Popular Abstract in Swedish POPULÄRVETENSKAPLIG SAMMANFATTNING PÅ SVENSKA Neuroblastom är en barntumör i nervsystemet som drabbar ungefär 14 barn i Sverige varje år. Neuroblastom uppstår under bildandet av det sympatiska nervsystemet, som är den del av nervsystemet som ansvarar för vår reaktion på fara och stress. Det sympatiska nervsystemet bildas under fosterutvecklingen och de första åren efteNeuroblastoma is a pediatric tumor derived from cells in the sympathetic nervous system. In an attempt to explain the heterogeneous clinical behavior of neuroblastoma tumors, neuroblastomas have been characterized with regard to their degree of sympathetic differentiation. Their expression of genes and proteins that regulate normal sympathetic development and cell cycle/cell death regulators was a

Recently, there has been considerable interest in the internal reforming reactions of solid oxide fuel cells (SOFCs) using methane or natural gas via. The internal reforming and electrochemical reactions appear in the porous anode layer, and may lead to inhomogeneous temperature and gas species distributions according to the reaction kinetics. A three-dimensional calculation method has been furthe

The paper presents an experimental study on heat transfer coefficients in a straight rectangular channel containing continuous transverse ribs. The ribs were located on one side of the channel which is heated with a uniform heat flux. Three values of the rib pitch-to-height ratio (10, 20 and 30) were considered, with the Reynolds number, based on the channel hydraulic diameter, ranging from 57,000

Abstract This paper aims to gain a better understanding of the impact different micro-geometries has on stress distribution in cutting tools. Both principal and effective stress distribution are studied since these quantities have a major impact on the occurrence of damages in the cutting tool such as crack formation, flaking, chipping, breakage and plastic deformation. The development of a stagna

The overall aim of the chapter is to reflect a classroom project on creative learning processes by four “dialogues” between researcher and teacher perspectives on a sequence of themes that lead up to the morale of the tale; Computers and learning, Creativity and education, Creative teaching and Creative learning.

This thesis concerns the analysis of anthropogenic substances of the compound class known as persistent organic pollutants (POPs). Sample preparation perspectives for the analysis of POPs in the environmental matrices water, soils and sediments are presented. This thesis features reasonably cheap and uncomplicated methodology capable of fast screening of POPs. It displays how quantitative extract

The complex interplay by tunneling and scattering in quantum cascade lasers is analyzed with nonequilibrium Green's functions. Data for a recently proposed simple structure based on only two wells per period is presented. This simple structure allows to visualize the relevance of the tunneling resonance very clearly. It is argued that a QCL design needs at least three levels per period, thus furth

A fast 2D motion estimator has been developed and evaluated. The method does not utilize block-matching or iterative solutions and is thus more computationally efficient and suitable for real-time motion estimation over the entire image. The method has been evaluated on 1) phantom measurements and 2) in vivo on the carotid artery wall of 17 subjects, where measurements of the longitudinal displace

Textile exerts various environmental impacts throughout its life cycle. Prevention of textile waste is one means to reduce these impacts. This study seeks to map-out the flow of textile products in the three Nordic Countries – Denmark, Finland and Sweden – from the time they are put on the market until they are discarded. Based on the findings on the flows as well as on the perception of stakehold

The dissertation seeks to problematize the public debate which in recent years has made many people interested in and committed to the region. The empirical basis of the study is some of the regions of southern Sweden which have served as an important platform in the last thirty or forty years when the political and economic establishment has acted and argued in various contexts. The fundamental q

Although Emanuel Swedenborg (1688–1772) is commonly known for his spiritual philosophy, his early career was focused unnatural science. During this period, Swedenborg thought of the world was like a gigantic machine, following the laws of mechanics and geometry. This volume analyzes this mechanistic worldview from the cognitive perspective, by means of a study of the metaphors in Swedenborg’s text

This article seeks to explore how Christian self-understanding has changed as Jewish-Christian relations have enhanced and improved during the last half-century. To what extent are traditional Christological and soteriological models and motifs discussed, defined, redefined, refined or even refuted? Three issues are discussed: the need to (a) go beyond bipolarity (Judaism vis-à-vis Christianity et

This paper examines questionnaire-related issues of variations in the wording of questions and the objective accuracy of the response, in terms of three traffic-related phenomena (accident frequency, incident frequency, and speeding). ca. 900 survey respondents, living along four major arterial streets in Malmö, Sweden, estimated the occurrence of the phenomena in question.
