Flexural Performance Of Nsm-Cfrp Strengthened Corroded Rc Prisms Under Freeze-Thaw And Wet-Dry Cycles, Zainab Abdulsattar Ghali, Maan S. Hassan

Engineering and Technology Journal

This study investigates the combined effects of corrosion level and environmental exposure on flexural behaviour of corroded reinforced concrete (RC) prisms repaired with self-compacted concrete (SCC) and strengthened with a near-surface-mounted (NSM) carbon fibre-reinforced polymer (CFRP) system. Two accelerated corrosion levels (10% and 30%) were introduced before repair. The damaged concrete cover was removed and recast using self-compacting concrete (SCC), followed by NSM-CFRP strengthening. The repaired prisms were then exposed to standard laboratory conditions (ST), 300 freeze-thaw (FT) cycles, or 50 wet-dry (DW) cycles before flexural testing. Corrosion reduced the stiffness and load-carrying capacity of the RC prisms. The NSM-CFRP …

A Framework For Teaching Maya Aspect System: Pedagogical Strategies For Maya Grammar, Quetzil E. Castañeda

Journal of Maya Heritage

Abstract. Maya, an Indigenous language spoken primarily in Mexico’s Yucatán Peninsula, remains under-resourced in materials for second-language and heritage-language learners. Its agglutinative morphology, split ergativity, and aspect system pose particular pedagogical challenges, especially when Maya grammar is explained through Spanish or English tense categories. Based on a critical review of existing teaching resources and the author’s more than twenty years of experience teaching Maya, this article proposes a pedagogical framework for understanding its aspect grammar. Rather than organizing verbal morphology around tense, the framework distinguishes four principal conjugational forms: Ongoing Incomplete, Simple Past, Completed Present, and Subjunctive. It also introduces …
