(Peer reviewed; Journal article, 2023)Friction stir welding is a solid-state welding process used extensively for aluminium alloys. EN AW-1100 alloy is mostly used for its exceptional corrosion resistance, high ductility, high thermal and electrical conductivities, ... -
Parametric Optimization of a Power and Biomass to Liquid Process
(Chapter, 2019)In this study, a power & biomass to liquid process (PBtL) is optimized with respect to nine continuous design variables. These variables have great impact on the profitability of the process. A detailed process model is ... -
Parametric Study of Molten Aluminium Oxidation in Relation to Dross Formation at Laboratory and Industrial Scale
(Doctoral theses at NTNU, 2022:341, Doctoral thesis, 2022)Aluminium (Al) white dross, classified as a hazardous waste, is a heterogeneous mixture of metallic Al, oxides, and non-metallic compounds (NMC) originating from the primary production route of Al. Over the past few decades, ... -
Parametrisering av Kraftfelt for ReaxFF
(Master thesis, 2008)Denne oppgaven tar for seg innsamling av data for optimerte geometrier, energier og ladninger for molekylstrukturer av aluminium, indium (gruppe 3-atomer) og arsen (gruppe 5-atom), samt hydrogen. All informasjon er samlet ... -
Parametrisering av kraftfelt for ReaxFF med H, C, Si og Ge
(Master thesis, 2008)Sammenligning av DFT og ReaxFF beregninger for å kunne validere gjorte beregninger som input til paramtreisering av kraftfelt i ReaXFF for C, Si og Ge. -
Parametrization of a classical force field model (CT-PDI) for the calculation of molecular polarizablities
(Master thesis, 2023)To parametriseringer av en klassisk elektrostatisk modell for polariserbarheten er blitt gjennomført. Parametriseringene er gjennomført på et stort sett av små organiske molekyler, med mange vanlige funksjonelle grupper. ... -
Paraprobiotics and postbiotics of probiotic lactobacilli, their positive effects on the host and action mechanisms: A review
(Peer reviewed; Journal article, 2020)Lactobacilli comprise an important group of probiotics for both human and animals. The emerging concern regarding safety problems associated with live microbial cells is enhancing the interest in using cell components and ... -
Parasite escape through trophic specialization in a species flock
(Journal article, 2017)Adaptive radiation occurs when species diversify rapidly to occupy an array of ecological niches. As opportunities for parasite infection and transmission may greatly vary among these niches, adaptive radiation is expected ... -
Parasite prevalence increases with temperature in an avian metapopulation in northern Norway
(Peer reviewed; Journal article, 2019)Climate and weather conditions may have substantial effects on the ecology of both parasites and hosts in natural populations. The strength and shape of the effects of weather on parasites and hosts are likely to change ... -
Parasite–copepod interactions in Svalbard: diversity, host specificity, and seasonal patterns
(Peer reviewed; Journal article, 2022)Copepods of the genera Calanus and Pseudocalanus are important components of Arctic marine ecosystems. Despite the key roles of these zooplankters, little is known about the organisms they interact with most intimately, ... -
Part A: Investigations of Sodium-Graphite InteractionPart B: Structures and conformational Energies of 1,2- Dihaloethane and Silane AnaloguesPart C: Development of Ab Initio computational Methods based on non-orthogonal Slater Determinants
(Master thesis, 2011)Part A:Cathode wear is the limiting factor in the lifetime of electrolytic cells in aluminium production. One important reason for wear in carbon cathode materials is the penetration and diffusion of sodium from the melt, ... -
