Infrared sensors on board satellites have been widely used to collect statistics on fires, but not for fire control. Since the polar-orbiting satellites cover the northern Earth latitudes several times a day, their data are particularly suitable for detecting boreal forest fires. Currently, radiometers on board NOAA and ERS-2 satellites are used for operational fire management in Finland. Telef...
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...
Background and aimsAIDS as a re-emergent disease and Viral hepatitis (B and C) as one of thBackground and objective: Fire safety is an important problem in hospitals. Movement less, lack of awareness and special situation of residents are the reasons of this subject. In more countries such as Iran, fire protection regulations have compiled within the framework of national building codes. Curren...

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;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 stu...
Of phenomena which much damage and irreparable import to forests and natural resources is the fire that each year, more than 100 fires occur in Iran and thousands of hectares of trees and plants eliminates. Given that fire risk is high in most parts of the world, full and continuous monitoring on this natural phenomenon, is essential. Use remote sensing is a way to identify and manage fire. Ahe...
This study aimed to investigate the effects of the fire products treatments (heat, smoke and ash) on the density, species diversity, growth form and the life form of the soil seed bank in the semi-steppe rangelands of the Karsanak region in Chaharmahal and Bakhtiari Province. For this purpose, soil samples were collected from the studied region and fire products treatments were applied to them...
fire destroys major area of forests and rangelands in the world. izhe, located in khozestan province, is one of these area that was changed by this natural phenomena. the aim of this study is to determine the most important climatic factors on forest fire and its development by regression model analysis. numbers and area of the forest fire as well as weather data for a three years period (2009-...
