11. New regulators of xylem lignification in arabidopsis
Sammanfattning : The ability of land plants to grow upright, bear their own weight and withstand adverse environmental conditions is largely dependent on the secondary xylem tissues of the stem. The xylem cells acquire thick secondary cell walls which are composed of cellulose, hemicellulose and lignin. LÄS MER
12. Systems Analysis for Eco-Industrial Development : Applied on Cement and Biogas Production Systems
Sammanfattning : Our industrial systems are not sustainable—a major challenge which demands several types of responses. Eco-industrial development can be seen as such a response, with the goal to establish industrial systems that are both ecological and economical. Industrial Ecology is another closely related response. LÄS MER
13. Stability of statically and periodically loaded structures
Sammanfattning : In this thesis different kinds of stability phenomena are analysed. Firstly the quasi-static behaviour of an elastic structure is studied for increasing loading. LÄS MER
14. Landfill mining approach for resource recovery from glass dumps into the circular economy
Sammanfattning : Landfills and open dumps have been the most cost-effective waste disposal option, resulting in over 500,000 landfills and dumps in the EU alone. They pose significant environmental and health threats due to emission of toxic gases and release of persistent contaminants to soil and groundwater, triggering a considerable global economic impact annually.

15. Preference Effects in the Treatment of Panic Disorder
Sammanfattning : Patient preferences have drawn considerable attention as a potential moderator of treatment outcome. The Doubly Randomised Controlled Preference Trial (DRCPT) in which patients are randomised to a choice between two or more treatments or random assignment to one of these same treatments is considered one of the most rigorous tests of the effects of patient preferences on outcomes.
