The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

Studien är en applicering av Foucaults Övervakning och straff på science fiction-romanen The Left Hand of Darkness av Le Guin. Fokus låg på hur makten drabbar huvudkaraktärerna; syftet var att notera hur de gör motstånd mot maktutövningen och att ta fasta på alternativa maktrelationer som kan influera verkligt politiskt arbete mot en bättre, mer jämlik värld. Att använda Foucaults idéer på liknande sätt är vanligt. Analysen består av sex sekvenser som utspelar sig på planeten Vinter i The Left Hand of Darkness. Landsförvisningar för att återupprätta härskarens makt, både avsaknaden och upprättandet av framstegsmyt och en etik som förespråkar jämlikhet utmärkte monarkin Karhide; kuvade kroppar i disciplinens förtecken och en makt som är sammantvinnad med vetandet kännetecknade byråkratin Orgoreyn.

The purpose of this study has been to look into and analyze the view on sex equality in textbooks and teaching media, and teaching of a group of upper secondary school teachers, through a gender perspective. The teachers teach subjects within social- and political science. The two questions that I wanted to answer are: What views do the teachers have on sex equality in their teaching? What views do the teachers have on sex equality in the teaching media (textbooks and other teacher media) which they have access to? Since I wanted to look into the teachers own views I chose unstructured interviews as the method of gather empirical information. To interpret the transcribed texts I chose the hermeneutic view of people as intentional.

This paper is an attempt to distinguish the specifics of the conflict resolution process and the negotiations during trade conflicts. First of all, this kind of conflict almost always contains some kind of protectionism which doesn?t make sense economically. Imposing trade-barriers decrease the overall welfare of your own nation and the only winner is the protected sector. These policies can be introduced since the political pressure from threatened industries is usually much stronger than the pressure from the consumers who will bear the burden of protectionism.

This essay examines the Alberte triology, by the Norwegian writer Cora Sandel, from a gender/feminist perspective. Taking Yvonne Hirdman's theory about the gender system as a starting point I will show how the living conditions and the different roles of men and women are represented in the novel and how they are changing during the centuries before and after the First World War.I am particularly interested in Alberte, the main character, what attitude she takes to her position in the gender system and in what way she differs from the traditional female model. Is she a New Woman, a different ?species?, who doesn't fit into the rigid gender system? Does the New Woman have a male counterpart, and is he to be found in the novel? Does the novel give a positive vision of a future where men and women can meet as equals?.

This report is introduced with a presentation of fundamental electromagnetic theories, which have helped a lot in the achievement of methods for calculation and design of microstrip transmission lines and circulators. The used software for the work is also based on these theories. General considerations when designing microstrip solutions, such as different types of transmission lines and circulators, are then presented. Especially the design steps for microstrip lines, which have been used in this project, are described. Discontinuities, like bends of microstrip lines, are treated and simulated.

Forskningsrön tyder på att organisatoriska och sociala faktorer är den största anledningen till att 90 % av implementeringarna av ERP-system misslyckas. Förespråkarna för involvering av användarna för lyckad implementering är många. I denna studie har vi belyst en fallstudie i en relativt liten livsmedelsorganisation där det har studerats vikten av kommunikation och kommunikationsrutiner för att ta till sig ett nytt system samt hur detta har påverkat organisationens anställdas acceptans gentemot det ERP-system de implementerat. Denna studie visar att om kommunikation innefattar kunskapsförvaltning och kunskapsspridning kring det ERP-system som implementeras kan det innebära större acceptans hos användarna, då de får förståelse för varför saker och ting sker samt varför deras arbetsuppgifter ser ut som de gör, en kontext kring sina aktiviteter. Vi fann att kommunikationssättet, det vill säga huruvida den var formell och rutinartad eller informell, inte påverkar utfallet av användarnas acceptans gentemot ERP-systemet, så länge kontexten för aktiviteten förmedlas.

Due to the fact that bottled water has negative impact on the environment,Elite Hotel hasdecided to stop serving bottled water in their restaurants. Since Swedish tap water is regarded tohave great quality,Elite Hotel wants to look at the possibilities to carbonate their own sparklingwater and serving it in fancy carafes. This Master of Science thesis is about constructing a costefficient water carbonator system that suits Elite Hotel?s need specification. This thesis alsocovers other water refinement criteria.The work has been divided into three parts.

In this study, the aim is to show how the social services fails to implement a specific rights law (LSS) wich is supposed to have the function of protecting the wellfare and provide specific rights to people with severe mental disabilities. By applying chritical theory on this case the aim is to provide an alternative answer on why it is possible for the social services to ignore these peoples rights.By revealing the power structures in the encounter between the system and a person with mental dissablilities, I conclude that people with mental disabilities does not fit in when it comes the social sevices way of implementing the law and further more that a private person is extreamly exposed to the systems arbitrariness..

Organisationsförändring behövs för att bevara hög effektivitet i organisationer när omvärldenförändras. För större organisationer behövs en tydlig avgränsning arbetas fram innanorganisationsförändringsarbetet startar. Landstinget i Värmland behöver utföraorganisationsförändringar på grund av ett föråldrat IT-system som används i verksamheten. Enmålgruppsanalys har genomförts av IT-systemet vilket resulterade i tre målgrupper. Intervjuer medpersoner ur de tre målgrupperna har genomförts vilket resulterade i data som användes till attanalysera och svara på rapportens två forskningsfrågor.

The aim of this masters thesis is to examine query expansion. Query expansion is the process of adding new terms to a query to improve the retrieval effectiveness. In this study the baseline query was expanded in five different modes. The first expansion strategy was formulated by the inflected terms as the system does not allow truncation, I have inflected the terms, e. g.

The purpose of this thesis was to ease the implement of an upcoming intranet for a target group who had used the previous system to an unwanted low extent. After qualitative and quantitative studies I found that the users of the current intranet thought it was hard to navigate and did not understand neither the relevance of it in their own work nor knew which information it contained.Since I did not have access to the new system by the time of the making of this thesis I concentrated on rectifying possible problems with the new system regarding the relevance and the contained information. With basis in a number of theories I produced an information brochure, whose object was to inform about the content and to convince the target group of the relevance and utility of the new intranet. .

The purpose of this study is to examine to what extent the senior level Swedish school can be viewed as supporting, or counteracting, a colonial discourse that legitimizes global and national injustices. The study is executed through a discourse analysis of five textbooks in social science for senior level Swedish schools.Using elements from Foucault and Edward Said a theoretical framework is constructed, in which a colonial discourse is perceived as structured around four clusters of ideas, namely (i) the use of dichotomies, (ii) the concept of progress and civilization, (iii) the construction of -we- as synonymous with (ii), and (iv) the construction of -the others- as the opposite of (ii) and, therefore, the opposite of -us-.The results show that a colonial discourse is still highly present in the textbooks, in that the texts are structured around dichotomies such as tradition/modernity and democracy/dictatorship. Sweden and the Western world are perceived as closely associated with democracy, freedom, and modernity, whereas -the others- of the world are being associated with e.g. poverty, conflict, tradition, and ignorance. -The others- within Sweden, i.e.

Många lärosäten använder idag fler än en lärplattform, ibland inom en och samma institution, program eller kurs. Uppsatsens syfte var därför att ta fram riktlinjer för vad som bör beaktas vid val av lärplattform för att fylla organisationens behov och passa dess förutsättningar. Undersökningen genomfördes med en kvalitativ datainsamlingsmetod där vi genom intervjuer med fem lärare vid Linnéuniversitetet samlade in deras krav. Resultatet blev en checklista som listar lärarnas krav och genom att kritiskt granskat litteratur kan vi rekommendera organisationer vad de bör överväga inför implementationen av en lärplattform..
