1. 1. Electron and proton transfer in cytochrome c oxidase

   Författare :Magnus Brändén; Peter Rich; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytochrome c oxidase; electron transfer; proton transfer; proton; Biochemistry; Biokemi; biokemi; Biochemistry; Biophysics; biofysik;

   Sammanfattning : This doctoral thesis describes results from studies on the mechanisms by which the enzyme cytochrome c oxidase catalyses the reduction of oxygen to water. Cytochrome c oxidase is the last integral enzyme complex of the socalled respiratory chain in the mitochondrial inner membrane (plasma membrane of bacteria). LÄS MER

3. 2. The Urban Tapestry : Essays on the Relationship Between Social Networks and Residential Segregation

   Författare :Laura Fürsich; Maria Brandén; Benjamin Jarvis; Sarah Valdez; Peter Rich; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social networks; Segregation; Agent-based modeling; Social infrastructure; Residential choice; Analytical sociology; Register data;

   Sammanfattning : Dominant explanations of segregation argue that patterns of spatial residential sorting are shaped by the aggregation of individual residential choices, guided by discrimination, differences in resources, and preference-based explanations of neighborhood ethnic composition. However, research on social networks indicates that social influence can serve as a driver of collective outcomes that result in social organization. LÄS MER

4. 3. Assembly characteristics of xylan rich extracts from birch

   Författare :Peter Westbye; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Xylan; Cellulose fibres; Adsorption; glucuronoxylan; Extraction; Aggregates; Solution properties;

   Sammanfattning : The greenhouse effect is one of the most important environmental problems that mankind has to solve. One solution could be the utilization of biomass to create new materials and fuels. Traditionally wood has been used as timber and as a raw material for pulp and paper production. LÄS MER

5. 4. Designing for the unknown : Didactical design for process-based assessment in technology-rich learning environments

   Författare :Peter Bergström; Brian Hudson; Gun-Marie Frånberg; Fredrik Paulsson; Anthony Rosie; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Process-based assessment; didactical design; technology; power; control; teacher; student; relationship; content; higher education; pedagogiskt arbete; educational work;

   Sammanfattning : This thesis is based on a study of the development of education through theinnovative use of process-based assessment in technology-rich learningenvironments in teacher and nurse education. The study of process-basedassessment addresses the aim of creating a better understanding of the shiftin emphasis from teaching to learning with regard to theory and practice. LÄS MER

7. 5. Two dimensions of student ownership of learning during small-group work with miniprojects and context rich problems in physics

   Författare :Margareta Enghag; Hans Niedderer; Peter Gustafsson; Jonte Bernhard; Phil Scott; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ownership of learning; exploratory talks; physics learning; context rich problems; miniprojects; Naturvetenskapernas och teknikens didaktik; fysikdidaktik; Ämnesdidaktik; Subject Didactics; Physics; Fysik; NATURAL SCIENCES; Naturvetenskapernas och teknikens didaktik;

   Sammanfattning : In this thesis the theoretical framework student ownership of learning (SOL) is developed both theoretically and with qualitative research, based on studies of small-group work in physics with miniprojects and context rich problems. Ownership is finally defined as actions of choice and control, i.e. LÄS MER
