Nordic countries have experienced multiple glaciations and intervening interglacials during the last ca. 2.5-3 million years. Although evidence from Greenland and Iceland shows that ice sheets started to expand some time before 3 Ma, little is known about the glaciations and intervening interglacials older than the last Glacial Maximum due to repeated phases of glacial erosion and reworking. The e
Changes in sulphur and nitrogen pollution in Swedish forests have been assessed in relation to European emission reductions, based on measurements in the Swedish Throughfall Monitoring Network. Measurements were analysed over 20 years with a focus on the 12-year period 1996 to 2008. Air concentrations of SO2 and NO2, have decreased. The SO4-deposition has decreased in parallel with the European em
Background: Proteolytic Clostridium botulinum is the causative agent of botulism, a severe neuroparalytic illness. Given the severity of botulism, surprisingly little is known of the population structure, biology, phylogeny or evolution of C. botulinum. The recent determination of the genome sequence of C. botulinum has allowed comparative genomic indexing using a DNA microarray. Results: Whole ge
Objective. To investigate the type of urinary diversion performed after cystectomy in patients with muscle-invasive bladder cancer in Sweden, using data from a population-based national register. Material and methods. Since 1997, the Swedish Bladder Cancer Register has included more than 90% of all patients with newly diagnosed bladder cancer. The different types of urinary diversion performed in
The 1990s was the era of human rights awareness, democratic transitions, and growing involvement of international organizations and the nongovernmental sector in human rights education (HRE). The UN Decade for HRE from 1995-2004 was not only born out of the initiatives and pressures of nongovernmental organizations (NGOs) but it also actively triggered many new private initiatives and commitments
Background: Previous studies of the association between gestational age or birth weight and allergic rhinitis in later life have had various limitations, including the inability to estimate risk among subjects born extremely preterm or to examine specific contributions of gestational age and fetal growth. Objective: We sought to determine whether gestational age at birth independent of fetal growt
Autoignition of hydrogen in air was studied in a turbulent flow reactor using OH*-chemiluminescence. High-speed imaging was used to visualise the formation of auto-ignition kernels in the flow, and to analyse the conditions under which temporary stabilisation of the flame kernels occurred. The experiments were carried out at temperatures of 800-850 K, pressures of 0.8-1.2 MPa and an equivalence ra
Birds can save distance and time on their migratory journeys by following great circles rather than rhumblines, but great-circle routes require more complex orientation with changing courses. Flight directions at different places along the route and in relation to the destination can be used to test whether birds migrate along great circles or rhumblines. Such data have indicated great-circle migr
Background: Public transport is low cost, allows for independence, and facilitates engagement and participation for non-drivers. However, the viewpoints of individuals with cognitive disabilities are rarely considered. In Australia, the prevalence of Autism Spectrum Disorders (ASD) is approximately 1% and increasing. Many individuals with ASD do not possess a driver's licence, indicating that acce
Background: Long-term exposure to air pollution is a hypothesized risk factor for ischemic stroke. In a large case-control study with a complete study base, we investigated whether hospital admissions for ischemic stroke were associated with residential concentrations of outdoor NOx, as a proxy for exposure to air pollution, in the region of Scania, Southern Sweden. Methods: We used a two-phase ca
In electromyographic (EMG) and functional magnetic resonance imaging (fMRI) studies, muscle and brain activity was compared during low levels of tooth clenching using a novel biting device to control bite force. A total of 21 healthy subjects performed motor tasks, comprising tooth clenching at 5, 10 and 20N. During all measurements, subjects kept the novel bite device between the anterior teeth d
Context:Patients with treated adrenal insufficiency (AI) have increased morbidity and mortality rate. Our goal was to improve outcome by developing a once-daily (OD) oral hydrocortisone dual-release tablet with a more physiological exposure-time cortisol profile.Objective:The aim was to compare pharmacokinetics and metabolic outcome between OD and the same daily dose of thrice-daily (TID) dose of
Natural resource management requires approaches to understand and handle sources of uncertainty in future responses of complex systems to human activities. Here we present one such approach, the "biological ensemble modeling approach,'' using the Eastern Baltic cod (Gadus morhua callarias) as an example. The core of the approach is to expose an ensemble of models with different ecological assumpti
Physiological and psychosocial factors might contribute to differences in weight loss, eating behaviour and health-related quality of life (HRQoL) after bariatric surgery. The aim of this study was to investigate how perceived control over eating changes after bariatric surgery and whether it affects outcome in super-obese patients. In a retrospective analysis of a prospective study (n = 60), 49 p
The stem of Agave tequilana Weber is used to obtain fructans. Reports on the potential prebiotic activity of agave fructans as ingredients are scarce. The aim of this study was to evaluate the indigestible fraction (IF) content and the short chain fatty acid production (SCFA) from in vitro fermentation of: Native-agavefructans (NAF), agave-dietary-fiber (ADF), high-performance-fructans (HPF), both
Five different low-Mach large eddy simulations are compared to the turbulent stratified flame experiments conducted at the Technical University of Darmstadt (TUD). The simulations were contributed by TUD, the Institute for Combustion Technology (ITV) at Aachen, Lund University (LUND), the EM2C laboratory at Ecole Centrale Paris, and the University of Duisburg-Essen (UDE). Combustion is modeled by
OBJECTIVE: We synthesized the main findings from an international epidemiologic study on the impact of biopersistent organic pollutants (POPs) on human reproductive function. DATA SOURCES AND EXTRACTION: We used a database with interview and biological data from 2,269 women and their spouses, and 18 published core papers. DATA SYNTHESIS: The study did not provide direct evidence of hormone-like ac
Popular Abstract in Swedish Studien handlar om en konflikt kring en muslimsk friskola i Jönköping. Utifrån fältarbete på den muslimska friskolan och en ordinarie grundskola i kommunen, femton intervjuer och ett omfattande tidningsmaterial har jag problematiserat relationen mellan olika grupper i samhället och vem som har tolkningsföreträde i frågor om skola, fostran och värderingar. De muslimska fThe study is about a conflict concerning a Muslim Independent School in Jönköping. Based on fieldwork carried out on the Muslim Independent School and one of the local authority´s comprehensive schools - which included fifteen interviews and a comprehensive collection of newspaper articles and reports - I have problemised the relationship between the different groups in the local community and who
This thesis concerns a highly efficient nanoparticle-based capillary electrochromatography separation technique and its coupling with mass spectrometric detection. From chromatographic theory, it is well known that the separation efficiency increases with decreasing particle size. However, as the particle size decreases, the pressure required to push a liquid through the column also increases. Thi
Context: SHBG regulates free sex steroid levels, which in turn regulate skeletal homeostasis. Twin studies have demonstrated that genetic factors largely account for interindividual variation in SHBG levels. Glucuronidated androgen metabolites have been proposed as markers of androgenic activity. Objective: Our objective was to investigate whether polymorphisms in the SHBG gene promoter [(TAAAA)(n
