abstract the purpose of this study was to find out the effect of applying the principles of group-dynamic assessment (g-da) on learning of conditional structures in english by iranian efl learners at the intermediate level, which according to the formal educational system in iran, includes students who are in their second year of studying in high schools of koohdasht city. this study was a qua...
abstract the present study was an attempt to investigate the effect of critical thinking on writing ability of 60 iranian intermediate efl learners studying at chenar language institute in khuzestan, iran. to this end, the participants of the study were selected based on their performance in an pet test, a cornell critical thinking test form x and a pre-test of writing. the participants un...
Engineered Cementitious Composites (ECC) have superior mechanical and durability performance than conventional concrete. One of the major challenges producing ECC is to ensure appropriate rheology for uniform fibre distribution, which prerequisite its strain-hardening robustness. In this study, combined interactive effects polycarboxylate-based superplasticisers (SP) viscosity modifying admixtu...
This article proposes a new theory for predicting the crack bridging performance of random short fibers involved in cementitious composites. The current theoretical model for estimating crack bridging performance of Random Short Fiber Reinforced Cement Composites (RSFRCC) under tension is limited to specific constituent properties: friction dominant fiber-matrix interface and complete fiber pul...

This research article presents dual-frequency correlation models for predicting the growth of elasticity and flexural strength of engineered cementitious composites (ECCs) using microwave nondestructive inspection technique. Parallel measurements of microwave properties and mechanical properties of ECC specimens were firstly undertaken in the sense of cross-disciplinary experiments. Regression ...
