1. Communication of life cycle assessment results : life cycle key performance indicators
Abstract : The global warming that we are on track for will result in a severe loss of natural capital leading to significant losses in economic capital when urban infrastructure is destroyed, agricultural productivity declines and poverty spread among other disasters. Climate change due to emissions does not only affect the polluter, the hazardous effects becomes evident on a global level. READ MORE

2. Migratory behaviour of Baltic salmon (Salmo salar L.) : adaptive significance of annual cycles
Abstract : This thesis evaluates the adaptive significance of annual cycles on the migratory behaviour of Baltic salmon (Salmo salar L.). The studies have included field experiments as well as laboratory studies gf maturity and migratory behaviour patterns of smolts and postsmolts mainly from the Angerman river population. READ MORE

3. Thermodynamic Cycles using Carbon Dioxide as Working Fluid : CO2 transcritical power cycle study
Abstract : The interest in utilizing the energy in low‐grade heat sources and waste heat is increasing. There is an abundance of such heat sources, but their utilization today is insufficient, mainly due to the limitations of the conventional power cycles in such applications, such as low efficiency, bulky size or moisture at the expansion outlet (e.g. READ MORE

These consistent intra-specific differences in animals have been considered very important because they are often inherited, and thus, provide the basic material for evolution to act on. READ MORE

5. Molecular Regulation of the Annual Growth Cycle in Populus Trees
Abstract : Adaptation to the change of seasons is essential for tree survival. Here I show that the phenology of hybrid aspen is regulated by three FLOWERING LOCUS T (FT) genes.FT1, FT2a and FT2b are the result of both a whole genome and a local duplication. READ MORE
