Background: HIV-1 infection is associated with an increased incidence of and mortality from tuberculosis. Few community studies have examined the effect of HIV-2 on tuberculosis. Methods: We investigated the association between HIV-1, HIV-2 and active tuberculosis in four districts (population 42 709) in Bissau, capital of Guinea-Bissau, with the highest known seroprevalence of HIV-2 infection in
The purpose of Experimentation in Software Engineering: An Introduction is to introduce students, teachers, researchers, and practitioners to experimentation and experimental evaluation with a focus on software engineering. The objective is, in particular, to provide guidelines for performing experiments evaluating methods, techniques and tools in software engineering. The introduction is provided
The Swedish Pompeii Project started in 2000 as a research and fieldwork activity initiated by the Swedish Institute in Rome. The aim was to record and analyze an entire Pompeian city-block, Insula V 1. Since autumn 2011 a new branch of advanced digital archaeology, involving 3D reconstructions and documentation methods, was added to the project agenda. The insula was completely digitized using las
As a result of the reorganization of Lund Institute of Technology at Lund University, the new Department of Design Sciences was established. In focus of the establishment of this Department was the ambition to facilitate cross-disciplinary research within the design area. The project presented here is one of the first results of this ambition. In this project the overall objective is the increase
Popular Abstract in Swedish Polymerer är samlingsnamnet på långa molekylkedjor. Runt omkring oss i vårt dagliga liv är vi omgärdade av polymerer så som plaster, lim, fibrer och proteiner. Utvecklingen av många högteknologiska produkter är starkt beroende av polymera material. Grundläggande kunskaper om dem och deras egenskaper är därför viktigt. I ett batteri kan många fördelar erhållas då den koThere is a growing need for multifunctional polymeric materials for the development of several important energy conversion technologies. For example, the polymer electrolyte is a key component in lithium polymer batteries. The basic functions of this electrolyte are to efficiently conduct the lithium ions and physically separate the electrodes. Consequently, these electrolytes should ideally posse
BACKGROUND: Studies of cardiovascular deconditioning are primarily carried out after experimental bed rest. No previous study has followed the cardiovascular effects of decreased and resumed physical activity in athletes after acute physical injury and convalescence. Anterior cruciate ligament (ACL) injury causes a significantly decreased activity level over a long period, making it an ideal model
Temperatures in the Arctic regions are rising, thawing permafrost and exposing previously stable soil organic carbon (OC) to decomposition. This can result in northern latitude soils, which have accumulated large amounts of OC potentially shifting from atmospheric C sinks to C sources with positive feedback on climate warming. In this paper, we estimate the annual net C gas balance (NCB) of the su
BACKGROUND: Selective cerebral perfusion (SCP) is used for extending the period during which surgical procedures can be safely performed. We sought to determine the direct effects of pH management on cerebral microcirculation and metabolism during SCP. METHODS: An experimental SCP porcine model was created by selectively allowing cold perfusate only into the bicarotid brachiocephalic trunk during
Obesity is associated with a risk of at least 20 different cancers. We aimed at defining cancer risks in prospectively recruited patients with a novel subgroup, those with a family history of obesity. We defined a cohort of 30 020 patients who had been hospitalized since 1964. Cancer risks in these patients were followed through 2006. Standardized incidence ratios were calculated for cancer using
Objective:To examine the impact of non-response to self-reported body weight and height in health questionnaires for the estimation of obesity prevalence.Methods and Procedures:A cross-sectional population-based health survey in the community ofVara with 16,009 residents (in year 2002) in South-western Sweden. Participants randomly selected in strata by sex and age among residents being 30-74 year
BACKGROUND: Risk of coronary heart disease (CHD) in cancer patients has not been thoroughly investigated. The aim of the present study was to examine whether there is an association between cancer and first hospitalisation for CHD. METHODS: All individuals in Sweden with a diagnosis of cancer between 1st January 1987 and 31st December 2008 were followed for first hospitalisation for CHD. The refer
We present a theoretical study of high-order harmonic generation by a slowly driven ''Duffing'' anharmonic oscillator. The power spectra are shown to display a plateau of high harmonics, which ends up with a sharp cutoff. The classical dynamics is analyzed with the adiabatic invariance theorem, which yields a simple interpretation to this characteristic behavior. We compare with the quantum case b
BACKGROUND: Changes in P-wave morphology have recently been shown to be associated with interatrial conduction route used, without noticeable changes of P-wave duration. This study aimed at exploring the association between P-wave morphology and future atrial fibrillation (AF) development in the Multicenter Automatic Defibrillator Trial II (MADIT II) population. METHODS: Patients included in MADIT
Objective. Chronic obstructive pulmonary disease (COPD) continues to be an important cause of morbidity, mortality and healthcare costs in the western world. Although smoking is an important trigger of COPD, other factors such as chronic inflammation and malnutrition are known to influence its development. Because coeliac disease (CD) is characterized both by dysregulated inflammation and malnutri
