1. Extending the tracks : A cross-reductionistic approach to Australian Aboriginal male initiation rites
Abstract : The thesis stresses two points regarding mandatory initiation rites where a young person is introduced into adult rights and obligations: first, that a poly-angular approach is necessary to get a fair picture of rites in general and initiation rites in particular, second, that each culture, into which a young person is initiated, contributes in a very special way to the design of the initiation rite. Therefore, a survey of some modes of interpretations is presented, after a description of Australian Aboriginal culture from early contact periods and a summary of recurrent themes in the Aboriginal male initiation rites.

2. Nanostructures Studied by Atomic Force Microscopy : Ion Tracks and Nanotextured Films
Abstract : The work presented in this thesis concernes two sorts of nanostructures: energetic-ion-impact-induced surface tracks and gas-deposited WO3 nanoparticles. Our aims to characterise these nanostuctures and understand the physical principles behind their formation are of general interests for basic science as well as of the field of nanotechnology.

3. Blood on the tracks : Life-course perspectives on health inequalities in later life
Abstract : The overall aim of the thesis was to explore social inequalities in: a) mortality during mid-life, b) health in later life, and c) old-age mortality, from a life-course perspective. The studies are based on longitudinal Swedish survey and registry data. READ MORE

4. Ion Tracks for Micro- and Nanofabrication : From Single Channels to Superhydrophobic Surfaces
Abstract : A method is described for preset-count irradiations between 1 and 100 ions singling-out individual ions from an ion beam with more than a billion ions arriving per second. The ion tracks are etched in a conductometric system with real-time evaluation of the acquired data. The etch process can be interrupted when reaching a preset channel diameter. READ MORE

5. Modelling the acoustic performance of slab tracks
Abstract : Transport is a major contributor to anthropogenic greenhouse gas emissions. Railway transport has a small footprint compared to other means of transport. This is one reason for the construction of new high-speed railway lines world-wide. READ MORE
