2. 1. Aspects of Crack Growth in Single-Crystal Nickel-Base Superalloys

   Author : Christian Busse; Daniel Leidermark; Kjell Simonsson; Johan Moverare; David Gustafsson; Björn Sjödin; Louis J. Ghosn; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This Licentiate of Engineering thesis is a product of the results generated in the research project KME-702, which comprises modelling, microstructure investigations and material testing of cast nickel-base superalloys.The main objective of this work is to model the fatigue crack propagation behaviour in single-crystal nickel-base superalloys.

4. 2. Thermal response tests : influence of convective flow in groundwater filled borehole heat exchanger

   Author : Anna-Maria Gustafsson; Jeffrey D. Spitler; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

   Abstract : The main objective of this doctorial thesis was to investigate how thermally induced movements in the groundwater (natural convective flow) may influence the heat transport in borehole and surrounding bedrock in a groundwater filled borehole heat exchanger system. The purpose was also to determine if thermal response tests could be used to detect the convective influence and the effect on evaluated heat transfer parameters, effective bedrock thermal conductivity and borehole thermal resistance.

5. 3. Ships, clouds, and waves : understanding ecosystems in traditional industries

   Author : Peter Gustafsson; Zsuzsanna Vincze; Sujith Nair; Llewellyn D.W. Thomas; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ecosystems; Orchestration; Emergence; Traditional Industries; Shipbuilding; Resource Dependence Theory; Collective Action Theory; Corporate Political Activity;

   Abstract : This dissertation builds on a jointly phenomenological and theoretical approach to investigate how traditional industries face challenges related to ecosystem innovation. Phenomenologically, it investigates how innovation within the shipbuilding industry affects the activities performed by firms that have traditionally filled the role of suppliers to shipyards.

6. 4. Uptake and toxicity of brominated flame retardants and pesticides : Studies on littoral organisms and model communities

   Author : Kerstin Gustafsson; Nils Kautsky; Kirsten Christoffersen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; aquatic ecotoxicology; ecological interactions; indirect effects; model community studies; toxicity; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Abstract : In this thesis, brackish and freshwater littoral model communities (microcosms) of varying size and complexity were used to study the effects of brominated flame retardants (BFRs) and pesticides. The brackish water microcosms consisted of natural water, sediment and associated organisms, while the larger freshwater microcosms also contained submersed macrophytes (Elodea canadensis).

7. 5. Structural and functional studies of proteins of medical relevance : Protein-ligand complexes in cancer and novel structural folds in bacteria

   Author : Robert Gustafsson; Pål Stenmark; Pavlína Řezáčová; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray crystallography; Cancer; MTH1; oxidised nucleotides; MTHFD2; nucleotide metabolism; one-carbon metabolism; Botulism; Botulinum neurotoxin; OrfX; OrfX gene cluster; Biochemistry; biokemi;

   Abstract : X-ray crystallography is a tool for determining the structures of proteins and protein-ligand complexes. In this thesis the method has been employed to study several proteins of medical relevance.Cancer is a terrible disease, severely impacting those affected, as well as their family and friends.
