The purpose of the study was to evaluate how breathing motion during tomotherapy (Accuray, CA, USA) treatment affects the absorbed dose distribution. The experiments were carried out using gel dosimetry and a motion device simulating respiratory-like motion (HexaMotion, ScandiDos, Uppsala, Sweden). Normoxic polyacrylamide gels (nPAG) were irradiated, both during respiratory-like motion and in a st
The paper aims to elucidate in better detail than before the dispute about whether or not dispositional monism—the view that all basic properties are pure powers—entails a vicious infinite regress. Particular focus is on Alexander Bird’s and George Molnar’s attempts to show that the arguments professing to demonstrate a vicious regress are inconclusive because they presuppose what they aim to prov
Disperse dyes are well-known contact sensitizers. However, they are not included in the majority of commercially available baseline patch test series.
The International Association of Diabetes and Pregnancy Study Groups (IADPSG) has suggested new diagnostic criteria for gestational diabetes mellitus. Many centers in Europe still use the World Health Organization (WHO) criteria. In southern Sweden we use the 2-h threshold of the European Association for the Study of Diabetes criteria based on universal screening with a 75-g oral glucose tolerance
The main objective is to determine the overall prevalence of anemia in inflammatory bowel diseases (IBD) in Europe.
We investigate whether Swedish Environmental Protection Agency (EPA) administrator recommendations regarding improvements in environmental quality differ from citizen preferences. This is done by conducting identical choice experiments on both citizens and administrators at the EPA. The administrators were asked to choose the alternatives they would recommend as a policy, while the citizens were a
Studies have shown terminal QRS distortion and resultant QRS prolongation during ischemia to be a sign of low cardiac protection and thus a faster rate of myocardial cell death. A recent study introduced a single lead method to quantify the severity of ischemia by estimating QRS prolongation. This paper introduces a 12-lead method that, in contrast to the previous method, does not require access t
Previous studies of prostate cancer (PCa) risk and anthropometrics (ie, body measurements) were based on single measurements or obtained over limited time spans.
Exposure to inorganic arsenic increases the risk of basal cell carcinoma (BCC). Arsenic metabolism is a susceptibility factor for arsenic toxicity, and specific haplotypes in arsenic (+3 oxidation state) methyltransferase (AS3MT) have been associated with increased urinary fractions of the most toxic arsenic metabolite, methylarsonic acid (MMA). The aim of this study is to elucidate the associatio
The 12-item Short-Form Health Survey (SF-12) is an abbreviated version of the SF-36, one of the most widely used patient-reported health outcome rating scales. Similar to the SF-36, it yields summary scores of physical and mental health (PCS and MCS, respectively). However, SF-36 derived PCS and MCS scores have not been found valid in neurological disorders such as Parkinson's disease (PD). Here w
ABSTRACT. Preterm newborn infants have a high morbidity rate. The most frequently affected organs where free gas is involved are the lungs and intestines. In respiratory distress syndrome, both hyperexpanded and atelectatic (collapsed) areas occur, and in necrotizing enterocolitis, intramural gas may appear in the intestine. Today, these conditions are diagnosed with x-ray radiography. A bed-side,
For an extension $A/B$ of neither necessarily associative nor necessarily unital rings, we investigate the connection between simplicity of $A$ with a property that we call $A$-simplicity of $B$. By this we mean that there is no non-trivial ideal $I$ of $B$ being $A$-invariant, that is satisfying $AI \subseteq IA$. We show that $A$-simplicity of $B$ is a necessary condition for simplicity of $A$ f
Scholarly discourses on energy security have developed in response to initially separate policy agendas such as supply of fuels for armies and transportation, uninterrupted provision of electricity, and ensuring market and investment effectiveness. As a result three distinct perspectives on energy security have emerged: the `sovereignty' perspective with its roots in political science; the `robust
Hidden Markov models are often applied in quantitative finance to capture the stylised facts of financial returns. They are usually discrete-time models and the number of states rarely exceeds two because of the quadratic increase in the number of parameters with the number of states. This paper presents an extension to continuous time where it is possible to increase the number of states with a l
The Model of Emissions of Gases and Aerosols from Nature (MEGANv2.1) together with the Modern-Era Retrospective Analysis for Research and Applications (MERRA) meteorological fields were used to create a global emission data set of biogenic volatile organic compounds (BVOC) available on a monthly basis for the time period of 1980-2010. This data set, developed under the Monitoring Atmospheric Compo
The presence of mouth alcohol (MA) during alcohol breath test for law enforcement is the most common cause of falsely high breath alcohol concentrations (BrAC). A fast and reliable test for detection of MA roadside at the scene of the act would facilitate the police efforts for proper prosecution. A tentative technique to use orally exhaled water vapour as a reference gas to position the origin of
Det övergripande syftet med artikeln är att med hjälp av en teoretisk utgångspunkt beskriva, analysera och försöka förstå varför biståndshandläggarna i sin dagliga yrkesutövning normaliserar en restriktiv hållning när äldre personer överväger en flytt till ett särskilt boende. Medan tidigare forskning i stor utsträckning har uppmärksammat på vilket sätt biståndshandläggarna tillämpar en restriktivBy applying a theoretical point of departure, the overarching aim of this article is to describe, analyze, and try to understand why care managers in their everyday occupational practice normalize the restrictive approach when older people consider relocation to a residential home. While earlier research to a large extent has drawn attention to how the care managers carry out the restrictive appro
The aim of the study was to investigate workplace incivility as a social process, examining its components and relationships to both instigated incivility and negative outcomes in the form of well-being, job satisfaction, turnover intentions, and sleeping problems. The different components of incivility that were examined were experienced and witnessed incivility from coworkers as well as supervis
This paper examines the formation and expansion of a new organizational field in experimental science: synchrotron radiation laboratories. These labs were once peripheral servants of some specialisms of solid-state physics, but over the 40 years studied they have grown into a worldwide generic resource for tens of thousands of users in a broad spectrum of disciplines. The paper uses insights prima
