This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg. In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels. Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time. The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

The main purpose of this study is to investigate the unintentional learning that happens during the use of computer games. With the use of interviews with students in the ages 13-15 who all have played the game series Assassin?s Creed, and then compared them with students who does not play the game, we have been able to identify that some learning is taking place, but that the student?s attitude towards the subject, and their maturity, also is vital for the learning. Even tough, the students who didn?t really enjoy history as a subject showed better knowledge after playing the game, than the students who hadn?t played at all, which indicates that computer games can be a good source for learning.

Several thousand years of human impact on the landscape in the form of cultivation is the reason to many nature- and culture values in the agricultural landscape today. Intensification and rationalization has led to vast monocultures and has forced many farms to close down. These trends have increased in the last years and constitute great threats to the values of the cultivation landscape. The purpose with the environmental objective A varied agricultural landscape is to protect these values. The environmental action plan of the municipality of Lund (LundaEko) 2006-2012 is built on the 16 national environmental objectives. The purpose with this paper is to put together material that the municipality of Lund can use in their work with modifying the local intermediate goals for the environmental objective A varied cultural landscape. The overall issue for this paper is ?What has happened with the state of the cultivation landscape in the municipality of Lund since LundaEko was approved in 2006?? The paper seeks to portrait the current conditions of the following fields: meadows and pastures, organic farming, exploitation threats to agricultural land, landscape elements with cultural values and species that are threatened.

The purpose of this master thesis is to show how a chosen actor in form of the Swedish union organization IF Metall (the Swedish union for metal- and industrial workers) works with pro-reading activities. The project being scrutinized is the Read to me dad-project which aims at fathers who are not used to reading activities within the LO-group (the Swedish Trade Union Confederation). The methods used are interviews and literary studies. The theoretical background of my discussion is based on three education ideals. The neo-humanist ideal emphasizes the personal improvement through literature.

Purpose: The purpose of this qualitative study was to illuminate and compare how teachers and parents are describing the homework. The study will also attempt to answer these issues; How is the purpose of the homework described from teachers and parents? How are the effects of the homework described by teachers and parents? How do teachers and parents describe the responsibility for the implementation of the homework?Methods: Qualitative study, a comparison between teachers and parents description of the homework phenomenon. The material that forms the discussion are fetched from blog forums.Summary of conclusions: The Swedish school system is based on democratic values. This means that the students are supposed to gain equal opportunity for qualified education independent of their socioeconomic backgrounds.

The review of Integrated green spaces in urban areas ? A case study of inner Brisbane highlight the significance of addressing characteristics, qualities and landscape values in our outdoor environment. The importance of green spaces to the wellbeing of people in the city and the ecological, social and cultural values they carry are widely recognised in the field of urban and regional planning. At the same time population growth, climate change and urban development put planners and scientists in a challenging position where new solutions must be put on the agenda in order to accomplish sustainability. Open space strategies, collaboration between stakeholders, public participation, learn from earlier failings and a ?value-led? approach facilitate the managing of open space. Brisbane is located in the fastest growing metropolitan region in Australia. The city´s open space landscapes offer cultural, geographical, recreational, social and scenic amenity assets, which make a major contribution to the regions identity they a wide world known for.

The purpose of this study is to analyse the significance of the national assessment in highschool education, including what the teachers express about the new instructions currently coming from the Swedish National Agency of Education, concerning a more central control of grading the national assessments. This study also covers the teachers individual responsibility when it comes to grading the national assessments. The purpose of the national assessment is to secure that grading and the education level in the country is equal. This is a qualitative study useing the method of a group discussion intervju (focusgroup intervju). Five highschool teachers took part in the discussion with questions that had been decided beforehand.

This thesis focuses on interaction in netbased education. The purpose being to increase awareness about what promotes interaction in netbased education through understanding and categorizing the students? opinions . My method is qualitative with a phenomenographic approach. I have conducted a netbased survey with 21 respondents who have completed a netbased course. Further I have followed up and chatted with 7 of the respondents in the survey.

Public health is a concern of many important areas of society and it is therefore of great importance to examine and expand the goals of public health work within different sectors, e.g., school. Sexually transmitted diseases, sexual violence and mental health problems related to sexual orientation are some of the public health problems in society today. Throughout childhood and teenage years, norms and attitudes regarding sexuality and coexistence are formed, which means that school is an important arena when it comes to creating proficient conditions for    coexistence and sexual health. The quality of sex and coexistence education in Swedish schools differs in quality; for content and magnitude vary greatly among schools. It is, therefore, of interest to study how students experience sex and coexistence education, like prioritizations and desires.

The theory chapter is based on a model about brand identity, ?Brand Identity Prism? (Kapferer, 2008, s.183). This model contains six elements which we have supplemented with theories about personal branding. This because the focus and theory on a person's brand identity is almost non-existent. The purpose of the study is therefore to examine how editors at fashion magazines are working with their brand identity in the personal brand and thereby create an understanding of the identity function.

This essay is written at the university of Linköping and is a part of the teachers education. The intire essay is available on CD-rom. Its content is directed towards teachers who entirely or partly works, or want to work, in computereducation. The CD-rom contains both textmaterial and presentations, with teacherinstructions, wich are directly appliable in teaching computers. The teachingmaterial on the CD-rom is based on an empiric survey with different computerteachers.
