Abstract Background Trends of increasing area burned in many regions worldwide are leading to more locations experiencing short-interval reburns (i.e., fires occurring two or times the same place within 1–3 decades). Field and satellite indices burn severity well tested forests a single recent fire, but reliability these is poorly understood. We how commonly used field index (the Composite Burn...
Methyl bromide was commonly used in fire extinguishers in aircraft engines and in submarines during the second world war. Now it is widely used as a fumigant insecticide in grain stores.' 2 Mortality after intoxication by methyl bromide vapour may be high,' and is often associated with convulsions, usually resistant to standard anticonvulsant chemotherapy.' s We wish to draw attention to the co...
natural fire inflicting irreparable damage to rangelands and forest areas is cause changes in landscape ecology. the purpose of this research is comparison of artificial neural network (ann) and line regression (lr) models to predict of forest and rangelands fires to this end, the data consist fire burned area and fire were used weather data over a period of 7 years (2006-2012(.the result indic...
background: fire and explosion hazards are extremely important in processing units. this study was performed to identify the risk centers, the potential damage caused by fire and explosion, and the days of production cessation in the processing company. materials and methods: the present qualitative case study was conducted using dow’s index in 2015. the fire and explosion hazard index and leve...
The use of fire-retardant/resistant coatings (FRC) is an effective and important method to delay the spread fire or protect intact structure against fire. Due high demand for FRC in end-user industries such as construction transportation, how efficiently determine identity has become a critical but difficult task protection investigation. This paper presents application laser-induced breakdown ...
In this study, nanooctahedra MnFe₂O₄ were successfully deposited on a wood surface via a low hydrothermal treatment by hydrogen bonding interactions. As-prepared MnFe₂O₄/wood composite (MW) had superior performance of soft magnetism, fire resistance and electromagnetic wave absorption. Among them, small hysteresis loops and low coercivity (<±5 Oe) were observed in the magnetization-field curve ...
