    In the present article, we analyze a project in a heavy industry plant in Iceland in which the management aims to hire an equal number of women and men and, thereby, to work against the gender segregation of work. For their efforts, called the 50/50 ...

    Activity space (AS) is a measure of spatial behavior used to summarize the mobility behavior of individuals. Current studies often highlight the fact that AS is highly complex and multidimensional in character. Therefore, the need for more holistic ...
  • Loftsdóttir, Kristín (Informa UK Limited, 2015-10-02)
    This discussion stresses that looking at countries on the margins of European colonial rule can be useful when considering the wider dynamics of the present, reflecting the persistence of colonial discourses and how racism “endures”. Iceland’s colonial ...
  • Steen-Larsen, H. C.; Sveinbjörnsdóttir, Árný; Jonsson, Th.; Ritter, F.; Bonne, J.-L.; Masson-Delmotte, V.; Sodemann, H.; Blunier, T.; Dahl-Jensen, D.; Vinther, B. M. (American Geophysical Union (AGU), 2015-06-24)
    The isotopic composition of near surface (or planetary boundary layer) water vapor on the south coast of Iceland (63.83°N, 21.47°W) has been monitored in situ between November 2011 and April 2013. The calibrated data set documents seasonal variations ...

    In situ, airborne and satellite measurements are used to characterize the structure of water vapor in the lower tropical troposphere—below the height, z∗, of the triple-point isotherm, T∗. The measurements are evaluated in light of understanding of how ...
  • Benetti, M.; Reverdin, G.; Aloisi, G.; Sveinbjörnsdóttir, Árný (American Geophysical Union (AGU), 2017-06)
    The surface ocean hydrological cycle is explored based on ∼300 new δ18O and δD measurements from surface waters of the Atlantic Ocean and the Mediterranean Sea over the period 2010–2016. Our approach combines these surface observations with salinity ...
  • Benetti, M.; Lacour, Jean-Lionel; Sveinbjörnsdóttir, Árný; Aloisi, G.; Reverdin, G.; Risi, C.; Peters, A. J.; Steen‐Larsen, H. C. (American Geophysical Union (AGU), 2018-03-10)
    We propose a framework using water vapor isotopes to study mixing processes in the marine boundary layer (MBL) during quiescent conditions, where we expect evaporation to contribute to the moisture budget. This framework complements the existing models, ...
  • Thorhallsson, Andri Isak; Stefansson, Andri; Kovalov, Danyil; Karlsdóttir, Sigrún (Elsevier BV, 2020-05)
    This paper reports the results of corrosion study for carbon steel, austenitic stainless steel, as well as titanium and nickel-based alloys which were tested in a simulated superheated geothermal environment (SSGE) in flow-through reactors to investigate ...
  • Palonen, H.; Magnus, Fridrik; Hjörvarsson, Björgvin (American Physical Society (APS), 2018-10-12)
    The conventional magnetic proximity effect and double-proximity effects were studied in a set of fully coherent high-quality Fe/Fe0.32V0.68 superlattices. Applying a simple model to the saturation magnetization, it is seen that the magnetic proximity ...
  • Thorarinsdottir, Kristbjorg Anna; Palonen, H.; Palsson, G. K.; Hjörvarsson, Björgvin; Magnus, Fridrik (American Physical Society (APS), 2019-05-21)
    Here we study the magnetic proximity effect in amorphous layered magnets of alternating high- and low-Tc materials using magnetometry and polarized neutron reflectivity. By altering the thickness of either the high- or low-Tc layer we are able to extract ...
  • George, Sebastian; Kádas, Krisztina; Jönsson, Petra E.; Muscas, Giuseppe; Magnus, Fridrik; Eriksson, Olle; Delin, Anna; Andersson, Gabriella (Springer Science and Business Media LLC, 2020-06-12)
    Using a combination of extended X-ray absorption fine structure measurements, stochastic quenching (SQ) calculations and Voronoi tessellation analysis, the local atomic environments in thin films of amorphous SmxCo1−x (x= 0.10, 0.22 and 0.35) are ...

    Promiscuity, the ability of an enzyme to catalyze diverse activities using the same active site, sets up the stage for the evolution of complex organisms through gene duplication and specialization. The detection of promiscuous motifs is crucial to ...

    Á fyrsta ári þessarar aldar skrifaði þáverandi formaður Íslenskrar málnefndar, Kristján Árnason prófessor, grein í Málfregnir þar sem hann skilgreindi ágætlega tvenns konar vanda sem hann taldi íslenskt mál myndi standa frammi fyrir á nýbyrjaðri öld; ...
  • Hjörleifsson, Jens G; Ásgeirsson, Bjarni (Wiley, 2018-12-21)
    Most enzymes are homodimers or higher order multimers. Cold‐active alkaline phosphatase from Vibrio splendidus (VAP) transitions into a dimer with very low activity under mild denaturation conditions. The desire to understand why this dimer fails to ...
