Laser Shock Peening (LSP) and conventional Shot Peening (SP) are processes that aim to improve the surface properties of a workpiece by inducing compressive residual stresses. The peening processes also cause martensitic phase transformation in austenitic steels. Interestingly, experimental studies report significant differences in martensite content depending on the used peening process. This stu

As climate-related issues are important and concern all aspects of the built environment, there is a need to better understand the motives underlying household recycling behavior. The purpose of the present study is twofold: to investigate factors important for explaining the recycling behavior of young people and to explore respondents’ own ideas regarding barriers to recycling. This paper report
Due to insufficient knowledge on preschool teacher reporting obligations, studies show that fewer reports are made regarding children that might need help. The aim of the study was to illustrate how preschool teachers interpret and apply the law on reporting obligations in preschool activities and to illustrate the collaboration between preschool and social services. What does preschool teachers t
Despite discussions in Swedish education that English teaching in Sweden does not provide students with relevant contents that support their learning and motivation, no measurements have been made when it comes to the connection between Swedish students’ L2 motivation and pedagogy. The study at hand used a measure of self-determination to examine the L2 motivation of 159 Swedish upper secondary sc
Students often use incoherent strategies in their problem solving involving force and motion, as revealed, e.g. when they are asked to draw force diagrams for amusement rides involving circular motion, whether in horizontal or vertical planes. Depending on the questions asked, assignments involving circular motion can reveal different types of more or less correct and coherent strategies used by t
In 2015, Chumani Maxwele radical and controversial act of throwing human waste at the post-colonial statue of Cecil John Rhodes at University of Cape Town (UCT) came to give birth to a social media inspired student movement of #RhodesMustFall (RMF). The hashtag #RMF came to fuel protest towards the removal of the Rhodes statue at UCT due to its symbolic representation of white supremacy. The prote
