  1. 1. Effects of Dark Matter in Astrophysical Systems

    Författare :Stefan Clementz; Mattias Blennow; Tommy Ohlsson; Riccardo Catena; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; Self-interactions; solar capture; helioseismology; inelastic dark matter; direct detection; indirect detection; Fysik; Physics;

    Sammanfattning : When studying astrophysical structures with sizes ranging from dwarf galaxies to galaxy clusters, it becomes clear that there are vast amounts of unobservable gravitating mass. A compelling hypothesis is that this missing mass, which we call dark matter, consists of elementary particles that can be described in the same manner as those of the standard model of particle physics.

  3. 2. Studies of dark matter annihilation and production in the Universe

    Författare :Carl Niblaeus; Joakim Edsjö; Riccardo Catena; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dark matter; neutrinos; astroparticle physics; indirect detection; teoretisk fysik; Theoretical Physics;

    Sammanfattning : In this PhD thesis we investigate various aspects of particle dark matter. The proper identification of dark matter developed during the second half of the twentieth century to become one of the biggest endeavours in modern physics and astronomy. LÄS MER

  4. 3. The Scholia by Hesychius of Jerusalem on the Minor Prophets : Edited with an Introduction by Mats Eriksson

    Författare :Mats Eriksson; Denis Searby; Timothy Janz; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Hesychius of Jerusalem; scholia; catena; Hexapla; biblical commentary; patristics; Grekiska; Greek;

    Sammanfattning : This dissertation contains an edition of the scholia by Hesychius of Jerusalem (died probably after 451) on the Minor Prophets of the Old Testament (CPG 6558). Apart from a few fragments, this text has never been edited before. It consists of 2 160 mostly quite brief pieces of text interpreting various aspects of the bible text. LÄS MER

  5. 4. Hydrological aspects of the carbon balance in a boreal catchment: A model study

    Författare :Alla Yurova; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cartography; pedology; geomorphology; Physical geography; boreal peatland; dissolved organic carbon; ecohydrology; model; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Sammanfattning : AbstractThe cycling of carbon in its gaseous, solid and dissolved forms is of central importance to ecosystem science, particularly, when the natural carbon cycle has been perturbed by human activity. Mathematical models are commonly used to asses and predict global and regional patterns of terrestrial carbon exchange. LÄS MER

  7. 5. On-farm agrohydrological analysis of the Sahelian yield crisis : rainfall partitioning, soil nutrients and water use efficiency of pearl millet

    Författare :Johan Rockström; Jim Wallace; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Natural Resources Management; naturresurshushållning;

    Sammanfattning : Sub-Saharan Africa is presently experiencing a steadily aggravated food security crisis. This crisis is a result of a rapidly growing population combined with insignificant yield increases of the major cereal crops maize, millet and sorghum, during the last decades. LÄS MER
