Single top quark production via four-fermion contact interactions associated to flavour-changing neutral currents was searched for in data taken by the DELPHI detector at LEP2. The data were accumulated at centre-of-mass energies ranging from 189 to 209 GeV, with an integrated luminosity of 598.1 pb(-1). No evidence for a signal was found. Limits on the energy scale Lambda, were set for scalar-, v
A cohort of 1,220 farmers, 1,130 nonfarming rural men, and 1,087 urban referents from Sweden were monitored for 12 years. Farmers had lower mortality than urban referents for all causes of death (hazard ratio [HR] = 0.51; 95% confidence interval [CI], 0.37-0.71), cancer (HR = 0.44; 95% CI, 0.24-0.78) and cardiovascular diseases (HR = 0.60; 95% CI, 0.36-0.99). Nonfarming rural men had lower mortali
Objective. Patients with hepatitis C have been shown to have impaired health-related quality of life (HRQoL). The aim of this study was to determine HRQoL in patients in different stages of hepatitis C virus (HCV) and to compare HRQoL in HCV cirrhosis with non-HCV-induced cirrhosis. Material and methods. Out of 489 consecutive patients who fulfilled the inclusion criteria, 472 (96%) agreed to part
Robust and reliable formulas for predicting bed load and suspended load were developed for application in the nearshore zone where waves and currents may transport sediment separately or in combination. Also, a routine was included to determine the sediment transport in the swash zone, both in the longshore and cross-shore directions. An important objective of the development was to arrive at gene
Popular Abstract in Swedish I denna avhandling undersöks argumentationsstrategier för att legitimera eller delegitimera en sak eller person i Sveriges tidiga politiska debatt i pamfletter. Det empiriska syftet med är att undersöka det politiska språket i den framväxande politiska offentligheten, med fokus på år 1769 och 1809-1810. Det teoretiska och metodologiska syftet är att diskutera vilket slaThis thesis discusses argumentative strategies for legitimation and delegitimation in political pamphlets published in 1769 and in 1809–1810, each period representing the onset of democracy and freedom of the press. The aim of the study is twofold. The empirical aim is to examine the political language in the early political debate in pamphlets, with a focus on how the discursive strategies of leg
This article examines ways of constructing research questions from existing literature, which are likely to promote the development of interesting and influential theories. We review 52 articles in organization studies and develop a typology of how researchers construct their research questions from existing literature. The most common way across paradigmatic camps is to spot various 'gaps' in the
Background: Epidemiologic evidence of an association between fish intake and type 2 diabetes (T2D) is inconsistent and unresolved. Objective: The objective was to examine the association between total and type of fish intake and T2D in 8 European countries. Design: This was a case-cohort study, nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) study, with 3.99 m
Abstract in Undetermined De arkeologiska, medicinhistoriska och etnografiska källorna visar att trepanationer är ett univer- sellt fenomen, men också intimt kulturspecifikt i sitt syfte och i sin handling. Denna operationskonst visar att personer klarat de påfrestningar ett sådant ingrepp medfört, och att kunskapen om hälsa och ohälsa inte varit främmande i de mest skilda kulturella sammanhang. De
A fully instrumented slice of the ATLAS detector was exposed to test beams from the SPS (Super Proton Synchrotron) at CERN in 2004. In this paper, the results of the measurements of the response of the barrel calorimeter to hadrons with energies in the range 20-350 GeV and beam impact points and angles corresponding to pseudo-rapidity values in the range 0.2-0.65 are reported. The results are comp
This article examines how ordinary Russian and Ukrainian citizens experience and relate to extensive and pervasive corruption (high- level, everyday, political) in everyday discussions and demands – in relation to authorities, politicians, civil servants, and fellow citizens. Anonymous interviews conducted in Ukraine and Kaliningrad oblast from 2009 to 2014 show differences in anti-corruption dema
Uncultivated field margins are one of the most frequent non-crop habitat types in contemporary, highintensity agricultural landscapes and may therefore be important for the persistence of many farmland species. Managing field margins in a way that preserves, and preferably enhances, their value for biodiversity is therefore important. In the present study, we evaluate how the flora of uncultivated
Natural disturbances play a key role in ecosystem dynamics and are important factors for sustainable forest ecosystem management. Quantitative models are frequently employed to tackle the complexities associated with disturbance processes. Here we review the wide variety of approaches to modelling natural disturbances in forest ecosystems, addressing the full spectrum of disturbance modelling from
The stability of beams of laser wakefield accelerated electrons in dielectric capillary tubes is experimentally investigated. These beams are found to be more stable in charge and pointing than the corresponding beams of electrons accelerated in a gas jet. Electron beams with an average charge of 43 pC and a standard deviation of 14% are generated. The fluctuations in charge are partly correlated
Identification and isolation of cardiomyocytes from the heart, embryonic stem cells, or induced pluripotent stem cells is a challenging task and will require specific isolation techniques. Less than 30% of the cells within the murine heart are cardiomyocytes and, what is more, there are multiple sub-populations of cardiomyocytes like atrial, ventricular and conduction system cardiomyocytes. In Pap
Lentic water bodies (lakes and reservoirs) offer favorable conditions for silica (SiO2) burial in sediments. Recent global estimates suggest that (1) lentic SiO2 trapping is a globally important SiO2 flux, and (2) through reservoir construction, humans have dramatically altered river dissolved SiO2 (DSi) transport and coastal DSi delivery. However, regional to global scale patterns and controls of
We examined background information and course of labour from a cohort of 2,810 low-risk nulliparas to identify possible lifestyle and anthropometrical risk indicators for dystocia. Criteria for dystocia: cervical dilatation <2 cm over 4 h during labour's active phase, or no descent during 2 h (3 h with epidural) in the descending phase, or no progress for 1 h during the expulsive phase. After adju
