Rheological properties of highly concentrated dense packed layer emulsions (w/o) stabilized by asphaltene
(Journal article; Peer reviewed, 2015)Dense packed layers (DPLs) were sedimented and removed from various asphaltene stabilized w/o emulsion batches, and contained aqueous phase volume fractions (ϕ) between 0.701 and 0.808. These values are close to the ... -
Rheological properties of super critical CO2 with Al2O3: Material type, size and temperature effect
(Peer reviewed; Journal article, 2019)CO2 liquid is applied as an Enhanced Oil Recovery (EOR) method in oil reservoirs to increase the displacement efficiency. Because of the high temperature and pressure in the reservoirs, the viscosity of the CO2 decreases ... -
Rheological properties of super critical CO2 with CuO: Multi-scale computational modeling
(Journal article; Peer reviewed, 2018)A multi-scale computational methodology based on the density functional theory and molecular dynamics has been used to investigate the rheological properties of super critical CO2 with CuO nano-particle (NP). Density ... -
Rheology of concrete with crushed aggregate. Influence of volume and composition of matrix, and of sand-stone ratio
(SINTEF AS (ISBN starter med 978-82-14-);, Research report, 2021)The work is a part of the joint industry project "MIKS – Microproportioning of concrete with crushed sand". The overall aim of the work reported here was to provide experimental data as input to the work on the ... -
Rheology of high-capillary number two-phase flow in porous media
(Journal article; Peer reviewed, 2019)Flow of immiscible fluids in porous media at high capillary numbers may be characterized by an effective viscosity. We demonstrate that the effective viscosity is well-described by the Lichtenecker-Rother equation. Depending ... -
Rheology of matrix and SCC with different mineral fillers and admixtures

Rheology of skin mucus from yolk-sac salmon fry
(Journal article; Peer reviewed, 2020)As part of our project “Microbial contributions to the Atlantic salmon (Salmo salar) skin mucosal barrier” we have explored techniques to investigate and characterise the rheological properties of the skin mucus of yolk-sac ... -
Rheumatoid arthritis, disease-modifying antirheumatic drugs and risk of major osteoporotic fracture: prospective data from the HUNT Study, Norway
(Peer reviewed; Journal article, 2023)Objectives Rheumatoid arthritis has been associated with increased fracture risk. New treatments have improved the course of the disease substantially, but it is not clear if this influences fracture risk. We examined if ... -
Rhinosinusitis without Nasal Polyps in COPD
(Peer reviewed; Journal article, 2020)The validity of the united airway disease concept for rhinosinusitis (RS) and chronic obstructive pulmonary disease (COPD) has been questioned because of methodological limitations in previous studies. In this study we ... -
Rhinosinusitis without nasal polyps is associated with poorer health-related quality of life in COPD
(Peer reviewed; Journal article, 2021)Rhinosinusitis without nasal polyps (RSsNP) is prevalent in COPD. Previous studies on its association with health-related quality of life (HRQoL) have limitations, and RSsNP is currently not recognized as a comorbidity. ... -
Rhizomic learning: How environmental nongovernmental organizations (ENGOs) acquire and assemble knowledge
(Peer reviewed; Journal article, 2020)It has been a common assumption that the knowledge practices of environmental organisations (ENGOs) is largely based on interaction with environmental research. Implied in such assumptions is the idea that ENGOs are ... -
Rich and Naïve? Assessing the Effects of Norwegian Aid on Political Corruption, 1980–2018
(Peer reviewed; Journal article, 2020)The effectiveness of aid is heatedly debated in academia and policy circles. Annually, billions of dollars are transferred from industrialized countries to developing countries out of moral and practical concerns. Can aid ... -
A rich dataset of hourly residential electricity consumption data and survey answers from the iFlex dynamic pricing experiment
(Peer reviewed; Journal article, 2023)The iFlex field experiment was conducted to understand if and how households change their power consumption in response to variable hourly electricity prices. This experiment was conducted in several Norwegian regions, and ... -
Rickettsia conorii is a potent complement activator in vivo and combined inhibition of complement and CD14 is required for attenuation of the cytokine response ex vivo
(Journal article, 2016)Mediterranean spotted fever caused by Rickettsia conorii is a potentially lethal disease characterized by vascular inflammation affecting multiple organs. Studies of R. conorii so far have focused on activation of inflammatory ... -
Ridesharing in Adelaide: Segmentation of users
(Journal article; Peer reviewed, 2021)Ridesharing and the tech companies that enable it have become household names. However, as research has focused on users rather than non-users, much less is known about the latter. Understanding the characteristics, ... -
Riding shotgun – Front-seat research and the socio-material considerations of ethnography on the move
(Peer reviewed; Journal article, 2021)In this article, we explore methodological considerations of using the car as space for ethnographic research on police work. With a socio-material perspective, we are concerned about how the car’s particular materiality ... -
Riemannian formulation and comparison of color difference formulas
(Journal article; Peer reviewed, 2012)Study of various color difference formulas by the Riemannian approach is useful. By this approach, it is possible to evaluate the performance of various color difference formulas having different color spaces for measuring ... -
A riemannian geometry theory of synergy selection for visually-guided movement
(Journal article; Peer reviewed, 2021)Bringing together a Riemannian geometry account of visual space with a complementary account of human movement synergies we present a neurally-feasible computational formulation of visuomotor task performance. This cohesive ... -
The Riemannian Geometry Theory of Visually-Guided Movement Accounts for Afterimage Illusions and Size Constancy
(Peer reviewed; Journal article, 2022)This discussion paper supplements our two theoretical contributions previously published in this journal on the geometric nature of visual space. We first show here how our Riemannian formulation explains the recent ... -
Riesz projection and bounded mean oscillation for Dirichlet series
(Peer reviewed; Journal article, 2022)We prove that the norm of the Riesz projection from L∞(Tn) to Lp(Tn) is 1 for all n≥1 only if p≤2, thus solving a problem posed by Marzo and Seip in 2011. This shows that Hp(T∞) does not contain the dual space of H1(T∞) ...
