Att möta utmaningen - En diskursanalys av europeiska staters inställningar till utsläppsreduktioner
The European Union is a self proclaimed leader in the field of climate change and has a common target for reductions of greenhouse gas emissions. In spite of this, there are great differences between the member states capacity and dedication to the cause of implementing the Unions climate policy and reduce their emissions. The purpose of this thesis is to contribute to an understanding of how different European states construct their identity in the context of climate change mitigation. By analyzing national documents from three European states and using tools deriving from discourse analysis, I aim to illuminate differences and similarities in their rhetoric. The result is that due to the states relationship to the European Union and the United Nations, there are great similarities in the way they construct mitigation and their identity.
Att se sig själv som en del i ett större perspektiv : En analys av skolämnet historia i Lgr 69, Lgr 80 och Lpo 94.
In this essay, I intent to examine history as a school subject in Swedish compulsory school (for children aged 7-16), it contains mostly an analysis of the syllabus for history in the three latest curriculums Lgr 69, Lgr 80 and Lpo 94. The main purpose of the essay is to illuminate the development and the change history as a subject has gone through during this specific time, and my will is also to illustrate the view on knowledge and learning that is revealed in the syllabus for history in today?s curriculum (Lpo 94).The survey shows that in Swedish compulsory school, history as a subject has changed significantly. During the examined years, the contents have been exceptionally broadened and that has lead to increasing demands on the students as it has gone from being directed to the individual and its contiguous history with shorter outlooks on the rest of the world, to requiring the individual to be able to see and understand other parts of the world and different time, on the basis of it?s own history and culture.
Utomhuspedagogik i förskola
Föreställ dig hur en modern stad - vad skulle hända om man placerar en enorm glaskapsel över den? Hur lång tid skulle det ta innan livet däri skulle upphöra? Förmodlingen ganska snabbt. Med detta enkla tankeexperiment förstår vi hur beroende vi är av naturen - även i staden. Vivarium är ett latinskt ord som betyder ?plats för liv?.

Ha?llbarhetsredovisning i bostadsfo?retag : En rekommendation
This project was conducted on behalf of the organization SABO (Swedish Association of Public Housing Companies). The aim of this project was to investigate which relevant environmental aspects and indicators there are for housing companies to present in their sustainability report. The project consists of three main goals: to decide if there is a need for common guidelines when conducting a sustainability report, determine appropriate environmental indicators and to create a simple model of how the companies can present them. This was done by a literature study, analysis of 13 sustainability reports and interviews with seven housing companies. The result of the project suggests that there is a need for common guidelines to, among other things, make it easier to make a comparison with other companies.
Miljöpåverkan vid marksanering - emissioner vid sanering av fastigheten Trädgården 1:124 (Hexionområdet)
Naturvårdsverket har enligt en genomförd kartläggning funnit drygt 80 000 potentielltförorenade områden i Sverige. På de potentiellt förorenade områdena har exempelvis olikatyper av industriell produktion ägt rum som kan medföra att området har förorenats. I MölndalsKråka, 500 meter öster om Mölndals centrum i Göteborg ligger en stor industrifastighet därindustriell produktion i form av tillverkning av olika kemiska produkter t.ex. i form avbindemedel till färgindustrin, har pågått sedan 1800-talet. Marken inom det s.k.
Restriktioner av växthusgasemissioner : hur påverkas lantbruksföretagens ekonomi och produktionsinriktning?
The agricultural sector accounts for about 13 percent of the total load of greenhouse gas emissions from Sweden (Swedish Environmental Protection Agency, 2007). The Swedish objective to reduce the greenhouse gas emissions with 40 percentage units to the year of 2020, based upon the year of 1990, might imply stricter regulations for Swedish farmers. A regulation or other forms of economic incentives is probably necessary to reduce the emissions originating from the agricultural sector.
This study aims to investigate the economic and managerial impact on two agricultural firms with differing production system given that a constraint on green house gas emissions is introduced. Gases included in this study are carbon dioxide, methane and nitrous oxide.
pH-sensitivity in boreal streams ? the influence of landscape characteristics
The goal of the society to increase the proportion of renewable energy has led to an increased demand of bioenergy e.g. forest biomass. However, there are concerns that removal of biomass will lead to decreased base cation concentrations in the soils and acidification of streams. In order to find in which types of landscape removal of branches and tops could have such negative effects, this study aims to analyse the relations between pH-sensitivity and landscape variables in the Bothnia Bay water district. GIS and digital geographical data were used to analyse the landscape in subcatchments.

How will China?s entry on the market of forest products affect the global forest market?
The purposes of this study are to describe production, consumption and trade of forest products, and China?s possible competitive advantage in the forest industry. The purpose of this study is also to describe how China?s entry on the forest market affects the world market of forest products.
Försök med Rhodamin i vattensystemen på SSAB Tunnplåt AB i
Luleå
SSAB tunnplåt AB i Luleå vill kunna styra processerna i masugnen, vid stålverket och koksverket på ett sådant sätt att i första hand gränsvärden och i andra hand riktvärden inte ska kunna överskridas mot recipienten Inre Hertsöfjärden. För att kontrollera att dessa värden inte överskrids sker varje vecka egenkontroller av SSAB:s vattensystem. Vid driftstörningar sker dessa egenkontroller dagligen om det är nödvändigt. Som ett led i denna egenkontroll har SSAB behov av att skaffa sig bättre uppfattning om uppehållstider och utspädningsfunktioner i de befintliga systemen som finns tillgängliga för transport av kyl- och processvattnet. Syftet med detta examensarbete har därför varit att ta fram ett underlag, angående uppehållstider och utspädningseffekter i vattensystemen på metallurgiområdet och på koksverket, som SSAB kan använda sig av vid driftproblem eller driftstopp.

Låsanordning med induktiv laddning för elcyklar
This thesis has been adjusted because some parts are classified, some sentences might have been changed. Electric bikes are a convenient mode of transport, a good choice when long distances or tough slopes can be an obstacle.The goal of the project was to create a prototype on a locking mechanism with an inductive charger for electric bikes.The idea behind the project was to develop a user-friendly locking mechanism, where the bikes would be charged inductively when they were locked. To implement the project facts about induction, battery charging and locking devices was needed to be acquired. Circuits for induction charging were created and a lock device was constructed. A microprocessor was used to control the entire system.A prototype was designed with a locking device and an inductive charger fixed in a bike rack.The entire project became very wide which resulted in that not all of the parts of the project could be completed.
