16. Insights into Materials Properties from Ab Initio Theory : Diffusion, Adsorption, Catalysis & Structure
Abstract : In this thesis, density functional theory (DFT) calculations and DFT based ab initio molecular dynamics simulations have been employed in order to gain insights into materials properties like diffusion, adsorption, catalysis, and structure. In transition metals, absorbed hydrogen atoms self-trap due to localization of metal d-electrons. READ MORE

17. Past demography and local adaptation in forest trees : Insights from natural populations and breeding programs of Norway spruce
Abstract : Spatial changes in natural selection patterns can give rise to local adaptation and genetic differentiation between populations. Local adaptation for phenological traits is pronounced in many forest tree species. READ MORE

18. Rare-gas Clusters Studied by Electron Spectroscopy : Structure of Heterogeneous Clusters and Effects of Electron Scattering on Auger Decay
Abstract : In this Thesis experimental studies of nano-clusters using synchrotron radiation based photoelectron (UPS and XPS) and Auger Electron Spectroscopy (AES) are presented. The investigations may be divided into two parts where the first reports on the structure of heterogeneous two component clusters, and the second concerns electronic decay processes. READ MORE

19. Nonfatal injuries in a local context - Analysing social structures and perceptions in young people
Abstract : Background: Injuries are a common health problem in children and young people. The uneven distribution over gender and socioeconomic groups is partly explained by factors at both the individual and family levels, but sociocultural structures at the municipality level may contribute with yet unrecognised associations.

20. Galactic Structure Revealed by Space Astrometry
Abstract : This work demonstrates how the structure of our Galaxy, the Milky Way, can be unveiled with the use of space astrometry. It consists of two parts, of which the first is a brief introduction to the fields of Galactic structure, covering the Galaxy's stellar constituents, how the Galaxy was formed and how it has evolved over time, both chemically and kinematically.
