The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

This master thesis is written at the Royal Institute of Technology during the spring and summer of 2008.The assignment was to investigate what factors on a broadband market determine how well it performsin terms of how many people have access to broadband. These are the factors that determine whetheror not a country or market will be able to achieve a high broadband penetration. The purpose of thisthesis was to establish a better understanding for what a market should look like or how a strugglingone can be complemented in order to succeed.As a foundation for this investigation, a group of benchmark countries were chosen and evaluated. Inaddition to this, a group of, developing MENA2-countries were chosen and evaluated. Finally, interviewswere performed with some of Sweden?s leading internet service providers, the regulatory agency andinfrastructure company, Skanova.Among the benchmark countries were Sweden, France, Canada, South Korea and Japan.

The purpose of this Master Thesis is to investigate whether the technical service available in the "Reading and Writing Corner" has an influence on the total quality of service in a public library. This service is intended to give sensory/print-handicapped persons access to information. The title KOM LOSS is a Swedish expression for "come on" and LOSS is short for reading and writing support. I have chosen to study three libraries in the region of Västra Götaland, Sweden. The thesis examines total quality from the aspects of goal steering, accessibility, education and marketing.

Tången 2 is a building situated in Stockholm, Sweden. It´s built in the 1930s and contains both residences and businesses. The property owner, Diligentia AB, wants to lower the energy use in Tången 2. This report consists of an energy audit which clarifies the specific circumstances linked to Tången 2. Collected knowledge is then used, together with the results from the literature study, to decide energy measures to proceed with.

Background: The Swedish Police authorities have accomplished several changes the last years. We have studied one of these changes, the co-ordination of two supporting functions, economy and staffadministration at the Police authorities in Östergötland, Jönköping, Södermanland and SKL (Swedish crime technical laboratory). The initiative to this change was taken in 2002 and in 2003 a decision was made to create a joint servicecenter.Purpose: The purpose of this rapport is, in a collaborator perspective, to study the employees´ experiences of the change process.Method: The empirical material was collected throw interviews with the employees who have taken part in the change process. Even the leader of the project has been interviewed.Results: We have distinguished five central aspects in the change process. These are information/communication and understanding, the project leader, teamwork, timeaspect/reflexion and the leadership.

We live in a stressful world and a demanding society where the ability to quickly adapt is one of the most important and most difficult challenges of today. A fairly new phenomenon called intranets has evolved to meet this challenge, however many examples of corporative intranets are stories about failures and systems with poor usability. This study focuses on how the user oriented approach to systems design affected upon a system development process of an Intranet, solely developed within a company, and how it impacts on the intranets popularity among the employees in the company. The study starts not from the literature but from a survey, which is based upon the Delphi method. Which results were used for further in-depth research about the subject, by interviewing three representatives from the company.

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

Mast cells have for a long time been known to accumulate around tumors (Maltby et al., 2009). Studies show that they may be important and sometimes essential in tumor angiogenesis, tumor growth and metastasis of tumors (Soucek, et al., 2007; Xiang et al., 2010). In an expression array study (Wensman et al, submitted manuscript) performed on mouse mast cells exposed to tumor conditioned medium, the gene 4-1BB was among the most up-regulated genes compared to control medium. 4-1BB codes for a membrane receptor protein of the tumor necrosis factor superfamily and has been shown to be important in T cell regulation in tumor diseases. This study was performed to investigate if human mast cells up-regulate 4-1BB when they get exposed to tumor conditioned medium.

The purpose of this thesis is to examine how two separate museums have realised the task of digitizing their collections, as well as to learn what options, possibilities and resources have been available to them during this process. Additionally, the aim here is to find how the two museums have dealt with problems in connection to the digitization projects, since there are as-of-yet no established regulations or standards to guide them in their digitization efforts. However, national and international working groups seeking to establish better collaboration between archives, libraries and museums ALM institutions have recently begun to formulate recommendations and suggested standards. Some of these recommendations have been used here as a theoretical framework in the examination of the two museums. The research questions posed are: What options, possibilities and resources have been available to the museums in their digitization projects, in terms of economy, staff, technical equipment and time?; For what purpose are the museums digitizing their collections?; and How does their purpose influence the process and chosen procedures? Also discussed here is how the museums relate to some of the existing recommendations.

Abstract In the contemporary world of information technology you find a multitude of applications and systems covering a broad spectrum of areas of need in different companies. One effect of this multitude of programs is the difficulty to make them exchange information with each other or to collaborate, since they are developed by different programming languages for different platforms, with different standards and different data formats. Our aim with this work is to describe how it is possible to tie these programs together to make them actually communicate with each other in order to exchange information, share their native methods and also to become a part of the overall business processes. In this integration task you will, among other things, find different levels of application integration such as data level, method level, application interface level and user interface level integration. Application integration also involves hardware components, called middleware, that facilitate the physical connection between applications.

Syftet med den här studien var att undersöka hur pedagoger anser att de arbetar med IKT, information- och kommunikations teknik, i förskolan. Syftet var även att undersöka om pedagogerna på något sätt skulle vilja utveckla arbetet med IKT. I denna studie riktas intresset in på surfplattor. Metoden som använts för att få svar på undersökningens frågeställningar är kvalitativa intervjuer, intervjuerna har genomförts med åtta pedagoger från två förskolor. I resultatet av studien blir det synligt att pedagogerna arbetar på olika sätt och att de har olika visioner om hur de vill utveckla arbetet med dessa surfplattor. Resultatet visar att alla medverkande pedagoger i studien använder surfplattan som ett verktyg för att utveckla barnens språk, det ser däremot olika ut bland pedagogerna hur den används till exempel för dokumentation och spel med mera.
