Many extensions of the Standard Model posit the existence of heavy particles with long lifetimes. In this Letter, results are presented of a search for events containing one or more such particles, which decay at a significant distance from their production point, using a final state containing charged hadrons and an associated muon. This analysis uses a data sample of proton-proton collisions at
BACKGROUND: There was a decrease 1982-2001 in smoking during early pregnancy in Swedish women. We sought to determine whether there was a parallel decrease in socio-economic inequality in smoking. METHODS: Registry data indicating educational level and smoking status at first antenatal visit in all 2,022,469 pregnancies in Sweden 1982-2001 was analysed. Prevalence differences, odds ratios based on
B vitamins and polymorphisms in genes coding for enzymes involved in one-carbon metabolism may affect DNA synthesis and methylation and thereby be implicated in carcinogenesis. Previous data on vitamins B2 and B6 and genetic polymorphisms other than those involving MTHFR as risk factors for gastric cancer (GC) are sparse and inconsistent. In this case-control study nested within the European Prosp
Family caregivers in palliative care have a need for knowledge and support from health professionals, resulting in the need for educational and supportive interventions. However, research has mainly focused on the experiences of family caregivers taking part in interventions. To gain an increased understanding of complex interventions, it is necessary to integrate the perspectives of health profes
BACKGROUND: Patterns of spatial variation in discrete phenotypic traits can be used to draw inferences about the adaptive significance of traits and evolutionary processes, especially when compared to patterns of neutral genetic variation. Population divergence in adaptive traits such as color morphs can be influenced by both local ecology and stochastic factors such as genetic drift or founder ev
Two searches for supersymmetric particles in final states containing a same-flavour opposite-sign lepton pair, jets and large missing transverse momentum are presented. The proton-proton collision data used in these searches were collected at a centre-of-mass energy root s = 8TeV by the ATLAS detector at the Large Hadron Collider and corresponds to an integrated luminosity of 20.3 fb(-1). Two lept
Trinidad and Tobago is a country with a long history in the hydrocarbon industry. This makes the country one of the wealthiest in the Caribbean region and most poised to be at the edge of innovation and sustainable technology use. However, unsustainable urban development practices have resulted in increasing negative impacts. Governments world-wide have been introducing policies and regulations to
BACKGROUND: The management of femoral neck fractures (FNF) in elderly patients depends on comorbidities, pre-fracture mobility, any hip joint disease, and life expectancy, with treatment typically involving either hemiarthroplasty (HA) or total hip arthroplasty (THA). While cemented femoral stem fixation is standard, there is no clear consensus regarding cemented versus cementless cup fixation in
Water is arguably the world’s most valuable endangered resource, the management of which has been subject of contentious debate that in recent years has gained growing political, economic and media attention. This study intends to make use of that momentum by constructing a framework for quantifying global water crisis risk that is applied to assess both the EU’s share of such risk and the success
In this thesis an optimization of a previously performed inclusive search for beyond Standard Model Physics in same-sign di-lepton final states is performed, but tuned for a doubly-charged Higgs boson decaying to same-sign di-muons. The doubly-charged Higgs boson is a proposed fundamental particle whose existence would provide evidence for theoretical extensions of the Standard Model (SM) of parti
The purpose of this thesis was to examine climate related human mobility in the Southern Africa Development Community (SADC). The adverse effect of climate change in SADC is mainly linked to increasing rainfall variability and a higher frequency or intensity of floods and droughts. These effects are a major challenge for human security. Climate change has emerged as one of the most pressing, unres
Soil as a fundamental, conditionally renewable natural resource is increasingly under threat from unsustainable farming practices in a changing environment. In Hungary, expansive areas of land are susceptible to soil degradation, while only a small percentage of farmers currently applies soil conservation practices (SCPs). Degraded soils have an impact on food production, climate adaptation, clima
Objectives: Romania joined to European Union (EU) in 2007. Consequently, the number of EU citizens of Roma descent increased in Sweden as the movement of freedom was granted. This study attempts to understand the conceptualisation and reason for underreporting hate crimes in Malmö, Sweden. Methods: Qualitative data collection methods of semi-structured interview and participant observation were e
Clin Microbiol InfectAbstract The usefulness of spa typing was evaluated in relation to pulsed-field gel electrophoresis (PFGE), as a tool for epidemiological typing of methicillin-resistant Staphylococcus aureus (MRSA) in a low-prevalence region in southern Sweden. Bacterial isolates from 216 MRSA cases, newly identified in 2000-2004, were studied. The isolates were obtained from infected patient
Health related quality of life (HRQoL) was assessed in the randomised, prospective ARTSCAN study comparing conventional radiotherapy (CF) with accelerated radiotherapy (AF) for head and neck cancer.
A European web-based registry for refractive surgery was established in 2008; The European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO). The aim of the registry was to improve treatment and standards of care for refractive surgery. Further aims were to offer a tool for benchmarking by establishing a reference database and for surgeons to enter and analyze their own ou
OBJECTIVE: The time after birth is a crucial period for women, involving both physical recovery and emotional challenges. Previous research indicates that postnatal care is a neglected area of maternity care. The aim of this study was to explore women's suggestions for health care improvements, based on their experiences during the first year after birth.METHODS: This study is based on data from a
The Swedish Quality Registry for Pain rehabilitation (SQRP) is a well-established clinical registry for adult patients with complex chronic pain conditions. SQRP registers patient-reported outcome measures from a majority of specialist chronic pain units/departments in Sweden. Up to four International Classification of Diseases version 10 (ICD-10) diagnoses can be registered in SQRP. The aim of th
Accurate eye tracking is crucial for gaze-dependent research, but calibrating eye trackers in subjects who cannot follow instructions, such as human infants and nonhuman primates, presents a challenge. Traditional calibration methods rely on verbal instructions, which are ineffective for these populations. To address this, researchers often use attention-grabbing stimuli in known locations; howeve
