(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. ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2021-05)Notkun verndarhópa á virka hópa aminosýra í litlum peptíðum gefur tækifæri til að breyta girðieiginleikum viðkomandi peptíðs við málmjónir. Alkýlun á karboxýlhóp C-enda peptíðsins beinir girðingu málmjónarinnar í fjórgirta κ4[NH2,N,N,=O] komplexa. Með ...
-
(University of Iceland, School of Health Sciences, Faculty of Medicine, 2016-12)Studying human metabolism is crucial for the understanding of diseases and improvement of therapy as metabolic alterations are central to a number of human diseases. A variety of experimental disciplines, such as biochemistry, biophysics and systems ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-06)Increasing water temperatures are predicted worldwide, with high amplitudes in the Arctic and sub-Arctic regions exceeding predictions for other regions. An understanding how Atlantic cod (<i>Gadus morhua<i>) reacted to changing environmental conditions ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-11)Microscopic magnetic particles can be found in a wide range of systems, from asteroids in outer space and minerals in the Earth’s crust to living organisms on land and in the ocean. Often they determine critical functional properties of these systems ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2021-02)The physico-chemical properties of magma storage reservoirs in multi-level magmatic systems may change with time, along with the timescales at which crystals and melts are processed throughout the crust. In this thesis, I use an integrated approach ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2021-09)Oxytocin is a uterotonic neuropeptide. It has been recommended by the World Health Organization (WHO) as the first line treatment to prevent and treat postpartum hemorrhage (PPH). PPH is the main cause of maternal deaths (27.1%) in many low-income ...
-
(University of Iceland, School of Social Sciences, Faculty of Sociology, Anthropology and Folkloristics, 2019-08-16)Gender disparity in business leadership positions has received increasing attention in the world. Globally, women are still vastly underrepresented in the higher levels of organisations. Despite women representing half of the capable work force ...
