Optimering av driftläggningar i Fortums nät

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

Inkludering av invandrade barn i förskolan : En kvalitativ undersökning om hur invandrade barn blir inkluderade i förskolan

The purpose of this study is to improve our understanding of how immigrant children become included in some preschools. With immigrant children we meant those children who immigrated to Sweden. In order to achieve our purpose we have chosen to find out some educators' perceptions about inclusion and which strategies they use to include immigrant children.To realize the study purpose, we have chosen to use qualitative interviews as a method. We conducted interviews with sex educators who worked in two preschools. The empirical materials we got from the interviews formed the basis for our analysis.The analysis of our collected data was based on our theories and conceptions.

Förskolans fysiska inomhusmiljö ? en miljö för barns utveckling och lärande : En intervjustudie med åtta verksamma förskollärare

Syftet med detta examensarbete är att undersöka förskollärares uppfattningar om hur den fysiska inomhusmiljön bör utformas för att stimulera till barns utveckling och lärande. Studiens teoretiska utgångspunkt hämtas från det sociokulturella perspektivet, där människan ses som oskiljbar från den kultur och det sociala sammanhang hon ingår i. Miljön ges ur detta perspektiv en stor betydelse, då människans ömsesidiga samspel med omgivningen och miljön påverkar möjligheterna till utveckling och lärande. Genom kvalitativa intervjuer har det i resultatet framkommit att förskollärare anser att den fysiska inomhusmiljön, för att stimulera till barns utveckling och lärande, bör utformas så att den är upptäckande, utmanande och utvecklande. Vidare framhålls att tillgänglighet är en viktig aspekt som förskollärare tar hänsyn till och att den påverkas av en rad faktorer.

Hur l?ngt bort n?r v?rldslitteraturen? En l?romedelsanalys om representationen av sk?nlitter?ra f?rfattare som skrivit p? andra spr?k ?n svenska inom gymnasiekurserna Svenska 1 och 2

The purpose of the study is to contribute knowledge about the representation of fiction authors who have written in languages other than Swedish in educational school books within the Swedish subject. This is done in relation to the school's promotion of cultural diversity, a globalized world and to the Swedish curriculum. The study is a combination of a qualitative and a quantitative analysis that takes its starting point in six educational books for the courses Swedish 1 and 2. The analysis shows that all study materials include a broad representation of authorships from Europe and the USA. The selection of authors from other parts of the world is, however, limited.

Var är kvinnorna i litteraturhistorien? : En komparativ studie av hur kvinnliga författare framställs i två upplagor av Svenska Timmar ? litteraturen

This essay examines how female authors are described in the literary canon of two differenteditions of the Swedish education material on the history of literature: Svenska Timmar ?litteraturen. The purpose of this study is to investigate whether the depiction of femaleauthors has changed from the first edition (1991) to the last edition (2012), and how thesechanges correspond with the curriculums Lgy70 and Lgy11.The study is quantitative as well as qualitative. The quantitative part of the study showsthat the percentage of female authors has increased in the 2012 edition. A greater number offemale authors are also portrayed with pictures and headings.

?Naturvetenskap finns ju överallt? : En kvalitativ studie av hur förskollärare på småbarnsavdelningar på Reggio Emilia inspirerade förskolor  ser på arbetet med naturvetenskap

The purpose of the study was to determine the attitudes of the teachers of Reggio Emilia inspired preschools concerning the science work with children between the ages of one and three, as well as their opinions on how the physical preschool environment and the choice of materials influence their scientific work. The study was conducted in three departments of two different kindergartens. Although both kindergartens called themselves Reggio Emilia inspired, their working methods and their environments differed largely. None of them were originally built as Reggio Emilia inspired preschools. One of the kindergartens strived to design their indoor environment the same way as the preschools of Reggio Emilia are constructed, there for they were setting up different stations where the children themselves have the opportunity to explore various scientific areas.

100g glättat : En ideologikritisk analys av neoliberalismens inverkan på fristående gymnasieskolors marknadsföring

Swedish school system is today victim of facing competition. Today sees the school leadership the students like customers whom they depend to operate their school. But I have asked myself, what will be the new students see and how much this spectacle in both money and time that project will cost for the municipality and school teachers. The question is if whether the school will be better when the competition becomes school or just better marketed? I'm interested in how clearly ideologies emerge in schools brochures if we study them at critically and analytically way.

En effektivare källsortering för bättre materialutnyttjande - en behovsanalys

The waste fractions offered to households in Sweden differ depending on where you live. The responsibility for the waste are grounded by the Swedish law where the municipality are responsible for the collection of household waste and FTI are responsible for collecting all packages and papers that the households sorts out. A new waste regulation is under consideration where the responsibility for the household waste may change. The bulky waste from households is collected at recycling centers where the households leave it in different containers for different fractions. These recycling centers are formed different and the fractions offered in them also differ depending on in what municipality they are located.

Do CEOs Get Paid for Performance?

Agency theory describes the conflict of interest between the principal (stockholders) and the agent (CEO). Aligning the incentives of executives with those of the owners is the most direct way to mitigate the agency problem. If there is no meaningful link between CEO compensation and company performance, it is doubtful that the large sums of assets in public corporations are being managed efficiently. In theory the solution is simple reward the CEO when shareholders wealth increases. The purpose of this paper is to investigate if there is a relationship between company performance and CEO compensation among Swedish companies, in materials and information technology industry.

Ronningsgift

This thesis examines the sheep shed called Ronningsgift, and its historical functions and geographical location. The study aims to make a comprehensive gathering of the existing knowledge and to shed light on new theories about the history of Ronningsgift. This is done through desk research including literature and archive search, as well as an investigation and description of the construction and materials, and an interview. Further, I got the opportunity to take part of the results of two C14 samples from Ronningsgift. The literature and archive search shows that the most common theory of the historical function is as a guest house (g?ststuga/h?gstuga) or more traditionally called, Malst?ue/Malsteuvu.

De fina skillnaderna : Vem och vad signalerade status i klädedräkten, Öjaby och Virestad under 1780-talet.

This study examines patterns of consumption during the 1780s in Öjaby and Virestad parishes. I have examined the clothes and jewelry in estate inventories using the concept of status. Then I have used Pierre Bourdieu's theories to understand fashion mechanisms.I have identified five different groups, each distinguished by their formal wear. Men have similar clothes but in Virestad they have more items and more silver. Four people were divergent, they choose other materials and models.
