

   Sammanfattning : In urban areas with seasonal snow, traffic-related pollutants such as solid particles, metals, chloride, organic pollutants, and microplastics (MPs) can be temporarily stored in snowbanks along roads and streets. When the snow melts, it releases the accumulated pollutants and the resulting snowmelt with diverse pollutants may partly infiltrate into the ground, or enter storm sewers and eventually be discharged into, and impact on, the receiving waters.
