6. The effects of long chain alcohol blends on engine performance and spray characteristics in CI engines
Abstract : Replacing fossil fuels with alternatives derived from renewable sources is one way of meeting society’s increasing need for mobility while also significantly reducing greenhouse gas emissions from vehicles with internal combustion engines. To facilitate such a replacement, this thesis presents optical spray studies and engine experiments conducted to evaluate the potential of blends of biomass-derived alcohols and vegetable oils to serve as drop-in fuels for compression ignition engines.

7. Experimental Studies on Using Butanol and Octanol Isomers as Drop-in Fuels for Diesel Engines
Abstract : The increasing importance of transportation in modern societies has caused fossil fuel consumption to increase greatly in recent decades. However, burning fossil fuels in internal combustion engines can lead to high emissions of greenhouse gases, which cause climate change. READ MORE

8. Mixture Effects in Shell-and-Tube Condensers. Theory and Calculations
Abstract : Zeotropic mixtures have come into more frequent use as working fluids (refrigerants) in heat pumps and air conditioning equipment due to the phase-out of ozone-depleting substances. Substantial drop in performance for shell-side condensation in shell-and-tube condensers when replacing a pure fluid with a mixture has been reported in the literature. READ MORE

9. Catalytic Converters for Automotive Exhaust Applications. Flow Dynamics, Mass Transfer and Optimization
Abstract : In order to reduce emissions from vehicles powered by an internal combustion engine, an exhaust aftertreatment system is normally mounted on the engine. This aftertreatment system normally consists of one or several catalytic converters. READ MORE

10. Alterations in receptor expression and function in scrapie-infected neuronal cell lines
Abstract : This study shows that lipopolysaccharide (LPS) induces a robust, concentration-and time-dependent increase in nitric oxide (NO) production in the murine neuroblastoma cell line N2a by increased expression of iNOS. However, in scrapie-infected N2a cells (ScN2a), the LPS-induced NO production was completely abolished. READ MORE
