We present here observations of the polarisation of four auroral lines in the auroral oval and in the polar cusp using a new ground polarimeter called <i>Petit Cru</i>. Our results confirm the already known polarisation of the red line, and show for the first time that the three other lines observed here (namely 557.7 nm, 391.4 nm and 427.8 nm) are polarised as well up to a few percent. We show that ...

High levels of organochlorines (OCs) have been measured in arctic char (<i>Salvelinus alpinus</i>) from Lake Ellasjøen on Bjørnøya, Norway (74.30°N, 19.0°E). In a nearby lake, Laksvatn, the OC-levels in arctic char were low. A previous study has shown that char from Ellasjøen had significantly higher levels of DNA double strand breaks (DSBs) than char from Lake Laksvatn. Even though there is increasing ...

Colonoscopy is considered the gold standard for detection of colorectal cancer and its precursors. Existing examination methods are, however, hampered by high overall miss-rate, and many abnormalities are left undetected. Computer-Aided Diagnosis systems based on advanced machine learning algorithms are touted as a game-changer that can identify regions in the colon overlooked by the physicians ...

Whereas left atrial (LA) enlargement is an independent predictor for adverse cardiovascular events and all-cause mortality, this is regarded a physiological adaption of exercise. Paradoxically, LA size in athletes may overlap the enlargement observed in patients with cardiac pathology. Current knowledge is mainly derived from studies of athletes, and little is known about cardiac adaptations to ...

Artikkelens utgangspunkt er en problematisering av kunnskapsgrunnlaget for metodeundervisningen i barnehagelærerutdanningen (BLU). Tidligere forskning avdekker manglende sammenheng mellom utdanningskvalifisering og yrkespraksis. Metodologisk kunnskap er sentralt for å kunne gjøre kvalifiserte valg og for å kunne utvikle og endre personlige og profesjonelle praksiser. Vi argumenterer for ...

Andøya on the NW coast of Norway is a key site for understanding the Last Glacial Maximum (LGM) in northern Europe. Controversy has arisen concerning the local conditions, especially about the timing and extent of local glacial cover, maximum July temperatures and whether pine and/or spruce could have grown there. We reviewed all existing data and add newly analysed ancient sedimentary DNA ...

A 24,000-year record of plant community dynamics, based on pollen and ancient DNA from the sediments (<i>seda</i>DNA) of Lake Bolshoye Shchuchye in the Polar Ural Mountains, provides detailed information on the flora of the Last Glacial Maximum (LGM) and also changes in plant community composition and dominance. It greatly improves on incomplete records from short and fragmented stratigraphic sequences ...

<i>Background</i> - The current study was aimed at investigating the feasibility of hippocampus‐avoidance whole‐brain radiation therapy with a simultaneous integrated boost (HA‐WBRT+SIB) for metastases and at assessing tumor control in comparison with conventional whole‐brain radiation therapy (WBRT) in patients with multiple brain metastases.<p> <p><i>Methods</i> - Between August 2012 and December ...

Seismic surveying of the coastal areas in the Arctic is best facilitated during wintertime when the sea ice is land‐fast. This eases the logistics of the operation and assures that there is no damage made to the vulnerable tundra. Seismic experiments on floating ice on shallow water performed in a fjord in Svalbard in the Norwegian Arctic show prominent Scholte waves. The dispersion relation of ...

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 ...
