      Several studies concerning the turbulent pipe flow of generalized Newtonian (GN) fluids may be found in the literature, but not for channel flow, although that has been extensively studied for other types of non-Newtonian ...
    • Turbulent flows of generalized Newtonian fluids: mechanics and structural coherence 

      Arosemena, Arturo A. (Doctoral theses at NTNU;2022:276, Doctoral thesis, 2022)
      Most flows are turbulent in nature, yet fluids exhibit a plethora of inherent responses to applied stress. Fluids that respond in a linear manner, such as water and air, are labelled as Newtonian, whereas the majority of ...
    • Twilight foraging enables European shags to survive the winter across their latitudinal range 

      Moe, Børge; Daunt, Francis; Bråthen, Vegard Sandøy; Barrett, Robert; Ballesteros, Manuel; Bjørnstad, Oskar; Bogdanova, Maria I.; Dehnhard, Nina; Erikstad, Kjell E.; Follestad, Arne; Gíslason, Sindri; Hallgrimsson, Gunnar Thor; Lorentsen, Svein-Håkon; Newell, Mark; Petersen, Aevar; Phillips, Richard A.; Ragnarsdóttir, Sunna Björk; Reiertsen, Tone Kristin; Åström, Jens; Wanless, Sarah; Anker-Nilssen, Tycho (Peer reviewed; Journal article, 2021)
      Species breeding at high latitudes face a significant challenge of surviving the winter. Such conditions are particularly severe for diurnal marine endotherms such as seabirds. A critical question is therefore what behavioural ...
    • Twinnability of Al–Mg alloys: A first-principles interpretation 

      Zhao, Dongdong; Løvvik, Ole Martin; Marthinsen, Knut; Li, Yanjun (Journal article; Peer reviewed, 2017)
      Al–Mg alloys are considered to have potentials to form twins during deformation because Mg can reduce the intrinsic stacking fault energy γISFE of Al. Nevertheless, twinning has rarely been found in Al–Mg alloys even ...
    • Twinned-domain-induced magnonic modes in epitaxial LSMO/STO films 

      Wahlström, Erik; Macia, Ferran; Boschker, Jos Emiel; Monsen, Åsmund Fløystad; Nordblad, Per; Mathieu, Roland; Kent, Andrew D.; Tybell, Thomas (Journal article; Peer reviewed, 2017)
      The use of periodic magnetic structures to control the magneto-dynamic properties of materials— magnonics—is a rapidly developing field. In the last decade, a number of studies have shown that metallic films can be patterned ...
    • Two Dimensional Fiber Bundle Bridge Model 

      Nygård, Håkon Tormodsen (Master thesis, 2016)
      The two dimensional fiber bundle bridge model is introduced, derived and studied for an uniform threshold distribution. The model is independent of history and has an adjustable effective range of interaction, which is ...
    • "Two hits - one stone" increased efficacy of cisplatin-based therapies by targeting PCNA's role in both DNA repair and cellular signaling
