Book Description
Pentecostalism came to the South following the post–Civil War holiness revival, a northern-born crusade that emphasized sinlessness and religious empowerment. With the growth of southern Pentecostal denominations and the rise of new, affluent congregants, the movement slipped cautiously into the evangelical mainstream.

Book Description
This manual documents procedures for estimating the rate of forward spread, intensity, flame length, and size of fires burning in forests and rangelands. Contains instructions for obtaining fuel and weather data, calculating fire behavior, and interpreting the results for application to actual fire problems.

Book Description
Wildland fires have an irreplaceable role in sustaining many of our forests, shrublands and grasslands. They can be used as controlled burns or occur as free-burning wildfires, and can sometimes be dangerous and destructive to fauna, human communities and natural resources. Through scientific understanding of their behaviour, we can develop the tools to reliably use and manage fires across landscapes in ways that are compatible with the constraints of modern society while benefiting the ecosystems. The science of wildland fire is incomplete, however. Even the simplest fire behaviours – how fast they spread, how long they burn and how large they get – arise from a dynamical system of physical processes interacting in unexplored ways with heterogeneous biological, ecological and meteorological factors across many scales of time and space. The physics of heat transfer, combustion and ignition, for example, operate in all fires at millimetre and millisecond scales but wildfires can become conflagrations that burn for months and exceed millions of hectares. Wildland Fire Behaviour: Dynamics, Principles and Processes examines what is known and unknown about wildfire behaviours. The authors introduce fire as a dynamical system along with traditional steady-state concepts. They then break down the system into its primary physical components, describe how they depend upon environmental factors, and explore system dynamics by constructing and exercising a nonlinear model. The limits of modelling and knowledge are discussed throughout but emphasised by review of large fire behaviours. Advancing knowledge of fire behaviours will require a multidisciplinary approach and rely on quality measurements from experimental research, as covered in the final chapters.

Book Description
Grassfirespresents the latest information from CSIRO on the behavior and spread of fires in grasslands. This second edition follows ten years of research aimed at improving the understanding of fundamental processes involved in the behavior of bushfires and grassfires. The book has been extensively revised and new case studies have been added to reflect the latest findings in research and investigations. The book covers all aspects of fire behavior and spread in the major types of grasses in Australia. It examines the factors that affect fire behavior in continuous grassy fuels; fire in spinifex fuels; the effect of weather and topography on fire spread; wildfire suppression strategies; and how to reconstruct grassfire spread after the fact. The three fire-spread meters designed by CSIRO and used for the prediction of fire danger and rate of spread of grassfires are explained and their use and limitations discussed. This new edition expands on the historical view of grassfires with respect to extensive Aboriginal burning, combustion chemistry, flame structure and temperature, spotting and spread in discontinuous/eaten out fuels, and the effect of wind in complex terrain. The case studies in the chapter "Wildfires and Their Suppression" have been updated and include the major wild grassfire events of recent years, the January 2003 ACT fires and the 2005 Wangary, SA fire. The "Myths, Facts and Fallacies" chapter includes new myths and a new section on personal safety during a wild grass fire. Of interest to all rural fire fighters and rural landholders, students and teachers of courses on landscape and ecological processes, rural and peri-urban dwellers, fire authorities and researchers.

Book Description
Fuel beds of ponderosa pine needles and white pine needles were burned under controlled environmental conditions to determine the effects of fuel moisture and windspeed upon the rate of fire spread. Empirical formulas are presented to show the effect of these parameters. A discussion of rate of spread and some simple experiments show how fuel may be preheated before the fire reaches the fuel. The interrelationship between unit energy release rate and rate of spread produces a fire characteristics curve. Diffusion flame analysis shows good agreement when working with 1/2-inch stick fires.

Book Description
To facilitate field use of the rate of fire spread equation used in Arizona oak chaparral, step-by-step instructions are presented in workbook form. Input data can be either measured or estimated from the tables and figures included; a sample computation form may be duplicated for field use. Solving the equation gives the land manager the guidelines for planning fire control efforts, or for using prescribed fire in the brush type.
