In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.

Rådet för kommunal redovisning utkom 2006 och 2009 med nya rekommendationer för hur kommuner ska värdera sina anläggningstillgångars nyttjandetider. Syftet med detta arbete är att öka förståelsen för hur kommuner värderar och fastställer materiella tillgångars nyttjandetider. Arbetet syftar till att identifiera och beskriva kommuners värderingsmetoder, arbetsprocesser samt att utveckla en modell för fastställande av tillgångars nyttjandetider. Arbetets data är insamlad genom två delstudier där semistrukturerade intervjuer användes som datainsamlingsmetod. Insamlad data analyserades med hjälp av teorin om ansvarsskyldighet, agentteorin, teorin om förvaltarskap, institutionell teori samt Life cycle costing teorin.

AbstractThe aim of the thesis was to examine some older people's experiences of everyday life and how it is to grow old in Namibia today. Because everyday life is a broad concept, we chose to focus on some specific parts of everyday life. These are chores, family, work/education, elderly past and present and the government/society. Furthermore we chose to look at the similarities and differences between the experiences on the basis of gender, race/ethnic groups and class.We chose to use a qualitative research method and to be inspired by life stories. We used a semi-structured interview guide and interviewed six people between 70 and 89 years.

The conversion in the Viking Age and the High Middle Agea in Scandinavia and how this affected women is discussed. Did women get a better life when the people had converted to Christianity or not. Our written sources are later than the conversion to Christianity. Instead the material culture, graves, grave goods and runic stones, can help us understand the life of women. Nordic mythology presents a contrast between faith in the Viking Age and Christianity..

In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated.  This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.

The aim of this study was to investigate factors that ex-criminals believe have been of importance to them when they decided to leave a lifestyle of criminality behind. The study was based on eight semi-structured interviews with informants who had committed various forms of crime. Common to all informants is that they are now members in the Swedish association KRIS (In English: CRIS, Criminals Return Into Society), living a life without crime. The stories of the informants have been analyzed on the theoretical basis of social ties, the exit process, role loss, motivation and the life course perspective. Our study showed that the informants have been affected and motivated by various life events that could be identified and pin-pointed during the interviews.

The purpose of this study is to examine how EU-migrants visiting the social project Crossroads experience their life situation in the Swedish society. Two questions were formulated: (1) How do the respondents describe their situation when it comes to work, housing and social network? (2) How do the interviewees describe and experience the social project Crossroads? The method used was qualitative interviews conducted with five EU-migrants who visited Crossroads. The theoretical framework is the concept of integration and Bauböcks (1996) theoretical model of the ideal society. The results show that none of the interviewees had their own accommodation.

Social support is important for adults well-being, quality of life and self-esteem. The nurse should respond to the patient's care needs, knowledge of social support for young people with chronic diseases is therefore important. The purpose was to investigate who or which ones provide social support for young people with chronic diseases and what social support contributes to. A descriptiv design where used. The literature search in the database Medline via Cinahl resulted in twelwe articles.

The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.

Silviculture in young stands in Sweden is below the mark concerning what has to be done in the forest, and it is time to solve the problem. The problem will not be solved only by the private forest owners, professional help is needed. Skogsägarna Mellanskog is one of four forest unions in Sweden who wants to play a role and take responsibility for forestry in the middle of Sweden. This academic essay is based on a market survey sent to 350 forest owners in the Örebro district. 186 of them answered the questions, giving a response frequence of 53 percentage. The purpose of the essay is to find the determining factors which will make a forest owner to find a collaborator when planning and carrying out the silviculture measures in young stands. The result of the survey shows that the forest owners are anxious about the price and the costs. The costs have a severe effect if the silviculture measures in young stands will be carried out or not.

The purpose of this study was to describe experiences in daily social life of parents of children with psychotic illness. Five parents with long-term experience of psychotic illness have been interviewed. The frame of reference in emotion theories of Thomas Scheff and Randall Collins have been used to analyze the results. The study is qualitative and has a phenomenological approach to shed lights of meanings in daily social life. The following meanings was found: Openness with certain reservation shows that honesty is important for the feeling of solidarity, Social expectations in daily life describes the parents´own expectations as well as expectations from others.

This essay addresses the issue of stress by income earners in Sweden 18-64 years old and any possible relationship to their social ties and the individualization process. The data were collected through a questionnaire, sent out to about 185 working men and women. The results showed a relationship between fewer social ties in everyday life and perceived stress of the individual. The result also showed a relationship between higher degree of individualization and stress. Both of these correlations is confirmed by previous research on the concept of work-life and theory of the new individualism.One of the most interesting results the study showed was that there was none relationship with gender and perceived stress in the individual.

In Sweden there are currently two separate guidelines you may use whenperforming calculations on frameworks, BKR and the Eurocodes. Although at theend of 2010 you are not allowed to use BKR any longer and only the Eurocodeswill be viable. The aim of this thesis is to explain how the Eurocodes and EKS work and alsohow they compare to the current guideline BKR. Similarities and differencesbetween these guidelines are also discussed so that the reader will get a betterunderstanding of how the Eurocodes are applied. The areas discussed are asfollows:Principles and adviceSafety ClassesSymbols and IndexesLifespanLoads and partial coefficientThe thesis also deals with the impact that this transition into a new guideline willhave on corporations, guideline costs, education and computer software. As anexample a rough estimate on what costs this transition will create on a companywith 20 employees is also included. Calculations have been performed in order to investigate how the design valuesdiffer between the two guidelines, the Eurocodes and BKR.

In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting. The main purpose of this study was to present two functional and energy efficient lighting systems including control system. The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.

Today, maintenance is a big part of the daily life on board ships. It is also one of the bigger expenses a shipping company has and without any loss of quality tries to run as economically advantageous as possible. In the hunt for economical savings the shore-based industry has subsequently applied the use of condition based maintenance, CBM, were a component is maintained according to its actual state. This leads to a reduction of maintenance costs since no parts are unnecessarily replaced. However, within the maritime sector a periodical maintenance is still the most commonly used maintenance system.The purpose of this paper is to chart the factors that are the reason for the low implementation of CBM on board the Swedish merchant fleet's ships.
