1. Hydropower Area Equivalents : Reduced Models for Efficient Simulation of Large-Scale Hydropower Systems
Sammanfattning : With over 4000 TWh yearly electricity production worldwide, hydropower plays an important role in many power systems. Unlike many other renewable energy sources, hydropower has a certain degree of controllability and high levels of flexibility over several time scales. LÄS MER
2. Large Area Propellers
Sammanfattning : Even if shipping is the most energy efficient and inexpensive way of transporting large volumes of goods across the world, it still could be significantly improved with respect to energy efficiency.In this thesis, propulsive efficiency is improved by moving the propeller backwards from its original position and increasing its diameter.

3. Methods and techniques for precise and accurate in-duct aero-acoustic measurements : Application to the area expansion
Sammanfattning : During the design and commissioning of combustion equipment, combustion associated instabilities are commonly encountered. These thermo-acoustic instabilities can cause undesirable noise, vibrations, local thermal and mechanical stresses in the combustor and are prominent in lean combustion. LÄS MER
4. Bacterial antibody hydrolyzing enzymes – as bacterial virulence factors and biotechnological tools
Sammanfattning : Antibodies are an essential part of the human immune system, and antibody mediated immunity has been an area of interest for many researchers for almost a century. An accumulation of knowledge regarding antibody structure, glycosylation and receptor interactions has contributed to the current understanding of antibody mediated immunity. LÄS MER
5. Human milk as a source of tumor killing molecules. From MAL to HAMLET
Sammanfattning : HAMLET (Human alphalactalbumin made lethal to tumor cells), a complex between the partially unfolded alphalactalbumin and oleic acid, was discovered by serendipity when anti-adhesive properties of human milk were examined. HAMLET kills tumor cells but not healthy differentiated cells. LÄS MER
