22. Structure Dependent Chemical and Biological Interactions of Poly(urethane urea)s
Sammanfattning : Poly(urethane urea)s, PUURs, are widely used in both industrial and biological applications because of excellent physical and mechanical properties and good biocompatibility in a variety of applications. Both the processing and the tailoring of specific properties of PUUR demand great knowledge of structure-property relationships. LÄS MER
23. NOx Abatement Technique for Marine Diesel Engines - Improved Marine SCR Systems
Sammanfattning : Growing awareness of the environmental implications of nitrogen oxide (NOX) emissions, such as eutrophication and acidification on land and at sea, has contributed to the development of more stringent international NOX legislations within the framework of the International Maritime Organization (IMO). The most stringent IMO legislation, i.e. LÄS MER
24. Bio-Inspired Urea Dosing and NOx Conversion : using a Biomimetic Effervescent Injector
Sammanfattning : Transport of people and freight on-road have a big impact on the total energy use in the world. The majority of these transports is propelled with diesel engines and the reason is simply that the diesel engine is better than the gasoline engine due to lower fuel consumption. But the cost of this is the increase in dangerous nitrogen oxides (NOx). LÄS MER
25. On microvascular blood flow assessment with the new microdialysis urea clearance technique
Sammanfattning : The aim of this thesis was to develop and evaluate a new way of monitoring blood flow with microdialysis. A thin catheter consisting of a semipermeable membrane is implanted in the tissue being studied. LÄS MER
