The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.

The purpose of this master thesis is to investigate how librarians working in academic libraries are experiencing the reference situation from a pedagogical point of view, by applying a theoretical framework consisting of learning strategies and their different characteristics, to qualitative interviews. Other goals are to elucidate the fact that learning takes place every day at libraries during the reference situation and that this work must be seen as ?one of the most important activities that takes place at the library?, using the words from one of the interviewed librarians, but also to make place for more discussions regarding pedagogic and library work. This is done by posing questions about knowledge, learning, information literacy, communication, the reference encounter, the roles of the librarian, policy and also architectural aspects of the reference situation. The interviews were taped, transcribed and categorized according to the earlier mentioned areas of interest.

The aim of this study is to have a deeper understanding about the motivations and the obstacles of an immigrant?s language learning. I have studied the problem with focus on integration and language learning. The study is principally based on deep interviews with Turkish immigrants. I have studied the question by means of a socio-cultural perspective of learning; Mead?s conceptions I, Me and the generalised other; Scheff?s conception, the social bonds and Freire?s conception, dialog and Asplund?s conception social responsiveness.

The aim of this study was to investigate what formative assessment means and get information about how teachers? assessment practice in formative assessment can look like, based on five key strategies. I have observed five teachers in grade 4 to 6 during a week of their mathematics teaching. Formative assessment is assessment for learning and has the purpose to support students? knowledge development.

From autumn 2008 Sweden has reinstalled the Special Education Needs teacher education. For future special education teachers and active teachers in the field, it is important to know the history and be aware of future visions to create a good role for the Special Education Needs teachers. This study examines attitudes towards special education and Special Education Needs teachers amongst school principals and classroom teachers at seven schools in Umeå municipality. School principals were interviewed, and a survey was handed out amongst the selected General Education teachers. From this it appears that school principals have a picture of special needs education and Special Education Needs teachers' work that corresponds well with the objectives of the school's governing documents.

In my study I have chosen to examine the mathematics in children's free play and everyday situations, with focus on sorting and classification. The purpose of the study was to see how children express their mathematical knowledge. I have chosen to use a qualitative method in my examination, here I did observations in a children's group where the children were between three and six years old. I also did interviews with the teacher's on the department to see how they relate to the mathematics and how they formulate the department to achieve as good a learning environment as possible.The result shows that the teacher's approach is incredible important to the children's learning ability and that they are always present to challenge and discuss together with the children. The observation indicates that children use mathematics all the time in their everyday situations and that it is the interaction between individuals and environment that affects children's development. .

The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.

Lärplattformar används idag i allt större utsträckning vid distansundervisning. Forskning pekar på att lärstilar är en viktig faktor att ta hänsyn till vid distansundervisning, dock är området beträffande lärstilar i relation till lärplattformar relativt outforskat, och det saknas tydlig vetskap om hur lärplattformar kan designas för att stödja olika lärstilar. Den här studien undersöker lärstilar i relation till funktioner i lärplattformar, genom en explorativ ansats och studie med designinslag. Utifrån en litteraturstudie identifierades funktioner i en lärplattform, vilka ställdes i relation till Kolbs teori om lärstilar för att mynna ut i ett antal rekommendationer för undervisning och användning av funktioner, som låg till grund för utformning av en prototyp. Prototypen fungerade som underlag för den empiriska undersökningen, vilken genom intervjuer utgjorde prövning av rekommendationernas relevans, samt kartläggning av hur funktioner i lärplattformar stödjer olika lärstilar vid användning.

AbstractThis research is about pre-school children?s conceptions of the river and the water environment. The aim of this study was to apply a new teaching method based on the outside learning, as well as to test the method and see if it works, i.e. if children get more knowledge this way compared to ordinary methods like teaching in the class-room which involves showing pictures and discussion of them.The main questions in this study were how children get new knowledge through outside learning and how effective this learning method is, i.e. how much they noticed and learned about the river and the water environment as a result of that outside observation.

The goal and purpose of this essay is to study if and how multimodality is used within a Swedish school in Kalmar. This is accomplished by observing the different modalities inside the classroom and how the use of different modalities affects the teaching. Unstructured observations combined with a material-based thematic presentation leads up to an analysis based on social semiotics and multimodality. The essay shows how the teaching uses lots of modalities: sound, images, movies, speeches and literary text in lots of different ways. These different types of modalities are used in a multimodal context, providing good conditions for learning..

Background: There are many possible reasons why a patient gets a stoma and in every case it?s of importance for the nurse to adjust nursing care, information and patient education from individual presuppositions. Problem: Patient education regarding stoma self-care is an important part of the nurse?s work within stoma care. The patient is depending on the guidance of the nurse and therefore it is relevant to illuminate the importance of education regarding gaining ability to perform self-care.

In today?s society there is a discussion regarding students? level of knowledge and personalisation. The classrooms consist of heterogenic groups of students with different learning needs and levels of knowledge. The purpose of the present study is to find out how the students who participated perceive the teaching of English as an additional language with regards to personalisation, and how they believe differentiation can help develop and deepen their learning. This study has been conducted using a qualitative method with interviews as the core, complemented by observations. The results have been analysed and interpreted hermeneutically. The results show that those students who have a positive attitude to English education, irrespective of their grade, are those who see the benefit of knowing English outside the classroom, and thereby create a connection between reality and studying English.

Bakgrund: Under senare år har allt fler kliniska träningscentra för färdighetsträningetablerats för att möjliggöra en trygg och säker lärandemiljö med simuleringsmöjligheter förstuderande och personal. Klinisk färdighetsträning är en viktig del i sjuksköterskeutbildningenvid Högskolan Dalarna (HDa) där lärandemiljön på Kompetenscentrum (KC) kan bidra till enförbättring av lärandemiljön i den kliniska färdighetsutbildningen.Syfte: Syftet med denna studie var att undersöka sjuksköterskestudenters upplevelser viaskattning av lärandemiljön för klinisk färdighetsutbildning före och efter inrättandet avKompetenscentrum.Metod: Studien genomfördes som en enkätundersökning med kvasiexperimentell design.Enkätens baserades på Saarikoski och Leino-Kilpis mätinstrument CLES där frågeställningarom lärandemiljön modifierades med hjälp av Delphimetoden utifrån de tre olikadimensionerna: utbildningsmiljö, relation och lärarens roll. Mätningen före inrättandetgenomfördes under hösten 2010 och mätningen efter inrättandet genomfördes hösten 2011.Totalt ingick 266 sjuksköterskestudenter i studien varav 198 (74 %) besvarade enkäten.Resultat: Sjuksköterskestudenter skattade upplevelsen av lärandemiljön mer positiv efterinrättandet av Kompetenscentrum där resultatet visar en signifikant högre skattning i 8 de avde 16 frågorna. Sjuksköterskestudenterna skattade att de upplever att utbildningsmiljön är merverklighetstrogen, de är mer nöjda med färdighetsträningen samt att den inspirerar dem till attarbeta som sjuksköterska. Att relationen mellan dem och läraren bygger på respekt och att detär en mer positiv atmosfären under färdighetsträningen.
