(Master thesis, 2015-05-13)Denne masteroppgaven har hatt som formål å modellere nedbrytningen av et utvalg sprøytemidler som ble testet på to norske forsøksfelt, i Stjørdal og Klepp med ulike klimatiske forhold og jordsmonn. For begge forsøksfelt ... -
New methodologies in sensory and consumer research with preadolescents to guide product development of healthy, child-centred food
(PhD Thesis;2021:89, Doctoral thesis, 2021)Childhood obesity is one of the most serious public health challenges of the twenty-first century (WHO, 2018). In this context, finding ways to make the healthier food choices the preferred ones, can be a valuable contribution ... -
Nitrogen-basert halosyklisering av 2-alkenylpyridiner
(Master thesis, 2017)Målet med oppgaven var å utforske de fundamentale aspektene ved jodsyklisering av 2-(alkenyl)pyridiner, og på den måten utvikle en metode for å syntetisere flersubstituerte alkaloider med bisykliske motiver slik de som er ... -
No man's land - An investigation of development of azole resistance in Aspergillus fumigatus within border zones surrounding golf fields.
(Master thesis, 2023)This project, conducted within the framework of the Navazole project, addressed the growing concern of azole-resistant Aspergillus fumigatus strains and their impact on humans, animals, and the environment. The aim was to ... -
Non-target and suspect characterisation of organic chemicals of emerging concern in air and biota
(PhD Thesis;2020:42, Doctoral thesis, 2020)Persistent organic pollutants (POPs) and other regulated organic chemicals are being monitored in the environment to evaluate the effectiveness of regulations and conventions, spatial and temporal trends as well as a ... -
Novel aspects of the ecophysiology of denitrifying bacteria and their roles in N2O emissions
(PhD Thesis;2017:91, Doctoral thesis, 2017)Environmental bacteria are in general limited by nutrient availability, and as the conditions fluctuate rapidly and unpredictably they must adapt or they will not thrive. This requires fast and adequate sensing and ... -
