      Woldaregay, Ashenafi Zebene; Årsand, Eirik; Walderhaug, Ståle; Albers, David; Mamykina, Lena; Botsis, Taxiarchis; Hartvigsen, Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-26)
      <i>Background</i>: Diabetes mellitus (DM) is a metabolic disorder that causes abnormal blood glucose (BG) regulation that might result in short and long-term health complications and even death if not properly managed. Currently, there is no cure for diabetes. However, self-management of the disease, especially keeping BG in the recommended range, is central to the treatment. This includes actively ...
    • Evolution of a rock slope failure at Skredkallen, Vannøya 

      Mikkelsen, Martin (Master thesis; Mastergradsoppgave, 2019-11-15)
      Rock slope failures are known major contributors to landscape evolution in alpine Norway, and also pose a threat to people and infrastructure in the present day. By examining the history of rock slope failures at active rockslide sites an understanding of recurrence intervals and triggering mechanisms can be achieved. The focus of this study is to form a complete picture of the evolution of an area ...
    • Accumulated marine pollution and fishery dynamics 

      Bergland, Harald; Pedersen, Pål Andreas; Wyller, John Andreas (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-05)
      We analyze the possible impacts of pollution on a fishery by means of a dynamical systems theory approach. The proposed model presupposes that activities stimulating economic growth also cause higher emissions that remediate or accumulate in the oceans. The density of pollution is assumed to affect the fishery negatively by reducing biological growth potential and decreasing marginal willingness to ...
    • Efficiency and traffic safety with pay for performance in road transportation 

      Bergland, Harald; Pedersen, Pål Andreas (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-01)
      We propose a theoretical model in order to study the behavior of a road transport company and a driver. The driver is supposed to face a pay for performance contract. The expected profit for the company and the expected utility for the driver depend on the input chosen by themselves and the other actor. By analyzing the possible interaction going on between the actors in a simultaneous game and the ...
    • Researching phonological variation in child, learner and adult speech: The case of schwa in French 

      Andreassen, Helene N. (Conference object; Konferansebidrag, 2019-11-11)
      Phonological variation can be defined as describing “a situation in which a single morpheme can be realized in more than one phonetic form in a single environment” (Coetzee & Pater, 2011, p. 401). In the latter decades, research on this integral part of grammar has become increasingly important, resulting not only in a growing literature on the topic, but also in large datasets on which hypotheses ...

    • En sang til (livs)motet - en undring omkring fenomenet livsmot 

      Thorsen, Rolf (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-25)
      This essay addresses various aspects of the phenomenon of “life courage”. The approach is phenomenological and draws on a Danish tradition of life philosophy. The aim is not to find definitions, but to approach the topic cautiously to reveal new aspects of the phenomenon. The text is an outer and inner journey through experience, art, literature and poetry. This journey starts by dwelling on the ...
    • Four-component relativistic time-dependent density-functional theory using a stable noncollinear DFT ansatz applicable to both closed- and open-shell systems 

      Komorovsky, Stanislav; Cherry, Peter J.; Repisky, Michal (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-14)
      We present a formulation of relativistic linear response time-dependent density functional theory for the calculation of electronic excitation energies in the framework of the four-component Dirac-Coulomb Hamiltonian. This approach is based on the noncollinear <i>ansatz</i> originally developed by Scalmani and Frisch [J. Chem. Theory Comput. 8, 2193 (2012)] and improves upon the past treatment of ...
    • Relativistic four-component linear damped response TDDFT for electronic absorption and circular dichroism calculations 

      Konecny, Lukas; Repisky, Michal; Ruud, Kenneth; Komorovsky, Stanislav (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-21)
      We present a detailed theory, implementation, and a benchmark study of a linear damped response time-dependent density functional theory (TDDFT) based on the relativistic four-component (4c) Dirac–Kohn–Sham formalism using the restricted kinetic balance condition for the small-component basis and a noncollinear exchange–correlation kernel. The damped response equations are solved by means of a ...
    • Epifaunal communities across marine landscapes of the deep Chukchi Borderland (Pacific Arctic) 

      Zhulay, Irina; Iken, Katrin; Renaud, Paul Eric; Bluhm, Bodil (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-27)
      Epifaunal communities from the poorly studied Arctic deep sea of the Chukchi Borderland region were investigated to: (1) determine differences in community structure among ridges, plateau with pockmarks, and much deeper basins as three main habitat types, (2) analyse the environmental factors that might shape these communities, and (3) investigate biogeographic affinities dominating the epifaunal ...
    • Identification of evolutionary and kinetic drivers of NAD-dependent signaling 

      Bockwoldt, Mathias; Houry, Dorothee; Niere, Marc; Gossmann, Toni I.; Reinartz, Ines; Schug, Alexander; Ziegler, Mathias; Heiland, Ines (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-24)
      Nicotinamide adenine dinucleotide (NAD) is best known as an essential cofactor of biochemical reactions. In addition, it is involved in the regulation of virtually all major cellular events. These NAD-dependent regulatory functions are mediated by enzymes (e.g., sirtuins, poly–adenosine -diphosphate [ADP] ribose polymerases, ADP-ribosyl cyclases) that cleave the molecule to liberate nicotinamide ...

      Borge, Baard Herman (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-08)
      Using transition theory from political science, this paper analyses how the lives of children of Norwegians punished for collaboration with the German occupant were adversely influenced by transitional justice after the return to democracy in 1945. The paper highlights how the complexity and hectic character of such regime changes are associated with a high risk for unintended social outcomes, a ...
    • Use of traditional and complementary medicine among Norwegian cancer patients in the seventh survey of the Tromsø study 

      Kristoffersen, Agnete Egilsdatter; Stub, Trine; Broderstad, Ann Ragnhild; Hansen, Anne Helen (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-29)
      <i>Background</i>: Traditional and complementary medicine (T&CM) is commonly used by cancer patients in Northern Norway, in particular spiritual forms like traditional healing. T&CM is mainly used complementary to conventional cancer treatment and is rarely discussed with conventional health care providers, increasing the risk of negative interaction with conventional cancer care. The aim of this ...
