Noncollinear optical gating

We present a novel scheme for high-order harmonic generation, enabling the production of spatially separated isolated attosecond pulses. This can be achieved by driving the generation process with two identical, but temporally delayed laser pulses, which are noncollinearly overlapping in the generation medium. Our approach provides intense attosecond pulses directly separated from the fundamental

The Swedis Ne Bis in Idem Saga - Painting a multi-layered picture

The primary aim of the article is to examine the sum of the three Swedish judgments of 2013 that was handed down after the ECJ's judgment in the Åkerberg Fransson-case. The examination is done against the backdrop of the legal developments preceding these judgments, with a particular attention to how different layers of law are perceived and given effect in the national legal order.

Environmental assessment and scenario analysis of sugar beet transport in Scania, Sweden

The aim was to assess the environmental sustainability of sugar beet transport in Scania, Sweden—estimating lorry travel distances, fuel use and air emissions. Scenario analyses measuring the same parameters for switching to newer vehicle types and differing ratios of biodiesel were also performed. The method applied for distance calculations was a GIS-based proximity analysis. Results revealed th

Digital Materialities and Family Practices : The Gendered, Practical, Aesthetical and Technological Domestication of Play

Digital gameplay is now firmly embedded in everyday practices in many Scandinavian homes. This paper deals with the constitution of such practices in families by taking a closer look at the material objects essential to play and their role in the “design of everyday life” (Shove et al 2007). It uses ethnographic method and anthropological practice theory to attend to the domestic spaces of leisure

Numerical Simulation of Unsteady Flows of Physiological Relevance

Pulsatile flows in geometries of physiological relevance have been investigated. Atherosclerotic plaques are (initiated) near junctions and bifurcations in larger arteries. The flow in these regions is characterized by flow separation and unsteadiness, which indicates that local flow conditions contribute to atherogenesis. Flows in curved and bifurcating pipes have been investigated over many y

The Effects of Innovativeness on Effectiveness and Efficiency

Purpose – Whilst researchers have explored the relationship between innovativeness and business performance in different organizations, such studies in services such as restaurants are scarce. The purpose of this paper is to examine potential influences of innovativeness on effectiveness and efficiency and their subsequent effects on restaurant business performance. Design/methodology/approach –

Waveform Characterization of Atrial Fibrillation Using Phase Information

A novel method for characterization of f-wave morphology in atrial fibrillation (AF) is presented. The method decomposes atrial activity into fundamental and harmonic components, dividing each component into short blocks for which the amplitudes, frequencies, and phases are estimated. The phase delays between the fundamental and each of the harmonics, here referred to as harmonic phase relationshi

Blueberry husks, rye bran and multi-strain probiotics affect the severity of colitis induced by dextran sulphate sodium

Objective. The enteric microbiota is a pivotal factor in the development of intestinal inflammation in humans but probiotics, dietary fibres and phytochemicals can have anti-inflammatory effects. The aim of this study was to evaluate the therapeutic effect of multi-strain probiotics and two conceivable prebiotics in an experimental colitis model. Material and methods. Sprague-Dawley rats were fed

NiFe2O4 and Fe3O4 studied by XMCD and resonant photoemission

X-ray magnetic circular dichroism and resonant photoemission at the Fe and Ni L-2,L-3 edges have been used to investigate the electronic structure of NiFe2O4 (NFO) thin films. The results, when compared to those obtained on Fe3O4, indicate that in a 12 nm NFO film the Ni atoms occupy mainly B sites, as in bulk NFO, and that a decrease in the thickness of the film results in a modi. cation of the n

Common Variants Within Oxidative Phosphorylation Genes Influence Risk of Ischemic Stroke and Intracerebral Hemorrhage

Background and Purpose-Previous studies demonstrated association between mitochondrial DNA variants and ischemic stroke (IS). We investigated whether variants within a larger set of oxidative phosphorylation (OXPHOS) genes encoded by both autosomal and mitochondrial DNA were associated with risk of IS and, based on our results, extended our investigation to intracerebral hemorrhage (ICH). Methods-

Impact on allergic immune response after treatment with vitamin A

Background: Vitamin A may have some influence on the immune system, but the role in allergy modulation is still unclear. Objective: To clarify whether high levels of retinoic acid (RA) affects allergic response in vivo, we used a murine experimental model of airway allergic disease. Methods: Ovalbumin (OVA)-immunization/OVA-challenge (OVA/OVA) and house dust mite (HDM)-immunization/HDM-challenge (

Natural Transfer of Viable Microbes in Space from Planets in the Extra-Solar Systems to a Planet in our Solar System and Vice-Versa

We investigate whether it is possible that viable microbes could have been transported to the Earth from planets in extra-solar systems by means of natural vehicles such as ejecta expelled by comets or asteroid impacts on such planets. The probabilities of close encounters with other solar systems are taken into account as well as the limitations of bacterial survival times inside ejecta in space,

The influence of temporal distance on justice and care morality.

The primary goal of this study was to examine whether changes in the temporal distance of a moral dilemma affect how it is perceived and subsequently resolved. Based on Construal Level Theory (Trope & Liberman, 2003), it was predicted that the relative weight of abstract justice features should increase and the relative weight of concrete care features should decrease with temporal distance. T

Genetic and Epigenetic Characterisation of Breast Tumours

Popular Abstract in Swedish Bröstcancer är den vanligaste cancerformen bland kvinnor i Sverige. Ungefär var tionde kvinna beräknas drabbas av bröstcancer, och i Sverige insjuknar ungefär 7.000 kvinnor årligen. Glädjande nog har överlevnaden förbättrats och nästan 90% lever 5 år efter sin diagnos och cirka två tredjedelar kan anses botade. Trots detta dör cirka 1.500 kvinnor i sjukdomen i Sverige vBreast tumours harbour a large amount of genetic and epigenetic alterations, which are associated with e.g. tumour aggressiveness, prognosis, and response to therapy. The heterogeneity of breast tumours is reflected in the identification of at least five molecular subtypes named basal-like, luminal A, luminal B, HER2-enriched and normal-like, which are believed to originate from different cell typ

Performance Improvements for the Rasterization Pipeline

Performance improvements are always needed in computer graphics. Better performance frees up computational resources which can be used to increase the level of realism in the rendered images. Despite a very rapid development of graphics hardware, we are still far from the point where photo-realistic rendering can be done in real time. Therefore, better algorithms must be developed in order to adva
