(2021)The mammalian apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like 3 (APOBEC3 or A3) family of cytidine deaminases restrict viral infections by mutating viral DNA and impeding reverse transcription. To overcome this antiviral activity, most ... -
Magma fragmentation and tephra dispersal in explosive eruptions: The 1991 and 1845 Hekla eruptions (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2017-07-12)Iceland is one of the most volcanically active terrestrial regions on Earth. Hazards posed from volcanic eruptions to local population and life stock is well known in Iceland and the wider effects from volcanic activity have been elevated in recent ...

(Springer Nature, 2017-01-25)Quartz is a common phase in high-silica igneous rocks and is resistant to post-eruptive alteration, thus offering a reliable record of magmatic processes in silicic magma systems. Here we employ the 75 ka Toba super-eruption as a case study to show ...
-
(Elsevier BV, 2018-07)How a volcano has behaved throughout its past is a guide to its future behaviour. Detailed knowledge of what preceded eruptions from specific volcanoes, and how this can be recognised in real-time, are pivotal questions of this field. Here, the physical ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2021-10)In this study, the magmatic evolution and the eruptive history of the Paka volcanic complex are investigated and its geothermal reservoir is assessed. The study comprises two parts. The first part deals with the eruptive history, magma evolution, and ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2021-01)The extent of compositional and lithological heterogeneity in Earth’s convecting mantle, caused by the recycling of oceanic and continental lithosphere, has long been a subject of interest to geochemists and geophysicists. A fundamental outstanding ...
-
(Faculty of Science and Technology of Århus University, 2019-11)This thesis covers experimental work conducted within two distinct fields of cold-atom physics. The first part describes an experiment capable of spatially-selective dispersive measurements of a cold-atomic system in part or in whole, by virtue of a ...
-
(2023-04-28)Magnetoresistance oscillations, also known as Shubnikov-de Haas (SdH) oscil- lations, is a well-known phenomena that results from the quantization of electron orbits in the presence of a magnetic field. These oscillations have been extensively studied ...
-
(Frontiers Media SA, 2020-06-05)The Negev Desert in southern Israel hosts a number of late Cenozoic lacustrine and palustrine sedimentary sequences that attest for past wetter conditions in what today constitutes one of the driest deserts on Earth. These sequences are of special ...
-
(2024)The mixed evidence of the association between high levels of cardiovascular risk factors (CVRF) and the risk for cognitive impairment may be due to confounding of age across studies. We pooled and harmonized individual-level data (30,967 persons, age ...
-
(2021)The aim of the study was to focus on whether visual processing differs between distinct levels of reading competence in young adults, from a regular orthography. We compared the 10% highest scoring (HRC) and the 10% lowest scoring groups (LRC) of reading ...
-
(2021-09-26)Despite the negative implications for their own health, spouses continue to support each other and maintain their couplehood for as long as possible, including when one of them develops a severe illness. However, with some exceptions, the experiences ...
-
(University of Iceland, School of Health Sciences, Faculty of Medicine, 2023-01-06)Injuries involving major arteries and the thorax are major causes of mortality and morbidity worldwide. Studies on the epidemiology of vascular trauma are scarce and preventive measures are of utmost importance, such as improved roads and safer vehicles. ...
-
(2022-10-07)Majorana zero modes have recently been proposed as a solution to obtain fault-tolerant quantum computation. They are quasiparticle excitations in quantum systems at the nanoscale with the potential to function as qubits, the basic building blocks of ...
-
(2022-12)Background Older people have been identified as having lower health literacy (HL) than the general population average. Living in sparsely populated Arctic regions involves unique health challenges that may influence HL. The research aim was to explore ...
-
(MDPI AG, 2020-01-31)Since the global Sustainable Development Goals (SDGs) were adopted in 2015, efforts are underway to identify indicators for monitoring progress. However, perceptions of sustainability are scale and place specific, and there has also been a call for ...
-
(MDPI AG, 2020-08-15)Nowadays, advancements in the oncology sector regarding diagnosis methods allow us to specifically detect an increased number of cancer patients, some of them in incipient stages. However, one of the main issues consists of the invasive character of ...
-
(2023-03-01)OBJECTIVE: Nail psoriasis is common, impairs fine motor finger functioning, affects cosmesis, and is associated with a lower quality of life. This review updates the previous Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) ...
-
(2022-09-01)Objective: In 2010, a questionnaire-based study on obstructive sleep apnea (OSA) management in Europe identified differences regarding reimbursement, sleep specialist qualification, and titration procedures. Now, 10 years later, a follow-up study was ...
-
(University of Iceland, School of Social Sciences, Faculty of Sociology, Anthropology and Folkloristics, 2022)Climate change is contributing to shifts in the magnitude and scale of hazards, and the emergence of environmental risks in areas where they were previously unknown. In the Öræfi district of south-east Iceland, a fracture discovered by farmers gathering ...
