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.

Since the disintegration of the Soviet Union a lot of hope has been put on civil society to help develop Russia into a more democratic society. This study explores the constructive elements in the relationship between civil society and the state in Russia, and how this enables the work toward political development. By using Julie Fishers theory about political development and organisational autonomy I discuss the varying and often complex ways in which civil society and the state interacts. These are often not mentioned in the liberal tradition, which believes that civil society's most important democratic function is to act as a watchdog for the state.There is very limited political space for NGO's in authoritative Russia. The existing oppositional NGO's are important for the political development, but they are few and their impacts on society are limited.

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 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.

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.

Social enterprises make up one of the groups of participants that provide welfare services financed by public funding. The object of this study is to describe and analyze from a theoretical point of view which conditions, in what fields, by which division of responsibility and finally through what decisions these social enterprises are allocated a place in the market for social welfare services. The company that has been the object of study offers services in the field of social welfare and in employment. In the study a triangulation of qualitative methods has been used: studies of literature on the subject, recurrent interviews and observations and also reviews of documents. The results have been analyzed from theories on the space available on the market for social services, on social economy and on social capital in the form of strong, weak and bridging bonds.

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.

This Master Thesis treats the non monetarian aspect about the Internet Portal from a consumer and company perspective. The purpose of this thesis i st o give or create a picture and a tool, a model for how the Internetportal could be evaluated an valued. By creating a so called Dynamic Scorecard the authors of this Thesis have created a model throug which the purpose of this thesis is served. Through this model the authors have come to the conclusion that the Internet Portal can be evaluated through both economic, social, service and technical factors as well as through what relationship the companies or consumers value concerning the Internet provider. The product of conclusions of this Thesis is that there are three main factors upon wich the Internet Portal is valued.

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.

Stump wood is a hot alternative when the heating plants demands more and more forest fuel. The aim with the study has bean to calculate the costs in four different systems for transportations of stump wood, examine if there are any differences in fuel quality for the stump wood in the different systems, analyse if the fuel quality in stump wood is affected with the time it lays by the road side and how much space the stump wood demands on the road side. To calculate the costs for the different systems a system analysis was carried out, where some of the costs were collected through field studies on Holmen Skog stump experiment and other costs were collected from literature and contacts. Data for the fuel quality study was collected from Eons heat plant in Norrköping. Data for the study of how much space stump wood takes along a roadside was collected from field studies.
