  • Ottelin, Juudit (Unigrafia, Helsinki, 2016-11)
    Climate change mitigation in the built environment encompasses various mitigation measures, such as energy efficient buildings, spatial planning instruments and other policies targeting the emissions resulting from transport. However, studies on the ...
  • Harning, David (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2019-04)
    Iceland’s position at the confluence of major oceanic and atmospheric fronts results in a highly sensitive climate evident in both instrumental and paleo records. However, open questions still remain regarding the pre-instrumental evolution of climate, ...

    The Lisbon Treaty grants permission to each European Union Member to determine which energy sources shall be used to supply its electricity. While EU members may act independently in this regard, since 1996 when Directive 96/92/EC went into effect, ...
  • Eliasdottir, Thorunn (University of Iceland, School of Health Sciences, Faculty of Nursing, 2017-06)
    Purpose: Continuous peripheral pulse oximetry for monitoring adequacy of oxygenation is probably the most important technological advance for patients’ monitoring and safety in the last decades. Pulse oximetry has the disadvantage of measuring the ...
  • Leifsson, Rúnar (University of Iceland, School of Humanities, Faculty of History and Philosophy, 2018-05)
    In this thesis the ritual killing and burial of animals on grave-fields in Viking Age Iceland is critically re-evaluated, on a site-by-site basis, in order to characterize these customs and place them in a social and historical context. The foundation ...
  • Oddsdóttir, Rannveig (Háskóli Íslands, Menntavísindasvið, Kennaradeild., 2018-02-09)
    Textaritun er flókið viðfangsefni sem tekur langan tíma að ná góðum tökum á. Börn byrja ung að prófa sig áfram með ritað mál og nýta sér teikningar og tákn til að koma hugsun sinni til skila. Smám saman átta þau sig á uppbyggingu ritmáls og fara að ...
  • Remina, Dilixiati (University of Iceland, School of Health Sciences, Faculty of Medicine, 2019-03)
    The pigment producing melanocytes are derived from the neural crest cells and form precursor cells called melanoblasts. These cells proliferate and migrate to their destination in skin, hair and other organs where they differentiate into melanocytes ...
  • Götz, Markus (University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2017-12-05)
    Á síðastliðnum áratug hefur orðið mikil aukning í framleiðslu og geymslu gagna í iðnaði sem og rannsóknum. Þrátt fyrir að gagnagreining sé ekki ný af nálinni, stendur hún frammi fyrir þeirri áskorun að ráða við síaukið magn, bandvídd og flækjustig ...
  • Stefánsson, Kristján K. (Univeristy of Iceland, 2017-05)
    The importance of school engagement (i.e., the willingness to engage in learning) for school success, such as good academic achievement and low dropout rates, has been well established. At the same time, intentional selfregulation (ISR; i.e., the ...
  • Di, Xiaxia (University of Iceland, School of Health Sciences, Faculty of Pharmaceutical Sciences, 2019-01-07)
    A substantial diversity of secondary metabolites from marine invertebrates has been described; however, only a few studies have investigated secondary metabolites of marine invertebrates collected in Icelandic waters. The unique marine environment ...
  • Quirk, Sigríður Júlía (University of Iceland, School of Health Sciences, Faculty of Medicine, 2019-04)
    The pneumococcus is a major human pathogen that causes morbidity and mortality worldwide. Pneumococci are normally carried asymptomatically in the nasopharynx of healthy pre-school children. Pneumococcal infections can range from acute otitis media ...
  • Schmidt, Louise Steffensen (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2019)
    This dissertation describes the research results from applying regional climate models (RCMs) to simulate the near-past and future evolution of Vatnajökull, the largest ice cap in Iceland, and investigate the sensitivity of ablation to albedo and spring ...
  • Magnúsdóttir, Edda (Faculty of Life and Environmental Science, University of Iceland, 2017-05-19)
    The cyclically-repeated song of the male humpback whale (Megaptera novaeangliae) is an important social display on their breeding grounds, functioning in male-male interactions and/or as a reproductive display to attract females. The songs are gradually ...
  • Óladóttir, Hanna (Háskóli Íslands, Hugvísindasvið, Íslensku- og menningardeild, 2017-09-08)
    Í rannsókninni er sjónum beint að þeim hugmyndafræðilega grunni sem málfræðikennsla í grunnskólum á Íslandi, skólamálfræðin, byggist á til að leggja til umræðunnar um hvað eigi að kenna í málfræði og hvers vegna. Gengið er út frá að nemendur þurfi ...
