Taking a trip to the shelf: Behavioral decisions are mediated by the proximity to foraging habitats in the black-legged kittiwake
(Journal article; Peer reviewed, 2017)For marine top predators like seabirds, the oceans represent a multitude of habitats regarding oceanographic conditions and food availability. Worldwide, these marine habitats are being altered by changes in climate and ... -
Taming Electrons in Pt/C Catalysts to Boost the Mesokinetics of Hydrogen Production
(Peer reviewed; Journal article, 2022)Taming the electron transfer across metal–support interfaces appears to be an attractive yet challenging methodology to boost catalytic properties. Herein, we demonstrate a precise engineering strategy for the carbon surface ... -
Tandem Catalytic Upgrading of Biomass Fast-Pyrolysis Constituents to Fuels
(Doctoral theses at NTNU;2019:51, Doctoral thesis, 2019)The increasing human population and it’s associated economic, environment and geopolitical demands towards sustainable transport energy have advanced research onto renewable liquid fuel production and aviation fuel range ... -
Tandem hydrodeoxygenation catalyst system for hydrocarbons production from simulated bio-oil: Effect of C-C coupling catalysts
(Peer reviewed; Journal article, 2021)Research in the sustainable conversion of biomass to fuels and chemicals is a necessity for the reduction of the carbon footprint in transport energy. Herein, we demonstrate an efficient tandem catalyst to selectively ... -
Tap av areal for sjøørret (Salmo trutta) i elver og bekkar i Ålesund kommune
(Bachelor thesis, 2023)Samandrag Denne bacheloroppgåva kvantifiserer tapet av anadromt elveareal, innsjøareal og elvestrekning i 29 vassdrag i Ålesund kommune. Dagens tilstand er samanlikna med «original» tilstand, som vil seie den opphavelege ... -
Tap av gruntvannsområder i indre Nordfjord som følge av utfylling og mudring.
(Bachelor thesis, 2023)I historisk sammenheng har elvedaler innerst i fjordarmer vært viktige bosetningsområder, og dannet grunnlaget for mange av de største tettstedene i Norge i dag. Dette har ført til behov for infrastruktur og sentrumsutvikling, ... -
Tapered silicon core fibers with nano-spikes for optical coupling via spliced silica fibers
(Journal article; Peer reviewed, 2017)Abstract: Reported here is the fabrication of tapered silicon core fibers possessing a nanospike input that facilitates their seamless splicing to conventional single mode fibers. A proofof-concept 30 µm cladding diameter ... -
Tapping Gas from the Silicon Submerged Arc Furnace: An Industrial Measurement Campaign
(Journal article; Peer reviewed, 2022)Producing high-silicon alloys in submerged arc furnaces (SAF) involves the generation of an intermediate process gas, consisting of silicon monoxide (SiO) and carbon monoxide (CO). Combustion of process gas from the taphole ... -
Tapping of FeSi Furnaces
(Master thesis, 2018)Ferrosilicon is usually produced in an electric arc furnace. During the tapping of the furnace solidification of FeSi and slag in the runner and ladle are a major issue because it lowers the ferrosilicon yield and causes ... -
Target tissue toxicity of the thyroid hormone system in two species of arctic mammals carrying high loads of organohalogen contaminants
(Doctoral thesis at NTNU;2014:330, Doctoral thesis, 2014)Background: Arctic marine top predators such as the hooded seals (Cystophora cristata) and polar bears (Ursus maritimus) are exposed to and bioaccumulate high levels of lipophilic organohalogen contaminants (OHCs) through ... -
Targeted Mass Spectrometric Metabolite Profiling for Studies of Central Carbon Metabolism
(Doctoral theses at NTNU;2020:194, Doctoral thesis, 2020)Metabolism is the total set of enzymatic reactions occurring in a cell, tissue, organ, or organism to sustain life. It is an implementation of all upstream levels of regulation and environmental stimuli and hence reflecting ... -
Targeted mutagenesis of Δ5 and Δ6 fatty acyl desaturases induce dysregulation of lipid metabolism in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2020)Background With declining wild fish populations, farmed salmon has gained popularity as a source for healthy long-chain highly unsaturated fatty acids (LC-HUFA). However, the introduction of plant oil in farmed salmon ... -
Targeting Cytosolic Phospholipase A2 alpha (cPLA2α) in Hematological Cancers and Inflammation
(Doctoral theses at NTNU;2023:409, Doctoral thesis, 2023)Cytosolic phospholipase A2 alpha (cPLA2α) is an enzyme that plays a crucial role in regulating the balance between cellular growth and death by releasing the unsaturated fatty acid arachidonic acid from membrane lipids. ... -
Targeting kinetics of RGD-conjugated nanoemulsions
(Master thesis, 2015)The overall aim of this project was to study targeting kinetics of fluorescently labelled RGD-conjugated nanoemulsions (RGD-NE) to avb3-expressing human umbilical vein endothelial cells, and obtain a better understanding ... -
Tau Protein Binding Modes in Alzheimer’s Disease for Cationic Luminescent Ligands
(Journal article; Peer reviewed, 2021)The bi-thiophene-vinylene-benzothiazole (bTVBT4) ligand developed for Alzheimer’s disease (AD)-specific detection of amyloid tau has been studied by a combination of several theoretical methods and experimental spectroscopies. ... -
Taxonomy and conservation status of hawk-eagles (Genus Nisaetus) in south-east Asia
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:91, Doctoral thesis, 2006)Morphological, vocal and molecular data have been used to reevaluate the taxonomy of some Asian Nisaetus taxa. This name is used instead of Spizaetus because the latter genus is polyphyletic with clades in Asia, South ... -
TD-DFT based fine-tuning of molecular excitation energies using evolutionary algorithms
