In the present study, we use various spatial fuels data within a coupled atmospherewildfire model to compare the simulated fire behavior for a small portion of the16,000 acre Calabasas fire that occurred on 21-22 October 1996 in the Santa Monica Mountains of Los Angeles County (Bamattre et al., 1997). The fire simulation investigates an intense fire that occurred in an isolated canyon around no...
Assessing impacts of management strategies may allow designing more resistant forests to wildfires. Planning-oriented models to predict the effect of stand structure and forest composition on mortality for supporting fire-smart management decisions, and allowing its inclusion in forest management optimization systems were developed. Post-fire mortality was modeled as a function of measurable fo...
fire blight, caused by the bacterium erwinia amylovora, is one of the most destructive diseases of plants in the rosaceae subfamily pomoideae. the objective of this study was to determine the level of resistance of 30 pear cultivars and describe the biochemical changes induced in some resistant and susceptible cultivars. the level of resistance was determined by the length of the fire blight le...
Forest fire brings forest destruction as an important part of human environments, air pollution, and the loss of wealth and facilities, and endangers the lives of human beings in the vicinity of the forest. It is one of the examples of natural crises and is considered to be a crisis management. Identifying the effective factors in the occurrence of fire and hazard zoning is one of the basic too...
This study was conducted to investigate the effects of applying methods andamount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy andmechanical properties of wood flour/polypropylene composites. The resultsshowed that addition of fire retardant improved the mechanical properties such astensile and flexural strengths and fire retardancy of composites. But by increasingof fire retar...
