Chatbot Generation for Open Data Accessibility
(Master thesis, 2023-11-20)Open data, despite its availability, often remains inaccessible to the average person due to complex data formats and technical barriers. This challenge hinders the realization of open data’s transformative potential. ... -
Chelating agents for diluted geothermal brine reinjection
(Journal article; Peer reviewed, 2022)“Blue energy” could be produced by exploiting the large salinity gradient between geothermal fluids and freshwater through a SaltPower system. This study is an attempt to select the most favorable chemicals to avoid ... -
Chemical characterization of 21 species of marine macroalgae common in Norwegian waters: benefits of and limitations to their potential use in food and feed
(Peer reviewed; Journal article, 2018-01-18)BACKGROUND: In the past few years, much effort has been invested into developing a new blue economy based on harvesting, cultivating and processing marine macroalgae in Norway. Macroalgae have high potential for a wide ... -
The chemical composition of two seaweed flies (Coelopa frigida and Coelopa pilipes) reared in the laboratory
(Peer reviewed; Journal article, 2018-05-29)Two species of seaweed flies, Coelopa frigida and Coelopa pilipes, were reared in the laboratory and their larvae were sampled for composition of amino acids, fatty acids and elements. The larvae were grown on two different ... -
The chemical defensome of five model teleost fish
(Journal article; Peer reviewed, 2021)How an organism copes with chemicals is largely determined by the genes and proteins that collectively function to defend against, detoxify and eliminate chemical stressors. This integrative network includes receptors and ... -
Chemical inhibition of hydrogen explosions using dry water and propane
(Master thesis, 2024-06-03)This research project characterises an experimental investigation with the aim of finding the laminar burning velocity of hydrogen-air explosion, inhibit the reactive compound using dry water and hydrocarbon (propane) and, ... -
Chemical Insights from Carbon 1s Photoelectron Spectroscopy and Theoretical Modeling
(Doctoral thesis, 2007-08-31)Inner-shell ionization energies provide local probes of the charge distribution in molecules and of the ability of a molecule to accept charge at specific sites. As such, core-ionization energies are related to and may ... -
Chemical Properties of Alkenes and Alkynes from Carbon 1s Photoelectron Spectroscopy and Theory
(Doctoral thesis, 2013-02-27)The field of electron spectroscopy has evolved extensively the last couple of decades. On one hand, the technology at the synchrotron radiation facilities and of electron analyzers has improved, providing experimental data ... -
Chemical reactivity of methylbenzenes from core-photoelectron spectroscopy and theory
(Master thesis, 2000) -
Chemical studies of cytotoxic natural products from toxic and edible plant sources
(Doctoral thesis, 2024-04-19)Denne doktorgradsavhandlingen fokuserer på isolering og identifikasjon av naturstoffer fra fire utvalgte planter, hvor den cytotoksiske aktiviteten til nyoppdagede og interessante naturstoffer ble testet på blodkreftceller ... -
Chemical variations in Quercus pollen as a tool for taxonomic identification: Implications for long-term ecological and biogeographical research
(Journal article; Peer reviewed, 2020)Aim Fossil pollen is an important tool for understanding biogeographical patterns in the past, but the taxonomic resolution of the fossil‐pollen record may be limited to genus or even family level. Chemical analysis of ... -
Chemical weathering on Eldsfjellet, Meland municipality, western Norway
(Master thesis, 2012-11-27)The Subject of this master thesis was to define the chemical weathering processes, create a weathering chain from sink to source and to evaluate the degree of weathering on Eldsfjellet, Meland municipality in western Norway. ... -
ChemicalDrift 1.0: an open-source Lagrangian chemical-fate and transport model for organic aquatic pollutants
(Journal article; Peer reviewed, 2023)A new model for transport and fate of chemicals in the aquatic environment is presented. The tool, named ChemicalDrift, is integrated into the open-source Lagrangian framework OpenDrift and is hereby presented for organic ... -
Chemometric Approaches for the Validation and Optimization of a LC-MS/MS Method for the Analysis of Phenanthrene Metabolites in Atlantic Haddock Embryo
(Master thesis, 2023-04-27)The release of oil and petroleum products into the environment has long been a cause for concern due to its toxic effects on marine species. In particular, the Atlantic haddock has shown enhanced sensitivity towards the ... -
A chemosynthetic weed: the tubeworm Sclerolinum contortum is a bipolar, cosmopolitan species
(Peer reviewed; Journal article, 2015-12-14)Background Sclerolinum (Annelida: Siboglinidae) is a genus of small, wiry deep-sea tubeworms that depend on an endosymbiosis with chemosynthetic bacteria for their nutrition, notable for their ability to colonise a multitude ... -

Chironomids, temperature and numerical models: a reply to Seppälä
(Peer reviewed; Journal article, 2001)We reply to comments by Seppälä (2001) concerning the suitability of the surface-water temperature measurements and mean July air temperature estimates used by Olanderet al. (1999) to derive quantitative chironomid-temperature ... -
Chitin synthases are critical for reproduction, molting, and digestion in the salmon louse (Lepeophtheirus salmonis)
(Journal article; Peer reviewed, 2021-01-13)Chitin synthase (CHS) is a large transmembrane enzyme that polymerizes Uridine diphosphate N-acetylglucosamine into chitin. The genomes of insects often encode two chitin synthases, CHS1 and CHS2. Their functional roles ... -
