Genom statistisk analys utvärdera geometriska parametrars påverkan på ett XPI- cylinderhuvuds snurrtal

This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.

Den moderna matnörden

Det finns många aspekter som påverkar människors matval. Smak och preferenser är endast några av flera aspekter som styr vad vi äter. Kultur, samhälle, familj, vänner och ekonomi är några av de saker som spelar in när vi väljer mat. Därmed medför själva matvalet en identi- tetsaspekt, vi är helt enkelt vad vi äter. Idag har vi via sociala medier stora möjligheter att dela med oss av våra åsikter och visa glimtar av vår tillvaro för vår omgivning och mat är ett van- ligt återkommande ämne i blogginlägg och ett motiv för bilder.

Den nationella värdegrunden inom äldreomsorgen:några enhetschefers intryck

The aim of this text is to study how sectional managers in the care of the elderly work so as to promote basic human values. Semi-structured interviews generated qualitative data from five sectional managers. A hermeneutical approach was applied for interpreting the interviews. The result shows that the respondents are conscious of the fact that it takes a lot of long term work before a change in current procedures will happen. Also, the common everyday principles of work and basic values will continue to be part of the care of the elderly.

Projekt. En vanlig arbetsform.

The aim of this Master?s thesis is to investigate the factors of children?s voluntarily reading in their spare time. We also want to know if the children choose non-fiction books for their voluntarily reading. The method as well as the empirical basis of this study is qualitative, with interviews of twenty-eight children in ages between 9 and 12 years. We conducted nine interviews with 3?4 children in each group.

Intranät och dokumenthantering vid ett mindre till medelstort företag En fallstudie

The aim of this masters thesis is to learn how an organization has solved its information management via intranet and document management. The purpose is to identify what different types of information are made available via an intranet, how this information is structured and what functions the intranet includes. Conventions, directions and advice about intranets and document management were studied, with the purpose to compare whether the systems of the company correlate with these. Other issues considered in the thesis, are how the employees of the organization use the intranet and how the document management is organized. To get an understanding of these questions the structure and functions of the intranet were studied empirically and a questionnaire on what the employees need and use, concerning the intranet, was sent out to 130 employees.

Gränslandet mellan hem och förskola : en arena för gästfrihetens kommunikation

The purpose of this master thesis is to examine some pre-school teacher's and parent's perceptions about communication within the pre-school context and how this can be described in terms of conceptual dichotomy.The empirical investigation consists of a qualitative study, where data have been collected by interviewing two focus groups and one single parent.The main theoretical tools which the study uses as its premiss is Derridas' theory of hospitality and Habermas' theory of deliberative dialogues. The study also considers the conception of the intermediate domain as an arena for communication between parents and pre-school teachers, and further more the conception of stereotyping in social and cultural contexts.In order to explore these processes I have used the qualitative method of interpretation; Hermeneutic, also with a narrative approach to the analysis.The results and the analysis of the data show that the interviewed parent and pre-school teachers have a poor sense of knowing how much influence to give to each other. The parents were not satisfied with the level of open communication and how the pre-school teachers share information of the activities..

Samlingen som verktyg : Personal Information Management  och konstna?rers personliga samlingar

The study set out to find how artists organize and use their personal collections from a Personal Information Management (PIM) perspective, and how that use affects their practice and their art production. A secondary object of the study was to articulate the ways that personal collections are utilized as tools by creative users.  The empirical data consisted of five qualitative, semi-structured interviews with Swedish and Norwegian sound artists. The constant comparative method was used for analysis, and Activity Theory was used as a theore- tical framework for the study. The study concluded that artists? personal collections, while diverse in content and structure, serve the same functions as tools in creative processes, and that attention to the uses of personal collections highlight needs that could be better met by integrated PIM-functionality.

Kärlek, misshandel och trauma. En fallstudie om kvinnomisshandel och dess konsekvenser.

Male violence against women in close relations has in recent years received increased attention, however, only identified as a problem in approximately 40 years. It is now a social problem that is constantly increasing, but the identification of the phenomenon has been possible thanks to the research on the subject. The purpose of this study is to, from a woman's own story, identify psychological processes in connection with the assault. The aim is also to confirm previous research on the phases of the abused go through until decampment and identify possible consequences of violence against women. I also aim to answer the question regarding the assistance of individuals in extreme situations while getting back to society.

Kalciums och magnesiums inverkan på arsenikavdrivningen i virvelbäddsugnen : The influence of calcium and magnesium on the expellation of arsenic in the fluidized bed furnace

In the fluidized bed furnace at Rönnskärsverken, Skelleftehamn, sulphur-containing ore concentrates are roasted in order to remove about 50% of the sulphur in the incoming ore concentrate. This occurs in order to reach the goal of a matte containing 55% of copper in the following smelting process. At the same time as the ore concentrate is partially roasted pollutions as arsenic, antimony and bismuth are expelled. Earlier made thermodynamic calculations of equilibrium suggested that calcium and magnesium form stable compounds with arsenic and thereby inhibit expellation of arsenic in the fluidized bed furnace, an element that is undesired. The purpose of this thesis work was to gain knowledge of the mechanisms behind the formation of these stable arsenic compounds.

Förvärvsprocesser - vad köper biblioteken in och varför? En undersökning av förvärv gällande skönlitteratur på Lunds huvudbibliotek och fyra stadsdelsbibliotek

In this Master's thesis we investigate the collection management regarding fiction for adults. The apprehension of fiction has changed over the years. From the beginning it was considered to be mostly educational rather than being the purpose of entertainment. As for today these views are not opposites to each other. Regarding this we discuss the problem concerning terms of quality.

Förslag till ett ramverk för att evaluera funktionalitet i eCommerce-plattformar

In this thesis we have developed a framework of features associated with eCommerce platforms and then defined them. Thanks to our interviews with eCommerce-developers, we have been able to define multiple eCommerce features with the focus on an owner?s perspective. Much of the previous research in the area, takes a user perspective when the functionality of eCommerce-platforms have been assessed and evaluated. We have therefore taken an owner?s perspective in the evaluation of eCommerce platforms and therefore produced a suggested framework with key features associated with the owner's functions.

Hur blir man feminist i Sällskapet? : Vägar till ett politiskt radikalfeministiskt fält

This field study examines how politically active radical feminists have reached their position in a group called Sällskapet. The aim of the study is to examine different paths, with the purpose to gain understanding of how to become a politically active radical feminist. Also, processes of social recognition on the field are examined; what is recognized and what taste preferences and behaviors gain a lower value? The different paths to the feminist position have been examined through a qualitative method consisting of a mixture of interviews and participant observations. The question if the position in Sällskapet requires specific experiences has been analyzed through Pierre Bourdieu?s theoretical framework, with a particular emphasis on the concept of habitus, symbolic- and cultural capital.

Projektarbete som läroform : En kvalitativ studie av en förskolas projektarbete

The purpose of the study was to examine how teachers and children interpreted the project and understood its values. To this end, it was necessary to focus on four defining parameters which affect the investigation: structure of pre-school project work, content and delivery, the methods used by teachers during the project, which pedagogical documentation was used (and how), and how the project determined the approach, the curriculum goals and values. Using a qualitative approach, regular unsystematic observations were made over five days, during which three teachers, two pedagogues, two pre-school teachers, and one nanny from the same kindergarten were interviewed regarding children in three age groups: 1-2 years old, 3 years old, and 4-5 years old. The results of my investigation showed that the teachers were divided on how to apply the project as a working method. Children's active role in the pre-school project varied depending on the extent to which teachers adopted children perspective in everyday practice.
