1. Reliability-based design of rock tunnel support
Abstract : Since 2009, design of rock tunnels can be performed in accordance with the Eurocodes, which allows that different design methodologies are applied, such as design by calculation or design using the observational method. To account for uncertainties in design, the Eurocode states that design by calculation should primarily be performed using the partial factor method or reliability-based methods. READ MORE

2. Well Testing, Methods and Applicability
Abstract : Well testing is widely used today in water wells, oil and gas wells, for geothermal applications, within civil engineering projects, thermal storage and CO2 storage. The overall testing goal is to verify the productivity from a well and/or for characterization of hydraulic and thermal properties, as well as the spatial limitations of an aquifer. READ MORE

3. Drip Sealing Grouting of Tunnels in Crystalline Rock: Conceptualisation and Technical Strategies
Abstract : A conceptual model of the groundwater hydraulic conditions around the tunnel contour in ancient brittle crystalline rocks has been developed and verified. The general aim has been to reach an understanding of the groundwater conditions in and close to the tunnel roof where dripping takes place and to propose technical and practical strategies for waterproofing.

4. Biochemical Studies on a Plant Epoxide Hydrolase : Discovery of a Proton Entry and Exit Pathway and the Use of In vitro Evolution to Shift Enantioselectivity
Abstract : The work leading to this thesis has provided additional information and novel knowledge concerning structure-function relationship in the potato epoxide hydrolase. Epoxide hydrolases are enzymes catalyzing the hydrolysis of epoxides to yield the corresponding vicinal diols. READ MORE

5. On Catalytic Mechanisms for Rational Enzyme Design Strategies
Abstract : Enzymes enable life by promoting chemical reactions that govern the metabolism of all living organisms. As green catalysts, they have been extensively used in industry. However, to reach their full potential, engineering is often required, which can benefit from a detailed understanding of the underlying reaction mechanism. READ MORE
