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.

Abstract: The aim of this study is to investigate the attitudes towards the labour movement?s strategies, goals and organisational issues in Swedish Miners? Union?s (Gruvindustriarbetareförbundet, hereafter Gruv) paper, Gruvarbetaren 1917-1925.The theoretical starting point is Engels? view on the class state. This perspective turns the question of socialism and the way to get there into an issue of working class power over the state. Another theoretical perspective is the partition of the labour movement into a trade-unionistic branch, seeing unions as financial organisations of interest, and a pro-state one, considering unions as political organisations.During the period investigated Gruvarbetaren was quite radical and advocated a firm class struggle strategy towards employers. Since these were considered unreliable, class struggle was seen as the only way to better the conditions for the working class.

According to the Employment Protection Act, the permanent employment is the main condition of employment in Sweden. Nevertheless, nowadays a large number of employers choose to apply other conditions of employment than the permanent employment in their businesses. The rapid technical development and the demands for shorter perspective investment in companies on the Swedish labour market have started the requirement for a more flexible workforce. On-call employment is one of the conditions of employment that is increasing the most. This condition of employment is adjusted by the parties on the labour market.

This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

Charles Hartshorne (1897-2000) was a religious philosopher. He adopted and developed the cosmologic thinking and concept of God from the philosopher Alfred North Whitehead, he was also influenced by Heidegger, Spinoza and other philosophers. According to Whiteheads religious philosophy Hartshorne claimed that there is a dualistic transcendence within the Godhead. A dualistic transcendence where one unity/transcendence of God is abstract, outside the creation and time and therefore is eternal. The other unity (or transcendence) is inside time and creation and closely in process to it .

Energy Director is a control and measuring system for energy consumption and is part of the product portfolio of E.ON AG for more efficient use of energy, offered to business customers. As of today, the system has only one parameter of control, namely power, and the objective of this essay has been to investigate whether other ones could be added. The emphasis is on the environmental perspective, which is why carbon dioxide has served as an example for this parameter in question.Parallel with the study of Energy Director electricity on the margin, calculations of carbon dioxide equivalents and also the Swedish trade of electricity have all been highlighted. Results indicate that when reductions in energy are made it is endorsed to omit from electricity on the margin rather than some mean distributed electricity, under certain conditions, and in addition the calculations of the reductions should be modified regarding the efficiency of the power stations fuelled by lignite and bituminous coal. Sweden practices trade with the Nordic countries as well as Poland and Germany.

This report is about changes in an organization. Changes is something that every organization sooner or later is bound to do. In many cases the changes leads to problems and conflicts. I have chosen to study one change process in the home help service of the municipality of Bollnäs. The change process I have chosen to study is about changes in the day-to-day work for the employees at the home help service.

It is important that organizations today focus on continuous improvements in order to face the growing competition in the world. A company needs a corporate culture that supports and encourages the employees to be creative and innovative in their work. This is necessary for the company if they are striving towards continuous learning and development within their organization.The main purpose of this paper is to investigate how the culture differences between Sweden and China affect Sandvik AB. We will also study how the company manages continuous improvements and what consequences culture differences have on their work.Our paper is a single case study at Sandvik AB in Sweden and China. We have visited Sandvik in Sandviken to conduct a series of interviews with employees of different position within the company and with dissimilar work tasks.

This Masters thesis aims at investigating how 15-year old girls use the Internet, particularly on their free time, taking a source critical perspective. It includes group interviews. The main question of this thesis was whether there is a need for specific user education. The following four questions were asked: What do they do on the Internet during their free time? In what way do the girls learn how to interact with each other on the Internet? How do they relate to different types of web pages and materials from a source critical aspect? What content do they consider to be relevant in a user education? The study is mainly focused on information use and information behaviour in different contexts.

The research in this thesis attempts to understand what happens when children (3-6 years of age) interact with each other in the context of free play in two pre-school settings when adults are not involved. The aim of the study was to get a closer look at how children create relationships and how they protect and defend their interactional spaces. Data was gathered through ethnographically inspired methodology, using video observation to capture the everyday interactions of the children. Results were analyzed using a phenomenological approach to peer cultures. Previous research suggests that it is very important for children to maintain their interactions with peers and gaining access to play.

The purpose of this essay is to investigate the term equableness in the Swedish elementary school with a take-off point in the free school reform from 1992. This essay starts with the political background of the terms equableness and freedom of choice and the official governmental guidelines. Research from Bo Malmberg and Gabriel Sahlgren act as a framework for the whole essay as their theories are tested. The main problem is presented as the question: is the debated concern regarding a lowered equableness since 1992 justifiable? Both researchers define equableness as a difference in grades but undertake a collective versus a more individual approach.

In my degree project I have chosen to write about the social interactions in children?s play. Iwanted to study their free play and the time when their teachers tell them what to play to seewhat their social interactions look like. The purpose with my research is to study whathappens in the social interactions in their different playing situations.I performed three observations of the free play and three observations of the guided play at apreschool to study what social interactions that takes place in the different playing situations.What happens and what patterns can I find in their play.In my research I had some questions that this project rests upon:What happens in the social interactions in the different playing situations?How do the children?s different social interactions look?The children that I have observed showed me that when they are interacting they especiallyuse their cognitive abilities, because an interaction needs a certain mental development.

Det är vanligt förekommande att företag låter sig leverantörsfinansieras med handelskrediter. Den internationella forskningen är omfattande rörande vilka egenskaper och förhållanden sommotiverar leverantörsfinansiering. Syftet med denna studie är att visa vilka faktorer som är bestämmande för användandet av handelskrediter i svenska små och medelstora företag. Undersökningen inriktas på att studera vilket samband lönsamhet och skuldsättning har till handelskrediter. Företags ålder och storlek studeras också i förhållande till handelskrediter.Studien genomförs med en multipel regressionsanalys där den beroende variabelnhandelskrediter representeras av leverantörsskulder.

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.
