Evaluation of the separation involved in recycling end-of-life (EOL) electronic equipment
… to separate two specific EOL plastics, namely High Impact Polystyrene (HIPS) and Acrylonitrile Butadiene Styrene copolymer (ABS).;The objective of this research was to investigate composition of keyboards and casings of personal computers, and other EOL components, as representative of …

Numerical Model for the Lateral Compression Response of a Plastic Cup
… MSC.Patran, ABAQUS/CAE, and ABAQUS/Standard. The high impact polystyrene material of the cup is modeled as linear elastic, considering isotropic and orthotropic material behavior. The structural model of the cup is a truncated conical shell including a ring at the open end of the cup and …

Development and Commissioning of An Independent Peer Review System For A Small Animal Irradiator
… audit. Two mouse phantoms were machined from high impact polystyrene; one accommodated three thermoluminescent dosimeters (TLD) and the other an Exradin A1SL 0.053 cc ion chamber (Standard Imaging, Middleton, WI) for cross-comparison with the TLD. An acrylic irradiation stand was constructed …

Ultrasonic wave reflection measurements on self-compacting pastes and concretes
… impedance close to that of cement paste, high impact polystyrene, was chosen to obtain sensitive results from the early hydration period. Criteria for initial and final set developed by our group in a prior study were used to compute setting times by UWR. UWR results were compared with …

Development and Implementation of The Use of Optically Stimulated Luminescent Detectors In The Radiological Physics Center Anthropomorphic Quality Assurance Phantoms
… for TLD in the QA phantoms. A 10 cm diameter high-impact polystyrene spherical phantom was designed and constructed to hold an OSLD to study the angular response of the dosimeter under the simplest of circumstances for both coplanar and non-coplanar treatment deliveries. OSLD were irradiated …

Green composites from castor oil and renewable reinforcing materials: maleated castor oil-polystyrene matrix reinforced with greige fibre
… its use does not deplete food sources and it has high chemical reactivity. In this study, medical grade castor oil was maleated by the addition of maleic anhydride to form maleated castor oil (MACO). This reaction was performed at 98 ˚C for five hours. The completion of the reaction was monitored …
