The discipline of epidemiology, which holds major influence on public health policy as well as on clinical medical practice, has in recent decades to a large extent been concerned with the identification of factors and markers of risk for disease. Much health information and intervention is thus informed by a wealth of studies on a variety of risk factors, of which the individual is encouraged to
Dizziness in older people is associated with disability and reduced quality of life. Few studies have investigated how daily life is affected from the older person's perspective. Identifying barriers and resources in daily life could guide health care in how to direct efficient interventions. The aim of this study was to explore older persons' experiences of living with chronic dizziness.
The aim of this thesis was to explore and gain deeper insight into and understanding of mobility in public environments for people with acquired cognitive functional limitations (target group of this thesis) and of reasons why some of them do not use public transport. Using an explorative approach, the target group’s mobility was firstly discussed by experts in focus group interviews. Secondly the
Film cooling effectiveness and its distribution characteristics on the gas turbine blade surface were investigated numerically. Seven rectangular ribs were located on the internal wall, and a film cooling hole had a compound inclined angle. The case with a compound angle of 45 degrees was designed to improve the lateral film cooling effectiveness on the downstream surface. The secondary flow jet f
A search for the Standard Model Higgs boson in the decay channel H -> ZZ(()*()) l(+)l(-)l'l'(-), where l = e, mu, is presented. Proton-proton collision data at root s = 7 TeV recorded with the ATLAS detector and corresponding to an average integrated luminosity of 2.1 fb(-1) are compared to the Standard Model expectations. Upper limits on the production cross section of a Standard Model Higgs boso
Background and purpose The Scandinavian Sarcoma Group (SSG) XIV protocol is based on experience from previous SSG trials and other osteosarcoma intergroup trials, and has been considered the best standard of care for patients with extremity localized, non-metastatic osteosarcoma. We analyzed the outcome in 63 consecutive patients. Patients and methods From 2001 through 2005, 63 patients recruited
It is of central interest in membrane proteomics to establish methods that combine efficient solubilization with enrichment of proteins and intact protein complexes. We have investigated the quantitative and qualitative solubilization efficiency of five commercially available detergents using mitochondria from the yeast Saccharomyces cerevisiae as model system. Combining the zwitterionic detergent
There is a growing interest in the prospects of community energy projects to increase energy access for the world's poor. Yet it is not readily apparent how community energy projects can be organized to be successful in the long-term. By utilizing information from four case studies, this work creates a general framework for organizing community energy projects in developing countries. Using th
The purpose of this study was to understand the influence of mothers’ satisfaction with health care on health seeking behaviour for children under-five. With a qualitative approach, this study used focus group discussions and one-on-one interviews to collect data from thirty seven (37) respondents but the focus was on twenty (27) mothers with children under-five in Okwampa, a small rural community
Anknytningsteorin har sedan länge varit fundamental för utvecklingspsykologin och beskriver hur ett barn har en medfödd förmåga att knyta an till sina vårdnadshavare för närhet och skydd. På senare tid har teorin om kognitiva script visat sig användbar i jakten på att förstå hur individers mentala representationer gestaltar sig. Syftet med denna studie var att undersöka förekomsten och relationen
Forty-three strains of group B streptococci (GBS) of types Ia, Ib, II and III were tested for susceptibility to chlorhexidine in concentrations ranging from 256 to 0.25 mg/l using the agar and tube dilution methods. The strains showed minimum inhibitory concentration (MIC) values ranging from 0.5 to 1 mg/l. Serum added to the test medium (50%) increased the MIC values to 4-8 mg/l, while amniotic f
Glacier retreat caused by global warming alters the hydrological regime and poses far-reaching challenges to water resources and nature conservation of the headwater of Yangtze River, and its vast downstream regions with dense population. However, there is still lack of a robust modeling framework of the “climate-glacier-streamflow” in this water tower region, to project the future changes of glac
The Medical Patients with Enoxaparin (MEDENOX) trial was a randomized, placebo-controlled study that defined the risk of venous thromboembolism (VTE) in acutely ill, immobilized, general medical patients and the efficacy of the low-molecular-weight heparin, enoxaparin, in preventing thrombosis. We performed a post-hoc analysis to evaluate the effect of 40 mg enoxaparin once daily on MEDENOX patien
The purpose of our study was to develop specific, sensitive, objective assays for early detection of disseminated tumour cells in patients with colorectal cancer (CRC). Carcinoembryonic antigen (CEA) and cytokeratin 20 (CK20) were chosen as markers because they are selectively expressed in epithelial cells with maintained expression in CRC. Real-time quantitative RT-PCR assays with RNA copy standa
Neurofibromatosis is associated with mid-aortic dysplasia, renal artery aneurysms and renal artery ostial stenosis, or occlusions in about 1% of cases. We describe a novel approach to recanalize an occluded renal artery in a 10-year-old girl with neurofibromatosis and difficulty in pharmacologically controlling her hypertension. Normally, when reconstruction is required, an open operative techniqu
Differential cross-section measurements are presented for the electroweak production of two jets in association with a Z boson. These measurements are sensitive to the vector-boson fusion production mechanism and provide a fundamental test of the gauge structure of the Standard Model. The analysis is performed using proton–proton collision data collected by ATLAS at s=13TeV and with an integrated
The minimization of a functional composed of a nonsmooth and nonadditive regularization term and a combined L1 and L2 data-fidelity term is proposed. It is shown analytically and numerically that the new model has noticeable advantages over popular models in image processing tasks. For the numerical minimization of the new objective, subspace correction methods are introduced which guarantee the c
