(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2019-09-02)An active field of research in magnetism today involves studies of solitons -- localised magnetic textures possessing particle-like properties. They are considered promising for various applications but are also intriguing from a fundamental point of ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-06)Electron paramagnetic resonance (EPR) spectroscopy is routinely used to study the structure and dynamics of nucleic acids, to obtain information about their functions. A prerequisite for most EPR studies of nucleic acids is the incorporation of ...

(Háskóli Íslands, Hugvísindasvið, Guðfræði- og trúarbragðafræðideild, 2014-03-26)Lord’s Supper in Iceland 1570-1720. Procedure and Impact The Lord’s Supper in Iceland in the period from 1570 to 1720 is the core focus of this thesis. Limited research has been undertaken on this topic, despite its significance for a greater understanding ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-05-31)The protein and amino acid metabolism of thermophilic bacteria has been a neglected aspect of their physiology despite its biotechnological potential. Under anaerobic conditions, the metabolism of many proteogenic amino acids requires the presence of ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Civil and Environmental Engineering, 2018-11-23)A comprehensive site-effect investigation framework was developed and applied to earthquake strong-motion data collected on small-aperture urban arrays, the ICEARRAY I in Hveragerði in the South Iceland Seismic Zone and ICEARRAY II in Húsavík in the ...
-
(University of Iceland, School of Health Sciences, Faculty of Medicine, 2018-09-21)The geographic remoteness of the Faroe Islands makes the archipelago an ideal location for research on bacterial carriage, their clonality, and vaccine studies. However, previous studies are lacking and the limited availability of necessary data has ...
-
(University of Iceland, School of Humanities, Faculty of History and Philosophy, 2018-12-12)This thesis aims to refine the accuracy and precision of radiocarbon (14C) datasets in order to better understand the timing of archaeological and palaeoenvironmental events relating to important issues like mobility, colonisation, human impacts and ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-01-28)The geo-political importance of the Arctic is growing while at the same time the onset of climate change has resulted in increasing environmental and social pressures both on Arctic states and the governance architecture through which Arctic issues ...
