Forekomst av antibiokaresistens hos marine bakterier i Borgundfjorden
(Bachelor thesis, 2015)Denne studien tar for seg antibiotikapåvirkning og resistensutvikling hos marine bakterier ved sykehus utslipp. Prøver ble tatt fra et område nært renseanlegget og sammenlignet med prøver fra to referanseområder (områder ... -
Forekomst av antibiotikaresistens hos E. coli i akvatiske miljø i Trondheim
(Bachelor thesis, 2024)Antibiotikaresistens (AR) er en av nåtidens største globale helseutfordringer. Den voksende resistensen blant bakteriene truer medisinsk behandling og utviklingen omtales ofte som en stille pandemi. Spesielt fremveksten ... -
Forekomst av Listeria spp. i et nyetablert prosesseringsanlegg for laks - Vekst av Listeria monocytogenes og Listeria innocua på rustfritt stål, alene og i interaksjon med fire andre bakterieisolater
(Master thesis, 2019)Norsk oppdrettsnæring er verdensledende og i 2018 eksporterte Norge laks til en verdi av 67,8 milliarder kroner, som ble nok et rekordår. Kunden krever i et stadig mindre prosessert produkt og bruk av færre konserveringsmidler, ... -
Forekomst av Staphylococcus aureus på kunstgressbaner
(Bachelor thesis, 2020)Den første kunstgressbanen innen idrett på verdensbasis ble bygget på 1960-tallet, og siden har kunstgress utviklet seg gjennom fire generasjoner. Tredje generasjons (3G) kunstgress består av kunstgressfibre, sand og ... -
Forest and connectivity loss drive changes in movement behavior of bird species
(Peer reviewed; Journal article, 2020)In a rapidly changing world, it is important to understand how environmental modifications by humans affect species behavior. This is not a simple task, since we need to deal with a multitude of species and the different ... -
Forest management affects seasonal source-sink dynamics in a territorial, group-living bird
(Peer reviewed; Journal article, 2021)The persistence of wildlife populations is under threat as a consequence of human activities, which are degrading natural ecosystems. Commercial forestry is the greatest threat to biodiversity in boreal forests. Forestry ... -
Forhold mellom BaP og PAH4 i skjell og konsekvenser for gjeldende kostholdsråd i Norge. Uttalelse fra Faggruppen for forurensninger, naturlige toksiner og medisinrester
(VKM Report, Research report, 2011)Sjøbunnen i ulike områder langs norskekysten kan være forurenset med polysykliske aromatiske hydrokarboner (PAH) (”tjærestoffer”) på grunn av pågående eller tidligere industriell aktivitet, eller annen påvirkning. Flere ... -
Formation and characterization of β-and α-Silicon Carbide produced during Silicon/Ferrosilicon process
(Doctoral theses at NTNU;2020:252, Doctoral thesis, 2020)Silicon carbide (SiC) is one of the main intermediate compounds generated during primary silicon (Si) production in submerged arc furnaces. Carbon materials, either biomass-based (charcoal and wood chips) or based on fossil ... -
The Formation and Disintegration of Rafts from Different Aluminas and Fines
(Peer reviewed; Journal article, 2022)Raft formation is a frequently encountered problem during alumina feeding in the Hall-Héroult-process and will delay alumina from being dissolved into the melt. The mechanisms for the formation and disintegration of rafts ... -
Formation and evolution of the interfacial structure in Al/steel compound castings during solidification and heat treatment
(Peer reviewed; Journal article, 2020)In this work, Al7SiMg/steel compound castings were produced through a low-pressure die casting process. All steel inserts were galvanized, where half of them were flux-coated to further improve the wettability and remove ... -
Formation and growth of crystal defects in directionally solidified multicrystalline silicon for solar cells

Formation and growth of multiple, distinct ice lenses in frost heave
(Peer reviewed; Journal article, 2022)This paper presents a fully coupled thermo-hydro-mechanical (THM) modelwhich simulates frost heave in fully saturated soils. The model is able tosimulate the formation and growth of multiple distinct ice lenses. The ... -
Formation et destruction de NDELA dans des solutions de 30%m de MEA (Monoétha-nolamine) et de 50%m de DEA (Diéthanolamine)
(Journal article; Peer reviewed, 2014)The formation of nitrosodiethanolamine (NDELA) in a lab scale pilot was studied by feeding known amounts of nitrogen oxide and nitrogen dioxide into the gas entering the absorber. In the same pilot, the destruction by ... -
Formation mechanism and growth of MNbO3,M=K, Na by in situ X-ray diffraction
(Journal article; Peer reviewed, 2017)Hydrothermal synthesis is a well-established method to produce complex oxides, and is a potential interesting approach to synthesize stoichiometric lead-free piezoelectric K0.5Na0.5NbO3. Due to challenges in obtaining the ... -
Formation models for cosmic ray antinuclei
(Peer reviewed; Journal article, 2022)The expected low background of light antinuclei, such as antideuteron and antihelium-3, makes them ideal detection channels for exotic physics, such as dark matter annihilations. At the same time, their small binding ... -
