Lakes and wetlands, common ecosystems of the high northern latitudes, exchange large amounts of the climate-forcing gases methane (CH4) and carbon dioxide (CO2) with the atmosphere. The magnitudes of these fluxes and the processes driving them are still uncertain, particularly for subarctic and Arctic lakes where direct measurements of CH4 and CO2 emissions are often of low temporal resolution and ...

Sammendrag Mål: Målet med denne prospektive studien var å undersøke om psykologisk stress og sykdomsforståelse kan påvirke smertetilstanden og funksjonsbegrensning hos pasienter med leddgikt - revmatoid artritt (RA). Metode: Tre hundre og fem pasienter med RA behandlet ved UNN (Universitetssykehuset i Nord-Norge) ble kontaktet via post og invitert til å delta. Data ble innsamlet ved å bruke ...

Background: <br>A previous randomised controlled trial (RCT) of patients with chronic low back pain (LBP) and vertebral bone marrow (Modic) changes (MCs) on magnetic resonance imaging (MRI), reported that a 3-month, high-dose course of antibiotics had a better effect than placebo at 12 months’ follow-up. The present study examines the effects of antibiotic treatment in chronic LBP patients with ...

Retrievals of sea ice drift from synthetic aperture radar (SAR) images at high spatial resolution are valuable for understanding kinematic behavior and deformation processes of the ice at different spatial scales. Ice deformation causes temporal changes in patterns observed in sequences of SAR images; which makes it difficult to retrieve ice displacement with algorithms based on correlation and ...

I denne studien utforsket vi et utvalg «Min undervisningsfilosofi»-tekster for å søke svar på hva vitenskapelig ansatte trekker frem når de reflekterer over egen undervisning. Arbeidet tok utgangspunkt i idéen om at for å utvikle og øke kvaliteten på sin undervisning er det nødvendig at vitenskapelig ansatte for det første tilegner seg teoretisk kunnskap om undervisning og læring (Handal, 2006), ...

This paper shows initial results from estimating Doppler radial surface velocities (RVLs) over Arctic sea ice using the Sentinel-1A (S1A) satellite. Our study presents the first quantitative comparison between ice drift derived from the Doppler shifts and drift derived using time-series methods over comparable time scales. We compare the Doppler-derived ice velocities with global positioning system ...

Background: <br>The zoonotic Orf virus (ORFV; genus Parapoxvirus, Poxviridae family) occurs worldwide and is transmit‑ted between sheep and goats, wildlife and man. Archived tissue samples from 16 Alaskan wildlife cases, representing mountain goat (Oreamnos americanus, n= 8), Dall’s sheep (Ovis dalli dalli, n= 3), muskox (Ovibos moschatus, n= 3), Sitka black‑tailed deer (Odocoileus hemionus sitkensis, ...

Introduction:<br> Women with bulimia nervosa and binge eating disorder often suffer for many years before they seek professional help. Evidence-based treatments like cognitive–behavioural therapy (CBT) might be poorly accessible, and about 50% of those who receive CBT respond to it. Such outcome may reflect the heterogeneous nature of eating disorders, and addressing this heterogeneity calls ...

The SW Barents Sea margin experienced a pulse of extensional deformation in the Middle–Late Devonian through the Carboniferous, after the Caledonian Orogeny terminated. These events marked the initial stages of formation of major offshore basins such as the Hammerfest and Nordkapp basins. We mapped and analyzed three major fault complexes, (i) the Måsøy Fault Complex, (ii) the Rolvsøya fault, and ...

The physiological effects of transcranial direct current stimulation (tDCS) in the living human brain were verified experimentally in the early 2000's. A series of studies from Göttingen, Germany, shows that consistently, anodal stimulation lead to increased cortical excitability, while cathodal stimulation leads to increased cortical inhibition. Since then, the effect of tDCS has been further ...
