Role of the kidneys in acid-base regulation and ammonia excretion in freshwater and seawater fish: implications for nephrocalcinosis
(Journal article; Peer reviewed, 2023)Maintaining normal pH levels in the body fluids is essential for homeostasis and represents one of the most tightly regulated physiological processes among vertebrates. Fish are generally ammoniotelic and inhabit diverse ... -
The role of the northward-directed (sub)surface limb of the Atlantic Meridional Overturning Circulation during the 8.2 ka event
(Peer reviewed; Journal article, 2014-10-24)The so-called "8.2 ka event" is widely regarded as a major Holocene climate perturbation. It is most readily identifiable in the oxygen-isotope records from Greenland ice cores as an approximately 160-year-long cold interval ... -
The role of the sea surface temperature in the atmospheric seasonal cycle of the equatorial Atlantic
(Journal article; Peer reviewed, 2018)We investigate the role of sea surface temperature (SST) and land surface temperature (LST) in driving the seasonal cycle of the atmosphere (surface winds and precipitation) in the tropical Atlantic. For this we compare ... -
The role of the Southern Ocean in past global biogeochemical cycling
(Doctoral thesis, 2020-04-27)This thesis describes several recent advances on the role of the Southern Ocean in past global biogeochemical cycling. We focus on the ocean of the Last Glacial Maximum (LGM) and the Pleistocene epoch and apply proxies of ... -
The Role of the Stratosphere in Subseasonal to Seasonal Prediction: 1. Predictability of the Stratosphere
(Journal article; Peer reviewed, 2019-11-18)The stratosphere has been identified as an important source of predictability for a range of processes on subseasonal to seasonal (S2S) time scales. Knowledge about S2S predictability within the stratosphere is however ... -
The Role of the Stratosphere in Subseasonal to Seasonal Prediction: 2. Predictability Arising From Stratosphere-Troposphere Coupling
(Journal article; Peer reviewed, 2020)The stratosphere can have a significant impact on winter surface weather on subseasonal to seasonal (S2S) timescales. This study evaluates the ability of current operational S2S prediction systems to capture two important ... -
The role of transmission and energy storage in European decarbonization towards 2050
(Journal article; Peer reviewed, 2021)This paper presents analyses of the development of the European electricity sector that is in line with the climate and energy targets of the European Union for 2030 and 2050. The role of energy storage and transmission ... -
Role of volcanic forcing on future global carbon cycle
(Peer reviewed; Journal article, 2011-06-16)Using a fully coupled global climate-carbon cycle model, we assess the potential role of volcanic eruptions on future projection of climate change and its associated carbon cycle feedback. The volcanic-like forcings are ... -
The Role of Wettability Alteration in Subsurface CO2 Storage: Modeling and Numerical Analysis
(Doctoral thesis, 2021-12-06)This dissertation is aimed to provide mathematical frameworks to assess the large-scale deployment of CO2 in a subsurface formation, where the formation wettability is assumed to be altering through exposure time to the ... -
Role of wind stress in driving SST biases in the tropical Atlantic
(Journal article; Peer reviewed, 2019-03-13)Coupled climate models used for long-term future climate projections and seasonal or decadal predictions share a systematic and persistent warm sea surface temperature (SST) bias in the tropical Atlantic. This study attempts ... -
Roles of M-phase cell cycle regulatory paralogs in the urochordate Oikopleura dioica
(Doctoral thesis, 2018-11-16)Cell cycle progression is controlled by a series of regulators with complex spatialtemporal dynamics, ensuring faithful transitions of different phases. The urochordate Oikopleura has systemically employed diverse cell ... -
Roles of three putative salmon louse (Lepeophtheirus salmonis) prostaglandin E2 synthases in physiology and host–parasite interactions
(Journal article; Peer reviewed, 2021)Background The salmon louse (Lepeophtheirus salmonis) is a parasite of salmonid fish. Atlantic salmon (Salmo salar) exhibit only a limited and ineffective immune response when infested with this parasite. Prostaglandins ... -
Room of Errors - Feasibility and Design of a Simulation Training Concept in VR with Intentional Simulation Errors
(Master thesis, 2022-06-01)In 2020, 13.1 percent of somatic hospital stays in Norway led to hospital-acquired complications or injuries. One way of working to prevent these events may be found in the education of health personnel. Nursing study ... -
Room-Scale CO2 Injections in a Physical Reservoir Model with Faults
(Journal article; Peer reviewed, 2024)We perform a series of repeated CO2 injections in a room-scale physical model of a faulted geological cross-section. Relevant parameters for subsurface carbon storage, including multiphase flows, capillary CO2 trapping, ... -

Rotation and Turbulence in Peripheral Heavy Ion Collisions
(Doctoral thesis, 2014-12-16)In our computational fluid dynamics (CFD) calculations the Kelvin-Helmholtz instability (KHI) starts to develop in peripheral collisions. At high energies the shear viscosity of the Quark Gluon Plasma (QGP) flow is becoming ... -
Rotation and Turbulent Instability in Peripheral Heavy Ion Collisions
(Journal article; Peer reviewed, 2014-04-29)In recent years fluid dynamical processes became a dominant direction of research in high energy heavy ion reactions. The Quark-gluon Plasma formed in these reactions has low viscosity, which leads to significant fluctuations ... -
Rotation in an exact hydrodynamical model
(Peer reviewed; Journal article, 2014-08-01)We study an exact and extended solution of the fluid dynamical model of heavy ion reactions and estimate the rate of slowing down of the rotation due to the longitudinal and transverse expansion of the system. The initial ...
