Using Localized Molecular Orbitals in the Multi-level Coupled Cluster Approach
(Master thesis, 2016)In multi-level coupled cluster theory local orbitals have traditionally been generated us- ing Cholesky decomposition of the Hartree-Fock density matrix. Orbitals obtained through Cholesky decomposition are not very local ... -
Using Material Flow Analysis (MFA) to generate the evidence on plastic waste management from commercial fishing gears in Norway.
(Journal article; Peer reviewed, 2019)Plastic debris is an ever-growing concern adversely affecting the coastal and marine ecosystem. Among marine plastic waste, a particularly troublesome waste fraction is Abandoned, Lost or Discarded Fishing Gears (ALDFG) ... -
Using morphology and DNA barcoding to assess species diversity within the isopod genera Jaera Leach, 1814, Janira Leach, 1814 and Idotea Fabricius, 1798 in Norway
(Master thesis, 2021)Foreningen av morfologiske undersøkelser og DNA strekkoding, vil for mange regnes som de mest sentrale metodene i moderne studier om biodiversitet. Sammen har disse metodene stor kapasitet til å gi ny kunnskap og innsikt ... -
Using Photon Entanglement as a Fundamental Resource in Experimental Physics
(Master thesis, 2019)I denne masteroppgaven beskriver jeg to ulike eksperimenter relatert til bruken av sammenfiltrede fotonpar for metrologi og kvantenøkkeldistribusjon. Innenfor metrologi undersøkes et oppsett for å synkronisere klokker ... -
Using PyRETIS to study electron transfer reactions between Ru(II)/Ru(III) in an aqueous solution
(Master thesis, 2022)I denne avhandlingen ble ab initio molecular dynamics-simuleringer (AIMD) av elektron selvutvekslingsreaksjonen mellom Ru(II) og Ru(III) i en vandig løsning utført sammen med "rare-event path sampling" metoden RETIS fra ... -
Using renowned chefs for VeriTaste™ as a sensory method analysis in food products – A comparison of Atlantic salmon stored in refrigerated seawater and on ice
(Journal article; Peer reviewed, 2023) -
Using SeaFAST to Analyze the Rate of Change of Iron Release and Removal During the Decomposition of Planktonic Materials
(Master thesis, 2017)The cycling of iron in the ocean plays an important role within both the biological carbon pump and the nitrogen cycle. As much of primary production in the euphotic zone depends upon the internal recycling of iron, the ... -
Using STEM-DPC with a Conventional ADF Detector to Explore FIB Patterned Artificial Spin Ice Structures in Permalloy
(Master thesis, 2023)Vi befinner oss midt i en bemerkelsesverdig teknologisk revolusjon, der utviklingen innenfor områder som kunstig intelligens, robotikk og informasjonsteknologi er enorm. Som følge av dette er det et stort behov for mer ... -
Using Surplus Heat to Pre-Heat Carbon Anodes for Aluminium Electrolysis
(Master thesis, 2019)Karbon anoder brukes opp i Hall-Héroult prosessen og må erstattes regelmessig. Når en ny anode blir plassert i aluminiumsovnen, vil badet umiddelbart fryse på undersiden av anoden og danne et fryst isolerende lag. Denne ... -
Using Tea Bag index to examine the effects of ditching in boreal peatlands
(Master thesis, 2021)Menneskelige inngrep har ofte dårlige konsekvenser for myrer, som oftest grunnet grøfting. Vi har studert hvordan grøfting påvirker nedbrytningsraten i det nærliggende området gjennom et transekt studie i en ombrotrof ... -
Using thiourea as source for electrochemical generation of metal sulfides
(Journal article; Peer reviewed, 2008) -
Utforsking av seleksjonsmarkørar og effekten av feittsyresyntaseinhibitorar på feittsyresyntese i Aurantiochytrium sp.
(Master thesis, 2019)Thraustochytridar er heterotrofe, marine protistar, som har blitt kommersielt interessante dei siste tiåra sidan dei har ein høg produksjon av docosahexaensyre (DHA), som er ei langkjeda fleirumetta omega-3 feittsyre ... -
Utherdbare bimetall materialer fremstilt ved skrueekstrudering: AA 6060/ren magnesium
(Master thesis, 2013)Skruekstrudering er en ny, innovativ prosess for å fremstille metaller. Prosessens store fortrinn er et relativt lav energiforbruk sammenliknet med tradisjonell ekstrudering, noe som i dagens energisamfunn er meget aktuelt. ... -
The Utilization of Bauxite Residue with a Calcite-Rich Bauxite Ore in the Pedersen Process for Iron and Alumina Extraction
(Peer reviewed; Journal article, 2021)Metallurgical grade alumina is produced worldwide through the well-known Bayer process, which unavoidably generates bauxite residue (BR, also known as red mud) in almost equal amounts to alumina. This study aims the ... -
Utilization of By-Products from Norwegian Spring Spawning Herring for Human Consumption
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:317, Doctoral thesis, 2013)There is an increasing demand for oils and proteins of marine origin for human consumption. Marine lipids are rich in the long chain omega-3 polyunsaturated fatty acids, especially eicosapentaenoic acid (EPA; C20:5 n-3) ... -
Utilization of egg-laying hens (Gallus Gallus domesticus) for production of ingredients for human consumption and animal feed
(Journal article; Peer reviewed, 2020)Background In Norway, 3 million discarded egg-laying hens are destructed annually, which equals 1500 tons pure hen meat. Due to the slaughter methods used, this raw material is handled as a high-risk waste, while in reality ... -
Utilization of excess nutrients from land-based aquaculture facilities by Hediste diversicolor (O.F. Müller, 1776) - Production of polychaete biomass and its potential use in fish feed
(Master thesis, 2017)Farming of Atlantic salmon (Salmo salar) is highly dependent on marine resources such as fish meal and fish oil. In Norway, supply of high quality raw materials and control of waste discharges from aquaculture are factors ... -
