Exploring trophic niches and parasite communities of sympatric Arctic charr and brown trout populations of southern Norway

Catchment-scale variation between lake habitats has the potential to simultaneously influence the trophic niche and parasite community of fish hosts. In this study, we investigated the trophic niche and parasite community of sympatric Arctic charr and brown trout populations from two inter-connected southern Norwegian lakes at different altitudes. Arctic charr and brown trout occupied profundal an

Transaction costs of the zakat institution : An open innovation approach

This paper examines transaction costs in the institutional zakat system from the open innovation perspective and tries to understand its impact on performance. It attempts to harmonise the concept of transaction costs with the open innovation strategy, especially in the aspect of zakat distribution. A quantitative approach was applied in measuring the performance of zakat distribution, where the d

Doctoral supervision in theory and practice

This is a long-awaited book that contributes to the professional development of doctoral supervisors and provides an indepth perspective on doctoral students’ learning. Well anchored in current research, the authors discuss the organisation of Swedish doctoral education, the supervisor’s professional practice, doctoral students’ learning, and the quality system of this education in Sweden.The conn

Evaluating Nutrient Reduction, Grazing and Barley Straw as Measures Against Algal Growth

The aim of our study was to experimentally investigate whether it is possible to reduce nuisance growth of filamentous algae in freshwater ecosystems. We used an experimental set-up mimicking a shallow pond system and performed a field investigation in the eutrophic moat of Krapperup castle (Southern Sweden), which exemplifies an extremely impaired ecosystem with ample growth of filamentous green

Early Cambrian Syenite and Monzonite Magmatism in the Southeast of the East European Platform : Petrogenesis and Tectonic Setting

Abstract—The paper reports new geochronological, petrological, and isotope-geochemical data on the syenites and alkali syenites of the Artyushki massif, and the monzonites of the Gusikha massif. These massifs are located along the southwestern and northeastern margins of the Pachelma aulacogen, in the southeastern part of the East European Platform (EEP). They have Early Cambrian ages of 524 ± 3 (

The effects of Cernitin® on inflammatory parameters and benign prostatic hyperplasia : An in vitro study

The pollen extract Cernitin® is widely used for treatment of benign prostatic hyperplasia (BPH) and non-bacterial chronin prostatitis. However, little is known about the underlying molecular mechanisms to explain the clinical effects of Cernitin®. In this study, we sought to investigate the cellular mechanisms by which Cernitin® induces its effects on human prostatic cell lines BPH-1 and WPMY-1 an

Plasma exchange or immunoadsorption in patients with rapidly progressive crescentic glomerulonephritis. A Swedish multi-center study

A therapeutic removal of antibodies may be achieved by immunoadsorption (IA) or by plasma exchange (PE). The aim of this prospective randomised study was to compare the efficacy of these different techniques with regard to treatment of patients with rapidly progressive glomerulonephritis (RPG) having at least 50% crescents. Forty-four patients with a RPG were included for treatment either by IA or

Proenkephalin a 119-159 (penKid) - a novel biomarker for acute kidney injury in sepsis : an observational study

Background: Sepsis is a leading cause of death worldwide and a major challenge for physicians to predict and manage. Proenkephalin A 119-159 (penKid) is a reliable surrogate marker for the more unstable endogenous opioid peptide enkephalin, which has previously been shown to predict both acute and chronic kidney disease. The aim of this prospective observational study was to assess penKid as a pre

Ideological struggle over epistemic and political positions in news discourse on migrant activism in Sweden

The specific aim of this study is to investigate how a group of migrant rights activists in Sweden are positioned in news discourse. The more general aim of this study is to understand the conditions under which activists participate within news discourse. Through a critical discourse analytical (CDA) framework, with specific focus on the use of epistemic and dynamic modalities in the presentation

Evaluation of eight high spatial resolution gridded precipitation products in Adige Basin (Italy) at multiple temporal and spatial scales

This study provides a comprehensive evaluation of eight high spatial resolution gridded precipitation products in Adige Basin located in Italy within 45–47.1°N. The Adige Basin is characterized by a complex topography, and independent ground data are available from a network of 101 rain gauges during 2000–2010. The eight products include the Version 7 TRMM (Tropical Rainfall Measuring Mission) Mul

An Improved Spatial Downscaling Procedure for TRMM 3B43 Precipitation Product Using Geographically Weighted Regression

Precipitation data at high spatio-temporal resolution are essential for hydrological, meteorological, and ecological research in local basins and regions. The coarse spatial resolution (0.25°) of Tropical Rainfall Measuring Mission (TRMM) 3B43 product is insufficient for practical requirements. In this paper, a multivariable geographically weighted regression (GWR) downscaling method was developed

Search for doubly charged Higgs bosons in multi-lepton final states with the ATLAS detector

Standard Model events with prompt, isolated, same-charge high-pT leptons are rare, and therefore events with such final states provide a powerful signature towards new discoveries. This thesis presents two searches for doubly charged Higgs bosons decaying into same-charge lepton pairs using proton–proton collision data recorded by the ATLAS detector at the LHC. Observation of doubly charged Higgs

From population to production : 50 years of scientific literature on how to feed the world

How to feed the world is a vigorously debated question, but the extent to which possible solutions receive attention in the scientific literature has not been studied. Using textual analysis, we analyse 12,640 research articles to quantify how this discourse evolved over the last 50 years, distinguishing between a focus on three potential levers: total food production, per capita food demand, and

Connecting Air Pollution Exposure to Socioeconomic Status : A Cross-Sectional Study on Environmental Injustice among Pregnant Women in Scania, Sweden

Environmental injustice, characterized by lower socioeconomic status (SES) persons being subjected to higher air pollution concentrations, was explored among pregnant women in Scania, Sweden. Understanding if the general reduction of air pollution recorded is enjoyed by all SES groups could illuminate existing inequalities and inform policy development. "Maternal Air Pollution in Southern Sweden",

Knowledge diversities and group dynamics within international master programs

Although international students are allowed to study at Swedish universities since 1985, the Swedish university landscape has undergone a strategic internationalization mainly during the recent few years. With a steadily growing number of international master programs and thereby more international students being part of the Swedish education system, a variety of problems related to cultural-diver

Strain improvement of Escherichia coli K-12 for recombinant production of deuterated proteins

Deuterium isotope labelling is important for structural biology methods such as neutron protein crystallography, nuclear magnetic resonance and small angle neutron scattering studies of proteins. Deuterium is a natural low abundance stable hydrogen isotope that in high concentrations negatively affect growth of cells. The generation time for Escherichia coli K-12 in deuterated medium is substantia

Flexibility and context specificity of communicative rhythmic behaviours in chimpanzees

Rhythmic behaviors (in short RBs), such as applauding, dancing or rocking a baby to sleep are part of humans everyday life. Recently there has been a growing interest in the RBs of other species, as a way of tracking the evolutionary roots of human musicality. RBs have been initially studied in arthropods, insects, anurans and songbirds, where a single behaviour is tied to reproductive function. E
