1. Properties of Asphaltenes with emphasis on NMR self-diffusion as the investigating technique
Sammanfattning : Asphaltenes are high-molecular weight, highly aromatic molecules that have a strong tendency to aggregate. Asphaltenes are found in oil and may, if they form particles, cause problems during oil production and handling. LÄS MER
2. Recent trends in the epidemiology of gonorrhoea in Sweden : the role of importation and core groups
Sammanfattning : In 1997 the gonorrhoea incidence in Sweden started to rise from a low-prevalent level after some 25 years of steady decline. The rise has continued and coincides with similar trends in other sexual transmitted infections (STIs) and in other Western industrialized countries. LÄS MER
3. Molecular overlayers on homogeneous and heterogeneous metal surfaces studied by core-level photoemission
Sammanfattning : The main topic of this thesis is the investigation of small molecules adsorbed on metal surfaces by means of core-level photoemission spectroscopy. The thesis consists of three parts; The first group of papers concerns the effects of internal molecular vibrations on the core-level photoemission spectra. LÄS MER
4. Power from Below? : The Impact of Protests and Lobbying on School Closures in Sweden
Sammanfattning : In recent decades, there has been a considerable expansion of citizen participation in protests and voluntary advocacy groups. To analyze this development, the social movement literature and the interest group literature have emerged. LÄS MER
5. Input Calibration, Code Validation and Surrogate Model Development for Analysis of Two-phase Circulation Instability and Core Relocation Phenomena
Sammanfattning : Code validation and uncertainty quantification are important tasks in nuclear reactor safety analysis. Code users have to deal with large number of uncertain parameters, complex multi-physics, multi-dimensional and multi-scale phenomena. LÄS MER
