1. Concrete slab on the ground and moisture control : verification of some methods to improve the moisture conditions in the foundation
Sammanfattning : This work deals with different types of repair methods for concrete slab on the ground damaged by moisture. Many of the available methods involve some kind of mechanical ventilation of the foundation. The basic principle for all these systems is the same. LÄS MER
2. Soil improvement based on environmental geotechnics : environmental and geotechnical aspects of drainage of redox-sensitive soils and stabilisation of soils with by-products
Sammanfattning : I avhandlingen behandlas Miljögeotekniska problem som "dränering av redox-sensitiva jordar", "blockstabilisering av sulfidjord och torvjord" och " undersökning av nya vägmaterial". - Miljöproblem, kopplat till dränering och/eller urgrävning av redox-sensitiva jordar, som järnhaltiga moräner och sulfidjordar, behandlas i denna avhandling.

3. Dränerande sildammar för deponering av anrikningssand
Sammanfattning : Vid gruvbrytning genereras bland annat ett finmalet gråbergsavfall, anrikningssand. Den vanligaste deponeringsmetoden för anrikningssand är att den tillsammans med vatten pumpas eller leds till en gruvdamm. Där deponeras anrikningssanden genom sedimentation. Trots att det är den vanligaste deponeringsmetoden är den behäftad med svagheter. LÄS MER
4. People, Climate, and Inclusive Infrastructure : A thesis on design and planning in underserved neighbourhoods
Sammanfattning : This thesis is concerned with the processes of design and planning of infrastructure in rapidly urbanising cities that can lead to a more just and sustainable trajectory of urban development in the context of a changing climate. The thesis draws on case studies, panel surveys, interviews, and participant-observation of both top-down and bottom-up planning processes for infrastructure development and flood risk management in the context of urban informal areas, with a particular focus on the large informal neighbourhood of Kibera in central Nairobi, Kenya.

5. Spatial Variation in Near-Ground Radiation and Low Temperature - Interactions with Forest Vegetation
Sammanfattning : Low temperature has a large impact on the survival and distribution of plants. Interactive effects with high irradiance lead to cold-induced photoinhibition, which may impact on the establishment and growth of tree seedlings. LÄS MER
