Hair mineral levels as indicator of wildlife demographics?—a pilot study of muskoxen
(Peer reviewed; Journal article, 2022)The tight linkage between mineral status and health and demographics in animals is well documented. Mineral deficiencies have been coupled to population declines in wildlife. Current practices typically rely on liver, ... -
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 ... -
"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 ... -
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 ... -
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 ... -
Heat to Hydrogen by RED—Reviewing Membranes and Salts for the RED Heat Engine Concept
(Peer reviewed; Journal article, 2022)The Reverse electrodialysis heat engine (REDHE) combines a reverse electrodialysis stack for power generation with a thermal regeneration unit to restore the concentration difference of the salt solutions. Current approaches ... -
Heat transport through a solid-solid junction: the interface as an autonomous thermodynamic system
(Journal article; Peer reviewed, 2016-04)We perform computational experiments using nonequilibrium molecular dynamics simulations, showing that the interface between two solid materials can be described as an autonomous thermodynamic system. We verify the local ... -
The Heck reaction for synthesis of novel kinase inhibitors.
(Master thesis, 2015)Reaction conditions were investigated and developed for coupling of acrylates with different properties. A total of seven acrylic thienopyrimidines were synthesized, five of which were synthesized directly with the Heck ... -
