Ethanol from bio-products has become an important fuel for future power production. However, the present production technology is rather expensive. This paper focuses on how to lower the production cost of ethanol extraction from mash, and to use the ethanol as a primary fuel in gas turbines for heat and power production. Today, ethanol is produced during distillation by supplying energy to extrac

The European Union has initiated a number of initiatives to improve resource efficiency in Europe. The Ecodesign Directive is one of the policy instruments that could aid the transition towards a more resource efficient economy. So far, the Directive has mainly been applied to set requirements related to energy efficiency, but there is potential for setting legal standards that increase product du
Popular Abstract in Swedish I följande arbete har ett dynamiskt modellbibliotek av komponenter utvecklats för processlinjer. Analysen inriktades mot karakteristiska aspekter för processlinjer för flytande livsmedel, och nya modeller utvecklades för byte av fluidum, dispersion, blandfaser och första ordningens kemiska reaktioner i rör och värmeväxlare. Modellernas beräkningseffektivitet och noggranIn the present work a dynamic model library of components for process lines was developed. The analysis addressed characteristic aspects of liquid food process lines, and new models were developed for fluid transitions, dispersion, mixing zones and first-order chemical reactions in pipes and heat exchangers. The computational efficiency and accuracy of the models were analysed. It was demonstrated
Modern adaptive techniques in two-point boundary value problems generate the mesh by constructing a function that maps a uniform grid to the desired nonuniform grid. This paper describes a new control algorithm for constructing a grid density function $phi(x)$, such that the local mesh width $Delta x_{j+1/2}=x_{j+1}-x_j$ is computed as $Delta x_{j+1/2} = varepsilon_N / varphi_{j+1/2}$. Here $varep
Popular Abstract in Swedish Studien behandlar den sydsvenske bonadsmålaren Johannes Nilssons måleri. Denne produktive målare levde och verkade i Breareds socken i södra Halland 17571827. En analys av hans bonader visar att han i många stycken frångick sina föregångares traditionella, imiterande framställning och begränsade motivkrets. Den övergripande frågan i avhandlingen är: varför målade JohanThe aim of this dissertation is to find relationships between folk art, an artist's personal life and influential factors originating in the context. Christmas wall hangings by the peasant painter Johannes Nilsson (17571827) are the focus of the study. The fact that he had a special approach to the painting tradition raises two questions: Why did he paint the way he did? How can his hangings be i
Popular Abstract in Swedish Det svenska samhället har som många andra europeiska länder blivit mångkulturellt pga en ökande internationell migration. Behovet av information om hur detta kan inverka på hälsan bland personer med kroniska sjukdomar, som t ex diabetes, har därmed ökat. Nästan 11% av landets befolkning är idag födda utomlands. Mer än 120 olika nationaliteter finns representerade, även To study the influence of migration on health in migrant diabetic subjects, foreign-and Swedish-born persons were compared as regards objective and subjectively perceived health in relation to social position, and beliefs about health and illness and their influence on self-care and care-seeking behaviour. Persons (foreign- and Swedish-born) with known diabetes mellitus (DM), aged 16-74 years, wer
Three-dimensional mapping of atmospheric atomic mercury has been performed with lidar techniques, to our knowledge, for the first time. Industrial pollution monitoring, as well as measurements of background concentrations, is reported. High-efficiency frequency doubling of narrowband pulsed dye laser radiation was employed to generate intense radiation at the mercury UV resonance line. Field measu
This thesis is about the formation of complexes in solutions of oppositely charged polyions. We consider mainly three topics: 1)Monte Carlo simulations of oppositely charged polyelectrolytes with a focus on cluster compositions. To explain the distribution of cluster compositions, we found a minimum set of rules describing the interplay between the energy and entropy. 2)An analytical theory. The
The total transmission bandwidth and component carrier aggregation proposed by LTE-Advanced, sets a new challenge to the design of terminals. This article presents a way to assure terminals cope with the large bandwidth in an efficient manner. Various filtering methods are explored showing that an SDR architecture, such as ADRES (Architecture for Dynamically Reconfigurable Embedded Systems), is su
Religion can motivate people to altruistic activity in the service of mankind. But it can also instigate terror attacks. When does religion become senseless? Several chapters are devoted to a discussion of Buddhism and its contribution to well-being. In a final chapter the author presents his ideas about global spirituality. Representatives of the five great world religions come together in order
The purpose of this paper is to discuss the find of a Byzantine solidus in Guleboda, Älmeboda parish, southern Småland. This coin was found in an area that has never been central in any respect, and where at first sight there hardly seems to have been any Iron Age settlement at all. The purpose of the article is to try to contextualize the find. Other finds from the same site are discussed as well
