A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

During the last decades the evolution of information technology and the increasing ability to access information have been discussed in many ways. In the beginning the focus was on the technology but now the discussion is more and more about the use of information and how to develop knowledge out of it. There is an ongoing discussion about the difference between knowledge and information. The subject of this Master s thesis is to find out if and how the Swedish elementary school has written into its mission statements to help the pupils to become information literate. For this purpose I have examined literature about information literacy and pedagogic as well as legislation and other documents that control how the Swedish elementary schools work.

The purpose of this Master?s thesis is to examine and analyze the discourse concerning a new public library in Stockholm. The paper further discusses how this discourse corresponds with what is written about public libraries in a number of national and international documents. To do this I have utilized the discourse theory of Laclau and Mouffe. By using some of their instruments I have established the discourse around a number of keywords.

This paper investigates how Swedish upper secondary school students relate to the financial support available from the Swedish state of education. It also looks at the attitudes of such students to the new CSN[1]truancy rules as they apply to school politics.Is there a difference in students? attitude to these truancy rules and does that difference depend on the students? socio-economic standard, whether they come from a wealthy background or a marginalised society or whether they are ethnic Swedish? Does this in any way affect the attitudes of the students?This financial support is only paid to those students who do not skip school. If they lose their right to this contribution because of truancy, their parents will also forfeit the right to the financial subsidies to which they may be entitled. Naturally, this may affect students in different ways, depending on what kind of financial situation their family is in.Do some students go to school out of their own financial interest or out of that of their parents? Through focus-group interviews, students have expressed their opinions, told about their experiences and stated their attitudes with regards to these matters.

Increasing innovation and entrepreneurship has been identified as a key target for sustained growth and welfare, both in Sweden and abroad. Therefore, many countries have recognized the need to equip students with entrepreneurship education and to integrate skills associated with entrepreneurship into the various curricula.To shed light on entrepreneurship education within business curricula, a case study focusing on the first two years of the Bachelor program at the Stockholm School of Economics (SSE) was conducted. The study was based on interviews with students, alumni and scholars with a background of entrepreneurship. Insights from respondents were compared with leading research on entrepreneurship education, to evaluate the program's approach.Primary findings from the qualitative analysis showed an overall lack of entrepreneurship education in the early stages of the program. Entrepreneurial "know-how" knowledge was an insufficient component of the SSE program and a barrier for why more students did not pursue a career in entrepreneurship.

Syftet med uppsatsen är att identifiera, beskriva ochanalysera den kunskapsöverföring som sker mellan anställda(lärare och ledning) som jobbar på grundnivå på ettuniversitet. Vi vill som resultat ha bidragit till diskussioneninom detta forskningsområde genom att ha ökat förståelsenför universitet som objekt för Knowledge Management. Uppsatsen gör en kvalitativ ansats med semi-struktureradeintervjuer för empiriinsamlingen. Materialet analyserassedan kritiskt med teoriramverket i bakhuvudet ochintressanta vinklingar och existerande heterogenitet lyftsfram. Ett tydligt och särskiljande drag på institutionen var att ledningen inte uppfattades ha den roll som man finner i fleraandra organisationer.

Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.

This report focuses on work schedules in the retail sector, where work schedules are dynamic and change according to the needs and work schedule is a requirement for an effective structure of the work. This structure is important for maintaining a good order and all this is a requirement for a profitable business for both long and short term future. Work schedule also contributes to safety at the workplace. The purpose of this study was to investigate the transfer of knowledge by work schedules. The HRM employee we interviewed worked in Reitan Servicehandel Sverige AB which includes 7-Eleven, Pressbyrån and Shell.

The aim of this thesis was to investigate the methods used by teachers and childrens' libra­rians concerning their work with fiction at the junior school level. Based on a series of qualitative interviews and by compiling a list of short summaries of literature relevant to our thesis we wished to reflect on the manner in which the respondents see themselves in their teaching roles.We also wanted to discover what problems they had in their work and what visions they held for the future. The methods used by the teachers were mainly: reading- both aloud and individually, process-oriented writing, use of fiction in thematic studies and dramatization. The teachers' aspirations for the future included a centrally situated school library and further education in children's literature. The teachers take the needs of their pupils as a starting point and build on these needs - using many years of literary teaching experience as a foundation."Booktalks" for the children and intermediaries (teachers ...)and education in books and library systems are the childrens' librarians main literaturepedagogic methods.

BACKGROUND: Pressure ulcers are unpleasant and painful and causes anxiety not only patient but also for the relatives. It also results in longer hospital stay and increased costs for health care sector and because of this it?s important to identify and survery the origin and what preventive measures there are to prevent pressure ulcer. AIM: To illustrate the nurses´ work to prevent the origin of pressure ulcers. METHOD: A general literary study where scientific articles were searched and found in electronic databases and through manual searches.

The idea to create authentic learning situations where students are highly integrated made me want to try to develop a new method in the course Restaurant and Catering B MAKU 1208 (another field practicing cuisine). In my quest to do just the practical part as rewarding, stimulating and efficient as possible for the student, I planned for a training model with   focus on group interaction.The implementation of the model for learning was to strengthen students confidence both in themselves and in each other, stimulated to greater cooperation and it has also provided an incentive to the student's own development but not least, a growing self-confidence for many students. Several have also had an increased sense of knowing something, to have something to contribute and that their labour input actually was needed. While highlighting that further education to seek knowledge strengthens the individual's skills and consolidates and increases deeper knowledge in the professional field.In conclusion, training should be done in both individual and group basis for optimal learning process..

Intranets can streamline workflow processes, improve communication and add value to the employees of an organization. Companies that don?t take advantage of the potential in their intranet is a common phenomenon. In connection with a migration project dealing with a switch of content management system it turned out that SAS Technical Services lacked clear objectives and strategies for the use of their intranet. Thereby they didn?t make the most of the possibilities an intranet brings.The work with this thesis began with collecting the experiences the company could take with them from the migration project.

This essay examines how high school teachers in physical education and health thinks about assessment and grading. The essay show how teachers assess pupils during lessons and how teachers grade their students. The survey was based on interviews, in which six different teachers answered questions on the topic of assessment and grading. The issues surrounding assessment was linked to the theoretical concepts of formative and summative assessment, to see if the assessment methods teachers use. The issues surrounding grading was related to the theoretical concepts of validity and reliability in order to see how similar the grading is.The essay provides a picture of how the assessment and rate again looks different teachers.

Do ceramics have to be static? This was the question that spurred me into this work, and what kept me working on to achieve the possibility of motion in my ceramic objects. By combining the knowledge gained through my former education as an avionics technician with my interest in the ancient ceramic craft, I strive to create kinetic ceramic handicraft suitable for interaction with an audience.By a series of different phases I slowly go from understanding what kind of motion I want my objects to have, to actually realizing this motion in three-dimensional objects. Through the use of simple models made from corrugated fiberboard followed by more advanced plaster models, combined with different complementary materials such as bicycle inner-tubing and recycled aluminium cans among many others, I, through a vast series of testing, slowly build up a knowledge base later applied to the ceramic objects.The result is for me a success; I have found a way for me to combine ceramics with mechanics. Through this I have created kinetic ceramic handicraft intended for interaction with an audience..
