Context The evidence that measurement of the common carotid intima-media thickness (CIMT) improves the risk scores in prediction of the absolute risk of cardiovascular events is inconsistent. Objective To determine whether common CIMT has added value in 10-year risk prediction of first-time myocardial infarctions or strokes, above that of the Framingham Risk Score. Data Sources Relevant studies we

This Letter presents a search for high mass e(+)e(-) or mu(+)mu(-) resonances in pp collisions at root s = 7 TeV at the LHC. The data were recorded by the ATLAS experiment during 2010 and correspond to a total integrated luminosity of similar to 40 pb(-1). No statistically significant excess above the Standard Model expectation is observed in the search region of dilepton invariant mass above 110

As our dependence on IT systems increases, evaluating the dependability of critical IT systems becomes more important. One of the main challenges in software reliability engineering is the sensitivity of software systems to a changing usage. This is especially important for systems that are critical in the aftermath of a crisis and for which reliability is the most important aspect of dependabilit

Soil organic material (SOM) is usually enriched in (15)N in deeper soil layers. This has been explained by discrimination against the heavier isotope during decomposition or by the accumulation of (15)N-enriched microbial biomass versus plant biomass in older SOM. In particular, ectomycorrhizal (EM) fungi have been suggested to accumulate in old SOM since this group is among the most (15)N-enriche

The effect of antioxidant supplementation on biomarkers of oxidative stress was investigated in a 6-week intervention study in 60 overweight men. The supplement contained a combination of antioxidants aiming to correspond to the antioxidant content found in a diet rich in fruit and vegetables. Placebo, single or double dose of antioxidants was provided to the subjects. Metabolic variables, plasma

The performance of the ATLAS muon trigger system is evaluated with proton-proton collision data collected in 2012 at the Large Hadron Collider at a centre-of-mass energy of 8 TeV. It is primarily evaluated using events containing a pair of muons from the decay of [Formula: see text] bosons. The efficiency of the single-muon trigger is measured for muons with transverse momentum [Formula: see text]

Objective Two functional single nucleotide polymorphisms (SNP) in the PTPN22 gene (rs24746601 and rs33996649) have been associated with autoimmunity. The aim of this study was to investigate the role of the R263Q SNP for the first time and to re-evaluate the role of the R620W SNP in the genetic predisposition to systemic sclerosis (SSc) susceptibility and clinical phenotypes. Methods 3422 SSc pati

Popular Abstract in Swedish Vid förbränning av bränslen som innehåller kol, till exempel ved, olja och biobränslen, bildas sotpartiklar då det finns ett underskott av syre, så kallad ofullständig förbränning. Det är sotpartiklarna i brasan som ger dess gula sken. Dessa partiklar är små och består till största delen av oförbränt kol från bränslet. De små sotpartiklarna är hälsofarliga då de följer In the thesis work, two X-ray scattering techniques, small- and wide-angle X-ray scattering (SAXS and WAXS) were combined to study particle formation in-situ and non-intrusively in ethylene laboratory flames. Combining these two techniques enabled information concerning the size and concentration as well as the subnanometer structure of the nanoparticles within the 1–100 nm range there to be obtai

This thesis has two main objectives. The first is to analyse the potential of existing assessment tools and methods to incorporate the different dimensions of sustainability in an assessment. The second is to apply some of these tools in a case study in order to determine how forest sector can better contribute to sustainable development in Estonia. The first aim is addressed in a theoretical sect

Interstitial photodynamic therapy (IPDT) provides a promising means to treat large cancerous tumors and solid organs inside the human body. The treatment outcome is dependent on the distributions of light, photosensitizer, and tissue oxygenation. We present a scheme for reconstructing the spatial distribution of a fluorescent photosensitizer. The reconstruction is based on measurements performed i

Partial migration, in which a fraction of a population migrate and the rest remain resident, occurs in an extensive range of species and can have powerful ecological consequences. The question of what drives differences in individual migratory tendency is a contentious one. It has been shown that the timing of partial migration is based upon a trade-off between seasonal fluctuations in predation r

Background: Sickness absence has represented a growing public health problem in many Western countries over the last decade. In Sweden disorders of the musculoskeletal system cause approximately one third of all sick leave. The Social Insurance Agency (SIA) and the health care system are important actors in handling the sickness absence process. The objective was to study how patients with persona

We investigate the influence of the one-dimensional character of the phonon modes in a catalytically grown GaAs nanowire on the absorption spectrum of an embedded quantum dot, focusing on the on the contribution from the piezoelectric coupling. In general, the reduced dimensionally of the phonons leads to spectral side peaks and a zero-phonon line broadening due to the energetically lowest (acoust

Objectives: Cadmium (Cd) toxicity of the kidney varies between individuals despite similar exposure levels. In humans Cd is mainly bound to metallothioneins (MT), which scavenge its toxic effects. Here we analyzed whether polymorphisms in MT genes MTIA and MT2A influence Cd-related kidney damage. Methods: In a cross-sectional study N = 512 volunteers were selected from three areas in South-Eastern

Denna studie undersöker företags prisvariation mellan olika exportmarknader. Tidigare studier betonar kvalitetsskillnader som en viktig orsak till variationer i exportpriser. Vi utgår i stället från en alternativ förklaringsmodell som baseras på marknadssegmentering och studerar relationen mellan företagens prisvariation och deras markup. Vi använder detaljerad företags- och produktdata för en hel

Popular Abstract in Swedish Bröstcancer är den vanligaste cancerformen i världen bland kvinnor och bara i Sverige insjuknar varje år runt 7000 personer. Vi vet att omkring 10-15% av fallen troligen beror på ärftliga faktorer och det har under senare tid gjorts stora insatser för att klargöra exakt vilka arvsanlag som har betydelse för utveckling av sjukdomen. Under början av 90-talet identifieradeHereditary breast cancer constitutes a considerable fraction of the total number of breast cancer cases occurring each year. Up until recently very few breast cancer predisposing genes were known, but many new common polymorphisms contributing to increased cancer susceptibility are continuously being identified. This thesis has focused on familial breast cancer and identifying as well as investi

Complex health systems make it difficult for older persons (75+) with multi-morbidity to achieve continuity of care. Case management could be one way to address this difficulty. Currently, there is a need to extend the knowledge regarding case management as experienced by those utilising the services, namely older persons (75+) with multi-morbidity. The study aimed to explore older persons' (75+)

Purpose – This paper aims to discuss a new tool for requirements gathering in the Web 2.0 era. It seeks to investigate the features that this kind of tool should have in order to be as widely applicable and useful as possible. Further, it aims to explore the extent to which business requirements for enterprise resource planning (ERP) systems can be collected and discussed collaboratively in a worl
