1. Study of Non-metallic Inclusion in Alloy 825
Sammanfattning : It is well known that inclusions affect the properties of steels and alloys. Therefore, it is important to understand what type of inclusions that exist and how they behave and especially with a focus on large size inclusions. LÄS MER
2. Uptake and bioaccumulation of ionizable pharmaceuticals in aquatic organisms
Sammanfattning : Pharmaceuticals are found at low concentrations (ng/L) in aquatic environments but bioaccumulation may result in aquatic organisms reaching internal effect levels (µg/L). Environmental hazard assessments include standardized bioaccumulation tests but contrary to the model substances around which the frameworks are built most pharmaceuticals are designed to mimic endogenic chemicals, ionizable, and less lipophilic.

3. Models of Electoral Competition : Three Essays on Political Economics
Sammanfattning : This thesis consists of three essays in theoretical political economics. In "The Swing Voters' Blessing", I model elections with quality differences between two ideological candidates. The quality differences are only observable to a limited number of informed voters. LÄS MER
4. Bacterial Activity and Community Composition in the Rhizosphere. Influence of plant species, root age, nitrogen addition and mycorrhizal status
Sammanfattning : Microbial activity in soil is generally assumed to be limited by carbon availability. The soil closest to roots, the rhizosphere, is therefore a zone of high microbial activity due to carbon containing substances released by the root. In this work short-term effects in the rhizosphere have been the subject of investigation. LÄS MER
5. Digital Baseband Modeling and Correction of Radio Frequency Power Amplifiers
Sammanfattning : Aspects related to behavioral modeling and correction of distortions for radio frequency (RF) power amplifiers (PAs) are treated in the thesis. When evaluating the performance of a behavioral model it is important to, first of all, use an evaluation criterion, and second, make sure that the criterion actually tells something about the behavior one wishes to describe.
