The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of lowNOx, low particulates and high efficiency. Due to its homogeneous charge, where thecombustion starts almost simultaneously from a number of points in the combustion chamber,only lean mixtures are possible to burn because of the resulting rapid combustion, which is muchfaster than the combustion in an SI-engine or a diesel engine. When richer mixtures are used thecombustion will start earlier and also be more violent.To phase the combustion later and lower the combustion speed, external cooled EGR can beused. The EGR-system used in this thesis uses a divided exhaust channel where one channel andits corresponding valve are used only for transporting EGR back to the intake system.Consequently the EGR-valve is connected to the intake pressure. This system is called Direct-EGR (D-EGR).Engine tests verified that the CA50 indeed is phased later when cooled EGR is used.

Bakgrund: Med bakgrunden av företags behov att utvidga sin verksamhetssfär, har företagsförvärv blivit alltmer frekventa och mer omfattande. Speciellt i branscher med snabb utveckling såsom IT-branschen, är detta av aktualitet. Med förvärvsvågors uppkomst, har även ett stort antal av dessa förvärv resulterat i misslyckande snarare än expansion. Förklaringen till detta är mångfaldig och kopplas till områden kring före, under och efter förvärvet. Det som förväntas av ett förvärv, är synergieffekter, det vill säga förmågor av förvärvsobjektet som bidrar positivt till moderbolagets verksamhet.

The aim of this thesis is to describe digitization of images in two Swedish museums. We want to examine their reasons to digitalize; the administrative and organizational aspects of their work and how they handle the problems of preservation and access to the digitalized images. These problems will be examined through our main questions: Why do the museums choose to digitize their image collections? How are their work organized in terms of staff and economical matters? What kind of software do they use, and which technical solutions do they choose? Which preservation and access strategies for ensuring long-term preservation and access of the digital images do the museums work with? How do the museums select material for digitization? How do they handle the matter of discarding of materials? The study was conducted both by reading text material and interviewing personnel at the two museums. The museums? main reasons for digitization seem to be to protect fragile materials from deterioration and provide greater access to the collections.

Speech intervention for children with language impairment aims to both strengthen specific language skills and to reinforce the ability to participate in interactional contexts. Children with language impairment often have problems in interaction; therefore the contributions of the conversational partner are of great importance. Thus, the demands are high on the speech and language pathologist (SLP) for sense and cohesion in intervention. The aim of the present study was to examine how SLPs and children with language impairment interact in language intervention. An approach influenced by Conversation Analysis was used in order to identify various phenomena that occurred, and their effect on the structure of the interaction was analyzed.Four SLPs, two men and two women, were enrolled in the study.  They participated in intervention with two children with language impairment each, i.e.

Textbooks are the most dominant literature used in schools and are therefore an important source of information. Consequently, it is crucial that these are not misleading or biased and maintain a high quality along with a strict concordance to the School Department?s curriculum. The aims of this study have been to examine how Mormons, Jehovah?s Witnesses and Hare Krishna are presented in four religion textbooks used in senior high schools, as well as to examine what type of knowledge is being presented in terms of epistemology.

Although research on gothic fiction has given limited attention to children?s fiction, the last two decades have witnessed an increasing interest. To date the focus has been mainly on English literature with a recurring tendency to define children?s gothic fiction as a text corpus separate from gothic fiction in general. As a result, children?s gothic fiction has become isolated and is not considered as part of the gothic genre, neither the literature nor its adaptations.The aim of this study is to view children?s gothic fiction as an integral part of the gothic genre.

Temporary architecture is an alternative urban planning concept which has been adapted in many cities worldwide during the last decade. There is however no common definition for temporary architecture and it is diversely labelled and applied. In 2013 it also became publicly introduced in Stockholm via the approval of the city's first architectural guideline. Temporary architecture is presented in the guideline as a potential tool for exploring public spaces among other architecture related themes. The ideas for temporary architecture are ambitious and promising. The problem is that they are vague and leaves questions regarding performance unanswered.
