(Springer Nature, 2017-09-07)Heat pumps use the temperature difference between inside and outside areas to modify a refrigerant, either for heating or cooling. Doing so can lower the need for external heating energy for a household to some extent. The eventual impact depends on ... -
(Læknafélag Íslands, 2019-10-01)INNGANGUR Fjölmargir þættir hafa áhrif á þjónustuþörf og lifun íbúa hjúkrunarheimila, meðal annars inntökuskilyrði fyrir flutningi á hjúkrunarheimili. Markmið rannsóknarinnar var að athuga hvort munur væri á heilsufari, lifun og forspárgildi mismunandi ...

(Wiley, 2020-07-04)Several cryptotephra layers that originate from Icelandic volcanic eruptions with a volcanic explosivity index (VEI) of ≤ 4 and tephra volumes of < 1 km3 have previously been identified in Northern Europe, albeit within a restricted geographical area. ...
-
(American Geophysical Union (AGU), 2018-02-22)Lava flow thicknesses, volumes, and effusion rates provide essential information for understanding the behavior of eruptions and their associated deformation signals. Preeruption and posteruption elevation models were generated from historical stereo ...
-
(American Astronomical Society, 2018-02-15)The local interstellar spectrum (LIS) of cosmic-ray (CR) electrons for the energy range 1 MeV to 1 TeV is derived using the most recent experimental results combined with the state-of-the-art models for CR propagation in the Galaxy and in the heliosphere. ...
-
(OMICS Publishing Group, 2018-12)Background: Hemoglobin transports oxygen in blood yet its concentrations generally decrease with age. The aim of the study was to examine whether hemoglobin is connected with physical function in older age people. Design: Intervention study. Setting: ...
-
(Springer Nature, 2015-12-21)The members of the epidermal growth factor receptor (EGFR) kinase family are important players in breast morphogenesis and cancer. EGFR2/HER2 and EGFR expression have a prognostic value in certain subtypes of breast cancer such as HER2-amplified, ...
-
(Stofnun stjórnsýslufræða og stjórnmála við Háskóla Íslands, 2018-06-20)In recent years there has been a significant shortage of workers in Iceland. The traditional method of arranging temporary work, through direct contracts between employees and employers, has not sufficed. Moreover, there is a skills mismatch that ...

(The Educational Research Institute, 2019-09-12)Rannsóknin fjallar um heterósexíska orðanotkun íslenskra framhaldsskólanemenda sem hefur ýmsar birtingarmyndir. Erlendar rannsóknir benda til að orðanotkunin valdi nemendum óþægindum en fáar íslenskar rannsóknir fjalla um efnið. Markmiðið var að skoða ...

(Springer Science and Business Media LLC, 2019-06-12)In this paper, we extend and analyze a Bayesian hierarchical spatiotemporal model for physical systems. A novelty is to model the discrepancy between the output of a computer simulator for a physical process and the actual process values with a ...
-
(Springer Science and Business Media LLC, 2020-01-18)Vegetation change has consequences for terrestrial ecosystem structure and functioning and may involve climate feedbacks. Hence, when monitoring ecosystem states and changes thereof, the vegetation is often a primary monitoring target. Here, we summarize ...
-
(Public Library of Science (PLoS), 2019-08-23)Background: Fusion genes result from genomic structural changes, which can lead to alterations in gene expression that supports tumor development. The aim of the study was to use fusion genes as a tool to identify new breast cancer (BC) genes with a ...
-
(Wiley-Blackwell, 2017-01)Coastal marine Vibrio cholerae populations usually exhibit high genetic diversity. To assess the genetic diversity of abundant V. cholerae non-O1/non-O139 populations in the Central European lake Neusiedler See, we performed a phylogenetic analysis ...
-
(Frontiers Media SA, 2019-04-09)Few studies have been able to directly measure the seasonal survival rates of migratory species or determine how variable the timing of migration is within individuals and across populations over multiple years. As such, it remains unclear how likely ...
-
(Springer Nature, 2017-10-20)Basalts are recognized as one of the major habitats on Earth, harboring diverse and active microbial populations. Inconsistently, this living component is rarely considered in engineering operations carried out in these environments. This includes ...
-
(Oxford University Press (OUP), 2018-06-04)We present here a survey of high-ionization absorption lines in the afterglow spectra of long-duration gamma-ray bursts (GRBs) obtained with the VLT/X-shooter spectrograph. Our main goal is to investigate the circumburst medium in the natal regions of ...
-
(Springer Science and Business Media LLC, 2020-07-17)Highly nonlinear optical materials with strong effective photon-photon interactions are required for ultrafast and quantum optical signal processing circuitry. Here we report strong Kerr-like nonlinearities by employing efficient optical transitions ...
-
(Oxford University Press (OUP), 2019-11-28)Pulsed electron paramagnetic resonance (EPR) experiments, among them most prominently pulsed electron-electron double resonance experiments (PELDOR/DEER), resolve the conformational dynamics of nucleic acids with high resolution. The wide application ...
-
(MDPI AG, 2020-06-19)The European Union (EU) has made climate change mitigation a high priority though a policy framework called "Clean Energy for all Europeans ". The concept of primary energy for energy resources plays a critical role in how different energy technologies ...
