This study investigates the utilization of nano-composite hydrogels for the removal of methyl violet from aqueous solutions, leveraging a Fenton-like reaction mechanism. The nano-composite hydrogel demonstrated exceptional efficiency in dye removal, attributed to the synergistic effects of the hydrogel matrix and the catalytic activity of embedded nano-particles. This process generates hydroxyl radicals under mild conditions, leading to the effective breakdown of various industrial dyes. The kinetics of dye removal, the reusability of the nano-composite, and the influence of operational parameters such as different amounts of nano-composite, pH, , temperature, and dye concentration were systematically explored. The findings underscore the potential of nano-composite hydrogel as a promising, environmentally friendly solution for wastewater treatment and dye removal.

Reading plays a vital role in English language acquisition as it helps learners improve vocabulary, grammar, and comprehension skills. Through reading, students are exposed to various sentence structures, idiomatic expressions, and contextual usage of words, which enhances their language proficiency. It also increases motivation and interest in learning, especially when learners choose materials that match their interests and level. Reading not only develops language input but also supports other language skills such as writing and speaking. Furthermore, it encourages independent learning and critical thinking. Effective reading strategies and regular reading habits can significantly speed up the process of acquiring English. Therefore, reading is considered one of the most effective and accessible tools in second language learning.

Атрофдаги оламни билиш - унинг моделларини яратишдан иборат. Улар ушбу олам объектлари билан бизнинг ўзаро таъсиримиз оқибатларини кўриш имконини беради. Моделларни яратиш инсон тафаккурининг ташкилий тузилишини такомиллаштириш жараёни ҳисобланади. Мазкур психологик ташкилий тузилиш мақсадга йўналган ҳаракатлар кўринишида моддийликка айланади, уларни инсон ўзида мавжуд моделлар асосида амалга оширади. Ушбу мақолада математик моделлаштиришнинг асосий масалалари ҳақида фикрлар ёритилган.

The teaching of speech acts in the English language, especially as a second or foreign language (ESL/EFL), must employ a manner that is thoroughly systematic, well-grounded theoretically and innovative if the situation is to guarantee the learners' effective acquisition of communicative competence. The aim was, among other objectives, to create didactic systems and to design instructional materials that might improve students' abilities, directly or indirectly, to know and then apply in practice these pragmatic rules. Drawing from Speech Act Theory, Politeness Theory, and Task-Based Language Teaching (TBLT), the present study's intent was to evaluate methods which could serve as interactive, authentic, and culture-sensitive resources for pedagogical implementation in support of pragmatic competence. Data sources comprised classroom observations, role-plays, case studies, and reflective analyses. From the study, it has been learned that the integration of multimedia resources, real-life scenarios, and collaborative tasks strongly enhanced learners' competences in enacting acts of conversational cooperation: invitations, refusals, and requests. The study concludes with practical suggestions on didactic designs meant to direct the course of learners with respect to pragmalinguistic fluency and socialversible creativity.
