1. Varför gör vi inte som vi säger? : Realitet, retorik och dialektik i svensk stadsutveckling med fokus på energi och fysiska strukturer
Sammanfattning : In this doctoral thesis, case-studies on comprehensive planning and urban development in two Swedish municipalities reveals explanations and answers to how urban form that affects energy use and climate has changed between 1990-2010, how visions and goals are expressed in planning documents and what might cause the gap between the rhetoric of planning and the reality of urban development concerning energy and climate issues.Several methods are used under the canopy of case study methodology and an abductive research approach; time-series analysis with GIS-indicators to measure changes in urban structure; discourse analysis with a focus on rhetoric and interviews with responsible planning officials using a range of dialectics-based concepts as a framework to reveal hidden structures and mechanisms behind the gap.

2. Computational Biomechanics in Cross-country Skiing
Sammanfattning : Traditionally, research on cross‐country skiing biomechanics is based mainly on experimental testing alone. Trying a different approach, this thesis explores the possibilities of using computational musculoskeletal biomechanics for cross‐country skiing. As far as the author knows, this has not been done before. LÄS MER
3. Cobalt and Nickel Bioavailability for Biogas Formation
Sammanfattning : Supplementation of trace metals such as Co and Ni may improve anaerobic digestion of organic material for biogas formation. Which trace metals that are needed and the quantity to apply are, at least partly, related to metal speciation and bioavailability. LÄS MER
4. Microstructure Formation and Mechanical Properties in Compacted Graphite Iron
Sammanfattning : Compacted graphite iron is rapidly becoming an attractive alternative for engine applications in the automotive industry. The improved process control now available that allows CGI components to be cast in a reproducible and reliable way has been the driving force for this development. LÄS MER
5. Microstructure Formation During Solidification and Solid State Transformation in Compacted Graphite Iron
Sammanfattning : Compacted graphite iron (CGI) is rapidly becoming an attractive alternative material for engine components in the automotive industry, replacing lamellar graphite iron (LGI) in applications where high mechanical strength is desired. However, the gain in mechanical strength comes with a cost; thermal conductivity, process control and machining are three areas that are more challenging for CGI. LÄS MER
