Today's power plants are shifting their combustion toward a more complex fuel mix on the grounds of environmental impact, cost, availability and regulations. Certain new types of fuel can be classified into the following groups: herbaceous material (straw and grass), agricultural by-products (pits, shells and hulls), wood, and waste fuels. These fuels contain various amounts of alkali metals, main
Natural products are compounds that exist naturally in living organisms, e.g.,plants, animal and fungi. These compounds are likely biologically active and canbe used as pharmaceuticals for various diseases. Evolution has made it possible forliving organisms to produce these natural products as a defence mechanism againstvarious threats. In most cases, the organism only produces a small amount of tThis thesis describes our efforts towards the total synthesis of natural products and the development of a newmethodology to afford a synthetically important scaffold.Chapter 2 outlines our efforts towards the total synthesis of a marine natural product, perophoramidine as wellas our completed synthesis of dehaloperophoramidine. The focus of the studies was to develop an efficient andconcise strat
Direct numerical simulations (DNS) of low and high Karlovitz number (Ka) flames are analysed to investigate the behaviour of the reactive scalar sub-grid scale (SGS) variance in premixed combustion under a wide range of combustion conditions (regimes). An order of magnitude analysis is performed to assess the importance of various terms in the variance evolution equation and the analysis is valida
This licentiate thesis is in the field of biomedical signal processing with main focus on processing of cardiac signals measured on the body surface or invasively from patients with atrial fibrillation (AF). The first part addresses spatial analysis of AF using VCG data synthesized from the 12-lead ECG. Two parameters each are extracted to characterize the spatial orientation as well as the spatia
A high-pressure tank rupture is a challenging scenario requiring attention in most hydrogen applications. A common cause of rupture is an external fire heating the tank, causing increased internal pressure and/or reduction in the tensile strength of the tank material (with the relevance of each depending on tank material).Most of the available methods for prevention of such ruptures have been deveA high-pressure tank rupture is a challenging scenario requiring attention in most hydrogen applications.

Little is known about the neural basis of lower and higher-order olfactory functions such as odor memory, compared with other sensory systems. The aim of this study was to explore neural networks and correlates associated with three functions: passive smelling (PS), odor encoding (OE) and in particular odor recognition memory (ORM). Twenty-six healthy participants were examined using fMRI conducte
There is currently interest in low strain HPHT diamond due to its expected application as various types of X-ray optical elements at Synchrotrons, where the X-ray intensity is becoming progressively too severe for the existing materials. The diamond crystals need to be synthesised with unprecedented lattice quality. In recent measurements at the ID19 beamline of European Synchrotron Radiation Faci
Renovation of water and central heating pipelines is a very costly and time-consuming process, so a way to prioritize the limited resources between different parts of the systems is very important. The risk for corrosion damage can be assessed from the resistivity of the ground, due to the processes facilitating the metal oxidation also affecting the resistivity, but galvanic resistivity mapping i
Research Question/Issue: On the basis of a dynamic interrelation between the assumptions of agency theory and stewardship theory, this study seeks to make sense of disobedience at the highest corporate level. Departing from a processual view in order to better understand how loyalty plays a critical role in the relationships between a CEO and his/her principal, we propose a conceptualization of th
SETI, our hopes or fears of a future contact with ETI, is a modern expression of an unending human obsession with the rise and fall of civilizations. People across the globe from our earliest sources to our contemporary culture have tried to understand the beginning and end of history, the creation and the doom. Factor L of the Drake Equation could in other words be understood in a longer historic
The definition of Validation and Verification (V&V) tests for analysing evacuation model capabilities is the object of a large debate among researchers given the lack of an international standard. Four main types of tests have been reported in the literature, 1) component testing, 2) functional verification, 3) qualitative verification and 4) quantitative validation. An important issue relates
Popular Abstract in Swedish FN:s barnkonvention formulerar barns och ungas behov i termer av mänskliga rättigheter. Sverige ratificerade konventionen efter ett beslut i riksdagen den 21 juni 1990, utan att reservera sig på någon punkt. Konventionens budskap kan sammanfattas i tre ord: Barn skall respekteras. Vuxna skall se barnet, sträva efter att förstå det och vidta åtgärder som bedöms vara till
Biocatalysis in organic media offers very attractive methods to prepare fine chemicals. The biocatalyst performance regarding activity, stability and enantioselectivity will determine the viability of the bio-process. Therefore, the understanding and optimization of the parameters influencing enzyme performance in organic solvents are extremely important. In this thesis, reactions catalysed by hyd
Cities are key actors in reducing both the causes of climate change (mitigation) and its impact (adaptation), and many have developed separate mitigation and adaptation strategies and measures. However, in order to maximize outcomes, both scholars and practitioners are increasingly calling for more integrated and synergetic approaches. Unfortunately, related research remains scarce and fragmented,
The house sparrow is an important model species for studying physiological, ecological and evolutionary processes in wild populations. Here, we present a medium density, genome wide linkage map for house sparrow (Passer domesticus) that has aided the assembly of the house sparrow reference genome, and that will provide an important resource for ongoing mapping of genes controlling important traits
The home has a self-evident place within audience studies. In spite of this salient position, the home has seldom been theoretically problematized; it has often been ‘reduced’ to a social context of the prioritized media engagement (domestication research is partly an exception). The paper is further justified by the fact that media and media practices are important for the home and its boundaries
The creation of an efficient public transport system increasingly requires collaboration between independent organizations. Institutional reforms in Europe have created governance situations where collaboration between organizations is a critical issue, and examples include the integration of transport and land-use planning and the planning of large public transport projects. The organizational co
