At the Division of Electricity at UppsalaUniversitythere are ongoing researches, including a research concerning turbo generators.Turbo generators produce a large share of electricity in the world; however they are costly mainly due to the fact that the cooling and ventilation that are needed to eliminate the excess heat from the generators are expensive. Turbo generators work with high efficiency and in this project, the main task is to simulate a generator while taking into account that the generator must be designed against self-oscillation, centrifugal force, exhaustion and heat. The turbo generator must be simulated without being too expensive and complicated.In this project, the dimensions of the turbo generator depend on the efficiency of it, and where the losses are in the generator. Furthermore, the optimum values need to be chosen with the help of the ACE simulation program. The report begins with an introduction describing the project followed by a task description that is dealing with the project.

This thesis was created in an attempt to examine the concept of cultural heritage. What is cultural heritage to us and why do we treat it in the different ways we do? In my attempt to find an answer to this I have chosen to concentrate my interest on a situation where historical objects have been preserved as well as destroyed, Iraq 2003 until 2007. In my research I have divided the Iraqi cultural heritage in three different groups based on the different treatments they where exposed to during the occupation of Bagdad and the aftermath. For each group I have chosen one object or a category of objects to be a representative examined.

This essay analyses the European Food Safety Authority's (EFSA) legitimacy. Theories on input- and output legitimacy are used in the examination. After analysing stakeholder representation, forum for deliberation, transparency, independence, and information sharing, input legitimacy in EFSA is assessed to be high. Output legitimacy was examined through the authority's outcome effectiveness, which was divided into compliance and effectiveness. Since food safety is an immense area, two important parts were chosen for the analysis of output legitimacy; transmissible/bovine spongiform encephalopathy (TSE/BSE) and genetically modified organisms (GMO).

The purpose of this thesis is to understand the reasons to why management consultants choose to leave their positions at large and established management consultant companies. The empirical data are made up of eleven interviews with men and women, both management consultants that have left their previous positions as well as a consultant who has chosen to stay with her first company and a representative from one of the large companies active within the management consultant industry. We have used the Job Embeddedness Theory combined with theories about identity, legitimacy, institutional norms and gender in order to understand the thoughts and reasoning behind the management consultants´ resignation. We have found that issues with the work itself and characteristics of the industry prevent the management consultants from being embedded within the management consultant company. Rather, some of the characteristics of the industry such as ?up or out? and the need to constantly perform work as a ?pushing-out mechanism?.

A change has occurred in terms of recruitment to teacher education. From having been an educationof high status and reputation, a reduced application rate has led to lower admission requirementsand thus that students with much lower educational qualifications entering, which in turn means thatthe education status and reputation have been reduced significantly. Mathematics, on the other hand,has always been a topic of high status and reputation. Although there are few students who chooseto study to be a mathematics teacher. By conducting a survey of students on teacher educationtoday, both with mathematics and other approaches, I wanted to get answers to my questions aboutwhat influences students' choice of education: who are the students studying to be teachers inmathematics? Do they distinguish themselves from the student teachers who studies to be teachersin other subject specializations? Pierre Bourdieu's sociological ideas about cultural capitaltransmitted from parent to child constitute the theoretical framework of the study.Early in the study, I noticed that there is a difference between students studying to be a teacher inpreschool, primary or middle school and them studying to be a teacher in secondary and highschool, especially in terms of the mathematics student teachers.

Stress and burnout is a common healthproblem among different workcategories today. The aim of this study was to investigate possible presence of stress and burnout among radiographers and if there was a connection to number of years in the profession. Maslach Burnout Inventory was used as an instrument to investigate the possible presence of  burnout, supplemented with questions about stress. The instrument contained a total of 33 questions and was handed out to two hospitals in south of Sweden with a total of 51 respondents. The study showed that the most stressful situations arose due to workload, negative stress, bad working environment and high time pressure.

AbstractParticiapation from the citizens in a democratic society is one of the ground pilars for the function of the democratic society.

The intention with the study is to describe the home and life conditions for boys at the age range between 13 to 18 year, who has been under custody according to the § 2 LVU.The empiric is 21 real court cases, judged in Stockholm and to Stockholm counted surround-ings 2006, in which the range of the boys were representative.A text analyze method is used to execute the study. The study penetrates the life situation of the caregiver and how their situation affects the boy and the boys actions.The total conclusion of the study, based on an ecological evolution perspective, is that life-situation of the caregiver affects the boys and the boys actions.The boys are affected negatively by the situation of their caregivers, and according to the study, the boys have established own problems, like difficulties in school, criminality, or other psychological diagnoses. They are also often exposed to physical or psychological violence by the caregiver. Additionally the conclusion is that the caregiver neglect the boys in many other ways, prior themselves and their needs before the boys..

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

Difficult calvings and stillbirths are problems in Swedish dairy production that result in large expenses for the farmers and welfare issues concerning the animals. A common opinion is that the live weight of SRB and SLB is increasing, and whether increased weights have caused the increase in calving problems has been discussed. The aim of this study was to investigate the relationship between the relative birth weight (calf/cow) and calving difficulty and stillbirth, respectively. The importance of breed and parity for the relative weight has been investigated, and comparisons with previous studies have been made to evaluate whether the relative weight has changed over the last decades or not. The study was based on 807 calvings, registered during the period 1993-2003 in the experimental dairy herd of the Swedish University of Agricultural Sciences (Jälla).

The present study examined high school students? attitudes to higher education at university/college and their study engagement in an industrial town in klarälvdalen in the county of Värmland. The main research question was whether there are any differences between students in vocational and theoretically oriented programs regarding their attitude to higher education and study engagement. The results was also compared with a study with the same research question conducted in Countryside town in fryksdalen, Värmland county to see whether attitude and student engagement differ between high school students in different parts of Värmland. The method used was quantitative with data collected by using questionnaires.

The purpose of this paper was to study the various organisations that work with drug abusing homeless people in Lund. We have tried to compare the possibilities they have to change the way the homeless people look at themselves. The organisations that we have studied are Aluma, Diakonicentralen, the shelter Piletorp and the social welfare office.The methods used to collect data were interviews with professionals and homeless people as well as reading literature. We have used Ted Goldberg's (docent in social work at the university in Stockholm) theory. He writes that you have to be a significant other to persons with deviant behaviour to be able to help them become a part of the society and to change the way they look at themselves.

Genomic selection (GS) is used for selection of breeding animals of dairy cattle. GS is though not as extensively used within the beef industry. One reason for that is the low accuracy (rTI) of the breeding value that is of great importance for the final genetic gain. Causes to the low accuracy are high effective population size, a small reference population and a genetically differentiated population. There is however a market for genomic selection with High Density (HD) tests for beef cattle.
