(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-09)This thesis discusses two aspects of semi-classical black holes. First, a recently improved semi-classical formula for the entanglement entropy of black hole radiation is examined. This entropy is an indicator of information loss and determines ... -
(University of Iceland, School of Health Sciences, Faculty of Medicine, 2020-08-21)Adenine phosphoribosyltransferase (APRT) deficiency is a rare autosomal recessive disorder of adenine metabolism that results in the generation and renal excretion of large amounts of the poorly soluble 2,8-dihydroxyadenine (DHA), causing kidney ...

Relating Depth and Diversity of Bivalvia and Gastropoda in Two Contrasting Sub-Arctic Marine Regions (Frontiers Media SA, 2019-03-22)The need to understand species distribution- and biodiversity patterns in high-latitude marine regions is immediate as these marine environments are undergoing rapid environmental changes, including ocean warming and ocean acidification. By the year ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-10)Life on earth is found everywhere where water is found, meaning that life has adapted to extremely varied environments. Thus, protein structures must adapt to a myriad of environmental stressors while maintaining their functional forms. In the case ...

(Háskóli Íslands, Hugvísindasvið, SSagnfræði- og heimspekideild, 2020-09-08)Ísland var lén í Danmörku. Rekstur þess og stjórnsýsla var sambærileg við önnur lén innan danska ríkisins. Vestmannaeyjar voru ekki hluti af léninu Íslandi. Í rannsókninni er leitast við að sýna fram á hver staða Íslands var innan danska ríkisins og ...

(Frontiers Media SA, 2019-02-25)Understanding the structure of a bacterial population is essential in order to understand bacterial evolution. Estimating the core genome (those genes common to all, or nearly all, strains of a species) is a key component of such analyses. The size and ...

(University of Craiova, Department of Communication, Journalism and Education Science, Center for Scientific Research in Communication Sciences, Media and Public Opinion, 2020)In a global context marked by the need to uphold democracy and human rights, education for democratic citizenship (EDC) has increasingly emerged as a prerequisite for shaping active and responsible citizens for the decades to come. The importance ...

(MDPI AG, 2019-03-21)We theoretically consider a short quantum wire, which on both ends is connected to leads that have different temperatures. The quantum wire is assumed to be coupled to a cavity with a single-photon mode. We calculate the heat and thermoelectric currents ...

(Oxford University Press (OUP), 2019-01-09)The characterization of magnetic minerals in rocks often uses methods that measure induced magnetization. When rocks, sediments or soils contain two magnetic phases, in which one has a high saturation magnetization (MS), for example magnetite, and the ...
-
(Royal Society of Chemistry (RSC), 2019-04-22)Light-driven molecular reactions are dictated by the excited state potential energy landscape, depending critically on the location of conical intersections and intersystem crossing points between potential surfaces where non-adiabatic effects govern ...
-
(Informa UK Limited, 2019-04)Purpose: Postpartum psychosis is a rare but severe complication following childbirth, with unknown etiology. This study investigated whether the death of a close family member — a source of severe stress — the year before or during pregnancy was ...
