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 ... -
Use of industry 4.0 technologies to reduce and valorize seafood waste and by-products: A narrative review on current knowledge
(Peer reviewed; Journal article, 2023)Fish and other seafood products represent a valuable source of many nutrients and micronutrients for the human diet and contribute significantly to global food security. However, considerable amounts of seafood waste and ... -
Use of NMR spectroscopy in combination with pattern recognition techniques for elucidation of origin and adulteration of foodstuffs
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:114, Doctoral thesis, 2009)Consumers and food authorities are, to an increasing extent, concerned about factors such as the origin of food, how it is produced, and if it is healthy and safe. There are methods for general quality control to map the ... -
Use of Photocatalytically Active Supramolecular Organic–Inorganic Magnetic Composites as Efficient Route to Remove β-Lactam Antibiotics from Water
