(2022-11-22)BACKGROUND: Previous studies suggest poor pulmonary function is associated with increased burden of cerebral white matter hyperintensities and brain atrophy among elderly individuals, but the results are inconsistent. OBJECTIVE: To study the cross-sectional ... -
(Public Library of Science (PLoS), 2018-04-02)Background The term Asthma and COPD Overlap (ACO) describes a condition where asthma and COPD overlap. We aimed to investigate associations between ACO and insomnia and respiratory symptoms, and to investigate the prevalence of ACO and the characteristics ...

(2022-07-09)Curcumin has been demonstrated to exhibit photosensitized bactericidal activity. However, the full exploitation of curcumin as a photo-pharmaceutical active principle is hindered by fast deactivation of the excited state through the transfer of the ...

(2024-01)The asymmetric synthesis of polyunsaturated triene C18:3 n-3 and C18:3 n-6 methoxylated ether lipids (MEL) of the 1-O-alkyl-sn-glycerol type is described as possible structural candidates for a triene C18:3 MEL of an unknown identity found in a mixture ...

(Cambridge University Press (CUP), 2017-01-25)We assess ice loss and velocity changes between 1985 and 2014 of three tidewater and fiveland terminating glaciers in Godthabsfjord (Nuup Kangerlua), Greenland. Glacier thinning accounted for 43.8 +/- 0.2 km(3) of ice loss, equivalent to 0.10 mm eustatic ...

(Wiley, 2019-12-13)Objectives A multi‐isotope study was conducted on individuals buried at Skriðuklaustur monastery (AD 1493–1554) to investigate their geographic origins and dietary composition. Comparative material from individuals excavated from Skeljastaðir, an ...

(Stofnun stjórnsýslufræða og stjórnmála við Háskóla Íslands, 2016-12-19)Þessi rannsókn leitast við að útskýra tímamótaákvörðun í þjónustu við fatlað fólk á Íslandi. Opinber stefnumótun hefur löngum einkennst af hægfara breytingum, sem gerast í smáum skrefum. Stundum bregður þó svo við að meiriháttar breytingar verða og ...

(University of Iceland, School of Health Sciences, Faculty of Food Science and Nutrition, 2019-02)The aim of the thesis work was to identify and characterise different trypsin isoenzymes from a benzamidine-purified Atlantic cod (Gadus morhua) trypsin isolate. Another aim was to test the ability of cod trypsin to deactivate upper respiratory tract ...

(European Geosciences Union, 2019)North-Atlantic Cold-air outbreaks are weather events characterised by extensive fluxes of latent heat to theatmosphere. Understanding the water budget of these weather events is important for the weather impact indownstream ...
-
(Copernicus GmbH, 2017-09-12)The separation of volcanic ash and sulfur dioxide (SO2) gas is sometimes observed during volcanic eruptions. The exact conditions under which separation occurs are not fully understood but the phenomenon is of importance because of the effects volcanic ...
-
(Springer Nature, 2017-09-20)Understanding how edge misfit dislocations (MDs) form in a GeSi/Si(001) film has been a long standing issue. The challenge is to find a mechanism accounting for the presence of these dislocations at the interface since they are not mobile and cannot ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2022-06-27)The research described in this thesis is part of a network project involving the growth of metal nanostructures on surfaces of solids, a Horizon 2020 project titled ELENA. The part of the project described here involved the use of various approaches ...
-
(Springer Nature, 2017-08-15)The underlying mechanism driving the structural amorphous-to-crystalline transition in Group VI chalcogenides is still a matter of debate even in the simplest GeTe system. We exploit the extreme sensitivity of 57Fe emission Mössbauer spectroscopy, ...
-
(American Physical Society (APS), 2022-06-27)We provide a theoretical background for electric-field-assisted thermally activated writing and deleting of magnetic skyrmions in ultrathin transition-metal films. We apply an atomistic spin model, which includes the exchange interaction, the ...
-
(2023-01-16)Objective: Most research on safety of attention-deficit/hyperactivity disorder (ADHD) medications during pregnancy concerns central nervous system stimulants, while little is known about the safety of atomoxetine, a primary treatment alternative. We ...

(Springer Science and Business Media LLC, 2019-10-17)Attention-deficit/hyperactivity disorder (ADHD) is a highly heritable common childhood-onset neurodevelopmental disorder. Some rare copy number variations (CNVs) affect multiple neurodevelopmental disorders such as intellectual disability, autism ...

(2020-12-16)In the past few years, millions have been forced to leave their homes seeking refuge in other countries, most displaced from Muslim majority countries. The inflow of refugees and recent terrorist attacks in Europe may have reinforced prejudice against ... -
(University of Iceland, School of Health Sciences, Faculty of Psychology, 2021-12-10)Our eyes are the primary gates to the visible world around us. Yet, whatever we perceive involves a translation of the patterns of the photons hitting our retinas into mental representations. It could be argued that visual perception is merely an ...
