The effects of argon laser light on endotracheal tubes and gas mixtures have been studied. In recommended use accidental exposure to red rubber and PVC tubes caused minimal damage. Prolonged exposure of PVC tubing and a 2:1 nitrous oxide:oxygen mixture produced a minimal increase in temperature and no detectable increase in the concentration of higher oxides of nitrogen. Transparent endotrachea...

Abstract Nowadays the waste rubber problems are concerned due to environmental issues, storage, and recycling difficulty. However, base equipment has been widely used protect structures for vibrations - that generated by structure or induced from vicinity area bedrock into notable capability of absorbing energy. In this study, repeated-loading behaviour Sand Rubber Mixture (SRM) investigated re...

Both engineering practice and literature confirm that the high modulus asphalt mixture has superior performance. If modified, final can effectively improve service life of pavement. Therefore, design test this paper are trying to mix rubber powder BRA prepare Sup-13 mixture. Through a series experimental studies, discusses effect adding separately both into on its durability. The part mainly fo...

Mixtures of rigid sand particles and soft rubber (rubber chips) are prepared submitted to vertical taps in a confined cell investigate their propensity segregate. The mixture evolution is characterized by means image analysis slices obtained gelification technique. We show that, case equally sized particles, the tend migrate towards bottom system. Yet, segregation not complete reduced when frac...

Abstract Recycling tires is one of the eco-friendly way for reducing environmental problems. Incorporating crumb rubber in asphalt mixtures an alternative reusing end-of-life road construction. The main purpose this study to evaluate cold mix incorporating as a substitute part fine aggregates. In study, aggregate gradations design were selected according specification, Dense Graded Emulsion Mix...
