15 صفحه اولChemical Recycling of Polymer Materials
After the first life cycle of plastics various recycling processes are available for further utilization of these valuable materials. For an ecologically and economically satisfying solution the most suitable process has to be chosen. In chemical recycling polymers are degraded to basic chemical substances which can be reused in the petrochemical industry. For soiled waste plastics or waste pla...
متن کاملToxicity of endodontic filling materials
The toxicity of endodontic materials is reviewed. The patient may be exposed by constituents leaching from the unset and set sealer and by accidental overfilling of the root canal. For most patients the exposure is believed to be below the threshold for a toxic effect. Most sealers exhibited a cytotoxic response, especially unset and the responses diminished with time after setting. Unset and n...
متن کاملAutomobile Recycling Policy: Background Materials
The issue of automobile recyclability is a problem with complex ramifications for car makers world-wide. Confronted with increasingly stringent fuel economy, emissions, and safety standards, recyclability is an attribute which can limit the ability of the automaker to meet these other goals economically. Nevertheless, social and political pressures upon the industry require that it responds to ...
متن کاملreview of root-end filling materials
background and aim: the main goal of endodontic treatments is eliminating the etiologic factors of pulpal and periapical diseases as well as maintaining this condition via providing a hermetic seal between periodontium and root canal system. if these were not possible through orthograde approach, periradicular surgery and root-end filling are indicated. review of literature: different materials...
