1. Imaging of nucleocytoplasmic transcription factor dynamics in yeast
Abstract : Fluorescence microscopy has proven to be an invaluable tool in identifying and understanding cell signalling, intracellular spatial and temporal dynamics, and cell-to-cell variability. This thesis focuses on imaging of nucleocytoplasmic transcription factor dynamics at the single cell level in yeast. READ MORE

2. Fatigue Assessment of Container Ships – a Contribution to Direct Calculation Procedures
Abstract : Within the field of marine structural engineering, the introduction of new materials and material classes, the development of production techniques and new design, and new requirements imposed by authorities are examples which justify a need for continuous revisit and update of fatigue assessment methodologies of marine structures. This thesis contributes to the development and improvement of fatigue assessment methodology for ship structures. READ MORE

3. Fatigue life extension in existing steel bridges. High-Frequency Mechanical Impact treatment and Tungsten Inert Gas remelting in life extension and fatigue crack repair of welded steel structures
Abstract : This thesis investigates the performance of improved welds with two post-weld treatment methods for application on existing structures. High-Frequency Mechanical Impact (HFMI) treatment and Tungsten Inert Gas (TIG) remelting were used for fatigue life extension of welded structures. READ MORE

4. Abiotic Stress Tolerance. Metabolic and Physiological Effects of Compatible Solutes and Calmodulin on E. coli and Tobacco
Abstract : In their natural habitats, bacteria and plants can be exposed to abiotic stresses such as drought, high salt concentrations and freezing, which are factors limiting their capacity for growth and proliferation. To withstand environmental stresses, they have evolved specific stress responses. READ MORE

5. Functional studies of Escherichia coli stringent response factor RelA
Abstract : RelA is a ribosome associated multi-domain enzyme, which plays a crucial role in adaptation ofEscherichia coli to nutritional stress as such as amino acid deficiency. It detects the deficiency of aminoacids in the cell by monitoring whether a tRNA at the acceptor site (A-site) of the ribosome is chargedwith amino acid or not. READ MORE
