Wastewater treatment is increasingly controlled by the Swedish environmental quality objectives, adopted by the Swedish parliament. There is a need for a sewage system that can fulfill stringent requirements concerning the environment, recycling and resource use and hygiene. Additional environmental aspects in recent years are the impact of climate change, new knowledge about the effects of pharmaceuticals in water, the need for improved wastewater treatment and increased recycling of nutrients to agriculture. This report has, from a future scenario of the year 2050, analyzed seven different systems for wastewater treatment and treatment of compostable biowaste from households in Eskilstuna. A future scenario was chosen based on that within a forty year period new challenges may arise which can result in higher demands on sewage treatment than those we see today. Another reason why the future scenario was established is that changes in wastewater treatment systems are slow to establish. The analysis is mainly focused on the economical aspects but environmental aspects such as emissions to receiving waters and potential recycling of plant nutrients has also been evaluated briefly.

The main purpose of this Master?s thesis is to investigate how the transfer from academic studies into professional life is experienced in retrospect by professional librarians. The aim is also to examine in which context the studies in library- and information science in Sweden has been formed. To attain the purpose of the thesis four main questions is being asked: In which context has LIS-studies from the period 1993-2007 been formed? Which competence does the professional librarian consider to be the most fundamental in professional life? Does the professional librarian experience that the knowledge attained from LIS-studies is sufficient for the actual tasks? Which are the differences between tasks at different types of libraries? The study is performed through a questionnaire survey in which 94 professional librarians express their experiences of their LIS-studies in retrospect.

AimThe aim of the study is to examine how future teachers of Physical Education view the subject, the occupation and their attitudes about the future and create an understanding about this through these research questions:In what way do the teacher students justify the subject Physical Education?How do teacher students view the future of the subject and the occupation?According to the teacher students, what and whom affect the subject? Is there a difference between the teacher students?views and attitudes depending on if they are currently in their second or last year of their education?MethodThis study use qualitative methods in order to create a deeper understanding for the participants? views and attitudes. Eight teacher students of Physical Education were interviewed. The interviews were between 27-57 minutes. They were recorded, transcribed and then analyzed from a socio-cultural perspective as well as Bernstein?s theory of classification.ResultThe participants justify the subject in words such as that it gives the students? knowledge about how to uphold a decent standard of living and an understanding for the correlation between physical activity, nutrition, health and wellbeing.

The purpose of this thesis is to shine some light on how B2C companies in Sweden carry out a viral marketing campaign. Through case studies of two comparably sized companies, Arla and If Skadeförsäkringar, this was examined. This study shows that viral marketing is still a new subject for both marketers and researchers. It is hard to find conclusive methods for how to carry out such a marketing campaign successfully leaving companies feeling that they first have to go through a trial and error process. This is evident in this case study, where viral marketing is degraded to a tool for generating awareness rather than producing actual results as part of a holistic marketing plan and where those results are too uncertain to rely on.

The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.

Background: Sweden is a country where vitamin D deficiency seems to be common, partly because of its geographical position, which reduces the availability of UVB radiation, but also that people avoid sunlight due to increased skin cancer risk. Research shows that vitamin D plays an important role in the prevention of many diseases such as cancer as well as autoimmune and neuropsychiatric diseases.Vitamin D is a fat soluble pre-hormone and a collective name for closely related compounds which act as hormones after undergoing a transformation in the body.Humans can utilize vitamin D through diet and produce it in the body by exposing the skin to the sun. Previous observational studies and epidemiological studies have established a hypothesis that there seems to be an association between vitamin D supplementation and reduction of depressive symptoms.Objective: The aim of this study was to investigate if vitamin D supplements may decrease depressive symptoms.Methods: This work is organized as a literature review and article search is made in the database PubMed in January 2012. Keywords used were ?vitamin D and depression? and inclusion criteria were: randomized clinical trials, be conducted on humans, written in English.

This essay is about the use of narrative in video games, and the discussion surrounding it. For years ludologists (game researchers) and narratologists (narrativity researchers) have been arguing about how to analyze narrativity in games. While ludologists have chosen to see games as a product by itself, and therefore something to be analyzed separately, narratologists instead see games as a narrative medium alongside film, theater and books. This essay starts by taking a look at the arguments from both sides, and then introduces three questions regarding narrative in games, and how this phenomenon has changed over the past 13 years. To answer these questions, five case studies are carried out, analyzing games with the help of a new framework built on narrative theory.

Where is technology heading? And how will our behaviors towards these new innovations look? This project questions the direction of ?beyond smart? products, through scenarios within our everyday life. The work is both critical and speculative. Speculative in the sense that it is speculating in how a future scenario with ?beyond smart? products would look like.

The purpose of this thesis is to assist the Swedish energy company NIBE Energy Systems in their studies of adaptive regulation applicable to electrical water heaters. Due to coming energy classifications of these appliances in the European Union, NIBE Energy Systems needs to use adaptive regulation, called Smart Control, to keep their products in the best possible energy class and remain competitive to the market. By using this Smart Control regulation a 2-3 % improve-ment of efficiency can be credited the system. This is a small number, but heavily needed, since the energy classes are based on the idea that the European Union is provided with electricity from coal condensate power resulting in a 40 % maximum efficiency. Furthermore, doing noth-ing will result in some water heaters not being approved to use on the market from 2015 due to low efficiency.

The main purpose of this examination paper has been to do a review of recent scientific and evaluated studies performed on children 0-15 years of age, treated with an animal as an assistant to the therapist/professional. The key term is Animal Assisted Therapy (AAT). Our focus has been to describe in what fields these kinds of studies have been performed, what the results are and how effective they have been. As a supplement to our study we have performed 8 short telephone interviews with professionals in the same field of occupation corresponding to the studies we have summarized. Our results concerning the studies show that there has been a positive outcome in the treatment of children and adolescents and AAT.

The first of May 2007, a decision from the Swedish Board of Fisheries about a Swedish prohibition of eel fishery got legal force. This prohibition is one of the most challenged decisions that the Swedish Board of Fisheries has taken. In the town Karlskrona in the southeastern part of Sweden the prohibition has got a lot of attention in local media. Early in the debate, it was clear that the actors active in the archipelago of Karlskrona were against the prohibition. The aim with the master thesis is to investigate different actors' opinions and view of the prohibition of eel fishery, today's management of the resource and how the actors' think that the communication between the actors involved in the management of eel and eel fishery works and what need to be changed to be able to develop a sustainable management of the eel in the future.

Abstract Cavities used to be a very common problem but over time humans have learned to take care of their teeth. However, there are still many who have problems. This problem is due to microorganisms and in particular the various streptococci and lactobacilli producing acids which loosens up the enamel on teeth. These bacteria can be found at various places in the mouth and saliva. Besides being a discomfort it can be a major problems and the damaged tooth needs to be removed or make a dental filling. The aim of the study was to see how intake of probiotic tablets containing Lactobacillus reuteri PTA ATCC 5289 and Lactobacillus reuteri DSM 17938 affects the levels of oral Streptococcus mutans and lactobacilli over a three-week period.

Volvo Penta has been producing boat engines since 1907 and are world leading in this seg­ment. They have today an extended range and also sell industrial power stations. Quality, safe­ty and environmental care are three core values for Volvo and together they strive to give their customers the right product with the right quality.Volvo has developed a production system named Volvo Production System, VPS, and one of the pillars is continuous improvements. Within this pillar you can find value stream map­ping, which is used to analyze the value stream through the process. This tool gives a wide perspective and helps to keep focus on the entire process instead of just parts of it.Volvo Penta in Vara has earlier done value stream mapping but without good results since they didn?t take set-up times and imbalances in account.
