21. Stewardship in an urban world : Civic engagement and human–nature relations in the Anthropocene
Sammanfattning : Never before have humans wielded a greater ability to alter and disrupt planetary processes. Our impact is becoming so noticeable that a new geological epoch has been proposed – the Anthropocene – in which Earth systems might no longer maintain the stable and predictable conditions of the past 12 millennia.

22. Urban environmental stewardship : Roles and reasons for civic engagements in governance of social-ecological systems
Sammanfattning : Stewardship as a concept is increasingly brought forward as a goal to reach sustainability goals of ensuring human wellbeing within the limits of Earth’s life support systems. Scholarship on the required capacities for planetary stewardship is growing rapidly, as are the insights. LÄS MER
23. The fate and effect of pharmaceuticals in boreal surface waters
Sammanfattning : Traces of pharmaceuticals are often found in streams, rivers, and lakes as the result of effluent water discharge. This dissertation aims to create a better understanding of the fate of drugs in aquatic ecosystems and how oxazepam, an anxiolytic pharmaceutical commonly detected in surface waters, affects the behavior of perch (Perca fluviatilis).

24. On the thermal inertia and time constant of single-family houses
Sammanfattning : Since the nineteen-seventies, electricity has become a common heating source in Swedish single-family houses. About one million smallhouses can use electricity for heating, about 600.000 have electricity as the only heating source. LÄS MER
25. Improved techniques for CE-MALDI-MS off-line coupling and MALDI-MS analysis of primarily hydrophobic proteins and peptides
Sammanfattning : Due to the hydrophobic nature of integral membrane proteins (IMP) they give rise to several difficulties concerning handling and analysis, which is not the case for the most water soluble proteins. New analysis methods are needed, where the insolubility problems of the hydrophobic proteins due to aggregation and adhesion are tackled. LÄS MER
