This Bachelor of Science thesis was carried out at Metso Panelboard AB, located in Sundsvall, Sweden. The work lasted for 10 weeks and began at the end of February 2007. Metso Panelboard is one of the leading suppliers of complete lines, single machines, engineering knowledge and after-market services to the fibreboard industries. The task involved building a 3D-model of a dryer cyclone in the CAD-program Pro/ENGINEER. A dryer cyclone is the part where the tree fibres are dried in the process of manufacturing fibreboards. Currently, it takes about two weeks to draw a dryer cyclone. By creating a 3D-model of it, which should have the functionality to be generated to different sizes, the goal is to decrease the drawing time to about 20 hours and to increase the quality of the work. This report includes the fundamental theories behind the manufacturing of fibreboards with focus on the dryer cyclone.

AIDS is a huge problem in the world and it is spreading rapidly, especially in Africa. Botswana is one of the worlds worst-hit countries, with over one-third of the inhabitants infected by HIV/AIDS. The measures that have been taken to stop the spread of AIDS are to inform and enlighten people on how the disease is spread and how to protect oneself. The aim of this thesis is to investigate what different ways of informing people about AIDS different organisations make use of in Botswana. The thesis also addresses how some receivers of the AIDS information experience it.

Background: Mutual funds have become an important part of the Swedish deposit market. Savings in mutual funds add up to almost 20 percent of the households'assets. When the pension reform is carried out all employees are going to have savings both in mutual and bond funds. But only if the fund overperforms the market it is worth investing. Purpose: The purpose of this study is to explore if Swedish mutual funds have generated higher returns than market portfolio in the late nineties.

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

This thesis analyzes the media debates generated by the election of Omar Mustafa to the board of the social democratic party, and the appointment of the conservative Minister of Labour, Elisabeth Svantesson. More specifically, the aim is to analyze newspaper material through a discourse analyze, to see if and how religious affiliation effects the possibilities to act as a political representative. Theories of othering and intersectionality serve as theoretical points of departure. Further, chains of equivalence from Laclau and Mouffe?s discourse theory are used to study how categories as ?us? and ?the other? are constructed in the material, and how these processes of categorization relate to the intersection of religion, gender and ethnicity.

AbstractBackground: The company that this report addresses is, at time for investigation, in the midst ofa change in organizational culture, where two departments with different core competencies arebrought together into one. The purpose of this study is to review the potential problems that mayoccur in the change process when one or more subcultures come into conflict with organizationalgoals.Purpose and methodology: The reason for performing this study and the objectives are toexamine how subcultures influence and respond to organizational changes. The survey isconducted with a bottom-up approach in which participation in daily activities with thesubgroups is the foundation. The management's perspective has been omitted in consideration ofpast literature in the field where focus most often has been on their thoughts and views on theprocess of organizational change. The method used is participant observation and interviews.Results and Conclusion: Subcultures exist and they do affect an organizational change.

At the time being there is limited experience within turbine decommissioning in Sweden and the economic effects are unknown. Despite this, there are expectations that revenues generated by sales of materials will cover decommissioning costs. The model developed identifies thirteen parameters that vary between different types of turbines and that affect the economic consequences of decommissioning. The three most important parameters are turbine location, tower material, and the scope of decommissioning. Trends in the wind energy industry show that these three factors are developing in a manner that increases decommissioning costs dramatically.

Several researches asserts that as teachers are responsible for the content of teaching and by formulating teaching "Why, ""How" and "What", that will also give signals to students about what is important knowledge. This essay addresses the difficulties teachers may face in terms of self-disclosure student texts and awareness of this in the design of teaching and writing tasks. Research shows that self-disclosure and self-therapy student texts exist and that teachers are experiencing a difficulty with regard to assessment and treatment.Through qualitative interviews examined seven teachers' design of any, to the student, self-disclosure information from curriculum and policy documents. Another purpose of this paper is to examine the extent to which teachers, through the information they give to their pupils, may affect the texts students submit. It turns out that the respondents are united in the belief that they, through their data, may affect the texts they receive from their students when they are the ones that control the content of teaching, and they agree that the curricula gives them a great choice for design data. The survey shows that the perception of the curriculum that will open up for self-disclosure texts differ as some of the respondents believe that the curriculum is very much about the students way to express feelings and opinions, while others believe that they may try to package this data in another purpose or exercise.

This thesis addresses the driving forces behind the Swedish state?s procurement of Helicopters 14 and 16 and the decommissioning of Helicopter 4. These actions have significantly affected the Swedish Armed Forces, especially the Helicopter Wing, in carrying out their operational tasks. On numerous occasions the Helicopter Wing has been unable to perform its tasks. For instance, the Nordic Battle Group 08 had no helicopters to exercise with and, until recently, Sweden had completely lacked the ability to hunt submarines with helicopters for almost ten years.This thesis also aims to compare the decisions in 1999-2000 regarding Helicopter 14 with the decisions in 2010-2011 regarding the acquisition of Helicopter 16, to find if there is a general trend and how much the Armed Forces were able to influence decisions.

This paper investigates the possibilities to construct automatized portfolios based on optimizations strategies that could outperform comparable indexes. The study is based on time-series of Swedish stocks dating from 1986 to 2006. In the research four different portfolio optimization techniques were studied. These were: the Classical Markowitz Approach, Mean-Absolute-Deviation, Minimum-Regret and Conditional Value-at-Risk of which the three latter are based on generated scenarios. The behaviour of these models was studied for different choices of parameters such as backward time-horizon and targeted average return.

The aim of the study was to examine collaboration and professional perspectives on the best interest of the child in regards to working with unaccompanied asylum seeking children. Firstly, our result show that counselling is available for the unaccompanied children from case workers, staff, school counsellors and emergency psychiatric care. All of the participants in this study describe the need for long-term counselling for unaccompanied children, however, providing the long-term counselling is not the primary purpose of the organisations in question. Therefore an additional service-provider working with counselling is a necessity. Secondly, the study explores the participants? professional perspectives on the best interest of the child.

Man?s impact on the environment is something that increasingly becomes topical in today?s society. Because of this, several companies have started to take interest in the effects they?re responsible for, not least considering their image. Emissions of carbon dioxide generated from goods traffic are accountable for a large part of the total emissions of greenhouse gases in the world.

The purpose of my study is to examine how four preschool teachers go about using the term play in children's early mathematical development. In order to fulfill the purpose of this study, I have the following questions:How the preschool teachers visualize mathematics in children?s play?What reflections have the preschool teachers about the importance of play for children's mathematical learning in preschool?How do the preschool teachers see on their own role in the children's play?In this study, I have conducted a semi-structured qualitative interviews based on the interviews with four preschool teachers from various departments in a preschool. I have also conducted some observations to complete my study. Whereas in my analysis of the researched material, I have used Vygotsky's theory.The survey shows that the preschool teachers are aware of the use of mathematical language and concepts in children?s different activities which were conducted daily in the preschool.
