Revisiting transverse momentum broadening in dense QCD media
(Journal article; Peer reviewed, 2021)We reconsider the problem of transverse momentum broadening of a highly energetic parton suffering multiple scatterings in dense colored media, such as the thermal quark-gluon plasma or large nuclei. In the framework of ... -
Reworking of atmospheric sulfur in a Paleoarchean hydrothermal system at Londozi, Barberton Greenstone Belt, Swaziland
(Peer reviewed; Journal article, 2016-07)Anomalous fractionation of the minor isotopes of sulfur (Δ33S, Δ36S) in Archean pyrite is thought to reflect photochemical reactions in an anoxic atmosphere, with most samples falling along a reference array with Δ36S/Δ33S ... -
Rheological properties of hydrophobically modified anionic polymers: The effect of varying salinity in polymer solution
(Master thesis, 2017-06-16)A new class of polymers, named ‘hydrophobically modified water-soluble polymers’, has been developed as an alternative to the more commonly used polyelectrolytes in enhanced oil recovery (EOR) applications. These polymers ... -
Rheology of Synthetic Polymers in Porous Media
(Master thesis, 2014-06-02)This master thesis is written out of the Centre for Integrated Petroleum Research (UNI CIPR) at the University of Bergen (UiB). The aim of this study has been to describe the polymer rheology of the high molecular weight ... -
Rhythmic Clock Gene Expression in Atlantic Salmon Parr Brain
(Journal article; Peer reviewed, 2021)To better understand the complexity of clock genes in salmonids, a taxon with an additional whole genome duplication, an analysis was performed to identify and classify gene family members (clock, arntl, period, cryptochrome, ... -
Ridge Extraction, and Illustrative Visualization of an FTLE Flow Field.
(Master thesis, 2012-06-01)Illustrative visualization of a flow is an area that is proving to be interesting and in later years something that have been somewhat explored, it can provide some very interesting results and in this thesis we find the ... -
Rift kinematics preserved in deep-time erosional landscape below the northern North Sea
(Journal article; Peer reviewed, 2022)Our understanding of continental rifting is, in large parts, derived from the stratigraphic record. This record is, however, incomplete as it does not often capture the geomorphic and erosional signal of rifting. New 3D ... -
Rigorous derivation of some asymptotic models for free water surfaces and interfaces
(Doctoral thesis, 2024-04-26)Opprinnelsen til moderne matematisk hydrodynamikk kan spores tilbake til 1700-tallet. I 1757 publiserte Euler artikkelen der han introduserte ligninger, i dag kjent som Euler likningene, som kan beskrive væskedynamikk [31]. ... -
Rigorous estimates on mechanical balance laws in the Boussinesq–Peregrine equations
(Journal article; Peer reviewed, 2024)It is shown that the Boussinesq–Peregrine system, which describes long waves of small amplitude at the surface of an inviscid fluid with variable depth, admits a number of approximate conservation equations. Notably, this ... -

Rise and fall of sea ice production in the Arctic Ocean’s ice factories
(Journal article; Peer reviewed, 2022)The volume, extent and age of Arctic sea ice is in decline, yet winter sea ice production appears to have been increasing, despite Arctic warming being most intense during winter. Previous work suggests that further warming ... -
Risiko for spredning av flammer og røyk gjennom brannskiller ved endringer i bruk av sprinkler og røykkontroll i boligkvarter på petroleumsinnretninger.
(Master thesis, 2016-09-27)Målet med oppgaven har vært å undersøke hvordan endringer i bruk av sprinkler og brannspjeld i boligkvarter på petroleumsinnretninger, har påvirket risiko for spredning av flammer og røyk gjennom ventilasjonskanaler. ... -
Risk of Leakage versus Depth of Injection in Geological Storage
(Peer reviewed; Journal article, 2009-02)One of the outstanding challenges for large-scale CCS operations is to develop reliable quantitative risk assessments with a focus on leakage of both injected CO2 and displaced brine. A critical leakage pathway is associated ... -
Risk stratification in hypertrophic cardiomyopathy. Insights from genetic analysis and cardiopulmonary exercise testing
(Journal article; Peer reviewed, 2020)The role of genetic testing over the clinical and functional variables, including data from the cardiopulmonary exercise test (CPET), in the hypertrophic cardiomyopathy (HCM) risk stratification remains unclear. A retrospective ... -
Risks in Networked Computer Systems
(Doctoral thesis, 2008-09-24)Networked computer systems yield great value to businesses and governments, but also create risks. The eight papers in this thesis highlight vulnerabilities in computer systems that lead to security and privacy risks. A ... -
Riverine impact on future projections of marine primary production and carbon uptake
(Journal article; Peer reviewed, 2023)Riverine transport of nutrients and carbon from inland waters to the coastal and finally the open ocean alters marine primary production (PP) and carbon (C) uptake regionally and globally. So far, this process has not been ... -
RNA interference mediated knockdown of the KDEL receptor and COPB2 inhibits digestion and reproduction in the parasitic copepod Lepeophtheirus salmonis
(Peer reviewed; Journal article, 2014-04)Retrograde transport of proteins from the endoplasmic reticulum to the Golgi is an essential part of the secretory pathway that all newly synthesised secreted and membrane proteins in eukaryotic cells undergo. The aim of ... -
RNAi mediated myosuppressin deficiency affects muscle development and survival in the salmon louse (Lepeophtheirus salmonis)
(Peer reviewed; Journal article, 2019-05-06)Muscle activity is regulated by stimulatory and inhibitory neuropeptides allowing for contraction and relaxation. In Arthropods, one of the important myoinhibitors is Myosuppressin, belonging to FMRFamide-like peptides, ... -
RNAi-mediated treatment of two vertically transmitted rhabdovirus infecting the salmon louse (Lepeophtheirus salmonis)
(Peer reviewed; Journal article, 2017-10-25)Rhabdoviruses are a family of enveloped negative-sense single-stranded RNA viruses infecting a variety of hosts. Recently, two vertically transmitted salmon louse (Lepeophtheirus salmonis) rhabdoviruses (LsRV) have been ... -
