This thesis has investigated the prevailing understanding of poor leadership as a major impediment to the democratization of the Democratic Republic of Congo. Analytical studies found evidences on the correlation between the authoritarian regimes installed in the Democratic Republic of Congo and the abortive process of democratization under the leadership of Mobutu Sese Seko and Laurent-Désiré Kab
The modeling of industrial combustion applications today is almost exclusively based on two-equation turbulence models. Despite its known limitations, the most the widely used model is still the standard k-ε model. The objective of this paper is to investigate the performance of two-equation turbulence models applied to a confined swirling flow. Numerical modeling of an axis-symmetric confined sud
Sediment sequences spanning the last 800 years from two small lakes in the south Swedish uplands were explored for assessment of effects of changing human population, local land-use practices and airborne pollution on lake-ecosystem functioning and resilience. Variations in nutrient cycling and deposition of lithogenic elements were studied, using a multi-proxy stratigraphic approach. Carbon and n
Migratory land birds perform extreme endurance flights when crossing ecological barriers, such as deserts, oceans and ice-caps. When travelling over benign areas, birds are expected to migrate by shorter flight steps, since carrying the heavy fuel loads needed for long non-stop flights comes at considerable cost. Here, we show that great snipes Gallinago media made long and fast non-stop flights (
What is the role of gender in Eastern Christianity? In this volume, Orthodox experts of different disciplines and cultural backgrounds tackle this complex question. They engage critically with gender issues within their own tradition. Rather than simply accepting pervasive assumptions and practices, the authors challenge readers to reconsider historically or theologically justified views by offeri
A common feature within political debate is the decline of parties as organizations. Political theorists have in general, without proper empirical investigation, embraced the idea of the freezing of party systems and of the catch-all party model as the end point of party development. This essay aims to analyze and explain the emergence and increasing amount of political secretaries within Swedish
This thesis investigates the prospects of a common counter-terrorism strategy in the European Union. It analyzes how Member States’ security cultures influence the establishment of a common European counter-terrorism strategy. The study examines the differences between Member States’ security cultures under the framework of social constructivism that emphasizes the impact of the socially construct
This mapping provides an overview of different types of arenas where the two concepts Ecosystem-based adaptation (EbA) and Blue Carbon (BC) are discussed. EbA has been defined by the Convention on Biological Diversity (CBD) as “The use of biodiversity and ecosystem services as part of an overall adaptation strategy to help people to adapt to the adverse effects of climate change.” (CBD, 2009). BC
Disturbances are believed to be one of the main factors influencing variations in community diversity and functioning. Here we investigated if exposure to a pH press disturbance affected the composition and functional performance of a bacterial community and its resistance, recovery and resilience to a second press disturbance (salt addition). Lake bacterial assemblages were initially exposed to r
TEKNOsim is a simple and user-friendly program for analyzing thermal indoor climate and performing annual hourly simulations. The program was originally developed to calculate heating and cooling demands, and indoor climate conditions of a single zone building for peak winter and summer design days. However, TEKNOsim version 6 has been revised to incorporate several new features including annual e
The concern of this paper is with the mediatisation of tourism cities through fast circulating narratives on digital platforms in an era characterised as post-truth involving the spread of fake news and disinformation. Hence far, there is scarce knowledge on how misleading information and false rumours concerning terrorism affect the image of tourism cities. In addition, extant research studies pr
Movement and migration are fundamental parts of the life cycle of most organisms on Earth and occur at an astonishing range of spatial and temporal scales, from iconic pole-to-pole migrations of some birds to diel migrations of enormous amounts of millimeter-sized crustaceans through the waters of oceans and lakes. To move or not to move in a certain situation is a decision that is often taken by
Microbial necromass is increasingly recognized as an important fast-cycling component of the long-term carbon present in soils. To better understand how fungi and bacteria individually contribute to the decomposition of fungal necromass, three particle sizes (>500, 250–500, and <250 μm) of Hyaloscypha bicolor necromass were incubated in laboratory microcosms inoculated with individual strains of t
Ever since the birth of the film medium, the Sámi people, indigenous to Fennoscandia, have been depicted on film. These early films are ethnographic, made from an outsider perspective, depicting the Sámi as exotic and simple. However, in the 1970s, the Sámi became more involved in the filmmaking process, and in 1987, the first Sámi film, Pathfinder, was made. This shift to Sámi self-representation
Coordination is an important success factor for a development project. Communication gaps, e.g. between product owners shaping the requirements and testers verifying the developed software can result in wasted effort and unsuccessful products. We propose improving the communication between project members with recommendations of whom to interact with and what to discuss based on link prediction in
Popular Abstract in English Psychotropic pharmaceuticals include various groups of chemicals that have been designed to affect neurochemistry in human consumers resulting in changes in cognition, mood, and/or behavior; many target specific receptors and subsequently alter neurotransmitter levels in the central nervous system. The use of pharmaceuticals by consumers results in the release of these Psychotropic pharmaceuticals have been shown to exert a variety of sublethal effects on non-target organisms, even at low concentrations found in the environment (ng/L to µg/L); hence, the aim of my research has been to determine the individual-level effects of psychotropic pharmaceuticals (the selective serotonin reuptake inhibitors sertraline and fluoxetine, and the β-blocker propranolol) on beh
Experiments on a modern DI Diesel engine were carried out: The engine was fuelled with standard Diesel fuel, RME and a mixture of 85% standard Diesel fuel, 5% RME and 10% higher alcohols under low load conditions (4 bar IMEP). During these experiments, different external EGR levels were applied while the injection timing was chosen in a way to keep the location of 50% heat release constant. Emissi
