    • Vannforsyning og barnedødelighet i Tromsø omkring 1920 

      Thorvaldsen, Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-22)
      I 1919 bygde Tromsø kommune en demning i Slettaelva på den fjellrike Kvaløya vest for byen som de neste par årene ble koblet via et undersjøisk rør til byens vannforsyningssystem for å øke vannmengden og bedre kvaliteten på byens drikkevann. Nyttårsaften 1921 ble kvaløyvannet trykksatt i Tromsø sentrum. For å undersøke hvilken effekt dette hadde på barnedødeligheten, ble medisinalberetningene og ...
    • Variability and decadal trends in the Isfjorden (Svalbard) ocean climate and circulation – An indicator for climate change in the European Arctic 

      Skogseth, Ragnheid; Olivier, Léa L.A.; Nilsen, Frank; Falck, Eva; Fraser, Neil J.; Tverberg, Vigdis; Ledang, Anna Birgitta; Vader, Anna; Jonassen, Marius Opsanger; Søreide, Janne; Cottier, Finlo Robert; Berge, Jørgen; Ivanov, Boris V.; Falk-Petersen, Stig (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      Isfjorden, a broad Arctic fjord in western Spitsbergen, has shown significant changes in hydrography and inflow of Atlantic Water (AW) the last decades that only recently have been observed in the Arctic Ocean north of Svalbard. Variability and trends in this fjord’s climate and circulation are therefore analysed from observational and reanalysis data during 1987 to 2017. Isfjorden experienced a ...
    • Variability in Resting-State Functional Magnetic Resonance Imaging: The Effect of Body Mass, Blood Pressure, Hematocrit, and Glycated Hemoglobin on Hemodynamic and Neuronal Parameters 

      Sjuls, Guro Stensby; Specht, Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-13)
      Introduction: Replicability has become an increasing focus within the scientific communities with the ongoing ‘‘replication crisis.’’ One area that appears to struggle with unreliable results is resting-state functional magnetic resonance imaging (rs-fMRI). Therefore, the current study aimed at improving the knowledge of endogenous factors that contribute to inter-individual variability. Methods: ...
    • Variation in adjunct islands: The case of Norwegian 

      Bondevik, Ingrid; Kush, Dave Whitney; Lohndal, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-11)
      Finite adjunct clauses are often assumed to be among the strongest islands for filler–gap dependency creation cross-linguistically, but Kush, Lohndal & Sprouse (2019) found experimental evidence suggesting that finite conditional <i>om</i>-adjunct clauses are not islands for topicalization in Norwegian. To investigate the generality of these findings, we ran three acceptability judgment experiments ...
    • Variation in serum PCSK9 (proprotein convertase subtilisin/kexin type 9), cardiovascular disease risk, and an investigation of potential unanticipated effects of PCSK9 inhibition 

      Brumpton, Ben Michael; Fritsche, Lars; Zheng, Jie; Nielsen, Jonas Bille; Mannila, Maria Nastase; Surakka, Ida; Rasheed, Humaira; Vie, Gunnhild Åberge; Graham, Sarah E.; Gabrielsen, Maiken Elvestad; Laugsand, Lars Erik; Aukrust, Pål; Vatten, Lars Johan; Damås, Jan Kristian; Ueland, Thor; Janszky, Imre; Zwart, John-Anker; van't Hooft, Ferdinand M.; Seidah, Nabil Georges; Hveem, Kristian; Willer, Cristen; Smith, George Davey; Åsvold, Bjørn Olav (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-15)
      PCSK9 (proprotein convertase subtilisin/kexin type 9) inhibitors reduce serum LDL (low-density lipoprotein) cholesterol (LDL-C) by increasing uptake in the liver. Although some long-term trials have evaluated their safety, broad investigations of outcomes over the lifetime, leveraging genetic variation in serum PCSK9, have seldomly been conducted. We investigated effects of these variants on a range ...

      Tamrakar, Stutee; Chen, Liguo; Sørensen, Bjørn Reidar (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-25)
      The standard for ergonomics of the thermal environment provides information on the calculation of optimal thermal comfort. Operative temperature (OT) is one of the essential elements of thermal comfort and is a function of air temperature, mean radiant temperature (MRT), and air velocity. This paper investigates the impact of diverse influences on MRT in an office room based on occupant position ...
    • Variations in the Circle of Willis in a large population sample using 3D TOF angiography: The Tromsø Study 

      Hindenes, Lars Bakke; Håberg, Asta; Johnsen, Liv-Hege; Mathiesen, Ellisiv B.; David, Robben; Vangberg, Torgil Riise (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-03)
      The main arteries that supply blood to the brain originate from the Circle of Willis (CoW). The CoW exhibits considerable anatomical variations which may have clinical importance, but the variability is insufficiently characterised in the general population. We assessed the anatomical variability of CoW variants in a community-dwelling sample (N = 1,864, 874 men, mean age = 65.4, range 40–87 years), ...

    • Vedde Ash constrains Younger Dryas glacier re-advance and rapid glacio-isostatic rebound on Svalbard 

      Farnsworth, Wesley Randall; Ingólfsson, Ólafur; Mannerfelt, Erik S.; Kalliokoski, Maarit H.; Gudmundsdottir, Esther Ruth; Retelle, Michael; Allaart, Lis; Brynjólfsson, Skafti; Furze, Mark; Hancock, Holt John; Kjær, Kurt H.; Pieńkowski, Anna J.; Schomacker, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-09)
      The distal deposition of tephra from explosive volcanism has the potential to geochronologically constrain sedimentary archives and landforms. With this technique, we constrain a Late Glacial glacier re-advance on Svalbard and suggest that glacioisostatic emergence rates during the Younger Dryas chronozone were at least three times greater than previous estimates. The identification of cryptotephra ...

    • Ventilation History of the Nordic Seas Deduced from Pelagic‐Benthic Radiocarbon Age Offsets 

      Telesiński, Maciej M.; Ezat, Mohamed; Muschitiello, Francesco; Bauch, Henning A.; Spielhagen, Robert F. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-24)
      Changes in ocean circulation are considered a major driver of centennial-to-millennial scale climate variability during the last deglaciation. Using four sediment records from the Nordic Seas, we studied radiocarbon ventilation ages in subsurface and bottom waters to reconstruct past variations in watermass overturning. Planktic foraminiferal ages show significant spatial variability over most of ...
    • Venuspassasjen 1769 : i et nordområdeperspektiv 

      Aspaas, Per Pippin; Stén, Johan Carl-Erik (Journal article; Tidsskriftartikkel, 2012)
      Planeten Venus går som kjent i bane rundt sola, innenfor jordkloden. En sjelden gang passerer den som en liten prikk foran solskiva. I år skjer dette natt til 6. juni 2012, skandinavisk tid. Venus passerte foran sola i 2004 også, men neste passasje må vi vente lenge på. Den finner ikke sted før i året 2117. På syttenhundretallet skjedde den mest betydningsfulle venuspassasjen i historien. Også den ...
    • Verbal instructions as selection bias that modulates visual selection 

      Damanskyy, Yevhen (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-15)
      Research has shown that in addition to top-down and bottom-up processes, biases produced by the repetition priming effect and reward play a major role in visual selection. Action control research argues that bidirectional effect-response associations underlie the repetition priming effect and that such associations are also achievable through verbal instructions. This study evaluated whether verbally ...
    • Vi har forlatt redaksjonsrådet i Publications 

      Frantsvåg, Jan Erik; Westlund, Oscar; Aaen-Stockdale, Craig (Journal article; Tidsskriftartikkel, 2023)
      Undertegnede har en stund vært medlemmer av redaksjonsrådet («Editorial Board») i MDPI-tidsskriftet Publications. I forrige uke gikk redaktøren, viseredaktøren og drøyt to tredjedeler av redaksjonsrådet av samtidig med oss, eller i nær tilknytning til at vi gikk av.
    • The Vicar , the Nobleman, and the Peasant: About a Book and its Readers 

      Hansen, Poul Henning Gustaf (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-22)
      This article centres around a volume of sermons and its three documented owners. The book first belonged to a vicar, then to a nobleman, and finally to a farmhand. The three owners all left marks on the book, and the farmhand wrote a remarkable passage on its last page, detailing his reading of the book. The three owners’ possession of the book spans over a century, 1766–1876, a period that saw ...
    • Vicariance followed by secondary gene flow in a young gazelle species complex 

      Garcia-Erill, Genís; Kjær, Michael Munkholm; Albrechtsen, Anders; Siegismund, Hans Redlef; Heller, Rasmus (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-23)
      Grant's gazelles have recently been proposed to be a species complex comprising three highly divergent mtDNA lineages (<i>Nanger granti, N. notata</i> and <i>N. petersii</i>). The three lineages have nonoverlapping distributions in East Africa, but without any obvious geographical divisions, making them an interesting model for studying the early-stage evolutionary dynamics of allopatric speciation ...
    • Video Recordings of Interactions 

      Warth, Line Lundvoll (Journal article; Tidsskriftartikkel; Peer reviewed, 2022)
      Video recordings are an important resource for capturing in-dept social interaction and collaboration in workplace studies. Video-recorded observations can be used to analyse knowledge expansion in collaborative work when practitioners use videoconferences (VCs). Interaction analysis of a problem-solving activity is carried out, pointing to sequences in the work where knowledge expand, and problems ...
