  • Quintana Cocolina, Carmen (University of Iceland, School of Humanities, Faculty of Languages and Cultures, 2021-01)
    Spanish author C. Martín Gaite developed a number of theories on communication and the interlocutor in her essays and articles, that she put in practice in her narrative work through author-reader and characters communicative interaction. This study ...
  • Rasmussen, Maja Bar (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2021-01)
    The extent of compositional and lithological heterogeneity in Earth’s convecting mantle, caused by the recycling of oceanic and continental lithosphere, has long been a subject of interest to geochemists and geophysicists. A fundamental outstanding ...
  • Jonasson, Jonas Pall (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-01)
    The marine ecosystem around Iceland is shaped by its position in one of the most hydrographically complicated regions of the North Atlantic. The response of marine populations to those diverse conditions is expected to be different across taxonomically ...
  • 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 ...
  • Ívarsdóttir, Erna Valdís (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-11)
    The aim of genome-wide association studies (GWAS) is to identify sequence variants that influence human traits or diseases. Previous GWAS have mostly focused on finding variants that affect the mean of a trait or disease risk under an additive model. ...
  • Kalliokoski, Maarit (University of Turku; University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2020-11-13)
    Tephrochronology is a high-precision dating method that uses volcanic ash horizons as isochrons in correlating and dating geological records and archaeological sites. First developed in the volcanic regions of the world, tephrochronology has expanded ...
  • Vidarsdottir, Olina (University of Iceland, school of health sciences, faculty of medicine, 2020-09)
    Background: Cognitive impairment is a core feature at all stages of the psychotic illness and significantly predicts functional outcomes. Targeting cognition early is theoretically attractive as a means to reverse the functional impairment before ...
  • Mandal, Sucharita (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-12-15)
    Dynamic nuclear polarization (DNP) has emerged as an important technique to enhance the signal intensity of nuclear magnetic resonance (NMR) spectroscopy by transferring spin polarization from unpaired electrons to nuclei of interest. Persistent organic ...
  • Gunnarsdóttir, Ingunn (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-12)
    Sustainable energy development is a cross-cutting policy objective with the ultimate aim of a sustainable energy future. However, what that future involves and how it can be reached is unclear. The aim of this PhD thesis is to address the question ...
  • Sigurdardottir, Thorgerdur (University of Iceland, School of Health Sciences, Faculty of Medicine, 2020-12-14)
    Markmið: Meginmarkmið þessa doktorsverkefnis var að kanna tíðni grindarbotnseinkenna og vanlíðunar sem þau valda frumbyrjum á fyrstu mánuðum eftir fæðingu, ásamt því að rannsaka hvort tengsl findust milli grindarbotnseinkennanna og fæðingartengdra ...
  • Butler, William (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-12)
    The population dynamics of marine fish are driven by many top-down and bottom-up processes operating across multiple life-history stages. The majority of teleosts produce large quantities of offspring which experience high mortality rates early in ...
  • Grétarsson, Kristján Hólm (University of Iceland, School of Health Sciences, Faculty of Medicine, 2020-12)
    Umframerfðastjórnprótein taka þátt í að stjórna mismunandi genatjáningu og koma þannig up sérhæfðu umframerfðamengi í frumum sem allar hafa sama erfðamengið. Það er mikilvægt að skilja hvernig umframerfðamerkjum er stjórnað snemma í fósturþroskun ...
  • Morera, Erika (University of Iceland, School of Health Sciences, Faculty of Medicine, 2020-12-02)
    Epithelial to mesenchymal transition (EMT) is a developmental trait that is hijacked in some disease conditions such as fibrosis and cancer. In cancer, EMT has been linked to increased invasion and metastasis, and is generally associated with a poor ...
  • 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 ...
  • Gladkykh, Ganna (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-11)
    This PhD thesis explores what can be considered a sustainable energy system on a global scale and what methods and tools can help sustainable energy policy design and assessment. Energy system modelling and sustainable energy system narratives are the ...
  • Praphanwittaya, Pitsiree (University of Iceland, School of Health Sciences, Faculty of Pharmaceutical Sciences, 2020-11)
    Background: Age-related macular degeneration (AMD) causes vision loss in elderly people due to neovascularization. The first line treatments are intravitreal injections which can induce severe pain. Oral administration still produces side effects. ...
  • Rafik Hama, Susan (University of Iceland, School of Education, Faculty of Education and Diversity, 2020-11)
    The influx of refugees and immigrants into Iceland continues to affect the society socially, culturally, and politically. Like many other European countries, Iceland has become home to many refugees and immigrants, including young adults. This influx ...
  • Tayyebi, Ebrahim (University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2020-10-22)
    The main target of this thesis is to use density functional theory-based simulations to study electrochemical CO2 and N2 reductions by employing a recent theoretical model of an electrochemical solid-liquid interface. This model is used to investigate ...
  • Angel Ramelli, Juan Fernando (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-11)
    In recent years, the study of entanglement properties of quantum field theories has led to deep insights in fields as diverse as quantum gravity and condensed matter physics. Originating as effective field theories for certain quantum dimer models, the ...
  • Lorenzo Veiga, Blanca (University of Iceland, School of Health Sciences, Faculty of Pharmaceutical Sciences, 2020-10-26)
    Ocular drug delivery is very challenging due to the anatomical and physiological barriers of the eye. Poor aqueous solubility of many drugs and short retention time at ocular surfaces makes the formulation of topical dosage forms even more challenging. ...
