Dc Josephson Effect in Altermagnets
(Journal article; Peer reviewed, 2023)The ability of magnetic materials to modify superconductors is an active research area for possible applications in thermoelectricity, quantum sensing, and spintronics. We consider the fundamental properties of the Josephson ... -
De Første Stegene mot en Perturbasjonsteori for Små Systemer
(Master thesis, 2020)Tilstandsligninger (EOS) utviklet gjennom perturbasjonsteori er kjent i litteraturen og kan være et nyttig verktøy for å modellere væskeoppførsel. Selv om populære perturbasjonsteorier av f.eks. Barker-Henderson (BH) ... -
De-Icing Coatings Based on Solar Illumination
(Master thesis, 2023)Avising av overflater er viktig for ulike strukturer i kaldt klima, som veier, høyspentlinjer, vindmøller eller i luftfartsindustrien. Målet med dette arbeidet er å undersøke fabrikasjonsprosessen og karakterisere fire ... -
De-icing coatings based on solar illumination Preparation and characterization
(Master thesis, 2022)Målet med dette prosjektet har bestått av å lage og karakterisere et overflatebelegg som kan utnytte energien i solstråler til avising av vindmøller og andre installasjoner utsatt for isakkumulering. Belegget består av tre ... -

Deactivation of Co-Based Fischer−Tropsch Catalyst by Aerosol Deposition of Potassium Salts
(Journal article; Peer reviewed, 2018)A 20%Co/0.5%Re/γAl2O3 Fischer−Tropsch catalyst was poisoned by four potassium salts (KNO3, K2SO4, KCl, and K2CO3) using the aerosol deposition technique, depositing up to 3500 ppm K as solid particles. Standard characterization ... -
Deactivation of cobalt based Fischer-Tropsch synthesis catalysts
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:304, Doctoral thesis, 2011) -
A dead giveaway: Foraging vultures and other avian scavengers respond to auditory cues
(Peer reviewed; Journal article, 2020)Carrion represents an unpredictable and widely distributed primary food source for vultures and other avian scavengers. Avian scavengers in African savanna ecosystems are reported to rely exclusively on visual stimuli to ... -
Dead wood profile of a semi-natural boreal forest – implications for sampling
(Journal article; Peer reviewed, 2019)Dead wood profile of a forest is a useful tool for describing forest characteristics and assessing forest disturbance history. Nevertheless, there are few studies on dead wood profiles, including both coarse and fine dead ... -
Dealing with different conceptions of pollution in the Gene Regulation Knowledge Commons
(Peer reviewed; Journal article, 2022)Current research of gene regulatory mechanisms is increasingly dependent on the availability of high-quality information from manually curated databases. Biocurators undertake the task of extracting knowledge claims from ... -
Deammonifisering av Rejekt Forbehandlet med Termisk Hydrolyse
(Master thesis, 2019)Cambi sin termiske hydrolyse prosess(THP) er en kjent og effektiv forbehandlingsprosess for slam før den stabiliseres i en råtnetank. Vannstrømmen som resulterer etter at det fordøyde slammet er avvannet, er rik på ammonium ... -
Death signals during plant cell death. Macroscopic study of cell death induced by low pH and eATP.
(Master thesis, 2023)For tiden er forskning på celledød et utviklende og svært interessant tema. Celledød som dødsprosessen i mikroskala er en viktig kontrollmekanisme i alle levende organismer. Spesielt programmert cellulært "selvmord", som ... -
Deciphering biodiversity: On the taxonomy of Northern European Darwin wasps (Hymenoptera: Ichneumonidae)
(Doctoral theses at NTNU;2022:12, Doctoral thesis, 2022)Summary of thesis: Ichneumonid or Darwin wasps is one of, possibly the largest hymenopteran family on earth and constitute a large part of what we commonly refer to as biodiversity. Despite their often large and colorful ... -
Deciphering the composition and transformation of dissolved organic matter in recirculating aquaculture systems by high-resolution mass spectrometry
(Doctoral theses at NTNU;2022:237, Doctoral thesis, 2022)The continuous increase in the human population is prompting the need for aquaculture systems able to sustain the global demand for fish without affecting the environment. Recirculating aquaculture systems (RAS) are a new ... -
Deciphering the Composition of Fulvic Acids from Recirculating Aquaculture Systems by Quadrupole Time-of-Flight Mass Spectrometry
(Peer reviewed; Journal article, 2022)The constant reuse of waters in recirculating aquaculture systems (RAS) together with the continuous addition of organic matter from fish degradation components, faeces and non-consumed feed promote the accumulation of ... -
Deciphering the Electronic Transitions of Thiophene-Based Donor-Acceptor-Donor Pentameric Ligands Utilized for Multimodal Fluorescence Microscopy of Protein Aggregates.
