21. Trees and the environment : Possibilities and challenges in tree-ring research across spatial and temporal scales based on case studies in Sweden
Sammanfattning : The need to understand and quantify the magnitude and frequency of past and current environmental changes increased the demand for high-resolution proxy data across spatial and temporal scales. Due to their long lifespan and global distribution, trees provide a unique and continuous record of environmental variability. LÄS MER
22. Modelling District Heating Network Costs
Sammanfattning : The solution of the undergoing climate and energy crises requires a radical transformation of the energy system, in which sustainability, no carbon emissions and energy efficiency ought to play a paramount role. This revolution should extend to all areas of the energy system, including the space heating and cooling sector, which accounts for a third of the European final energy demand and, in the European continent, it is still mostly supplied by fossil fuels.

23. Unilateral Cleft Lip and Palate : Quality of Life and Nasal Form and Function among Adults
Sammanfattning : Unilateral cleft lip and palate (UCLP) is a craniofacial malformation with functional and aesthetical impact on the face and the upper airways. The aims of the current thesis were to evaluate Quality of life (QoL) in adults treated for UCLP (I), to objectively evaluate nasal form and function and to search for possible differences in residual nasal deformity and impairment of function between patients operated according to one-stage and two-stage palate closure (II) as well as to evaluate the relationship between professional and lay rating and patient satisfaction with nasolabial appearance (III) and to identify factors associated with lower levels of QoL and less satisfaction with nasal appearance among adults treated for UCLP (IV).

24. Species interactions in streams - effects of predation, competition and ecosystem properties
Sammanfattning : Stream ecosystems are dynamic and they have an inherent environmental variability. Organisms that live in streams are adapted to the continuously changing environment and the presence or absence of species are determined by their environmental requirements, while abundance is most often affected by interactions, such as competition and predation, with other species that are found in the same habitat.

25. Strategies for improving kraftliner pulp properties
Sammanfattning : A large part of the world paper manufacturing consists of production of corrugated board components, kraftliner and fluting, that are used in many different types of corrugated boxes. Because these boxes are stored and transported, they are often subjected to changes in relative humidity. LÄS MER
