Effects of Nanoparticles (Al2O3 and TiO2), Fibers and Fly Ash on Cementitious and Non-cementitious Materials at Room Temperature and 80°C Curing Temperature: Experimental and Empirical Modelling Studies
(Master thesis, 2022)Cement constitutes undoubtedly one of the most important well barrier elements, in terms of maintaining well integrity by preventing undesired flow of reservoir fluid into the wellbore. NORSOK D-010 standard dictates that ... -
Effects of Nanoparticles on the Neat Geopolymer: Experimental, Economic and Environmental Impact Studies
(Master thesis, 2023)In the oil and gas industry, cement is used for well construction and plug abandonment operations acting as a barrier element. According to NORSOK D-10, the well should be designed to control undesired flow from the reservoir ... -
Effects of nonlinearities in the Equation of motion for one degree of freedom systems
(Masteroppgave/UIS-TN-IKM/2017;, Master thesis, 2017-06-12)Most natural phenomena in the world have a nonlinear behaviour. If systems are to be described by linear equations they must follow the superposition principle. The superposition principle, consisting of additivity and ... -
Effects of nutritional interventions in individuals with chronic obstructive lung disease: A systematic review of randomized controlled trials
(Peer reviewed; Journal article, 2021)Background The role of nutrition and dietary patterns has been widely investigated in cancer, cardiovascular disease, and diabetes, but there are limited data on nutritional impact on COPD. This systematic review ... -
Effects of permeability on CO2 dissolution and convection at reservoir temperature and pressure conditions: A visualization study
(Peer reviewed; Journal article, 2020-06)When CO2 is injected into aquifers, CO2 will dissolve into the water phase. CO2 dissolution initiated by diffusion, will increase the density of the water phase and thereby commence the convective flow of CO2. The objective ... -
The effects of pH, time and temperature on the stability and viscosity of cellulose nanocrystal (CNC) dispersions: implications for use in enhanced oil recovery
(Journal article; Peer reviewed, 2017-08)Cellulose nanocrystals (CNC) are currently being investigated as potential additives for enhanced oil recovery (EOR). Presented in this paper is a study investigating the effects of different physical and chemical environments ... -
Effects of pharmaceuticals on oxidative stress genes in Atlantic cod (Gadus morhua) caged near the marine wastewater treatment plant discharge of Stavanger.
(Bachelor thesis, 2022)Atlantic cod caged in three different locations at the coastline of Stavanger, were monitored to look at the potential oxidative stress effect caused by pharmaceutical contaminations in selected areas. The first station ... -
Effects of polymer adsorption on the effective viscosity in microchannel flows: phenomenological slip layer model from molecular simulations
(Journal article; Peer reviewed, 2018-10)Molecular simulations (Dissipative Particle Dynamics - DPD) were used to quantify the effect of polymer adsorption on the effective shear viscosity of a semi-dilute polymer solution in microchannel Poseuille flow. It is ... -
Effects of pore fluids on quasi‐static shear modulus caused by pore‐scale interfacial phenomena
(Peer reviewed; Journal article, 2019)It is evident from the laboratory experiments that shear moduli of different porous isotropic rocks may show softening behaviour upon saturation. The shear softening means that the shear modulus of dry samples is higher ... -
Effects of post-harvest storage conditions on volatile organic compounds and important fruit quality parameters in tomato fruit.
(Master thesis, 2021)Effects of storage conditions on tomato flavor has been of recent interest in terms of flavor and post-harvest handling. This study aims to establish an analytical procedure to analyze volatile organic compounds (VOCs) ... -
Effects of Potential Determining Ions and pH on the Wettability of Intermediate Wet Outcrop Limestone
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-13)The intent of this study is to determine if the wettability of slightly oil wet limestone can be shifted toward water wet using “Smart Water”. The theory of “Smart Water” in carbonates proposes that increasing the composition ... -
Effects of protein enrichment in texture modified and minced fish products
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-06-15)The aim of this thesis was to develop two protein enriched products based on haddock and silver smelt, reaching the level of total protein in the utilized fish raw material. Both products were enriched by whey protein ... -
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 ... -
Effects of regular classes in outdoor education settings: A systematic review on students' learning, social and health dimensions
(Journal article; Peer reviewed, 2017-05)Background: Participants in Outdoor Education Programmes (OEPs) presumably benefit from these programmes in terms of their social and personal development, academic achievement and physical activity (PA). The aim of this ... -

Effects of relative performance feedback: A quasi-experiment in collaboration with a Norwegian insurance company
(Master thesis, 2022)While there exists extensive research exploring the effects of relative performance feedback, there is limited evidence from experiments in the field, and the emotional responses of agents have been widely neglected. This ... -
