qualitative and quantitative analyses of hospital and municipal solid waste are necessary for selecting the best and most appropriate method of health care collection, storage, transportation and disposal of this kind of wastes. quantitative and qualitative analyses of hospital and municipal wastes have been studied in ahwaz city during spring 1996. the amount of solid wastes in five regions of...

The radiation of tyre noise is computed with a mixed integral/ ray tracing approach called GRIM. It is simply an integral over the vibrating tyre, of the product of the known velocity by the full Green function which takes into account all the multiple reflections and diffraction between tyre, ground and car body. This Green function is calculated by means of a beam tracing program named ICARE,...

Abstract Given that the current ballasted tracks in Australia may not be able to support faster and significantly heavier freight trains as planned for future, imminent need innovative sustainable transport infrastructure is crucial. Over past two decades, a number of studies have been conducted by researchers Transport Research Centre (TRC) at University Technology Sydney (UTS) investigate abi...

Plastic and rubber tubing, of the types used frequently to convey anaesthetic gases to and from the patient, or anaesthetic waste gases out of the operating theatre, were assessed for their capacity to allow diffusion of halothane through the tube wall. The magnitude of this effect has been calculated in relation to pollution of the operating theatre atmosphere under different circumstances.

Reinforced rubber is thanks to its elastic and dissipative properties found in industrial applications such as isolators, flexible joints and tires. Its dissipative propertied comes from material related losses which have the effect that energy invested when deforming the material is not retained when returning it back to its initial state. The material losses are in turn caused by interactions...
