BACKGROUND Traffic is a source of environmental exposures, including benzene, which may be related to childhood leukemia. OBJECTIVES A national registry-based case-control study [ESCALE (Etude Sur les Cancers et les Leucémies de l'Enfant, Study on Environmental and Genetic Risk Factors of Childhood Cancers and Leukemia)] carried out in France was used to assess the effect of exposure to road ...
Electromigration is a major road block in the pursuit of further miniaturized electronics. In the next generation micro and sub micro electronics current density is expected to exceed 10 A/cm. In this paper an electromigration induced strain-current density model is proposed and implemented in finite element procedure for solution of boundary/initial value electromigration problems. Numerical s...
The aim of this study was to use spatial statistics and geographic information systems identify high-risk areas for highway accidents in Nakhon Pathom, Thailand. Secondary data from the Ministry Transport on locations road network between 2021-2022 analyzed using Equivalent Property Damage Only (EPDO), Spatial Autocorrelation, Kernel Density Estimation, hotspot analysis. focused a province Cent...
—We developed and evaluated multiple linear regression models to describe the associations between watershed land use and geomorphology and angling success (catch per unit effort [CPUE; fish/h]) for sport fishes in wadeable streams in Mississippi. The mean angler CPUE for all species combined, sunfishes Lepomis spp., and black bass Micropterus spp. was strongly and positively associated with th...
Road construction is expanding worldwide, exacerbating both direct mortality by road-kills and habitat fragmentation, especially for mobile vertebrates such as bats. Understanding how road density affects bat communities in mosaic landscapes of various compositions configurations therefore critical. We acoustically sampled 172 southern France to: (i) disentangle the relative interacting effects...

Abstract: There is a continuing determination by academics and road professionals alike to investigate the most appropriate methods for identifying road accident hotspots particularly in urban areas. Increasingly this research has involved the use of GIS and spatial analysis in order to define both visually and statistically what can be defined as a road accident hotspot. Traditional methods of...
