Etanolmarknaden i Brasilien : etanol som fordonsbränsle
According to the EC fuel regulations 2 % bio fuel has to be blended in all fuel by the year 2005, and 5.75 % by the year 2010, which means ethanol for gasoline driven vehicles, so there will be a substantial demand for ethanol. Brazil already has an established industry for producing ethanol and is the leading producer and exporter of fuel ethanol. My purpose with this paper is to investigate why Brazil decided to develop ethanol production on a large-scale operation and to find out today?s situation.

Känslan av att inte räcka till : en essä om tid, närvaro och förskolebarn i behov av särskilt stöd
In this essay I consider a self-experienced dilemma, and review how I, as a preschool teacher, treat a child with special needs. With the support of literature and theory, I can, with an essay writing approach, reflect and analyze the dilemma. In this way I will examine my practical knowledge and personal experiences of a complex situation. I want to examine whether children with special needs who are included in regular preschool activities, really get the support they need and deserve. Do educators have the conditions and does preschool have sufficient resources to realize this? Do educators have sufficient knowledge of how children with special needs should be responded to? I want to find out how the included children's social development and self-image is shaped by the treatment they receive at the preschool.
Margin of Appreciation : en kulturrelativistisk doktrin?
With the collapse of the Soviet Union and the 9/11 attacks, the landscape of the freedom of religion has changed. The issues now facing freedom of religion varies greatly from the issues that the drafters of the universal declaration of human rights faced after World War II.In the light of the new issues that States face in the intersection of religion and societal interest, scholars have criticized the European Court of Human Rights to give too much leeway to the States in determining how the human rights should be implemented, by using the doctrine of margin of appreciation. Critics of the margin of appreciation claim that it is based on culture relativism and that the doctrine undermines the universality of the human rights. In order to decide if the margin of appreciation has indeed led to a relativization of the human rights I compared it to the jurisprudence of the UN Human Rights Committee and its use of the Syracusa principles. My conclusion is that the jurisprudence of the European Court of Human Rights cannot be considered to be based on culture relativism.

Analys av lageregenskaper utifrån mätningar i testrigg
Vertical hydropower units has a rotating mass of up to 1000 tons. For the generator and turbine to work well the rotating system is required to be centered in relation to the surrounding structure. This is achieved by means of radial bearings. The dynamic characteristics of these bearings have a strong impact on the overall rotational dynamics of the total system and thus influence the vibrations in the unit. At Vattenfall Research & Development in Älvkarleby ongoing research is taking place on how the bearing parameters should be represented in the rotor dynamic calculations.
