(Master thesis, 2011)I denne oppgaven er to vassdrag ved Svalbard studert gjennom en kort periode i juli/august 2009: Bayelva ved Ny-Ålesund og et vassdrag uten navn i Vintergata ved Sveagruva. Følgende parametre og metaller i oppløst og ... -
Assessing and managing environmental hazards of polymers: historical development, science advances and policy options
(Peer reviewed; Journal article, 2022)Polymers are the main constituents of many materials and products in our modern world. However, their environmental safety is not assessed with the same level of detail as done for non-polymeric chemical substances. Moreover, ... -
Assessing Root Development and Porosity in Ameliorated and Revegetated Bauxite Residue from Hydro-Alunorte, Brazil, through Digital Analysis of X-ray Micro Computed Tomography Images
(Master thesis, 2023)Bauksittrester (BR) er en svært alkalisk, saltholdig og sodisk rest av aluminaraffinerier med lite gjenbrukspotensial og er hovedsakelig tørrstablet i landdeponeringsområder. Erosjon av BR forårsaket av vind og regn utgjør ... -
Assessing the impact of CaO addition to pH, alkalinity and inorganic carbon in seawater with special focus on the kinetics
(Master thesis, 2019)Ocean Liming, OL er en foreslått teknologi der havet får mer alkalinitet fra tilførsel av CaO. Økt alkalinitet vil forsterke havets evne til å nøytralisere syre og dermed reversere havforsuring. Alkalinitet er sterkt knyttet ... -
Assessing the occurence of bisphenols and benzophenones in recirculating aquaculture systems in Norway
(Master thesis, 2023)De siste årene har landbaserte resirkulerende akvakultursystemer (RAS) blitt utviklet i håp om å møte utfordringer med sjøbaserte akvakulturanlegg. Vannet som brukes i RAS renses og resirkuleres. Dette kan by på nye ... -
Assessing the Persistence and Mobility of Organic Substances to Protect Freshwater Resources
(Peer reviewed; Journal article, 2022)Persistent and mobile organic substances are those with the highest propensity to be widely distributed in groundwater and thereby, when emitted at low-levels, to contaminate drinking water extraction points and freshwater ... -
Assessing the surface sites of the microporous materials H-ITQ-7 and H-Beta using FT-IR spectroscopy and various molecular probes
(Master thesis, 2010)The aim of the work presented in this thesis was to synthesize and assess the surface sites of two possible acid catalysts. The MTH reaction was used as a model reaction to evaluate the possibilities for the materials to ... -
Assessment of PEMFC Durability by Effluent Analysis
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:309, Doctoral thesis, 2011)A review of literature relevant for the understanding of chemical degradation in Polymer Electrolyte Membrane (PEM) systems was conducted. The proposed pathways to the formation of chemical species suspected of causing ... -

Association of urinary bisphenols during pregnancy with maternal, cord blood and childhood thyroid function
(Peer reviewed; Journal article, 2021)Background Most pregnant women are exposed to bisphenols, a group of chemicals that can interfere with various components of the thyroid system. Objectives To investigate the association of maternal urinary bisphenol ... -
Associations of maternal phthalate and bisphenol urine concentrations during pregnancy with childhood blood pressure in a population-based prospective cohort study
(Peer reviewed; Journal article, 2020)Objectives Fetal exposure to phthalates and bisphenols may lead to vascular developmental adaptations, which program later cardiovascular disease. We examined the associations of fetal exposure to phthalates and bisphenols ... -
Asymmetric Synthesis of 2-Phenylpyrrolidines for SAR Study of Thienopyrimidine-based EGFR Kinase Inhibitors
(Master thesis, 2018)The aim of this master s thesis was to carry out a preliminary structure-activity relationship (SAR) study of thieno[2,3-d]pyrimidines with racemic and enantioenriched 2-phenylpyrrolidine as a substituent on C-4. One ... -
