(2023-08-17)The aim of this study was to investigate a potential all-year vulnerability of people with seasonal mood fluctuations. We compared behavioral and neurophysiological responses to emotional stimuli in summer between people who report seasonal symptoms ... -
(Agricultural University of Iceland, 2020)Thirty-seven dairy cows of the Icelandic breed were used in a change-over design experiment. The aim was to analyse the effects of moderate addition of high-palmitic acid (C16:0) fat supplement to a grass silage-based diet. There were three experimental ...

(Cambridge University Press (CUP), 2018-05-22)The Holocene climatic optimum was a period 8–5 kyr ago when annual mean surface temperatures in Greenland were 2–3°C warmer than present-day values. However, this warming left little imprint on commonly used temperature proxies often used to derive the ...

(MDPI AG, 2020-01-29)Acute exercise influences human cognition, and evidence suggests that learning can be improved. According to the cognitive-energetic approach towards exercise cognition, exercise represents a stressor that elevates physiological arousal, which, in turn, ...
-
(MDPI AG, 2019-02-26)Acute exercise has an influence on human cognition, and both theoretical approaches and previous investigations suggest that the learning process can be facilitated. A distinction has been made however, between the predominately positive effects on ...
-
(AIP Publishing, 2019-06-07)Critical parameters defining the local nucleation field in amorphous ferromagnetic microwires with positive magnetostriction are obtained analytically through scaling procedures. An exact value of the nucleation field is obtained numerically as a ...
-
(Elsevier BV, 2017-12)Background Postural asymmetries with seating problems are common in adults with cerebral palsy. Aims To analyse the prevalence of asymmetrical limited hip flexion (<90°) in adults with CP, and to evaluate the association between asymmetrical limited ...
-
(AIP Publishing, 2019-03-08)We investigate the effect of atomic ordering on the magnetic anisotropy of Ni80Fe20 at.% (Py). To this end, Py films were grown epitaxially on MgO(001) using dc magnetron sputtering (dcMS) and high power impulse magnetron sputtering (HiPIMS). Aside ...

(University of Iceland, School of Health Sciences, Faculty of Medicine, 2017-12-08)Abstract Psoriasis is a chronic immune-mediated inflammatory skin disease with profound effects on psychosocial wellbeing. Narrowband UVB phototherapy is a known effective treatment for chronic plaque psoriasis and previous studies suggest an ...
-
(Elsevier BV, 2020-09)We theoretically investigate structural stability, electronic and thermal characteristic of boron and nitrogen codoped monolayer graphene using density functional theory and Boltzmann transport equation. Three types of BN dimers, ortho, meta, and para ...
-
(2022-09-28)By the end of July 2021, the majority of the Icelandic population had received vaccination against COVID-19. In mid-July a wave of SARS-CoV-2 infections, dominated by the Delta variant, spread through the population, followed by an Omicron wave in ...
-
(Wiley, 2019-03-06)Molecular serum markers that can identify early reversible osteoarthritis (OA) in horses are lacking. Objectives: We studied serum concentrations of a novel cartilage oligomeric matrix protein (COMP) neo-epitope in horses subjected to short-term exercise ...
-
(Elsevier BV, 2017-09)The stability of magnetic skyrmions against thermal fluctuations and external perturbations is investigated within the framework of harmonic transition state theory for magnetic degrees of freedom. The influence of confined geometry and atomic scale ...
-
(Taiwan Association for Aerosol Research, 2020-05)In order to decrease spreading of Coronavirus disease 2019 (COVID-19) over the world, the activity of many industries has declined, several flights were cancelled and so many people staying home that made drop in fuel consumption in road transport. ...
-
(2021-04-28)The aim of this work was to stabilize doxycycline in mucoadhesive buccal films at room temperature (25◦C). Since doxycycline is susceptible to degradation such as oxidation and epimerization, tablets are currently the only formulation that can keep the ...
-
(1993)Infection and inflammation increase serum triglyceride and cholesterol levels in rodents and rabbits. Endotoxin (LPS) has been used as a model of infection and its effects on triglyceride metabolism have been previously characterized. In the present ...
-
(2022-07-27)The increasing prevalence of asthma is linked to westernization and urbanization. Farm environments have been associated with a lower risk of asthma development. However, this may not be universal, as the association differs across birth cohorts and ...
-
(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 ...
-
(MDPI AG, 2019-01-02)The aim of this study was to determine if increased mortality associated with low levels of serum 25-hydroxyvitamin D (25(OH)D) reflects a causal relationship by using a Mendelian randomisation (MR) approach with genetic variants in the vitamin D ...
-
(Agricultural University of Iceland, 2018)Geothermal areas can be local sources of greenhouse gases, both directly from the geothermal system or because of soil warming effects on biological sources. In this study we repeated field measurements methane (CH4) and nitrous oxide (N2O) fluxes along ...
