An Exercise‐Pollution Exposure Index for Assessing Inhaled Heavy Metal Exposure Along Urban Walking Routes

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Urban walking routes are promoted as health‐supportive environments, yet they may also act as microenvironments of pollutant exposure during physical activity. This study evaluated heavy metal exposure along urban walking routes by integrating road dust metal concentrations, conventional health risk assessment, deposited inhalation dose, and ...

Braking Performance of the Hydrodynamic Film Brake

SAE Technical Paper Series, 1989
<div class="htmlview paragraph">A brake has been designed for use on a class 8 tractor trailer which utilizes a hydrodynamic film of fluid between a series of rotors and stators to reduce wear and increase energy rejection capability. The hydrodynamic film brake or HFB was constructed and tested on a brake dynamometer and demonstrated a very low ...

Simulation Of Vehicle Brake Performance On Brake Dynamometer

SAE Technical Paper Series, 1984
<div class="htmlview paragraph">At an early stage of developments, brake performances are usually obtained from a simulation using a brake dynamometer. However the brake parts on the dynamometer will not operate at exactly the same temperature as that fitted to a road vehicle, because the cooling factors are different. Also the load on the brakes
