OBJECTIVES: To evaluate the outcome of treatment for deep sternal wound infection (DSWI) in a nationwide patient cohort, before and after the introduction of negative-pressure wound therapy (NPWT). METHODS: This was a population-based cohort of all patients treated for DSWI in Iceland out of 2446 open heart operations performed between 2000 and 2010. Length of hospital stay, survival and reoperati
Pollen and spore analysis is the most successfully used palaeobotanical discipline for reconstructing Holocene vegetation and climate history throughout the world. Subantarctic islands are very specific areas. They are located in the circum-Antarctic Southern Ocean in latitudes that are under strong influence of the southern westerly winds, and are characterised by a treeless, phanerogam-poor flor
A crucial stage in the interaction between pollinators and plants is the moment of physical contact between them, known as flower inspection, or handling. Floral guides - conspicuous colour markings, or structural features of flower corollas - have been shown to be important in the inspecting behaviour of many insects, particularly in diurnal species. For the nocturnal hawkmoth Manduca sexta tacti
Using laser-Doppler flowmetry during ventriculocisternal perfusion with inulin-[14C]carboxylic acid, choroid plexus blood flow (CPBF) and CSF production were measured simultaneously in rats during periods of 3 h. Blood flow and CSF production decreased only slightly during control experiments. The effect of vasoactive intestinal polypeptide (VIP) was studied at different concentrations of the pept
There is no consensus on the treatment of congenital diaphragmatic hernia (CDH), and practice seems to vary between centres. The main purpose of the present study was to survey current practice in Scandinavia. Thirteen paediatric surgical centres serving a population of about 22 million were invited, and all participated. One questionnaire was completed at each centre. The questionnaire evaluated
A flexible method of preparing and macroscopically aligning nanoparticles of crystalline silver into millimeter long fibers is presented. The approach utilizes the dual functionality of a reverse hexagonal liquid crystalline template containing a built-in reducing agent facing the aqueous domain. The method is advantageous in that its slow kinetics allows for a thorough introduction of a silver sa
Purpose: Retigabine is a novel anticonvulsant drug that not only augments gamma-aminobutyric acid mechanisms, but also opens voltage gated K+ channels (KCNQ). In this study we investigated the effects of retigabine on detrusor activity in rats. Materials and Methods: To conscious, female Sprague-Dawley rats undergoing continuous cystometry retigabine was given intravenously (0.5, 1 and 5 mg/kg(-1)
1. Mechanical transients in fibre bundles of skinned smooth muscle of guinea-pig taenia coli at 21-22 degrees C were investigated by recording tension responses to length changes of up to 9%, complete within 0.3 ms. 2. The length-force relationship, recorded continuously during rapid stretch of a Ca(2+)-activated contracted muscle, was linear up to at least 2.5 times the isometric force, correspon
The creative economy (CE) has recently been at the forefront of Indonesia’s development agenda. By harnessing human creativity and cultural resources, there is considerable potential for CE and the creative and cultural industries to contribute to economic growth and generate employment opportunities for the country’s expanding working-age population. However, the virtues of CE have largely been e
Grundprincipen att "avtal ska hållas" är en central del i avtalsrätten. Frågan gällande ändrade förhållanden och dess inverkan på avtal har därför länge varit ämne för diskussion. I en långvarig avtalsrelation är det svårt att förutse risken för förändringar som kan drabba avtalet och avtalsrelationen. Frågan väcks i ett sådant sammanhang om vilka möjligheter avtalsparter har att regleraThe fundamental principle that "agreements must be kept" is a central part in contract law. How "changed circumstances" can impact an agreement has long been a subject for discussion. In long-term agreements, it is difficult to determine what risks that can impact an agreement. The question of possibilities available to handle such a situation, where the agreement can be regula
In recent years, the use of childcare especially in rich countries, has gone through a huge development. Well-established theories and previous research suggest that the social infrastructure has a positive impact on economic growth and that there is a positive relationship between childcare and equality. However, studies about how childcare affects economic growth are scarce. The aim of the study
En bättre förståelse över ytproteiner på dendritiska subtyper Av Zackarias Söderlund Immunförsvaret ska se till att kroppen dödar inkräktare såsom virus och bakterier men även kroppens egna celler som omvandlats till tumörceller. Dendritiska celler har en viktig roll i detta då de ständigt skannar sin omgivning och instruerar resten av immunförsvaret om påträffande organismer/celler ska tolereraThe development of vaccines against tumours are gaining increased attraction and one strategy to increase the efficiency of these vaccines is to target the antigen or drug to cell surface receptors on dendritic cells (DC), such as the C-type lectin receptors (CLR). To this end, knowledge of the expression levels of CLR on DC subsets is important and it has been studied in different tissues and blo
Adapting to climate change is a growing policy area and today more municipalities see a future need of protecting themselves against rising sea levels, floods and higher temperatures. In 2012 the city of Malmö took a significant step when adopting a strategy plan where actions where pointed out and prioritized. But the plan was three years later neither pursued nor prolonged. By using the advocacy
De ständigt ökande klimatförändringarna orsakade av människan har visat sig medföra enorma komplikationer för stora delar av världen. Insatser som syftar till att bekämpa de negativa klimatförändringarna som har uppstått till följd av växthusgasutsläpp utvecklas nu på allvar och de negativa effekterna kan bland annat dämpas genom en effektivare energianvändning. I det moderna samhället står byggnDue to the constantly increasing threat caused by climate change necessary measures against the current situation needs to be accomplished. This study shows that one potential approach to reach this goal is by a more effective way of energy consumption. In this study the energy use of students in the city of Lund in Sweden was assessed. The purpose of the study was to find out what sort of driving
Det är vanligt förekommande att fysiska och juridiska personer vill minska sin beskattning. Det finns stor variation i förfaringssätt som medför minskad beskattning. Denna uppsats undersöker om dubbel skattefrihet kan uppstå vid hemvistbyte. Dubbel skattefrihet innebär att varken den nya eller tidigare hemviststaten beskattar personen. På så sätt blir vissa inkomster skattefria. Det har tidigare f

Methodology: Qualitative research method using primary data (interviews with former and current employees) and secondary data. Findings: In this paper, there are several findings derived from an employee perspective and
Hållbarhet och kommunal acceptans för vindkraft. Klimatförändring och energiomställning – den ena nämns sällan utan den andra. En av vår tids mest aktuella frågor som berör alla delar av vårt samhälle. Sverige behöver mer förnybar el. Men samtidigt som tidsramen för att hålla den globala medeltemperaturen under 1,5 °C blir allt mindre avslår svenska kommuner allt fler vindkraftsparker då det finnDue to climate change, the transition to renewable energy systems has become increasingly urgent, and wind power has been identified as a significant facilitator in the transition of Swedens energy system. However, the rapid development of wind power has resulted in increased levels of local resistance, where the socioeconomic consequences on local communities have been highlighted by politicians,
Public diplomacy, public relations, propaganda, and strategic narratives are all under the ‘umbrella’ of soft-power and nowadays’ international relations. Strategic narratives currently represent one of the most essential tools that political actors use to increase their influence on local and foreign audiences, gain public support, and lastly achieve their foreign policy objectives. This disser
The increasing use of 5G networks and their application in critical services makes them vulnerable to Distributed Denial of Service (DDoS) attacks. This thesis investigates the detection and mitigation of DDoS attacks in 5G networks using machine learning (ML) methods. In particular, it analyses two exciting convolutional neural network (CNN)-based models: the LUCID model and the Mohak model, and
