  1. 1. Effects of herbivory on arctic and alpine vegetation

    Författare :Åsa Lindgren; Ove Eriksson; Jon Moen; Anders Angerbjörn; Ingibjörg S Jónsdóttir; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; herbivory; reindeer; rodents; functional traits; plant species composition; arctic; alpine; tundra; seed limitation; Carex bigelowii; Biology; Biologi; Plant Ecology; växtekologi;

    Sammanfattning : The distribution of plant species and functional traits in alpine and arctic environments are determined by abiotic conditions, but also by biotic interactions. In this thesis, I investigate interactions among plants and herbivory effects on plant community composition and plant functional traits in three different regions: Swedish Lapland, Beringia (USA/Russia) and Finnmark (Norway).

  3. 2. Oral microbiota in relation to host traits, environment, and dental caries

    Författare :Linda Eriksson; Pernilla Lif Holgerson; Ingegerd Johansson; Anders Esberg; Peter Lingström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental caries; NGS; S. mutans; sugar; sweet; diet; taste preference; adolescents; allele variation; SLC2A4; microbiota; saliva; tooth biofilm; kariologi; Cariology;

    Sammanfattning : Background: Dental caries still appears at high prevalence worldwide. Disease distribution is skewed with more disease in socio-economically weak groups. However, also in populations considered as “low caries” there is a significant fraction with continuous disease development. LÄS MER

  4. 3. Nonlinear Dynamics and Condensed States with Broken Symmetries

    Författare :Anders B. Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns two topics where symmetry and strong correlations in time and space are important. The first topic is the theory of dynamical systems, and this theory deals with generic phenomena which are often convenient to study in very simple models. LÄS MER

  5. 4. "Nästan som en författare" - multimedialt berättande : Utforskande av lärande om och i berättande med inspiration från Vygotskij

    Sammanfattning : This thesis builds on an interest in teaching that enables learning for all children, including children with disabilities. The work is founded in a theoretical perspective on teaching and learning and respectively research practices based on Lev S. LÄS MER

  7. 5. Positron Emission Tomography in the Management of Neuroendocrine Tumors

    Författare :Håkan Örlefors; Barbro Eriksson; Mats Bergstrom; Anders Sundin; Karel Pacak; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Neuroendocrine tumor NET ; carcinoid; endocrine pancreatic tumor EPT ; Positron Emission Tomography PET ; serotonin-precursor; 5-hydroxytrytophan 5-HTP ; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Medicin; Medicine;

    Sammanfattning : Neuroendocrine tumors (NET´s) are often characterized by overproduction of peptide hormones. In spite of pronounced clinical symptoms, the tumor lesions can be small and difficult to detect. LÄS MER
