  1. 1. Submerged macrophytes in shallow eutrophic lakes - regulating factors and ecosystem effects

    Författare :John A Strand; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; marine biology; Hydrobiology; plasticity; seed banks; periphyton; grazing; alternative stable state; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : In this thesis I have studied factors that regulate submerged macrophyte abundance, morphology and distribution in shallow eutrophic lakes, and how submerged macrophytes may affect the ecosystem. Light attenuation through the water column (turbidity and water depth) is probably not the most important factor regulating the distribution of submerged vegetation in macrophyte dominated shallow eutrophic lakes, e.

    Sammanfattning : Cellular functions are governed by intricate chains of interactions between proteins. In order to properly understand cellular biology one must look into, not only protein function, but also its interacting network. LÄS MER

  4. 3. Involvement of Homologous Recombination in Response to Different Qualities of DNA Damage

    Författare :Gunilla Olsson; Mats Harms-Ringdahl; John Thacker; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; Toxikologi;

    Sammanfattning : The present studies aimed at elucidate the role of homologous recombination (HR) for the repair of different qualities of DNA damages and/or changes in chromatin structure induced by a variety of radiation qualities.Radiation qualities used to expose cells in culture ranged from non-ionizing radiation with extremely low frequency (ELF), of energies too low to disrupt chemical or molecular bonds, to radiation qualities with energies able to induce ionizations and break chemical bonds.

  5. 4. Teologi som kritik : Graham Ward och den postsekulära hermeneutiken

    Författare :Peter Carlsson; Ola Sigurdson; Håkan Möller; Jayne Svenungsson; Göteborgs universitet; []

    Sammanfattning : The British theologian Graham Ward has since the 1990 ́s been one of the most prominent voices in the theological discussions of the Anglo-American cultural sphere. As one of the key figures in the academic field that has been known as “post secularism”, “the resurgence of religion” or “the new visibility of religion” Ward has developed an independent theological position that most properly could be described as a Christian cultural critique.
