The purpose of this work was to provide a better understanding of urea?s decomposition and byproduct formation in an SCR system on heavy trucks. In my experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition products. Chemicals such as urea, biuret, cyanuric acid and melamine of p.a. quality were used in this method development. Beforehand, there was no FTIR method available to detect these substances; hence, the aim of this work was to develop an FTIR method to understand the degradation chain of urea. The combination of TGA and DSC was used for analysis of different samples, where urea, biuret, cyanuric acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e.

I have in my thesis, examined the possibilities in terms of energy for a condominium association.To have an effective and good energy is becoming increasingly important with today's rising electric and oil prices. In my thesis I have used the condominium association Kärralyckan, which is situated in Falkenberg. The buildings at Kärralyckan are built in the mid-1970s, and are heated by electric radiators. The tap water is heated by an electric boiler.Based on that calculation I can show the various energyststem. The different solutions have been developed by contact manufacturers and installers through phone calls and e-mail.According to the results shows that geothermal heating has been a great solution for Kärralyckan.

This thesis examines the way that subversivity is produced in relation to the name of the author, as understood by Foucault, and what potential for ressistance that can be glimpsed there. This from the reading of three text that in different ways relate to that theme.Firstly, throught the reading of "Isis mamma a?r genusvetare, skribent och konstna?r, min mamma a?r f.d. sta?derska, kokerska och dagisfro?ken, numera fo?rtidspensiona?r med diagnosen fibromyalgi" by Lidija Praizovic?, a text that actively work with the internal production of different exteriorities.

Barley is one of the most important cereals cultivated in the Nordic countries. Climate change brings warmer and moisture climate which favors fungal diseases. In the cropland barley can be seriously infested with hard fungus attack. Since it is important that the yield bears a high quality it is of great importance to find varieties more resistant to attacks.Pathogenesis-related (PR) proteins are stress proteins induced in the plant in response to infection and abiotic stress (van Loon, 1997). PRs are shown to have antimicrobial activity differing between bacteria, fungi and oomycetes (Tandrup Poulsen, 2001).

This thesis deals with two types of agrarian remains in relation to settlement remains; clearance cairns, low stone walls and house terraces in the area of Northeastern Uppland and the area north of Lake Mälaren, during the middle Iron Age. The aim whit this thesis is trying to get a better understanding of the relation between agrarian and settlement remains in Uppland. Three places have been chosen where these three elements are present and they are interpreted through Richard Whites concept of middle ground but also Landesque capital. The three elements have shown to be expressed in different ways in all three sites. It is possible to see two areas with different traditions, but also to see two areas that closely interact with each other, this opens up for a new discussion around agrarian remains in both areas.

AbstraktHaving influence over questions that concern us is a part of the society that we live in, where every individual have the right to make her voice heard (Danell, 2006). For many decades, the school has had many different ways to give the students influence. Rönnlund (2013) is giving a historical overview of the history of students influence and enlighten us how the influence has changed over time. The influence from the students is very important and it is the students right to make their voices heard about things that concerns their work environment but also to affect their curriculum. The education in school should be fitted to every individual student (Danell, 2006).   According to Aaron Antonovsky (2007) our wellbeing is based on that we all can take part and deicide about the things we are meant to do.

In musikklasser (a special musical training which focus on choral singing is offered in the Swedish compulsory school from the age of ten until the age of sixteen) teachers are working in a tradition where conventions relating to singing with children have developed in accordance with the Swedish choral tradition. In these classes, students are trained in large groups, usually around 30 students in one class. Furthermore, one teacher and 60 students is also frequent in schools with two or more parallell grades. In a large choir group, students develop their skill in choral singing, which includes the development of general musical knowledge as well as the development of the individual singing voice of each student in order for the choir to be able to interpret and perform music with a communal musical expression. Thus, the complexity in this teaching and learning setting places high demands on the choir teachers? ability to use appropriate teaching and learning strategies in order to develop the specific musical skill required in a choir.In this study, two choral teachers´ interaction with their choir class were investigated.

In this essay I have chosen to take a closer look at gold figure foils (Swedish ?guldgubbar?), find their context and analyze it. I have analyzed some earlier studies about gold figure foils that were found in Scandinavia.The focus of my study is based on the locations of the findings. Another important aspect is to discuss if the encountered gold figure foils that were folded and cut looked like that due to intentional motives or not.My conclusion is that when it comes to the locations of the findings they are mostly found in houses irrespective of if it´s in a posthole, wall or house foundation.The other conclusion is that the gold figure foils could have intentionally been manipulated before they ended up in the ground..

Världshandeln växer kraftigt och det vanligaste sättet atttransportera gods mellan landsgränser är genom sjöfart. I takt med attvärldshandeln växer, ökar också storleken på fartygen. Detta innebär att enstörre mängd gods anländer samtidigt när ett fartyg förtöjer vid en hamn. Föratt hantera denna ökade mängd gods måste godsnav och hamnar ständigt utvecklaoch effektivisera verksamheten. Detta innebär att långsiktiga prognoser ochplaner måste utvecklas för hur större fartyg skall kunna hanteras.

Invandrade kvinnor i Handels. Föreställningar om arbetskraftsinvandrade kvinnor i Handelsnytt 1961-1976. (Immigrant women in Handels. Conceptions of labour immigrated women in Handelsnytt 1961-1976).The primary purpose of this thesis is to analyze the written conceptions of labour immigrated women in Handelsnytt, a Swedish Trade Union magazine. The analyses of the conceptions are based on theoretical categories of class, gender and ethnicity.

SourceURL:file:///Users/sofiahultin/Desktop/AMDex/Summary%20of%20essay.docI my essay I describe my master project Alla måste duscha ? en gympasalsredovisning/ Everyone has to shower ? a school gym presentation. Through my work I investigate possibilities for action and agency in a limiting space; the gymnasium. With the help of Mika Hannulas book Politics, Identity and Public Space: Critical Reflections in and through the Practices of Contemporary Art, I discuss how the stories I tell trough my project can be seen as suggestions for a possible reality. By adding my stories to the old ones (that create our society) I hope they, if only just the slightest, can influence on how we look at reality and on a possible reality.

In this essay, I make a queer feminist analysis of Mats Strandberg?s and Sara Bergmark Elfgren?s teenage novel ?Cirkeln?, which is about six teenage girls who learn that they are witches with a mission to save the world from demons. Using Judith Butler's theories, I examine the norms of sex/gender, ethnicity, class and sexuality found in the text and how these standards are created. I also analyze whether, and if so how, these standards may change when the magical elements enter the text.I also discuss the fact that older Gothic novels with magical elements often have been regarded as queer through history. .

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.
