Halogenated Pyrrolopyrimidines with Low MIC on Staphylococcus aureus and Synergistic Effects with an Antimicrobial Peptide
(Peer reviewed; Journal article, 2022)Currently, there is a world-wide rise in antibiotic resistance causing burdens to individuals and public healthcare systems. At the same time drug development is lagging behind. Therefore, finding new ways of treating ... -
HAMLET forms annular oligomers when deposited with phoshpolipid monolayers
(Journal article; Peer reviewed, 2012)Recently, the anticancer activity of human α-lactalbumin made lethal to tumor cells (HAMLET) has been linked to its increased membrane affinity in vitro, at neutral pH, and ability to cause leakage relative to the inactive ... -
Handbook for the measurement of macrofungal functional traits: A start with basidiomycete wood fungi
(Journal article; Peer reviewed, 2018)Functional traits are widely recognized as a useful framework for testing mechanisms underlying species community assemblage patterns and ecosystem processes. Functional trait studies in the plant and animal literature ... -
Handling Discontinuities in Numerical ODE Methods
(Master thesis, 2021)Et vanlig ønske i mange typer arbeid er å finne den fremgangsmåten som gir best resultat uten å kreve for mye innsats. For eksempel så krever modellering av hvordan forurensende stoffer sprer seg i havet at man beregner ... -
"Hanging gardens" - comparing fauna communities in kelp farms and wild kelp forests
(Peer reviewed; Journal article, 2023)A growing need for food is causing increased interest for seaweed farming globally. This requires knowledge of the industry’s effects on the marine environment. We therefore aimed to explore the communities hosted by a ... -
Hardhetsreduksjon i varmepåvirket sone ved sveisereparasjon på utstyr i drift
(Bachelor thesis, 2020)Denne rapporten tar for seg identifisering og testing av en mulig metode å gjennomføre sveisereparasjoner av korrosjonsskader på utstyr i drift på olje- og gassanlegg. Eksempler på slikt utstyr er rør og tanker. Bakgrunnen ... -
Hardness and Microstructure for Ge-Containing Al-Mg-Si-Cu alloys
(Master thesis, 2012)Four different Al-Mg-Si-Cu-Ge alloys with 0.002--0.037 at.\% germanium were heat treated to the T6 condition and over-aged at 250$^{\circ}$C for up to 100 hours. The hardness was tested during the over-ageing and there ... -
Harnessing thermoelectric power from transient heat sources: Waste heat recovery from silicon production
(Journal article; Peer reviewed, 2017)Thermoelectric generators (TEGs) are compact and robust devices for converting heat into electrical power. In this work, we investigate the response of a bismuth-telluride based TEG to the transient environment of a silicon ... -
Harskningsproblematikk i brød av linfrø
(Bachelor thesis, 2022)Denne bacheloroppgaven er et samarbeid med Linbakst, der harskningsforløpet i linfrøbrød ble undersøkt. Problemstillingen var å se om tilsetning av ulike antioksidanter vil redusere dannelsen av harskningsprodukter. For å ... -
Hartree-Fock and Density Functional Theory methods used for Molecular Geometry Optimization
(Bachelor thesis, 2023)I denne oppgaven undersøkes Hartree-Fock og tetthetsfunksjonal teori (DFT) for bruk i geometrioptimalisering. Teorien bak Hartree-Fock og DFT er beskrevet grundig, og et uttrykk for molekylær gradient er utledet for ... -
Harvest-induced phenotypic selection in an island population of moose, Alces alces
(Journal article; Peer reviewed, 2016)Empirical evidence strongly indicates that human exploitation has frequently led to rapid evolutionary changes in wild populations, yet the mechanisms involved are often poorly understood. Here, we applied a recently ... -
Harvesting can stabilise population fluctuations and buffer the impacts of extreme climatic events
(Peer reviewed; Journal article, 2022)Harvesting can magnify the destabilising effects of environmental perturbations on population dynamics and, thereby, increase extinction risk. However, population-dynamic theory predicts that impacts of harvesting depend ... -
Hawk models, hawk mimics, and antipredator behavior of prey
(Journal article; Peer reviewed, 2015)Prey typically respond to potential predators by taking flight. This results in an optimal flight initiation distance (FID) at which the risk of remaining and the cost of flight are equal. Thus, FID is strongly negatively ... -
Hazard and Operability Study by Utilizing Hybrid Automata
(Master thesis, 2014)The following thesis is the end of a five year master program at the Norwegian University of Science and Technology, as part of the process eng. group at the institute of chemical engineering. Supervisor for the thesis has ... -
Head in the clouds, feet on the ground: how transdisciplinary learning can foster transformative change—insights from a summer school
(Peer reviewed; Journal article, 2023)There is a pressing need for transformative change, with a vision of long-term human well-being within planetary boundaries. The lack of progress—despite increasing awareness and action—illustrates how challenging it is ... -
Head-On Beam-Beam Interactions in High-Energy Hadron Colliders - GPU-Powered Modelling of Nonlinear Effects
(Master thesis, 2017)The performance of high-energy circular hadron colliders, as the Large Hadron Collider, is limited by beam-beam interactions. The strength of the beam-beam interactions will be higher after the upgrade to the High-Luminosity ... -
Heading for the hills: Risk avoidance drives den site selection in African wild dogs
(Journal article; Peer reviewed, 2014)Compared to their main competitors, African wild dogs (Lycaon pictus) have inferior competitive abilities and interspecific competition is a serious fitness-limiting factor. Lions (Panthera leo) are the dominant large ... -
Health-Aware Control of a Subsea Compression System
(Master thesis, 2018)Subsea processing technology is enabling production from oil and gas fields with larger water depths, longer tie-back distances and harsher climate conditions. Although moving production and processing facilities to the ... -
Heart rate and swimming activity as indicators of post-surgical recovery time of Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2021)Background Fish telemetry using electronic transmitter or data storage tags has become a common method for studying free-swimming fish both in the wild and in aquaculture. However, fish used in telemetry studies must be ... -
