Seismic hazards remained as a challenge to engineers over ages. In order to reduce loss of life and damage to property due to earthquake, several techniques have been developed among which Seismic Isolation technique using Elastomeric Isolators has gained high acceptance and becoming popular all over the world, due to its simplicity, reliability and overall cost effectiveness. Seismic Isolation...

Abstract We study the influence of rubber transfer films on sliding friction between rectangular blocks and a concrete surface. present experimental results for coefficient compound surface contaminated by another compound, two different pairs (A, B) (C, D) compounds. For same compounds, we theory which illustrate relative importance viscoelastic adhesive contribution to friction. correlate cal...

this research work is devoted to experimental and theoretical evaluations of a hybrid constitutive model which was designed to simulate the mechanical behavior of a tread rubber compound. the model is a combination of yeoh hyperelastic model with a strain-rate hysteresis model developed by bergstrom and boyce. the parameters of the yeoh model were calibrated from experimental data of the astm d...

Along with the developing technology in rubber industry, use of natural and synthetic rubbers as well liquid has increased significantly recent years. The formulation tread compound, which directly affects performance a tire, is generally produced from rubbers. Intensive scientific studies have been carried out on because they reduce consumption process oils used tire production phase increase ...

5-Phospho-d-ribosyl-1-diphosphate (PRPP) synthase (PRS) catalyzes the biosynthesis of PRPP, which is an important compound of metabolism in most organisms. However, no PRS genes have been cloned, let alone studied for their biological function in rubber tree. In this study, we identify a novel protein (PRS4) that interacts in vivo with rubber tree anaphase promoting complex/cyclosome (APC/C) su...

Waste utilization has gained more and more interest. In this study, crumb rubber and diatomite were used to modify asphalt binder and the short-term aging effects on the properties of modified asphalts were evaluated. Three kinds of modified asphalt were prepared; they are diatomite modified asphalt (DA), crumb rubber modified asphalt (RA), and diatomite and crumb rubber compound modified aspha...
