1. Development of cannabinoid subtype-1 (CB1) receptor ligands for PET
Abstract : Introduction: Abnormalities in brain cannabinoid subtype-1 (CB1) receptor concentrations and/or signaling pathways may be involved in a variety of psychiatric and neurodegenerative disorders. There is a strong need to image and quantify brain CB1 receptor concentrations in living humans under baseline and diseased conditions. READ MORE

2. Untangling ambiguities in the microbial fossil record : experimental abiotic and biological approaches
Abstract : Life on early earth has long been the topic of discussion for many researchers: how did it come to be? Which cells came first? Where can we find them? The most ancient rocks on our planet may hold some of the answers to these questions, but many may only be answered in laboratories. Chemical and morphological traces can be found from Archaean deposits, tantalisingly similar to modern day prokaryotes. READ MORE

3. The evolution of TOFu : Developing and utilizing neutron time-of-flight spectrometry of deuterium and tritium fusion plasmas at JET
Abstract : Considerable effort has been invested in attempting to generate electricity from the energy released in controlled thermonuclear fusion reactions, with a European fusion research roadmap stretching beyond 2050. Our current endeavors may culminate in a virtually inexhaustible, low-carbon energy source for future generations. READ MORE

4. The influence of climate and permafrost on catchment hydrology
Abstract : The cycling of water in the landscape is influenced by climate change on different time scales and in different directions regarding warming or cooling trends. Along with a changing climate, also the landscape and subsurface conditions, such as permafrost extent, may change in a long-term perspective. READ MORE

5. Phylogenetic Support and Chloroplast Genome Evolution in Sileneae (Caryophyllaceae)
Abstract : Evolutionary biology is dependent on accurate phylogenies. In this thesis two branch support methods, Bayesian posterior probablities and bootstrap frequencies, were evaluated with simulated data and empirical data from the chloroplast genome. READ MORE
