In this paper a three dimensional FE model of the friction stir welding (FSW) is presented and the FSW process is simulated. The model has been implemented in FE code Abaqus with user subroutines DLOAD, DFLUX and UMASFL. The material data used to describe the welded panels is from an aluminium alloy called AL-2024-T3 and the material is assumed to be isotropic with temperature dependent yield stre
Aim: Acute otitis media (AOM) is a common childhood disease, which often becomes recurrent (rAOM). A small reduction of AOM episodes has been noted in unselected child cohorts after vaccination with heptavalent conjugate pneumococcal vaccine (PCV7). The purpose of this study was to investigate how vaccination affects young children at risk of developing rAOM. Methods: Ninety-six children with an A
Radiation therapy is a major treatment modality for malignant and benign brain tumors. Concerns of radiation effects on the brain tissue and neurocognitive function and quality of life increase as survival of patients treated for brain tumors improves. In this article, the clinical and neurobehavioral symptoms and signs of radiation-induced brain injury, possible histopathology, and the potential

In this paper, the purpose is to illustrate how organised actors within an international business environment manage to integrate conflicting perspectives on growth and corporate social responsibility (CSR). An empirical study of sustainable fishing in Britain between 2002 and 2005 illustrates how different organisations succeed in creating a shared meaning on sustainability and CSR among the part
An upper bound on the average error probability for maximum-likelihood decoding of the ensemble of randomL-branch binary trellis codes of rateR = 1/nis given which separates the effects of the tail lengthTand the memory lengthMof the code. It is shown that the bound is independent of the lengthLof the information Sequence whenM geq T + [nE_{VU}(R)]^{-1} log_{2} L. The implication that the actual e
BACKGROUND: Normal cell division is coordinated by a bipolar mitotic spindle, ensuring symmetrical segregation of chromosomes. Cancer cells, however, occasionally divide into three or more directions. Such multipolar mitoses have been proposed to generate genetic diversity and thereby contribute to clonal evolution. However, this notion has been little validated experimentally. PRINCIPAL FINDINGS:
It is demonstrated that an accurate approximation of the screening function is crucial for a quantitative evaluation of the XPS asymmetry index α. It is also shown that the dynamical aspects of the valence electron response are important in order to get an accurate description of the XPS spectrum at finite distances from the threshold.(23 refs)
A central challenge to gender studies during the last 15 years has been the expanding field of intersectionality. The use of intersectional perspectives within working life research has explored how class, sexuality, and race difference affected women’s position in the labor market. The aim of this article is to argue for the need of including an intersectional perspective in the field of working
Aim: The aim of the study was to translate and validate the PADQLQ (Pediatric allergic disease quality of life questionnaire), a disease specific quality of life questionnaire for the assessment of quality of life in children with pollen allergy. Methods: The PADQLQ was translated into Swedish according to guidelines. Children 7-18 years with grass pollen allergy were included. Quality of life was
t is well known that overweight/obesity are risk factors for several important conditions of internal medicine. The positive correlation between gonarthrosis and a high BMI is also well investigated. However, the possible correlation between owerweight/obesitas and other orthopaedic conditions are less well studied and are therefore rarely discussed in either medical terms or economical considerat
Rationale:The innate immune system and in particular the pattern-recognition receptors Toll-like receptors have recently been linked to atherosclerosis. Consequently, inhibition of various signaling molecules downstream of the Toll-like receptors has been tested as a strategy to prevent progression of atherosclerosis. Receptor-interacting protein 2 (Rip2) is a serine/threonine kinase that is invol
