Modern flammable ecosystems include tropical and subtropical savannas, steppe grasslands, boreal forests, and temperate sclerophyll shrublands. Despite the apparent fiery nature of much contemporary vegetation, terrestrial fossil evidence would suggest we live in a time of low fire activity relative to the deep past. The inertinite content of coal, fossil charcoal, is strikingly low from the Eo...

moderate resolution imaging spectroradiometer (modis) have been widely used for active fire detection in the world as the specific channels used for the fire detection have made the modis images applicable. the main objective was to explore the capability of modis images for active fire detection in the zagross forests using the modis contextual algorithm. the study was performed in the marivan...

the risks of fire and explosion in oil and gas industry need to be managed. the objectives of the present study were to assess the risk of fire and explosion in iso-max unit of tehran oil refinery using dow’s fire and explosion index and to study the influences of the controlling methods. the latest version of dow fire and explosion index guideline was applied to calculate the fire and explosio...

fire behavior of different types of eps was evaluated with the use of iso 5660 cone calorimeter test method. considering the complexity of behavior of eps against high temperatures, several specimens were tested, so a betterjudgment on fire behavior of this material could be acquired. the effects of foam density, thickness of specimens and the level of heat flux on fire behavior of foam were ex...

aid uses, including fire stations, according to critical activities that are responsible, in comparison to other city services, are more important. identify areas where are located outside of the fire stations covered services can help urban planners to site selection of this important land use. the purpose of this paper is detection the areas that are beyond the services coverage of the fire s...

according to reports of forest range and watershed management organization of iran, hundreds of forest fires take place in our country every year. due to destroying forest and grass land in different parts of iran, especially in zagross and alborz mountain, it is necessary to develop new methods to reduce fire effects in these places. there are many parameters that increase probability of fire ...

fire is one of the most dangerous phenomena in the world which yields main damages, healthy and economical, and is thus a major threat to hospitals. since, most of the residents in hospitals are the individuals who cannot rescue themselves in such situations, fire in hospitals is more hazardous than any other public place; hence, it can endanger several sophisticated medical equipment. therefor...
