  1. 6. 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. 7. A View on the Invisible : A Study of Relationships between Different Aspects of Health in Populations

    Författare :Aija Duntava; Ilkka Henrik Mäkinen; Hannah Bradby; Susanne Kelfve; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; morbidity; functional limitation; subjective health; mortality; health; aspects of health; adult population; Europe; structural equation modelling; regional comparisons; health structure; systematic review; empirical studies; Sociologi; Sociology;

    Sammanfattning : This thesis studies relationships between different aspects of health. Health is a multi-faceted concept consisting of various aspects: most commonly morbidity, functional limitation, subjective health, and mortality. LÄS MER

  4. 8. Plant colonization of oak plantations - the interactive effects of local environment and land-use history

    Författare :Karin Valtinat; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nitrogen mineralization; Phosphorus; Plant ecology; Växtekologi; Soil acidity; Seed sowing; Dispersal limitation; Species diversity; Indicator species analysis; Functional groups; Succession; Understory vegetation; Land-use history; Temperate forest;

    Sammanfattning : In Europe, only small fragments of deciduous woodlands remain intact and species dependent on this ecosystem have declined. In southern Sweden, a shifting trend during the 20th century, with more afforestations on former arable land, resulted in new oak stands. These new stand are either on former arable fields or on continuously forested land. LÄS MER

  5. 9. Egressibility : Applying the concept of accessibility to the self-evacuation of people with functional limitations

    Författare :Erik Smedberg; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evacuation; Egress; Egressibility; Disability; Accessibility; Impairment; Functional limitations;

    Sammanfattning : The population is getting increasingly older, and old age is correlated with decreased functional capacity. In society, continuous improvements in accessibility of public environments is apparent. LÄS MER

  7. 10. First Principles Studies of Functional Materials Based on Graphene and Organometallics

    Författare :Sumanta Bhandary; Biplab Sanyal; Olle Eriksson; Stefano Sanvito; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphene; Magnetism; Organometallics; Density functional theory; Electron correlation; Spin switching; Nanoribbons; Exchange interaction; Edge functionalization; Band gap; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : Graphene is foreseen to be the basis of future electronics owing to its ultra thin structure, extremely high charge carrier mobility,  high thermal conductivity etc., which are expected to overcome the size limitation and heat dissipation problem in silicon based transistors.
