Crack localization and the interplay between stress enhancement and thermal noise
(Peer reviewed; Journal article, 2021)We study the competition between thermal fluctuations and stress enhancement in the failure process of a disordered system by using a local load sharing fiber bundle model. The thermal noise is introduced by defining a ... -
Cratering behaviour and faecal C:N ratio in relation to seasonal snow-pack characteristics in a High-Arctic ungulate
(Journal article; Peer reviewed, 2017)Snow and ice determine winter forage availability for Arctic herbivores. Winter precipitation is anticipated to increase, and icing following warm spells and rain-on-snow (ROS) are likely to become more frequent. While ... -
Creating a Gene Expression Cassette for the Cyanobacterium Synechococcus sp. PCC 7002 - And Using it to Replace the Endogenous Hydrogenase
(Master thesis, 2015)Eukaryotic algae and cyanobacteria are a promising source of future biofuels, having many important advantages over 1st and 2nd generation biofuels. Synechococcus sp. PCC7002 is the fastest growing oxygen producing ... -
Creating a machine learning based surrogate model for modelling of a carbon capture plant
(Master thesis, 2022)Dagens metoder for å gjøre en parameterstudie av et karbonfangstanlegg er ofte en treg prosess som krever mye innsats og manuell input. For å gjøre denne pros- essen mindre arbeidskrevende ble et neuralt nettverk konstruert ... -
Creation and preliminary characterization of LHCR6/LHCR8 single and double knockout strains of the diatom Phaeodactylum tricornutum
(Master thesis, 2021)Kiselalger er en gruppe eukaryote mikroalger som er utbredt i de fleste akvatiske habitater. Æren for den betydelige økologiske suksessen til denne gruppen kan i stor grad tildeles den eksepsjonelle lystilpasning-evnen ... -
Creation of activity of bc1 complex kinase (abc1k) knockout mutants to investigate their role in light acclimation in the marine diatom Phaeodactylum tricornutum
(Master thesis, 2022)Kiselalger er encellede fotosyntetiske mikroalger med en viktig økologisk rolle på grunn av deres bidrag til primærproduksjonen. Marine kiselalger kan oppleve raske endringer i lysintensiteten når de befinner seg i turbulent ... -
Creation of entangled atomic states by an analogue of the Dynamical Casimir effect
(Journal article; Peer reviewed, 2018)If the boundary conditions of the quantum vacuum are changed in time, quantum field theory predicts that real, observable particles can be created in the initially empty modes. Here, we realize this effect by changing the ... -
Creation of Eternal Cells through FACS-assisted Genomic Engineering of Bacillus subtilis
(Master thesis, 2023)Bacillus subtilis er en modellorganisme innenfor bioteknologi som har blitt grundig studert over flere tiår og blitt brukt i en rekke industrielle sammenhenger. Bakterien har evnen til å gjennomgå sporedannelse i tillegg ... -
Creation of Phaeodactylum tricornutum mutant strains with truncated light harvesting antennas through CRISPR/Cas9 mediated knockout of members of the CpSRP pathway
(Master thesis, 2017)Production of marine fatty acids by diatom cultivation has previously been proposed as a way to create a new source of omega-3 to be used in aquafeed. However, low photosynthetic productivity of diatoms in mass cultivation ... -
Creep deformation of an additively manufactured nickel-based superalloy
(Master thesis, 2022)To versjoner av en nikkelbasert superlegering ble produsert med additiv tilvirkning og karakterisert etter sigetesting med SEM og atomprobetomografi. De to legeringene ble kalt CB og C da hovedforskjellen i mellom dem var ... -
Creep failure in a threshold-activated dynamics: Role of temperature during a subcritical loading
(Peer reviewed; Journal article, 2020)Creep is a time-dependent deformation of solids at relatively low stresses, leading to the breakdown with time. Here we propose a simple model for creep failure of disordered solids in which temperature and stress are ... -
Crevice corrosion of AISI 316L and 22Cr - the effect of temperature, chloride concentration, pH and oxygen content
(Master thesis, 2020)Korrosjonsresistente legeringer, som for eksempel rustfrie stål, blir ofte brukt i offshore-installasjoner på grunn av deres høye motstand mot generell korrosjon. Rustfrie stål er imidlertid utsatt for lokal korrosjon, som ... -
CRISPR-Cas Based Genome Editing for in-vivo Biopolymer Engineering in Paenibacillus polymyxa
(Master thesis, 2020)Mange bakterier har evnen til å produsere eksopolysakkarider. Disse polysakkaridene har viktige funksjoner for cellen, men har også vist lovende egenskaper for bruk i industrien. Det eksisterer mange forskjellige typer ... -
