This research introduces a novel framework integrating stochastic finite element analysis (FEA) with advanced circular statistical methods to optimize heat pump efficiency under material uncertainties. The proposed methodologies and optimization focus on balancing the mean efficiency and variability by adjusting the concentration parameter of the Von Mises distribution, which models directional variability in thermal conductivity. The study highlights the superiority of the Von Mises distribution in achieving more consistent and efficient thermal performance compared to the uniform distribution. We also conducted a sensitivity analysis of the parameters for further insights. The results show that optimal tuning of the concentration parameter can significantly reduce efficiency variability while maintaining a mean efficiency above the desired threshold. This demonstrates the importance of considering both stochastic effects and directional consistency in thermal systems, providing robust and reliable design strategies.

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.

Despite the unpleasant conditions, such as lower and insufficient wages, higher working hours, longer length of service, total absence of casual workers union, indirect employment aided by the bank’s top directors, etc., casual workers are highly committed in performing their roles and achieving their organizational goals. Neoliberal theory and Equity theory were used for guidance in this study. The study employed qualitative analysis style; Total of ten banks were selected as a sample of the study involving sixty participants who were all casual workers; twenty-four female and the remaining thirty-six were male, have been selected using purposeful sampling. Content analysis was used as the method of data analysis. The study shows some of the functions performed by the casual workers of Nigerian banks include quick client service, amenability to work, client care services, opening of accounts, marketing, and timely task completion. Others include furnishing prompt client service, being prepared to work, and finishing assignments on schedule., thus, the study concludes that despite the outstanding performance of casual workers in achieving their organizational pretensions, they’re largely exploited. The recommendation of the study is that employment should be grounded on fair stipend, safety at work and protection for casual workers, in short, work should encompass fairness, equivalency, and freedom of association. Also, Payment of the benefit accumulated by the casual workers should be linked directly between casual workers and their associations.

The impact of the coronavirus outbreak was seen all over the world in all sectors. In the case of Bangladesh, it was not free of threats. Like all other sectors, the economic, social, and educational sectors were under serious threat. This study examined the effects of COVID-19 on the lives of Bangladeshi students, with a particular focus on their idealized portrayals of plans, daily routines, social interactions, and mental well-being. This research also investigated the influence of COVID-19 on education, social life, and other sectors and how the government was dealing with this unprecedented situation and these elevation challenges. A mixed-methods approach was adopted for this research. A total of 90 students from Bangladeshi higher educational institutions were taken as a sample size using the random sampling method. SPSS software was used for data analysis. The study’s quantitative results showed that Bangladeshi students faced challenges related to teaching, learning, and social distancing during the COVID-19 pandemic. Additionally, the study revealed that the pandemic adversely affected higher education in Bangladesh. Rebels and concerned citizens from all parts of the state must work together to move forward. COVID-19 has had a natural effect on education and almost every other field. The need for social distancing has pushed the education system to change because of social distancing. Many educational institutions worldwide have shuttered their campuses and relocated their teaching and learning online.

There is a large literature on public-private-partnership, covering many different areas and aspects. This article deals with a specific but important aspect: the decision-making mechanisms to choose the management of PPP enterprises. In this sector, a suitable choice of managers is of particular importance because the persons chosen must balance the public and private interests. This is often difficult to achieve. Two new procedures are discussed, “Directed Random Choice” and “Rotating CEOs”. In each case, the advantages and disadvantages of the procedure of choosing the managers of PPP enterprises are discussed and evaluated. It is concluded that the two novel mechanisms should be seriously considered when choosing the managers of PPP enterprises.

Some developmental projects are created by people-private partnerships (PPP), particularly where recovery is acquirable by levying the users. Such PPPs are successful for construction of roads, bridges, running toilet facilities and conveyance facility in mode of use and pay. Likewise, public-scientist partnerships (PSPs) will be successful, where monitored impacts can be used to derive benefit. But such example cases are not so popular in utilizing new research results and derive benefits from natural resources and enhance productivity. There is a demand for similar partnership projects in research area. In this study modality of the PSP to create boost engine for natural resource conservation and bring economic prosperity is established. A novel PSP launch was synthesized on useful food crop viz. finger millet (Elusiane corcona (l)), which has been known since long past, and now is regaining popularity. It was possible to enhance additional annual production of 5.755 million tonnes of finger millet grain, equivalent to additional income of Rs 11,510 crores. Against this the scientist partnership share was 0.49x million tonnes grain and economic equivalency of Rs 992 crores, which was just 7–8%, with same level of input in agriculture. Additional benefits were sustainability of production and resources consecration, reduction of greenhouse gas emission (GHGs), particularly nitrous oxide (N₂O), largely emanating from agriculture and responsible for depletion of ozone layer. The finger millet stiff stem will be useable for production of ply-board filling material that will be innovative building material for housing and infrastructure developments and making furniture.
