Mesoscale dynamics in the mesosphere and lower thermosphere (MLT) region have been difficult to study from either ground- or satellite-based observations. For understanding of atmospheric coupling processes, important spatial scales at these altitudes range between tens and hundreds of kilometers in the horizontal plane. To date, this scale size is challenging observationally, so structures are ...

Taylor's hypothesis, or the frozen turbulence approximation, can be used to estimate also the specific energy dissipation rate ϵ by comparing experimental results with the Kolmogorov–Obukhov expression. The hypothesis assumes that a frequency detected by an instrument moving with a constant large velocity <i><b>V</i></b> can be related to a wavenumber by <i><b>ω=kV</i></b>. It is, however, not obvious ...

BAKGRUNN I norske studier er det dokumentert dårlig kardiovaskulær risikofaktorkontroll og høy forekomst av nye hjerte- og karhendelser hos hjerteinfarktpasienter. Det foreligger lite kunnskap om omfang av sekundærforebyggende behandling og hjerterehabilitering ved norske sykehus. Vi ønsket derfor å gjennomføre en kartlegging av rutiner ved utskrivning og poliklinisk oppfølging etter hjerteinfark ...

This article shows how contemporary artistic practice seeks to re-evaluate, re-interpret and re-imagine (historical) Arctic exploration narratives that have generally been considered gendered and dominated by men. It particularly examines the work of contemporary Norwegian artist Tonje Bøe Birkeland, whose entire practice emerges from embodying and staging imagined turn of the century woman explorers. ...

Unscheduled power disturbances cause severe consequences both for customers and grid operators. To defend against such events, it is necessary to identify the causes of interruptions in the power distribution network. In this work, we focus on the power grid of a Norwegian community in the Arctic that experiences several faults whose sources are unknown. First, we construct a data set consisting of ...

The marine environment is potentially a prolific source of small molecules with significant biological activities. In recent years, the development of new chromatographic phases and the progress in cell and molecular techniques have facilitated the search for marine natural products (MNPs) as novel pharmacophores and enhanced the success rate in the selection of new potential drug candidates. However, ...

It is of considerable benefit to combine information obtained from different satellite sensors to achieve advanced and improved characterization of sea ice conditions. However, it is also true that not all the information is relevant. It may be redundant, corrupted, or unnecessary for the given task, hence decreasing the performance of the algorithms. Therefore, it is crucial to select an optimal ...

Objective - In SLE, smoking increases the burden of cutaneous disease and organ damage, and leads to premature mortality. However, the effect of smoking on disease manifestations and cytokine levels of patients with SLE is unclear. This study compared characteristics of patients with SLE across smoking status, and determined the association of smoking with serum cytokine levels.<p> <p>Method - A ...

In this study, we use low-coverage shotgun sequencing of genomic DNA, commonly referred to as genome skimming, to investigate the phylogenetic relationships of the fungus gnat genus Allodia Winnertz (Mycetophilidae, Mycetophilinae, Exechiini). Nineteen specimens, representing 16 in-group and three outgroup taxa, were successfully sequenced and molecular markers of both mitochondrial and nuclear ...

Leve hele livet er en kvalitetsreform for eldre. Målet med den er at alle eldre skal få bedre hjelp og støtte til å mestre livet. Reformen handler om de grunnleggende tingene som oftest svikter i tilbudet til eldre: mat, aktivitet og fellesskap, helsehjelp og sammenheng i tjenestene.<p> <p>Senter for omsorgsforskning har utarbeidet denne og flere kunnskapsnotater på oppdrag fra Helsedirektoratet. ...
