  • 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. ...
  • Bédi, Branislav (Háskóli Íslands, Hugvísindasvið, Mála- og menningardeild, 2020-10-26)
    Þessi doktorsritgerð er hluti af verkefninu Icelandic Language and Culture Training in Virtual Reykjavik, þrívíddartölvuleik sem gerir þeim sem eru að læra íslensku sem annað mál kleift að æfa tal og hlustun. Markmið verkefnisins var að búa til ...
  • Parsons, Katelin Marit (University of Iceland, School of Humanities, Faculty of Icelandic and Comparative Cultural Studies, 2020-11)
    Guðmundur Erlendsson of Fell in Sléttuhlíð (c. 1595–1670) was one of the leading poets of seventeenth-century Iceland. No man is an island, however, nor are islands populated exclusively by men. The thesis examines how Guðmundur Erlendsson’s poetry and ...
  • Welling, Johannes (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-10)
    Climate change constitutes one of the most pressing challenges faced by tourism today. Tourism research on climate-induced environmental changes has contributed to an increase in knowledge about adaptation during the last decade. Despite a general ...
  • Sigurðsson, Magnús (Háskóli Íslands, Hugvísindasvið, Íslensku- og menningardeild, 2019-09)
    Rannsóknin fjallar um bandaríska ljóðskáldið Emily Dickinson (1830–1886), með áherslu á túlkun og viðtökur ljóða hennar á síðari tímum, bæði erlendis sem og á Íslandi. Ritgerðin er þverfræðileg, á mörkum bókmenntafræði, þýðingafræði og ritlistar. ...
  • Magnúsdóttir, Hildur (Háskóli Íslands, 2020-10)
    Variation in morphology of shelled marine gastropods across small spatial scales may reflect restricted population connectivity, resulting in evolutionary or plastic responses to environmental heterogeneity. Species delimitation of shelled gastropods ...
  • Danielsen, Rannvá (University of Iceland, School of Social Sciences, Faculty of Business Administration, 2020-10)
    Flestir fiskistofnar heims eru nýttir að fullu eða ofveiddir. Ofnýting hefur í för með sér slæmar vistfræðilegar, hagrænar og félagslegar afleiðingar. Minna er hægt að veiða úr ofveiddum stofnum og hætta getur verið á hruni þeirra. Og af því að þeir ...
  • Gudmundsdottir, Ragnhildur (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-10)
    Crangonyx islandicus is a groundwater amphipod endemic to Iceland. Genetic analysis suggests that the species has been diverging in Iceland for at least 4.8 Myrs indicating it has survived in a subglacial refugia as Iceland was repeatedly covered by ...
  • Kreiling, Agnes-Katharina (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-10)
    Freshwater springs are thermally stable environments which are largely unaffected by changes in air temperature. They could thus have the potential to buffer rising temperatures and serve as small-scale refugia for aquatic invertebrates in a warming ...
  • Schneiderbauer, Lukas (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-09)
    This thesis discusses two aspects of semi-classical black holes. First, a recently improved semi-classical formula for the entanglement entropy of black hole radiation is examined. This entropy is an indicator of information loss and determines ...
  • Runólfsdóttir, Hrafnhildur Linnet (University of Iceland, School of Health Sciences, Faculty of Medicine, 2020-08-21)
    Adenine phosphoribosyltransferase (APRT) deficiency is a rare autosomal recessive disorder of adenine metabolism that results in the generation and renal excretion of large amounts of the poorly soluble 2,8-dihydroxyadenine (DHA), causing kidney ...
  • Óskarsson, Kristinn Ragnar (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-10)
    Life on earth is found everywhere where water is found, meaning that life has adapted to extremely varied environments. Thus, protein structures must adapt to a myriad of environmental stressors while maintaining their functional forms. In the case ...
  • Kristinsdóttir, Kristjana (Háskóli Íslands, Hugvísindasvið, Sagnfræði- og heimspekideild, 2020-09-08)
    Ísland var lén í Danmörku. Rekstur þess og stjórnsýsla var sambærileg við önnur lén innan danska ríkisins. Vestmannaeyjar voru ekki hluti af léninu Íslandi. Í rannsókninni er leitast við að sýna fram á hver staða Íslands var innan danska ríkisins og ...
