Transient driftförhållande blir allt mer intressant för forskare och tillverkare och de största svårigheterna är att minska emissionerna utan att påverka bränsleförbrukningen eller motorns respons vid gaspådrag negativt. Huvudmålet med det här examensarbetet var utvärdera olika metoder för att mäta NOx och antal partiklar med hög tidsupplösning för att möjliggöra studier av emissioner under transient driftförhållande.I arbetet har en Horiba MEXA 120NOx NOx-sensor studerats med avseende på linearitet, mätsäkerhet och responstid. Försök för att öka noggrannheten har också gjorts genom att kompensera för varierande skalfaktor för utsignalen och för responstiden.Ett spädsytem har arbetats fram för att ge hög tidsupplösning och god repeterbarhet. I detta ingick en Rotating Disc spädare och en två-stegs Dekati spädare. Spädsystemet var kopplat till en TSI Ultrafine Condensation Particle Counter 3025 A (CPC) och var nödvändigt för att hålla koncentrationen inom det mätbara området.

The proportion of elderly people in Sweden is increasing. Many of these live at home and as their age increases so does the likelihood of health problems and the need for support, medical attention and care. Personnel working with home help provide a large part of this care, including areas of home-based care that are the responsibility of the district nurse. The purpose of this paper is to describe how home-help personnel perceive their work in the area of home-based care, as their views are an important factor in the ability to provide a care system that funktions successfully. The method employed here is phenomenografic and nine subjects from a home-help group have been interviewed.

The aim of this study is to examine the interaction between a group of multilingual, twelve-year-old children, and three libraries. The children live in a suburb of a larger city. The three libraries are their school-library, the library in their suburb and the main library in the city. We have examined if and how the children use the libraries, what the libraries mean to them in their daily life and what their possibilities are when it comes to participate in and influence activities and collections at the libraries. We have pursued qualitative interviews with sixteen children in grade six and three librarians, working with multilingual children at the three libraries.

?African Solutions to African Problems? är en av Afrikanska Unionens nya ledord. Denna vilja om att ta mer ansvar för den afrikanska kontinenten och kunna agera som en säkerhetsaktör har resulterat i en ny säkerhetsdoktrin. För att kunna agera som aktör på den internationella arenan krävs att vissa förutsättningar existerar enligt en modell framtagen av Gunnar Sjöstedt. Dessa strukturella och institutionella förutsättningar kommer i denna studie att undersökas för att analysera huruvida AU kan agera som säkerhetsaktör.

In this study I have analysed the national tests in Swedish between the years 2006-2010. These tests are given to all students in the public schools in grade 9 and 10. I wanted to see if I identified an over-representation of a certain category of people in the texts given to the students. I analysed the texts from an intersectional perspective and I used primary Lena Martinsson (2007), Framtidens feminister and her categories and theories and Moria von Wright (1998) Genus & text- när kan man tala om jämställdhet i fysikläromedel?, and her gender categories in my study.

Vårt examensarbete bygger på vetskapen om skriftspråkets stora betydelse i dagens informationssamhälle och de larmrapporter som framkommit i media om att många idag lämnar grundskolan med bristande läs- och skrivförmåga. En anledning till det är att många av dessa elever tappar intresset för skolarbetet (SOU 2000:19). Som blivande pedagoger tycker vi att det är viktigt att försöka förstå vad det är som gör att lusten och glädjen för skriftspråksundervisningen avtar för alltför många elever De här grunderna, våra egna erfarenheter och litteraturstudier har gett oss inspiration att genomföra den här forskningsstudien. Syftet med vår studie har varit att undersöka elevernas uppfattningar om att skriva i skolan och vilka faktorer de anser betydelsefulla för att skapa motivation och engagemang i skrivundervisningen. För att få reda på elevernas tankar och känslor om skrivandet i skolan har vi valt att använda oss av en kvalitativ forskningsmetod.

The purpose of this study was to illustrate a parental perspective of children´s participation and quality of live through personal assistance. Important aspects of parents' experiences were highlighted based on how they experienced participation and quality of life for their children. We chose to use a qualitative approach in the form of four individual interviews with parents from different municipalities in central Sweden. The study was conducted with a narrative approach in which we used a holistic perspective. Parents' experiences were highlighted over time to create a complete picture.

The key purpose of this research has been trying to understand, and study how assyrian/syriac youth create their identity under the influence of two or several different cultures. We have also looked upon how different factors such as history, religion, language, family and school play a role in the youths identity development.We have used a qualitative method in our study where we have interviewed six assyrian/syriac youth. Because of their Christian faith the assyrian/syriac group has been forced to migrate from their countries to different parts around the world. In the new countries the group has been forced to create and live in a diasporaculture. The city Södertälje in Sweden has developed to become a metropole for this ethnic group where they have founded a substantial diasporaculture.

Term: Spring term 2007Study objects: Reitan Servicehandel AB, Vi-butikerna, ICA Sverige ABPurpose: The purpose of this study is to analyse how procurement is used as a strategy to achieve better competitive strength, within the retail food industry.Theoretical: The theoretical chapter illustrates different procurement organisations, multiple and single sourcing, brand equity, consumer behaviour and involvement, Efficient Consumer Response including supply chain and category management and finally Demand Chain Management.Method: For the case studies, three food retail companies have been interviewed: Reitan Servicehandel AB, Vi-butikerna and ICA AB. To illustrate how consumer behaviour influences retail food market, several secondary consumer research studies have been analysed.Conclusions: The results indicate that the procurement organisation can achieve a better competitive strength by a centralised organisation, which make it possible to improve conditions of terms when ordering higher purchase volumes. The sourcing strategies can improve a company?s power within the supply chain. All companies within the study had a very good knowledge about consumer behaviour.

We are in an emerging digital society where we are increasingly dependent on the mastery of IT and digital technologies to better carry out our everyday tasks. They cover everything from keeping in touch with family and friends to pay bills and declare. At the same time there are those who have not learned how to use the new technology and live their lives outside of the digital society. What happens to these people, in a society that is becoming increasingly digitized? Do they take harm by being in digital exclusion? It looks like this are issues that will not become less important as digital technology constantly changes.

The objective of this paper is to describe and analyze female irregular immigrants and their experience of how relationships with other people affect their lives and identity.A qualitative method is used in the study, because my main purpose is to analyse the respondents? lives and life experiences. The analysis is based on a symbolic interactionism perspective. The results are also analyzed based on previous research and the concepts underlying the paper; irregular immigrants, discrimination, power and identity.In summary, the respondents have a clear picture of how they live and experience their relationship to others and themselves and how this affects their lives and identity.Their experiences affect their lives and influence their behaviour and identity when they interact with others. Their own view of their situation means that they are afraid to seek care or report sexual abuse, threats or other similar conditions.

The state of health in Sweden demonstrates a high average length of life at the same time as diseases, due to luxurious living, grew into more and more widespread public health problems. Finding out that information is not enough to get man to live healthy has been conducive to a pedagogic based health education. An illustration of such an education is Public health pedagogy at the University of Kristianstad. The question is, does this education correspond to the new claims that society lays to health work? Our purpose was to throw light upon how individuals, qualified as public health pedagogues, look upon their work on one hand and how different clusters of thought from their study programme are conceived as activated in their professional exercise on the other.

The purpose of this report was to compare two different options for expanding of an existing pig farm. For the time being there are low prices within the agricultural market of pig production, and it is interesting to see if it is worth expanding or not. The two different options this report is based on are: expanding from a herd with 50 sows in breeding gilt production to a herd with 100 sows in breeding gilt production (option 1), or expanding to a herd with 140 sows in breeding gilt production (option 2). The number of pregnant gilts produced per year will stay the same for both alternatives; about 300 pregnant gilts per year. The rest of the breeding gilts will be sold at a weight of 25 kg. The pigs that are not sold as breeding gilts (e.g. castrates, and female pigs that are too small or that have disorders) will be kept on the farm as growing-finishing pigs until 120 kg of live weight, and then sold to the slaughter house. By using the existing buildings, even after the expanding, the investment costs, and thereby costs for housing, were kept as low as possible.

I både våra egna erfarenheter och i forskning blir det tydligt att förskolepersonalensinteraktion med barnen på förskolans gård varierar i omfattning. Det här innebär att barnen påförskolans gård har olika förutsättningar till ett utökat lärande genom personalens interaktion.Det finns forskning kring personalens interaktion med de yngsta barnen på förskolegårdenoch hur den här interaktionen kan stötta barnens lärande. Dock saknas det forskning kringpersonalens interaktion med de äldre barnen på gården.Det här examensarbetet tar sin utgångspunkt på förskolans gård som ett socialt sammanhang,hur personalen interagerar med de äldsta barnen på förskolans gård och hur detta kan stöttabarnens lärande. Den vetenskapsteoretiska utgångspunkten är mikroetnografi och hela studiengenomsyras av Vygotskijs teori om lärande där stöttning och interaktion är betydelsefullanyckelord. Resultaten har framkommit ur empirin som består av videofilmer ochfältanteckningar vid till viss del deltagande observation av en förskolans utomhusvistelse, därbarnen är 3-5 år.
