11. Generation of synthesis gas for fuels and chemicals production
Sammanfattning : Many scientists believe that the oil production will peak in the near future, if the peak has not already occurred. Peak oil theories and uncertain future oil deliveries have stimulated interest in alternative sources of fuel and chemicals. LÄS MER
12. Geometric Control of Thrust Propelled Systems
Sammanfattning : This thesis was motivated and inspired by the AEROWORKS project, a European research project, whose main goal was to deploy multiple heterogeneous unmanned aerial vehicles in environments where human intervention is restricted.In particular, this thesis focuses on control of aerial vehicles for the purposes of cargo transportation, an application of interest, for example, in inspection and maintenance of aging infrastructures.

13. Promises and Pitfalls of Bioenergy with Carbon Capture and Storage : Actors' Perspectives, Challenges, and Mitigation Deterrence in Sweden
Sammanfattning : Carbon dioxide removal (CDR) methods, such as bioenergy with carbon capture and storage (BECCS), have gained traction in international climate policy arenas to meet net-zero goals. Even though companies operating facilities with large point sources of biogenic emissions, such as pulp and paper industries and energy utilities, could implement carbon capture, there are few studies that take a bottomup perspective to study these key actors.

14. Function of contractile and cytoskeletal proteins in smooth muscle: Effects of hypertrophy and age and desmin removal in a transgenic animal
Sammanfattning : In man, the urinary bladder responds to an urinary outflow obstruction with a pronounced dilatation and growth of the bladder wall. This clinical situation can be mimicked in rat by creation of a partial urinary outflow obstruction and the papers included in the present thesis use this animal model to address questions regarding the adaptive changes in the smooth muscle of the growing bladder.

15. Water purification using polyelectrolyte modified cellulose fibers and filters to adsorb bacteria
Sammanfattning : Clean water is necessary for human survival and there is a need for development of cheap and easy water purification techniques to use in emergency situations when there is no access to safe drinking water. Bacteria contaminated water can cause lethal diarrheal diseases and is globally the second most common cause of death among children less than five years of age. LÄS MER
