The ecological impacts of wildland fire-suppression activities can be significant and may surpass the impacts of the fire itself. A recent paradigm shift from fire control to fire management has resulted in increased attention to minimizing the negative effects of suppression. While the philosophy behind minimumimpact suppression tactics has provided a good first step in this direction, increas...

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...

p 1 Host specificity of the decapitating fly Pseudacteon curvatus was studied to determine whether this species is suitable for release as a classical biocontrol agent of imported fire ants in the United States. A series of no-choice tests with 19 species of ants from 12 genera showed that P. curvatus will not develop in ants outside the genus Solenopsis. P. curvatus successfully parasitized th...

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...

We evaluated the abundance of nonnative plants on fuel breaks and in adjacent untreated areas to determine if fuel treatments promote the invasion of nonnative plant species. Understanding the relationship between fuel treatments and nonnative plants is becoming increasingly important as federal and state agencies are currently implementing large fuel treatment programs throughout the United St...

The worldwide movement toward performance-based building codes is prompting the need for new computational methods to predict fire endurance of wood assemblies. Progress in the past twenty years in understanding fire endurance of individual solid wood components has been achieved in many different countries. The greatest opportunity for major advance in fire research is the development of compu...

Gypsum board is a common fire barrier used in house and general building construction. Recently, evaluation of the collapses of the World Trade Center Towers highlighted the potential role and failure of gypsum board in containing the fires and resisting damage. The use of gypsum board as primary fire protection of light-flame wood or steel construction is ubiquitous. Yet knowledge of the commo...

This review considers the development of some of the models and modelling approaches designed to predict the spread and spatial behaviour of wildland fire events. Such events and their accurate prediction are of great importance to those seeking to understand and manage fire-prone ecosystems. The key problem which fire modelling seeks to address is outlined. Models predicting the rate of fire s...

The article is devoted to the consideration of one modern technologies for construction buildings and structures using SIP panels. features fire safety erected panels are analyzed. result study assumption possibility made social infrastructure facilities, especially in conditions limited availability, hazard being compared other traditional materials estimated
