      Myrstad, Anne; Kleemann, Carola (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-08)
      The authors explore how multiple viewpoints can challenge our habitualised way of viewing and expand the area of thinking about children’s outdoor learning. They draw on micro-fieldwork in a Sámi kindergarten in Arctic Norway. There, learning through participation and practical experiences is a traditional strategy in child rearing. This method of learning is currently being transformed in Sámi ...
    • Visualizing and interpreting surface displacement patterns on unstable slopes using multi-geometry satellite SAR interferometry (2D InSAR) 

      Eriksen, Harald Øverli; Lauknes, Tom Rune; Larsen, Yngvar; Corner, Geoffrey D.; Bergh, Steffen G; Dehls, John; Kierulf, Halfdan Pascal (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-05)
      It is well known that satellite radar interferometry (InSAR) is capable of measuring surface displacement with a typical accuracy on the order of millimeters to centimeters. However, when the true deformation vector differs from the satellite line-of-sight (LOS), the sensitivity decreases and interpretation of InSAR deformationmeasurements becomes challenging. By combining displacement data ...
    • Visualizing tephra deposits and sedimentary processes in the marine environment: The potential of X-ray microtomography 

      Griggs, Adam J.; Davies, Siwan M.; Abbott, Peter M.; Coleman, Mark; Palmer, Adrian P.; Rasmussen, Tine Lander; Johnston, Richard (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-30)
      Localized tephra deposition in marine sequences is the product of many complex primary and secondary depositional processes. These can significantl y influence the potential applicability of tephra depos- its as isochronous marker horizons and current techniques, used in isolation, may be insufficient to fully unravel these processes. Here we demonstrate the innovative application of X-ray ...

    • The Vitae of Nil Sorskii’s “Sobornik”: Translation or Periphrasis? 

      Lönngren, Tamara (Journal article; Tidsskriftartikkel, 2003)
      This paper attempts to show that Nil Sorskii, the author of the well-known three-volume “Sobornik”, in compiling this collection of ancient Greek vitae used Greek texts as well as Slavonic translations. He compared the Slavonic texts with the Greek originals and corrected their difficult archaic language, thus turning it into the understandable simple Russian language of his own time.
