Isolation of thermophilic enzyme-producing Parageobacillus bacteria from chipped woody waste
(Journal article; Peer reviewed, 2019)The morphological and biochemical properties were investigated for 18 types of thermophilic bacteria isolated from a woody-chip pile at a wood processing plant in Northern Russia. Genetic fingerprinting and 16S rRNA ... -
Isolation, Characterization and Prediction of Calcium Naphthenates in High Acid Crude Oils
(Master thesis, 2015)Calcium naphthenates in crude oil causes operational problems in refineries and lowers the market price for oil production companies. This Master s thesis aims to study the naphthenic acids who form calcium naphthenates ... -
Isolering og karakterisering av helsefremmende lipider fra mikroalger
(Master thesis, 2016)Langkjedete omega-3 fettsyrer, som EPA (eikosapentaensyre) og DHA (dokosahexaensyre), er viktige for et balansert kosthold og kan gi gode helsemessige fordeler. Per dags dato får de fleste for lite av disse fettsyrene ... -
Isothermal and non-isothermal annealing of cold-rolled Al-Mn-Fe-Si alloys with different microchemistry states
(Journal article, 2014)Investigation of the microstructural evolution of Al-Mn-Fe-Si alloys during annealing after cold rolling has been carried out. The effect of microchemistry state in terms of Mn in solid solution, constituents, size and ... -
Isothermal annealing of cold-rolled Al−Mn−Fe−Si alloy with different microchemistry states
(Journal article, 2014)Microstructural evolution of a cold-rolled Al–Mn–Fe–Si alloy during annealing was studied. Except the as-cast variant, two other different homogenizations were considered, one gave a high density of fine dispersiods providing ... -
Isothermal Hydrogen Reduction of a Lime-Added Bauxite Residue Agglomerate at Elevated Temperatures for Iron and Alumina Recovery
(Peer reviewed; Journal article, 2022)The hydrogen reduction of bauxite residue lime pellets at elevated temperatures was carried out to recover iron and alumina from the bauxite residue in a new process route. Prior to the H2 reduction, oxide pellets were ... -
Isothermal Reduction of Nchwaning Manganese Ore in CO/CO2/H2 Atmospheres
(Journal article, 2021)In the industrial production of manganese ferroalloys, incomplete pre-reduction of higher manganese- and iron oxides in the furnace causes an excess consumption of carbon and energy. Pre-treatment of the manganese raw ... -
Iterative sub-network component analysis enables reconstruction of large scale genetic networks
(Journal article; Peer reviewed, 2015)Background: Network component analysis (NCA) became a popular tool to understand complex regulatory networks. The method uses high-throughput gene expression data and a priori topology to reconstruct transcription factor ... -

“It’s not uncomplicated to say you simply cannot do it like this anymore” – a study of the Norwegian whitefish industry and the potential for improved utilization of rest raw materials
(Doctoral theses at NTNU;2021:387, Doctoral thesis, 2021)The Norwegian whitefish industry has long traditions and constitutes an important part of both economy and food production. Whitefish is a collective term for several lean fish species, the most important being cod (Gadus ... -
Ivaretagelse av ville pollinatorer og planter tilknyttet kulturlandskapet i byutviklingen. Oppsummering av forskningsprosjektet BE(E) DIVERSE
(NIBIO Rapport, Research report, 2023)Det er en global nedgang av ville pollinatorer, og hovedårsaken til dette er at leveområdene deres er under press og går tapt på grunn av urbanisering og andre arealendringer. I BE(E) DIVERSE prosjektet har vi derfor studert ... -
Jakt på kortnebbgås (Anser brachyrhynchus) under høsttrekket i Nord-Trøndelag: Jaktens utførelse, sammensetning av utbyttet og mulige konsekvenser for den Svalbard-hekkende bestanden
(Master thesis, 2013)SammendragSvalbards hekkebestand av kortnebbgås, som trekker gjennom Norge til overvintring i Danmark, Nederland og Belgia, har økt markant de siste 30 årene fra omkring 20 000 individer på 1980-tallet til omkring 80 000 ... -
Jamming-flow transitions of confined self-propelled rods
(Master thesis, 2021)Denne oppgaven presenterer en numerisk undersøkelse av egenskapene til en hybridmodell av selvdrevne stav-aktige partikler i 2D som vekselvirker via apolar vinkeltilpasning og myk frastøtning. Såkalte aktive partikler ... -
Janthinobacterium Strains Isolated from Rearing Systems for Atlantic Salmon Fry Growth Characteristics, Violacein Production and Evolution of the Violacein Operon
(Master thesis, 2021)Janthinobacterium lividum er tidligere isolert fra amfibieskinn og menneskehud. Arten er kjent for å produsere det lilla pigmentet violacein, som har vist seg å ha antifungale, antibakterielle, antivirale og antitumorale ... -
Japanese quail (Coturnix japonica) liver and thyroid gland histopathology as a result of in ovo exposure to the flame retardants tris(1,3-dichloro-2-propyl) phosphate and Dechlorane Plus
(Journal article; Peer reviewed, 2017)Japanese quails (Coturnix japonica) were exposed in ovo to tris(1,3-dichloro-2-propyl) phosphate (TDCIPP; 500 ng/µl), Dechlorane Plus (DP; 500 ng/µl), or a 1:1 mixture of these two to investigate the effects on liver and ... -
Jellyfishing in Europe: Current status, knowledge gaps, and future directions towards a sustainable practice
(Peer reviewed; Journal article, 2021)Jellyfish are often described as a nuisance species, but as our understanding shifts to more ecosystem-based conceptions, they are also recognized as both important components of marine ecosystems and a resource for humans. ... -
Jet fuel range hydrocarbon production from propanal: Mechanistic insights into active site requirement of a dual-bed catalyst
