But these "controlled burns" are still fires——they can be hard to control and dangerous for the firefighters who start them. So some firefighters are now using drones to remotely drop Pine-Ponchball-sized "drone trees" over areas they want to burn. The trees include flammable(易燃的)...
But these "controlled burns" are still fires-theey can be hard and dangerous for the firefighters who start them. So some firefighters are now using drones drop Ping-pong-ball-size "dragon eggs" over areas they want to burn. The eggs include flammable material that burns upon landing on ...
Results from micro-charcoal and macro-charcoal data show similar trends in biomass burning and suggest that the major signal of both charcoal size-fragments relates mainly to local fires. Fire activity was low during the lateglacial, attained maximum values in the early Holocene (11,700鈥 8000 ...
Biofuels accounted 93% of total biomass consumption (577MTyr_1), with forest fires contributing only 7%. This is in contrary to global patterns, where forest fires are the primary and biofuels a negligible contributor. The biofuel-mixvaried across different regions, with a national average of ...
The Indian burning precludes large fires feeds into the “fuels is the problem” narrative which is increasingly discredited a major factor in large wildfires which are driven by extreme climate weather. All large fires are driven by climate/weather condition that include drought, low humidity, high...
In fighting gas- and oil- well fires so far only large quantities of water have been used to cool the very hot steel debris which would reignite the burnable materials, then using dynamite to blow out the flames In this invention the burning zone is usually first moved away from the well...
Light carboxylic acids in Greenland ice: A record of past forest fires and vegetation emissions from the boreal zone Measurements of light carboxylic acids (formate, HCOO; acetate, CH3COO; glycolate, C2H3O3; and oxalate, C2O4) were performed along Summit (central Greenlan... M Legrand,M...
Burning of tropical savanna grasslands is common practice in order to stimulate new regrowth for wildlife and livestock. To assess the effects of fire seasonality on the quality of post-fire regrowth as a food source for grazing herbivores, a burning experiment was set up in a moist savanna in...
More than 20 fires were burning in the Southeast Fire Centre as of Saturday afternoon As of Saturday afternoon, more than 20 fires were burning in the Southeast Fire Centre, with two of them — the Hobo Creek fire and the St. Mary Fire — designated as fires of note. ...
In Western Norway, farmers have traditionally used fire as a management tool in coastal heathlands to enhance the fodder quality for livestock. Rotational
