1. Kinematics and Internal Deformation of Granular Slopes
Sammanfattning : Flow-like mass movement is the most destructive landslide and causes loss of lives and substantial property damage throughout the world every year. This thesis focuses on the spatial and temporal changes of the mass movement in terms of velocity and displacement within the failure mass, and the spatial and temporal distribution of the three dimensional internal deformation of the granular slopes using discrete element method, physical experiments, and natural landslides.

2. Werden – ein Chamäleon der Sprache : Zum Werdegang von werden
Sammanfattning : The topic of this thesis is the evolutionary history of werden in German with reference to its four functions – as full verb, as copula and as auxiliary verb in combination with the past participle in the Vorgangspassiv and also in combination with the infinitive to denote future and, in some circumstances, epistemic modal events. On the basis of scrutiny of diachronic results and a discussion of views put forward in the synchronic literature and empirically corroborated by a detailed analysis of a corpus, it is argued that the unique position of werden in the German verb arena was made possible by its non-specified meaning of dynamic existence, by its medial, non-agentive diathesis and, crucially, by its additivity, and its actional and aspectual underdetermination.

3. Lake Dissolved Organic Matter Quantity and Quality : Variability across Temporal and Spatial Scales
Sammanfattning : Surface waters receive large amounts of dissolved organic matter (DOM) via runoff from land. The DOM is rich in organic carbon that serves as an energy source for the aquatic biota. During uptake of this energy, aquatic organisms mineralize organic carbon. LÄS MER
4. Hygroscopic Properties of Aerosols from Open-Air Burning and Controlled Combustion of Biomass
Sammanfattning : The major uncertainty in predicting the influence of human activities on global climate change is the effect of aerosols. Two physical properties of aerosols largely controlling their influence on climate are the particle number size distribution and the interaction of the particles with the surrounding water vapor.

5. X-ray microtomography and digital volume correlation for internal deformation and strain analysis
Sammanfattning : A material that is exposed to mechanical load or experience a variation in its immediate environment (temperature, pressure, humidity etc.) will to some extent be affected by these new conditions, which is reflected through structural movements in the material. LÄS MER
