The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.

This thesis is a case-study of an ongoing court case between the Swedish Competition Agency and Växjö Municipality about a set-up requirement to the long-distance heating system for newly built private houses on municipality owned land. This requirement was set up as part of the municipality?s long-term environmental goals; however the Competition Agency claims that the demand is damaging the free market in the municipality. The purpose of this thesis is to determine which normative assumptions the decision makers have based their actions and re-action on, and whether or not these assumptions are valid, thru theoretical ideal types. This is determined via method of textual analysis.

Vellinge is one of few municipalities in Sweden that refuses to accept refugees. The subject of this thesis is to find out how the local politicians in Vellinge make their considerations when they decide not to welcome refugees. The analysis uses the representation theory as a starting point. The two ideals of the representative role, either as a bound mandate or as a free independent role, is the base of the analysis. Vellinge is in the analysis compared to Lomma, a very similar municipality in southern Sweden that for a long time alsohas refused to accept refugees, however suddenly in 2007 decided to change their mind.

The purpose of this thesis is to reach a deeper understanding of the context of teachers? information seeking. Research in the role of the library in a learning perspective is in demand. To reach our aim we investigate what teachers say about their experiences of the user training during their studies and what effect it had on their information seeking as teachers. We interviewed four teachers and analyzed the transcripts of their sayings about their experiences of their information seeking during their education and a teaching profession.

The purpose of this paper is to examine how teachers choose to work with the teaching of reading and writing skills, how teachers justify their choice of teaching method and how the documentation of student development is being used. This paper also discusses the definition of reading and writing, phonological awareness and how different reading- and writing educational methods can be combined. The gathering of information has been done through a literature review in which I have looked at past research on reading and writing. I have also conducted qualitative interviews with teachers involved in literacy learning. The result of my research shows that it is not possible to determine which literacy learning methods that are most effective.

The purpose of this study was to increase the knowledge and understanding of what impact support-groups, such as represented by Qvinnoqulan, can have on women with drug-addiction. The questions at issue for the essay was: How does a selection of women who participate in Qvinnoqulan describe their thoughts, experiences and reflections of the group? What sense has Qvinnoqulan made for the women on a personal level and for contributing to live a life without drugs? To answer the questions a qualitative method was used and five interviews were made with women who participated in the activities of Qvinnoqulan. To analyze the data a social constructionist perspective and an empowerment perspective was used. The result of the study showed that the women were in the process of rebuilding a new life without drugs and reconstructing a new identity.

Outdoor advertising is not very often discussed within city planning even though the commercial messages occupy much of public space. The advertising signs affects not only the physical environment but also social life. In this report I would like to acknowledge and question the presence of advertising in our everyday environment. Outdoor advertising is not a new phenomena, technical progress however, results constantly in new expansions in the environment. Today advertising occurs in all sorts of shapes in the cities, both as free standing signs and as signs attached to facades, incorporated in city furniture such as bus shelters and on vehicles moving along the city streets. Grouping advertising into two categories; local and national, reveals that the different categories have different impact on public space.

Har NAFTA-avtalet (North American Free Trade Agreement) som 1994 ingicks mellan Mexiko, USA och Kanada, haft de effekter på den mexikanska jordbrukssektorn, speciellt dess majssektor, som kan förväntas i enlighet med nationalekonomisk teori? Detta är den huvudsakliga forskningsfrågan som denna uppsats försöker undersöka och besvara. Min slutsats är att i fråga om Mexiko är svaret i huvudsak beroende på vilka producenter man väljer att studera. När gäller dess majssektor är effekterna av NAFTA på de konstbevattnade producenterna, företrädesvis i norra Mexiko, mer eller mindre i linje med vad som kan förväntas, medan effekterna på de regnbevattnade producenterna företrädesvis i södra Mexiko ej följer det förväntade mönstret. I en fortsatt analys av NAFTA-avtalets konsekvenser, framstår behovet av statliga interventioner mycket tydligt.

This master thesis is looking into the stories on the internet forum www.resedagboken.se. The stories of Swedish teenaged exchange students in the U.S. are studied and the main purpose is to see both what they are writing about and the reason for why they are spending their time writing down their experiences in a public forum.Even though most of the teenagers here are writing with a specific audience in mind, all the stories are free to anyone to take part of and this causes a difficult position for the teenagers who often seem to forget the public point of view when they are telling about their personal lives.The study is divided into two parts. The first one looks into the content of the stories and the other one focuses on the storytellers and their reasons for writing. The teenagers are writing both a lot about their everyday lives in their new environment, but also a lot of things to keep in touch with what their friends and family in Sweden are doing.

The purpose of this essay was a follow-up of four female drug abusers with several mental problems ten years after my initial meeting with them at Korsaröds Behandlingshem. Using a qualitative method and interviews with the women, knowledge was obtained regarding their current vital conditions and their subjective experiences of the treatment at Korsaröd. Their perspective on the ethical as well as their desired relationship with staff within social services was also accounted for. When contacted the women lived a content and drug free life in their own flats. The women stayed at Korsaröd approximately five years, and they said that without the treatment they would not be alive today.

 Syftet med studien var att genom intervjuer och observationer undersöka pedagogers delaktighet i den fria leken i förskola och förskoleklass. De frågeställningar som låg till grund var, Vad innebär vuxnas delaktighet i barnens fria lek? På vilket sätt kommer den vuxnes delaktighet till uttryck i den fria leken? Detta för att vi ville veta om vuxna deltar och på vilket sätt de deltar i barnens lek. Vår studie är kvalitativ och i metoden är vi inspirerade av fenomenografi och sociokulturellt perspektiv. Studien grundar sig på sju intervjuer med pedagoger i förskola och förskoleklass och på observationer, en i förskola och en i förskoleklass.I resultatet kom vi fram till att vuxnas uttryck av delaktighet har visat sig på flera olika sätt.

Stick- och skärskador är ett problem inom sjukvården. Förekomsten är störst inom operationsverksamhet, där stora mängder blod och andra kroppsvätskor samt vassa instrument hanteras. Risken för blodsmitta varierar för de vanligaste blodsmittorna HBV, HCV och HIV men när tillbud sker finns alltid en möjlig risk för blodsmitta.Syftet är att identifiera orsaker till stick- och skärskador samt beskriva åtgärder för att minska risken för blodsmitta under den intraoperativa fasen.I ett operationsteam ingår många olika yrkesgrupper som arbetar nära varandra på en begränsad yta och risken för tillbud ökar Risken för operationsteamet kommer aldrig helt att kunna elimineras, men genom att identifiera orsaksfaktorer, såsom handskperforation, operationslängd och blodstänk finns möjlighet att påverka sin egen och övriga i operationsteamets säkerhet. Genom att använda olika skyddsåtgärder som dubbla/indikatorhandskar, mun och ansiktsskydd samt användandet av preventiva arbetsmetoder som Hands-free teknik (HFT) och trubbiga nålar kan eventuella risker för blodexponering och en potentiell risk för blodsmitta minska..

The industrial sector accounts for a large share of greenhouse gas emissions. To reduce its negative impact on the environment is crucial in the quest for a sustainable future. In discussions of the industrial sector's impact on the environment guidelines have been highlighted as a tool to assist the industries in their efforts to change the relationship between the consumption of energy and production. This by improving energy efficiency and a shift to the best available technology. During the past 30 years the steel industry has reduced its energy consumption per ton of steel produced by 50 percent.
