The main sources of non-exhaust vehicular emissions that contribute to road dust are tire, brake and clutch wear, road surface wear, and other vehicle and road component degradation. This study is an attempt to identify and investigate heavy metals in urban and motorway road dusts as well as in dust from brake linings and tires. Road dust was collected from sections of the A-4 motorway in Polan...

In 1999, National Highway Traffic Safety Administration (NHTSA) researchers theorized that substantial improvements could be made in the braking performance of medium and heavy trucks. Therefore, NHTSA initiated a multi-year research program to learn what improvements in stopping performance could be achieved using advanced, but currently available, brake technology for medium and heavy trucks....

ourselves. While the emergence of infections such as trated, and some of the few figures that are included smallpox has been linked to the development of the better explained. Even the novels of B.B. Jorden manage first numerically significant human communities, there to include a few drawings to illustrate, for example, the seems to be little indication that these or other virus life cycle of ...

The Arp2/3 complex is a powerful nucleator of actin filaments when activated. A recent study has now revealed that this complex is not only subject to positive control but that there also exists a brake on its activity. This brake can suppress both the basal activity of the Arp2/3 complex as well as its activation by nucleation-promoting factors.

The statistical data published by National Police Agency, Taiwan, indicated that the motorcycle induced the highest accident rate, and drunk driving ranked first among the traffic fatality causes in 2007. The high traffic accident rate was attributed to the alcohol decaying driver reaction and the increase of frequency of using motorcycle in daily life as the car parking space and driving cost ...

Abstract Braking system is one of the most important component for any vehicle, it convert kinetic and potential energy vehicle into heat, which allow to stop. During braking operation, disc its components has experience fast change in temperatures, heat absorbed dissipated must be effective, maintain a high performance system. That’s why brake cooling an area research top manufacturers needs p...

Abstract. Aluminium-matrix composites (AMC) are produced in order to improve specific properties (e.g. mechanical, thermal or tribological) of the matrix alloy using discontinuous reinforcements like fibres particles. If functional requirements application components such as brake discs have be met, reinforcement contents more than 35 % may required. Therefore, a new manufacturing route is curr...
