This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

The food prices in Finland and Sweden have been a subject for discussion for several years back in time. From the opponents against further European integration one have often heard that the EU and EMU entrance have made an negative impact on the food prices. This study show us that the impactof the entrances was extensive in the short run but rather finite and insignificant in the long run.Other important factors that describe why food prices fluctuate is also discussed. The mainconclusion is that other factors than the EU and EMU entrance should be seen as more likely whenit comes to the development of food prices. The essay is principally based on quantitative statistics of food prices, analysed in the light of economic theory..

The purpose of this study is to analyze how the parties (USA, Great Britain, UN and the European Union) legitimize their intervention in Bosnia-Herzegovina as seen from without the conceptions of sovereignty and intervention. USA and the UN have legitimized their intervention on security reasons. The American president, George W. Bush, claimed that democracies never engage in war with each other and that democracies were prosperous just because they were democracies. According to the president, that is why it is important to democratise the whole Balkan region to protect the international community from terrorism which grows in unstable and undemocratic states.

Background: Animals have been shown to have a positive effect on people. The nursing science approach says that a person can experience well-being despite illness. The positive attributes of animals can be used in health care to help ill people experience well-being. An animal-assisted intervention can be a form of activity or therapy involving pets (AAA / AAT) or horses (EAT).Aim: The purpose of this study was to elucidate how animals in health care promote well-being for people with long-term illness.Methods: Literature review based on fourteen original scientific articles, with both qualitative and quantitative approach.Results: The compilation of the results led to four main categories with two subcategories respectively. These were: Physical aspects with subcategories Physical well-being and Bodily functions; Psychic aspects with subcategories Psychic well-being and Reduced psychiatric symptoms; Existential aspects with subcategories Quality of Life and Safety; Social Aspects with subcategories Social behavior and Relationships.Discussions: Review and discussion of the selected method.

This paper examines the European Commission?s, newly established, ?Register of interest representatives? The analysis is divided in two parts, first I analyze the registers purpose, the kind, and detail, of information it contains and the different kinds of groups that are supposed to register. After that I analyze the organizations in the register more thoroughly, using a database of my own creation. The database was constructed with information drawn from the register, as well as information from external sources. Regarding the design and purpose of the register, I find that improvements in the design are needed, if the register is to fulfill its purpose.

Important issues for the local authorities are what to do with the sludge produced insewagetreatment plants. The tax for landfill leads to higher costs with 250 SEK/ton. On the 31December 2004 it will be forbidden to landfill sludge.In Sweden the yearly production of sludge is 240 000 tons, counted as DS. The phosphorouscontent is 3 % in sludge. The total yearly production of sludge gives 6000 tons of phosphorous.

Ett mönster är uppbyggt av ett motiv som upprepas. Denna upprepning kan fortsätta i all oändlighet. Hållbar antyder långsiktighet. Mönstrets övergripande egenskap är oändlighet. Hur kan denna egenskap hos mönstret nyttjas inom mönsterdesign för att främja hållbar utveckling? Det här kandidatarbetet undersöker mönsterdesignens möjlighet att verka för hållbar utveckling genom att se till begreppet mönster ur ett bredare perspektiv, samt i relation till design för hållbar utveckling.

Purpose: The aim with the report is to investigate if the South East Asian customer on the food processing market base their investments on Total Cost of Ownership and if so, which are the cost drivers considered most vital. Moreover, do these cost-drivers diverge from the perception FP Ltd has, and if so, can a Total Cost of Ownership-model help to achieve a mutual understanding? Methodology: First a descriptive approach will be taken, identifying FP Ltd?s employers? perception on how to meet the customer. This will later be compared to our empirical findings of the actual customer behaviour in Thailand and Vietnam. Thorough analyse of the gap between the two parts will give us the outcome whether or not FP Ltd will have any use of presenting a quantitative model justifying their higher price.

Göteborg Energi AB är ett bolag med höga ambitioner att säkerställa ett stabilt distributionsnät för sina kunder. Med ett säkerställande följer åtgärder i form av beräkningar för komponenter som transformatorer av olika märkeffekt, hög- och lågspänningssäkringar och andra kritiska skyddsanordningar som t.ex. reläskydd. Vid ett flertal tillfällen under de senaste åren har det uppmärksammats en problematik där ett fel i lågspänningsnätet har löst ut anslutande transformator. Felet har grundat sig en svag selektivitet mellan transformatorsäkring och lågspänningssäkring.

The purpose of this essay was to investigate the procedure surronding the abolition of the Statarsystem as well as trying to see possible motives for this abolition. In oder to do so different records from Svenska Lantarbetarförbundet and Svenska Arbetsgivarföreningen were examined. It soon became apparent that the procedure itself was not to hard. Both parties wanted the system to stop. In short, Svenska Lantarbetarförbundet´s motives were that statare did not receive a good social status and also that the system smothered statarna.
