1. Studies addressing the immediate impacts of fire on forest arthropod communities and their implications for conservation are few, particularly for species within dead wood. To investigate the effects of fire on saproxylic beetles (Coleoptera), we randomly assigned large-diameter loblolly pine (Pinus taeda L.) logs to a forest scheduled for a prescribed burn (i.e. a low-intensity surface fire...

The predominant technique for tracking wildfires uses repeat satellite observations to look for and measure the size of burn scars, the charred remains of once-lush terrain. Because it relies on moderateresolution imagery, this approach has a tendency to miss the smaller fires that, though less widely devastating, can still account for a sizeable portion of the total burned area. Small fires ca...

The ability of Candida albicans to infect thermally injured mice was studied. Female mice were either left unburned or given a 20% total body surface area 2-s or 7-s scald burn. The wound or skin surface was then inoculated with a human burn wound isolate of C. albicans. At 4 h postburn, approximately 10(2) to 10(3) CFU/g of tissue could be recovered from the skin of burned and unburned animals...

Burns due to explosions of various types of inflammable dust have been reported, including coal dust, flour and grain dust. A 33-year-old worker was burned over 33 per cent of his body surface area in a sawdust explosion. Recovery was uneventful. This is the first reported case due to this mechanism as far as we have been able to ascertain.

Land surface albedo, a key parameter to derive Earth’s surface energy balance, is used in the parameterization of numerical weather prediction, climate monitoring and climate change impact assessments. Changes in albedo due to fire have not been fully investigated on a continental and global scale. The main goal of this study, therefore, is to quantify the changes in instantaneous shortwave alb...

An algorithm for burned area mapping in Africa based on classification trees was developed using SPOT-VEGETATION imagery. The derived 1 km spatial resolution maps were compared with 30 m resolution maps obtained with 13 Landsat scenes, through linear regression analysis. The procedure quantifies the bias in burned area estimation present in the low resolution burned area maps. Good corresponden...

Background and Goal: Burn is an irreparable event, which results in numerous physical, psychological, social, and economic complications. The burned patients should be merely treated in a professional burn center due to vast clinical range of these patients. Since, a percentage of mortality in burned patients is for the patients’ transportation from other centers; this study has aimed to invest...

The results of an experimental study of the combustion of single aluminum particles in N2/O2, Ar/O2, and He/O2 gas mixtures, and in pure O2 are presented and interpreted. This research focuses on identifying conditions under which asymmetric combustion of the aluminum particles develops. It also illustrates the relationship between aluminum particle combustion behavior and particle internal and...

Woody plants can cause localized increases in resources (i.e., resource islands) that can persist after fire. We tested the hypothesis that burned sagebrush subcanopies would have increased seedling establishment and performance of post-fire seeded perennial bunchgrasses compared to burned interspaces. We utilized five study sites in southeastern Oregon. The area was burned in a wildfire (2007)...

Woody plants can cause localized increases in resources (i.e., resource islands) that can persist after fire and create a heterogeneous environment for restoration. Others have found that subcanopies have increased soil organic matter, nitrogen, and carbon and elevated post-fire soil temperature. We tested the hypothesis that burned sagebrush subcanopies would have increased seedling establishm...
