Erkï arung Hiermit versichere ich, dass ich die Diplomarbeit selbständig und lediglich unter Benutzung der angegebenen Quellen und Hilfsmittel verfasst habe. Acknowledgements In the first place I thank my advisor Prof. Dr. Olaf Lechtenfeld for giving me the opportunity to be a diploma student in his group, for continuous support from his side during the whole period of the past twelve months an...

The properties of graphene can vary as a function of the number of layers (NOL). Controlling the NOL in large area graphene is still challenging. In this work, we demonstrate a picosecond (ps) laser thinning removal of graphene layers from multi-layered graphene to obtain desired NOL when appropriate pulse threshold energy is adopted. The thinning process is conducted in atmosphere without any ...

Community hospitals. Across the world, policymakers are considering options to reorganise the geography of healthcare delivery, renewing focus on community hospitals as a safe and efficient alternative for acute admissions. In a rural district in Norway, GPs have for many years been referring acutely ill patients to a local community hospital, and, in Social Science and Medicine, researchers ga...

The FSCBG aerial spray drift and deposition model predicts the dispersion of material released from aircraft into the atmosphere, and particularly downwind from the release point. The effects of aircraft wake structure, droplet evaporation, local meteorology, penetration through forest or agricultural canopies, and prediction of ground or canopy deposition, air dosage, and concentration are all...

Hydrogen is the most environmentally friendly fuel and can be efficiently used for stationary power and mobile applications. When burned or oxidized, it generates water as the only emission (small amounts of NOx are generated during the combustion process but can be controlled to very low levels). At present, hydrogen is produced almost entirely from fossil fuels such as natural gas, naphtha, a...

Acknowledgements First of all, I would like to thank Lutz Kettner for supervising my thesis. In countless and fruitful discussions, he has delivered invaluable insight into the field of computational geometry and gave valuable feedback to my practical work, whenever it was required. Without him, this thesis would not have been possible in this form. Hachenberger for their self-sacrifying proof ...
