Fire is one of the incorporate vegetation management practices for grasslands and semi-arid rangelands. It may affect symbiotic relationship between range plants and mycorrhiza. Accordingly, this research was aimed to investigate the effects of a spring prescribed fire on the symbiotic relationships between mycorrhiza and 6 plant species. The study was conducted in a semi-arid steppe rangeland ...
Background & Objectives : It is not possible to live without using fire. However, fire could destruct human properties in a short time. One of the most important types of fire is intentional fire. This type of fire has become a great problem for insurance companies, fire departments, industries, government and business in the recent years. This study aimed to provide a framework for risk assess...
Wildfires are of the forest-related disasters caused by inhumane factors. Spreading of these fires is due to the increase of the density of flammable plants. Two important approaches to prevent this occurrence are fuel treatment and fire suppression resources preparedness. In this paper, a mixed integer programming model is proposed based on the covering location and assignment problems which ...
Background and aims:Today one of the most important issues in organizations, companies, offices and schools is that people should know how to turn off the fires in emergency situation. Certainly knowing about fire factors and safety in workplaces can reduce the costs of fire accidents, and in this study our goal is to determine the knowledge level of students related to methods of fire control....
Background;Despite advances in technology, people are still exposed to fire hazard. Students can be one of the most important exposed groups. Therefore, fire safety inspection should be established in dormitories. The aim of this study was to develop a fire safety checklist for fire safety inspection in dormitories. Methods; This study was as a tool development followed by a cross-sectional st...
Beam-to-column connections have been found to be of great significance in influencing structural behavior at ambient and elevated temperatures. Observations from full-scale fire tests and damaged structures confirm that connections have a considerable effect on the stability time of structural components in fire. Due to the high cost of elevated temperature tests, adequate experimental data abo...
Fire is a valuable tool for maintaining biodiversity in many ecosystems throughout the world, particularly tropical savannas. An understanding of the impact of different fire management regimes is essential if desired outcomes are to be achieved. Numerous studies have shown patchy and inconsistent responses of insects to fire. This may be because detection of responses to fire was contingent up...
Fire and explosion analysis of filling station based on fuzzy mathematics and Bayesian network model
In order to explore the basic events and risk occurrence probability of fire explosion accidents in CNG (Compressed Natural Gas) filling station, a corresponding Bayesian network model was established based on fault tree station. The prior modified by introducing fuzzy mathematics process transforming into network, posterior station analyzed calculated GeNIe software. Finally, through case anal...
