  1. 1. The hidden life of plants : fine root dynamics in northern ecosystems

    Författare :Gesche Blume-Werry; Roland Jansson; Ann Milbau; Scott D. Wilson; Isla Myers-Smith; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; belowground; boreal; climate change; fine roots; heath; meadow; minirhizotron; permafrost; phenology; plant community; root biomass; root growth; root litter; root production; subarctic; tundra;

    Sammanfattning : Fine roots constitute a large part of the primary production in northern (arctic and boreal) ecosystems, and are key players in ecosystem fluxes of water, nutrients and carbon. Data on root dynamics are generally rare, especially so in northern ecosystems. LÄS MER

  5. 4. Jasmonates in root nodule development

    Författare :Anna Maria Zdyb; Katharina Pawlowski; Sofie Goormachtig; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lotus japonicus; jasmonic acid; actinorhizal; rhizobia; Frankia; root nodule; lipoxygenase; allene oxide cyclase; allene oxide synthase; Casuarina; Datisca; Medicago; Plant physiology; Växtfysiologi; växtfysiologi; Plant Physiology;

    Sammanfattning : Jasmonic acid (JA), its derivatives and its precursor form a group of phytohormones, the jasmonates, representing signal molecules involved in plant stress responses, in the defense against pathogens as well as in development. Elevated levels of JA have been shown to play a role in arbuscular mycorrhiza and in the induction of nitrogen-fixing root nodules. LÄS MER

  7. 5. Coronal restoration in root-filled and non root-filled teeth : studies on periapical status, tooth survival, subsequent treatments and treatment decisions

    Författare :Victoria Dawson; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endodontics; Coronal restoration; Indirect restoration; Direct restoration; Root canal treatment; Decision process; Apical periodontitis; Qualitative Content Analysis;

    Sammanfattning : The overall aim of this thesis was to study the following aspects ofdirect and indirect coronal restoration, primarily of root-filled teeth, withspecial reference to:• periapical health• the natural course of root-filled teeth, particularly furtherclinical intervention• the dentist´s decision-making process for root-filled teeth.The aims of coronal restoration are to restore the function and aestheticsof the tooth, with a tight marginal seal as protection from microbialleakage.
