(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2017-02-08)Anthropogenic CO2 emissions, which are resulting in ocean acidification and a decrease in the saturation state for calcium carbonate (Ω), are a particular threat to calcifying marine biota. The aim of this thesis is to fill important knowledge gaps ... -
(2021-04-09)Direct optimization methods for the calculation of ground and excited electronic states are presented for both total density and orbital-density-dependent functionals. The methods have been developed for various types of basis sets including localized ...

(Informa UK Limited, 2019-05-10)An experimentally based prediction model of road abrasion wear due to studded tyres is available in Sweden and has been found to work well. However, it has not been validated since 2007, and since then road surfaces and tyre design have developed, and ...
-
(Wiley, 2018-01-03)This is a call for action to scientific journals to introduce reporting requirements for toxicity and ecotoxicity studies. Such reporting requirements will support the use of peer‐reviewed research studies in regulatory decision‐making. Moreover, this ...

(MDPI AG, 2019-08-11)Gestational diabetes mellitus (GDM) is predominantly a lifestyle disease, with diet being an important modifiable risk factor. A major obstacle for the prevention in clinical practice is the complexity of assessing diet. In a cohort of 1651 Icelandic ...
-
(Wiley, 2017-09-13)Social learning can be fundamental to cohesive group living, and schooling fishes have proven ideal test subjects for recent work in this field. For many species, both demographic factors, and inter‐ (and intra‐) generational information exchange are ...
-
(Melbourne Graduate School of Education, University of Melbourne, Australia., 2018-11-04)In this article, I will explore and discuss the meaning of the concept of critical thinking when applied to Icelandic education from a Deweyan perspective. I will explore the concept of critical thinking by referring to the Icelandic philosopher Páll ...

(IOP Publishing, 2017-01-05)Life-cycle assessment (LCA) is an established methodology that can provide decision-makers with comprehensive data on the environmental impacts of products and processes during the entire life cycle. However, the literature on building LCAs consists ...
-
(Wiley, 2020-02-17)Purpose: Compare (a) nonmitomycin C (MMC) trabeculectomy and 1.5% dexamethasone nanoparticle (DexNP) eye drops postoperatively with (b) trabeculectomy with MMC and Maxidex® eye drops postoperatively. Methods: Randomized prospective single masked clinical ...
-
(Elsevier BV, 2021-04)Background Identifying predictive factors for a normal outcome at admission in the labor ward would be of value for planning labor care, timing interventions and in preventing labor dystocia. Clinical assessments of fetal head station and position ...
-
(Springer Science and Business Media LLC, 2020-06-13)Purpose: Obesity increases the risk of several cancers, but the influence of bariatric surgery on the risk of individual obesity-related cancers is unclear. This study aimed to assess the impact of bariatric surgery on cancer risk in a multi-national ...

The capability of recurrent neural networks to predict turbulence flow via spatiotemporal features (IEEE, 2022-07-06)This study presents a deep learning (DL) neural network hybrid data-driven method that is able to predict turbulence flow velocity field. Recently many studies have reported the application of recurrent neural network (RNN) methods, particularly the ...
-
(Elsevier BV, 2020-06)The CarbFix method was upscaled at the Hellisheiði geothermal power plant to inject and mineralize the plant’s CO2 and H2S emissions in June 2014. This approach first captures the gases by their dissolution in water, and the resulting gas-charged water ...
-
(Elsevier BV, 2018-08)Sustainable development and climate change mitigation have become guiding policy principles in many welfare states. However, the traditional role of a welfare state is to guarantee the economic stability, jobs and welfare for its citizens. Sustainable ...
-
(MDPI AG, 2016-11-08)The greenhouse gas (GHG) emissions caused by tourism have been studied from several perspectives, but few studies exist that include all direct and indirect emissions, particularly those from aviation. In this study, an input/output-based hybrid ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2022-11)In the wake of increasing awareness of global warming, peatland conservation and restoration receive impetus by efforts to sequester carbon. Peatlands comprise a significant component of the global carbon cycle as they store up to 30% of global ...
-
(Elsevier BV, 2020-09)Oldoinyo Lengai, located in the Gregory Rift in Tanzania, is a world-famous volcano owing to its uniqueness in producing natrocarbonatite melts and because of its extremely high CO2 flux. The volcano is constructed of highly peralkaline [PI = molar ...

Carbonic Anhydrase Inhibitors of Different Structures Dilate Pre-Contracted Porcine Retinal Arteries (MDPI AG, 2019-01-22)Carbonic anhydrase inhibitors (CAIs), such as dorzolamide (DZA), are used as anti-glaucoma drugs to lower intraocular pressure, but it has been found that some of these drugs act as vasodilators of retinal arteries. The exact mechanism behind the ...
-
(Elsevier BV, 2019-08)Background: Despite the epidemic of cardiovascular disease and the benefits of cardiac rehabilitation (CR), availability is known to be insufficient, although this is not quantified. This study ascertained CR availability, volumes and its drivers, and ...
