In hybrid zones populations that are otherwise allopatric meet and produce hybrids. One of the most well-known hybrid zones occurs throughout much of Europe between the hooded and carrion crows. Even though these species (or subspecies) of crows look very different, genetic differentiation is weak, and introgression seems to be common. In a spatial simulation that was based on empirically estimate
Popular Abstract in Swedish Hur man värderar resultat av kirurgisk behandling av ländryggens degenerativa åkommor är ett stort, komplext och delvis kontroversiellt ämne. Denna avhandling studerar resultatvärdering med olika metoder och instrument, huvudsakligen baserat på resultat från det nationella svenska ländryggskirurgiregistret. Arbete I. Inventering av befintliga instrument i litteraturen No consensus regarding outcomes assessment in spine patients exists. Health-Related Quality of Life (HRQoL) questionnaires are increasingly used. The objective of this thesis was the evaluation of HRQoL measures before and after lumbar spine surgery, and their relation to other evaluation parameters as well as relevance of differences. The patients included were operated on for lumbar spine disor
The author of this thesis wishes to contribute to transitions towards more sustainable energy systems in Argentina. In order to do so, two objectives are established. The first one refers to increasing the understanding of the transitions taken place at the local level within energy supply systems in Sweden. The second objective is to increase the understanding of the conditions that need to be in
I takt med att världens befolkning ökar och allt fler väljer att bosätta sig inne i staden ökar behovet av att hitta smarta och hållbara sätt att förtäta. En stad har sina begränsningar och därför har det genomgående i projektet varit viktigt att undersöka hur vi kan töja på stadens gränser och tillföra nya värden utan att tumma på befintliga kvaliteter. Att förtäta en stad är en möjlighet att höjAs the world population increases and more people choose to settle in the city the need to find smart and sustainable solutions to densify increases. A city has limitations and therefore it has been important to look at how we can stretch the city´s borders and adding new values without compromising the existing qualities. To densify a city is an opportunity to improve existing urban spaces and in
The field of Cognitive Psychology has discovered a large number of automatic and systematic errors of judgement that humans make. These are called cognitive biases and cause irrational behavior in diverse contexts. Prior research has found that cognitive biases can cause irrational behavior in companies. For example company functions, such as planning, have been found to suffer from systematic err
INTRODUCTION: Snakebite accidents are an important health problem in rural areas of tropical countries worldwide, including Costa Rica, where most bites are caused by the pit-viper Bothrops asper. The treatment of these potentially fatal accidents is based on the timely administration of specific antivenom. In many regions of the world, insufficient health care systems and lack of antivenom in rem
Objective: To study transitions from and to chronic widespread pain (CWP) over 7 years in patients with rheumatoid arthritis (RA). Method: Two postal questionnaires were sent to patients included in the BARFOT (Better Anti-Rheumatic Pharmacotherapy) study, the first in 2010 and the second in 2017. The questionnaires assessed pain, number of tender and swollen joints, functional disability, health-
Aim. This study describes the meanings of generalist registered nurses' experiences of caring for palliative care patients on general wards in hospitals. Background. Earlier research shows that work with patients in palliative care is demanding. More research concerning palliative care is undertaken in oncological care, in hospice and in home-care settings than in general wards. It is therefore im
Study Design: A nonblinded randomized controlled trial. Introduction: Occupation-based interventions are superior to physical exercise–based interventions in patients with activity limitations. However, only a few studies have examined the effect in patients with hand-related disorders. Patients recover heterogeneously, which could be due to personal factors, such as sense of coherence (SOC). Purp
Popular Abstract in Swedish Skogen utgör en viktig del av kolbalansen mellan mark och luft och har en potential att reducera koncentrationen av koldioxid i atmosfären. Mängden bladyta i en skog ger en indikation på skogens förmåga att binda koldioxid till marken. Den här avhandlingen utforskar möjligheterna att erhålla information om skogars mängd av bladyta med hjälp av den information som registThis thesis deals with methods of obtaining the leaf area index (LAI) from remotely sensed satellite data. Initially, in situ estimation methods were investigated, since the accuracy of the remotely sensed estimates is dependent on the quality of these estimates. The results of the present studies indicate that some methods commonly used as a reference for more complicated methods could result in
Knowledge resistance can be defined as the state where we are “almost immune to evidence, or experiences of others” (Klintman 2022:323). The phenomenon, often described using related terms, remains highly relevant to understanding the challenges and opportunities of agreeing on the existence, severity, causes and solutions to environmental problems. The concept of knowledge resistance is related t
With the explosive growth of communication traffic, increasing the modulation bandwidth of semiconductor lasers has attracted significant attention. However, after rapid progress is achieved, further increasing the modulation bandwidth of semiconductor lasers is hampered by the slow charge-carrier dynamics. Here, a room temperature, single-mode perovskite nanolaser with sub-picosecond pulses, enab
Background and objective: The treatment landscape of metastatic prostate cancer (mPCa) has evolved significantly over the past two decades. Despite this, the optimal therapy for patients with mPCa has not been determined. This systematic review identifies available predictive models that assess mPCa patients’ response to treatment. Methods: We critically reviewed MEDLINE and CENTRAL in December 20
Treating severe dermal disruptions often presents significant challenges. Recent advancements have explored biological cell sprays as a promising treatment, but their success hinges on efficient cell delivery and complete wound coverage. This requires a good spray distribution with a small droplet size, high particle number, and ample surface coverage. The type of nozzle used with the spray device
Chronic bodily pain after lung transplantation has received little attention. Therefore, the aim was to provide a multidimensional assessment of self-reported chronic pain 1-5 years after lung transplantation and its relationship with self-reported psychological general well-being (PGWB) and self-efficacy. This multicenter, cross-sectional study is a part of the Swedish national study: Self-manage
We present results from an inter-laboratory massively parallel sequencing (MPS) study in the framework of the SeqForSTRs project to evaluate forensically relevant parameters, such as performance, concordance, and sensitivity, using a standardized sequencing library including reference material, mixtures, and ancient DNA samples. The standardized library was prepared using the ForenSeq DNA Signatur
Rationale, aims, and objectivesDrug‐related morbidity is common, which results in suffering for the patients and a high cost to society. SÄKLÄK2 is a multi‐professional intervention model aiming at improving drug safety in primary health care. The objective of this study was to elucidate the perceptions of the participants' regarding the efficiency of the intervention and the feasibility to introd
To meet future challenges in urban development with denser housing and sustainable water resources, society needs to take actions. Densification of housing is met by expanding housing into old industrial areas often contaminated and water resources are already affected in some areas by over exploiting, pollutants spreading and a changing climate leading to changes in recharge.Growing concerns are
We have studied the geometry and electronic structure of the P-cluster in nitrogenase in four oxidation states: PN, P1+, P2+, and P3+. We have employed combined quantum mechanical and molecular mechanical (QM/MM) calculations, using two different density-functional theory methods, TPSS and B3LYP. The calculations confirm that the side chain of Ser-188 is most likely deprotonated in the partly oxid
