Preparation and characterization of nanometer-thin freestanding polymer foils for laser-ion acceleration

We report on the production and characterization of polymer-based ultra-thin (sub 10 nm) foils suited for experiments on laser-ion acceleration in the regime of radiation pressure acceleration. Beside the remarkable mechanical stability compared with commonly used diamond-like-carbon foils, a very homogeneous layer thickness and a small surface roughness have been achieved. We describe the technic

Towards an understanding of fatigue in Parkinson's disease.

OBJECTIVES: To gain an improved understanding of fatigue in Parkinson's disease (PD) by exploring possible predictors among a wide range of motor and non-motor aspects of PD. METHODS: 118 consecutive PD patients (54% men; mean age, 64 years) were assessed regarding fatigue, demographics and a range of non-motor and motor symptoms. Variables significantly associated with fatigue scores in bivariate

Search for one large extra dimension with the DELPHI detector at LEP

Single photons detected by the DELPHI experiment at LEP2 in the years 1997-2000 are reanalysed to investigate the existence of a single extra dimension in a modified ADD scenario with slightly warped large extra dimensions. The data collected at centre-of-mass energies between 180 and 209 GeV for an integrated luminosity of similar to 650 pb(-1) agree with the predictions of the Standard Model and

Yu-Shiba-Rusinov states in phase-biased superconductor-quantum dot-superconductor junctions

We study the effects of a phase difference on Yu-Shiba-Rusinov (YSR) states in a spinful Coulomb-blockaded quantum dot contacted by a superconducting loop. In the limit where charging energy is larger than the superconducting gap, we determine the subgap excitation spectrum, the corresponding supercurrent, and the differential conductance as measured by a normal-metal tunnel probe. In absence of a

Genetic factors in childhood cancer. Associations between tumors in childhood and adulthood, and prevalence of germline TP53 mutations

Popular Abstract in Swedish Varje år insjuknar omkring 300 barn i cancer. Förbättrade behandlingsmetoder under de senaste decennierna har lett till att mer än tre av fyra barn idag faktiskt botas från sin sjukdom. Tyvärr drabbas en stor andel av de som överlever sin cancer av så kallade sena komplikationer till följd av den tuffa behandling de har utsatts för. Bland annat har man sett en livslång The etiology of childhood cancer is largely unknown. Approximately 1-10% of all childhood tumors are associated with known cancer predisposition syndromes. However, the contribution may be underestimated due to the failure to detect patients with genetic susceptibility for cancer when relying on known family pattern and anomalies. Growing evidence indicates that patients with genetic susceptibilit

Religion och etnicitet

Religionssociologi är ett brett ämnesområde som belyser de sociala funktionerna av religion i dåtid likväl som i nutid. En av de nutida viktiga aspekterna av religionens sociala natur är dess förhållande till etnicitet. Etnicitet har under den senare delen av 1900-talet varit ett framträdande sätt att kategorisera grupper. Samtidigt har det framförts tankar om att denna form av social kategoriseri

Anti-TNF treatment of chronic arthritis in clinical practice. New assessment method and predictors of efficacy and tolerability.

Abstract Treatment of chronic inflammatory arthritis has undergone major changes over the past years following introduction of targeted biological therapies. Tumour necrosis factor (TNF) blocking therapy has been the most important biological treatment of chronic arthritis to date. The overall objective of this thesis was to develop a new assessment method of efficacy of biological therapy in clin

The complex use of religion in decisions on organ transplantation.

Because of its existential character, organ transplantation is strongly connected to a person's view of life. This article describes how participants in a focus group use religious elements in decision-making on transplantation medicine in four European countries. Further these findings are related to two influential theologians: James Gustafson and Paul Ramsey, and their thinking on the role of r

Experimental and theoretical investigation of non-isothermal transfer in hygroscopic building materials

In this paper a modified two-dimensional Luikov model for evaluating the non-isothermal moisture migration in porous building materials was proposed. The coupled heat and moisture transfer problem was modeled. Vapor content and temperature were chosen as the principal driving potentials. The coupled equations were solved by a numerical method, which consists of a finite difference technique with a

Application of Control Theory to a Commercial Mobile Service Support System

The Mobile Service Support system (MSS), which Ericsson AB develops, handles the setup of new subscribers and services into a mobile network. Experience from deployed systems show that traffic monitoring and control of the system will be crucial for handling overload situations that may occur at sudden traffic surges. In this paper we identify and explore some important control challenges for this

Contact allergy to textile dyes. Clinical and experimental studies on disperse azo dyes

Disperse dyes are the most common allergens among textile dyes. It is not known whether the purified dyes, impurities in the commercial dyes, or metabolites are the actual sensitisers. Moreover, it is not known whether those disperse dyes that are now present in test series are actually used in textile dyeing today. The aim of this thesis was A) to evaluate the significance of the impurities foun

Brevican distinctively assembles extracellular components at the large diameter nodes of Ranvier in the CNS

Brevican is known to be an abundant extracellular matrix component in the adult brain and a structural constituent of perineuronal nets. We herein show that brevican, tenascin-R (TN-R) and phosphacan are present at the nodes of Ranvier on myelinated axons with a particularly large diameter in the central nervous system. A brevican deficiency resulted in a reorganization of the nodal matrices, whic

Array based genetic profiling of chronic lymphocytic leukemia

Although no common genetic defect has been described in chronic lymphocytic leukemia (CLL), recurrent genomic aberrations (i.e. deletions of chromosome 11q, 13q, 17p and trisomy 12) are important for prognostication. Deletion of 13q as single aberration is associated with the best prognosis, whereas del(11q) and del(17p) predict a poor outcome. Recent development of high-resolution genomic techniq

Basic Concepts for Convection Parameterization in Weather Forecast and Climate Models: COST Action E50905 Final Report

The research network "Basic Concepts for Convection Parameterization in Weather Forecast and Climate Models" was organized with European funding (COST Action E50905) for the period of 2010-2014. Its extensive brainstorming suggests how the subgrid-scale parameterization problem in atmospheric modeling, especially for convection, can be examined and developed from the point of view of a robust theo

Complement activation in thrombotic microangiopathy.

The endothelium lining the vascular lumen is continuously exposed to complement from the circulation. When erroneously activated on host cells, complement may generate a deleterious effect on the vascular wall leading to endothelial injury, exposure of the subendothelial matrix and platelet activation.In this review the contribution of complement activation to formation and maintenance of the path

Klassrummet som muntlig arena. Att bygga och etablera ethos.

Popular Abstract in Swedish Ett grundantagande för avhandlingen Klassrummet som muntlig arena. Att bygga och etablera ethos är att en människa som med trovärdighet vill kunna verka som en demokratisk medborgare i olika kommunikationssituationer måste besitta kommunikativ kompetens. Följaktligen hänger demokrati och kommunikativ kompetens tätt samman. En viktig trovärdighetsfaktor i sammanhanget ärThe Class Room as an Oral Arena: Building and Establishing Ethos starts with the premise that every person who wants to act credibly as a democratic citizen must have a communicative competence. Democracy and communicative competence are closely linked. To communicate credibly is to communicate with ethos. The purpose of this dissertation is to study how students in Swedish gymnasium build and est

Assessing the risk of N leaching from forest soils across a steep N deposition gradient in Sweden.

Nitrogen leaching from boreal and temporal forests, where normally most of the nitrogen is retained, has the potential to increase acidification of soil and water and eutrophication of the Baltic Sea. In parts of Sweden, where the nitrogen deposition has been intermediate to high during recent decades, there are indications that the soils are close to nitrogen saturation. In this study, four diffe
