The work covered in this report includes a literature study of the diesel dual fuel technology(hereinafter referred to as DDF). The literature study covers earlier work that has been doneregarding the use of compressed natural gas (CNG) and diesel in a DDF system. Moreover a onecylinder research diesel engine was fitted with a CNG fuel system for experimental testing. Theinstallation of the engine and the test cell is described. Results from the tests are presentedcovering emissions, heat release and pressure traces from the DDF-concept.During the literature study it was found that most research was related to heavy duty dieselengines.

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

The purpose of our research was to explore the social situation of unaccompanied children. We also aimed to reveal the relation between their social situation and their identity development. The overall purpose were to describe their social situation, the value of significant others, how different languages influence their identity development and finally how their origin affects their future dreams.In order to achieve the best result in our research a qualitative method was used. This was based on qualitative interviews and was disposed around a very loose set of questions in order to let the interviewees lead the way. The analysis of the result was conducted on the basis of a set of theories and concepts in order to understand the identity development.

Purpose: The purpose with the essay is to examine how some teacher?s works with intercultural questions, if they are looking after student?s cultural background, earlier experiences and knowledge?s in their teaching. We have formulated three questions whom we want answer to.Method: The essay began with a theoretical research to get more knowledge of intercultural pedagogic. The study part is based on seven interviews in two schools in Södertälje, five with teachers and two with assistant principals. The conclusions of our essay are based on the results of our study.Result: The study shows that the two discourses ?national self-understanding? and ?the democratic credot? still lives and compete with each other.

The purpose of this Master?s thesis is to investigate how public library users consider the knowledge of the librarians and to examine what the users expect from the librarians. To begin with, we contemplate our own view of the librarians, their knowledge and what help we expect at the library. Realising that we do not expect particularly much from librarians, although we have studied to become librarians for two years, we assume that the regular library user does not expect much either. This assumption resulted in our decision to investigate this particular question.

This thesis constitutes a long term (100 year) ecological landscape management plan for the estate Götebo 1:5. The estate is situated close to Gothenburg and is owned by Skogssällskapet. The planning has been made by dividing the estate into different areas (zones). In each zone one of the goals nature conservation, recreation or economical yield has been prioritized. Nature conservation is one of the main goals for the forest management plan.

AbstractThe purpose of my study is to find out how students who are going to special school feel about going to that type of school compared to going to the regular school. I also want to know what they know about integration and a school for all, if they even know about the research that has been done and still is being done. I chose to interview two students to find out what they think about the subject. The two students go to different programs of special school in high school. I chose the method of interviewing because I wanted to get a vivid conversation and to be able to do follow-up questions.

Detta arbete undersöker hur homosexuella killar skildras i ungdomslitteraturen. Syftet problematiserar dikotomin maskulint/feminint och män/kvinnor. Målet är att införa ett icke heteronormativt perspektiv i ungdomslitteraturforskningen kring genus och queer. Detta görs utifrån teorier av Judith Butler, Tiina Rosenberg och R. W.

Bakgrunden till vår studie är vårt gemensamma intresse för skönlitteratur och vår nyfikenhet över hur den används i dagens skola. Syfte var att ta reda på om samt hur lärare, verksamma inom skolans tidiga år, använder sig av skönlitteratur i sin undervisning. Vi har undersökt hur lärare tänker kring skönlitteratur i sin undervisning och i vilka syften som skönlitteratur används. Genom kvalitativa intervjuer med sex verksamma lärare fick vi det material som vi sedan analyserade. Vi fann att lärarna var väl medvetna om skönlitteraturens möjligheter, inte bara i svenska utan i skolans alla ämnen.

This thesis presents a system which has been implemented to satisfy a need in theresearch on how speech planning interacts with syntactic and prosodic structure inspontaneous speech. The long-term purpose of the research is to provide models forautomatic parsing of spontaneous speech and for psycholinguistical modelling of speechproduction. Identification of inhalation pauses is an important step in the developmentof automatic methods for spontaneous speech parsing.Identification of inhalation pauses is considered to be a keyword-spotting speechrecognition problem. Hybrid HMM(Hidden Markov Models)/ANN(Artificial NeuralNetworks) approach is applied to this problem. Method gets 90,8% in Recall, 66,4% inPrecision and 76,7% in F-score.

This thesis has been carried out to the Technology Group at industrial plant Tube Mill2012, which belongs to the Sandvik AB. Technology Group is a unit that takes care ofall requirements and suggestions regarding investigations, test runs and designmodifications. The main objective is to identify and analyze the existing initializationprocess to see where improvement opportunities exist and to come up withsuggestions for improvement, supported by previous research and literature. Anextensive literature search and case study has been conducted to provide a solidfoundation to refer to during the work. Completing the interviews and the workshopgave a clear picture of their unstructured work and approach, how the lowrequirements on the received orders caused problems for the group as well as thelack of a standardized resource allocation method provides major delay factors.Solution proposal then became a very easy process model in five steps with all theinformation gathered in one place.

Forskare, föräldrar och förskolepersonal har sedan länge lagt märke till att inlärningen av färger och deras beteckningar skiljer sig från inlärningen av andra adjektiv och från substantiv. En undersökning har genomförts med syftet att komma närmare svaret på frågan: hur går det till när barn lär sig kopplingen mellan färg och färgterm? Ett trettiotal barn i åldern två till fyra år har deltagit i ett test med tre delmoment. Analysen har utgått från tre frågeställningar: Hur ter sig kopplingen mellan färg och färgterm i olika åldrar? Finns det någon skillnad mellan enspråkiga och tvåspråkiga barn? Följer barns inlärningsmönster den av Berlin och Kay (1969) föreslagna implikationsordningen? Undersökningsresultaten visar att redan barn som är två år kan göra en korrekt koppling mellan färg och färgterm.

The purpose of this Masters thesis is to make an outline of different methods and theories within the field of bibliometrics and critically review their strengths and weaknesses. The author studied literature that discussed bibliometric methods and theories. The number of empirical studies that are based on bibliometric methods and theories are numerous and where principally excluded, but some empirical studies were included as part of the argumentation for and against different methods and theories. The author first gives an outline of which methods and theories there are and describes their different strengths and weaknesses. Citation analysis has many different fields of application such as information retrieval, mapping science, evaluative studies and monitoring literature.

The purpose of this essay is to examine the impact on children playing at a preschool yard that is designed with traditional playground equipment, and a nature-like yard without traditional playground equipment. How these respective environments influence children?s play, which other factors in the external environment that affect the game and whether the theories in the literature correspond with the results were important questions for the essay. To answer these questions a case study was applied onto two specific preschool centers, both located in Malmö. Through literature studies, inventories, observations and interviews with staff and children, a picture become clear of how the children use the yard and how their play is affected by the design of it.

This paper relates a debate on a book Vetenskapen och förnuftet (1986) written by the Scandinavian philosopher Georg Henrik von Wright (1916 - 2003). The book brings up fate of mankind, raising the question if human rational thinking and scientific achievements are threatening our very existence on earth. Shortly after the book was published, it was intensively debated in a leading Swedish newspaper Svenska Dagbladet. Some 20 leading politicians and scientists contributed with their criticism during spring 1987. The paper highlights this debate by writing reception history, describing how the book with its serious message was received by leading scientists of the time.
