Effektiviseringspotential inom industrisektorn : Energibesparing vid frekvensstyrning av centrifugalpumpar ? en fallstudie
The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..
Kartläggning och effektivisering av lastbilsflödet mot ryska marknaden : En studie på Scania AB
This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.
Speaker Park : om ljudsättning av utemiljöer
This project will search for the sound in the contemporary landscape architecture, an attempt to combine music and landscaping. In a first stage, I have searched for outdoor environments where loudspeakers are used, and sites with a concious sound design. The project will result in a sound design created for the park Frodeparken in Uppsala, Sweden.
In my search for sites and examples of conscious sound, I have talked to the people behind the projects I found - landscape architects, sound artists and architects. Influences from different areas have been essential for me in the project.
Green-urban balance : a proposal for balancing green area preservation and urban development in the city of Uppsala
Rapid urbanization causes competition over land use between green area preservation and urban development in cities and greatly affects ecosystems as well as human well-being. This conflict is significant all around the world as many cities are now replacing existing green areas with new developments. The area around Dag Hammarskjöld's väg in Uppsala is currently experiencing the same conflict, as the need that the city has for new housing represents a threat for the many valuable green areas that are in the site. The purpose of this project was to understand how the need of urban development and the preservation of green areas could be balanced. This understanding would thereafter be used to make a design proposal for the area around Dag Hammarskjöld's väg.
Den mobila prefabriceringsfabriken : Ett nytt produktionskoncept
This is an investigation of a mobile prefabrication factory´s competitiveness and profitability which also will result in a suggestion for a design of the factory. The mobile prefabrication factory is an idea of a new concept for production which is meant to be used in the manufacture of slab. The main intention with this concept is that by using a fast established prefabrication factory to produce elements near the construction site, thus avoiding transport from the factory to the building site. This means not only an environmental and economic gain, but also that you can avoid risking damage the elements which often occur during transportation. The contractor is owner of the mobile prefabrication factory and can thus avoid long waiting times and cyclicality.

Verktygsanvändning som miljöberikning för gulbröstad kapucin (Cebus xanthosternos)
That animals should be able to express their natural behaviours, even in captivity, has become a more important issue lately. Nowadays Zoos work much more with educating people and helping conservation projects for endangered species. This is two important reasons for making the environment as natural as possible for zoo animals. Both in captivity and in the wild capuchin monkeys have been seen to use tools such as stones and sticks to get food and are therefore seen as a natural and important behaviour for them.
This study was carried out to evaluate a specific sort of environmental enrichment where a group of three capuchins had to use sticks to get different kinds of food out of bottles.
Kunskap som process eller produkt? : En kvalitativ intervjustudie om dokumentation i förskolan
According to the curriculum for the Swedish preschool system, children?s development and learning should be documented and analyzed in order to evaluate and develop the preschool quality. Social criticism is directed to some of the methods of documentation for assessing the children´s individual knowledge development. The purpose of this study was to examine how, what and why some teachers use documentation in preschool. I wanted to examine which methods preschool teachers used when they documented the children and what they focused on.
"Det handlar om att hitta rätt bok till rätt person vid rätt tillfälle": En undersökning av läsfrämjande verksamhet för ungdomar i åldern 13-19 år.
The purpose of this Masters thesis is to investigate librarians views on reading and reading promotion for young people. The main issue is if activities in reading promotion for people between the ages of 13-19 years can result in inspiring non-readers to actually become readers. To find the answers, qualitative interviews were held with eight librarians. The literature review covers research on the reasoning of young people on reading, a historical review of fiction and reading, a review of arguments on the benefits of reading and finally a chapter which concerns reading promotion activities. The result of this study showed that the conceptions of reading promotion and book talk are very complex and that they each can have different meanings.
Medverkan och inflytande : om brukarnas roll i socialtjänstens kunskapsutveckling
The main purpose of this essay was to study the program "Nationellt stöd för kunskapsutveckling inom socialtjänsten" ("National support for knowledge development within the social services") from the National Board of Health and Welfare on the basis of how such a development, as represented by the program, could affect clients' possibilities to participation and influence within the social services.To respond to the purpose I used the following questions at issue:* How is client participation and client influence defined in the program?* What arguments for and/or against client participation and client influence are stated?* Which patterns and similarities/differences are possible to discern between the municipalities and universities that participated in the program when it comes to client participation and client influence?The study was conducted as a document analysis. I studied documents from the program both on a national and a local level. The essay uses empowerment theories and theories concerning client participation and client influence. The main conclusions were that on the national level the authors of the documents spoke with caution about their view on client participation and client influence and expressed that it had to be balanced against the rights of the citizens and the social workers for example.
En studie av fenomenet mikronationer
ABSTRACTBachelor essay in political science by Hanna Richter, spring 2006Supervisor: Mats LindbergTitle: A study of the phenomenon of micronationsThe purpose of this essay is to study the phenomenon of ?micronations?, to describe it to the reader and to discuss why this phenomenon is interesting to study in the field of political science. The questions this essay seeks to answer are:- What are micronations, and which variations are to be found within the phenomenon?- Why are micronations interesting to study in the field of political science?Bary Buzans theory of the nature of the state works as a frame of reference to this investigation of micro ?state-like? units. The phenomenon of micronations has not been investigated by the social sciences in any extent worth mentioning yet.
Att göra demokrati : En kartläggning av forskningen om Botkyrkas demokratiarbete
By studying a place or a phenomena research contributes to the creation of the image of the thing that he or she studies. Also, planning is seen as a democratic tool, a way to ?make? democracy. In order to see what democratic ideals that is being express it becomes important to study the research about democracy in Botkyrka. It is from this thinking this study about democracy and research has been formed.
En godnattsaga för demokratin? En undersökning av ett läsfrämjande projekt i facklig regi
The purpose of this master thesis is to show how a chosen actor in form of the Swedish union organization IF Metall (the Swedish union for metal- and industrial workers) works with pro-reading activities. The project being scrutinized is the Read to me dad-project which aims at fathers who are not used to reading activities within the LO-group (the Swedish Trade Union Confederation). The methods used are interviews and literary studies. The theoretical background of my discussion is based on three education ideals. The neo-humanist ideal emphasizes the personal improvement through literature.
Google digitaliserar bibliotekssamlingar En analys av hur biblioteksvärlden reagerar på Google Book Search
The wide spread of the Internet and new information technologies in recent years has come to effect how libraries manage and disseminate information. Search engines like Google are widely used by people who often find the information retrieval systems of libraries to be too complicated. In 2004 Google announced plans to digitise five major library collections. Organisations representing the publishing industry and authors have since then filed lawsuits against Google claiming that Googles scanning of library books infringe the rights holders copyright. Due to Googles potential impact on libraries this thesis aims to examine how Googles digitisation project, Google Book Search, has been received in the library community.
