The consumer society exploits the earth?s resources more than the earth itself has capability to produce. This over-consumption causes a mass production of products, which mean that more greenhouse gases are being emitted to the atmosphere. This is one of the reasons why the earth?s temperature is rising, where the result of it is worldwide disasters.

Vuxna dyslektikers informationsbeteende en undersökning av hur sex personer med dyslexi hanterar informationsproblem

The aim of this Masters thesis is to describe the information behaviour of six adults with dyslexia with focus on how they handle information problems. The data consists of literature and interviews with six persons with dyslexia. The theoretical framework used in this study is Anders Hektors theory about human information behaviour as well as concepts and theories from the library and information science field. Ten information activities are used to describe the informants information behaviour. Answers are sought to the following questions: · How do the informants describe their backgrounds and their reading- and writing disabilities? · What problems do the informants meet in the context of information in their everyday lives with reference to ten particular information activities? · How do the informants solve these problems? The study showed that the main problems for the informants appeared to be difficulties with reading and spelling, problems with the appearance of the information, lack of time and stress while reading and writing as well as problems with lack of awareness about dyslexia.

Green IS ? a Systematic Literature Review

This thesis provides a systematic literature review of a selection among current papers andarticles on Green Information Systems (IS). The main focus is on the current state of Green ISin academic research. This study aims at gaining a deeper understanding and a clearer view ofthe state-of-the-art of IS for environmental sustainability research, with the goal of clarifyingthe diffuse idea of what Green IT/IS is, and what differentiates Green IS from Green IT.To support the objective of this study, the articles selected for data analysis were collected byusing a systematic literature review as research and analytical method. Within the thesis, adescriptive angle with an interpretative character is used to analyse the data extracted.A theoretical framework based on concepts from sustainability, Green IS and Green IT isemployed in order to analyse and compare terminologies and frameworks used in the studiedarticles. Furthermore, the different dimensions of sustainability and the various terms used todescribe Green IS are analysed comparatively.The result and analysis are discussed in a conclusion confirming the on-going ambiguity ofthe terms Green IT and Green IS and the transformative power of IS.

VVA-strategier för avgastemperaturhöjning på en HD-Dieselmotor

Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.

Digitala objekt i neutralt format

Today there are many different Cad-applications on the market for engineers. Because of big building projects it has become more and more important to work with the same application or to have access to a neutral file type to be able to transfer files between different ones.This report studies the single objects and how they react when transferring them between ADT and ArchiCAD via the neutral type IFC. We have also been looking at problems during the transfer between and if there are some connections between these problems. Afterwards we created a neutral object model of a small country house to see if the objects appeared different. The result shows no differences.But looking at the problems that appeared during the transmissions they felt small and no logical.Today it is not possible to save in a neutral type without facing small problems.

Den ekologiskt hållbara staden : en diskursanalytisk studie av styrningspraktiker i Hammarby Sjöstad

This study focuses on the politics around ecological sustainable development in Sweden today, with emphasis on urban development, building and living. The starting-point for this study is the environmental adapted city district of Stockholm, Hammarby Sjöstad. The primary focus of the study is to investigate what means of control the environmental investment in Hammarby Sjöstad is expressing, and to elucidate their ideological, political and social implications. The empirical material is primarily based up on the local Hammarby Sjöstad environmental program along with qualitative in-depth interviews with citizens of this district. The study is based on critical discourse analysis The result of this study is that the ecological investment in Hammarby Sjöstad partly constitutes a hidden exercise of power, taking shape as built-in physical measures in the dwellings and the neighbouring surroundings.

Energikartläggning av Fridhemsskolan 16:2

Increased energy consumption in the world has created an increased supply of various fuels, especially fossil fuels. The Swedish government has set up various energy targets for 2020. To reach these goals it?s important to increase the energy efficiency in local buildings such as schools. This work illustrates the breakdown between energy supply and energy losses over the school.

Ekologisk slaktgrisproduktion i Sverige :

This literature review describes organic pig production in Sweden, its advantages and disadvantages, but also how its problems can be reduced or solved. Organic pigs have the possibility to a more natural behaviour than conventional pigs. With outdoor pigs comes problems, especially during wintertime, concerning water and feed supply, thermal environment and supervision. Parasites and leakage of plant nutrients are other difficulties that comes with outdoor pigs. All problems and difficulties can be reduced or put right through correct management.

Infallsvinklar och angreppssa?tt fo?r en svensk livsmedelsstrategi : En utredning av angreppspunkter och betraktelsesa?tt hos livsmedelsstrategi-intressenter samt ha?llbarhetsaspekter av dessa.

Understensho?jden is Stockholm's largest eco-village which was built in the early 1990s with the vision of enabling ecological living for people. However the ecovillage is no longer considered as environmentally friendly because of its relatively high energy consumption, and non-updated energy system. The purpose of this study is therefore to investigate how Understensho?jden should reduce their energy consumption and upgrade its energy system by using Blower-Door, IR-camera and Design Builder.

ISO 14063 : drivkrafter och mervärden för miljökommunikation

The enterprises of today are beginning to realize that environmental issues are a important part of their activity. Companies and organizations are expected to a greater extent communicate their environmental work to the world surrounding them in a trustworthy and structured way. Lack of information or information that is incorrect may bring farreaching consequences. Communication is mentioned in several of the ISO 14001-standards. But what is missing is a guideline how companies should act to create and be sure of the quality of the data that can be used in the environmental communication.

Energieffektivisering av Villor : Finns möjligheten till Passivhusstandard för befintliga bostäder

The climate change the earth today has to face is no longer a global problem when every individual has a responsibility to act. The residents in Sweden have no understanding how their energy consumption affects the environment, nor what measures can be taken to reduce the energy consumption.The use of the energy in new Buildings is considerably lower than in the older ones as conditions have improved and the requirements have been more stringent. As most of the buildings in the future have already been constructed it´s important to take every opportunity for energy efficiency and rebuilding of available buildings will become a significant act. Reconstruction of a building contributes generally to both a reduced individual and a reduced total energy use, while new constructions only keep a low individual energy use but a increase the total energy use. For this reason we present the opportunities for reconstruction, mainly to reach the standards for a passive house..

Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos

Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.

Ekologiska livsmedel i kommunal verksamhet : Fallstudie över Ludvika kommuns satsning på ekologiska livsmedel inom skola och äldreomsorg

Organic food is produced in a way that strives towards maintaining and improving natural resources. The welfare of both producers and consumers is central, also taking both animals and the environment into account. The Swedish government finds this important and in 2006 they made a resolution that the consumption of organic food should be stimulated. The goal was that 25 % of the municipalities? consumption of food should be organic in 2010.The municipality of Ludvika reached the government's target in 2011 and is currently increasing their proportion of organic food by one new product every year.  Ludvika is a member of The National Association of Swedish Eco-municipalities and the town of Ludvika is also a Fairtrade city.
