1. Quality of snow deposited in urban areas : Storage, load assessment and release of selected pollutants with snowmelt
Sammanfattning : Snow deposited in urban areas is exposed to pollutants originating from traffic, wet and dry atmospheric deposition, de-icing chemicals and traction materials. The conventional pollutants found in urban snow include solids (TSS), metals (Zn, Cu, Cd, Pb, etc.), Polycyclic Aromatic Hydrocarbons (PAHs), and chlorides. LÄS MER
2. Studies of molecular clouds at the Galactic centre
Sammanfattning : Interstellar molecular clouds play an essential role in the Universe. Such clouds are invoked for the production and destruction of stars, galaxies and gas and also for energy transport in galaxies. LÄS MER
3. Theoretical Studies of Binaries in Astrophysics
Sammanfattning : This thesis introduces and summarizes four papers dealing with computer simulations of astrophysical processes involving binaries. The first part gives the rational and theoretical background to these papers. In paper I and II a statistical approach to studying eclipsing binaries is described. LÄS MER
4. Altered body composition in adults with complex congenital heart disease
Sammanfattning : Introduction: Thanks to achievements in paediatric heart surgery and medicine, the population of adults with surgically repaired or palliated congenital heart defects is growing. Many of these adults have reduced exercise capacity, weaker muscular strength and shorter height, all of which suggest an altered body composition. LÄS MER
5. Interactions of chiral ions and molecules in gas phase : Towards an understanding of chiral recognition mechanism
Sammanfattning : This thesis comprises the research related to interactions of enantiopure amino acids with chiral and achiral molecules in gas phase. The investigation of the mechanism responsible for chiral discrimination is of the special interest in this work. LÄS MER
