1. On Gas Contaminants, and Bipolar Plates in Proton Exchange Membrane Fuel Cells
Abstract : The proton exchange membrane (PEM) fuel cell is an electrochemical device that converts chemical energy into electrical energy through two electrocatalytic reactions. The most common catalyst used is platinum on carbon (Pt/C), which has shown the best performance in the fuel cell until now. READ MORE

2. Adaptive Finite Element Procedures in Structural Dynamics
Abstract : This thesis deals with a posteriori error estimation and adaptivity in finite element procedures for the analysis of structural dynamic problems. First, error estimation and adaptivity for the Newmark time integration method are studied. READ MORE

3. Biogas Production from Lignocellulosic Biomass : Impact of pre-treatment, co-digestion, harvest time and inoculation
Abstract : Biogas or methane production through anaerobic digestion (AD) is gaining increasing attention worldwide due to concerns over global warming, energy security and the need for sustainable waste management. AD of lignocellulosic biomass is one facet that is highly appreciated since the conflict over biomass for food/feed or energy can be avoided. READ MORE

4. Polycyclic aromatic compounds (PAC) in diesel fuels and exhaust emissions : aspects of sampling techniques, chemical determination, multivariate data interpretation and PAC emissions reduction
Abstract : The rapid growth in the number of motor vehicles has raised serious environmental health hazard problems in urban areas associated with vehicle exhaust emissions. Exhaust emissions from heavy duty diesel vehicles are very complex mixtures containing thousands of chemical components distributed between the particulate, semivolatile and gaseous phases. READ MORE

5. Glial cell responses, complement and clusterin expression after lesions in central or peripheral nervous system
Abstract : The present Thesis examines the expression and role of complement and the complement regulator clusterin after central or peripheral axon injury in relation to the responses of non-neuronal cells. Following peripheral sensory nerve injury, complement was expressed in the spinal cord and brain stem in association with reactive microglia, which also appeared to be a local source of complement.
