16. Numerical simulations of long spark gaps – lightning attachment and its application
Sammanfattning : The Licenciate Thesis presented here is a research work on numerical simulations of two different electrical phenomena: Long gap discharges under switching impulses and the lightning attachment process of positive upward leaders. The development of a positive upward leader and the process of progress of a discharge in long gaps are composed of two intertwined physical phenomena, namely the leader channel and the corona zone.

17. Lärarstudenters digitala studievardag : Informationslitteracitet vid en förskollärarutbildning
Sammanfattning : This dissertation reports on an investigation into how digital tools are used, negotiated and given meaning in Swedish pre-school teacher education. The overall aim has been to create a deeper understanding of how students’ information literacies are enacted when digital tools are used and appropriated in the daily life at a pre-school teacher education, in relation to conceptions of the digitalisation of teacher education in national policy.

18. Health and Nutrition in the Tarahumara of Northern Mexico : Studies among Women and Children
Sammanfattning : Belonging to an indigenous group in Mexico is usually associated with poor health, mainly as the result of social isolation from the mainstream society. The Tarahumara are no exception. They constitute the largest indigenous group in northern Mexico and one of the most marginalized ethnic minorities in North America. LÄS MER
19. Numerical Simulations of Long Spark and Lightning Attachment
Sammanfattning : The research work presented here is concerned with numerical simulations of two different electrical phenomena: Long gap electrical discharges under switching impulses and the lightning attachment process associated with positive upward leaders. The development of positive upward leaders and the progression of discharges in long gaps are attributable to two intertwined physical phenomena, namely, the leader channel and the streamer zone.

20. Understanding the polarization of responses to genocidal violence in Rwanda
Sammanfattning : This doctoral dissertation is concerned with identifying factors that are important in explaining popular support for genocidal violence in Rwanda. It focuses on former communes, Giti and Murambi, to investigate why Giti successfully resisted the genocidal violence, while Murambi fell prey to large-scale violence. LÄS MER
