AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.

Discussions about the sustainable city are now all over the world and many believe that the solutions are merely technical. But what gives the city its character is what is happening in the public places. It is these spaces that bring the people together. Design is the key to sustainable urban spaces. We must produce public places that reflect our society.

Syfte: Syftet med undersökningen är att testa och analysera teknisk analys enligt en kortsiktig strategi på Stockholmsbörsen under åren 2000-2007. Vi ämnar även utvärdera delperioder med utmärkande egenskaper. Resultaten från undersökningen kommer att jämföras med en Buy & Hold-strategi i syfte att testa huruvida den Effektiva marknadshypotesen i dess svagaste form håller eller inte. Teori: Teorin har sin utgångspunkt i Effektiva marknadshypotesen och Behavioural Finance. Vidare förklaras de tekniska indikatorer som används i undersökningen; Relative Strength Index, Moving Average Convergence Divergence samt Bollingerband.

Syfte: Syftet med uppsatsen är att undersöka effekterna av en omvänd aktiesplit med avseende på avkastning, likviditet och volatilitet. Metod: Undersökningen bygger på en kvantitativ metod och vi har valt att använda oss av en event study. Urvalet består av 15 bolag noterade på Stockholmsbörsens A- och O-lista under perioden 1993-2003 som genomfört omvänd aktiesplit. För att beräkna den icke normala avkastningen använder vi oss av marknadsmodellen. Som jämförelseindex har vi valt Affärsvärldens Generalindex.

This thesis aims to explain the emergence of the Common Foreign and Security Policy of the European Union, and its institutional shaping, by using elements of Neofunctionalism and Liberal Intergovernmentalism.Using Neofunctionalism, the Common Foreign and Security Policy can be explained both as a side-effect of Europe's economic integration, and as a way to maintain the former and the European Union's position as an economic superpower. The institutional shaping is a result of lack of convergence between important national interests. Therefore it rests on a firm intergovernmental base, with rigorously limited use of supranational decision-making.For Liberal Intergovernmentalism, geopolitics and ideology, and to a certain level log-rolling, have played important roles. The reunification of Germany convinced France to form an alliance between the two countries. France, determined to achieve an economic and monetary union, thus offered Germany a political union, including a Common Foreign and Security Policy on intergovernmental terms.

The Bachelor thesis ?Oh, it?s only student radio? is a qualitative study of the Swedish student radio and its members. The study aims to investigate the professionalisation of the radio hosts through Pierre Bourdieu?s theories of field and habitus as well as theories of profession. In order to do so, it?s also necessary to establish the radiostations? perceived role in today?s media landscape by analysing their ambition in relation to other media organisations.

This student report is a literature study about cardiac insufficiency in cats and it is written mainly for veterinary nurses. It is about cats with an underlying heart disease that has led to an incompensated heart failure.It presents a general basis on normal anatomy and physiology, and also how to make the diagnosis, therapy and intensive care.The student report is also about the role of the veterinary nurse during the process of the disease, how to help the veterinarian in the best way, how to handle anesthesia in cats with a heart disease, which factors that can have a significant matter in feeding, and what advices to give to a pet owner with a cat with a incompensated heart failure..

The government regulations for energy use in buildings will be tightened in the future. At the same time the interest in environmental classifications and certifications of buildings is increasing. This has meant a new situation for solar energy. The designs of solar heating systems are often based on experience and/or rules of thumb, rather than calculations and simulations. This thesis examines whether simulation tools, in this case Polysun, are useful in this work.

This report is the result of my examination work in Textdesign at Mälardalen University, Eskilstuna. The purpose with this work was to develop an accessible information material for the target group ?normal bowlers? that gives them the information they need to make their own decision on the lanes, because they often miss a coach during an away game. The focus was to target adjust the material through the theories readability, legibility and reading value, together with the method qualitative interviews. The result became a tested information booklet about how to read a lane pattern paper with additional information within the subject..

Purpose: The purpose of this thesis is to identify and analyze innovative products and services within the telecom industry, letting these findings constitute possible ways for CSPs to innovate the experience of their customers. Methodology: The research in this thesis was conducted from a qualitative approach and data were collected using primary- (expert interviews) and secondary sources (journals, articles, web sites etcetera). In addition, a research design entailing four sequential steps was created to stipulate and illustrate the logic underpinning the methodological process. Theoretical perspectives: The theories are divided in three groups. Background theories ? these intend to capture the problematic nature of the transforming telecom industry, examples of such theories are; value chain theories and ecosystem theory.

Due to the requirement for reduced use of insecticides and the lack of competitive mechanical plant protection, you need a scarification with good result. This is often no problem to perform in normal terrain without technical barriers. However, in difficult terrain with large number of rocks and steep slopes, the result would be worse. The purpose of the study is, that in these areas with difficult terrain, to find out the scarified areas quality, describe the non-scarified areas conditions and find out where the limit is for the use of a traditional disc trencher. Findings indicate that there are usually not the machine that is the limit, but the driver of this.

This paper is a literature study aiming to describe scientists newest theories andknowledge concerning the El Niño and Southern Oscillation. Firstly I have described the?normal? conditions with rising and sinking air in Hadley- and Walker-cells in theequatorial Pacific and from there moved on to explaining the reversed circulation patternsand higher sea surface temperatures (SST) leading to rising air and anomalousprecipitation in eastern Pacific constituting the El Niño phenomenon. My outermostinterest regarding El Niño has been the associated teleconnections, especially in nontropicalareas. I have described the El Niño effect on the Indian summer monsoon, ontropical cyclones and on storms and precipitation on higher latitudes.

Detta examensarbete utreder möjligheten av att bygga ett studentboende med fokus på de tillgänglighetskrav som finns enligt Svensk standard samt specifika materials miljöpåverkan.Byggbranschen har en stor negativ påverkan på miljön när det gäller energianvändning.Arbetet avser att utforma ett förslag i form av ett mer miljömedvetet studentboende samtidigt som det ska vara attraktivt.För att alla lägenheterna ska vara tillgängliga för personer med funktionsförhinder har normal tillgänglighetsnivå använts..

Purpose: The purpose of this essay is to get a comprehensive understanding for the thoughts behind Visby?s sustainable tourism planning. Focus will lie on how far Visby has come in their planning and implementing towards a sustainable tourism development. Methods: This study is preceded from a hermeneutical and constructive perspective. The methods used are induction and qualitative research in the form of deep interviews with four key figures working within Gotland?s municipality and tourism industry.
