of OPERATIONAL FIRES ON THE URBAN BATTLEFIELD: AN UNDERDEVELOPED CONCEPT The US military will continue to be confronted in asymmetric warfare by adversaries who establish their power centers in urban terrain. Recent history has demonstrated that US forces can defeat adversaries on the conventional battlefield through overwhelming tactical and operational fires. Specifically, the employment of o...

Meteorological conditions, extremely conducive to fire development and spread in the spring of 1987, resulted in forest fires burning over extremely large areas in the boreal forest zone in northeastern China and the southeastern region of Siberia. The great China fire, one of the largest and most destructive forest fires in recent history, occurred during this period in the Heilongjiang Provin...

Accidental release scenarios such as flammable gas leaks or ruptures of pipes and pressurised process-equipment normally originate high velocity jets which, if ignited, give rise to jet fires. Although the direct effects of jet fires are considered to be relatively smaller than that associated to other types of fires, they are characterized by high heat fluxes and, especially if there is flame ...

[1] The new Global Wildland Fire Emission Model (GWEM) has been developed on the basis of data from the European Space Agency’s monthly Global Burnt Scar satellite product (GLOBSCAR) and results from the Lund-Potsdam-Jena Dynamic Global Vegetation Model (LPJ-DGVM). GWEM computes monthly emissions of more than 40 chemical compounds and aerosols from forest and savanna fires. This study focuses o...

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,...

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-...

When fires occur in the OR, they are devastating and potentially fatal to both patients and health care workers. Fires can be prevented by understanding the fire triangle and methods of reducing fire risk, conducting fire risk assessments, and knowing how to respond if a fire occurs. This Back to Basics article addresses the basics of fire prevention and the steps that can be taken to prevent f...

Coal fires have been found to be a serious problem worldwide in coal mining reserves. Coal fires burn valuable coal reserves and lead to severe environmental degradation of the region. Moreover, coal fires can result in massive surface displacements due to the reduction in volume of the burning coal and can cause thermal effects in the adjacent rock mass particularly cracks and fissures. The Wu...

There is increased interest in the use of summer-season fires to limit woody plant encroachment into grasslands, but effects of these fires on grasses are poorly understood. We quantified effects of repeated winter fires, repeated summer fires, and clipping (to simulate grazing) on aboveground total yield, live yield, and percentage of live tissue of C3 Texas wintergrass (Nassella leucotricha [...
