The Gaia-ESO Survey : The present-day radial metallicity distribution of the Galactic disc probed by pre-main-sequence clusters

Context. The radial metallicity distribution in the Galactic thin disc represents a crucial constraint for modelling disc formation and evolution. Open star clusters allow us to derive both the radial metallicity distribution and its evolution over time. Aims. In this paper we perform the first investigation of the present-day radial metallicity distribution based on [Fe/H] determinations in late

Ökad kunskap om familjärt melanom och de bakomliggande generna

Approximately 5-10 % of all melanoma patients have close relatives with melanoma. 5-20% of melanoma families have germline mutations in the CDKN2A gene. Swedish CDKN2A mutation carriers have a young median age of onset of melanoma, increased risks of multiple primary melanoma and of tobacco-associated cancers in respiratory and upper digestive tissues, and also worse survival compared to non-carri

A National Swedish Longitudinal Twin-Sibling Study of alcohol use disorders among males

Aims: To examine whether genetic influences on the development of alcohol use disorders (AUD) among men during emerging adulthood through mid-adulthood are stable or dynamic. Design: A twin study modeling developmental changes in the genetic and environmental influences on AUD during three age periods (18-25, 26-33 and 33-41) as a Cholesky decomposition. Setting: Sweden. Participants: Swedish male

Punk Shamanism, revolt and break-up of traditional linkage : The waves of cultural production in post-Soviet Kazakhstan

This article analyses new waves of cultural production in the late Soviet and post-Soviet period. It focuses on contemporary artists’ self-perception and self-positioning in the new realities of the postsocialist cultural realm and national awakening discourses. Independent contemporary artists of the post-Soviet period form new artistic movements, such as Punk Shamanism in Kazakhstan, to produce

On the missing link in ecology : Improving communication between modellers and experimentalists

Collaboration between modellers and experimentalists is essential in ecological research, however, different obstacles linking both camps often hinder scientific progress. In this commentary, we discuss several issues of the current state of affairs in this research loop. Backed by an online survey amongst fellow ecologists, modellers and experimentalists alike, we identify two major areas that ne

PreHospital Ambulance Stroke Test - pilot study of a novel stroke test

Background: There is a need for a prehospital stroke test that in addition to high sensitivity for stroke, also is able to communicate stroke severity similar to the National Institute of Health Stroke Scale (NIHSS). Methods: The PreHospital Ambulance Stroke Test (PreHAST), an eight item test based on NIHSS, which scores stroke severity from 0-19 points, was designed and adapted for the ambulance

Biodiversity conservation requires an understanding of the extent to which a landscape can contribute to species life-cycle. Conceived as a dynamic mosaic of spatial units with different properties, landscape is a very relevant scale for dealing with biodiversity issues. This paper aims at analysing the relationships and overlapping between this geography and landscape ecology as two scientific fi

Protecting the Environment in Relation to Armed Conflict - The Role of Multilateral Environmental Agreements

This thesis examines how environmental treaties, also referred to as multilateral environmental agreements (MEAs), can enhance the protection of the environment during armed conflicts of both international and non-international character. The examination also covers the immediate aftermath of armed conflicts. Most of the previous research has focused on the application of the law of armed conflict

Multifractal analysis of some multiple ergodic averages

In this paper we study the multiple ergodic averages, on the symbolic space σm = (0,1,...,m-1}N* where m≥ 2, ℓ ≥ 2, q≥ 2 are integers. We give a complete solution to the problem of multifractal analysis of the limit of the above multiple ergodic averages. Actually we develop a non-invariant and non-linear version of thermodynamic formalism that is of its own interest. We study a large class of mea
