Small-scale pilot projects have demonstrated that integrated population, health and environment approaches can address the needs and rights of vulnerable communities. However, these and other types of health and development projects have rarely gone on to influence larger policy and programme development. ExpandNet, a network of health professionals working on scaling up, argues this is because...

The present work investigates the effect of pilot fuel properties on TF combustion using premixed methane-hydrogen-air (CH4-H2-air) mixtures ignited by a small amount diesel pilot. Especially, we are investigating cetane number (CN) and aromatic content (AC) in single-cylinder compression ignition (CI) engine at varying charge air temperatures (Tair = 25 °C, 40 55 °C) H2 volume fractions (MH2 1...

The U.S. Environmental Protection Agency initiated a pilot program in 2002 with researchers at the University of Michigan Air Quality Laboratory to investigate motor vehicle mercury emissions. The program included exhaust emissions characterization of vapor and particulate phase mercury from three light-duty gasoline vehicles, one diesel vehicle and mercury analysis of fuel, lubricating oil, en...

Dumps of a mining-metallurgical complex of post-Soviet Republics have accumulated a huge amount of technogenic waste products. Out of them, Kazakhstan alone has preserved about 20 billion tons. In the field of technogenic waste treatment, there is still no technical solution that leads it to be a profitable process. Recent global trends prompted scientists to focus on developing energy-saving a...

Tar formation is the main bottleneck for biomass gasification technology. A novel rotary kiln type biomass gasification process was proposed. The concept design was based on air staging and process separation. This concept was demonstrated on a pilot scale rotary kiln reactor under ambient pressure and autothermic conditions. The pilot scale gasifier was divided into three different reaction re...

In diesel engines, it is difficult to reduce both smoke and NOx simultaneously. An experimental study was conducted to determine the performance and exhaust emission characteristics of a commercial single cylinder, natural aspirated, air cooled DI diesel engine. The system was modified to work on either dual fuel or diesel alone. The objective of this work is to investigate the possibility of d...
