Tree thinking cannot taken for granted: challenges for teaching phylogenetics
(Journal article; Peer reviewed, 2008)Tree thinking is an integral part of modern evolutionary biology, and a necessary precondition for phylogenetics and comparative analyses. Tree thinking has during the 20th century largely replaced group thinking, de ... -
Trend of Fire Outbreaks in Ghana and Ways to Prevent These Incidents
(Peer reviewed; Journal article, 2016)Background In Ghana, fire incidents have become a regular occurrence, with thousands of lives and millions of dollars lost every year. Hardly a day passes without news of a fire outbreak in some part of Ghana, causing ... -
Trender og sammenhenger for vannkvalitet i Jonsvatnets nedbørfelt
(Master thesis, 2019)Gjennom denne masteroppgaven ble driftsdata fra Vikelvdalen vannbehandlingsanlegg undersøkt for å bekrefte antagelser om forhold i Jonsvatnet, samt undersøke om det finnes forhold som indikerer trusler mot vanntryggheten. ... -
Trends and Challenges for Electrowinning of Aluminium and Magnesium from Molten Salt Electrolytes
(Peer reviewed; Journal article, 2020)Modern aluminium producing cells are operating at ~955–965 °C. The current efficiency with respect to aluminium can be as high as 96% and the corresponding energy consumption may be ~13 kWh/kg Al and higher in cells running ... -
Trends in food emulsion technology: Pickering, nano-, and double emulsions
(Peer reviewed; Journal article, 2023)Natural and industrial foods are often structured materials that impart texture, flavor, visual appearance, and nutritional value to the product, such as liquid–liquid emulsions stabilized by complex interfaces. This article ... -
Tribological Performance of Polymers and Lubricants Used in Offshore Compensating Hydraulic Cylinders
(Master thesis, 2014)The direct-acting (N-line) riser tensioning system is a commonly selected option for riser tensioning on offshore deepwater drilling vessels. As the system operates in the splash zone, it is exposed to a corrosive environment ... -
Tribology Mechanisms in Low-Friction Hardbanding Coatings.
(Master thesis, 2013)As the shallow and easily accessible oil and gas reservoirs are becoming depleted, the oil and gas industry has turned its attention towards the deeper and more remote reservoirs. The increased drilling depth, more complex ... -
Triple-phase ceramic 2D nanocomposite with enhanced thermoelectric properties
(Journal article; Peer reviewed, 2019)A thermoelectric triple-phase p-type Ca3Co4O9-NaxCoO2-Bi2Ca2Co2O9 (CCO–NCO–BCCO) 2D nanocomposite was obtained from pressureless sintering in air. The anisotropic thermoelectric properties of the nanocomposite exhibit a ... -
Triplet Cooper pairs induced in diffusive s-wave superconductors interfaced with strongly spin-polarized magnetic insulators or half-metallic ferromagnets
(Journal article; Peer reviewed, 2017)Interfacing superconductors with strongly spin-polarized magnetic materials opens the possibility to discover new spintronic devices in which spin-triplet Cooper pairs play a key role. Motivated by the recent derivation ... -
Triplet proximity effect and odd-frequency pairing in graphene
(Journal article; Peer reviewed, 2010)We study the interplay between proximity-induced superconductivity and ferromagnetism in graphene by self-consistently solving the Bogoliubov de Gennes equations on the honeycomb lattice. We find that a strong triplet ... -
Triplet Proximity Effect in Heterostructures with Spin-Orbit Coupling and Precessing Magnetic Fields
(Master thesis, 2019)Vi vil bruke den kvasiklassiske teorien om superledere i det diffuse grensesjiktet for å gjennomføre to forskjellige forskningsprosjekt. Det første prosjektet ser på et sidestilt Josephson-kobling med iboende, Rashba-type ... -
Triplet supercurrent due to spin-active zones in a Josephson junction
(Journal article; Peer reviewed, 2010)Motivated by a recent experiment evidencing triplet superconductivity in a ferromagnetic Josephson junction with a Cu2MnAl-Heusler barrier, we construct a theoretical model accounting for this observation. The key ingredients ... -
Triploid Atlantic salmon in aquaculture - Consequences for fish health and welfare under farming conditions
(VKM Report;2023:22, Research report, 2023) -
Triploid Atlantic salmon × brown trout hybrids have similar seawater growth and welfare issues as triploid Atlantic salmon, but both were heavier at harvest than their diploid counterparts
(Peer reviewed; Journal article, 2022)Interspecific hybridisation may improve the farm performance of sterile triploid salmonids via heterosis (i.e. hybrid vigour). We assessed growth over the final 293 days in seawater, and harvest quality, in diploid and ... -
Trophic control of the Daphnia longispina/galeata complex in lakes containing the invasive European whitefish (Coregonus lavaretus)
(Master thesis, 2023)Miljøtilstanden i ferskvannsøkosystemer endrer seg raskt i en negativ retning. Hovedårsaken er menneskelig aktivitet, og spesielt bekymringsverdig er den pågående nedgangen i biodiversitet. Ferskvannsarter dør ut i økende ... -
Trophy Hunting Versus Ecotourism as a Conservation Model? Assessing the Impacts on Ungulate Behaviour and Demographics in the Ruaha-Rungwa Ecosystem, Central Tanzania
(Journal article, 2018)Trophy hunting may influence wildlife populations in many ways, but these effects have received little consideration in many of Africa’s protected areas. We assessed the effects of trophy hunting on group size, behaviour, ... -
TRY plant trait database – enhanced coverage and open access
(Journal article; Peer reviewed, 2019)Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem ... -
Trygg mat med HACCP-basert internkontroll
(Bachelor thesis, 2020)1.0 Sammendrag Arbeidet med denne bacheloroppgaven har vært svært spennende. I starten av semesteret hadde jeg begrenset kunnskap om både internkontroll og HACCP, men gjennom disse månedene med undersøking og skriving, har ... -
