There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).

This report was performed in order to evaluate a new technological measure and focuses generally on a heat pump system to a HWC-washing machine. The client is Asko Appliances AB, a company well known for its environmentally friendly products. The goal of this study was to improve the energy efficiency of a washing machine by combining a heat pump device to the heater of the wash water, in order to reduce the energy consumed for heating the water. Besides reducing the energy consumption in heating the water, the washing machine was required to meet low noise and short operating time specifications. For that purpose, nine trials in three test series have been carried out.

Background: There have been several reforms within the Swedish educational system since the 1960´s, not only within the elementary school but also within the teachers? education and the school leaders´ educational program.Aim: My aim with this study is to explore if teachers´ expectations and experiences of school leadership have changed since the many educational reforms began in the 1960´s.Method: For this study I have a used a comparative design. By making qualitative interviews with five teachers born in the 1940´s and five teachers born in the 1980´s I have then analyzed the result.Result: Regardless of the 40 years of age difference and the multiple reforms within the educational system in Sweden the result shows that the teachers in this study did not have any clear expectations on their school leaders as they started their careers..

Purpose: Our purpose is to examine how ExTe works with values and attitudes and if it has any connection to their success.Research questions: Does attitudes and values have anything to with ExTes success?

Does ExTe follow their written Value book and do they continuously and active work with it?Approach: We have used a deductive way of reasoning and a qualitative study to gather the information needed. We have interviewed four staff members at ExTe.Conclusions: ExTes continuously and deliberately work with values and attitudes do have a meaning for their success.

En majoritet bland ledare i olika organisationer har en bakgrund som storasyskon eller ensambarn (Hudson, 1990). Denna studie genomfördes för att få svar på om personer med ledaransvar skiljer sig åt gällande syskonplats och locus of control jämfört med de personer som inte har ledaransvar. Ledare och medarbetare på en statlig myndighet svarade på en enkät gällande plats i syskonskara, erfarenhet av ledarskap och locus of control. Resultatet visade att sistfödda i detta urval hade en högre grad av intern locus of control än förstfödda vilket kan tyda på en annan typ av sistfödd på denna myndighet. Urvalet var dock bristfälligt (N = 48) och slutsats kunde inte dras utan att riskera ett felaktigt resultat..

Purpose: To evaluate the management development course held at FöreningsSparbanken in Ronneby during 2000. The evaluation aims to map and describe what effects the course has had on the participants. We will assess to what degree the effects meets the objectives of the course set by the manager of the bank (future management recruitment, leadership, change catalyst, aligning the strive towards a shared organisational objective). Above mentioned also implies that the organisation should be influenced in some regards. Conclusion: Our conclusion is that all of the participants have as a result of the course increased their emotional intelligence in varying levels.

Tidigare forskning har fokuserat mycket på vad entreprenörskap är, och vem som är en entreprenör. Tidigare forskningar visar att en entreprenör är något man föds till. Det finns en hel del forskning om entreprenör, entreprenörskap där man fokuserar på entreprenörens personlighetsdrag. Bland den forskning som finns existerar två huvudsakliga uppfattningar. Den ena menar på att man föds till entreprenör medan den andra anser att entreprenör egenskaper är något man kan utveckla genom olika affärserfarenheter.

Debatten om ekologisk kontra konventionell odling har blossat upp allt mer, förespråkare från båda synsätt har sagt sitt genom slagfärdiga debattartiklar och diskussionen har sedan fortsatt vid middagsborden runt om i landet. Denna kandidatuppsats i ämnet landsbygdsutveckling syftar till att undersöka vilka drivkrafter som kan ligga bakom olika aktörers engagemang i jordbruksfrågor och hur de ser på vad som är en hållbar livsmedelsproduktion. Uppsatsen syftar även till att utforska hur informanterna framställer sig själva och andra aktörer i debatten som förts kring ekologisk kontra konventionell odling. Vem bär enligt informanterna ansvaret för jordbrukets utveckling? Behövs en radikal omställning i hela livsmedelsproduktionen för att nå mer hållbarhet eller räcker det med att enbart göra små justeringar? Det empiriska materialet består till största del av fyra informanters syn på dessa och liknande frågor. Detta material har sedan analyserats med inspiration från Erving Goffmans teori om intryckskontroll och Ulrich Becks teori om risksamhället..

AbstractTitle: The signification of the traditional gender roles in misuse treatment ? the experiences of eight addictsAuthor: Andersson Malin, Gunnarsson AnnelieSupervisor: Lindberg OddThe purpose with this essay is to study if the staff in two LVM treatment facilities do strengthen the traditional gender roles in their daily work and interactions with the clients. The aim was also to study if the staff reconstruct traditional gender roles and if this can be seen as an advantage or disadvantage in the treatment. Finally the aim was to investigate if the staff encouraged the clients to break loose from the traditional gender roles. A qualitative approach using face to face interviews was used.

In recent years, the demands for effectiveness and evidence in social work have increased in all work areas, including that of healthcare. This has sparked the discussion on concepts such as practical- and theoretical knowledge and their respective roles in social work. In the light of this, the purpose of this candidate thesis is to investigate healthcare social workers understanding of practical- and theoretical knowledge in the working process as well as their respective influence and importance. This candidate thesis is based on three interviews with social workers from different departments in Norrlands Universitetssjukhus in Umeå, Sweden. To provide range to the thesis, the interviewees were chosen from a purposeful sampling.

A literature study and a field trial have been carried out in order to investigate the physiological response of potato plants to different soil moisture levels. Higher yield, quality and number of tubers can according to the literature be obtained if constant high soil moisture is kept during major parts of the growing season. A field trial was set up where drip irrigation was used as an alternative to conventional irrigation techniques to maintain high and constant soil moisture. The application of water in the drip irrigated area was monitored and adjusted on a daily basis so that the soil moisture stayed as close as possible to the recommended level. The sprinkle irrigated area was irrigated according to traditional practices with approximately 35 mm every 7th to 10th day depending on the whether.

Fairtrade is a certification of products that has grown from the criticism of conventional trade. By increasing the focus on the producers? economic and social conditions, poverty can be fought and the producers? voice in the marketplace can be strengthened. Fairtrade City is a certification for municipalities who wish to engage in ethical consumption. The purpose of this thesis is to understand the Fairtrade City concept and how this can be a tool for working towards sustainable development. To be more concise, we want to answer the following questions: Why does Örebro municipality work with the Fairtrade City certification and how can Fairtrade City be used as tool for working towards sustainable development? The thesis is based on qualitative interviews and e-mail interviews with members of the steering committee for Örebro Fairtrade City and on literature studies. We have in our thesis identified Örebro Fairtrade City as a result of 1) that Örebro municipality through Fairtrade City wants to change their surrounding environment by engaging in ethical trade 2) that the surrounding environment effects Örebro municipality through isomorphism regarding its way to deal with sustainable development 3) that the municipality through its work with ethical trade becomes legitimized by their surrounding environment.

This essay is a textbook study where I aim to review four textbooks regarding some historical events in the subject History. The textbooks are used in junior high school and the historical events are as follows: the genocide that happened in Congo during the leadership of king Leopold II, the genocide on Armenians in the Ottoman Empire, the Holocaust and the Vietnam War.By performing this study I wanted to answer these three questions:What differences and similarities can be found in how the events circumscribed?How much space do the various events have and has it evolved through the years 1980-2009?How can this be explained?The study has been analyzed from a post-colonial perspective and the recurring patterns that appear show how the texts are post-colonial. This means that the authors of the textbooks are writing about the same subjects, but in very different ways..

Today there is a shortage of skilled IT-technicians in Sweden. It is approximated that Swedish companies can hire 31 000 IT-technicians in 2015 and the need seems to increase in the coming years. One proposed solution to this problem is to make programming more desirable to youths. In this study we attempt to investigate the effects of an introductory course in computer science on youths? (16-17 years old) in a classroom setting.
