This thesis examines different methods for the cooling of data centers. Several means of cooling with the refrigeration cycle have been studied, as well as the feasibility of using free cooling in different parts of Sweden. In addition, the possibilities of transferring excess heat to a nearby district heating system were investigated. It was found that in all investigated cases except two, the data center could be cooled solely with free cooling for at least 300 days a year when only the outside air temperature was considered as a constraining factor. The limit was then set to 20 °C.The vast majority of all district heating systems in Sweden get little to none of their heat from other excess heat sources.

The flagellate Giardia intestinalis has been known to cause diarrhea in both man and dog. Results from epidemiological studies have indicated that transmission of the parasite from dog to man is plausible even though that route of infection has yet to be shown. Several international studies have shown that the parasite frequently occurs in asymptomatic dogs. In Sweden the prevalence of Giardia in healthy dogs is not known though. In this study, faecal samples were collected at two separate occasions from 21 litters and 21 bitches showing no symptoms from the gastrointestinal tract. The samples from each litter were pooled but the samples from the bitches were analyzed individually.

The study focuses the context of a Swedish national multi-sport event hosted and held by three different cities, three different years.

The purpose of this paper is to contribute to a deeper understanding about the acceptance of wind power. Our basic assumption is that local conditions are important and can explain how the acceptance of change at different stages of establishment. The main purpose is to see if there are differences in the acceptance of wind power in different stages, and examine the factors that influence acceptance. That includes how people in three different areas of study estimates that they value their environment and how it is affected by wind turbines. The project was conducted interdisciplinary geo-targeted and consists of three parts.

In this thesis, the introduction of smoke-free restaurants and bars in several EU Member States in a policy convergence perspective is studied. The thesis sets out to explain whether policy convergence has occurred and the possible explanations connected with it. It is stated that 15 out of 25 EU Member States had introduced or decided to introduce smoke-free restaurants and bars up to April, 2006. Out of all the countries in the world, 35, including the EU Member States, had introduced or decided to introduce smoke-free restaurants and bars. The result is analysed by using policy convergence theory and by putting the case in a global environment where tobacco control has become an ever more central theme for public health policy.The EU Member States are different in several ways considered to be important factors for policy convergence, such as cultural, institutional and socio-economic similarities, and the conclusion is made that EU membership has been a most crucial factor for the rapidity of the policy diffusion.

Problem area of this Bachelor thesis is the mental illness of internationally adopted at the age of 16-26. Our study focuses on a compilation of previous results from positivistic researches in the first question formulation. In the second and third question formulations a narrative text analysis, through hermeneutically interpret risk and prevention factors, is carried out for the life of internationally adopted that can lead to mental health/illness and how they apprehend to be adoptees. The purpose is to get a comprehensive understanding at individual, group and society's view of their lives. Further intention is to interpret the material for possible approach angles on further research.

The usage of visions and strategies is something that helps an organisation to create an imaginary scenario and guide them of how to realize these goals. During the years of 2006-2008 Region Gotland presented a document that was supposed to show the region's visions. The theoretical framework of this thesis is based on the stakeholder theory, Balanced Scorecard (BSC) and Management Control Systems Package (MCS). Personal interviews were conducted within the organisation Region Gotland, with individuals whom are directly linked to the visions and strategies of the organisation. The purpose of this study is to clarify the concepts of vision and strategy, and what their impact is on the organisation's work on the operation level.

Examensarbetet har utförts vid ABB Power Transformers i Ludvika i plåtverkstaden, där stora transformatorlådor svetsas ihop. Tillsammans med vår handledare på företaget utformades ämnet för examensarbetet att bedöma luftkvalitet och arbetsmiljö vid punktsvetsning i koppar. Det fanns misstanke om att exponeringen för koppar var hög och en utvärdering av luftkvaliteten behövde därmed göras. Ingen tidigare exponeringsmätning vid svetsning i koppar har genomförts i plåtverkstaden. Syftet med examensarbetet var att utvärdera och komma fram till tre åtgärdsförslag för att skapa en bättre arbetsmiljö vid punktsvetsning samt att begränsa exponeringen av svetsrök som bildas vid svetsning i koppar. Tre åtgärder var företagets önskemål.

The difference between the public sector and the private sector in Sweden was once very small. These sectors have been united as well for the people, the organizations as for the finances. During the 1960´s and 1970´s the public sector in Sweden was expanding and after the 1980´s the people started talking more about an expanding private sector instead. The year of 2007 Hökarängen Hemtjänst Ekonomisk Förening submitted a tender to Äldreförvaltningen about a purchase of the home- help service in Hökarängen and they accept there tender.Exposing public organization for competition can be a good way to make sure that most value for the money is created and that it generates the most cost- effective organizations. The motivation factor is used to describewhat makes people perform more than what is expected of them.The purpose of this study is to describe and explain similarities and differences in working- motivation between those how are members of Hökarängen Hemtjänst Ekonomisk Förening and those how are not.

The Swedish sports retail industry has experienced extensive growth during the last decade, and this has attracted new entrants to the market, both start-ups and international followers. This has inevitably put more pressure on incumbents, which are now confronted with major challenges as how to retain their customers and market shares. Customer loyalty has been proved to be an important factor for customer retention and proposed to constitute inertia of switching behavior. In light of this problematization, the purpose of this study is to describe the underlying factors of loyalty and whether purchase habits could further explain customer loyalty. The aim is also to understand the strategic implications of the factors involved.

This thesis examines the tendering process from the point of view of Swedish building contractors. The purpose with the study is to chart the decision process for the contractors during the tendering process. The study is designed as a survey study. This made it possible to reach a wide base of respondents, not letting such factors as geography being an issue. The survey itself was characterised by a very high response rate compared to other similar studies. The result from this study shows that former experience from similar projects, current workload and the clients economic condition are very important factors for both whether or not the contractor will bid for a project as well as the cost estimation and tendering price. Former experience from similar projects is also an important factor for the determination of the indirect costs.

In this essay the author has chosen to analyze the similarities and differences between some of the northern Europe?s late Mesolithic and Neolithic cultures.

The material collected has been analyzed in both a processual and a post-processual manner to most accurately study the foundations of the three primary theories describing the Pitted Ware Culture?s origin.
