    • The influence of climate on ozone risk for vegetation 

      Klingberg, Jenny (2011-05-11)
      Ground-level ozone (O3) is a harmful air pollutant causing reduced crop yield and quality, reduced forest growth and negative effects on human health in large parts of the world. O3 is generally seen as a regional scale ...
    • Regulation of electron donation to photosystem 1 

      Farkas, Daniel (2011-05-09)
      Photosynthesis is the process where energy from light is used to catalyze the formation of energy-rich molecules such as NADPH and ATP. These reactions are in fact the result of a long series of electron-transfer reactions ...

    • AQUAPORINS: Production Optimization and Characterization 

      Öberg, Fredrik (2011-05-05)
      Aquaporins are water facilitating proteins embedded in the cellular membranes. Such channels have been identified in almost every living organism – including humans. They are vital molecules and their malfunction can lead ...
    • Alien Fish Species in the Eastern Mediterranean Sea: Invasion Biology in Coastal Ecosystems 

      Kalogirou, Stefan (2011-04-25)
      The spread of non-indigenous species (NIS) in the eastern Mediterranean Sea is an ongoing and accelerating process. Non-indigenous species are regularly reported from various coastal habitats in the eastern Mediterranean ...
    • Systematics of Marionina (Annelida: Clitellata: Enchytraeidae) 

      Matamoros, Lisa (2011-04-25)
      This thesis is about species of segmented worms that previously were placed in the genus Marionina Michaelsen, 1890, within the family Enchytraeidae, class Clitellata and phylum Annelida. These species are closely related ...
    • Absolute Asymmetric Synthesis 

      Lennartson, Anders (2011-04-18)
      Absolute asymmetric synthesis is the synthesis of optically active products from achiral or racemic precursors only. This has generally been regarded as impossible and is relevant in the discussion of the origins of ...
    • Environmental and health hazards of chemicals in plastic polymers and products 

      Lithner, Delilah (2011-04-15)
      Plastics are extremely diverse in terms of chemical composition, properties and possible applications, and are widely distributed in the society and the environment. In the last 15 years the global annual production has ...
    • Ädelputs 

      Grevillis Fond, Göteborgs universitet, John Hedins Stiftelse, Länsantikvarieföreningen, Mariestads kommun, Riksantikvarieämbetet, Statens fastighetsverk, Svenska kyrkan, Sveriges Hembygdsförbund, Västarvet, Västra Götalandsregionen (Hantverkslaboratoriet, Göteborgs universitet, 2011)
      Ädelputsen som introducerades under 1900-talets början hör till det moderna byggandet. Man har använt olika verktyg och hantverkstekniker, vilka präglar putsernas och arkitekturens uttryck. Man har också använt olika ...
    • Homochiral Crystals for Selective Synthesis 

      Kokoli, Theonitsa (2011-04-13)
      Six new coordination compounds were prepared from monodentate sulfide ligands and copper(I) halides and their crystal structures were determined by single-crystal X-ray diffraction. The aim was to prepare coordination polymers ...
    • The Importance of a Fifth Element in Transcription: Transcriptional Discrimination in Escherichia coli 

      Gummesson, Bertil (2011-04-08)
      Upon growth arrest of the bacterium Escherichia coli, RNA polymerase (Es70) is redirected from transcribing genes encoding the protein synthesizing system (PSS) to those involved in maintenance and stress resistance. The ...
    • Seals and fisheries: a study of the conflict and some possible solutions 

      Königson, Sara (2011-04-08)
      Interaction between seals and fisheries along the Swedish coast has serious environmental and economic consequences. This thesis describes the conflict as it affects four different small-scale coastal fisheries; the eel ...
    • Index theory in geometry and physics 

      Goffeng, Magnus (2011-04-06)
