Vitreoscilla is an obligate aerobic bacterium found in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla induces the production of a homodimeric hemoglobin (VHb) when subjected to oxygen-limiting conditions. It is thought that VHb facilitates oxygen delivery to the respiratory apparatus of its host by increasing the local oxygen concentration under oxygen-

The fact that a growing number of pathogens develop resistance against traditional treatment is a growing medical problem. Infections, which until now have been harmless, might turn into life threatening diseases. These problems have led to an intensified search for alternative treatments. Analogs of cell surface glycoconjugates are an alternative. Ideally they prevent the adhesion of the pathogen

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? Swedish as a school subject, from the perspective of teacher training describes how a group of future teachers of years 1 to 7 of the compulsory school relates to various concepts of the subject Swedish through three courses delivered at the School of Education. The study has the aim of analyzing the students' construction of the subject of Swedish as taught in school, and to analys

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
