A growing interest for the climate and the environment has led to an increased interest forenvironmentally friendly and renewable energy sources, such as biogas. Planning new biogasplants requires a decision basis including facts about approximate amounts of biogas possibleto produce at the plant. The purpose of this thesis is to develop a model that calculates theapproximate biogas and digestate production from a planned or existing biogas plant.Developing the model required a literature review and studies of calculations concerningbiogas and digestate production performed by WSP Sweden AB. As a complement to themodel development, facts about substrates for biogas production were compiled through aliterature review. In addition the methane potential from selected materials was determined bybatch experiments.

This report describes a study aimed at uncovering flaws and finding potential improvements from when the modelling tool EAAT is used in conjunction with the modelling language CySeMoL. The study was performed by developing a framework and applying it on CySeMoL and EAAT in real life context networks.The framework was developed in order to increase the number of flaws uncovered as well as gather potential improvements to both EAAT and CySeMoL. The basis of the framework is a modified version of the Quality in use model from ISO/IEC 25010:2011 standard. Upon the characteristics and sub characteristics of this modified model different values for measuring usability where attached. The purpose of these values is to measure usability from the perspectives of both creating and interpreting models.

The purpose of this thesis is to research public librarians view ofthe public library as a meeting place and how it may contribute tofacilitate social integration. To study this we have asked thefollowing research questions: How do public librarians work withthe public library as a meeting place? And how do they contributeconditions for ?soft inclusion??The method we have used for this study is semi-structuredinterviews. Seven public librarians from the Gothenburg areawere interviewed and the empirical material was analyzed usingqualitative content analysis.As a theoretical foundation we have used Dorte Skot-Hansensmodel of the public library as a third place and Mikael Stigendalstheory on social inclusion. Furthermore have we used research onthe public library as a meeting place and social integration as acomplement to the model and the theory.Conclusions from the material gathered is that public librarianssee the public library as a meeting place with potential tocontribute to integrating individuals and groups with one another.The librarians? foremost method was to attract visitors withactivities aimed at certain target groups.

The Swedish public inquiries and most of the political science advocate reforms in the spirit of participatory democracy to strengthen the democracy. Although it is striking how limited and narrow the scientific documentation is in analysing the effects of participatory democratic reforms. Still, many of the local governments in Sweden are reshaping their organisations according to the participatory democracy model. Is it a trend and a symbolic action or a veritable action of good-will of the politicians?The paper argues that the idea of participatory democracy has become popular and widely spread.

In 2010, SAS received the "On time performance service" award by Flightstats. This award was an affirmation of long-term work, both in projects and as an ongoing process, which the company sought to systematically improve punctuality on its flights. The extent to which SAS followed the values and the underlying theories of the cornerstone model for total quality management was the main issue in this essay. Whether there are conditions for the company to get even further by working in other ways was also investigated. In addition, the importance of punctuality in relation to customer satisfaction was discussed.

Social media provides, as many points out, new possibilities for marketing. Marketing in social media requires a two way communication, rather than the traditional marketing where the communication model is typically sender ? receiver.To create a marketing campaign that is suitable for a two way communication model has its difficulties and risks as well as its opportunities. Opportunities in the sense that the campaign can become a viral, a Word of mouth and create a Buzz, which will reach potential customers, to a bigger quantity for lower costs, with a message that will make a different impact from the types of commercial messages we are used to. Risks in the sense that the message, if not properly aimed and phrased, can be turned overnight into something that humiliates the company and possibly harm its brand.The difficulties in creating such a campaign is to create something that will catch people?s attention, discuss and forward it, while at the same time avoid getting hurt.We aim to describe the internet from a cultural context, and from that point of view explore the types of misunderstandings which often seem to happen when a corporate message is created and sent out in social media, how to avoid putting the image of a company in danger when doing this, and examine if there is ways to know how the message will be received.

Purpose: To investigate if Altman´s Z´-score model, which calculates financial distress, can be applied on companies established in Sweden and if the financial crisis in 2008 made previously healthy companies go bankrupt.Methodology: Quantitative studies with a positivistic foundation. Empirical data will be collected in order to examine if there is generalizability among the studied objects. Conclusions will be made by comparing the empirical data with the theoretical foundation. Financial distress in firms will be measured.Theoretical perspectives: Altman´s Z´-score model, designed to predict financial distress in private firms.Empirical foundation: A selection of 93 private firms that have gone bankrupt in the years 2008, 2009 or 2010. The firms selected all have a turnover that exceeds 20 million SEK.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

With this paper my aim has been to investigate my subjectivity and responsibility as a landscape architect and to find ways to relate to it and handle it in my work. When I advocate a certain concept for a project, I influence the outcome, and in doing so I take on a personal responsibility. Even though my judgement is built upon facts and cooperation with colleagues and other consultants, I am always responsible for the part I play and how I affect the course of action. To what extent can I advocate my view and is it actually my responsibility to do it? How is my subjectivity part of my knowledge and influence as a landscape architect? I have interviewed three well known Swedish landscape architects to have their view on the matter. Since they are all strong individuals with huge experience and influence, the personal responsibility they bring upon themselves for their design action is as important. I have also used one of my own projects as a case study, analysing my design and standpoint and my relationship to the client to illustrate how these questions emerge even in the smallest projects. In the last section of the investigation I have searched for clues in diverse literature. This section is divided into three view points; the society, the profession and the individual..

The aim of this Master?s thesis is to investigate and increase the understanding of Swedish Public Library Websites and to determinate which activity they mediate. To analyse the Public Library Websites Andersson and Skot-Hansen?s model of roles for the Public Library has been used. This model in¬cludes four roles for the library: the library as a cultural centre, a knowledge centre, as an information centre and as a social centre.

This paper analyses how Swedish fine-art oil paintings sold at auctions has performed as a monetary investment during the period autumn 1985 until spring 2006. An average price technique as well as a hedonic regression technique, applied to a sample of 19 213 auction sales, is used to construct price indices. The indices show somewhat different results, which is explained by the inability of the average price model to adjust for relative differences in quality between periods. The hedonic regression model on the other hand captures this effect, why the hedonic index is applied in a financial return model. By adjusting for transaction cost, the financial return of an average investment in paintings is calculated.

The first of the dual purposes of this work has been to describe the research that has been done regarding the root causes of terrorism and second, using a general causal theory and examining the political dimensions of it, to discuss whether or not general causal theories (grand-theories) are helpful for researchers and policy-makers when reacting to social developments in the form of terrorism. The essay is a qualitative literature analysis and I have based my studies on mostly new books treating root causes of terrorism. I have concentrated on discussing international terrorism and how political dimensions may impact the occurence of this form of political violence. The conclusions I have made is that there is no widespread consensus among researchers and scholars as to what really causes terrorism. Neither can the general model examined in chapter 5 be used to predict when and where terrorism will occur next.

Introduction The genetic skin disease epidermolytic ichtyosis is caused by mutations in either keratin gene 1 or 10 and leads to blisters and hyperkeratosis of the epidermis. At cellular level the disease is seen as aggregates in the keratin filaments. Since medicines are hard to investigate and produce mainly due to lack of reproducible model systems, there is no good treatment available for this disease today. In this article we describe how an in vitro model consisting of cells from a stable cell line transfected with expression plasmids to mimic patient cells, may be a possible alternative for screening compounds for therapies. The first step was to generate an expression plasmid required to complete the in vitro model.

The aim of this Master's thesis is to study what place public libraries have in local politics, particularly from the point of view of the politicians. To answer this, I have interviewed politicians, participated as a silent observer of a public debate, and studied articles on library politics in newspapers and other press. The results show that politicians in general have a positive view of libraries and good co-operation with library professionals, and that they have a fairly up-to-date view of libraries. They are, however, less interested in library issues in general, and are often complacent with the way things are already running. The newspaper studies show that library issues are usually only discussed when a specific library is somehow in danger.
