1. Renewing power : Including global asymmetries within the system boundaries of solar photovoltaic technology
Sammanfattning : Solar photovoltaic (PV) technology is one of the most favored means of mitigating climate change. At the same time, there is a growing concern over how this technology is both environmentally harmful and unevenly distributed in the world economy. LÄS MER
2. Stable high-sensitivity cardiac troponin T levels and outcomes
Sammanfattning : Background: Many patients who seek medical attention because of chest pain in the emergency department (ED), without myocardial infarction (MI) as a final diagnosis, will have cardiac troponin (cTn) levels above the upper normal limit when measured with the high-sensitivity cardiac troponin T (hs-cTnT) assay. In patients with acute medical diseases other than MI which may affect hs-cTn levels, treatment strategies focus on underlying conditions. LÄS MER
3. Multi-Electron and Multi-Ion Coincidence Spectroscopy of Single-Photon Ionization Processes in Molecules
Sammanfattning : This thesis presents experimental investigations of multi-electron and multi-electron-multi-ion coincidence measurements of samples in the gas phase utilizing a versatile time-of-flight magnetic bottle spectrometer technique. These investigations of multiply ionized atomic and molecular species provide valuable information on, and understanding of, ionization processes and dissociation mechanisms highly relevant to the development of electronic structure theories.

4. Optical Characterization and Energy Simulation of Glazing for High-Performance Windows
Sammanfattning : This thesis focuses on one important component of the energy system - the window. Windows are installed in buildings mainly to create visual contact with the surroundings and to let in daylight, and should also be heat and sound insulating. LÄS MER
5. Optical Efficiency of Low-Concentrating Solar Energy Systems with Parabolic Reflectors
Sammanfattning : Solar electricity is a promising energy technology for the future, and by using reflectors for concentrating solar radiation onto photovoltaic cells, the cost per produced kWh can be significantly reduced. The optical efficiency of a concentrating system determines the fraction of the incident energy that is transferred to the cells and depends on the optical properties of the system components. LÄS MER
