Effect of Siderophore on Iron Availability in a Diatom and a Dinoflagellate Species: Contrasting Response in Associated Bacteria
(Journal article; Peer reviewed, 2018)Organic ligands play a key role controlling trace metal bioavailability in the world's oceans, yet the species-specific requirements determining whether certain iron forms can be metabolized largely remain unclear. ... -
Effect of Surface Chemistry and Physical Properties of Carbon Nanotubes on the Adsorption of Polycyclic Aromatic Hydrocarbons in Aqueous Solutions
(Master thesis, 2013)Adsorption behavior of seven different carbon nanotubes (CNTs) towards polycyclic aromatic hydrocarbons (PAHs) was studied in moderately hard reconstituted water (MHRW) with and without dissolved natural organic matter ... -
Effect of temperature on the metabolism, behaviourand oxygen requirements of Sparus aurata
(Journal article; Peer reviewed, 2015)We investigated the effect of temperature on the limiting oxygen saturation (LOS) of gilthead sea bream Sparus aurata. This threshold was defined as the % O2 saturation where fish no longer upheld their routine metabolic ... -
Effect of temperature on the settling rate, survival, ingestion rate and biochemical composition of the polyp stages of A. aurita
(Master thesis, 2020)Store manetansamlinger kjent som manetoppblomstringer er forventet å øke som en følge av menneskeskapte påvirkninger. Oppblomstringene er kjent for å føre til økonomiske, og potensielt økologiske, skader. GoJelly er et EU ... -
Effect of the Manufacturing Process on the Microbiota, Organoleptic Properties and Volatilome of Three Salmon-Based Products
(Peer reviewed; Journal article, 2021)Lightly preserved seafood products, such as cold-smoked fish and fish gravlax, are traditionally consumed in Europe and are of considerable economic importance. This work aimed to compare three products that were obtained ... -
Effect of working position and cold environment on muscle activation level and fatigue in the upper limb during manual work tasks
(Peer reviewed; Journal article, 2020)Several occupational groups are exposed to periods of low ambient temperatures while performing manual work tasks outdoors. Work tasks typically include heavy lifting, tool handling, and overhead work. This study evaluated ... -
Effect-Directed Analysis Based on Transthyretin Binding Activity of Per- and Polyfluoroalkyl Substances in a Contaminated Sediment Extract
(Peer reviewed; Journal article, 2023)Only a fraction of the total number of per- and polyfluoroalkyl substances (PFAS) are monitored on a routine basis using targeted chemical analyses. We report on an approach toward identifying bioactive substances in ... -
Effective size of density dependent populations in fluctuating environments
(Doctoral theses at NTNU;2017:156, Doctoral thesis, 2017)Knowledge of the effective size of populations, Ne, and the ratio of effective population size to the size of the mature population Ne/N, provide important information of the genetic diversity and fitness of populations. ... -
Effects and recovery of larvae of the cold-water coral Lophelia pertusa (Desmophyllum pertusum) exposed to suspended bentonite, barite and drill cuttings
(Peer reviewed; Journal article, 2020)Fossil fuel drilling operations create sediment plumes and release waste materials into the ocean. These operations sometimes occur close to sensitive marine ecosystems, such as cold-water corals. While there have been ... -
Effects of 8 weeks of exergaming on cardiorespiratory fitness and physical activity levels in inactive people.
(Master thesis, 2020)Sammendrag Introduksjon: Fysisk aktivitet kan redusere risikoen for mange ulike sykdommer, eksempelvis kardiovaskulære sykdommer, kreft og diabetes type 2. Likevel er aktivitetsnivået i verdens befolkning synkende. Både ... -
Effects of a complex contaminant mixture on thyroid hormones in breeding hooded seal mothers and their pups
(Journal article; Peer reviewed, 2018)There is a general lack of information on the possible effects of perfluoroalkyl substances (PFASs) on thyroid hormones (THs) in wildlife species. The effects of PFASs, which are known endocrine disruptors, on the TH ... -
Effects of Ammonia and Organic Ligands to Cadmium (Cd) Toxicity on Marine Phytoplankton
(Master thesis, 2012)The effects of ammonia to Cd toxicity on marine phytoplankton have been studied. The phytoplankton biomass was significantly increased at higher ammonia flux after high Cd level exposure, which indicated high ammonia ... -
Effects of an Offshore Eind Farm (OFW) on the Common Shore Crab Carcinus maenas: Tagging Pilot Experiments in the Lillegrund Offshore Wind Farm (Sweden).
(Journal article; Peer reviewed, 2016)Worldwide growth of offshore renewable energy production will provide marine organisms with new hard substrate for colonization in terms of artificial reefs. The artificial reef effect is important when planning offshore ... -
