Invariant yields of neutral pions at midrapidity in the transverse momentum range 0.6 < pT < 12 GeV/c measured in Pb-Pb collisions at root(NN)-N-s = 2.76 TeV are presented for six centrality classes. The pp reference spectrum was measured in the range 0.4 < pT < 10 GeV/c at the same center-of-mass energy. The nuclear modification factor, R-AA, shows a suppression of neutral pions in central Pb-Pb
Popular Abstract in Swedish Det är ofta fördelaktigt att i olika sammanhang representera våra observationer av verkligheten med en följd av tal. Så skilda exempel som ljud, bilder, hjärnvågor, havsvattenvågor, jordbävningar och aktiekurser kan låta sig beskrivas av följder av tal. Man kan med fördel föreställa sig följden som en uppritad graf, där den horisontella axeln beskriver tidpunkten för mäThe theory of stochastic time-frequency analysis of non-stationary random processes has mostly been developed for processes in continuous time. In practice however, random processes are observed, processed, and interpreted at a finite set of time points. For processes in continuous time, the ambiguity domain has interesting properties which makes it particularly useful. One such property is that t
Popular Abstract in Swedish Emotionell stress samt hårt fysiskt arbete reducerar blodflödet till tarmen. Om cirkulationen till tarmen är kraftigt reducerat under en längre period får tarmen syrebrist, den blir ischemisk. Vid ischemi bildas skadliga slaggprodukter vilka distribueras till andra organ när blodflödet ökar igen. Irritable bowel syndrome, IBS, är en vanlig mag-tarm sjukdom som man inte Psychological distress or physical strain lead to reduced blood flow in the intestine since other organs are prioritised. One aim of this thesis was to investigate how ischemia followed by reperfusion affects the large intestine and the enteric nervous system (ENS). To do so an experimental ischemia/reperfusion (I/R) model was set up using rat large intestine. In order to study how the ENS reacts
Recent studies suggest that vortex ring formation during left ventricular (LV) rapid filling is an optimized mechanism for blood transport, and that the volume of the vortex ring is an important measure. However, due to lack of quantitative methods, the volume of the vortex ring has not previously been studied. Lagrangian Coherent Structures (LCS) is a new flow analysis method, which enables in vi
Popular Abstract in Swedish Skolämnet livskunskap har vuxit fram i svenska skolor under det senaste decenniet, ofta utifrån en ambition att främja hälsa och att konkretisera skolans värdegrundsarbete. Avhandlingen belyser hur livskunskap växer fram och definieras som ett skolämne i nationella och kommunal dokument, och organiseras i lokal skolpraktik. Studien, som har en kombinerad barndomssocioloThe aim of this thesis is to understand and cast light over how the school subject Life Competence Education (Sw. Livskunskap) is developing in the Swedish school context. In focus of the study is how this school subject is defined and organized by actors (i.e. politicians, national governmental institutes, local governmental authorities, teachers and children in compulsory schools) in the differe
Recension av tidskriften OEIs temanummer om papper.
We report the characterization of three novel human papillomavirus (HPV) types of the genus Gammapapillomavirus. HPV175 and HPV180 were isolated from a condyloma. HPV178 was isolated from healthy skin adjacent to an actinic keratosis.
The article may be seen as a sequel to my paper delivered at a conference on art historical subjectivity and methodology in Stockholm 1999, initiated by Margaretha Rossholm Lagerlöf. – Now I will try to move that analysis a little step further by discussing some problems concerning the more explicit performative effects and experiences of everyday technical objects and their occasionally strange v
Flame spread in textile materials was modelled using two different simulation programs: the semi-empirical area-based code ConeTools, and the computational fluid dynamics, CFD, code Fire Dynamics Simulator, FDS, (version 5). Two textile products developed within the EU-project Flexifunbar were selected for study. The two products show a large difference in composition and application area, one mat
I antologin får du ta del av sju olika analyser av det utmanande arbetet med att åstadkomma inriktning och samordning av samhällets resurser i samband med skogsbranden. Publikationen är ett utvecklingsbidrag och är tänkt att ge vägledning till förbättrad förmåga att hantera framtidens samhällsstörningar. Bakom texterna står sju olika författare som utgått från ambitionen att publicera ett transp
Simultaneous two-species imaging using single-shot planar laser-induced fluorescence have been performed to record high quality image pairs of CH/OH, CH/CH2O and OH/CH2O to visualize the flame front structures in swirl-stabilized lean premixed methane/air flames. The results show that the investigated flames exhibit various flame front structures distinctly in space, which covers: (1) the corrugat
Background - This interim 12-month analysis is a part of an open-label, observational, prospective study on health outcomes and cost impact of levodopa/carbidopa intestinal gel (LCIG, Duodopa) in Parkinson disease (PD). The specific aim was to investigate clinical and health-related quality of life (HRQoL) effects in routine care. Methods - Unified PD rating scale (UPDRS) was the primary efficacy
Background: Esophagus cancer (EC) is among the five most common cancers in both sexes in Iran, with an incidence rate well above world average. Social rank (SR) of individuals and regions are well-known independent predictors of EC incidence. The aim of current study was to assess gender and social disparities in EC incidence across Iran's provinces through 2003-2009. Materials and Methods: Data o
A complete reliability study of the DC and RF characteristics for InGaAs nMOSFETs with aluminium oxide/ hafnium oxide dielectric is presented. The main stress variation at high frequencies is related to a threshold voltage shift, whereas no decrease is found in the maximum of the cut-off frequency and RF-transconductance. Constant gate stress leads to a charge build up causing a threshold voltage
Much of global passenger transport is linked to tourism. The sector is therefore of interest in studying global mobility trends and transport-related emissions. In 2005, tourism was responsible for around 5% of all CO(2) emissions, of which 75% were caused by passenger transport. Given the rapid growth in tourism, with 1.6 billion international tourist arrivals predicted by 2020 (up from 903 milli
Recent studies have identified mutations in the complement regulatory gene factor I (CFI) that predispose to atypical hemolytic uremic syndrome (aHUS). CFI is a two-chain serine protease in which the light chain carries the catalytic domain while the heavy chain's function is unclear. It downregulates the alternative and classical complement pathways by cleaving the alpha' chains of C3b and C4b in
We show that coherent anti-Stokes Raman lineshapes do not follow known spectral profiles if the time asymmetry of realistic laser pulses is taken into account. Examples are given for nanosecond and picosecond laser pulses commonly employed in frequency-resolved coherent anti-Stokes Raman scattering. More remarkably, the analysis suggests an effect of line narrowing in comparison to the customary a
