The present study uses RSM (Response Surface Methodology) to verify the fusibility of bottom ash from coal industry, and efficient flux between, calcium oxide (CaO), lithium oxide (Li2O) and sodium oxide (Na2O). The bottom ashes,have demonstrated the possibility to be used in the development of glass-ceramics, and glassy materials, due to the presence of high concentrations of aluminum silicates.
The impact of climate variability on water demand and availability in drylands is substantial. Establishing methods to analyse precipitation (P) and evapotranspiration data sets may generate useful tools that assist in drought recognition and regional variations therein. The authors developed an index that simultaneous integrates both these variables in climate variability analysis. This study pro
Background: Data from biological samples and medical evaluations plays an essential part in clinical decision making. This data is equally important in clinical studies and it is critical to have an infrastructure that ensures that its quality is preserved throughout its entire lifetime. We are running a 5-year longitudinal clinical study, KOL-Örestad, with the objective to identify new COPD (Chro
Flying insects frequently navigate through environments of different complexity. In this study, buff-tailed bumblebees (Bombus terrestris L.) were trained to fly along tunnels of different widths, from 60 to 240 cm. In tunnel widths of 60 and 120 cm, bumblebees control their lateral position by balancing the magnitude of translational optic flow experienced in the lateral visual field of each eye.
What are the pedagogical impacts of internationalisation on the development of higher education in Europe? How can we proceed in this process and take a pedagogical stance on the issue? This theoretical article is partly based on a series of empirical studies, conducted by the author, investigating students' and teachers' experiences and understanding of an internationalised educational context in
Background Registry studies and case-control studies have demonstrated that the risk of acute myocardial infarction (AMI) is increased following influenza infection. Small randomized trials, underpowered for clinical end points, indicate that future cardiovascular events can be reduced following influenza vaccination in patients with established cardiovascular disease. Influenza vaccination is rec
A negative educational gradient has been found for many causes of death. This association may be partly explained by confounding factors that affect both educational attainment and mortality. We correct the cause-specific educational gradient for observed individual background and unobserved family factors using an innovative method based on months lost due to a specific cause of death re-weighted
Introduction Re-ablement services are in a period of strong development, but the terms and definitions used remain unclear, and the scientific evidence is still weak. The aim of this systematic review was to obtain an overview of the scientific literature in this evolving research area, and investigate whether there is scientific evidence for positive effects of re-ablement services for older comm
Over the last couple of decades an increasing use of temporary organizations has been observed in public administration, a development sometimes referred to as projectification. This article explores the political-administrative rationality of pro- jectification by studying the initiation and implementation of a project funding system regarding social investments in a Swedish municipality.

A high and stable seed production of both organic and conventional white clover (Trifolium repens L.) is needed to meet market requirements. Seed yields of white clover are, however, known to vary greatly, and organic yields are often considerably lower than conventional yields. Our aim in this study was to estimate the roles of pollinators, pests and different yield components for organic and con
The highly eroded 23 km diameter Rochechouart impact structure, France, has extensive evidence for post-impact hydrothermal alteration and sulphide mineralisation. The sulphides can be divided into four types on the basis of their mineralogy and host rock. They range from pyrites and chalcopyrite in the underlying coherent crystalline basement to pyrites hosted in the impactites. Sulphur isotopic
Background: The causes and effects of anastomotic leakage after anterior resection are difficult to study in small samples and have thus been evaluated using large population-based national registries. To assess the accuracy of such research, registries should be validated continuously. Material and methods: Patients who underwent anterior resection for rectal cancer during 2007–2013 in 15 differe
This thesis investigates how regulatory instruments, and specifically requirements rules, targeting energy use in existing residential buildings could be made part of the forceful intervention that is required to reduce the use of energy in existing residential buildings. Two approaches to the design of requirement rules are analyzed: a detail-steering approach and a target-oriented approach. The
