Träd och buskar i kantzoner : en undersökning av kanteffekter i några av östersjöregionens skogar
Around the world, forests are generally being fragmented and as plant populations decline in both sizeand number of individuals, the genetic variation will also decrease whitch in the end leads to totalextinction of the plant. In this paper, I wanted to investigate what specific species of trees and shrubsyou usually find in the edge and core habitats in some of the forests in the Baltic Sea region. I alsowanted to identify the edge effects and their sources and finally compare the results between thedifferent regions.The data sources used are derived from the ongoining research project Landscape structures, patterns ofbiodiversity and conservation strategies in the Baltic Sea region by Kari Lehtilä, Patrik Dinnétz ochTiina Vinter who have made a record of all herbaceous plant species in four randomly chosen forestregions situated around the Baltic Sea: Estonia, Skåne, Södermanland and Germany. I made statisticalanalyses, using the computer program R, concerning the distribution of species in the edge habitats ofthe forests as well as in the core habitats. I performed generalized linear models and then variationanalyses with the factors light and biomass in order to investigate wether edge effects might appear dueto these factors.
Direct-EGR tillämpat på HCCI
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.
Småvatten då och nu : en förändringsstudie av småvatten i Skåne och deras kväveretentionsförmåga
Wetlands play an important role in the ecosystem. They reduce the impact of flow flux in the drainage area, acts as upholder of biodiversity, as an esthetic and recreational component in the landscape and they have the ability to reduce nutrients such as nitrogen, and help preventing eutrophication in costal areas.The number of wetlands in Scania have, due to the intensified agriculture been reduced to maximize the area suitable for crops.However since the mid 80th the consequences of this has been acknowledged, and many wetlands have been restored.This master?s thesis aim to see what impact this development have had on wetlands in Scania over the last 60 years. And also look at some of those factors important for the efficiency of nitrogen removal in wetlands. During the process a detailed manual for inventories of this sort was created.The material used to execute the inventory of wetlands where aerial photographs over Scania from the 1940th, 1980th and 2000.
5 minuter till Luleå : en visuell studie av en stadsinfart
SUMMARYThe demands on the public environment are big and in particular on the environment of communication which we spend a lot of time in on our way to work, school etc. The city-approach is a road section that leads from the periphery of the city to the centre of the city, often through boring and meaningless industrial areas that displays the back side of the city to the voyager on the city-approach. The intentions of this thesis in landscape architecture has been to study one of the two city-approaches to the city of Luleå, the close surroundings and contextual position in the city and not at least give suggestions of ways how the city-approach can be changed, clarified and improved. The study of the city-approach has been made by studying literature that concern city-approaches and the architecture of roads in general. Studies of different analysis methods has been made to find appropriate approaches to work with the specific study of the city-approach to Luleå.

Strategier i Förvärv : Är det där skon klämmer?
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.

Digitalisering av bilder vid två museer
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.
Logopeder och barn i interaktion : Samtalsanalys vid behandling av språkstörning
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.

Ett verk blir kosmopolitiskt : Representerar Louise Bourgeois verk Maman någonting "universellt"?
The aim of this work is to give an example of how archaeoacoustics can broaden our understanding of archaeological remains and to further contribute to the almost non-existing research of ringing stones. With a theoretical discussion about sound from three different perspectives and by means of using different kinds of analysis, this essay will show that there are unknown relations between the three known ölandic ringing stones and the cultural landscape of Öland. Possible patterns in the placement of the stones and the possibility of the sound in this soundscape will be investigated. The essay will also suggest a resonant stone typology and discuss the necessity of one. Finally, the intention is also to shed new light upon the discussion on what the uses of the ringing stones might have been..

Delta på lika villkor? : En studie om ekonomiskt utsatta barns skolsituation sett utifrån ett lärarperspektiv.
The aim of this essay was to create an understanding of teachers strategies to respond to children in economic hardship in school and if these children can participate on equal terms in school. To examine this, we chose to do semi-structured interviews which is a qualitative method. Eight teachers were interviewed from four different elementary schools. In our interviews, we found that all the schools both had elements of inclusion and exclusion, which can result in both equal and unequal terms for participation in school. We also found that the school with the most students in economic hardship had the most inclusive strategies.
