• Triggers and risk factors of first and recurrent venous thromboembolism 

    Bjøri, Esben (Doctoral thesis; Doktorgradsavhandling, 2020-01-29)
    Venous thromboembolism (VTE), encompassing both deep vein thrombosis and pulmonary embolism, is a major public health concern due to substantial morbidity and mortality. Around half of all VTE cases are hospital-related. Importantly, VTE also has life-long implications, as a large proportion of VTE-patients suffer either a recurrent event or chronic complications. The first aim of the thesis was to ...
  • Facilitation mediates species presence beyond their environmental optimum 

    O'Brien, Michael J; de Menezes, Luis Fernando Tavares; Bråthen, Kari Anne; Losapio, Gianalberto; Pugnaire, Francisco I. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-01)
    Species distributions are driven by abiotic conditions that filter species with specific traits and physiological tolerances and match them with their suitable environment. Plant–plant interactions can constrict (through competition) or loosen (through facilitation) the strength of these environmental filters, which in turn inhibit or enhance establishment and recruitment of plant species at a finer ...
  • Behavior and thermal environment of Chinook salmon Oncorhynchus tshawytscha in the North Pacific Ocean, elucidated from pop-up satellite archival tags 

    Courtney, Michael B.; Evans, Mark D.; Strøm, John Fredrik; Rikardsen, Audun H.; Seitz, Andrew C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-22)
    Chinook salmon are widely distributed in offshore waters of the North Pacific Ocean, and of great economical and subsistence importance; however, little is known about their oceanic ecology. To address this, we tagged 43 Chinook salmon <i>Oncorhynchus tshawytscha</i> (57–100 cm) with pop-up satellite archival tags (PSATs) in the eastern (October– December) and central Bering Sea (August) to provide ...
  • Variation in use of open and laparoscopic distal pancreatectomy and associated outcome metrics in a universal health care system 

    Søreide, Kjetil; Nymo, Linn Såve; Kleive, Dyre; Olsen, Frank; Lassen, Kristoffer (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-01)
    <i>Background</i> - Universal health care (UHC) should ensure equal access to and use of surgery, but few studies have explored variation in UHC systems. The objective was to describe practice of distal pancreatectomy in Norway covered exclusively by an UHC.<p><p> <i>Methods</i> - Data on all patients undergoing distal pancreatectomy from the Norwegian Patient Register over a 5-year period. ...
  • Energetic electron precipitation occurrence rates determined using the Syowa East SuperDARN Radar 

    Bland, Emma; Partamies, Noora; Heino, Erkka; Yukimatu, Akira Sessai; Miyaoka, Hiroshi (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-04)
    We demonstrate that the Super Dual Auroral Radar Network (SuperDARN) radar at Syowa station, Antarctica, can be used to detect high frequency radio wave attenuation in the <i>D</i> region ionosphere during energetic electron precipitation (EEP) events. EEP‐related attenuation is identified in the radar data as a sudden reduction in the backscatter power and background noise parameters. We focus ...
