PURPOSE Wildland fires present many injury hazards to firefighters. We estimate injury rates and identify fire-related factors associated with injury. METHODS Data from the National Interagency Fire Center from 2003 to 2007 provided the number of injuries in which the firefighter could not return to his or her job assignment, person-days worked, and fire characteristics (year, region, season,...

In order to ascertain the fire resistance performance of recycled aggregate concrete (RAC) components with different concrete compressive strengths, four full-scaled concrete columns were designed and tested under high temperature. Two of the four specimens were constructed by normal concrete with compressive strength ratings of C20 and C30, respectively, while the others were made from recycle...

PERFORMANCE CHARACTERIZATION OF HIGH PERFORMANCE CONCRETES UNDER FIRE CONDITIONS By Wasim Khaliq (Advisor: Prof. Venkatesh Kodur) Monday, April 30, 2012, 1:00 pm CEE Conference Room (EB 3546D) In recent years, high performance concretes (HPC) are finding increasing applications in buildings and infrastructure due to numerous advantages, such as higher strength and durability, these HPC offer ov...

Biotic interactions are often important in the establishment and spread of invasive species. In particular, competition between introduced and native species can strongly influence the distribution and spread of exotic species and in some cases competition among introduced species can be important. The Caribbean crazy ant, Nylanderia fulva, was recently introduced to the Gulf Coast of Texas, an...

This study focuses on the development of multi-material solutions for fire-resistant structural materials transport and thermal insulation in construction field. Special attention was paid to combining recyclable bio-mass derived raw without interfering with an easy end-of-life separation, recycling reuse. Fire-resistant biomass resins were associated basalt Mineral Fibres (BDMF) form prepregs,...

polyurethane foams are extensively used in different applications such as furnitures and sandwich structures due to better mechanical properties, higher acoustic and damping behavior, higher resistance to hydrocarbon, and aging.with respect to flammability of polyurethane materials and safety precaution in living and working environments there is a vital need to study and investigate published ...

Fire is a potentially powerful tool for achieving desired conditions of forest ecosystems. From an ecological perspective, the use of fire requires affirmative answers to either of the following questions: (1) Does it increase ecosystem health and sustainability? and (2) Does it preserve or restore unique species or habitats? Health and sustainability can be measured and defined in terms of: (1...

Numerical modeling using computers is known to present several advantages compared to experimental testing. The high cost and the amount of time required to prepare and to perform a test were among the main problems on the table when the first tools for modeling structures in fire were developed. The discipline structures-in-fire modeling is still currently the subject of important research eff...
