The energy sector of modern time is currently faced with several challenges. These are both production oriented and environmental oriented in nature. The energy of the future is intended to support an increasing demand while at the same time reduce its environmental affection. This stresses a development towards production methods of renewable energy. Among the existing methods, biogas is presented as an attractive alternative.

Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.

Real estate financing is one of the key figures for financial success and fundamental to asuccessful business.

This report presents an independent thesis corresponding 15hp and was carried out on Högskolan in Halmstad during the spring of 2014. The thesis is the final course which ends a three-year mechanical engineering program with focus on technical design.The thesis started in an operation which electricians are exposed to every day. The operation in question is cable laying or wiring. The tool they use is called a tension spring and is a long and stiff wire, usually made out of nylon or fiberglass. The tension spring is fed through pipes in the walls and brings the desired cables with it on the way back.

Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.

The means to political participation at the local level in Sweden are changing and this change is analyzed through a case study. The first aim is to explore the forms of public political participation in Swedish municipal Älvkarleby, namely public question time in local government, citizen motions and open meetings. A part of this is also to analyze he every day contact between citizens and representatives. The second aim concerns the reasons why politicians decide to support these means to participationThe empirical material consists mainly of semi structured interviews with local politicians, civil servants, participating citizens and local press. Official documents such as public minutes are also used in the process of creating an image of local participation.Local political participation is found to be limited but yet having the potential to strengthen democracy, provided that public decision-makers are open to a dialogue with the participants.Using Kjell Arne Røvik's theories of organisational change, the changes in local democracy can be explained as being partly rational, partly symbolic and partly identity shaping political decisions..

Lundbergs Plåt AB is a small company situated in Jönköping. Their main task is to process different kinds of steel such as stainless steel. Lately, they have shown an interest in Lean production.On the basis of the situation mentioned above, we developed the purpose to find and decrease the non value-added wastes in the production at Lundbergs Plåt AB. Out of this, we also developed and answered two questions: Which wastes can be found with help from a value stream mapping (VSM)? In what way can these wastes be reduced and how can these reductions contribute to an improved production? VSM is the method used to find the non value-added wastes.

The purpose of this master?s thesis is to investigate children?s access to specific children?s activities at Swedish public libraries 2005. The thesis is based on literature studies and qualitative interviews with children?s librarians, library directors and local politicians at two demographically different libraries in Gothenburg.The sub questions are: What measures exist to promote children?s access to public libraries and children?s activities when it comes to: law and other political statements: different efforts on the state level and different efforts on the municipal level in the direct activity with children at public libraries? What driving forces and needs justify activities for children at public libraries? How will the responsible persons judge that the efforts are sufficient? The result of the study shows that children?s access to library activity has increased in the last couple of years due to reorganization, economic savings with closing down of library affiliates and because libraries have given priority to other things, like IT and new media. Children?s librarians have got new assignments and less time for children?s activity.The conclusion of our investigation is that children?s librarians are ambitious in their work, but unfortunately don?t give children?s library activity adequate resources.

Climate change and the sea level rise that it contributes to is an ever more pressing issue for costal municipalities around the world. Today there is a great deal of scientific reports and projections on what these changes could entail. However, resent studies on south Swedish costal municipalities have shown great discrepancies when it comes to how these scientific projections are implemented in the municipal planning and adaptation strategies. In an effort to understand the underlying reasons for this lack of concurrence, this paper has applied Rolf Lidskogs theory of the hetrogenity of science. The theory gives an explanation to the complications in the science-policy interface, by describing complicating factors in the communication between these actors.

This article starts with a review of the literature regarding the normal reproductive physiology of the mare, normal luteolysis, different causes of prolonged luteal phase and theories behind these. The article also presents a study where it was examined if treatment with human choriongonadotropic hormone (hCG) during the luteal phase induces prolonged luteal phase in mares, thus preventing estrus. The study consisted of two parts: one intensive study of eight mares at the former Department of Obstetrics and Gynaecology at SLU, Uppsala, Sweden and one field study of seven mares at a stud farm 70 km north of Uppsala. The mares in the intensive study were divided in two groups: one with four mares that were injected with hCG in luteal phase when they had a follicle of minimum 30 mm and a second group with four mares that were injected with sodium chloride at the same time. These mares were examined with ultrasonography and blood samples.

This essay deals with Swedish unemployment politics during the period 1918-1932, and can be seen as a contribution to earlier research of how the policies, established by the State Unemployment Commission, was carried out at a local level. This study bears upon  Uddevalla municipality, a town in the southwestern part of Sweden, which had about 13,700 inhabitants in 1920.The research was conducted in Uddevalla municipality archives, and the sources used are above all municipal records and documents from the local unemployment committee. The measures taken by the local committee to reduce the effects of unemployment have then been compared with the directives of the State Unemployment Commission.The survey shows that the local unemployment committee, at least during the first half of the 1920s, was very keen to follow the directives of the State Unemployment Commission, and they also tried to charge the municipality's economy as little as possible. The local policy was often even more restrictive than the demands from the State Unemployment Commission. During a few years in the middle of the 1920s, when the unemployment was relatively low, most of the unemployed did not recieve any help at all.The restrictive policy, however, led to an increasing distress among the unemployed, and the poor relief had to give financial help to a lot of unemployed and their families.

Malmö, like many other bigger cities in Europe, faces a double undertaking when facing the challenges the future. Not only must the municipal be able to provide its citizens with welfare and a high standard of living, it must also establish a level of economic growth that allows the city to act as catalyst for the surrounding area. In order to provide the population with welfare and the economy with a qualified working force, these two challenges have been combined into one plan for the future called Welfare for Everybody. As part of this plan, new organisations have been created with the purpose collaborating with the social services office and support people in their transaction from welfare recipients to self-providing workers. The purpose of our thesis is to build on Michael Lipsky's classic work "Street-level Bureaucracy" and by conducting interviews with a number of front line workers study how they view their role, the client group and how they motivate the working line.
