Dengue fever is increasing in geographical range, spread by invasion of its vector mosquitoes. The trade in second-hand tires has been implicated as a factor in this process because they act as mobile reservoirs of mosquito eggs and larvae. Regional transportation of tires can create linkages between rural areas with dengue and disease-free urban areas, potentially giving rise to outbreaks even...

Introduction The production of scrap tires only in the EU, USA and Japan is around 6 million tones per year. As the associated automotive industries grow the huge quantity of waste tires presently produced in the world will certainly increase in the future [1]. Thus the disposal of scrap tires becomes a serious environmental problem. The production of activated carbons from solid wastes is one ...

2 Executive Summary The purpose of this paper is to familiarize the reader with the paving material asphalt-rubber (A-R) by providing historical perspective on its development and obstacles to its development. A-R has been a constant and stable market for crumb rubber producers in the United States most significantly within the vicinity of Arizona, California, and Florida. Agencies use A-R beca...

Tires equipped with sensors, the so-called "intelligent tires", can provide vital information for control systems, drivers and external users. In this research, tire dynamic strain characteristics in cornering conditions are collected and analysed in relation to the variation of tire working conditions, such as inflation pressure, rolling speed, vertical load and slip angle. An experimental tir...

Damaged tires cause many fatal car accidents that claim lives worldwide. The use of a regular digital camera that can generate JPEG images, so as to become aware of damaged tires, is proposed. The digital camera repeatedly takes pictures of the car’s tires. When there is a drastic change in a particular block of JPEG, the value of many of its frequency coefficients will be high and it will be c...

The so-called intelligent tires are one of the most promising research fields for automotive engineers. These tires are equipped with sensors which provide information about vehicle dynamics. Up to now, the commercial intelligent tires only provide information about inflation pressure and their contribution to stability control systems is currently very limited. Nowadays one of the major proble...

Nacrtak The motion resistance ratio, gross traction ratio and net traction ratio of a wheel cable skidder were determined and mathematical models derived for three tire inflation pressure values with or without tire chains on forest road in mountainous conditions. The motion resistance ratio increases with the increase of tire inflation pressure. On the contrary, the gross traction ratio increa...

The intensity and prevalence of parasitism by Ascogregarina barretti (Vavra) in Aedes triseriatus (Say) did not differ between tires and tree holes in field samples taken in September 1996. There was significant variation in the intensity of parasitism among containers that was not significantly correlated with the pH, conductivity, or temperature of the container water. In an experiment manipu...
