To better understand the pattern of language use and classroom interactions, this sequential mixed-methods study investigated the teachers’ use of self-repair strategies based on their level of reflection. To this end, 33 Iranian EFL teachers were selected from various institutions in Tehran. Data for the quantitative phase were collected from the reflectivity questionnaire developed by Akbari,...

In order to protect the wood surface and improve properties of coatings, microcapsules with healable discoloration functions are produced, their function is obtained using shellac, which can be cured at room temperature, as repairing agent. this paper, self-made shellac color-changing were added varnish in different proportions form composite coating on a board, color difference was measured te...

As a vibration- free concrete, self- compacting concrete (SCC) can be easily used in the absence of consolidation, therefore; it is a good option for repairing and retrofitting concrete structures. The quality of repair layer is highly effective on a successful repair. Accordingly, in this study, factors affecting the quality of fiber-reinforced self-compacting concrete repair layer, including ...

Self-healing polymers composed of microencapsulated healing agents exhibit remarkable mechanical performance and regenerative ability, but are limited to autonomic repair of a single damage event in a given location. Self-healing is triggered by crack-induced rupture of the embedded capsules; thus, once a localized region is depleted of healing agent, further repair is precluded. Re-mendable po...
