This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

The aim of my thesis was to do a Life Cycle Assessment (LCA) of an average thread tap that is manufactured by Dormer Tools AB, and to create a practical model that the company can use in order to study other thread taps from an environmental perspective.The method of LCA is used to investigate the environmental effects of a product during its life cycle. This is a gate-to-grave analysis with focus on steel and thread tap manufacturing, coating procedure, use, waste management and transports. Three common coating types were compared separately. Steel manufacturing answers for the highest energy and raw material consumption under the life cycle of the thread tap. Its emissions contribute to global warming, acidification and eutrophication above others.

Sweden has an environmental goal to achieve until the year 2020. To achieve this goal the construction business has to take an initiative to use the modern techniques that are available to lower the energy consumption I buildings. There?s also a debate going on today regarding the energy demands set by the Swedish government through Boverket, some communities throughout Sweden thinks that the demands are to low and have therefore set up own demands regarding energy in buildings.The possibility to construct energy-saving buildings is today very great, with energy-efficient heating-systems and dense climate envelope. The interest to raise energy-efficient buildings have also increased as a consequence that the population have become more aware about their impact on the environment.

Studenter är bland de som konsumerar mest alkohol i Sverige. Hög alkoholkonsumtion och extern akademisk locus of control (ALC) har liknande negativ effekter på studier. Denna studie undersökte relationen mellan alkoholkonsumtion, ALC och alkoholrelaterade studieproblem. 120 studenter, varav 91 var kvinnor, deltog genom att besvara en enkät bestående av The Academic Locus of Control Scale for College Students, the AUDIT Alcohol Consumption Questions och en egenkonstruerad skala som mätte alkoholrelaterade studieproblem. Data analyserades med en 2 (riskbruk/ickeriskbruk) x 2 (extern ALC/intern ALC) ANOVA för oberoende mätningar.

Emissions of insufficiently treated wastewater, mainly blackwater (i.e. wastewater from toilets), contributes to the eutrophication of lakes and seas. At the same time, blackwater is a fraction with a low content of heavy metals and, after sanitization, it can recirculate plant nutrients to arable land using the liquid composting treatment method. Liquid composting means that organic material is degraded under aerobic conditions. For sanitization, the blackwater needs to be treated together with energy-rich complementary material.

Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter. The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not. The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.

The regulations for energy consumption are consistently getting more and morestrict. This leads to a higher customer demand for energy analysis early in the buildingdesign process. Many building planners and architects use powerful modeling softwareto visualize their projects. These digital models contain sufficient information aboutthe building?s physical characteristics for reliable energy analysis.

The construction industry has demands on energy use in permanent buildings. How much energy that is permitted to use during the time the building is produced has no requirements. The purpose with this study is to learn how far Skanska has come with the work of making the building site more energy efficient.A literature study has been performed in the beginning of the study to survey what energy efficient arrangements that can be applied and how they operate. Using site visits and interviews the situations on the building sites have been studied as well as the energy efficient measure that are in use.Skanska has come a long way with the work of energy efficient building sites and they keep improving. They have improved half of their cabins so they use 50 % less energy.

In this paper we have studied how young adults read news on the internet. The purpose was to seehow the consumers of news were irritated by the adverts on news sites depending on whichplatform they used, a computer or an portable reading device of the brand Apple iPad. Observationsand surveys were conducted on ten people. The news sites we used for this study were www.SvD.seand www.expressen.se. The result show that a majority experienced that their news consumptionwere irritated by advertising, mostly on Expressen's news site because it wasn't perceived asforeseeable..

This thesis in Art History and Visual Science is about values to graffiti and graffiti artist Banksy. I have studied values relating to Banksy´s graffiti images through which context they are placed in and where they are located. I have selected two different images of Banksy as an example on the basis of a transnational phenomenon, where the images that circulate in the public arena by street art and other images and imported into the galleries and consumption market. My conclusion is that the values of the images are based on the context in which each room have its surroundings and that therefore the impression will increase. The public space context, signal availability and the white cube context indicates art, and the commercial context signals goods and items that can be bought.

The purpose of this essay has been to examine the public`s view of the Swedish eldercare during 2006. This study uses discourse analysis as a research method, the reference material has been articles from the newspaper Dagens Nyheter. The aim of the research has been to find central themes, conflicts and consensus in the discourse of eldercare. The analysis resulted in four main subjects which were based on four main questions; the questions of responsibility and execution, the question of contents, and the question of where the eldercare should take place. The analysis of conflicts and relations of consensus in the discourse of eldercare resulted in two different main views; the traditional and a more modern.

This master thesis work was done at Saab Underwater Systems AB, a company at the cutting edge of underwater technology. Here torpedoes and other underwater vehicles are developed and manufactured. The major customers are navies of different countries, mostly the Swedish navy. The aim of this master thesis is to develop, construct and evaluate an automatic Trim System for Unmanned Underwater Vehicles. The task of the system is to change the position of the centre of mass and the vehicle?s total mass or volume.

Museums are a part of the cultural sector that over the last couple of years had to compete with the steadily growing consumption of spectacles. New techniques to attract and amaze the visitors have evolved. Living History Museums has developed a method to simulate past times by building up an environment with reconstructions. History is a non-definite science, there will never be an exact answer to how it really was, for example during the Middle Ages.This essay deals with the difference between reconstructions and authentic artefacts and how they build up an illusion of the past. In what sense does it matter if the artefacts are genuine or not? How do these museums deal with anachronistic phenomena from today's modern world in the historic environment? Additionally I discuss whether or not these reconstructions - of environment, buildings and personal characters - have any influence on the historic narrative given by the museum.

AbstractThe aim of this Master thesis is to explore why some Swedes want to consume?eco-friendly? and whether this fact gives rise to articulated information needs. Two possible explanations for this ?eco conscious? consumption are being tested, either if it is based on a normative belief that it is the right thing to do if you, as a consumer, want to do something about the environmental degradation, or that it is a reaction to a perceived risk, due to the environmental degradation. The method chosen by the author in this thesis is a qualitative text analysis of five Swedish journals.
