    • Wake formation behind Langmuir probes in ionospheric plasmas 

      Jao, Chun-Sung; Marholm, Sigvald; Spicher, Andres; Miloch, Wojciech Jacek (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-20)
      This paper presents a simulation study of the wake formation behind a Langmuir probe thinner than the Debye Length in the space environments such as the ionosphere’s F region. We find that the wakes formed in plasma density and electric potential behind the positively biased probe can extend up to 15 Debye lengths in the subsonic plasma flow. Higher electric bias and flow velocity can further enhance ...
    • Warm temperatures during cold season can negatively affect adult survival in an alpine bird 

      Chiffard, Jules; Delestrade, Anne; Yoccoz, Nigel Gilles; Loison, Anne; Besnard, Aurelien (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-25)
      Climate seasonality is a predominant constraint on the lifecycles of species in alpine and polar biomes. Assessing the response of these species to climate change thus requires taking into account seasonal constraints on populations. However, interactions between seasonality, weather fluctuations, and population parameters remain poorly explored as they require long‐term studies with high sampling ...

      Wang, X.; Chapman, Sandra; Dendy, R.O.; Hnat, B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-20)
      Context. The high Reynolds number solar wind flow provides a natural laboratory for the study of turbulence in situ. Parker Solar Probe samples the solar wind between 0.17 AU and 1 AU, providing an opportunity to study how turbulence evolves in the expanding solar wind.<p> <p>Aims. We aim to obtain estimates of the scaling exponents and scale breaks of the power spectra of magnetohydrodynamic ...
    • Wavelet-based analogous phase scintillation index for high latitudes 

      Ahmed, Abu Baker E.; Tiwari, Rajesh N.; Strangeways, Hal J.; Dlay, Satnam Singh; Johnsen, Magnar Gullikstad (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-07-14)
      The Global Positioning System (GPS) performance at high latitudes can be severely affected by the ionospheric scintillation due to the presence of small-scale time-varying electron density irregularities. In this paper, an improved analogous phase scintillation index derived using the wavelet-transform-based filtering technique is presented to represent the effects of scintillation regionally at ...

    • Weakly nonlinear ion sound waves in gravitational systems 

      Guio, Patrick; Pécseli, Hans L (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-27)
      Ion sound waves are studied in a plasma subject to gravitational field giving rise to vertically inhomogeneous steady-state plasma conditions. Such systems are interesting by exhibiting a wave growth that is a result of energy flux conservation for pulses propagating in an inhomogeneous system. The increase of the amplitude of a pulse as it propagates along the density gradient in the direction of ...

      Fjellström, Sanna; Hansen, Elisabeth; Hölltä, Jessica; Zingmark, Magnus; Nordstrom, Anna Hava; Marie Lund, Ohlsson (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-10)
      Background - Individuals with intellectual disability (ID) are less physically active, have a higher body mass index (BMI) and are at greater risk for cardiovascular diseases (CVDs) than people without ID. The purpose of the study was to explore the effectiveness of a web-based training programme, consisting of 150 min of activity per week, on the health of people with ID.<p> <p>Method - Participants ...
    • Webometrics : ranking Web of Repositories. To count and not to count 

      Longva, Leif (Journal article; Tidsskriftartikkel, 2012)
      Når Cybermetrics Lab beregner sin “Ranking Web of Repositories”, teller de lenker til vitenarkivenes innhold, som en av fire faktorer de bygger sin ranking på. Men de teller kun lenker som er bygd opp slik som Cybermetrics Lab selv mener at lenker bør være bygd opp. Andre lenker blir kort og godt ignorert. Og dette er ikke begrunnet med tekniske begrensninger, men utelukkende med Cybermetrics Labs ...
    • Welfare Technologies in Care Work 

      Kamp, Annette; Obstfelder, Aud; Andersson, Katarina (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-03)
      Welfare technologies have within the last few years become a new mantra for reforming the Nordic public health and social care, and are increasingly making their impact on working life of care professionals. Welfare technologies – a term exclusively used in a Nordic context – is a broad and loosely defined concept that covers a wide array of technologies such as tele-care solutions, automatic ...
    • What Are Demanding Operations In Subsea Work? 

      Håvold, Jon Ivar; Vederhus, Lillian; Nistad, Steinar (Journal article; Tidsskriftartikkel; Peer reviewed, 2018)
      In recent years, offshore operations have changed from a focus on anchor handling and rigging to more subsea installation and IMR (inspection, maintenance, repair). Situations where large and heavy modules are placed on the seabed by increasingly specialized and bigger boats creates the potential for major accidents. To uncover the safety challenges of this new development, 14 semi-structured in-depth ...
    • What are diabetes patients versus health care personnel discussing on social media? 

      Årsand, Eirik; Bradway, Meghan; Gabarron, Elia (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-13)
      <p><i>Background - </i>Use of social media is increasing rapidly, also in health care and diabetes. However, patients, health care personnel, and patient organizations discuss diabetes on social media very differently. This has led to a lack of common ground when these stakeholders communicate about diabetes and a gap in understanding one another’s point of view. Social media have a potential for ...
    • What Counts as Quality Feedback? Disciplinary Differences in Students’ and Teachers’ Perceptions of Feedback 

      Esterhazy, Rachelle; Fossland, Trine; Stalheim, Odd Rune (Chapter; Bokkapittel, 2020-07-02)
      As the literature has shown, students and teachers in different higher education settings often perceive the quality of feedback in varying ways. Recognising that the discipline is important for the way students and teachers perceive teaching and learning in higher education, we assume that the perceived quality of feedback is related to the specific teaching-learning environment in which it is ...

    • What makes good science? Information literacy seminars as a means to stimulate reflection among PhD students 

      Andreassen, Helene N.; Østvand, Lene (Conference object; Konferansebidrag, 2016-06-02)
      In addition to the demanding task of writing a thesis, PhD students face the challenge of balancing the roles as “good scientists” and “good academics”, which in some cases might conflict (Carter, 2015). They are expected to carry out a laborious research project where they are responsible for keeping in line with the norms and values of research ethics, all while building the foundation for their ...
    • What may we hope for? Education in times of climate change 

      Straume, Ingerid (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-10)
      In “The Crisis in Education,” published in 1954, Hannah Arendt suggests that adults who refuse to take responsibility for the world should not be allowed to educate children or to have children of their own. Her text describes the “general crisis,” which, according to Arendt, “has overtaken the modern world everywhere and in almost every sphere of life,” including education (Arendt, 2006, p. 170). ...
    • What should be the baseline when calculating excess mortality? New approaches suggest that we have underestimated the impact of the COVID-19 pandemic and previous winter peaks 

      Shkolnikov, Vladimir M.; Klimkin, Ilya; McKee, Martin; Jdanov, Dmitri A.; Alustiza-Galarza, Ainhoa; Németh, László; Timonin, Sergey A.; Nepomuceno, Marília R.; Andreev, Evgeny M.; Leon, David A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-18)
      Excess mortality has been used to measure the impact of COVID-19 over time and across countries. But what baseline should be chosen? We propose two novel approaches: an alternative retrospective baseline derived from the lowest weekly death rates achieved in previous years and a within-year baseline based on the average of the 13 lowest weekly death rates within the same year. These baselines express ...
    • What should have happened if Hardy had discovered this? 

      Persson, Lars Erik; Samko, N (Journal article; Tidsskriftartikkel; Peer reviewed, 2012-02-15)
      First we present and discuss an important proof of Hardy’s inequality via Jensen’s inequality which Hardy and his collaborators did not discover during the 10 years of research until Hardy finally proved his famous inequality in 1925. If Hardy had discovered this proof, it obviously would have changed this prehistory, and in this article the authors argue that this discovery would probably also ...
    • What's with the boys? Lower birth weight in boys from HPA-1a alloimmunized pregnancies – New insights from a large prospective screening study in Poland 

      Coucheron, Tina; Uhrynowska, Malgorzata; Guz, Katarzyna; Orzińska, Agnieszka; Debska, Marzena; Gierszon, Agnieszka; Ahlen, Maria Therese; Bertelsen, eirin listau; Berge, gerd; Husebekk, Anne; Brojer, Ewa; Tiller, Heidi (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-07)
      Fetomaternal incompatibility in human platelet antigens (HPAs) can cause maternal alloimmunization, which in turn may lead to thrombocytopenia with or without intracranial hemorrhage (ICH) in the fetus or newborn. Retrospective studies suggest that boys from alloimmunized mothers may have higher risk of ICH and lower birth weight than girls. The objective of this study was to assess how maternal ...
