Sea-ice microalgae are a key source of energy and nutrient supply to polar marine food webs, particularly during spring, prior to open-water phytoplankton blooms. The nutritional quality of microalgae as a food source depends on their biomolecular (lipid:protein:carbohydrate) composition. In this study, we used synchrotron-based Fourier transform infra-red microspectroscopy (s-FTIR) to measure the ...

The Sámediggi (Sámi Parliament) in Norway was established in 1989 after the critical juncture of the Alta conflict. As the Indigenous Sámi people are dispersed, a self-determination body with political autonomy was chosen, neither fitting into a territorial nor a non-territorial model of autonomy. We examine how the Sámediggi has developed as an institution for Sámi self-determination, the kind of ...

Egg quality in fishes is commonly determined by fertilisation success and cleavage patterns as a phenotypic outcome of underlying regulatory mechanisms. Although these phenotypic estimators of egg quality are useful in farming conditions, these “good quality” egg batches do not always translate to good larval growth and survival. The identification of genes involved in embryonic development may help ...

The human population is steadily increasing and new alternative protein sources are necessary to secure food safety. There is a growing interest in macroalgae, or seaweed, as an alternative food source as they are rich in nutrients, minerals and carbohydrates. Among the diverse species of macroalga, Palmaria palmata, a red seaweed of growing interest due to its high protein content, represents a ...

The time evolutions of the Bohm sheath and the related pre-sheath are analyzed as an initial value problem. The standard classical fluid model of a collisionless plasma is used with cold ions and Boltzmann distributed electrons. Numerical solutions of the basic equations show that a stationary plasma sheath itself is established within a few ion plasma periods. It is demonstrated analytically that ...

Summary Examining fracture dynamics by socioeconomic status may inform healthcare and prevention. We found a higher risk of hip fracture in men and women with lower educational level in Norway. However, by age 90+years, the cumulative incidence was higher in those with higher education, due to their higher life expectancy.<p> <p>Purpose Socioeconomic gradients are seen for several health outcomes ...

What do we owe to the lazy? On the assumption that the lazy are a paradigmatic case of people who are worse off, when they are through a fault, or choice, of their own, one might suspect that the answer is: not very much. This article shows that this suspicion is simple-minded. Four notions of laziness are distinguished. It is then shown that these notions differ – even from a luck egalitarian ...

Background - Word-finding difficulties are a common self-reported concern in glioma patients known to negatively affect social participation and life satisfaction. Discrepancies between self-reported difficulties and performance on objective tests have been reported, but studies are seldom conducted longitudinally.<p> <p>Aims - The aim of the present study was to examine the occurrence of ...

School dropout may have important negative consequences for the individual as well as for society. Because school grades in lower secondary education are essential for the completion of upper secondary school, remotivating demotivated ninth graders with an increased risk of dropping out seems vital. This study focuses on the experiences of Norwegian ninth grade boys at a learning camp aimed at ...

We aimed to examine whether features of the natural, built and socioeconomic neighbourhood environments were related to depressive symptoms in Australian mid-age and older adults; and whether traffic-related air pollution (TRAP) (NO2) and area-level SES moderated the associations. A total of 4141 of participants (M_age = 61 years) were included in this cross-sectional study. Neighbourhood ...
