This study presents the combined analysis of RADARSAT products of different spatial resolutions acquired under different incidence angles for mapping burnt scars on forested areas of Central Portugal. Prior to the SAR data analysis, a number of pre-processing procedures were carried out. Noise was eliminated by adaptive texture preserving filtering. A specific algorithm for the geocoding of SAR...

cranial trephination is a technique which was used by ancient people to trephine skulls with some instruments. there are different types of trephination, the most common and primitive of which were trianglular and quadrangular in shape. a group burial was found in an archeological excavation of burnt city in sistan province in 1977. out of the 13 skeletons, one skeleton belonged to a 13th years...

effect of fire on phyto-sociology of understorey vegetation in chir pine forests of three different silvological characteristics was compared with pure grassland. 15 grasses, 1 sedge, 5 legumes and 21 non-legumes were recorded in the four study sites. floristic composition gradually increased from june to august and then declined slowly by october in all the plots. maximum number of species was...

The Cerrado is the second largest biome in Brazil after the Amazon and is the savanna with the highest biodiversity in the world. Serra Tombador Natural Reserve (STNR) is the largest private reserve located in Goiás State, and the fourth largest in the Cerrado biome. The present study aimed to map the burnt areas and to describe the spatial patterns of fire recurrence and its interactions with ...

The identification of severely burnt human remains by genetic fingerprinting is a common task in forensic routine work. In cases of extreme fire impact, only hard tissues (bones, teeth) may be left for DNA analysis. DNA extracted from burnt bone fragments may be highly degraded, making an amplification of genetic markers difficult or even impossible. Furthermore, heavily burnt bones are very pr...
