Emissions of CO2 from road vehicles were 1.57 billion metric tons in 2012, accounting for 28% of US fossil fuel CO2 emissions, but the spatial distributions of these emissions are highly uncertain. We develop a new emissions inventory, the Database of Road Transportation Emissions (DARTE), which estimates CO2 emitted by US road transport at a resolution of 1 km annually for 1980-2012. DARTE rev...

OBJECTIVES Motor vehicle-pedestrian crash is a significant public health concern. The urban campus of Georgia State University poses unique challenges due to a large number of students and university employees. The objectives of this study are twofold: 1) to examine the correlation between specific features of the built environment on and around the University campus and pedestrian crashes; and...

A system that can acquire and share information about the environment from vehicles using various sensors smartphones was developed to prevent accidents may occur on mine haulage roads. light detection ranging sensor an accelerometer in a smartphone were used determine road surface conditions at mining site, dust gas measure atmospheric environment. The GPS function of utilized obtain location ...

Middle Jurassic (Bajocian-Bathonian) Sphenophyta fossils of the silicified level peats of the Pabdana Coal Mine (Kerman) recovered. Four new species of Sphenophyta described for the first time. They include Equisetites pabdanaii sp. nov., Equisetites sparseii sp. nov., Equisetites hojedkii sp. nov. and Equisetites irregularii sp. nov.,. Descriptions of the above mentioned new species has been d...

Silicosis, a debilitating and potentially deadly lung disease, develops through inhalation of excessive concentrations of respirable crystalline silica dust. In underground coal mines, continuous miner operators have a high risk of overexposure to silica, with approximately 25% of compliance dust samples exceeding the permissible exposure limit. Continuous miners often extract high-silica-conte...

To investigate potential health risks associated with exposure to metals from an abandoned metal mine, the authors studied people living near an abandoned mine (n=102) and control groups (n=149). Levels of cadmium, copper, arsenic, lead, and zinc were measured in the air, soil, drinking water, and agricultural products. To assess individual exposure, biomarkers of each metal in blood and urine ...

background: driver fatigue is one of the major implications in transportation safety and accounted for up to 40% of road accidents. this study aimed to analyze the eeg alpha power changes in partially sleep-deprived drivers while performing a simulated driving task. methods: twelve healthy male car drivers participated in an overnight study. continuous eeg and eog records were taken during driv...

For early-successional species, road and powerline cuts through forests provide refugia and source populations for invading adjacent forest gaps. Within an 800 km’ forest matrix in South Carolina, we determined if width. disturbance frequency or linear features of road and powerline cuts influenced the mound distribution of the red imported tire ant, Solenopsis invicta Buren. For each of live l...
