In this study, a naturally aspirated spark ignition engine fueled by low calorific gas (LCG) was tested in both exhaust gas recirculation (EGR) and lean burn modes, and the effects of these modes on engine performance and combustion and emission characteristics were evaluated and compared. The...

Span 80 and Tween 80 are biodegradable surfactants that can be added to blended fuels such as hydrated bioethanol-gasoline and methanol-gasoline. They increase the fuels' water tolerance and reduce their corrosive properties, without altering their fuel characteristics. For this study, a mixture...

The study adds an empirical outlook on the predicting power of using data from the future to predict future returns. The crux of the traditional Capital Asset Pricing Model (CAPM) methodology is using historical data in the calculation of the beta coefficient. This study instead uses a battery...
