Background A 1-h algorithm based on high-sensitivity cardiac troponin T (hs-cTnT) testing at presentation and again 1 h thereafter has been shown to accurately rule out acute myocardial infarction. Objectives The goal of the study was to evaluate the diagnostic accuracy of the 1-h algorithm when supplemented with patient history and an electrocardiogram (ECG) (the extended algorithm) for predicti
Purpose To explore demand related information sharing in a multi-tier supply chain and propose contingency factors that impact benefits of information sharing across three or more tiers. Design/methodology/approach Through an in-depth case study a range of methods are used to collect data from companies representing three different tiers, including focal company, 1st tier suppliers and 1st tier c
In this thesis, I have studied when an initially monomorphic population can diverge into two morphs in a heterogeneous environment. Evolution is driven by competition for resources or predation. In Paper I, we studied source-sink dynamics during evolution in an environment with two types of resource of different abundance in two habitats. We found that dispersal can help maintain higher diversity
Catalytic incineration is one of the methods to reduce the emissions of CO and VOCs. Low operation temperature and low catalyst cost are essential parameters for catalytic incinerators. Pt/Al2O3 catalysts are frequently used today, but the cheaper metal oxide catalysts can be very competitive if comparable overall activity is obtained. This thesis concerns how it is possible to decrease the operat
Purpose of this paper: The cluster thinking in the humanitarian world has been suggested as a solution to the lack of coordinated disaster response in the past 10 years. Clusters on diverse functions including sheltering, logistics and water sanitation can be viewed as an effort of functional coordination, i.e. horizontal coordination within a functional area. The purpose of this paper is to contr
This thesis consists of four studies that deal with how individual outcomes are shaped by social interactions. The scope of the thesis ranges from relationships between individuals in what is arguably the most fundamental building block in society today — the family — to more generalized relationships between different groups in society. The first study examines whether twins’ inferior health at
Objective: Cardiovascular disease can be prevented through lifestyle changes, but such changes are often hard to attain. Text message interventions with lifestyle advice have shown small but promising effects. Our objective was to explore participant experience of a text message lifestyle intervention for patients with hypertension, and implications for future lifestyle interventions. Design and s
BackgroundDiagnosing sepsis remains a challenge because of the lack of gold-standard diagnostics. Since there are no simple, broadly accepted criteria for infection, there is a risk of misclassifying sepsis patients (sepsis mimics) among patients with organ failure. The main objective of this study was to investigate the proportion of non-infected patients (sepsis mimics) in ICU patients with pres
Solid insulin formulations obtained by different methods of preparation were compared with respect to chemical stability and morphology. Spray- and freeze-drying, solution enhanced dispersion by supercritical fluids (SEDS) and precipitation into starch microspheres were the methods used for preparation of solid powders. The excipients applied were melezitose, starch, and sodium taurocholate. The s
BACKGROUND: Central sensitization has been suggested as an explanation of the wide range of gastrointestinal and extraintestinal symptoms commonly seen in irritable bowel syndrome (IBS). In this study, the presence and level of central sensitization, and its association to gastrointestinal (GI) symptoms were explored in IBS in comparison with control groups.METHODS: We investigated patients with I
The characteristics of an Elekta amorphous silicon (a-Si) electronic portal imaging device (EPID) in response to a 6 MV photon beam generated without a flattening filter, an unflattened beam, have been determined. The characteristics were then compared to those for a conventional photon beam generated with a flattening filter in the beam, a flattened beam, in order to determine the suitability of
The ability to generate and control movement is essential for human interactions and overall well-being. Neuromuscular impairment caused by neurological injuries and diseases, such as stroke or limb amputation, severely limits the ability of affected individuals to interact with the surrounding environment, necessitating advanced strategies for rehabilitation and restoration of motor function. Vol
Businesses play a key role in transforming production and consumption for sustainability,where circular business models (CBMs) offer one solution to reduce waste and rethink resource use.Although CBMs may be able to provide environmental and economic benefits, it is unclear how they canbe implemented effectively and contribute to sustainability goals. To understand how CBMs cancontribute to broade
This thesis theoretically investigates electronic transport in different low dimensional nanostructures. The miniaturization of electronics means that we reach a limit where quantum effects play a role in electronic devices. To understand and improve electronics at this level it is important to understand the transport properties. Excellent control over the nanostructures also makes them a great p
This report summarises the results from an interview and literature study carried out to identify key individual qualities for collective problem-solving in a fire and rescue service context. The report contributes to the research project FIRE21 (Fire and Rescue Services in the 21st Century) and is part of a work package looking into such individual qualities through using different methods and ma
In his dissertation Blomberg (2004) investigates into how the care manager reform is incorporated into organizational practice in the care of older people in Sweden. He shows that it is made through different lines of argumentations following one another. Through applying neo-institutional theory this can be understood as “solutions seeking problems to solve” rather than the other way around. In t
Popular Abstract in Swedish Denna avhandling består av sex kapitel. Det första kapitlet är en introduktion medan de resterande fem innehåller avhandlingens huvudsakliga bidrag. De tre första kapitlen är samförfattade med Joakim Westerlund. Kapitel två har sin utgångspunkt i Westerlund (Empirical Economics 37:517-531, 2009) som visar på en svaghet i det populära LLC (Levin et al. Journal of EconomThis thesis is divided into two distinct parts. The first part contains three chapters, co-authored with Joakim Westerlund, that deal with the analysis of unit root testing, and the second part consists of two chapters on slope homogeneity testing. Chapter 2 continues and extends the analysis in Westerlund (Empirical Economics 37:517–531, 2009), who demonstrates that the performance of the popula
