Combustion hazard of mixing ammonia with nitric oxide

Premixed ammonia/nitric oxide flame was simulated using the Lindstedt 1994 and Miller–Bowman 1989 reaction mechanisms in CHEMKIN. The predicted laminar burning velocities compared well with limited measured values in the literature. The effects of unburnt mixture temperature and pressure on laminar burning velocity, flammability limits, adiabatic flame temperature and species profiles were studied. The unburnt mixture temperature had a positive impact on both the laminar burning velocity and the adiabatic flame temperature, and it extended the ammonia-rich flammability limit. The pressure had a marginally negative influence on the laminar burning velocity, while it had a slightly positive effect on the adiabatic flame temperature.     

Free or low-cost geoinformatics for disaster management: Uses and availability issues

The disaster management applications of geographical information systems and remote sensing are examined relative to the disaster cycle, in pre-disaster, crisis and post-disaster contexts. We focus on the uses and limitations of free or low-cost data and software. A wide range of geospatial datasets are currently freely available, from digital elevation models (DEMs) and thematic digital maps, to multispectral satellite imagery and virtual globes, such as Bing Maps. Maps of hazardous terrain and vulnerable features can be derived from sets of satellite data such as shuttle radar topography mission DEMs and Landsat imagery. The derived maps are particularly useful for district scale (1:25 to 1:100 K) disaster management in low-income countries. Detailed maps (i.e. better than 1:25 K scale) of hazardous terrain and vulnerable features generally require expensive high-resolution satellite imagery or aerial photography.

Although the Internet allows the distribution of free or low-cost geospatial data, software and training materials, there are still some countries with limited Internet access. Data integration, spatial/temporal analysis and map production are also limited by the frequently high price of geoinformatic software, making it a priority to develop suitable Free and Open-Source Software.
