The real estate company Ihus is facing an expansion of its comfort cooling in Noatun,Uppsala, to provide the buildings in the block with cooling. The buildings in Noatunare mainly used for office premises, where the requirements for an accepted indoorclimate is great. However, it?s uncertain whether Ihus should continue, as currently,producing comfort cooling by themselves using a compressor chiller, or if they shouldconnect themselves to Vattenfall?s district cooling net.The purpose of this report is to examine which technique of cooling is best suited forIhus and their buildings in Noatun. It should also work as a guideline for othercompanies facing the same problem as Ihus.

How the renovation of the vast Swedish existing building stock with renovation needs will be performed is considered as decisive in order to achieve the target set by the Swedish government of reducing the energy use by 20 percent by 2020. Consequently, the challenge of the building sector consists in reducing the energy use in the existing building stock but at the same time ensuring that the indoor environmental quality is improved and the cultural values are maintained.So far, there have been a few renovation projects which strongly have reduced the energy use and at the same time have taken into account the environmental aspects and the cultural values. The main reasons are that there have been few incentives and a lack of routines in order to steer efficiently a ?sustainable renovation?.The participants in a Nordic project on sustainable renovation thought that it would be a strong advantage to link the concept of sustainable renovation to the Miljöbyggnad certification system. Indeed it is trusted by the Swedish building and construction sectors and can provide sustainability targets in order to steer renovation processes.The objective of the master thesis is to show how the Miljöbyggnad certification system could be integrated in practice in the renovation process of Riksbyggen, an organization which administers housing associations (Bostadsrättsföreningar) and build houses.

As a result of the Civil Protection Act, there is an imperative for Systematic Fire Preventive Measures, SFPM. SFPM can be divided in two parts: organisational preventive measures, and documentation of fire preventive measures. The manner in which SFPM is to be conducted is similar to that of the environmental management system ISO 14001. This report provides suggestions how to integrate SFPM with ISO 14001..

Studien har sin utgångspunkt i en trend som blivit allt mer synlig under den senaste tiden; människor tar ett personligt ansvar för globala problem. Studiens syfte är därför att undersöka hur medvetna människor ser på frågan om personligt ansvar vad gäller globala problem? Studien är gjord som en fallstudie och undersökningsenheten, eller fallet, är deltagare på kursen Hållbar utveckling. Metoden är intervjuer. Jag har genomfört semistrukturerade intervjuer med fem kursdeltagare och dessa intervjuer utgör studiens empiriska underlag.

Travelling children is the topic of my work. Children who commute between more than one home. Society is rapidly changing and so is the concept â familyâ . The nuclear family is no longer the most common one. Children are now travelling more frequently than ever.

Samverkan i Kronobergs län bedrivs mellan försäkringskassa och arbetsförmedling. Verksamheten innebär arbetslivsinriktad rehabilitering för individer. Under 2007 presenterade länet ett mycket gott resultat för verksamheten och låg i topp jämfört med övriga län. Därav finns intresse att studera verksamheten. Studiens syfte är att beskriva det samverkansarbete som sker mellan myndigheterna i verksamheten Samverkan och att generera hypoteser som kan förklara de goda resultatsiffror Kronobergs län har presterat.

This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

Background and problem: In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The emissions in the transportation sector have, in contrast to the total emissions, increased since 1990 and will continue to increase unless powerful control measures are implemented. The lorry centres have to use strategies to answer to these external threats which lead us to the two questions of this thesis: - What methods do the lorry centres use actively and which do they consider as the most important methods for fuel saving? - Are there any differences which methods small, medium and large centres considers as important? Purpose: The main purpose of this thesis is to examine which methods lorry centres use actively and which they consider as important for fuel saving.

The purpose of this Bachelor's thesis is to study the reasoning behind classification, cataloging and shelf arrangement of nonfiction graphic novels in public libraries. The aim was to examine which aspects of accessibility influence in which collection nonfiction graphic novels are placed.With qualitative semi-structured interviews we learned how six librarians motivated their choices concerning nonfiction graphic novels. We also interviewed a cataloger from Bibliotekstjänst to examine how nonfiction graphic novels are classified. In our analysis we compared our results to theories and practices concerning alternative shelf arrangements in libraries and legitimization of graphic novels. We found three types of shelf arrangements for nonfiction graphic novels: graphic novel shelf, nonfiction classification code and a mix of the two.

In visual programming the developer specifies her code, using visual tools. Within the range of visual programming languages lay icon-based languages, form-based languages, and diagram languages.Mediator is a multimedia authoring tool that allows the user to create interactive CD-ROM presentations, dynamic HTML pages and Flash projects, without any coding or scripting. The user can create interactivity in her project, using event driven and icon-based visual programming, through a ?drag and drop? user interface. This report intends to determine some of the qualifications of a tool of this kind, as well as its limitations.The report is based on a case study, in which a smaller software application was to be updated using Mediator 9.

Detta examensarbete belyser fenomenet kodväxling som kommunikativ strategi hos en grupp gymnasieelever med svenska som modersmål och svenska som andraspråk, vid samtal på engelska. Med en sociokulturell syn på kunskap och lärande och med språkanvändning som förargument, antogs en samtalsanalytisk inriktning med avsikt att studera form och funktioner för kodväxling. För att belysa det som sker i ett samtal mellan dessa elever och konkret ge exempel på olika former och funktioner för kodväxling genomfördes både en ljud-och videoinspelning med eleverna i två omgångar följt av en transkribering av det inspelade materialet. Det centrala materialet i studien har därför sin grund i transkriberingen och bygger ur metodologisk synpunkt på samtalsanalytiska aspekter som på kommunikativa strategier. Studien visar att deltagarna använde kodväxling för en mängd olika funktioner där målet var att få fram sitt budskap.

Biodiversity is essential for human well-being and it is defined as the genetic variation within species and the variety of species and ecosystems. Biodiversity provides several ecosystem services which are necessary for human beings but there are different threats towards the biodiversity. The biodiversity linked to the forest in Sweden are threatened, about 50 % of the red-listed species in Sweden are associated with forests. This is linked to the commercial exploitation of the boreal forest in Sweden which started 200 years ago. The forestry the last 50 years, with clear-cuts, have contributed to a fragmented forest landscape.

Det är framförallt två övergripande frågor som vi har försökt besvara med denna studien: Hur är situationen vad gäller väg- och tågtrafikinducerade buller- och luftföroreningar i Burlövs Kommun 1994 och hur många av kommunens invånare påverkas av för höga halter/nivåer? Är den översiktliga metoden som vi har valt att arbeta med, i kombination med tillgänglig data, lämplig och tillräckligt exakt för att beskriva den aktuella miljösituationen i Burlövs Kommun?.

The European Water Framework Directive (WFD; 2000/60/EC) was incorporated into the Swedish legislation in 2004 through the ordinance Förordningen om förvaltningenav kvaliteten på vattenmiljön (SFS 2004:660). The objective is that all water bodies shall reach a good status by the year 2015. In Sweden the comprehensive plans of the municipalities can play a large role in reaching these goals. A comprehensive plan deals with the long term water and land use of the municipality, which can facilitate an early consideration of water management in the planning process of the municipality. In Sweden five river basin districts have been established in accordance with the Water Framework Directive.
