The purpose of this degree project was to build laboratory equipment for a new course in power electronics that starts this autumn 2010 at Uppsala University. The equipment is intended for student labs and it covers the most important areas of the course including rectifying, buck-/boost-converters and PWM-modulation. It is built as one sealed unit where all the electronics are built-in but visible and it has a connection board where students safely can connect the different circuits. The project has advanced from theoretical studies of circuit design, choosing of components and simulations to drawing the printed circuit board (PCB), soldering, case building, final testing and troubleshooting - basically most steps from an early idea to a final product. Measurements on the final product gave about the same results as the earlier simulations of the circuits and the result is overall satisfying..

AbstractThe purpose of this investigation is to find out how the pupils can discover and to feel joy in their creative art activity and also to believe in their own ability. The aim is to figure out if creative art activity is able to raise the pupil?s self-image. By literature, pedagogue interviews, and interviews with pupils at the age of ten years old and by action research is the way that I have searched for an answer for my question. The main result is that fantasy, creativity, courage and lust are important parts to develop in the job of raising the self-image.

Today the internet has become a meeting place for people seeking advice and experience from other individuals. Internet also offers opportunities to send out information to large groups of people, which are at a geographical distance. A large increase of websites for parents has been seen in the recent years. On the largest Swedish website for parents, Familjeliv.se, approx. 40 000 posts are posted daily in the discussion forum.

My purpose in this essay is to show how the staff in an institution for young women with a drug addiction, are looking at themselves as "normal" and the young women as "abnormal", and to analyse how sex and gender are made, in interaction with sexuality and class.The essay is based on interviews and a participating observation. The study is made on a compulsory institutional care institution for young women with a drug addict. To analyse the material I use theories by Beverly Skeggs and Judith Butler.In the study I show that the staff in the institution define themselves as "normal" and intend to act as models for the clients, which are described as "abnormal" in terms of being destructive, boundless and sexual. In making class and gender the staffs efforts to make clients learn domestic values and to make their bodies feminine are shown to be central processes. Sexuality is by the staff seen as something happening only between men and women, and defining relations between men and women as always sexual creates gender.A central tension that I show in the essay is that between normal and abnormal, both in relation to differences between the staff and the clients and in relation to the staffs roles as both models of normal life and of violent and violating keeps of order.

AbstractThe purpose was to investigate whether a recovery perspective, viewed from a psychosocial approach is applied in municipal / private and county related care and rehabilitation. A recovery perspective means that the attending staff ensures that the clients are viewed as holistic individuals, where all aspects of life are considered to ensure adequate care and rehabilitation. A questionnaire was answered by staff in psychiatry, social psychiatry and addiction treatment from different areas of the municipal / private and county related sector.The results show no difference in application of a recovery perspective between these two types of organizations. However, there is a slight tendency (non-significant) to lower-rated general individual competencies for municipal / private. There is also a strong tendency (non-significant) to a general difference between the aspects of the implemented recovery perspective, where the tendency is that the respondents as a whole estimate that the organization to a greater degree creates good conditions for a recovery perspective compared to the degree they are actually working on that basis.

Bakgrund: Alkohol- och drogmissbruk är idag ett utbrett problem som drabbar minst 15,3 miljoner människor världen över. Det råder en allmän stigmatisering i dagens samhälle mot missbrukare, bland gemene man samt inom hälso- och sjukvården. Denna stigmatisering har skapats dels på grund av den bild media skapar av den stereotypa missbrukaren och dels på grund av okunskap. Sjuksköterskor hyser ofta fördomar mot denna patientgrupp vilket kan leda till bristfällig vård. Syfte: Syftet är att beskriva sjuksköterskans erfarenhet och upplevelse av att vårda patienter som missbrukar alkohol och droger.

This master thesis describes the development of an UPS module. UPS is an acronym for Uninterruptable Power Supply. The UPS module has been developed at the company AerotechTelub AB. The UPS module delivers the necessary voltage and current in case of a power interrupt. If a power interrupt occur, the computer system has one to three minutes available to store data and shut down correctly.

The purpose of this essay has been to examine whether attitudes and behavior among Swedish people who takes snuff are dissonant or not and how their attitudes are affected by the media debate about the health risks snuff can cause. Furthermore, we were interested in finding out how different reference groups´ attitudes would influence the attitudes and the willingness of people to stop taking snuff and investigate how much control the people who take snuff think they have. To answer these questions we chose to ask primarily students at Stockholm University and Södertörns Högskola. The students were asked to fill out a questionnaire with 22 questions and the 100 responses we collected were worked up in a statistic program, SPSS, on the computer. The main models used for the essay and for the questionnaire were the Theory of Planned behavior and the Dissonance theory.

Forskning visar att flera faktorer i individens miljö och karaktär har mycket stor betydelse när det gäller att sluta med missbruk. Syftet med denna studie är att undersöka hur f.d. missbrukande kvinnor agerade för att ta sig ur tungt missbruk och hur de upplevde det sociala stödet ur ett genusperspektiv. För att fokusera på detta har författaren intervjuat personal om stödet som erbjuds inom frivård, socialtjänst och behandlingshem. Dessutom har författaren studerat vilken sorts stöd som personalen och kvinnorna i studien anser vara viktigast och hur samverkan mellan olika delar av den sociala sektorn fungerar.

Solid waste management is one of the most essential functions in a country to achieve asustainable development. In India, it has been one of the least prioritized functions during thelast decades. The most common ways to treat waste in India today are open dumping anduncontrolled burning. These methods are causing severe environmental pollution and healthproblems. India is one of the world?s largest emitter of methane gas from waste disposal.Since methane is a strong greenhouse gas, even small emissions have large impact on theclimate.

In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential. The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.

The aim of this study is to contribute to a better understanding of the syllable as an alternative to the phoneme at the basic reading and writing. This report is based on a qualitative analysis of Håkanstorp school´s approach to the basic reading and writing in class. Their approach to reading and writing is controversial, as it is based on the syllable instead of the phoneme, as usual in the traditional reading and writing. The education result, I have found, is that the syllable leads to a very clear and structured working procedure, which ultimately leads to class teachers being able to work from a diagnostic approach. This structure, with many parts of the course helps educators to clearly follow what level students are at.
