    Sammanfattning : As sequencing technologies advance genome studies are becoming a basic tool for studying an organism, and with more genomes available comparative genomics is maturing into a powerful tool for biological research. This thesis demonstrates the strength of a comparative genomics approach on a group of understudied eukaryotes, the diplomonads. LÄS MER

  4. 3. Evaluation of Biomarker Responses in Fish : with Special Emphasis on Gill EROD Activity

    Sammanfattning : Many chemicals present in the aquatic environment can interfere with physiological functions in fish. Exposure to chemicals can be revealed by the use of biomarkers. Induction of 7-ethoxyresorufin O-deethylase (EROD) activity is a commonly used biomarker for exposure to CYP1A inducers such as dioxins and polyaromatic hyrdrocarbons. LÄS MER

    Sammanfattning : The aim of this thesis is to analyze the establishment and development of lectureships in the Swedish language in German universities during the first half of the 20th century. Building on earlier research about the role of language teaching abroad for public diplomacy, the study sees the lecturer as a part of both the the academic and political fields in Germany and Sweden.
