It has been shown recently that the shimmy motion of towed wheels can be predicted in a wide range of parameters by means of the so-called memory effect of tyres. This delay effect is related to the existence of a travelling-wave-like motion of the tyre points in contact with the ground relative to the wheel. This study shows that the dynamics within the small-scale contact patch can have an es...

HISTORY: The SIDS Dossier and Testing Plan were reviewed at the 3rd SIDS Review Meeting where the following SIDS Testing Plan was agreed: no testing () testing (x) Testing on developmental toxicity/teratogenicity was underway at the time of the review meeting. The SIDS Initial Assessment Report was discusse d at SIAM 6 in 1997. It was recommended that the report should be re-drafted and present...

Chars produced from the pyrolysis of different waste materials have been investigated in terms of their use as a catalyst for the catalytic cracking of biomass pyrolysis gases during the two-stage pyrolysis-gasification of biomass. The chars were produced from the pyrolysis of waste tyres, refused derived fuel and biomass in the form of date stones. The results showed that the hydrocarbon tar y...

j 17 A p il 2 0 17 T by the endemic Aedes aegypti and A. albopictus vectors, together with increasing travel by Australians to dengue-endemic destinations. From 1991 to 2012, most cases of notified dengue in Australia were related to overseas travel, with respective increases in 2010 and 2011 of 298% and 155% above the 5-year mean notification rate; the risk of dengue in travellers returning fr...

Due to limited energy resources, high energy demand and constrict emission norms led the researchers to find alternative fuel for IC engines. Due to the fossil fuel crisis, the development of alternative fuel technologies has drawn more attraction to deliver the replacement of fossil fuel. Many alternative fuels have been developed and commercialized like alcohols, biodiesel, LPG, CNG etc. pyro...

Go-karts are popular sport mini-car in western countries, and there are gaining prominence in developing countries such as Nigeria. Its performance is determined by the chassis design and the braking system is its lifeline. Because of the lack of a suspension system and differentials, a good chassis must be able to bend and twist. This Go-kart is powered by a Yamaha Vino Automatic Petrol 2-str...

With rapidly changing computer and IT and much of the technology finding way into cars, cars are undergoing histrionic changes in their ability. Although some cars have provisions for deciding to either generate warnings for the human driver or control the car free, they usually must make these decisions in real time with only incomplete information. So, it is important that human drivers still...
