The transformer is one of the most common and most important electric machines for power companies. Cost of investment and the economic worth of a transformer are counted in millions of SEK. Because of that, proper maintenance actions that may lead to longer technical life time should be the aim in all situations.The aim with the report was to perform transformer diagnosis by dissolved gas analysis on Umeå Energi AB´s power transformers and a risk assessment. The report should also contribute to longer life time for the transformers.Oil samples were taken from each transformer two times. The first sample in summer 2013 and the second in April 2014.

The purpose of this thesis is to study how swedishness is constructed and narrated in two Swedish documentary series that picture the Swedish participation in the international ISAF mission in Afghanistan. The main focus lies on how the Swedish soldier as such is portrayed, on which values, characteristics and qualities that they are said to embody and how these are linked to notions of swedishness, particularly the strong historical narrative, formed during the second half of the twentieth century, that defines Sweden as a peaceful, neutral and humanitarian state, with peaceful, enlightened and democratically minded citizens. Theoretically it draws on the concept of metanarrative to explain how ideas of shared national origin translates in to a broad organizing discourse, that defines, interprets and communicates notions of what it means to be a Swede and what is needed to make claims on swedishness. Another concept, that of national bodyscape, is also used to further define and explain how ideas of nationality are embodied and take the form of specific characteristics and  personal qualities. The meaning-making in these two series makes use of the above mentioned definition of swedishness as defined by humanitarian concerns, democratic ideals and moral superiority to construct an image of the Swedish soldiers as on the one hand soft, humanitarians, who are needed in Afghanistan because of their especially strong sense of justice and moral, and, on the other, as tough soldiers, who are able to participate in every aspect of the war as fighters.

My purpose with this essay is to examine the relationship between esthetic learning processes and language development to find good practices in my work with multilingual children. In my report, I describe a few activities from my work as a preschool pedagogue in a multicultural area, with a large group of children where age and knowledge of Swedish varies. The background to this essay is the problems I experienced in my work with children´s language development in an organization that, in my opinion, is limited by economic factors. The questions I poses are about the way esthetic learning processes can help children develop their language skills as well as their participation in preschool activities. I also pose the question whether there is a connection between the musical ear and children´s development of language.

As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.

The real estate company Ihus is facing an expansion of its comfort cooling in Noatun,Uppsala, to provide the buildings in the block with cooling. The buildings in Noatunare mainly used for office premises, where the requirements for an accepted indoorclimate is great. However, it?s uncertain whether Ihus should continue, as currently,producing comfort cooling by themselves using a compressor chiller, or if they shouldconnect themselves to Vattenfall?s district cooling net.The purpose of this report is to examine which technique of cooling is best suited forIhus and their buildings in Noatun. It should also work as a guideline for othercompanies facing the same problem as Ihus.

The purpose of this study is to generate knowledge about how teachers relate to students with language impairment in learning situations, with particular focus on working memory. The questions are: What kind of knowledge do teachers have regarding language impairment and working memory?, What experience do teachers have regarding lack of working memory abilities among students with language impairment and which consequences do the teachers believe such defects may have for the students? and How can teachers create a learning environment that reduces the working memory demand for students with language impairment? A review of the field shows that there are gaps to fill regarding students with language impairment and working memory. Language impairment has so far been neglected by researchers and within the public debate. How working memory capacity affects the students has only recently begun to receive attention in school and research.

Management control systems are a popular area of research and a lot of new research has been done over the past years. This development has been looking into new situations and circumstances, and interdisciplinary studies are being made to further understand the connection between different fields of study. A new field of study that has grown significantly over the past few years is the connection between management control systems and entrepreneurship. Leading researchers have proposed a number of questions for further research and one of them is the board of directors? use of management control systems in entrepreneurial firms.The purpose of this study was to examine the differences and similarities in the board of directors? use of management control systems between entrepreneurial and non-entrepreneurial firms.The study was conducted as a deductive qualitative study through interviews with respondents from entrepreneurial and non-entrepreneurial firms.

The purpose of this study is to illustrate if structural factors to welfare indicators and the internal organisation of handle social assistance in combination with dominating ways of living with their values and norms can be used to explain why the costs of social assistance are low in Säffle township. The character of this study is exploratory, though important aspects in this case was unknown. The empiricism come from descriptive secondary statistics and from qualitative interwievs with three inhabitants in Säffle, whom are experts which means they know the township of Säffle and it´s inhabitants well. Säffle has been studied from four perspectives, of which the first two have a top- or macroperspective. In the study appears two divergent pictures.

Nature conservation agreement (NCA) is a way to voluntarily protect and manage nature for limited time-periods. The agreement is settled between the government and a landowner. All public authorities can represent the government but it is only the Swedish Forest Administration who does that regularly (because it is the only authority with economic resources for that purpose). Therefore, NCAs are almost only used to protect forested nature. The government agencies have experienced NCAs for about ten years and it is now time to examine how they are applied in the forests. This study is based on a computerized questionnaire to the persons responsible for the LEKO-projekt.

Many traffic incidents are due to the driver?s lack of attention, resulting in dangerous lane departures, either sliding off theroad or into the oppose lane. These kinds of incidents often have serious outcomes, which has led to much effort being concentrated on preventing or lessening the damages when the incident is already a fact, for example by installing safety belts and air bags. These measures may be considered to be acts of so-called passive safety. Active safety on the other hand, means that the safety systems intervene before the incidents have occurred.

The increasing road traffic in Sweden will require investments in the infrastructure that the tax withdrawal of today will not allow according to a new government report, SOU 2006:33. An existing willingness to pay for those investments has therefore become an alternative to increases in taxation to be able to cover the costs. A proposal to let the willingness to pay, alternatively increases in taxation that act proportional, decide how a cost is distributed can be said to be related, but not fully correspond, with different theories of justice described by Robert Nozick and John Rawls. It can therefore be interesting to see how the two different theories of justice are edified and how they distribute a joint cost. The aim of the first part of the thesis is to present and criticize Rawls' and Nozick's theories of justice in a common formulated economic model.

The aim of this thesis is to examine the archivist's professional role in public authorities and discuss if, and in what way, the profession is effected by the new swedish process oriented archival description system. The study focuses on swedish authorities and does not make any international comparisons with other institutions. Neither does it investigate archivists workingin the private sector, but centers on public institutions.The survey is performed in five swedish public authorities, using interviews and observations. Grounded theory is used as a method initially in the purpose of keeping an open mark towards the object of study. The initial results led on to questions about how well the archivists perceived that communication within the authorities served, and how this in turn prepossessed their work situation and the professional roles in which they found themselves.

As the media attention society on the world climate change, interest in the environment and social impact has increased. This has in turn made even more companies choose to maintain a sustainability report that contains the three aspects of economic, environment and social impact. The demand for sustainability reports has increased among stakeholders. It has made the companies that establish this form of reports experienced economic benefits. The sustainability report than became a useful way to compete among businesses.

Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.

In the increasing urban environments and the modern societies demands for sustainability there is a challange in planning cities with a balance between density and a satisfying access of recreational environments. For attractive cities these environments need to be designed to fit every inhabitants? demands and opinions in some way. Increased knowledge and understanding is therefore needed about how different design styles in landscape architecture affect people and the cities. In this bachelor thesis benefits and disadvantages as well as the experience and impact of two fundamental design styles i discussed; naturalistic and formal/abstract design.
