Concrete is one of the world?s most common construction materials and is composed of 70-80 % stone material. Today crushed stone is used as aggregate in concrete in order to replace natural aggregates due to strong environmental reasons. Stone crushing yields flaky material and in this thesis studies are made on the flaky particle shape and how it influence properties of concrete such as workability, rheology and strength. The concrete recipes used in this thesis have fixed values, the only variable is the flakiness of the crushed stone.

In my study I have participated at the Fifth Dimension / Active Worlds site in Villa Gymnastiken in Ronneby, where I have worked both as an assistant to the project leader and as a researcher, but also as a participant together with the children. The children are working in a virtual world called Femtedim, created in a internet-based program named Active Worlds Education Universe. The Femtedim-world are bridging together two physical worlds in Ronneby and Copenhagen. My main focus is on an intervention that occurred in the 12th of March when the research-team in Copenhagen, which runs the project in Denmark, decided to create a new challenge for the children since some of them started to get bored. They added gravitation to the Femtedim-world, which lead to a few different reactions among the children. Most of the children didn´t like it and were very hostile towards the idea that they would not be able to fly around freely in the Femtedim-world.

This essay has it purpose to view the assessment and grading in physical education in the Swedish school.

In order to decide how democratic the examined countries are the democracy index constructed by The Economist is used. Besides the two central theories the purpose is also to explain why these variables could affect growth and to examine direct and indirect effects. Indirect effects mean that one variable affects another variable which thereafter has an impact on economic growth.34 OECD countries are compared in order to investigate whether education and democracy are strongly correlated with BNP per capita. Therefore a statistical design is used as method.The empirical results suggest that there is significant correlation between democracy and economic growth.
