2. Genomic and morphological diversity of marine planktonic diatom-diazotroph associations : a continuum of integration and diversification through geological time
Sammanfattning : Symbioses between eukaryotes and nitrogen (N2)-fixing cyanobacteria (or diazotrophs) are quite common in the plankton community. A few genera of diatoms (Bacillariophyceae) such as Rhizosolenia, Hemiaulus and Chaetoceros are well known to form symbioses with the heterocystous diazotrophic cyanobacteria Richelia intracellularis and Calothrix rhizosoleniae.

3. Ethyl(hydroxyethyl)cellulose and Some Model Uncharged Polymers: A Calorimetric Study of Their Interaction with Surfactants in Aqueous Solution
Sammanfattning : The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. LÄS MER
4. Interaction between rider, horse and equestrian trainer : a challenging puzzle
Sammanfattning : This thesis examines the complex and challenging relationships between rider, horse and equestrian trainer in the context of teaching horse riding. What strategies and methods do equestrian trainers use to support the riders’ understanding of, and performance with, their horses? What role is the horse assigned in this form of interaction? Operating at the intersection between practical knowledge and human-animal studies, the thesis adopts an ethnographic approach, and seeks to develop theories of practical knowledge in the practice of teaching riding.

5. Human-Human and Human-Animal Interaction : Some Common Physiological and Psychological Effects
Sammanfattning : The aim of the present thesis was to investigate hormonal and physiological effects in mothers during a breastfeeding session and in dogs and their owners in response to short-term interaction. In study one, sixty-six mothers receiving either exogenous oxytocin infusion and/or epidural analgesia (EDA) during labor or intramuscular oxytocin injection post partum were studied. LÄS MER
