In this thesis an energy analysis of ethanol production at the ethanol plant of Lantmännen Agroetanol in Norrköping has been performed. The ethanol plant has been studied in combination with Händelöverket, the combined heat and power plant which provides the ethanol process with steam. The purpose of this study was to determine the energy consumption for the whole production chain from grain to ethanol. The analysis has included the energy consumption for cultivation of grain, production of chemicals, the production chain for wood chips, the steam production and the ethanol plant. The grain and wood chips are both considered raw materials there for the energy content in these are not included as energy input in the system.

Many perceive a boom in nostalgia and what is retro, especially within the marketing discipline. This thesis studies how nostalgia functions in the advertising context and aims to shed light on which effects there are from nostalgia evoking communication, what connections there are with other important factors as well as aspires to develop the understanding of the underlying psychological aspects and the emotional bonds to events (as nostalgia evoking stimuli in the thesis), which pave the ground for nostalgic emotions. Point of origin has been classical measures of communication effects and models of connections and causality and to these important factors have been added. Results show clear connections and correlations between nostalgia and positive communication effects, even with control for other factors that may interfere. However, the results show that some factors have moderating effects that should be important to take into consideration, namely how well the brand and the event in the ad are perceived to fit the advertising context.

The main purpose of this study was to examine how people who have felt mentally bad, describe their subjective experience of what leads to a mental well-being. The overall research questions were; how does the individual define mental well-being, how does the individual describe the turning-point during her tough period, and in what way does the individual consider that her own effort has influenced her well-being? In order to answer these questions, qualitative research interviews were conducted with persons who?ve felt mentally bad and who?ve got some kind of professional help, and who think that they have a mental well-being today. The empirical material was analyzed from a theoretical resilience perspective. The study?s result showed first of all, that there are different ways to define well-being.

There is an irregularity in the interregional migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to othermigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.

Uppsatsen är ett försök att applicera kulturvetenskaplig teori på en kontemporär subkultur. På så sätt kan den avkodas och dess kopplingar till samhällstendenser kan belysas. Tesen är att hipsterismen innehåller element som utmanar sättet vi vanligtvis tolkar och förstår ungdomskulturer på. Vidare visar forskningen att hipsterismen är ett resultat av nästan 40 år av nyliberal kapitalistisk utveckling, kombinerat med gentrifiering, konsumtionsvanor, kulturellt kapital och subkultur..

The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge.The tenant-owner?s association Duvan at Petterslundsgatan in Uppsala installed year 1999-2000 a geothermal heating system. The purpose of this installation was that they hoped it would lead to a smaller usage of district heating which would lead to a reduction of the heating expenses for their buildings. The geothermal heating system consists of 19 energy wells and 4 geothermal heat pumps, and it is one of the first systems of that size in the region of Uppsala.

In today?s IT-community, consumers use the internet in a increasing rate to find information or to purchase products and services. This has led to a growth in the market, but also a greater competition between e-stores and web shops. To separate yourself from the masses has become more important, the question is; what strategy should the IT-salesman use? The meaning of this scientific study is to find and focus on witch the primary factors/aspects are, that controls and is the very foundation for the consumer making a purchase, by using the internet.

Families with limited financial resources risk social exclusion in today?s consumption-based society, where status and identity are tied to items like clothing, gifts and activities. Limited financial resources can therefore often lead to social isolation because consumption is central to social participation, something that can rarely be prioritized in poor families. In preschool, unclear policies on extra costs can negatively affect families. The purpose of the study was to investigate how socioeconomically vulnerable families experience and are affected by the preschool and its requirements, as well as how preschool teachers work to reduce the economic gap among families in the preschool context.

Companies have in the past decades changed fromtraditional manufacturing organizations into serviceorganizations. For these service organizationsinformation and competence have become animportant resource. The traditional view oninformation is that an employee use and search forinformation to reduce uncertainty for their decisionmaking. Even though information is strategicallyimportant for organizations, information is not valuedin any way. Hence, this thesis aims to valueinformation in terms of the utility it brings to theorganization.The conclusion is that four factors are important whenvaluing information in terms of utility.

The purpose of this report was to investigate how the abiotic factors (temperature, pH, nutrients, oxygen levels and water content) would affect the decomposition of oil-contaminated soil and how a variance in structured soil would affect the decomposition-rate. A minor field-study was made and soil where structured in five different ways (one was a default pile and was used as a reference). The study took place over 137 days and three samples were taken (start, middle, end) and analyzed for aromatic and aliphatic compounds. The result of this study shows that there is a significant difference between all methods for the aliphatic compounds and no significant difference for the aromatic compounds. The abiotic factors that affect decomposition vary from organism to organism, depending on what type of environment it will function the best.

During the last few years the countries in the African continent have experienced an enormous increase in female politicians on a national level. Rwanda is even the country with the highest number of female politicians in its parliament in the world. Despite this development in Africa, the quantitative research on women's political representation in the world has not yet paid attention to the situation there. Some of the surveys that have been done have even excluded countries that do not fit the homogeneous pattern ? which is precisely the problem with African countries ? for it to be possible to explain the situation with existing theories.The intention of this paper is therefore to, with all of the 53 African countries included in the study, examine whether the already existing explanatory factors regarding women's political representation also can be applied to an African context to explain the situation there.

The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.
