(Háskóli Íslands, Menntavísindasvið, 2020-03-19)Flest okkar hafa orðið áþreifanlega vör við útbreiðslu COVID-19 sýkingarinnar og samfélagslegar afleiðingar hennar. Mörg okkar finna fyrir mikilli óvissu í þessum aðstæðum og því eðlilegt að fólk á öllum aldri, ekki síst börn og ungmenni, finni fyrir ... -
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2016-12)For most of the Holocene the main driver of vegetation and environmental change in Iceland was climate, although intermittent volcanic events had short term impacts. This changed with the Norse colonisation in the late 9th century AD, from when land ...

(Elsevier BV, 2020-09)We synthesize the current understanding of glacier activity on Svalbard from the end of the Late Pleistocene (12,000 yrs. before present) to the end of the Little Ice Age (c. 1920 AD). Our glacier history is derived from the SVALHOLA database, the first ...
-
(Elsevier BV, 2020-07-15)Arctic precipitation is predicted to increase in the coming century, due to a combination of enhanced northward atmospheric moisture transport and local surface evaporation from ice-free seas. However, large model uncertainties, limited long-term ...
-
(Springer Science and Business Media LLC, 2020-03)We obtain the holographic complexity of an evaporating black hole in the semi-classical RST model of two-dimensional dilaton gravity, using a volume prescription that takes into account the higher-dimensional origin of the model. For classical black ...
-
(Springer Science and Business Media LLC, 2020-05-01)We find the holographic dual to the three classes of superconformal Janus interfaces in N = 4 SYM that preserve three-dimensional N = 4, N = 2, and N = 1 supersymmetry. The solutions are constructed in five-dimensional SO(6) maximal gauged supergravity ...
-
(Springer Nature, 2016-12)We explore a version of black hole complementarity, where an approximate semiclassical effective field theory for interior infalling degrees of freedom emerges holo-graphically from an exact evolution of exterior degrees of freedom. The infalling degrees ...
-
(Springer Science and Business Media LLC, 2020-06-01)We establish an attractor mechanism for the horizon metric of asymptotically locally AdS4 supersymmetric black holes. The horizon is a smooth Riemann surface with arbitrary metric at asymptotic infinity which is fixed to the constant curvature metric ...
-
(American Physical Society (APS), 2019-04-15)Hydrodynamics is a theory of long-range excitations controlled by equations of motion that encode the conservation of a set of currents (energy, momentum, charge, etc.) associated with explicitly realized global symmetries. If a system possesses ...

(Springer Science and Business Media LLC, 2018-10-25)Mutations in genes encoding subunits of the phagocyte NADPH oxidase complex are recognized to cause chronic granulomatous disease (CGD), a severe primary immunodeficiency. Here we describe how deficiency of CYBC1, a previously uncharacterized protein ...
-
(Frontiers Media SA, 2020-06-12)The innate immune system constitutes the first line of defense against invading pathogens, regulating the normal microbiota and contributes to homeostasis. Today we have obtained detailed knowledge on receptors, signaling pathways, and effector molecules ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-05)Sponges (phylum Porifera) are considered one of the oldest extant lineages of the animal kingdom. Their close association with microorganism makes them suitable for studying early animal-microbe symbiosis and expanding our understanding of host-microbe ...
-
(Public Library of Science (PLoS), 2016-11-21)Populations of rock ptarmigan (Lagopus muta) in Iceland fluctuate in multiannual cycles with peak numbers c. every 10 years. We studied the ptarmigan-parasite community and how parasites relate to ptarmigan age, body condition, and population density. ...
-
(American Geophysical Union (AGU), 1996-12-01)P‐to‐S conversions from the two primary discontinuities near 410 and 660 km depth (P410s and P660s phases) are evident in particle motions and receiver functions of teleseismic body waves recorded by broadband seismic stations in Iceland. The average ...

(EADTU, 2018-10)At the University of Iceland, School of Education (UISE), a group of faculty members has been examining its teacher education programme, which has been offered online with face-to-face sessions since the early 90’s as well as being offered as campus-based. ...
-
(Inderscience Publishers, 2015)This research sought to explore teachers’ views, in terms of the assertion that creative development is important within the National Curriculum. It aimed to identify the extent to which creative development is supported within the current curriculum ...

(MDPI AG, 2020-06-20)The Arctic Council is an intergovernmental forum promoting cooperation, coordination and interaction among Arctic states, indigenous communities, and peoples on issues of common importance. The rising geo-political importance of the Arctic and the onset ...
-
(Frontiers Media SA, 2017-08-21)The influence of game location on performance has been widely examined in sport contexts. Concerning soccer, game-location affects positively the secondary and tertiary level of performance; however, there are fewer evidences about its effect on game ...

(University of Iceland Press, 2006)Hnattræn hlýnun (global warming) er eitt mest umrædda málefni í heiminum í dag, enda er hlýnunin þegar farin að hafa gífurlegar afleiðingar. Mikil gögn liggja fyrir um hvernig þættir veður- og náttúrufars eru að breytast. Gefur bókin gott yfirlit yfir ...
