(Frontiers Media SA, 2018-03-08)Literacy is the cornerstone of a primary school education and enables the intellectual and social development of young children. Letter-sound knowledge has been identified as critical for developing proficiency in reading. This study explored the ... -
(MDPI AG, 2019-07-25)We recall theoretical studies on transient transport through interacting mesoscopic systems. It is shown that a generalized master equation (GME) written and solved in terms of many-body states provides the suitable formal framework to capture both the ...

(Reykjavik University, School of Science and Engineering, 2019-05-17)Maintaining small physical dimensions of antenna structures is an important consideration for contemporary wireless communication systems. Typically, antenna miniaturization is achieved through various topological modifications of the basic antenna ...

(Springer Science and Business Media LLC, 2018-07-09)Background:Latest research demonstrates a significant improvement in stress-related symptoms in psychological disorders as a result of exercise training (ET). Controlled clinical trials further validate the significance of ET by demonstrating lower ...

(2016-02)Current efficiency loss in aluminum electrolysis happens due to a variety of factors. One such factor is the presence of impurities. Concerns about impurities have been voiced since the quality of raw materials has declined and dry-scrubbers were ...
-
(The Electrochemical Society, 2017)Many factors may contribute to loss of current efficiency (CE) in aluminum reduction and one of them is a presence of impurities. In this work, the effect of phosphorus on CE is studied in a laboratory cell at different current densities. Due to a ...

(MDPI AG, 2018-01-11)Obese children are usually less active than their normal-weight counterparts, although the reasons for this remain unclear. The objective of the present study was to determine how a long-term program (3 years of intervention and 6 months of follow-up ...
-
(Springer Nature, 2017-01-10)We study Coulomb interacting electrons confined in polygonal quantum rings. We focus on the interplay of localization at the polygon corners and Coulomb repulsion. Remarkably, the Coulomb repulsion allows the formation of in-gap states, i.e., ...
-
(Stofnun stjórnsýslufræða og stjórnmála við Háskóla Íslands, 2018-06-20)Í greininni er lagalegt umhverfi íþrótta á Íslandi kannað með hliðsjón af kynjajafnréttissjónarmiðum með hinni fræðilegu lagalegu aðferð (e. doctrinal method). Þannig eru skoðuð sjónarmið sem legið hafa til grundvallar lagasetningu um íþróttir, ...
-
(Frontiers Media SA, 2017-09-08)This study explored whether there is a gender difference in letter-sound knowledge when children start at school. 485 children aged 5-6 years completed assessment of letter-sound knowledge, i.e., large letters; sound of large letters; small letters; ...
-
(Elsevier BV, 2018-03)Iceland as an island country with abundant renewable energy resources has been totally dependent on imported petroleum fuels to meet its transport fuel demand. Transition to electric vehicles (EVs) is of particular interest for Iceland as electricity ...

(Viðskiptafræðideild og hagfræðideild Háskóla Íslands, viðskiptafræðideild Háskólans í Reykjavík og Seðlabanki Íslands., 2011)Staðgöngubjagi stafar af því að neysluhegðun breytist frá þeim tíma sem líður frá því að vogir neyslukörfu eru metnar og fram að notkun hennar við verðbólgumælingu. Neyslukannanir sem liggja til grundvallar mati á vogum 2/3 hluta neyslukörfunnar eru ...

(MDPI AG, 2017-09-21)Three synchronized pulsed Doppler wind lidars were deployed from May 2016 to June 2016 on the shores of a wide Norwegian fjord called Bjornafjord to study the wind characteristics at the proposed location of a planned bridge. The purpose was to investigate ...
-
(IOP Publishing, 2016-08)The hybrid graphene - hexagonal boron nitride (G-hBN) systems offer new routes in the design of nanoscale electronic devices. Using ab initio density functional theory calculations we investigate the dynamics of zig-zag nanoribbons a few interatomic ...
-
(ArXiv, 2016-08)High resolution molecular dynamics simulations with full Coulomb interactions of electrons are used to investigate field emission from a prolate spheroidal tip. The space charge limited current is several times lower than the current calculated with ...
