In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.

Emission of nitrogen oxides as well as carbon monoxides is an inevitable result of combustion. A Swedish law "Law of environmental fee for emissions of nitrogen oxides as a result of energy production" (lagen om miljöavgift på utsläpp av kväveoxider vid energiproduktion (SFS 1990:613)) controls the emission of NOx from energy production by a system of fees. The system has resulted in a strong approach toward less emissions of NOx among the energy production plants. High emission levels, today exceeding 52 mg/MJsupplied fuel, leads to costs for energy production companies. This paper examines possibilities to reduce the emissions of NOx by optimization of the SNCR-technique in a biofuel fired heat and power plant.

Organtransplantation är för vissa svårt sjuka individer den enda möjliga behandlingen till ett fortsatt liv. För dessa individer är väntan på organtransplantation av lever, hjärta eller lunga ofta en oviss väntan på en livsviktig operation. Denna väntan innebär en förändring och begränsning i individens vardag och påverkar inte bara individen själv utan även närstående. Detta är en upplevelse få personer kan föreställa sig. Syftet är att beskriva upplevelsen hos vuxna individer som väntar på transplantation av livsviktiga organ; lever, hjärta och lunga.

Bakgrund: En viktig del i att jobba som sjuksköterska är att kunna förse patienter med god omvårdnad. Att jobba i en operationssal innebär att jobba enligt ett tidsschema där de olika yrkesgrupperna ofta jobbar parallellt med varandra för att uppnå hög effektivitet. Operationssjuksköterskor ansvarar för hygien och sterilitet under operation och mötet med en vaken patient blir ofta kort och intensivt. Man arbetar med en patient i gången vilket möjliggör ett personcentrerat vårdande. Syfte: syftet med studien var att beskriva operationssjuksköterskors upplevelser av patientkontakt.

Prostata cancer (PC) är den vanligaste cancerformen hos män i Sverige med 10 000 nya fall varje år. I Sverige opereras över 2000 män för PC årligen. Vanliga sidoeffekter efter operationen är impotens och inkontinens. Kunskap hos sjuksköterskor om hur inkontinens och impotens psykiskt påverkar proststata cancer patienter och hur patienter upplever dessa är liten. Bristande kunskap om detta kan innebära att många patienters problem inte uppmärksammas av vården i tid, som kan innebära stort lidande för dessa patienter.Syfte med studie är att belysa patientens upplevelse av att leva med dem två vanligaste komplikationer, impotens och urininkontinens, efter prostata operation.

Artros är en sjukdom som blir vanligare med stigande ålder och drabbar både män och kvinnor. Sjukdomen påverkar en persons dagliga liv på många sätt och smärta är det vanligaste symtomet. En total höftprotesoperation är den vanligaste behandlingen vilket reducerar smärtan, ökar personens livskvalitet och möjligheter att utföra dagliga aktiviteter. Syftet med studien var att undersöka patienters upplevelser av att genomgå en total höftprotesoperation. Denna studie genomfördes med en kvalitativ ansats och data samlades in med semi strukturerade intervjuer.

The Swedish and Icelandic women's movements, the Support Stockings and the Women's Alliance both had the goal to change their nation's women politics. The goal was to increase the low representation of women in their parliaments and to highlight women issues on the political agenda. The essay shows that the most important reason behind the will to form a party, was a new issue being disregarded by existing parties, although there is a considerable interest concerning the issue amongst society. While a party was formed on Iceland the Swedish equivalence did not occur. Even though only one party was formed, both movements achieved the same results.

The purpose of this paper is to analyse and discuss clinch-nails found at an excavation at terrace II in the Garrison of Birka, on the island of Björkö in Sweden. This type of clinch-nails is common in Viking age Sweden and is usually interpreted as coming from boats. The study will try to show that these types of nails could have been used in several kinds of wooden constructions. It will also show how the nails were made and what kinds of tools were used by the Viking smiths. The study has shown that this type of nails were used in several different types of wooden constructions such as boats, sleds, cart bodies, coffins, Birka's ramparts and buildings.

En ruptur av främre korsbandet leder till instabilitet samt funktionsnedsättning i knäet. Det råder i dagsläget delade meningar om behandlingsmetoderna vid denna skada. Oavsett om skadan behandlas operativt eller konservativt så har sjukgymnasten en viktig roll i rehabiliteringen. Patienter kan själva välja var de vill få sin vård, vilket kan leda till att erfarenheten av skadan ser olika ut mellan sjukgymnaster. Detta kan resultera i att synen på operativ kontra konservativ behandling ser olika ut.

Bakgrund: Hjärtoperationer förekommer över hela världen. Förutom den genetiska faktorn så ökar antalet insjuknanden delvis på grund av välfärdssamhället. Studier har visat att personer med hjärtsjukdom upplever ökad oro vid vardagliga aktiviteter. På grund av oron är informationen som ges till patienter mycket viktig. Syfte: Belysa patienters upplevelser av information inför planerad hjärtoperation.

The State Institution for Education of Feebleminded Girls was one of the two swedish educational institutions established under state management in the 1920s and came to be the starting point for further government operations for the mentally deficient. The purpose of this paper was to investigate the activities of the State Institution for Education of Feebleminded Girls, out of what needs the institution filled in Sweden?s care for the mentally deficient. The institution has tried to be understood from the view of eugenics and the perspective of children that was current during the 1900s first half.To fulfill the purpose of the study, the archives for the State Institution for Education of Feebleminded Girls was studied and analyzed with basis of previous research on Sweden?s care for the mentally deficient and the impact from eugenics and Sweden?s child perspective.The study shows that the State Institution for Education of Feebleminded Girls mostly existed to educate students and adapt them to the community, which the institution did by education, disciplinary interventions and sterilizations.

This scientific essay contains an interpretation of injuries caused by weapons and traumas on the bones from the execution site Galgberget in Visby, Gotland. The site was used from about the 13th century to 1845 AD. The purpose is to examine the injuries and describe them, also to investigate what may have generated them. An important question is what bodily position the individuals had at the time of the injury. The methods presented in this essay can be associated with experimental osteology, also the basic methods such as sex- age- and stature- assessment has been applied where?s possible.

???Information Technology is an essential part of the society today, not least in large ???organisations dealing with sensitive information. An example of such an organisation is the Swedish Armed Forces which indeed is in the need of ways to ensure information security in their Information Technology systems. The means which is used is an authorisation and accreditation process.All Information Technology systems go through a life cycle which includes realisation, usage, development and liquidation. In the Swedish Armed Forces the lifecycle is an authorisation process.

This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.
