Abstract:According to the curriculum of the Swedish school the pupils should develop their historical consciousness. The aim of this study was to find out which pupils develop this consciousness by listing to an historical novel, talking about that book and writing stories. The study went on for four weeks and the subject of the teaching was the Middle Ages. 28 pupils took part and a variety of methods were used: 1: questionnaire about the lives of the pupils, 2: Making observations of their attitude to the teaching and 3: story writing. The results show that the social background does not influence the development of an historical consciousness.

In a time when milk producing farm businesses face decline in profitability it is of great importance to examine how the situation can be improved. This thesis is a study off efficiency in milk producing farm businesses represented by Swedish, Dutch and German farms. The aim of this study is to investigate whether any differences exist between companies in these countries. Moreover, the study includes a mapping of a number of factors that determine how efficient milk production can be managed. This mapping is based on a literature review on prior efficiency studies followed by qualitative interviews with milk production advisors as well as a questionnaire sent out to dairy farmers in Sweden.

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.

Every year, KTH participates in the Shell Eco Marathon, a competition whose goal is to design a vehicle that can go as far as possible using only the equivalent energy of one liter of petrol fuel. This year, one of KTH?s contributions to this race is the Agilis prototype; a car powered by a uniquely configured HCCI-engine developed at the university. The engine is dependent of several subsystems in order to work properly, among other, systems for cooling and lubrication.Combustion engines are in need of a cooling system that reduces the heat developed during the combustion. In general, two main types of cooling systems are employed; either air cooling, where the outside of the cylinder is exposed to a flow of the surrounding air, ore water cooling, where water flows in tubes around the engine, and the heat are transferred by the water to the surrounding air through a heat exchanger.The purpose of the lubrication system is to prevent the friction that builds up in the interference between moving parts in the engine.

I Sverige står byggnader för nästan 40 procent av den totala energiförbrukningen och energibesparingspotentialen är enorm. Samtidigt dyker det upp mängder med aktörer som vill hjälpa fastighetsägare att energieffektivisera och allt fler energitjänster introduceras till marknaden. Möjligheterna för ett samarbete mellan fastighetsbolag och företag som erbjuder energitjänster har aldrig varit större, och en av dessa aktörer är energibolagen. Konkurrensen är dock hård och för att säkerställa sin konkurrenskraft på marknaden krävs effektiva samarbeten, där kundnöjdhet är i fokus, vilket i sin tur ökar behovet av kundkännedom hos energibolagen.Syftet med denna studie är att hjälpa energibolaget Elkraft Sverige att förstå olika fastighetsbolags energisituation och behov av energitjänster, samt rekommendera hur de bör utveckla sitt energitjänsteerbjudande för att kunna bistå dessa kunder på bästa sätt i framtiden.Detta gjordes genom att olika typer av svenska fastighetsbolag kartlades och analyserades med avseende på deras energisituation, beslutsfattande gällande energifrågor samt behov av energitjänster. För att samla in data genomfördes först en litteraturstudie, sedan semi-strukturerade intervjuer med högt uppsatta beslutsfattare samt en enkätundersökning.Slutsatsen blev att Elkraft Sverige bör finslipa sina befintliga energitjänster och komplettera sitt begränsade erbjudande genom att ingå externa allianser med kompetenta aktörer.

The rising demand for electricity and heat raises a big challange for the society and engineers. Many products have been introduced to the market to supply more energy to the energy systems. Absolicon AB is a Swedish company that develops and markets a combined heat and power generating product. The product, Absolicon X10, uses a parabolic trough to concentrate the radiation of the sun onto a receiver. The receiveris equipped with mono crystalline solar cells and is cooled by a circulating liquid media.

To create multifunctional buffer strips along a watercourse in an economically sustainable way requires consideration of many different factors. In this plan we have selected pollutant reduction as the main purpose of the buffer strip. We have also strived to achieve minimal income loss due to reduced production, increased biological diversity, good game preservation that leads to higher income from hunting, aesthetical satisfaction and possibility to profit from available subsidies. This is done mainly to make landowners/farmers more interested in creating buffer strips along water courses. As sand is the dominant type of soil in the area, the water course is less affected by surface runoff compared to if the soil would be clay or some other finer texture. Game preservation and subsidies have therefore been the main factors when establishing the width of the strip, because these require wider buffer strips in some cases.
