Learning a second language is challenging, but mastering pronunciation is even more difficult. Researchers continuously seek new ways to improve students’ English abilities, such as listening and speaking, while ignoring the importance of pronunciation. After conducting a literature review, this article investigates the impact of corpora and two instructional methods on improving students’ pronunciation. The paper addresses how to teach pronunciation effectively in the context of English as a second language. According to the review, corpus resources, critical listening, and shadowing can all be used independently to enhance students’ proficiency in second language learning. Hence, an innovative Corpus-based Critical Listening and Shadowing model has been devised as an aid in the teaching of pronunciation by providing more specific suggestions for teachers and students, with the expectation that students will perform better once they have been taught pronunciation using the methodology. The current study’s findings have pedagogical and methodological implications for pronunciation teaching, learning and research. The implications and future directions of the innovative Corpus-based Critical Listening and Shadowing model are also discussed.

Chemical Looping Combustion (CLC) CO2 capture technology can be used to recover energy from municipal solid waste (MSW). In this study, techno-economic analysis of CLC of waste paper, PVC and their blends for electricity and heat generation was carried out. The process includes the chemical looping combustion section, carbon capture section and lastly, electricity generation section, and this was simulated using Chemcad software. Four scenarios were evaluated; IG-CLC (In-situ Gasification Chemical Looping Combustion) with electricity production only, and with combined heat and power (CHP), Chemical Looping Oxygen Uncoupling (CLOU) with electricity production and with combined heat and power (CHP). Based on a net capacity of 150 MW, the effect of waste paper, PVC and its blends on its net efficiency and LCOE was investigated for all four scenarios.
