(Bergur Einarsson, 2018-05-23)Continuous GPS measurements on three broad and gently sloping temperate ice-cap outlets in southern and western Vatnajökull, southeast Iceland, and in northern Hofsjökull, central Iceland, are the subject of this thesis. The measurements show events ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2017-12-18)Thermal anomalies are observed at many volcanoes, resulting from geothermal and magmatic activity, and are usually difficult to quantify since the measurement of heat fluxes from the ground to the atmosphere is subject to large uncertainties. However, ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2023-03)The chemical interaction between seawater and basalt at low temperatures (≤150°C) ranks among the more significant factors controlling the composition of seawater and the oceanic crust. However, the time-integrated geochemical and petrographic outcomes ...
-
(University of Iceland, School of Health Sciences, Faculty of Medicine, 2021-09-24)Inngangur: Langvinnt eitilfrumuhvítblæði (CLL) er sjúkdómur sem leggst helst á eldra fólk, meðalaldur þeirra sem greinast er um 72 ár. Langt fram eftir 20. öldinni var helsta meðferðin við sjúkdómnum chlorambucil, en í kringum aldamót breyttist ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2019-08-27)Dust is an important component of the earth-atmosphere system, affecting amongst other things air quality, vegetation, infrastructure, animal and human health. Iceland produces a large amount of dust, with dust storms reported frequently especially ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-12)A holistic understanding of the underlying dynamics of sustainable energy system development and its effects on socio-economic and environmental aspects, in different national contexts, is necessary for improved decision making with regards to sustainable ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2019-06-11)Steelmakers should consider diverting capital to the end-of-life services that promote circularity as a new strategy towards resource ownership retention and raw material selfsufficiency. These hold the key to curbing steel supply concerns in the ...

(2021-09)To gain information about the function of nucleic acids, their structure and dynamics need to be investigated. Electron paramagnetic resonance (EPR)- and fluorescence spectroscopies are highly sensitive and valuable techniques to study nucleic acids. ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2023-05)Methoxylated ether lipids (MELs) are a subset of 1-O-alkyl-sn-glycerols that are found ubiquitously in nature in very low concentrations. The MELs occur in significantly higher amounts in the liver oil of shark and related cartilaginous fish species. ...
