The Southern Ocean is one of the most productive ecosystems in the world. It is an area heavily dependent on marine primary production and serving as a feeding ground for numerous seabirds and marine mammals. Therefore, the phytoplankton composition and presence of toxic species are of crucial importance. Fifteen monoclonal strains of Pseudo-nitzschia subcurvata, a diatom species endemic to the ...

<i>Aims</i> - Microorganisms play a dichotomous role in the soil nitrogen cycle through mineralization and immobilization. We aimed to understand how nitrogen availability modifies the effect of microorganisms on plant growth. We hypothesized that soil microorganisms would increase plant biomass following amendment with a substrate rich in organic nitrogen (net mineralization), be neutral when adding ...

An optimized low volume sampler was developed to determine both gas- and particle bound concentrations of short and medium-chain chlorinated paraffins (S/MCCPs). Background contamination was limited by the sampler design, providing method quantification limits (MQLs) at least two orders of magnitude lower than other studies within the gas (MQL: 500 pg (ΣSCCPs), 1.86 ng (ΣMCCPs)) and particle (MQL: ...

A new incoherent scatter radar called EISCAT 3D is being constructed in northern Scandinavia. It will have the capability to produce volumetric images of ionospheric plasma parameters using aperture synthesis radar imaging. This study uses the current design of EISCAT 3D to explore the theoretical radar imaging performance when imaging electron density in the E region and compares numerical techniques ...

Denne oppgaven tar for seg utstillingen "Kunstner: Rose-Marie Huuva" som tok sted ved Nordnorsk Kunstmuseum / Davvi Norgga dáiddamusea 5.10.18-29.9.19. Håndverket står sentralt i Huuvas kunstnerskap, og hun både utfordrer og tar vare på flere tusen års samiske tradisjoner. Ikke bare utfordrer hun kunsten, håndverket og duodji-praksisen, men hun initierer også publikum til å stille spørsmål til hva ...

Background - Medical uncertainty is a pervasive and important problem, but the strategies physicians use to manage it have not been systematically described.<p> <p>Objectives - To explore the uncertainty management strategies employed by physicians practicing in acute-care hospital settings and to organize these strategies within a conceptual taxonomy that can guide further efforts to understand ...

This paper shows new contributions in the detection of skin cancer, where we present the use of a customized hyperspectral system that captures images in the spectral range from 450 to 950 nm. By choosing a 7 × 7 sub-image of each channel in the hyperspectral image (HSI) and then taking the mean and standard deviation of these sub-images, we were able to make fits of the resulting curves. These ...

Forecasting energy demand within a distribution network is essential for developing strategies to manage and optimize available energy resources and the associated infrastructure. In this study, we consider remote communities in the Arctic located at the end of the radial distribution network without alternative energy supply. Therefore, it is crucial to develop an accurate forecasting model to ...

Community-based occupational therapy is an increasingly important domain of work for occupational therapists. In Norway, this has been emphasized by the Coordination reform (2012), which assigned municipalities increased responsibility to protect and promote the health of their inhabitants. However, even if approximately 400 positions have been established between 2012 and 2017, little is known ...

With a focus on an under-studied group of immigrants in the UK, this paper examines Iranian families’ language ideologies and practices at home in relation to Persian acquisition and maintenance for their children. Working within a family language policy (FLP) framework, we draw on sociolinguistic data from semi-structured interviews with eighteen mothers to understand how parental beliefs, their ...
