11. Water-in-diesel emulsion and microemulsion fuels -The effect of water on emission levels
Abstract : Water-in-diesel emulsions are known as environmentally favourable alternatives to conventional diesel fuel. Introducing water into the combustion results in reduced emissions of the health hazardous components nitrogen oxide (NOx) and particulate matter (PM). The concept of using emulsions is advantageous as it is easy to replace regular diesel. READ MORE

12. Photospheric emission from structured, relativistic jets : applications to gamma-ray burst spectra and polarization
Abstract : The radiative mechanism responsible for the prompt gamma-ray burst (GRB) emission remains elusive. For the last decade, optically thin synchrotron emission from shocks internal to the GRB jet appeared to be the most plausible explanation. READ MORE

13. Modeling of Radio Emission from Supernovae : Application to Type Ia
Abstract : The interaction of supernova (SN) ejecta with the circumstellar medium (CSM) drives a strong shock wave into the CSM. These shocks are ideal places where effective particle acceleration and magnetic field amplification can take place. READ MORE

14. Combustion Characteristics of a Swirl Dry Low Emission Burner Concept for Gas Turbine Application : Experiments and Simulations
Abstract : In the current global energy scenario, gas turbine can provide delicate balance between the booming worlds energy requirement and a pollutant free sustainable society. Cleaner combustion of fuel (particular natural gas), efficient, reliable, low maintenance and cost effective operation of gas turbine attracted scientific community to push the limit further (high efficiency and zero emission gas turbine).

15. Imaging fear and anxiety in the human brain : Positron emission tomographic studies
Abstract : Fear and anxiety are central human experiences. However, the relation between aspects of these aversive emotional states and brain function have previously been studied mostly in animals. READ MORE
