In this study, a fully three-dimensional calculation method has been further developed to simulate and analyze various processes in a thick anode duct. The composite duct consists of a porous layer, the flow duct and solid current connector. The analysis takes the electrochemical reactions into account. Momentum and heat transport together with gas species equations have been solved by coupled sou

Popular Abstract in English Drizzle a thin stream of olive oil into water. The oil splashes into tiny little drops first, and in a fraction of a second, they emerge from bulk to the surface, and then coalesce to form a thin layer. This phenomenon relates to the molecular properties of the liquids. Olive oil is composed, in a large extent, of molecules with a fierce name, triglycerides, which are bSolid-state nuclear magnetic resonance (NMR) spectroscopy and molecular dynamics (MD) simulations were employed to study molecular structure and dynamics in amphiphilic bilayers. This thesis reports on method development and practical applications to two types of bilayer systems: simple cell membrane models composed of phosphatidylcholine lipids and cholesterol; and liquid crystals composed of eth

The beach topography change in the nearshore zone may be induced by natural phenomena such as wind, wave, storm, tsunami, and sea level rise. However, it can also be caused by man-made structures and activities, for example, groins, detached breakwaters, seawalls, dredging, and beach nourishment. Therefore, understanding the beach topography evolution in this zone is necessary and important for co

Most state-of-the-art natural gas fired combined cycle (NGCC) plants are triple-pressure reheat cycles with efficiencies close to 60 percent. However, with carbon capture and storage, the efficiency will be penalized by almost 10 percent units. To limit the energy consumption for a carbon capture NGCC plant, exhaust gas recirculation (EGR) is necessary. Utilizing EGR increases the CO2 content in t

Olika användningar av begreppet paradigm beskrivs: Föredömliga experiment, argumentationsstrategier, inflytelserika teorier, betydelsefulla arbeten, respektive ett system av förutsättningar eller utgångspunkter. Kuhns betydelse för den nutida användningen av begreppet paradigm markeras. Han använde det för att uttrycka en viss grad av relativism och icke-rationalitet i förståelsen av vetenskapligt

This chapter uses Critical Discourse Analysis (CDA) to conceptualise changes that have occurred in the urban development in the Swedish city of Malmö. The concepts of CDA and its philosophical foundations in Critical Realism are discussed, and linked with the methodology of dialectics. The two texts Västra Hamnen – City of Tomorrow (the Western Harbour – City of Tomorrow) and Områdesfakta för Malm

The aim of this thesis was to study the chemical communication involved in aggressive and reproductive behaviours in the European lobster (Homarus gammarus). Both male and female H. gammarus established and maintained dominance, but the sexes used different strategies for dominance maintenance. Male losers recognised individual fight opponents and avoided them but fought actively against unfamili

In this paper it is shown that the central features of systematic engineering design process models: a step-by-step concretisation of the product with a systematic variation of subsolutions and recombination are not absolutely necessary. Current models are neither generic nor ideal. Instead of using product characteristics as a basis for design process models, the focus should be on the concrete g

The Social Work Virtual Campus (SW-VirCamp) is an Internet based international pedagogical pilot project aiming at 1) developing a virtual campus for social work education; 2) developing a new e-learning module in Community Work and Community Development; 3) arranging a pilot course in the mentioned subjects. The project is financed by the EU Comission within the Lifelong learning ERASMUS program.
