Use of different imaging systems for ROV-based mapping of complex benthic habitats
(Master thesis, 2022)Denne studien bruker mini-ROV-er, små fjernstyrte kjøretøyer som bærer kameraer med forskjellige egenskaper som undervanns hyperspektral avbildning (UHI) og høy-definisjon (HD) rød, grønn og blå (RGB) kameraer for å kartlegge ... -
Use of digestive gland explant cultures from blue mussels (Mytilus edulis) to assess biomarker effects of single and co-exposure of environmental contaminants
(Master thesis, 2020)Urbanisering og økt sjøtrafikk rundt Tromsø øker presset på lokale marine økosystemer. Det er avgjørende å finne egnede metoder for å overvåke virkningene av menneskelige aktiviteter på havbestandene. Virvelløse dyr, som ... -
Use of fatty acid profiles to monitor the escapehistory of farmed Atlantic salmon
(Journal article; Peer reviewed, 2015)Farmed Atlantic salmon can escape from fish farms at various stages of their life, from juveniles to large mature fish. Escapees that enter rivers to spawn pose a threat to the genetic integrity of wild populations. ... -
The Use of Fe-26Si-9B Alloy as Phase Change Material in Si<inf>3</inf>N<inf>4</inf> Container
(Peer reviewed; Journal article, 2022)Fe-26Si-9B alloy was selected as a potential phase change material (PCM) to store energy at temperatures up to 1300 °C. A suitable refractory material is crucial to building a PCM container for Fe-26Si-9B alloy in thermal ... -
Use of H2 in Mn-Ferroalloy Production
(Chapter, 2023)The use of H2 as a reductant in the iron and steel industry is an obvious choice towards carbon neutrality. For pyrometallurgical processes like Mn and Si, H2 cannot be the only solution, as the stability of the oxides of ... -
Use of Homologous Recombination to Study Alginate Biosynthesis in Azotobacter vinelandii.
(Master thesis, 2021)Alginat er en lineær, anionisk biopolymer bestående av mannuronsyre (M) og guluronsyre (G). Polymeren har mange bruksområder innen industri og er særlig interessant på grunn av dens evne til å danne geler, en egenskap som ... -
The use of hydrogen as a potential reductant in the chromite smelting industry
(Peer reviewed; Journal article, 2022)The chromium (Cr) content of stainless steel originates from recycled scrap and/or ferrochrome (FeCr), which is mainly produced by the carbothermic reduction of chromite ore. Ever-increasing pressure on FeCr producers to ... -
