Objectives: Open abdomen (OA) treatment is sometimes necessary after surgery for aortic aneurysm (AA), to prevent or treat abdominal compartment syndrome (ACS). A multicentre study evaluating vacuum-assisted wound closure (100-150 mmHg) and mesh-mediated fascial traction (VAWCM) was performed. Methods: All patients treated with OA after AA repair (2006-2009) were prospectively registered at four c

Event-based control is a promising concept for the design of resource-efficient feedback systems, where events such as sampling, actuation, and data transmissions are triggered reactively based on monitored control performance rather than a periodic timer. In this thesis, we investigate how sampling and communication events should be triggered to fully exploit the potential of event-based control

Context: The age-related decline in dehydroepiandrosterone (DHEA) levels is thought to be of importance for general and vascular aging. However, data on the association between DHEA and mortality are conflicting. Objectives: We tested the hypothesis that low serum DHEA and DHEA sulfate (DHEA-S) levels predict all-cause and cardiovascular disease (CVD) death in elderly men. Design, Setting, and Par

Background: Models describing nuclear fragmentation and fragmentation fission deliver important input for planning nuclear physics experiments and future radioactive ion beam facilities. These models are usually benchmarked against data from stable beam experiments. In the future, two-step fragmentation reactions with exotic nuclei as stepping stones are a promising tool for reaching the most neut

AIMS: To describe the occurrence of psychiatric diagnoses in a specialist care setting in older people with intellectual disability (ID) in relation to those found in the same age group in the general population.METHOD: A cohort of people with ID (n = 7936), aged 55 years or more in 2012, was identified, as was an age and sex-matched cohort from the general population (n = 7936). Information regar

BACKGROUND: Aggregate and risk-stratified perioperative mortality rates (POMR) are well-documented in high-income countries where surgical databases are common. In many low-income and middle-income country (LMIC) settings, such data are unavailable, compromising efforts to understand and improve surgical outcomes. We undertook a systematic review to determine how POMR is used and defined in LMICs

There are several occasions when you come into contact with agreements, for example when you receive research funding from an external funding body or participate in research collaborations with parties outside the University. Agreements are furthermore relevant when you publish your results, or turn your research into an innovation. Short cuts to content on this page:Who approves research-related

A comparative study was performed to reveal differences and relative figures of merit of seven different calculation algorithms for photon beams when applied to inhomogeneous media. The following algorithms were investigated: Varian Eclipse: the anisotropic analytical algorithm, and the pencil beam with modified Batho correction; Nucletron Helax-TMS: the collapsed cone and the pencil beam with equ

To enhance the performance of gas turbine engines, high top-cycle temperatures are desired. However, the temperature is limited by current materials. To achieve the higher performance, and meanwhile maintain the metal temperatures of the combustors, vanes and blades below the allowable limits, sophisticated cooling techniques, such as impingement cooling, film cooling and convective internal cooli

The kallikrein gene family (KLK1-KLK15) is the largest contiguous group of protease genes within the human genome and is associated with both risk and outcome of cancer and other diseases. We searched for copy number variants in all KLK genes using quantitative PCR analysis and analysis of inheritance patterns of single nucleotide polymorphisms. Two deletions were identified: one 2235-bp deletion

AIM: To explore the relationship between neuropsychological outcome and magnetic resonance imaging (MRI) findings in paediatric brain tumour patients surviving more than 10 years. BACKGROUND: Cognitive late sequelae after paediatric brain tumour have a multifactorial origin. Low age at diagnosis, cranial radiation therapy, intrathecal methotrexate treatment and increased intracranial pressure are

In August 2007 we went to New Zealand for a placement at Child Youth and Family Services. There our interest in Family Group Conferences (FGC) took off. FGC is not near as common in Sweden as in New Zealand. Therefore the purpose of this study was to examine how the Social Services in Helsingborg and Höör in Sweden and Belfast in Northern Ireland work with FGC. We had the privilege to go to Belfas

The formation of industry standards for environmental issues and corporate social responsibility is gaining acceptance but the number of successfully implemented programs are few. On an individual level companies have for some time applied company standards or codes of conduct. But on a collective level cooperation seems much more difficult. Although from an economic point of view there are clear

Economic sanctions are defined as the exercise of pressure by one state to produce a change in the political behaviour of another state. Traditional economic sanctions are directed at the entire population of a state whilst targeted sanctions are directed at a state’s individuals. This thesis discusses the application of economic sanctions against Iran by the UN, the EU and the United States. Econ

Background: Risk gene variants for celiac disease, identified in genome-wide linkage and association studies, might influence molecular pathways important for disease development. The aim was to examine expression levels of potential risk genes close to these variants in the small intestine and peripheral blood and also to test if the non-coding variants affect nearby gene expression levels in chi

Environmental factors, including viral infections, may explain an increasing and fluctuating incidence of childhood type 1 diabetes (T1D). Ljungan virus (LV) isolated from bank voles have been implicated, but it is unclear whether LV contributes to islet autoimmunity, progression to clinical onset, or both, of T1D. The aim was to test whether LV antibodies (LVAb) were related to HLA-DQ and islet a

Results of numerical simulations are presented for flow past a stationary circular cylinder at low Reynolds numbers (Re=50-200). The simulations were carried out using a finite-volume code employing a fractional step method with second-order accuracy in both space and time. A sensitivity study on numerical parameters concerning the domain size, grid independence and time step resolution was carrie
