Objective: Pain sensitization contributes to the complex osteoarthritis (OA) pain experience. The relationship between imaging features of hand OA and clinically assessed pain sensitization is largely unexplored. This study was undertaken to examine the association of structural and inflammatory features of hand OA with local pressure pain thresholds (PPTs) in the Nor-Hand study. Methods: The cros
Introduction: understanding motorcyclists’ on-the-road behaviour is critical for developing and evaluating interventions specifically targeting them. Risky on-the-road behaviours have historically been subdivided into errors and violations of the rules of road use. Police records could be used to record cyclists’ behaviours, however these documents do not necessarily capture all errors and violati
Gadolinium-148 is one of the radionuclides of most concern that will be produced in the tungsten target of the European Spallation Source (ESS), as a by-product of the spallation reaction used by the facility to produce neutrons. Since 148Gd a pure alpha emitter, it is both very radiotoxic and difficult to measure. With its half-life of 75 years, it will remain in the environment for a long time i
Legionellae are bacteria that naturally exist in freshwater environments, but have also been found in seawater and soils. Legionella can cause illnesses such as Legionnaires' disease or Pontiac Fever where the Legionnaires' disease is a severe variant of Pneumonia and Pontiac Fever is a milder influenza like variant.

Premise of research. Phenotypic traits that consistently mediate species’ responses to environmental variation (functional traits) provide a promising approach toward generalizing ecological and evolutionary patterns and thereby gaining insights into the processes generating them. In the plant functional ecology literature, most trait-based studies have focused on traits mediating either resource
Background and Aims: The mosses Homalothecium lutescens and H. sericeum are genetically, morphologically and ecologically differentiated; mixed populations sometimes occur. In sympatric populations, intermediate character states among gametophytes and sporophytes have been observed, suggesting hybridization and introgression in such populations. Methods: We determined genotypes using bi-allelic co
Wind power is seen by many observers as an important part of the transition to a sustainable energy system, since it does not contribute to the environmental problems connected with dominating energy forms such as fossil fuel, nuclear power and large-scale hydro power. At the same time wind power has some characteristics that makes it a special challenge for land use planning. In Sweden, where win
‘Virtual imagery as evidence in the contemporary context of the war on terror’ This paper explores the evidentiary role of virtual reproductions produced by the research project Forensic Architecture in the context of the contemporary battlefields of the war on terror. The digitization of war has created a networked landscape whose processes often remain invisible to the public. Although drone op
In many European universities, English is today used as a medium of instruction. One of the reasons is that it is believed that using English as a medium of instruction (EMI) can develop students’ subject-specific knowledge of English. This knowledge is seen as an asset in the workplace and often presented as providing a competitive advantage supporting professional success. The design of many edu
While calls to reduce air travel have emerged in many high-income countries, Nepal, with only one international airport, is still striving to improve its air connectivity. In 2015, the government resumed its 1995 plan to build a second international airport near Nijgadh, a town in the southern plains. The project has since come under scrutiny from conservationists after plans emerged for extensive
Popular Abstract in Swedish Genom århundradena har ingenjörskonsten och naturvetenskapen genomsyrats av en önskan att förstå och kontrollera den materia som omger oss. All materia, till exempel träd, byggnader och mobiltelefoner, består av olika slags atomer som är arrangerade i en mängd olika strukturer. Från människans första försök att tillverka redskap genom att manipulera flintstenar och metaThis thesis investigates different methods for treating strongly correlated systems, and discusses their respective strengths and weaknesses. Many of the results presented in this thesis come from comparing the different methods and approximations to exact results. Paper I: We studied the real-time dynamics of a trapped fermion gas, as it expands after removal of a trapping potential. Paper II: We
Urbaniseringen sker idag i snabb takt, men genom bebyggelseförtätning kan städernas utbredningshastighet avta. Behovet av att förtäta medför dock att urbana grönytor riskerar att få låg prioritet i stadsplaneringen om inte deras värden är tillräckligt tydliga. Syftet med denna studie är att tydliggöra värdet på de urbana grönytorna i Lunds kommun, samt att visa på potentialen att höja detta värde.Urbanization is a major driver of land-use change but the urban sprawl can be decreased by the densification of cities. On the other hand densification poses a threat to the urban green spaces; areas that have a high delivery of ecosystem services are essential to a high-quality living environment. The aim of this thesis is to illuminate the benefits of urban green space to raise their importance
Detailing how the cosmological environment surrounding a galaxy (large-scale structure) influences the local star-forming regions (small-scale structure) in the galaxy, and viceversa, remains an open question in the field of galaxy formation and evolution. Observations of massive star-forming galactic discs at extremely high redshifts have made this problem all the more pressing, putting current s
Dynamic global vegetation models are a common tool to assess the effect of climate and land use change on vegetation. Though most applications of dynamic global vegetation models use plant functional types, some also simulate species occurrences. While the current development aims to include more processes, e.g. the nitrogen cycle, the models still typically assume an ample seed supply allowing al
Introduction: Warfarin treatment with a high time in therapeutic range (TTR) is correlated to fewer complications. The TTR in Sweden is generally high but varies partly depending on local expertise and traditions. A dosing algorithm could minimize variations and increase treatment quality. Here we evaluate the performance of a computerized dosing algorithm. Materials and methods: 53.779 warfarin t
Conservation priority areas and programs are often established without consideration of future changes in species distributions. However, global change is expected to threaten the persistence of several species while offering opportunities for range expansion to others. In this study, building on previous work, we develop and implement an approach to classify bird species according to their degree
Aim: This paper describes the quality assurance (QA) work performed in the Swedish multicenter ARTSCAN (Accelerated RadioTherapy of Squamous cell CArcinomas in the head and Neck) trial to guarantee high quality in a multicenter study which involved modern radiotherapy such as 3DCRT or IMRT. Materials and methods: The study was closed in June 2006 with 750 randomised patients. Radiation therapy-rel
Popular Abstract in English Vernacular (local) architecture is in danger and about to disappear in several parts of the world. What we call native, traditional and handmade will disappear gradually and then the true meaning of vernacular vanishes. The present thesis shows that the disappearance of vernacular traditional skills creates an increasing threat to the existence of desert vernacular archDesert vernacular architecture has always been the product of a sustainable building cycle. People inherited the traditional way of building from their ancestors and the knowledge was transferred and developed from one generation to another. Inhabitants responded to their environment and climate through trial and error in a way that satisfied their needs and aspirations to create a developing buil
Popular Abstract in Swedish Grodyngels anpassning till livsmiljön - om betydelsen av, och samspelet mellan, arv och miljö Bakgrund Naturen är variabel och föränderlig. Inom en arts utbredningsområde kan miljöförhållandena variera rumsligt, och vad som är en lyckad strategi med avseende på t.ex. reproduktion eller predatorundvikande på en plats är inte nödvändigtvis den optimala strategin på en aAmphibian larvae are plastic in many traits. Can plasticity buffer population divergence, so that local adaptation is more common in non-plastic traits? I argue that this may be the case for adaptive plastic responses. Tadpoles of Rana arvalis are shown to alter their tail depth plastically as a response to predation risk; this is a truly adaptive response. Tail depths in the field (population and
Popular Abstract in Swedish Kvantprickar är objekt där elektroner är instängda i en mycket liten volym (av storleksordningen 100 nanometer i varje riktning). I den här avhandlingen har vi studerat kvantprickar definierade i nanotrådar av halvledarmaterial. Nanotrådarna kan vara flera mikrometer långa men samtidigt mycket tunna (mindre än 100 nanometer eller 0,1 mikrometer). Vi har skapat kvantpriThis thesis focuses on electrical transport in semiconductor InAs nanowires grown by chemical beam epitaxy. Initially, transport length scales of homogeneous InAs n-type nanowires are characterized by low-temperature magnetoconductance measurements. The measurements show phase-coherent conductivity corrections. By fitting the data, we find the nanowire mean-free path to be 50 nm and the phase-cohe
