High-Sensitivity Cardiac Troponin I and T Response Following Strenuous Activity is Attenuated by Smokeless Tobacco: NEEDED (North Sea Race Endurance Exercise Study) 2014
(Peer reviewed; Journal article, 2020)Background Use of snus, a smokeless tobacco product, is increasing in Scandinavia. Strenuous physical activity is associated with an acute increase in high‐sensitivity cardiac troponin (swhs‐cTn) concentrations. Current ... -
Semantic Answer Type Prediction using BERT: IAI at the ISWC SMART Task 2020
(Chapter, 2020)This paper summarizes our participation in the SMART Task of the ISWC 2020 Challenge. A particular question we are interested in answering is how well neural methods, and specifically transformer models, such as BERT, ... -
Actuator and sensor fault estimation based on a proportional multiple‐integral sliding mode observer for linear parameter varying systems with inexact scheduling parameters
(Peer reviewed; Journal article, 2020)This article proposes an approach for the estimation of states, actuator, and sensor faults in nonlinear systems represented by a polytopic linear parameter varying (LPV) system with inexact scheduling parameters. In the ... -
Digitization Methods of Grinding Pins for Technological Process Planning
(Peer reviewed; Journal article, 2020)The paper presents different techniques for digitizing grinding pins and discusses the use of digitalized pins and the results of measurements in technological process planning (TPP), focusing on the challenges of the ... -
Gel Pills for Downhole Pressure Control during Oil and Gas Well Drilling
(Peer reviewed; Journal article, 2020)During drilling of petroleum or geothermal wells, unforeseen circumstances occasionally happen that require suspension of the operation. When the drilling fluid is left in a static condition, solid material like barite may ... -
The impact of seismic interpretation methods on the analysis of faults: a case study from the Snøhvit field, Barents Sea
(Peer reviewed; Journal article, 2021)Five seismic interpretation experiments were conducted on an area of interest containing a fault relay in the Snøhvit field, Barents Sea, Norway, to understand how the interpretation method impacts the analysis of fault ... -
Dependent infrastructure system modeling: A case study of the St. Kitts power and water distribution systems
(Peer reviewed; Journal article, 2020)Critical infrastructure systems underlie the economy, national security, and health of modern society. These infrastructures have become increasingly dependent on each other, which poses challenges when modeling these ... -
Feasibility study of polyetherimide membrane for enrichment of carbon dioxide from synthetic biohydrogen mixture and subsequent utilization scenario using microalgae
(Peer reviewed; Journal article, 2020)In this work, the potential of utilizing a polyetherimide (PEI) hollow-fiber membrane to separate synthetic biohydrogen mixture (H2/CO2) was studied. From the gas separation experiments, where the effects of feed to permeate ... -
Dynamic analysis of spur gear with backlash using ADAMS
(Peer reviewed; Journal article, 2020)Gear tooth profile can deviate from its initial design shape and size as a result of increasing service time under time-varying load, introducing external agents like debris, overheating due to friction, wear, and in ... -
Theoretical Modeling of the Impact of Salt Precipitation on CO2 Storage Potential in Fractured Saline Reservoirs
(Peer reviewed; Journal article, 2020)Deep saline reservoirs have the capacity to hold large volumes of CO2. However, apart from the high brine salinity, which poses an injectivity challenge, a high percentage of saline reservoirs are also fractured. The ... -
Competence constraints for fire and rescue personnel involved in tunnel fire safety as part of the tunnels risk acceptability
(Chapter, 2020)The Commission Directive 2004/54/EC provides minimum safety requirements for tunnels in the trans-European road network and has been implemented in the Norwegian regulatory framework. The Directive states that the tunnel ... -
Factors Affecting the Course of Resuscitation From Cardiac Arrest With Pulseless Electrical Activity in Children and Adolescents
(Peer reviewed; Journal article, 2020)Background: Although in-hospital pediatric cardiac arrests and cardiopulmonary resuscitation occur >15,000/year in the US, few studies have assessed which factors affect the course of resuscitation in these patients. We ... -
A tool to assess learning processes based on the cooperation principle
(Chapter, 2020)A strategy for cooperation in emergency management has been developed and politically agreed upon by the Rogaland County Council, Norway. The region comprised by the strategy consists of many different actors within societal ... -
Development of a constitutive and an auto-inducible high-yield expression system for recombinant protein production in the microalga Nannochloropsis oceanica
(Peer reviewed; Journal article, 2020-09)Photoautotrophic microalgae offer a great potential as novel hosts for efficient recombinant protein production. Nannochloropsis oceanica produces an extraordinarily high content of polyunsaturated fatty acids, and its ... -
Effects of purified anthocyanins in people at risk for dementia: Study protocol for a phase II randomized controlled trial
(Peer reviewed; Journal article, 2020)Background: The number of people with dementia is increasing, with huge challenges for society and health-care systems. There are no disease-modifying therapies available. There is, therefore, an urgent need to identify ... -
Analysis of Greenhouse Gas Emissions from Offshore Wind Turbines
(Master thesis, 2022)Renewable energy resources such as offshore wind turbines are considered as if they do not emit greenhouse gas emissions, as greenhouse gases are not emitted from these resources during electricity generation. However, ... -
Methane–propane hydrate formation and memory effect study with a reaction kinetics model
(Peer reviewed; Journal article, 2020-05)Although natural gas hydrates and hydrate exploration have been extensively studied for decades, the reaction kinetics and nucleation mechanism of hydrate formation is not fully understood. In its early stage, gas hydrate ... -
