Road safety index is an important indicator that has been recently introduced as a useful tool to measure the quality of life in many countries and cities. Road safety index is a complex index and it has at least three main components, including road user behavior, vehicle safety, and road infrastructure effects. Many researchers have selected studying road performance from road safety index pe...

road traffic injuries are known as the most prevalent childhood injury and besides being the greatest cause of child mortality, place an extraordinary burden on health care system. children’s limitation in cognitive, physical and social development makes them more vulnerable in road traffic injuries than adults. their small structure cause challenges to see and be seen and their risk taking beh...

I review what is known about the temperature of the plasma within stellar wind bubbles and superbubbles. Classical theory suggests that it should be hot, with characteristic temperatures of order a million degrees. This temperature should be set by the balance between heating by the internal termination shocks of the central stellar winds and supernovae, which expand at thousands of km s, and c...

INTRODUCTION Different factors related to winter are known to influence the fracture incidence, but little is known about the effect of road surface temperature. This study examines the association between road surface temperature and the daily number of fractures in an urban area during two winters. MATERIAL AND METHODS Retrospective data collection was conducted on all patients treated at B...

Every 6 seconds someone is killed or seriously injured on the world's roads. With 1.3 million road deaths each year this is a global epidemic comparable to malaria or Tuberculosis. Nine in ten road deaths and injuries are in developing countries. By comparison to other global killers, road injury is neglected. Road crashes are the leading global cause of death for young people under 25 years, a...

We have investigated how edge effects influence the fern community of Jaguarão Forest (08º 35' 49" S and 35º 15' 39" W), located in the district of Rio Formoso, Pernambuco, Brazil. A comparative analysis was made of the interior and edge of the fragment of forest, regarding the richness, abundance and diversity of ferns in the two areas. Six plots of 10 × 20 m were chosen, three in each area. A...
