1. Palaeobiology and Chemostratigraphy of the Precambrian - Cambrian Transitional Beds on the Siberian Platform
Sammanfattning : Biological innovations during the Precambrian-Cambrian transition opened evolutionary gates towards the modem biosphere. Two interrelated aspects of this process are investigated. The first one is the ecological radiation and beginning of calcareous biomineralization in mollusc-like organisms (shelled molluscs, coeloscleritophorans, and hyoliths). LÄS MER
2. Mechanics of paper webs in printing press applications
Sammanfattning : The mechanics of paper is a difficult subject because paper is a unique material. It is very thin, flexible at bending, unstable in compression and stiff at tension. Dealing with paper we have to account for orthotropy and heterogeneities created during the manufacturing process. LÄS MER

Sammanfattning : .... LÄS MER
4. Nonlinear dynamics of strongly-bound magnetic vortex pairs
Sammanfattning : This work is a study of nonlinear phenomena in vertically stacked pairs of magnetic vortices. New dynamic regimes are uncovered with a decrease in the inter-vortex separation to below the lateral vortex-core size. LÄS MER
5. Materials prepared using graphite oxides : properties and applications
Sammanfattning : Graphite oxides are hydrophilic materials, which have attracted a lot of attention due to unique properties and possible applications. The current thesis includes studies of fundamental properties and applications of graphite oxides as well as materials prepared from graphite oxides such as graphene oxide membranes, defect-rich graphite oxide, reduced graphene oxide and activated reduced graphene oxide.
