This research paper explores the influence of first-order chemical reactions on the sustainable properties of electrically conducting magnetohydrodynamic (MHD) fluids in a vertical channel with the unique characteristics of Jeffrey fluid flow. The mathematical model of MHD flow with Jeffrey fluid and chemical reaction incorporates the impacts of viscous dissipation, Joule heating, and a non-Newtonian fluid model with viscoelastic properties in the flow regions. The governing equations of the flow field were solved using the finite difference method, and the impacts of flow parameters on the flow characteristics were discussed numerically using a graphical representation. It’s revealed that increasing the Jeffrey parameter results in a decline in the velocity field profiles. Also, species concentration field profiles decline with higher values of the destruction chemical reaction parameter. The findings of this study have significant implications for various engineering applications, including energy generation, aerospace engineering, and material processing. Additionally, the inclusion of Jeffrey’s fluid flow introduces a viscoelastic component, enhancing the complexity of the fluid dynamics.

This paper explores the ritual practices associated with Beiyuan Tribute Tea production in Jianzhou, Fujian, China. Beiyuan Tribute Tea, a historically significant tea, originated in the Tang Dynasty, flourished during the Song Dynasty, and experienced a decline in the Ming Dynasty, reproduced in contemporary times. The tea’s production involved intricate rituals that not only enhanced its quality but also embedded it deeply into the socio-cultural and religious fabric of the time. These rituals, encompassing aspects of religious reverence, craftsmanship, and social etiquette, played a crucial role in the tea’s esteemed status as a tribute to Chinese emperors in history. The study utilized ethnographic methods, including participant observation, in-depth interviews with 17 people, and document analysis, to capture the rich, contextual details of the tea production process. The study delves into the historical context, production techniques, and symbolic meanings of the rituals, highlighting their impact on the broader cultural heritage of Chinese tea. The recent revival efforts of these traditions underscore their enduring significance and offer insights into the cultural continuity and adaptation in contemporary tea practices.

Art studies and activities for older adults have received significantly less attention as a result of prohibitively expensive materials that are unfit for commercial use, and research utilizing digital technology to investigate artistic activities for older adults is extremely limited. The purpose of this article is to analyze and review recent research in these fields to summarize the current trends. The literature review comprised 108 articles from databases that included Scopus, ScienceDirect, and Google Scholar. The papers were subjected to a thorough examination by the VOSviewer program and researchers, who utilized content analysis to classify them into four themes: 1) inclusive design; 2) accessibility; 3) digital art therapy and 4) digital technology environments. Further investigation and development are necessary to propose a novel approach to instructing senior-level art utilizing cutting-edge technologies, which could be enhanced by the findings of this review article.
