The work presented in this thesis concerns the preparation, characterization and film formation of a waterborne alkyd-acrylic hybrid system with high solids content of about 80 %. The alkyd-acrylic hybrids were prepared by slowly adding a linseed oil alkyd to an acrylic latex dispersion under stirring. In this work two acrylic dispersions with different glass transition temperatures were used in t

Popular Abstract in Swedish I "Vilket svenskämne? Grundskolans svenskämnen i ett lärarutbildningsperspektiv" beskrivs hur en grupp blivande 1 till 7-lärare förhåller sig till olika svenskämneskonceptioner genom lärarutbildningen. Avhandlingen har det dubbla syftet att analysera och tolka de studerandes svenskämneskonstruktioner och att institutionsanalytiskt granska utbildningen. Det empiriska matWhich Swedish?

Background. The thrombosis risk is increased in active ulcerative colitis. The limited number of reported complications have predominantly been cerebrovascular but other vessel territories may also be affected. Patient. During a severe attack of ulcerative colitis a 37-year-old woman suffered occlusion of all left coronary artery branches. Serial angiographies showed progressive recanalisation of

The effects of non-stoichiometry and isomorphic substitutions on the properties of some apatite-type compounds were investigated. These investigations were performed both in the fields of Portland cement chemistry and apatitic calcium phosphate-based biocements. Apatite compounds were synthesized by solid state methods and by hydrolysis of the reactant α-tricalcium phosphate (α-TCP). The materials

To support a more holistic approach to the contribution of packaging to efficiency and value creation in the product supply chain, a systematic evaluation method Packaging Scorecard - has been developed and tested in two case studies. The Packaging Scorecard is based on research of functional criteria of packaging and the theories of Balanced Scorecard, a general management approach to evalu

We analyze how firms hedge in the oil and gas industry. Our main finding is that CEO age determines hedging behavior. The probability of being a hedger as well as the use of linear hedging strategies decreases with CEO age. These results are consistent with an argument that financial distress, which sends a negative signal of managerial ability, is relatively more costly to younger CEOs. We also i

Competitiveness of city regions has gained a more and more central position in regional development and regional planning within the last decades. A reason for this is that globalisation has caused pressure on industrial structures forcing firms to increase their competitiveness by more actively promoting innovation and knowledge creation. Access to knowledge has therefore become vital for most ty

JGrafchart, a Java based implementation of the Grafchart sequencecontrol and procedure handling toolbox is presented. Examples of applicationswhere it is or will be used are given.

The cartilage extracellular matrix consists of the collagen network which enmeshes the large aggregating proteoglycan, aggrecan. Accessory molecules regulate the formation and maintenance of these structures. This thesis studies aspects of cartilage assembly during development and its degradation in disease, focusing on the collagen network. In the first paper, a model of cartilage degradation is
