Reuse of tire crumb in sport facilities is currently a very cost-effective waste management measure. Considering that incorporation of the waste materials in artificial turf would be facilitated if the rubber materials were already colored green, coatings were specifically developed for this purpose. This paper presents an experimental toxicological and environmental assessment aimed at compari...
Currently, in the United States there is a growing gap between domestic oil production and consumption. The Department of Energy has developed a modeling tool (known as VISION) that projects future consumption by the transportation sector through the year 2050. This paper uses the VISION model to show that an energy savings of 3.8 billion gallons per year can be achieved with a 2.5% improvement...
Bicycling crashes on streetcar (tram) or train tracks: mixed methods to identify prevention measures
BACKGROUND Streetcar or train tracks in urban areas are difficult for bicyclists to negotiate and are a cause of crashes and injuries. This study used mixed methods to identify measures to prevent such crashes, by examining track-related crashes that resulted in injuries to cyclists, and obtaining information from the local transit agency and bike shops. METHODS We compared personal, trip, an...
Nowadays, non-pneumatic tires are becoming an increasingly likely alternative to pneumatic tires. The function of compressed air has been taken over by the belt and elastic structure (materials used shape components). research presented in paper was carried out quasi-static conditions. research's aim compare radial stiffness, hysteresis selected parameters contact patch two four interchangeably...
Background and Aim: Heavy metals have been recognized as very poisonous elements and their discharge into water sources can cause damaging effects on human and environmental health. The present study aimed at producing activated carbon from scrap tires and using it in removing Pb+2 from synthetic aqueous solutions. Materials and Methods: In this experimental study, activated carbon p...
