1. Tracing marine hypoxic conditions during warm periods using a microanalytical approach
Abstract : Deoxygenation, i.e. loss of oxygen from the oceans, often considerably influences the aquatic organisms and the wholeecosystem and changes biogeochemical cycles. It results in increasing bottom areas of hypoxia (. READ MORE

2. When bioelectrochemical systems meet extremophiles, possibilities and challenges
Abstract : Extremophiles are microorganisms live and thrive in extreme environments that are harsh and hostile to most forms of life on earth (e.g. low pH, low temperature, high pH and high salinity). They have developed strategies to obtain nutrients and conserve energy to sustain life under these adverse conditions. READ MORE

4. Nonlinearly Perturbed Renewal Equations : asymptotic Results and Applications
Abstract : In this thesis we investigate a model of nonlinearly perturbed continuous-time renewal equation. Some characteristics of the renewal equation are assumed to have non-polynomial perturbations, more specifically they can be expanded with respect to a non-polynomial asymptotic scale. READ MORE

5. Numerical Study on Steel Flow and Inclusion Behavior during a Ladle Teeming Process
Abstract : Inclusions in molten steel have received worldwide concern due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the deoxidation process, reoxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE
