he epidemiological study of burned patients in west azarbalian (1382) m. khoshkalam [1] ,m.s. jamirzadeh [2] , m.s . abstract introduction: bum injuries still produce a significant morbidity and mortality in iran. this study was carried out to show the epidemiology, mortality, and etiological factors of burned patients in province of west azarbaijan. methods & materials: this stud...
[1] A synthesis was carried out to analyze information available to quantify fire activity and burned area across North America, including a comparison of different data sources and an assessment of how variations in burned area estimate impact carbon emissions from fires. Data sets maintained by fire management agencies provide the longest record of burned area information. Canada and Alaska h...
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...
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...
Accurate production of regional burned area maps are necessary to reduce uncertainty in emission estimates from African savannah fires. Numerous methods have been developed that map burned and unburned surfaces. These methods are typically applied to coarse spatial resolution (1 km) data to produce regional estimates of the area burned, while higher spatial resolution (,30 m) data are used to a...
A two stage burned scar detection approach is applied to produce a burned scar map for Mediterranean Europe using IRS-AWiFS imagery acquired at the end of the 2009 fire season. The first stage identified burned scar seeds based on a learning algorithm (Artificial Neural Network) coupled with a bootstrap aggregation process. The second stage implemented a region growing process to extend the are...
Background: Toxic shock syndrome (TSS), a dangerous consequence of Toxic shock syndrome toxin-1 (TSST-1) caused by Staphylococcus aureus. The early detection for infections of Staphylococcus aureus in burned children is very important, also the pre-vention for consequences of TSST-1. Fever is one of the most noticeable sign in burned children. On the other hand, fever is one of the important co...
