Abstract The main influences on growing conditions in pastures and hayfields are grazing and mowing, which regulate the species struggle for space and resources. If the management ceases, this will contribute to a change of the vegetation. A succession starts where the plant cover gradually will change according to a specific pattern. After some time a few competitive species, previously disfavou
Shale gas extraction commonly known as fracking had support from the UK government with their ‘all out for shale’ policy. Despite this industry has struggled to establish itself mainly due to strong opposition from communities concerned about environmental and health impacts. Most research into the impacts of fracking is concerned with either environmental degradation or physical health impacts wh
Sustainability researchers are facing increasing pressure to improve their scientific communication and to achieve impacts in wider society with their research. Knowledge mobilisation (KMB) is a key component of both challenges, as it relates to efforts undertaken by researchers to achieve impacts with their research. This study seeks to identify some of the KMB practices being undertaken by exper
In providing public goods, the government confronts challenges in determining the optimal pricing strategy due to the lack of information on individual preferences and the propensity of consumers to misreport their true valuations. Decentralisation of fiscal authority could be a partial solution to this problem, as lower government levels have better access the diverse regional and local preferenc
Purpose: In one form of human autosomal recessive retinitis pigmentosa and in retinal degeneration (rd1) mouse, mutation occurs in the genes encoding ß subunit of rod photoreceptor cGMP phosphodiesterase. Therefore, rd1 mutant mouse is an appropriate model for human inherited retinal degeneration studies. Retinal explants are successfully cultured in serum free chemically defined R16 medium to eva
Immunoglobulins (Ig), particularly IgE, are believed to be crucially involved in the pathogenesis of asthma and, equally, in allergic models of the disease. To validate this paradigm we examined homozygous mutant C57BL/6 mice, which are B cell deficient, lacking all Ig. Mice were immunized intraperitoneally with 10 micrograms ovalbumin (OVA) plus alum, followed by daily (day 14-20) 30 min exposure
CYP17 encodes cytochrome p450c17 alpha, which mediates activities essential for the production of sex steroids. Common germ line variation in the CYP17 gene has been related to inconsistent results in breast and prostate cancer, with most studies focusing on the nonsynonymous single nucleotide polymorphism (SNP) T27C (rs743572). We comprehensively characterized variation in CYP17 by direct sequenc
Deteriorating water quality is a challenge which affects people of the entire world, with a growing population and increased industrialization worldwide. The problem is especially apparent in many developing nations where water resource management must be improved to secure a future sustainable supply. This study was undertaken as a bachelor degree within the MFS-program funded by SIDA. The study
Outdoor climate has considerable impact on the indoor climate and it is therefore important to adapt the buildings to the climate. This thesis shows how to improve indoor climate in a climate which it is hot, dry in the summer and cold in the winter. My investigative unit is a middle class house in the town Baalbek in Lebanon and the purpose of the study is to come up with proposals on possible so
This report is a fire safety assessment of Bråhögshallen, a multi-sport facility located in Staffanstorp in the south of Sweden. The building consists of one larger and one smaller sports hall, a bowling alley and other smaller facilities used for a variety of different sports. Bråhögshallen was built in 1969, and the regulations regarding fire safety has since changed. The assessments in this rep
BACKGROUND: The widespread use of intramedullary nails (IMNs) compared with sliding hip screws (SHSs) in extracapsular hip fractures (AO/OTA 31-A1, 31-A2, 31-A3) has been questioned because of a higher complication rate, although the outcome might have improved through more recent implant designs and the learning curve. This study aimed to investigate if there is a difference with regard to the cu
Background: Adolescent pregnancy and associated neonatal mortality are major global health challenges. In low-income settings where 90% of the 21 million global adolescent pregnancies occur, half are unintended and a fifth experience unsafe abortion. In Kenya, Uganda, and Tanzania, the survival patterns of neonates born to adolescents are unclear.Objectives: To assess survival patterns among neona
Biogeochemical cycling of silicon (Si) in the Barents Sea is under considerable pressure from physical and chemical changes, including dramatic warming and sea ice retreat, together with a decline in dissolved silicic acid (DSi) concentrations of Atlantic inflow waters since 1990. Associated changes in the community composition of phytoplankton blooms will alter the material comprising the deposit
Introduction Diabetes mellitus is one of the most common non-communicable diseases and is the fifth leading cause of death in most developing countries. Regular physical activity (PA) is strongly recommended for individuals with diabetes for its beneficial effects in improving blood glucose control and insulin sensitivity, prevention and reduction of morbidities and complications, and its cardiova
BACKGROUND: Lead exposure has been associated with increased incidence of adverse clinical cardiovascular outcomes. Atherosclerosis has been suggested as one of the underlying mechanisms, and findings from experimental studies support this, but human data are scarce. OBJECTIVES: Our objective was to determine the association between environmental lead exposure based on blood lead (B-Pb) concentrat
Objective: To identify prognostic factors for patients with advanced persistent, recurrent, or 2nd primary oral cavity squamous cell carcinoma (OCSCC) potentially unsuitable for salvage surgery with free tissue flap (FTF) reconstruction. Materials and methods: A population-based cohort of 83 consecutive patients with advanced OCSCC who underwent salvage surgery with FTF reconstruction at a tertiar
IMPORTANCE: Discontinuation and nonpublication are established sources of avoidable waste among surgical trials, but rates of delayed completion and recruiting shortfalls remain unclear.OBJECTIVES: To examine the rate of delayed completion, incomplete enrollment, and discontinuation among randomized clinical trials in surgical populations and the duration of delays and extent of recruiting shortfa
Studies have indicated that transportation noise is associated with higher cardiovascular mortality, whereas evidence of noise as a risk factor for respiratory and cancer mortality is scarce and inconclusive. Also, knowledge on effects of low-level noise on mortality is very limited. We aimed to investigate associations between road and railway noise and natural-cause and cause-specific mortality
INTRODUCTION: The Five Self-Harm Behavior Groupings Measure (5S-HM) is a novel assessment that evaluates behaviours which may go undetected by existing measures. Self-harm is formulated across directness and lethality spectra, including under-studied behaviors such as indirect self-harm, harmful self-neglect and sexual self-harm. Aims of the study were to: (1) empirically evaluate the 5S-HM; (2) t
BACKGROUND: Most cerebral palsy (CP) cases have an unexplained etiology, but a role for environmental exposures has been suggested. One purported environmental risk factor is exposure to endocrine-disrupting pollutants specifically per- and polyfluoroalkyl substances (PFAS).OBJECTIVES: We investigated the association between prenatal PFAS exposures and CP in Swedish children.METHODS: In this case-
