Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Bakgrund: Hälsoutgifterna i förhållande till BNP har i flera länder ökat, samtidigt som vissa länder uttryckt oro över att fokus på utgiftsrestriktioner har skadat prestationerna inom hälsosystemet. Utvecklingen inom den isländska hälsosektorn är densamma.Syfte: Denna studie syftar till att beskriva och behandla de huvudsakliga problem som den isländska hälsosektorn står inför, redovisa åtgärder och reformer som har utförts med tyngdpunkt i privatiseringsplanerna samt diskutera möjliga alternativ för framtiden.Genomförande: Studien genomfördes parallellt med praktik på Sveriges ambassad i Reykjavik, Island. Det har bidragit till att författaren disponerat över ett stort informationsunderlag vilket underlättat förståelsen för specifika isländska faktorer, attityder och levnadssätt.Resultat: Det är viktigt att isländska staten har klara definitioner gällande vilken rättvisa som skall finnas i hälsosystemet. Fondering och ökad prevention samt införande av en resultatorienterad budget samt att staten utformar ett väl fungerande system för kvalitets- och kostnadskontroll för att få till stånd en effektiv privatisering..

Tasmania is a state in Australia, and is also the country?s largest island. It is separated from the main land by a 429 kilometer wide strait. Every year, a large amount of people, cars and goods are transported to the island using a government owned ferry line, which generates approximately 300 million Australian dollars to the state?s economy ,every year. This bachelor thesis investigates the possibility of reducing the fuel consumption for the ferry traffic to and from Tasmania, which would also reduce the overall cost.

Ship formed monuments from the Late Bronze Age on the island of O?land, southeast Sweden, have never been thoroughly dealt with in previous research, despite the fact that the region is suggested to have had a key-role in maritime trade networks. This thesis aims to address the ship formed monuments on O?land in relationship to the monuments in northern Sma?land and the island of Gotland. My goal is to discuss how the ship symbolism was practised during the Late Bronze Age in Scandinavia from a new perspective.

Is the Swedish author Stig Dagerman an existentialist? This work takes a close look at Dagerman?s novel Island of the Doomed to see if it is possible to consider it an expression of existentialist thinking and to see if it interacts with any specific existentialist tradition. Dagerman?s novel was compared with select works of five existentialist thinkers ? Søren Kierkegaard, Martin Heidegger, Jean-Paul Sartre, Albert Camus and Karl Jaspers, all read in the light of the four categories of existentialistic thinking identified by the Swedish scholar Lennart Koskinen. All the four categories appeared to be central themes within the novel and a few subcategories were identified.

This report is a bachelor's thesis of two students from the Energy and Environment degree at KTH Stockholm. Grinda is an island situated Stockholm archipelago. Skärgårdsstiftelsen is landowners and manages the area. Grinda Wärdshus, a guest house located in the island, currently uses an oil-fired boiler as a heating system. The aim of this thesis is to investigate whether wood chips or pellets is, from a sustainability standpoint, a suitable heating method for the guest house.

The purpose of this thesis is to describe and analyse the road towards a modern library in the southern archipelago of Gothenburg between the years 1943 and 1976. The archipelago consists of about thirty smaller and larger islands, of which seven are inhabited throughout the year. Styrsö and the surrounding islands composed a municipality of their own until 1973. In January 1974 it became a part of the municipality of Gothenburg, this is also the year when the only bridge in the archipelago was ready to be taken into use, between Donsö and Styrsö. There is no bridge between the mainland and the islands.

Lotsbroverket is the largest wastewater treatment plant on the Aland Islands and it isdesigned for handling wastewater from approximately 30 000 persons. In 2011,Lotsbroverket produced about 2800 m3 of dewatered sludge. The sewage sludge that isproduced is transported to a contractor where it is processed to eventually be used e.g.in the construction of green space. This study aims to investigate available applicationoptions in terms of the sewage sludge that is produced in Lotsbroverket. The main aimis to study the feasibility of using the produced sewage sludge as a fertilizer in theagriculture of the Aland Islands.The sludge already fulfills limit values for heavy metals in accordance with the Act"The Aland Government´s directive on the use of sewage sludge in agriculture." Inorder to clarify the sludge content of pharmaceutical and organic substances it isrequired that the substances are identified and a risk assessment is performed.

This one-year master's thesis investigates the late part of the Middle Neolithic on the island of Gotland. This thesis has been written without the influence of a singular theoretical pespective, and has therefore seen input from the processual, and postprocessual theories. By using several perspectives, an attempt is made to view the material remains used in the most objective manner possible. The specific aim of this thesis is to investigate whether the Mid-Neolithic inhabitants of Gotland were a part of the Corded Ware culture (or as it is called in Sweden, the Battleaxe culture or the Boataxe culture). Most recent literature has concluded that Gotland was never a part of the Battlexe culture, though this thesis has discovered many parallels with the mainland culture, including the production of similar objects and ritual practices.

There have previously been very few studies of forests on Seram Island in the Eastern Indonesian archipelago and none before on lowland limestone primary forests. The COLUPSIA project on collaborative land use planning has therefore chosen Seram as one of two project sites. The objective of the COLUPSIA project is to establish collaborative and equitable land use planning. In order to achieve its objective the COLUPSIA project aims to improve understanding of traditional resource management and how it interacts with governmental systems, as well as enhancing knowledge about tropical landscapes and ecosystem services.The aim of this study was to contribute to the COLUPSIA project through describing lowland limestone forest on Seram Island in respect to (1) forest structure, (2) tree species richness and (3) tree species composition. We set up 5 plots, each of 0.2 ha, at one site, Mawalai, and collected data on tree variables (tree diameter ?10 cm) as well as for some other life forms and environmental data.

This study investigates how the host community of Tenerife perceives the socio-cultural effects of tourism on the island. The method chosen for the study was qualitative interviews which were performed with six respondents, each born in Spain, living permanently in Tenerife and employed within service-related occupations. The interview material was interpreted and handled according to a hermeneutic approach. The results of the study showed that the respondents had an over-all positive perception of tourism. Perceived positive socio-cultural effects were related to cultural and linguistic influences.

Summary The place I have been working with is a garden, belonging to a family estate, called Tolvmansgården. It is located on an island northeast of Norrtälje in Roslagen. The frontage is red with white corners like so many other houses in the neighbourhood, but ours is one of the oldest houses on the island. Today the house and garden is own by my mother, Pia Johansson. Since I?ve started my education in garden design my interest for our country garden has increased.
