Among various dissipating mechanisms, the viscoelastic effect of rubber material on creation of rolling resistance is responsible for 10-33% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with improving the fuel consumption of vehicles and resultantly energy savage. Hysteretic loss is a fraction of...

One of the biggest challenges recent civil engineering is need to make it sustainable by implementing environmentally friendly and cost-effective solutions. The search for new materials technologies an important current issue also in strengthening soft soils. In soil stabilization process, conventional (cement lime) are being replaced waste materials, such as stone slurry waste, spent coffee gr...

BACKGROUND Primary tracheal tumors occur infrequently, accounting for less than 0.1% of all tumors. Adenoid cystic carcinoma (ACC) is the second most common type of malignancy of the trachea after squamous cell carcinoma (SCC). Little has been reported on the risk factors for tracheal ACC. The purpose of this study is to describe a case of tracheal ACC in a patient who had been exposed to rubbe...

We have measured the surface topography and calculated the surface roughness power spectrum for an asphalt road surface. For the same surface we have measured the friction for a tire tread compound for velocities 10(-6) m s(-1) < v < 10(-3) m s(-1) at three different temperatures (at -8 °C, 20 °C and 48 °C). The friction data was shifted using the bulk viscoelasticity shift factor a(T) to form ...

Abstract Improper disposal and accumulation of waste tire rubbers have posed a serious threat to the development circular economy, sustainable environment, human health. In light drawback current management tires, recycling transformation reclaimed rubber (RR) into valuable end products has received significant attention from industries academic field. Herein, we propose facile method reuse RR ...

in which ground glass connections could not be used because of the large size of the flasks, it was found that benzene extracts of rubber stoppers previously washed with ether and methanol still contained blue-green fluorescing substances. These extracts had the ultraviolet absorption spectra of carcinogenic hydrocarbons and other compounds of interest. This discovery seemed of such great possi...

Today, rapid economic and industrial growth generates increasing amounts of waste materials such as waste tyre rubber. Attempts to inspire a green technology which is more environmentally friendly that can produce economic value are a major consideration in the utilization of waste materials. The aim of this study is to evaluate the effect of waste tyre rubber (crumb rubber modifier (CRM)), in ...

Soils are called problematic soils when they do not have sufficient bearing strength to provide a founda-tion for the structures be built on them and these types of need improved with appropriate methods depending their properties. Improvement applied strengthen often cause financial burden. Recently, there studies about use waste rubber tires, which pose an environ-mental risk during storage, ...
