(2022-06-16)The interaction of low-energy electrons (LEEs) with neutral molecules plays an important role in various applications. In focused electron beam induced deposition (FEBID), a direct-write 3D nanofabrication technique, a high-energy focused electron beam ... -
(Wiley, 2019-10-04)Evolutionary theories of seasonal migration generally assume that the costs of longer migrations are balanced by benefits at the non-breeding destinations. We tested, and rejected, the null hypothesis of equal survival and timing of spring migration ...

(Elsevier BV, 2018-09)Objectives: To describe the relationship between the extent of primary aortic repair and the incidence of reoperations after surgery for type A aortic dissection. Methods: A retrospective cohort of 1159 patients treated for type A aortic dissection at ...
-
(Elsevier BV, 2020-06)Background: Emerging evidence suggests that androgens and estrogens have a role in respiratory health, but it is largely unknown whether levels of these hormones can affect lung function in adults from the general population. This study investigated ...

(University of Iceland, School of Health Sciences, Faculty of Psychology, 2021-12-02)The field of lower limb prosthetics has advanced rapidly in the past two decades with increasingly sophisticated devices becoming available each year. Nevertheless, function has yet to be fully restored for people with lower limb amputation. Active ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-10-27)Focused electron beam induced deposition (FEBID) is a nanofabrication technique wherein electron-induced reactions are used to deposit pure metals from organometallic precursors under the area of a primary electron beam. It can be used to directly ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-12-15)Focused electron beam induced deposition (FEBID) is a direct-write 3D nanofabrication technique, which works on the principle of electron-induced molecular decomposition. In FEBID, a high-energy focused electron beam dissociates the precursor molecules ...

(Wiley, 2018-10-08)The Harletz loess‐palaeosol sequence is located in northwestern Bulgaria and represents an important link between well‐studied loess sequences in eastern Romania and further sites to the west of the Carpathians (e.g. Serbia and Hungary). The aim of ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2023-05)In this thesis we explore Lyapunov functions for stochastic differential equations. Lyapunov functions are a useful tool to study the stability of an equilibrium of such stochastic systems and long term behaviour of solutions around an equilibrium ...
-
(Elsevier BV, 2019-07)LyapXool is a C++ program to compute complete Lyapunov functions and their orbital derivatives for any two- or three-dimensional dynamical system expressed by an autonomous ordinary differential equation. The program is user-friendly and determines the ...
-
(EDP Sciences, 2020-09)Context. The identification of the sources that reionized the Universe and their specific contribution to this process are key missing pieces of our knowledge of the early Universe. Faint star-forming galaxies may be the main contributors to the ionizing ...

(Háskóli Íslands, Hugvísindasvið, Sagnfræði- og heimspekideild, 2021)Á árunum 1874–1915 tók íslenskt samfélag margháttuðum breytingum sem birtust m.a. í efnahags- og félagslegum umskiptum sem tengdust þéttbýlismyndun og lýðræðisþróun. Íslenska sveita-samfélagið átti undir högg að sækja eftir að hafa verið allsráðandi ...

(Menntavísindastofnun Háskóla Íslands, 2020-01-28)Frá því á áttunda áratugnum hefur lýðræðisleg borgaravitund verið markmið íslensks menntakerfis og viðfangsefni Sigrúnar Aðalbjarnardóttur í kennslu og rannsóknum. Á síðustu áratugum hefur orðið vitundarvakning um þessi málefni. Í nýlegu riti Evrópuráðsins, ...

(Nettverket for språknemndene i Norden, 2015)Forskning i forskellige multikulturelle samfund og skoler i de seneste årtier har vist, at mange indvandrere og indvandrerbørn er marginaliserede. Dette har været et incitament for en række publikationer i de seneste årtier om skoleudvikling, læseplaner, ...

(Hugvísindastofnun Háskóla Íslands, 2018)Erlendis hafa þverfaglegar rannsóknir á sviði laga og bókmennta verið blómlegar á undanförnum ártugum. Á fyrstu áratugum tuttugustu aldar mótaðist meðal bandarískra lögfræðikennara hreyfing í kringum þetta efni (e. the law and literature movement) sem ...

(Menntavísindasvið Háskóla Íslands, 2016-12-31)Fjölgun innflytjenda í háskólum á Íslandi kallar á viðbrögð háskólayfirvalda, kennara og háskólasamfélagsins. Íslenskar og erlendar rannsóknir sýna að menntastofnanir, einkum á háskólastigi, gegna mikilvægu hlutverki við að tryggja félagslegt jafnrétti, ...
