16. Species interactions in streams - effects of predation, competition and ecosystem properties
Abstract : Stream ecosystems are dynamic and they have an inherent environmental variability. Organisms that live in streams are adapted to the continuously changing environment and the presence or absence of species are determined by their environmental requirements, while abundance is most often affected by interactions, such as competition and predation, with other species that are found in the same habitat.

17. Unifying first-principles and model approaches for strongly correlated materials : Interplay between long- and short-range correlations
Abstract : In materials with open 3$d$ and 4$f$ shells the valence electrons are relatively localized around the atoms which leads to large electron-electron correlations. These, so called strongly correlated materials, exhibit many intriguing properties such as high $T_c$ superconductivity, colossal magneto-resistance and heavy fermion behaviour. READ MORE

18. Discovery of Novel Receptors for Lipid Mediators - a study leading to the identification of receptors involved in metabolism and the immune system
Abstract : Intercellular communication is of crucial importance in regulating physiology and G-protein coupled receptors (GPCRs) have evolved as an important mechanism in this process. Of the approximately 800 human GPCRs, about 160 are still considered to be “orphan” receptors for which an endogenous ligand remains to be identified. READ MORE

19. Assessing Holocene and late Pleistocene geomagnetic dipole field variability
Abstract : Palaeomagnetic studies of continuous geological archives and archaeological artefacts are required to reconstruct geomagnetic field changes beyond the range of historical observations. In this thesis I assess the reliability of sedimentary palaeomagnetic data and Holocene dipole field reconstructions. READ MORE

20. Allergy to pets : molecular approaches for improved diagnostics and vaccination
Abstract : Allergic diseases are a major health problem, affecting up to 30% of the population in affluent countries. Domestic pets such as cats, dogs and horses are among the most common agents of IgE-mediated allergies. READ MORE
