The Impact of Water on Ru-Catalyzed Olefin Metathesis: Potent Deactivating Effects Even at Low Water Concentrations
(Journal article; Peer reviewed, 2021)Ruthenium catalysts for olefin metathesis are widely viewed as water-tolerant. Evidence is presented, however, that even low concentrations of water cause catalyst decomposition, severely degrading yields. Of 11 catalysts ... -
Impacts of Atlantic multi-decadal variability on the Indo-Pacific and Northern Hemisphere climate
(Doctoral thesis, 2016-06-03)Earlier studies have shown that Atlantic multi-decadal variability (AMY) can impact climate variability globally. However the instrumental records are short compared to the timescale of AMY, and mechanisms for these impacts ... -
Impacts of climate change on Blue Nile flows using bias-corrected GCM scenarios
(Peer reviewed; Journal article, 2009)This study analyses the output of 17 general circulation models (GCMs) included in the 4th IPCC assessment report. Downscaled precipitation and potential (reference crop) evapotranspiration (PET) scenarios for the 2081– ... -
Impacts of Covid-19 on Norwegian salmon exports: A firm-level analysis
(Journal article; Peer reviewed, 2022)A rapidly growing literature investigates how the recent Covid-19 pandemic has affected international seafood trade along multiple dimensions, creating opportunities as well as challenges. This suggests that many of the ... -
Impacts of Greenland Block Location on Clouds and Surface Energy Fluxes over the Greenland Ice Sheet
(Journal article; Peer reviewed, 2020)Clouds and blocking activity have been implicated as causes of increased Greenland Ice Sheet (GrIS) melt in the 21st century. Although Greenland blocks (i.e., long-lasting, mostly stationary anticyclones) generally reduce ... -
Impacts of Ionospheric Ions on Magnetic Reconnection and Earth's Magnetosphere Dynamics
(Journal article; Peer reviewed, 2021)Ionospheric ions (mainly H+, He+, and O+) escape from the ionosphere and populate the Earth's magnetosphere. Their thermal energies are usually low when they first escape the ionosphere, typically a few electron volt to ... -
Impacts of Peak-Flow Events on Hyporheic Denitrification Potential
(Journal article; Peer reviewed, 2022)Subsurface flows, particularly hyporheic exchange fluxes, driven by streambed topography, permeability, channel gradient and dynamic flow conditions provide prominent ecological services such as nitrate removal from streams ... -
Impacts of predation by Eurasian otters on Atlantic salmon in two Norwegian rivers
(Journal article; Peer reviewed, 2023)1. The return of the Eurasian otter (Lutra lutra) to western Norway has sparked human–predator conflicts because otters prey on vulnerable Atlantic salmon (Salmo salar) populations. Although predation may not be the ultimate ... -
Impacts of seismic resolution on fault interpretation: Insights from seismic modelling
(Journal article; Peer reviewed, 2021)Seismic mapping of subsurface faults is hampered by factors such as seismic resolution, velocity control for depth conversion and human bias. Here, we explore the challenges and pitfalls related to interpreting normal ... -
Impacts of small-scale faults on continental to coastal plain deposition: Evidence from the Realgrunnen Subgroup in the Goliat field, southwest Barents Sea, Norway
(Peer reviewed; Journal article, 2018-08)In this study we synthesise sedimentological, fault, and Amplitude Versus Angle (AVA) analysis and propose that the Fruholmen and Tubåen formations (Realgrunnen Subgroup) are syn-kinematic deposits that record a previously ... -
Impacts of the autumn Arctic sea ice on the intraseasonal reversal of the winter Siberian high
(Peer reviewed; Journal article, 2019-02)During 1979–2015, the intensity of the Siberian high (SH) in November and December–January (DJ) is frequently shown to have an out-of-phase relationship, which is accompanied by opposite surface air temperature and circulation ... -
Impacts of the extratropical North Pacific on boreal summer Arctic circulation
(Journal article; Peer reviewed, 2023)A distinct characteristic of the Arctic summer atmospheric circulation is the anomalous anticyclonic circulation centered over the Arctic Ocean associated with significant Arctic warming. Previous studies have related the ... -
Impacts of UV Irradiance and Medium-Energy Electron Precipitation on the North Atlantic Oscillation during the 11-Year Solar Cycle
(Journal article; Peer reviewed, 2021)Observational studies suggest that part of the North Atlantic Oscillation (NAO) variability may be attributed to the spectral ultra-violet (UV) irradiance variations associated to the 11-year solar cycle. The observed ... -
Impacts on carbon budgets of increased use og Norwegian forest resources for energy
(Master thesis, 2019-06-19)When forests are logged for heat and electricity production, emissions from burning of the biomass are not accounted for in national greenhouse gas reporting to the climate convention. This would have been correct if a ... -
Impacts on oil recovery from capillary pressure and capillary heterogeneities
(Doctoral thesis, 2008-06-02)This thesis summarises the findings made in NFR-funded project “Capillary Pressure and Capillary Heterogeneities”. The focus has been to determine the impact on oil recovery from wettability and fractures in carbonate ... -
Implementasjon av attributtbasert tilgangskontroll i elektroniske helsesystemer
(Master thesis, 2015-05-28)Tilgangskontroll er et av de viktigste temaene innenfor informasjonssikkerhet[10]. Sensitiv data bør bare kunne aksesseres av autoriserte brukere eller programmer. Denne oppgaven har som hovedmål å undersøke den nåværende ... -
Implementasjon av interrupt-styrd DMA-overføring på HLT-RORC
(Master thesis, 2005)På CERN i Geneve vert det bygd ein ny partikkelakselerator kalla LHC. Ein av dei fire hovuddetektorane i LHC vert kalla for ALICE. I ALICE-detektoren møtest akselererte blyion i høgenergetiske kollisjonar. Med desse ... -
Implementation and Evaluationof a Fire Risk Indication Model
(Master thesis, 2019-06-29)During the winter seasons there will often be a higher risk house fires due tothe dry climate as the result of cold weather. The fire department, and otherclients, would therefore have benefit of a fire risk indication ... -
