1. The ribosome, stringent factor and the bacterial stringent response
Abstract : The stringent response plays a significant role in the survival of bacteria during different environmental conditions. It is activated by the binding of stringent factor (SF) to stalled ribosomes that have an unacylated tRNA in the ribosomal A-site which leads to the synthesis of (p)ppGpp. READ MORE

2. 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

3. Assessment of Experimental, Computational, and Combined EFD/CFD Methods for Ship Performance Prediction
Abstract : In today’s highly competitive market, alongside increasingly stringent regulatory requirements, the precise prediction of ship performance has assumed paramount importance for both design verification and operational evaluations. This thesis addresses the need for a comprehensive assessment of Experimental Fluid Dynamics (EFD), Computational Fluid Dynamics (CFD), and their combination to enhance the accuracy of performance predictions.

4. Studies on Redox-proteins and Cytokines in inflammation and Cancer
Abstract : The redox state in the cell plays a major role in determining vital functions and its major imbalance can lead to severe cell injury or death. Redox active proteins and cytokines involved in this process includes thioredoxin (Trx), protein disulfide isomerase (PDI), and tumor necrosis factor (TNF) superfamilies. READ MORE

5. Hematopoietic stem cells: c-mpl and TNF receptor function
Abstract : Hematopoietic stem cells (HSC) are crucial to life. Daily and throughout the life span of an individual they are responsible for replacing approximately 10(12) mature blood cells. Mature cells are, for example, required for transportation of oxygen, defense against infections and to stop bleeding. READ MORE
