In northern Norway, late/post-Caledonian extension initiated along inverted, brittle-ductile thrusts, e.g. Sørøya-Ingøya shear zone, which truncated existing, margin-oblique, late Neoproterozoic, Timanian faults and margin-parallel, latest Mesoproterozoic-mid Neoproterozoic faults related to the opening of the Asgard Sea and Iapetus Ocean. Inverted thrusts were active through the Devonian and early ...

We establish 2-jet determinacy for the symmetry algebra of the underlying structure of any (complex or real) parabolic geometry. At non-flat points, we prove that the symmetry algebra is in fact 1-jet determined. Moreover, we prove 1-jet determinacy at any point for a variety of non-flat parabolic geometries—in particular torsion-free, parabolic contact, and several other classes.

The present multiproxy investigation of marine sediment cores aims at: 1) Identifying dispersion of petroleum exploration related drill cutting releases within the Goliat Field, Barents Sea in 2006/07 and 2) Assessing past and present influence of drill cuttings on the marine environment. The cores were recovered 5, 30, 60, 125 and 250 m from the drill site in the eastward downstream direction.<p> ...

The efficiency of bacteria in acquiring resistance for their survival ensures a never-ending war against resistance. The only tactic to curtail the resistance crisis is to keep pace with it, e.g. by continuous development of new antibiotics with activity against resistant bacteria or revival of existing agents by inhibiting the mechanisms of resistance. β-lactams are the largest and most widely used ...

Denne masteroppgaven søker å forstå hvorfor noen valgte å reise til kriserammede Hellas under flyktningkrisen i 2015-2016 for å bistå som frivillig hjelpearbeider. Å forstå dette frivillige engasjementet kan være viktig og av betydning for andre krisesituasjoner. I tillegg er det viktig å se hvordan den type arbeid kan påvirke de frivillige etter endt tjeneste, derfor fokuserer denne oppgaven også ...

Rare CO2 flux measurements from Arctic pack ice show that two types of ice contribute to the release of CO2 from the ice to the atmosphere during winter and spring: young, thin ice with a thin layer of snow and older (several weeks), thicker ice with thick snow cover. Young, thin sea ice is characterized by high salinity and high porosity, and snow-covered thick ice remains relatively warm ( >  −7.5 °C) ...

Forskningsstudien er en case-studie. Casen er to pedagoger fra Nordnorsk Vitensenter og deres arbeidsform med matematikkundervisning. Studien undersøker hvordan vitensenterpedagogenes arbeidsform kan relateres til Lesson Study og til matematisk kreativt arbeid gjennom Sriramans definisjon. Studien indikerer at arbeidsformen til vitensenterpedagogene kan relateres til Lesson Study gjennom et påstått ...

We present the first observations, to our knowledge, of a new class of high‐latitude mesosphere‐stratosphere‐troposphere radar echoes from the E region as observed with the Arctic Lidar Observatory for Middle Atmosphere Research wind radar during the period 2004–2008. These echoes occur primarily during the summer months and in the altitude range from 93 to 114 km, with a pronounced peak of maximum ...

Changes in Arctic sea ice have raised questions about changes in sea ice drift patterns. Reduced sea ice coverage may open up the Arctic to further exploration of maritime activities, particularly during the summer months. Given such changes, it is important to investigate differences between available sea ice drift products. Products based on synthetic aperture radar (SAR), radar scatterometer, and ...

High-resolution swath-bathymetry data integrated with sub-bottom profiles and single-channel seismics reveal an 18 km long, up to 1000 m wide and 10-15 m deep crack located approx. 4 km upslope from a slide scar on the continental slope off northern Norway. This crack is formed by subsidence of the sea-floor sediments to a depth of 120 m due to downslope movement of a ~80 km2 large sediment slab ...
