16. Frost-induced deterioration of concrete in hydraulic structures : Interactions between water absorption, leaching and frost action
Sammanfattning : Frost deterioration of concrete can result in severe consequences to the safety, durability and functionality of a structure since it impairs the strength of the concrete. Frost damage may occur to structures that are in contact with water and subjected to frost action. LÄS MER
17. Multidrug-Resistant Escherichia coli and Klebsiella pneumoniae : Treatment, Selection and International Spread
Sammanfattning : The prevalence of Escherichia coli and Klebsiella pneumoniae producing extended-spectrum beta-lactamases (ESBLs) and carbapenemases is increasing worldwide. Therapeutic options for infections with these bacteria are limited not only by the production of ESBLs and carbapenemases, which confer resistance to cephalosporins and carbapenems, but also by frequent co-resistance to other antibiotics.

18. Oxidation, Creep and Fatigue Synergies in Cast Materials for Exhaust Manifolds
Sammanfattning : The future development of engines of heavy-duty vehicles towards reduced CO2 emission will increase the exhaust gas temperature and render the exhaust atmosphere more corrosive. The current service material of exhaust gas components - a ferritic ductile cast iron called SiMo51 - will soon meet its upper-temperature limit. LÄS MER
19. District heating in future Europe : Modelling expansion potentials and mapping heat synergy regions
Sammanfattning : This thesis presents a set of methodologies and approaches to investigate and determine the extent by which district heating can contribute to improved energy system efficiency and reduced carbon dioxide emissions in future Europe. The main motivation for suggesting large-scale implementation of district heating as a structural energy efficiency measure to obtain these objectives originates essentially in the predicament that a majority of European buildings today remain highly dependent on fossil fuels to provide energy needed for space heating and hot water preparation.

20. Multidisciplinary Design in Aeronautics, Enhanced by Simulation-Experiment Synergy
Sammanfattning : This thesis covers some aspects of current aircraft design, and presents how experiment and simulation are used as tools. Together they give enhanced effects over employing either one separately. The work presented has been produced using both simulations and experiments. LÄS MER
