Macro- and microphase separation of compatibilizing graft copolymers in melt-mixed polystyrene/polyamide-6 blends was studied by transmission electron microscopy and thermal analysis. Three different graft copolymers with main chains of polystyrene and side chains of poly(ethylene oxide) were used as additives at various concentrations. The polyamide-6 domain sizes decreased with increasing amount
Greater wax moths (Galleria mellonella L., Pyraloidea) use ultrasound sensitive ears to detect clicking conspecifics and echolocating bats. Pyralid ears have four sensory cells, A14. The audiogram of G. mellonella has best frequency at 60 kHz with a threshold around 47 dB sound pressure level. A1 and A2 have almost equal thresholds in contrast to noctuids and geometrids. A3 responds at + 12 to + 1
The silicon vacancy in its neutral charge state (V-Si) has been unambiguously identified in 4H- and 6H-SiC. This was achieved by observation of ligand hyperfine interaction with the four carbon atoms in the nearest-neighbor shell and the twelve silicon atoms in the next-nearest-neighbor shell surrounding the vacancy. The complete hyperfine tensors have been determined for the V-Si(0) center residi
The cycle of waterborne methylmercury (meHg) in Little Rock Lake is characterized by a period of accumulation during summertime (when the lake is warm and open to the atmosphere) and a period of decline during winter (when the lake is scaled by ice). We followed this cycle for 16 yr. during which time the lake was acidified with H,SO., and then allowed to recover naturally as part of a long-term f
The circumstances and constraints under which a problem is solved can affect how people engage in problem solving. Based on that premise this research investigates the effects of motivational music in the context of a dynamic ball-transportation task. In particular, this study explores how music influences distance moved, throwing accuracy, non-linearity, motivation and emotion regulation. 15 part
The integration of environmental, social, and governance (ESG) factors in investment decisions and corporate practices has gained momentum, reflecting the global focus on sustainability and ethical practices. This study investigates the relationship between ESG-scores and stock returns from 2019 to 2022 across three industry groups – manufacturing and raw materials, technology and media services,
This study examines how descriptive, predictive, and prescriptive analytics are applied in decision-making during stable operations and disruptive events, focusing on the Swedish food retail sector during the Covid-19 pandemic. Using a qualitative case study approach with semi-structured interviews and pattern-matching analysis, the research reveals key differences in analytics usage. During stabl
The thesis examines the impact of the Trump and Biden administrations on international trade relations and agreements, specifically comparing their trade policies. It explores how their contrasting approaches—Trump's protectionist stance versus Biden's multilateral cooperation—have influenced global trade dynamics through a mixed-methods approach for analysis. The research incorporates bot
Over the last few years there has been a buzz circling one word: immersive. This word is not only connected to communication technologies, but it is also a way to explain what to expect when entering for example an art exhibition. Within the world of immersive experiences are visitors meant to watch digitised art – which is reconstructed from existing artwork – in a new and engaging way. Through c
This thesis investigates the transition of Quantum Chromodynamic (QCD) matter to a strongly interacting Quark Gluon Plasma (QGP), where quarks and gluons become deconfined. The expansion of this plasma exhibits characteristics of an ideal relativistic hydrodynamics system, suggesting a behavior similar to that of a perfect fluid. Collective behavior, indicating a QGP phase, is studied through anis
Energy efficiency in buildings can be understood elaborately by evaluating its operational and embodied energy. Embodied energy is the sum of all the energy that is used to produce materials in a building construction. This study assesses various building parameters e.g. U-value of the materials, Window to Floor Area Ratio (WFR), location, etc. that affect the operational and embodied energy and u
Climate change is escalating. In the search for alternatives to fossil fuels, many countries are pushing green hydrogen as an energy vector. The development of a hydrogen economy is planned, and social and ecological consequences are at risk of being neglected. Namibia has excellent conditions for renewables and plans to be a major exporter of green hydrogen. Germany is set to import green hydroge
The current Japanese population of 124 million is expected to decrease to 104 million by year 2050 (Takahashi et al., 2003) with a rapid aging population and, thus increasing immigration is one of the responses to this demographic concern. Hereon onwards, it will be relevant to understand the social patterns of foreign residents living in Japan and finding out more about their livelihoods as non-n
The aim of this work was to test if WebAssembly universal byte code and 5G communication technology is suitable in the context of offloading control mission of real-time systems. To test these tools a new dynamic offloading framework was implemented and tested on a Furuta pendulum, an inherently unstable and time-critical process using, among other computing units, an edge node as the offloading t
Bjärsjöholm is an estate located close to the coastal town of Ystad, around 4.5 km. The aim of this thesis was to gain insight into the changes and development that the change from Danish to Swedish rule of Scania meant for Bjärsjöholm estate. The research questions were: • How has the economy changed during the 16th, 17th and 18th century for the Bjärsjöholm estate? • What changes of the buildi
Models of the bilingual mental lexicon, such as the Revised Hierarchical Model (RHM) and the Modified Hierarchical Model (MHM), suggest an asymmetrical pattern in the mental lexicons among bilinguals between two languages, and the representations are multi-dimensional. This study sets out to understand how bilinguals process the mental lexicon of two languages for abstract words and corresponding
