The Siljan impact structure is the largest known impact structure in Europe, the result of a Late Devonian meteorite impact (380.9 +/- 4.6 Ma). It is outlined mainly by a ring of lakes and Palaeozoic sedimentary rocks of Ordovician to Devonian age. The Palaeozoic successions are generally poorly exposed, but often well preserved with clear stratigraphy. At some locations they are strongly tectonis

Background: The widening socioeconomic gap in smoking during pregnancy remains a challenge to the Swedish antenatal care services. However, the influence of cultural factors in explaining the socioeconomic differences in smoking during pregnancy is not clear among the immigrant women. The aim of this study was to investigate whether the development of smoking prevalence among pregnant immigrant wo

Popular Abstract in Swedish Sjukdomsuppfattningar. Värderingar och attityder hos patienter och medicine studerande. Utvecklingen av den biomedicinska kunskapen och de demografiska förändringarna under 1900-talet har inneburit en ökning av såväl behov av som efterfrågan på hälso- och sjukvård. Illabefinnande utan påvisbara sjukdomstecken och rädsla för sjukdom ligger ofta bakom vårdsökande. OfficieDuring the 20th century, the development of biomedical knowledge and the demographical changes have increased the needs and demands for health care in industrialised countries. Illness without evidence of disease and fear of disease are often the reasons for seeking medical care. Primary care is the official foundation of the Swedish health care system but priorities are vague and frequently chang

The present thesis investigates the usage of cultural heritage resources on the web. In recent years cultural heritage objects has been digitalized and made available on the web for the general public to use. The thesis addresses to what extent the digitalized material is used, and how findable it is on the web. On the web resources needs to be findable in order to be visited and used. The study i

Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes. The Ca2+ gradients are used by the cell to transmit information in a variety of physiol

Popular Abstract in Swedish Denna avhandling syftar till att belysa vilket professionskunnande som blivande lärare ges möjlighet att utveckla under sin högskoleförlagda utbildning och hur detta professionskunnande kan karaktäriseras. Detta belyses genom ett antal forskningsfrågor: Vilka olika undervisningspraktiker konstituerar den högskoleförlagda lärarutbildningen? På vilket sätt upprättas dessaThe starting point for this dissertation was the reform of the school system in Sweden with consequences for teachers´ work and new demands on their professional knowledge. This thesis aims to illuminate the issue of what professional knowledge student teachers are offered during their time in the university, and how this professional knowledge can be characterised. This is carried out with respec

It has been generally accepted that residual cartilage and subchondral bone has to be removed in order to get bony fusion in arthrodeses. In 1998 we reported successful fusion of 11 rheumatoid ankles, all treated with percutaneous fixation only. In at least one of these ankle joints there was cartilage left. More than 25 rheumatoid patients with functional alignment in the ankle joint have subsequ

Popular Abstract in Swedish Det finns ett starkt samband mellan en förenings struktur och dess egenskaper. En detaljerad tredimensionell bild av en förenings struktur på molekylnivå är därför grundläggande information för att förstå dess reaktivitet, stabilitet och fysikaliska egenskaper. Röntgenkristallografi är ett utmärkt redskap för att ta reda på ett ämnes struktur i en kristall. En kristallsThis thesis focuses on i) the effect of packing on the molecular geometry ii) packing arrangements of neutral Pd(II) and Pt(II) complexes iii) the trans influence in Pt(II) complexes iv) the differences in bonding in corresponding Pd(II) and Pt(II) complexes and v) the geometry of Pd(II) complexes with potential catalytic properties. Detailed three-dimensional structural information at the atomic

Popular Abstract in Swedish När vi tänker på skönlitteraturen får den gärna en drömmande klang som för tankarna till främmande platser långt borta från vardagen. Samtidigt kan skönlitteraturen måla upp slående bilder av världen och övertygande sätta in politiska och kulturella frågor i ett större meningsfullt sammanhang. Ingenstans blir detta tydligare än i Brands skönlitteratur. I det ungsocialisThis study delves into the relationship between fiction and politics, aesthetic and ethical messages conveyed by the fictions of Brand (Fire), the journal of the Young Socialist Association, founded as the Social Democratic Labour Party’s first youth association. The literary and aesthetic arena allowed many different kinds of ideas and thoughts to flourish, making Brand an important cultural pape

Adsorption of cationic polyelectrolytes onto polystyrene latices was studied as function of polymer chemical composition and molecular weight, polymer and surface charge density and ionic strength. The ratio between polymer charges and surface charges was close to one when distances between polymer and surface charges were equal. Overcompensation of the surface charge was obtained at higher polyme

The role of oxidants in viral diseases is fairly complex because it includes metabolic regulation both of host metabolism and viral replication. However, a role for reactive oxygen species (ROS) and reactive nitrogen species (RNS) as mediators of virus-induced lung damage is supported by studies and antioxidants can thus be expected to act at many different levels. The aim of the present pilot stu

Trends in Hodgkin lymphoma (HL) survival among patients treated outside of clinical trials provide real-world benchmark estimates of prognosis and help identify patient subgroups for targeted trials. In a Swedish population-based cohort of 1947 HL patients diagnosed 1992-2009 at ages 18-59 years, we estimated relative survival (RS), cure proportions (CP) and median survival times using flexible pa

Force sensing provides robots the capability to accomplish tasks where physical interaction with the environment is required, such as assembly. Small position uncertainties can then be corrected for by sensing the contact forces. This thesis considers the problem of force-controlled assembly, including how tasks can be specified in a simple and intuitive way and how robust task execution under unc

Background: Overweight is reported as a side effect of SDR. The aims were to study the development of weight, height and body mass index (BMI) during five years after SDR. Methods: This prospective, longitudinal and practice-based study included all 56 children with CP spastic diplegia undergoing SDR from the start in March 1993 to April 2003 in our hospital. The preoperative Gross Motor Function

Background: Sweden is a high endemic region for multiple sclerosis (MS), a neurologic disorder characterized by repeated inflammatory episodes affecting the CNS. The disease has its peak age of onset at approximately 30 years and affects women twice as often as men. The young age of onset makes MS one of the major causes of reduced capacity to work due to neurologic disease in Western society. Nat

Design: This was a retrospective cohort study. Methods: A total of 525 consecutive patients (73% elective) with AAA underwent EVAR at two vascular centres from 2008 t

Aim The northern limits of temperate broadleaved species in Fennoscanndia are controlled by their requirements for summer warmth for successful regeneration and growth as well as by the detrimental effects of winter cold on plant tissue. However, occurrences of meteorological conditions with detrimental effects on individual species are rare events rather than a reflection of average conditions. W

PURPOSE: To investigate whether separate physical tests of the lower extremities, that assess movement speed and postural control, were associated with cognitive impairment in older community-dwelling subjects. SUBJECTS AND METHODS: In this population-based, cross-sectional, cohort study, the following items were assessed: walking speed, walking 2 × 15 m, Timed Up and Go (TUG) at self-selected an

Introduction: The aim of this study was to investigate the role of hand bone mineral density (BMD) loss analyzed with digital X-ray radiogrammetry (DXR) in early rheumatoid arthritis (RA) as a predictor for progression of joint damage. Methods: In 379 patients with early RA, baseline and one-year hand BMD was measured with DXR and the hand bone loss (HBL) was analyzed using the smallest detectable
