The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

Sara Lidman?s first novel, Tjärdalen (The Tar Pit, 1953), addresses ethical issues in a remote village in the north of Sweden. This essay discusses the novel?s narrative technique and the ethical aspects implied by the narration and aesthetic design. The approach is based on Adam Zachary Newton?s narrative ethics, which links narrative theory and method with an ethical perspective.

Att vi går en värld till mötes som blir mer och mer påverkad av klimatförändringarna är ingen nyhet. I vilken takt eller exakt vilka effekter dessa förändringar kommer att leda till, är osäkra. För att minska konsekvenserna av klimatförändringarna har fokus hitintills, världen över, legat på att minska utsläppen av växthusgaser till atmosfären. Under de senaste åren har dock forskare insett att det blir allt viktigare att även anpassa områden till klimatförändringarnas effekter. Klimatanpassning är extra viktigt i kuststäder, som är särskilt utsatta för havsnivåhöjningar och där även stora socio-ekonomiska värden är samlade.

Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.

Abstract This paper discusses protectionism of intellectual property rights in general and the conflict between large pharmaceutical companies? rights to patent and developing countries? rights to cheap generic preparation in particular. The essay focuses above all on HIV/AIDS medicine. The description tries to give an image of the different interests that collide and why they collide. The different actors are above all the pharmaceutical branch, including researchers, inventors and salesmen with their economic interest of revenue, and the population of the development countries and their pressed situation considering the great need of medicine.

During pre-slaughter handling of pigs the animals are often subjected to methods that induces stress and are a threat to the wellbeing of the animals, such as mixing of groups, loud noise and transportation. A new law will be implemented in 2006 in Sweden that prohibits mechanical noise exceeding 65 dB in abattoirs. The purpose of the research presented in this paper was to examine the effects of noise and transportation on pig behaviour. The activity and aggressiveness of the pigs were examined with behavioural studies during transportation and during three different noise levels: 55, 75 and 95 dB. Before the noise treatments took place the groups were mixed and half of them were transported for approximately 2 hours. In the study 432 pigs were used.

Old industrial sites bear witness of the unsustainable industrial developments in the past. Today many of them stand abandoned and empty, old structures lacking function in our present society. We have in this thesis participated in a visionary student competition arranged by IFLA, International Federation of Landscape Architecture by developing a proposal based on a vision of how Stockholm can stimulate a greener development. We have done this by turning an unsustainable industrial site in the city into an ecological node; Arboretum Lövholmen. Our aim is to develop an entry for IFLA?s visionary student competition by creating a new sustainable design for the industrial area of Lövholmen in Stockholm. We have worked with the following research questions: How can we create a visionary design proposal for Lövholmen that promotes sustainable development with the help of ecological design? How can the competition format be a design tool? How can the working process developing a competition entry progress? The competition demands have shaped our working process and functioned as a platform for the structure of this thesis.

This master thesis deals with steel girders subjected to patch loading caused by concentrated moments. There exist no good methods to calculate by hand the ultimate resistance for this load case. In ?tunnplåtshandboken?, (Handbook for sheet metal, which is published by SSAB), one calculation method is presented. It?s however fairly difficult to use, because of many calculation steps and many graphs.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: The effect of naturally existent beta-glucan in adults with hypercholesterolemia. - a systematic review with focus on the Swedish food market.Author: Ida Edman Hellberg, Frida HanssonSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 01, 2014Background EFSA states in 2010 that there are good evidence that three grams of beta-glucan/day from oat as a part of a balanced diet, has a positive effect on total cholesterol and LDL.Objective Evaluate if there is evidence for primary treatment of lifestyle related hypercholesterolemia with products naturally containing beta-glucan.Search strategyIn February 2014 the databases PubMed and Scopus were used for article research. The search terms used were; cholesterol level, beta-glucan, hypercholesterolemia, oat and barley.Selection criteria Articles, written in Swedish and English, on RCT-studies conducted on otherwise healthy adults with hypercholesterolemia (serum cholesterol >5,0 mmol/L) were included. The intervention product must naturally contain beta-glucan, and an equally product should be retailed in Swedish grocery stores. The control group needed to be supplied with a placebo product and the participants could not be on any lipid-lowering medication.

Today, Sweden has about forty companies owned by the government. These are active on markets with variable competition. Some have been given special areas of responsibility that in a practical notion make them monopolists. The period when most public companies where formed (and with that the following subjection to competition) during the nineties and early 2000's, forced the formerly protected businesses to act on the terms of the open market. Parallel to this development the brand has for the last twenty years evolved into something great strategic importance for the business, including the business-to-businesses (B2B).

Syftet med examensarbetet har varit att genom kartläggning av energianvändningen vid Holmen Paper, Hallsta och framtagning av rutiner lägga grunden till ett energiledningssystem vid bruket. Målet med ett energiledningssystem är att säkerställa företagets ständiga utveckling och effektivisering av energianvändningen. Viktig kunskap som systemet skall säkerställa är bland annat hur man kan förbättra sin andel förnybar energi i processen, var i processen de stora energiförbrukningarna finns, samt hur energiutbytet mellan olika processer i företaget, och utbytet med omgivande samhälle kan förbättras. Energiledningssystemets rutiner har byggts upp med ledning av svensk standard SS 62 77 50. Utgångspunkten har vidare varit att till så stor del som möjligt bygga in energiledningssystemet i de redan befintliga systemen för kvalitet och miljö.

The formulation of visions into practical projects is an important part of the professional expertise of landscape architects. This expertise includes the gathering, structuring, improvement and utilization of knowledge. Project models have been developed to provide tools for the implementation and governance of projects, as well as means of learning, reflection and survey of individual projects. The aim of this thesis is to describe some general project models and their theory, and to describe practical, real-life examples of project models used within landscape architecture. Questions asked are: ? How do the processes of idea to construction in landscape architectural projects lool like? Do project models have a relevance for the mission of landscape architects? ? Is a common project model used within such projects, or is the project model varying depending on e.g.

Horses are by nature herbivores, specialized on grass, and graze during the main part of the day. The horse has neither changed this basic behaviour nor the function of gastro-intestinal tract, when the horse was domesticated by man. A horse on pasture has an even production of saliva and gastric acids. The buffering effect of the saliva makes the pH in the stomach above four throughout most of the day. With abnormal long breaks of eating, the pH may decrease, causing an increased risk of gastric ulcer.

High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.

In present time, more and more people move into cities. Densification of cities as planning policy together with an intensive urbanization, makes urban planners face with the contradictory task of creating a city that is both dense and green. Façade vegetation has been used for centuries, mainly in the form of various climbing plants that with or without supportive structures have spread over facades to give a green impression to the environment. The development of new technology today allows urban planners to use greenery integrated with façades. Vertical gardens offer a larger variety of plants, and at the same time takes advantage of the technological benefits of vegetation in city planning.
