Impact of aging in fingerprint ridge density: Anthropometry and forensic implications in sex inference

The variation in the epidermal ridge's width between the sexes, during various growth stages, and among different populations has been previously assessed. However, the changes that occur with aging are barely known. The goal of this study was to analyse the degree of variation in epidermal ridge width due to aging. So that, fingerprint ridge density was estimated to establish their relationship with body and hand size changes that typically occur in adulthood. In this study, a sample of 213 adults of both sexes from a Spanish native population of different age ranges?18?30?years old (?junior? group) and 50?66?years old (?senior? group)?was used. Ridge density was assessed in three counting areas of the distal phalanx of each finger (radial, ulnar, and proximal). Height, weight, and a set of anthropometric measurements for both hands were also taken. Our results show that ridge density is higher in females than males throughout adulthood and decreases with aging in the radial and ulnar areas (as the hands widen) but not in the proximal region. Thus, a relationship between hand dimensions and ridge density was found. The data indicate that aging changes may conceal the recognized sex differences in ridge density, and so a better understanding of the topological variations in the epidermal ridge width throughout the life cycle and the factors involved would facilitate the interpretation of the differences between the sexes and different age groups

Application of biomass gasification fly ash for brick manufacturing

Biomass gasification technology offers an attractive way to use low-grade fuels in energy production with high efficiency and low environmental impact. However, an issue calling for further development is the volume and quality of fly ash, since biomass gasification fly ash contains more un-reacted carbon compounds than fly ash from direct combustion of similar fuels. This restricts direct gasification ash utilisation for many applications and makes some pre-treatment necessary, representing a significant share of the overall operating cost of gasification-based systems for energy production. Therefore, economical methods for the management of this type of ash without any pre-treatment are attractive. In this paper, we present an initial study on the manufacture of bricks made of gasification ash. Our goal was to come up with a product which satisfies two basic requirements: (a) it has elevated percentages of fly ash; and (b) it enables utilisation of ash without any pre-treatment. We have manufactured bricks by means of conventional moulding and curing methods, using ash percentages of up to 20 wt.%. No special additives were added to provide the bricks with acceptable mechanical and/or insulating properties. The fly ash used was generated in a fluidised bed pilot plant for processing olive mill cake, a by-product of the olive oil industry produced in large quantities in several EU countries. Some mechanical and environmental properties of ash gasification bricks were studied and compared with typical values for commercial bricks. The results lead us to conclude that the bricks could be used commercially as low density clay masonry units with a good thermal insulating capacity and, therefore, the potential for commercial development is promising. In addition, the environmental benefit of waste gasification added to the ash utilisation makes the overall process more attractive.Unión Europea NNE5-2001-0059
