The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.

The aim of this study was to describe how male social workers who work in the section for children and family in one municipality in southern Sweden, experience that their gender influences their daily work. The main focus is to understand what it means to be a man in the social services department. The first research question was how the male social workers experienced how their gender influenced their contact with children and parents in terms of possibilities and obstacles. The second research question was how the male social workers experienced how their gender influenced their working place in terms of possibilities and obstacles. The third research question was how the male social workers experienced that their gender affected the work with women colleagues.

The concept of sustainable development is a challenge that demands cooperation from all levels of society for it to be successful. The focus for this thesis is how politicians within the local councils understand the concept of sustainable development and how they implement it in political decision-making.The basis for the study is a questionnaire that was distributed to 303 local politicians in three municipalities of varying size in Southern Sweden. The study concentrates on departments within the local councils that are directly connected to the Swedish environmental law and the Swedish planning and construction law. One of the primary goals with the aforementioned laws is the achievement of sustainable development within one generation.The outcome of the study was that over half of the local politicians could correctly define sustainable development according to the World Commission on Environment and Development?s (WCED) definition.

The aim of this study was to acquire a greater understanding and knowledge about how care staff at houses with special services for people with intellectual disabilities think and work (handle situations) regarding sexuality. To achieve our goal we carried out nine semi structured interviews using an interview guide. These interviews took place in two different communities in southern Sweden. The theoretical perspectives that were used to analyze the result were Sense of Coherence, Scope of action and Normalization. The result showed that the staff considered sexuality a part of their work and a natural subject to talk about.

Studien ämnar undersöka huruvida backpackers på Khao San Raod i Bangkok, Thailand, etablerar nya kontakter med andra medresenärer. Syftet är att utifrån begreppet socialt kapital undersöka varför relationer initieras samt varför vissa relationer bibehålls men inte andra efter avslutad resa. Då samhället består av kluster som bildar nätverk utgör varje kontakt en resurs. Hypotesen är således att kontakter etableras eftersom de kan ge tillgång till resurser individen annars inte kommer åt.Uppsatsen har huvudsakligen en kvalitativ, teoriprövande design även om inslag från andra ansatser förekommer. Semi-strukturerade intervjuer har ansetts fördelaktiga som datainsamlingsmetod då deltagarnas egna tillskrivna mening ligger i fokus enligt kvalitativ tradition.

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.

Background: In today's Swedish health care, it is required that the various professionals must work together in teams to safer care. Several professionals with various skills expected working together in the traumateam at the care of the traumapatient. At the same time, research shows that substandard teamwork leads to avoidable errors in care. One way to improve teamwork is to practice. Purpose: The purpose of this study is to shed light on the experiences of the traumateam exercises that exercise participants feel has been favorable for the patient at the initial care of trauma patients.

The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

AbstractAs a young offender in Sweden today you can be sentenced to juvenile care within the social services. Within the juvenile care it may be an option for these young offenders to undergo an affect program. That is a collective name for several types of structured programs that can include everything from conversations to visits. The purpose of this study was to create an understanding of which arguments there are for why these affect programs for young offenders is being used in three municipalities in southern Sweden. We authors found this interesting because of the lack of evidence for these affect programs.

The thick shelled river mussel (Unio crassus) has a fragmented distribution in southern Sweden. It is a threatened and protected species. In both the Swedish red list and the IUCN Red List of Threatened Species Unio crassus is classified as Endangered (EN). Causes for this classification are for instance differentiated bottom substrate and deterioration in water quality. In this study, habitat preferences of Unio crassus were investigated to assist in future restoration work.

Communication is essential for the survival of an organization. The management formulates strategies to ensure thatthe organization will get to where they want it to go. The strategy is then communicated to the co-workers through the line manager. But who is to say that the co-worker experience the message the same way as the line manager or the management for that matter? The purpose of this study is toinvestigate how the middle managers at Southern Älvsborg Hospital experience strategic internal communication andfurther how they communicate with their co-workers.Through a case study approach, the case being the communication of the hospitals research strategy, I conducted 13 interviews.I analyzed the material from the interviews using a hermeneutical approach and I used an interpretative approach to get a deeper understanding.

The essay's aim is to explain how responsibility distribution between private and public bodies, primarily within three important service areas, can be visualised in light of the fact that they have experienced different forms of readjustment. We have chosen to study this by looking at the restoration work taking place after the hurricane Gudrun swept across southern Sweden on January 8-9, 2005; and we have chosen to concentrate on the service areas of electricity- and telephone supply, and public transport. The responsibility distribution has been depicted by carrying out qualitative interviews with employees within both private and public bodies included in the restoration work. The conclusion produced is that there were obscurities in the formal responsibility distribution between private and public actors taking place in conjunction with the hurricane restoration work.In a deeper analysis, the result can be explained by a ?several hands? problem arising since the number of actors has increased as the public sphere has adopted leadership forms influenced by the private business sector.

Denna uppsats behandlar en grupp burmesiska flyktingar och deras olika vägar till användandet av det svenska språket för att läsa och skriva. Syftet är att få veta lite mer om hur de som vuxna lär sig ett andraspråk och vilka strategier de med fördel använder vid språkinlärningen.Undersökningen har genomförts med hjälp av intervjuer som spelats in på minidisk och sedan transkriberats. Hela materialet har sedan sammanställts schematiskt och därefter analyserats med hjälp av teorier om språkinlärningsstrategier.Utifrån sin bakgrund i Burma och i Thailand berättar informanterna om sina tidiga läs- och skriverfarenheter. Flera av dem har gått så kort tid i skolan att de med svenska mått mätt knappt har en funktionell litteracitet vare sig på modersmålet, karenska, eller på det officiella språket, burmesiska. Det är dock viktigt att ha i åtanke att kraven på läs- och skrivkunskaper inte är lika omfattande i hemlandet som här i Sverige.

The aim of this thesis is to study and analyze a village in the southern of Sweden called Gnosjö, which is famous for a special spirit of industrial success and entrepreneurship. Gnosjö has been successful and famous for many years but is now standing in front of several threats, like a growing number of out moving inhabitants, a low standard of education and difficulties for women to make carrier. Trying to reduce the threat of young inhabitants moving out, a new education program started three years ago with the purpose to make young students to be more interested in the technical development of the industry and make them stay in the district and hopefully be entrepreneurs.The research questions are; which consequences does ?Entekprogrammet? and the background of the students have on the students view on the spirit of Gnosjö, carrier in the local industries and wish of staying or moving from Gnosjö. Furthermore, I want to see if there are any differences between the girls and the boys, does sex have an influence on the view at the future? The study is made by qualitative and quantitative method.
