  • Bohr, Sebastian (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2021-07)
    The nature of dark matter (DM) as a particle is still an unresolved mystery in Physics. Therefore, a vast amount of competing particle models have been proposed. A promising category among these models are those that include relevant collisional damping ...
  • Juncu, Daniel (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2018-01)
    Deformation of geothermal reservoirs is a growing topic in the field of crustal deformation research. The deformation behavior of a geothermal resource can give us insight about its sustainability and can help to increase our understanding of reservoir ...
  • Konchak, William (University of Iceland, School of Humanities, Faculty of History and Philosophy, 2018-11)
    This dissertation draws upon philosopher Pierre Hadot’s conception of philosophy as a way of life, which views philosophy as a process of self-transformation through engaging in practices (which Hadot characterizes as spiritual exercises) alongside ...
  • Jónsdóttir, Sigríður (University of Iceland, School of Health Sciences, Faculty of Medicine, 2017-03)
    Insect bite hypersensitivity (IBH) is a type I allergy of horses with production of IgE and release of inflammatory mediators. It is caused by bites of midges of the genus Culicoides. The disease is a recurrent dermatitis characterized by pruritic skin ...
  • Ólafsdóttir, Inga María (University of Iceland, School of Health Sciences, Faculty of Psychology, 2020-11)
    Visual attention has traditionally been studied with single-target search tasks where observers look for a single target and make a response, then the search is over and the trial ends. These studies have furthered our knowledge of visual attention ...
  • Armesto Jimenez, Amaranta (University of Iceland, School of Health Sciences, Faculty of Medicine, 2018-08-17)
    Idiopathic pulmonary fibrosis is a severe lung disease with unknown aetiology. The lifespan is approximately 3 to 5 years after diagnosis, and the treatments available such as lung transplant are high risk and are not suitable for all patients. In ...
  • Brynjólfsson, Skafti (Norwegian University of Science and Technology; University of Iceland, 2015-09)
    This thesis describes the glacial history, glacier dynamics, sediments and landforms of the Drangajökull ice cap as well as the glacial history and dynamics of the eastern Vestfirðir peninsula in northwest Iceland from the Late Weichselian until present. ...
  • Larranaga, Nicolas (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2016-11)
    Diel activity, the partitioning of time between periods of activity and rest, gives insights into how organisms compete for resources in time. Some species show plasticity in the rate and timing of their activity, which enables to study associations ...
  • Nyamweya, Chrispine (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-01)
    Lake Victoria is of immense ecological and socio-economic significance for the riparian communities. However, the lake is faced with human induced pressures such as overfishing, introduction of alien species, increased eutrophication and climate change ...
  • Silva, Teresa Sofia Giesta da (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2018-12-14)
    Krill are an important component of the Icelandic marine ecosystem. Given their important ecological niche, as conveyors of biological production between phytoplankton and higher trophic levels, fluctuations in krill abundance can have large impacts ...
  • Malinauskaite, Laura (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-06)
    The thesis examines the dynamics of Arctic social-ecological systems (SES) that enable human wellbeing benefits through whale ecosystem services (ES). It does so through a review of relevant literature, construction of conceptual models, two primary ...
  • Eysteinsdóttir, Jenna Huld (University of Iceland, School of Health Sciences, Faculty of Medicine, 2017-12-08)
    Abstract Psoriasis is a chronic immune-mediated inflammatory skin disease with profound effects on psychosocial wellbeing. Narrowband UVB phototherapy is a known effective treatment for chronic plaque psoriasis and previous studies suggest an ...
  • Myszor, Iwona Teresa (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-02)
    Innate immunity of the lung epithelium provides efficient defenses against pathogens or other stress factors by secretion of antimicrobial peptides, presence of cellular junction proteins and autophagy. Upon activation through epithelial cell receptors ...
  • Kubiriza, Godfrey (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2017-06)
    Although conditions for aquaculture in Uganda and East-Africa are favourable, production remains low. One of the primary limitations to aquaculture development in the region is the lack of economical aquafeeds produced from local raw materials. In ...
  • Guðmundsdóttir, Ása Bryndís (University of Iceland, School of Health Sciences, Faculty of Medicine, 2019-06-04)
    Lækningamáttur Bláa Lónsins var uppgötvaður af sórasjúklingum skömmu eftir myndun þess og hafa jákvæð áhrif böðunar í lóninu verið staðfest í klínískum rannsóknum. Enn fremur hefur verið sýnt að böðun í lóninu samhliða UVB meðferð sé árangursríkari en ...
