A Study on Eco Friendly use of Recycled Rubber Tyres
The 20-40mm particle size of crushed aggregate and rubber aggregate showed 100% passing but river sand showed zero%. The 10 mm particle size of river sand showed 100% passing. Hydraulic conductivity ranges from 0.5 cm/sec (0.2 inches/sec) for compressed 10–38 mm (0.4–1.5 inches) shreds to more than 20 cm/sec (8 inches/sec) for 25–64 mm (1– 2.5 inches) loose shred. Thermal conductivity varies fr...
متن کاملDetermination of optimum filter in myocardial SPECT: A phantom study
Background: In myocardial perfusion SPECT imaging, images are degraded by photon attenuation, the distance-dependent collimator, detector response and photons scatter. Filters greatly affect quality of nuclear medicine images Materials and Methods: A phantom simulating heart left ventricle was built. About 1mCi of 99mTc was injected into the phantom. Images were taken from this phantom. Some fi...
متن کاملDetermination of optimum concentration of Diuron for the growth and bloom of the algae (Scenedesmus obliquus) in in Vitro condition
Growth rate of the green algae, Scenedesmus obliquus, influenced by Diuron, with the trade name of (Karmex) and chemical name of (N'-(3,4-Dichlorophenyl)-N,N-Dimethylurea), was examined in the present study. This study is performed in the laboratory of National Inland Waters Aquaculture Institute in Iran during 96 hours in 6 treatment and 3 replicates, using 500 cc Erlenmeyer Flasks. Measuremen...

متن کاملHazardous organic chemicals in rubber recycled tire playgrounds and pavers.
In this study, the presence of hazardous organic chemicals in surfaces containing recycled rubber tires is investigated. Direct material analyses using solvent extraction, as well as SPME analysis of the vapour phase above the sample, were carried out. Twenty-one rubber mulch samples were collected from nine different playgrounds. In addition, seven commercial samples of recycled rubber pavers ...
