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.

The overall aim of the study was to take part of teachers' experiences and work force mother-tongue education and literacy development in the Sámi School. The study was conducted through interviews with twelve teachers who teach at two Sámi schools. The focus has been on looking how to work with native speakers teaching at the Sámi School, what factors promote / hinder students' development of their first or second language, and the importance of collaboration between the schools` various professions work with multilingual students reading and writing skills. Through interviews of various categories of teachers, I have tried to visibility problems of the education of minority language children and their reading and writing skills. I discuss the teaching, the importance and the lack / availability of communication and consensus between different categories of teachers.

The aim of this thesis is to practice the theoretical methods that are concerned during the product development process of two new products. The theoretical concepts that embody the two products are created out of a product specification which is given by a commissioner with a private interest. The primary tasks of the design of the concepts are aimed on the products shape, which is to be created as a flexible structure by using silicon rubber as material.The storage box is a further development of the already known food storage box, or lunch box, which is common used in consumer kitchens. The main idea is to design a flexible product by using silicone rubber. It will able the storage box to be compressed when it is not used, be storage friendly and not consume more space than necessary in a storage compartment.

Large-scale land investments is not a new phenomenon, but increasing prices on food and agrofuels have inflated prices on land and has led to an enhanced interest in landinvestments from a range of different actors. The ProSavana project in the Nacala corridor in the Nampula province, northern Mozambique is a large-scale land investment with the purpose of establishing intensive commercial agriculture and is planned to be implemented this year (2013). The project is financed by Brazil and Japan in collaboration with the government of Mozambique. It is not quite clear how large-scale land investments affect the areas they are implemented in and how they can affect the possibilities for sustainable development in these areas. Both opportunities and problems can be observed within the social, economic and ecological dimensions of sustainable development.

ABSTRACTA Qualitative Discursive Analysis of Eight Contemporary Geography BooksTeacher Training with an Intercultural Profile 2006Author: Susanne LjunglöfTutor: Jan-Eric MattsonThe aim of this paper is to describe which discourses concerning the different continents problems, future and development that I can find in the descriptions of the continents in a number of contemporary geography books.The aim has been divided in four questions:- Which aspects of the continents problems are expressed in these geography books?- Which impressions concerning the continents development and future are expressed in these geography books?- Which conceptions about the population in the different continents are expressed in these geography books?- Which cultural reference creates these discourses?The method used for conducting this study is a text analytical method called general discourse analysis.My conclusions:- The different continents problems, development and future are described through entirely diverse discourses.- The reviewed geography books take their origin i a western perspective in their description of the different continents.- As a reader it is always important to be aware of the ethnocentric perspective that could be expressed.

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 purpose of this paper is to describe and analyse the Chinese destination of Hainan, with background in a globalizing tourism destination development, for tourism from Finland and Sweden. The questions at issue are regarding what kind of an impact the status as a special economic zone have had upon Hainan, what kind of conditions there are for tourism on the island, in what form participants of the tourism industry want the development to proceed, what the prevailing trend is for distant destinations for Nordic markets and also regarding what kind of potential there is for organized tourism to Hainan from Finland and Sweden.As a foundation for the paper, I?ve composed a theoretical reference for knowledge of China, Hainan and the study of destinations. The sources of secondary kind are literature related to the subject. The primary sources are mainly interviews, field work done at Hainan has given a concrete and personal knowledge of the place.

Human Resource Management (HRM) has an increasingly strategic role in today?s organizations as the supply of managers is an integral part of the strategic work. In order to retain competence and knowledge, firms are usually designed so that the employees can develop their careers within the firm. Company X is a company in the financial sector and is an example of such firm. However, at Company X: Department Y, very few employees apply for the management positions when they are announced.

Media spelar stor roll i vårt samhälle. TV är det massmedium vi använder i störst utsträckning. 90 procent av barnen som är mellan nio och fjorton år ser på TV dagligen. Det är inom denna åldersgrupp (närmare bestämt 11-12-åringar) vi valt att göra vår undersökning. Undersökningen berör frågor som vilka TV-program barnen ser på och om barnen kommer i kontakt med dokusåpor? Vi kommer även att se närmare på vem barn tittar på TV med och om det finns någon skillnad mellan pojkars och flickors TV-tittande.

Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.

Det här är en intervjustudie om 22 intervjuer med gymnasieelever vid Barn och fritid-, Natur- och Fordonsprogrammen om deras sociala bakgrunder, deras föräldrars yrken och elevernas syn på sina val av program om de upplever någon orättvisa i det observerade sambandet som kallas den sociala snedrekryteringen. Syftet med studien är att ta reda på hur eleverna upplever sin situation i ett rättviseperspektiv. Den här studien bekräftar det nämnda sambandet, de flesta elever väljer program och vidare studier och arbeten i nivå med sina föräldrar. Detta är särskilt tydligt vid Natur- och Fordonsprogrammet. På Barn och fritid var det mera blandat.

The purpose of this study is to find out how some Swedish preschool teacher discussing how children's Swedish colloquial interaction can be enhanced in the free play. In this case where children are aged three to five.My research questions in the study are:-          What type of free play do preschool teachers talk about in relation to children's Swedish colloquial development?-          What do preschool teachers say about child's colloquial interaction?-           How do preschool teachers reason regarding in what environment children?s colloquial interaction occurs?In my study I have used an interview with elements of a visual method called The Diamond. The approach is that the participants in the interview will be enhanced to discussing about a wise certain number of images. These images are then to be ranked accordingly with a specific theme and terms.If a child has difficult to speak, you can take help of  the interest the child has, the child can tell you and the other children what he or she know about the interest.

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.
