  1. 11. Long-lasting ecological legacies of reindeer on tundra vegetation

    Författare :Dagmar D. Egelkraut; Johan Olofsson; Bruce Forbes; Hans Tømmervik; René van der Wal; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alternative stable state; Herbivory; Historical contingency; Nutrient cycling; Plant-herbivore interactions; Plant-soil feedbacks; Rangifer tarandus; Reindeer herding; Traditional land use; Tundra vegetation;

    Sammanfattning : Reindeer can have strong effects on the plant species composition and functioning of tundra ecosystems, and often promote a transition towards a graminoid-dominated vegetation type. As a result, they influence many ecological processes, such as nutrient dynamics, soil biotic composition and functioning, and carbon storage. LÄS MER

  3. 12. Antibody-based Cancer Immunotherapy : Personalization, response prediction and safety considerations

    Författare :Mohamed Eltahir; Sara Mangsbo; Patrick Micke; Gustav Ullenhag; Marit Inderberg; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : Antibody-based therapeutics have remarkably improved the field of immuno-oncology. Multiple monoclonal antibodies (mAbs) are approved for clinical use, and numerous antibodies are under clinical development. The scope of this thesis is to study the personalization of antibody-based immunotherapeutics and tools to predict their efficacy and safety. LÄS MER

  4. 13. Modeling the Lunar plasma wake

    Författare :Shahab Fatemi; Bengt Eliasson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Sammanfattning : This thesis discusses the solar wind interaction with the Moon and the formation of the lunar plasma wake from a kinetic perspective. The Moon is essentially a non-conducting body which has a tenuous atmosphere and no global magnetic fields. The solar wind plasma impacts directly the lunar day-side and is absorbed by the lunar surface. LÄS MER

  5. 14. Stripped-envelope supernovae discovered by the Palomar Transient Factory

    Författare :Christoffer Fremling; Jesper Sollerman; Federica Bianco; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supernovae; transients; Astronomy; astronomi;

    Sammanfattning : This thesis is based on research made by the intermediate Palomar Transient Factory [(i)PTF]. The focus is on stripped-envelope (SE) supernovae (SNe) discovered by (i)PTF, and it is closely tied to the research on the SE SN iPTF13bvn, that occurred in the nearby galaxy NGC 5806. LÄS MER

  7. 15. The Use of Press Archives in the Temporal and Spatial Analysis of Rainfall-Induced Landslides in Tegucigalpa, Honduras, 1980-2005

    Författare :Elias Garcia-Urquia; Kristofer Gamstedt; José Cepeda; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; press archives; landslide database; urban landslides; critical rainfall intensity; antecedent rainfall; rainfall frequency contour lines; matrix method; landslide susceptibility index; Tegucigalpa; Honduras; Hurricane Mitch; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

    Sammanfattning : The scarcity of data poses a challenging obstacle for the study of natural disasters, especially in developing countries where the social vulnerability plays as important a role as the physical vulnerability.  The work presented in this thesis is oriented towards the demonstration of the usefulness of press archives as a data source for the temporal and spatial analysis of landslides in Tegucigalpa, Honduras for the period between 1980 and 2005.
