17. Transient Response of Grounding Systems Caused by Lightning: Modelling and Experiments
Sammanfattning : In order to achieve better lightning protection and electromagnetic compatibility (EMC) requirements, the needs for a proper grounding system and the knowledge of its transient behaviour become crucial. The present work is focused towards developing engineering models for transient analysis of grounding system with sufficient accuracy and simplicity for lightning studies. LÄS MER
18. Features of the Electric Fields Generated by Lightning with Special Attention to Positive Ground Flashes
Sammanfattning : This thesis focuses on the main processes in positive ground flashes and the distant lightning environment for both positive and negative ground flashes. It presents the characteristics of the preliminary breakdown pulses (PBPs), the characteristics of the electric field pulses observed during leader propagation, and the characteristics of the electric fields produced by the first and the subsequent return strokes.

19. Träffad av blixten eller långsam kvävning : genuskodade uttryck för depression i en primärvårdskontext
Sammanfattning : Depression is a common mental health problem in primary health care. One third of the Swedish population is expected to experience depression at some point in their lives. The understanding of depression has expanded, both from a lay and primary health care perspective. LÄS MER
