Background. Sunlight exposure and fair skin are major determinants of human vitamin D production, but they are also risk factors for cutaneous malignant melanoma (MM). There is epidemiological evidence that all-cause mortality is related to low vitamin D levels. Methods. We assessed the avoidance of sun exposure as a risk factor for all-cause mortality for 29 518 Swedish women in a prospective 20-
Background: Familial clustering of incident prostate cancer and some cancers at other discordant sites has been reported. Less is known about familial clustering of fatal prostate cancer with any fatal discordant cancers. Estimates on familial aggregation based on mortality are free from bias of overdiagnosis. Patients and methods: We used the nationwide Swedish Family-Cancer Database to calculate
Bombus terrestris is one of the most commonly used insect models to investigate visually guided behavior and spatial vision in particular. Two fundamental measures of spatial vision are spatial resolution and contrast sensitivity. In this study, we report the threshold of spatial resolution in B. terrestris and characterize the contrast sensitivity function of the bumblebee visual system for a dua
The purpose of this study was to develop techniques to quantify the propagation pattern of the electrical activation during atrial fibrillation (AF) along a one-dimensional catheter. Taking intra-atrial signal organization aspects into account, the atrial activations are detected and combined into wavefronts. Parameters describing wavefront consistency and activation order along the catheter are d
Tramways are a sustainable and accessible mode for public transport. They promote urban development and contribute to a more attractive city. Light rail, but also public transport as a whole, is an important part of society as it is accessible to everyone and reduces the amount of cars needed. The two tramlines in Norrköping account for two thirds of public transport travel in the city. The purpos
The purpose of this thesis is to find out to what extent Sweden’s new liberal approach towards labour migration is a case of Europeanization. The intention is also to illustrate the gradual Europeanization in the area of labour migration and discuss the new paradigm shift in favour of labour migration. Managed migration is the new ‘catch word’ where the focus primarily is on skilled labour. A top-
The aim of this study was to gain knowledge about leadership style and its relation to coworker's wellbeing. Of special interest was to find the best predictor variable of wellbeing. A further aim was to study differences between males and females in organizational commitment and wellbeing. A questionnaire was distributed to 100 employees in Telia, a Swedish telecom company. 62 questionnaires
In this thesis, the Wideband Sparse Exponential Mode Analysis (WSEMA) estimator is introduced. It combines two recently developed techniques, the wideband dictionary and the Sparse Exponential Mode Analysis (SEMA) to make for an efficient estimator. WSEMA estimates the parameters of decaying sinusoids, without a priori-information about the number of modes present in the signal. WSEMA works with a
From a reputation of an industrial and trading city, Aalborg has changed into a contemporary university city, with a strong development of creative clusters in knowledge-based industries. Nowadays the Vækstaksen, an urban growth axis set by the municipality, has become the driving force in the city’s development to avoid further sprawl. A great part of East Aalborg belongs to this axis and is curr
Syfte: Huvudsyftet med studien var att undersöka den phonicsbaserade lärappen GraphoLearns effekter på avkodningsförmågan hos svensktalande barn i tidig läsutveckling. Sekundärt var syftet att undersöka huruvida träning med GraphoLearn kan påverka hjärnstruktur. Studien kan betraktas som en pilotstudie för ett större pågående projekt. Metod: Fjorton deltagare i åldrarna 6 till 7 år inkluderades. S
Uppsatsen handlar om den rättsliga regleringen kring den småskaliga vat-tenkraften i Sverige. Uppsatsen beskriver därför till stor del det svenska re-gelverket kring småskalig vattenkraft, samt miljöskyddet för miljön och ekologin i anslutning till den småskaliga vattenkraften. På EU-rättens om-råde finns ett antal rättsakter som på ett mer eller mindre omfattande sätt berör den småskaliga vattenk
Thailand is facing with various extreme climate events from flood to drought. As a result of climate change, these events tend to increase in frequency and intensity. The existing water infrastructures and management is showing sign of fragility and incapable of dealing with these challenges. To increase adaptive capacity and tackle current water resource challenges, water management agencies in T
Incorporating a multi-year grass ley into an arable crop rotation can increase soil organic carbon stocks, reduce carbon emissions and provide feedstock for biogas. This thesis set out to study how a policy promoting agricultural biomass for biogas impacts GHG emissions and carbon sequestration on a regional level over a temporal scale of 20 years. This was done in the specific case of policy prom
Background: Primary healthcare providers are increasingly challenged in supporting patients with psychosocial needs. Arts on Prescription (AoP) has been shown to improve primary healthcare patients’ mental health wellbeing. The aim of the current study is to understand the psychosocial effect of participating in an Arts on Prescription programme. Methods: A total of 112 primary healthcare patients
Background: Lung injury in COVID-19 is characterized by neutrophil invasion and the release of neutrophil extracellular traps (NETs). An aberrant NET formation may induce local inflammation and increase sputum viscosity. Inhalation of DNase I (dornase alfa) is a treatment option that degrades NETs in the airways. Previous case series have indicated positive clinical effects of inhaled dornase alfa
α-Synuclein is a synaptic protein that accumulates primarily in synucleinopathies and secondarily in certain lysosomal storage disorders. However, its physiological roles in health and disease are not fully understood. In part, this has been hampered by the inability to visualize α-synuclein and its cellular localization, due to the lack of specific antibodies and faithful reporters. Here, we used
