There have been changes in Earth?s climate system on both global and regional scale since the pre-industrial era and some of these changes are due to human activities such as the combustion of fossil fuels. This calls for the development of engines with a higher efficiency and less harmful emissions. One interesting concept is the Homogeneous Charge Compression Ignition (HCCI) engine, which has the advantages of potentially low emissions combined with high efficiency. However, HCCI with diesel fuel requires a relatively long fuel/air mixing time to ensure a "homogenous" charge.

Ståhlgren, Johanna (2010) Handledarnas och lärarnas roller under bedömningsprocessen vid APU (Instructors and teachers functions during the process of rating at the workplace training) Skolutveckling och ledarskap, 180 hp, Lärarutbildningen, Malmö högskola. Syftet med den här undersökningen är att jag ska undersöka lärarnas och handledarnas roller under bedömningsprocessen av den arbetsplatsförlagda utbildningen (APU) på Hotell och Restaurangprogrammet vid tre olika gymnasieskolor i Västra Götalands län, samt hur deras kommunikation sker. Jag har valt att göra kvalitativa intervjuer med både handledare ute på arbetsplatser och yrkeslärare på HR-programmet, eftersom jag då kan få så utförliga svar som möjligt och att de får chans att prata öppet om sina upplevelser och erfarenheter. I resultatdelen framkommer det att skolorna arbetar olika vid APU:n och att handledarna får olika underlag ifrån skolorna om hur de ska bedöma eleverna. Men det har skett förändringar och ytterligare förändringar kommer att ske då en bättre samverkan mellan skolorna i Västra Götaland är på gång. Handledarnas och lärarnas syn på kommunikationen vid APU skiljer sig också åt, då handledarna saknar en bättre kommunikation.

This Thesis is performed in cooperation with Kalmar Industries in Lidhult, Sweden. Theprojects main purpose was to develop a draft design of a test equipment. The equipmentwill simulate and valuate the drive-train and brakes at Kalmar?s bigger forklifts.The equipment will be designed so the wheels of the forklift are placed on two rollers;these absorb and affect the forklifts brake- and driving force. With this characteristic anup- and downhill can be simulated.

Mellanchefer är värdefulla när förändringar ska genomföras i en organisation. Dock är mellanchefers roll komplex och dessa tvingas ofta hantera konflikterande förväntningar, vilket kan orsaka problem i förändringsarbetet. Denna studie undersöker hur mellanchefer i en organisation som Posten arbetar för att hantera konflikterande förväntningar. Fyra roller beskrivs, genom vilka mellanchefer ger bidrag till förändringsprocesser. Rollkonflikt kan uppstå, om konflikterande förväntningar ställs på individen.

Background:Mental illness has increased in Sweden and the individuals seeking care expect to be met with respect. The way patients perceive themselves to be treated by health care professionals plays a central part to care and treatment of patients, and the patients experience will decide how future care will proceed. The majority of complaints from patients with mental illness suggest that the way they are treated in health care is inadequate. For people with mental illness it is crucial how they perceive themselves to be treated since poor treatment can lead to reluctance in seeking future help. Aim: The purpose of this study was to describe how people with mental illness perceive themselves to be treated in primary health care.

The theme of this essay is the principle of free access to the Swedish Public Libraries, and its aim is to fmd out the opinion of adult visitors of such libraries as regards the introduction of fees on the borrowing of books, already existing fees such as reservation fees, charges for interlibrary loans and charges for the late return of books.The main part of our survey comprises questionnaires that were handed out to 100 visitors at the Norrkoping City Library and 100 visitors at the Eskilstuna City and Provincial Library. In order to illustrate the fee problem from another angle, interviews with staff people from the two libraries were carried out A large part of the essay consists of material aiming to give a general picture of the subject, e.g. how the "free of charge principle" is tied to the Swedish library system, what arguments have been presented to maintain or reverse this principle, and a comparison of the relative situation in other countries. As the conception of popular education is so basic for the "free of charge principle", we also account for the idea of popular education.The result of our questionnaire shows, among other things, that 60,9% cannot consider paying for any of the free services offer by the libraries today, 21,3% answered that they could possibly consider paying for some of the services and 17,8% answered that they didn't know. 76% would rather pay for a library card than stop borrowing books altogether..

This essay investigates and compares the readability in two different schoolbooks: Eko Historia (the primary school grade 4-6) and Epos Historia (the upper secondary school). The questions of the survey are:- Which differences in linguistic and layout can be found between books meant for the primary school and books meant for the upper secondary school?- Are the texts easy to read according to the former research in readability?In order to answer the questions structural dimensions as lexicon, syntax, bounds between sentences and narrative voices have been studied. Also the texts disposition and typography have been examined.The results demonstrate that the book designed for the primary school has a verbal structure with an explicit vocabulary, lots of verbs and short sentences. A clear narrative voice gives an impression of spoken language.

Syftet med studien är att undersöka vilka roller Axel Oxenstierna och Johan Adler Salvius hade i det fredsförberedande arbetet inför och under fredskongressen i Westfalen, men även att utifrån Salvius brev till Oxenstierna undersöka hur deras relation såg ut under den aktuella tidsperioden. De uppgifter som framkommer i Salvius brevväxling till Oxenstierna angående deras relation, samt deras roller och uppgifter under de fredsförberedande åren 1643-1648 kommer därefter att analyseras och jämföras med hur detta har skildrats av historieskrivarna Gunnar Wetterberg och Sune Lundgren. De resultat som studien har frambringat visar på att både Oxenstierna och Salvius var innehavare av mycket centrala roller i det fredsförberedande arbetet, samt att deras tidigare relativt nära relation till varandra försämrades något under åren 1643-1648..

My study is about a preparation class in a selected municipality. It is based on the child¹s perspective, and it tries to highlight the school situation of new arrivals in a school where the majority of the pupils are of Swedish origin. The purpose of my study is to visualize how the education for newly arrived children is organized in the municipality, and to get an understanding of a range of student?s view of the schooling in the preparation class as an introduction to a regular class.To reach my goal, I have used qualitative methods, based on qualitative interviews. The interviews were made with six newly arrived pupils, and one interview was made with the deputy head of the school, which is in charge of immigrant education in the municipality.

Syftet med vår studie var att undersöka hur barn på förskolan upplever maktpositioner och roller i den fria leken med fokus på genus. Vi ville se om de rådande föreställningar som finns kring hur pojkar respektive flickor förväntas vara stämmer, då pojkar framställs som att ta mycket plats medan flickor kliver åt sidan. Genom både intervjuer och observationer har vi jämfört barnens uppfattningar med det vi såg i olika leksituationer. Studien utfördes på två förskolor under sammanlagt fem tillfällen. Resultaten visar att pojkarna oftast tog på sig roller som stora och starka medan flickorna intog mer lugnare roller.

The main environmental problem for aviation is the great amount of exhaust gases, mainly nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons - mostly "greenhouse gases" leading to climate changes. I decided to sort out what is being done to decrease these problems and what regulations there are concerning air pollution by the means of searching the internet and using publications from aviation authorities for current figures. I chose to scrutinize authorities on political, authority and company level, resulting in summarizing the work of UN and EU respectively, ICAO (International Civil Aviation Organization), JAA (Joint Aviation Authorities) and LFV (Swedish Civil Aviation Authority), and finally SAS, representing the airline companies. Conclusion that I have drawn are thatthere are regulations for air pollution, written down in ICAO's Annex 16, that are to be followed. Secondly, LFV are environmentally controlling their nineteen airports and since economy is an important reason for not giving priority to environmental issues in aviation emission charge and noise charge are added to the landing fees.

Background: Mental illness is a growing public health problem which can cause significant disabilities and lead to poor quality of life. As primary care nurses often are the first to encounter these patients they need knowledge to be able to respond appropriately to this group.Aim: The aim was to describe how the sufferer of mental illness experiences the introduction to primary care. Method: The literature review was based on the results of 11 scientific articles which were analyzed with the inspiration of a metasynthesis method.Results: Four categories emerged: the experience of being treated like a human being, the importance of a therapeutic space, the experience of time and availability as well as the importance of competent personnel and the importance of continuity. Patients described different aspects deemed important when encountering nursing staff. Conclusion: Patients experienced that they received good care when they felt listened to and seen as individuals with their own thoughts and feelings.

Bakgrund: I debatten har BSC då och då dykt upp som ett ersättningsinstrument till budgeten. Vad som inte alltid framgår är vilket eller vilka instrument som bär de roller som traditionellt bärs upp av budgeten. Syfte: Syftet med uppsatsen är att beskriva och analysera vilka roller som BSC och budgeten har tagit i styrkortsanvändande företag. Avgränsningar: Vi har valt att avgränsa oss ifrån den bransch där budgeten som styrinstrument kanske fått mest kritik, nämligen bankbranschen. Genomförande: Vi har gjort en förstudie utifrån vilken fyra företag har tagits fram.

Familjebildning är för många personer en central del av livet. Att bli adoptivföräldrar innebär en annorlunda process jämfört med det biologiska föräldraskapet. För att bli adoptivföräldrar måste man genomgå en utredning. Utredningen benämns som medgivandeutredning och innebär att socialsekreterare granskar om personer är lämpliga som föräldrar. Syftet med vårt examensarbete är att förstå hur adoptivföräldrar upplever en medgivandeutredning och hur de upplever att bli utredda av socialsekreterare.

The purpose of this study is to examine in what extent primary school teachers, teaching children in the age of 6 to 9, choose to use digital tools in their teaching of mathematics. I also want to examine what these teachers think, in terms of advantages and disadvantages, about using digital tools on their mathematics lessons. Finally I want to examine what skills they possess about digital tools.I am using a quantitative method to collect my data. The quantitative survey consisted of a questionnaire survey of ten questions that 38 primary school teachers have answered.The results of my study show that the teachers to some extent use digital tools when they teach mathematics and that the availability of various digital tools are generally good. But it turns out that the availability of tools is not a guarantee that they are used in teaching of mathematics.
