BACKGROUND About half of the world's population is exposed to smoke from burning biomass fuels at home. The high airborne particulate levels in these homes and the health burden of exposure to this smoke are well described. Burning unprocessed biological material such as wood and dried animal dung may also produce high indoor endotoxin concentrations. OBJECTIVE In this study we measured airbo...

Fire is a dominant ecological factor in Mediterranean-type ecosystems. Management strategies include prescribed (controlled) burning, which has been used in the management of several species, such as Pinus nigra ssp laricio var. Corsicana, a pine endemic to Corsica of great ecological and economic importance. The effects of prescribed burning on Pinus laricio have been little studied. The first...

We report experiments and detailed numerical modeling of mixtures of primary reference fuel (PRF) droplets consisting of n -heptane and iso -octane with initial droplet diameters of 0.5 and 3.51 mm. The results show a quasi-steady, low temperature (or “Cool Flame” ( CF )) droplet burning mode that stems from a varying two-stage chemical kinetic behavior of the combustion chemistry. The simulati...
