The properties of the beta batteries are compared, which are made on the basis of the different β-isotopes with beta decay. Tritium and Ni-63 make it possible to make β-sources of high activity, without harmful associated emissions, with low self-absorption, emitting high-energy β-electrons that penetrate deep into the semiconductor and generate a large number of electron-hole pairs. The efficiency of beta batteries needs to be analyzed based on the real energy distribution of β-electrons. It makes possible to obtain the real value of the energy absorbed inside the β-source, correctly estimate the amount of self-absorption of the β-electrons and part of the β-electronsthere is a penetrate into the semiconductor, the number of electrons and holes that are generated in the semiconductor, and the magnitude of the idling voltage. Formulas for these quantities are calculated in this paper.

Water scarcity, particularly in arid and semi-arid regions, is a critical issue affecting forest management. This study investigates the effects of drought stress on the water requirement and morphological characteristics of two important tree species Turkish pine and Chinaberry. Using a factorial design, the study examines the impact of three age stages (one-year-old, three-year-old, and five-year-old plants) and three levels of drought stress on these species. Microlysimeters of varying sizes were employed to simulate different drought conditions. Soil moisture was monitored to show the effect of the various irrigation schedules. The study also calculated reference crop evapotranspiration (ET₀) using the PMF-56 method and developed plant coefficients (Kc) for the species. Results showed that evapotranspiration increased with soil moisture, peaking during summer and decreasing in winter. Turkish pine exhibited higher plant ET than Chinaberry, particularly among one-year-old seedlings. Drought stress significantly reduced evapotranspiration and water uses for both species, highlighting the importance of efficient water management in afforestation projects. The findings underscore the necessity of selecting drought-resistant species and optimizing irrigation practices to enhance the sustainability of green spaces in arid regions. These insights are crucial for improving urban forestry management and mitigating the impacts of water scarcity in Iran and similar climates globally.

Major principles of organizational management like unity of command and unity of direction are quite important to foster co-ordination and efficiency in organizations. Since Islamic management is an offshoot of the modern Western management theories these principles have considerable relevance to Islamic management as well. This paper aims to discover how Islamic principles can solve modern problems of organizational management in order to demonstrate an interdependent system that teaches ethics and management. This paper attempts to offer an analytical discussion regarding Islamic views on the challenges that emerge regarding the need for cohesion in managing any organization. On the basis of a conceptual review, it highlights how unity of command and unity of direction can influence inspiring better management at all levels positively. Such clarification tries to elicit the Islamic interpretation that may lead to increased workforce commitment due to their motivation emanating from religion, contribute principles that will benefit the value addition process of labor and management’s decision-making process towards wider organizational goals, and enrich literature on management from Islamic principles and thoughts. This text succinctly examines the principles of unity of command and unity of direction that promote the development of management work ethics and the implications of Islamic management. The paper reviews the principles of unity of command and unity of direction as derived from The Holy Qur’an and Hadith, and examines various empirical studies conducted in different countries. These discussions subsequently bring out that the Islamic approach is comprehensive and practically relevant in the interest of present-day organizations. The paper concludes that intention and purity of hearts, regardless of the leadership styles of management, will direct the leaders and workforce to continually strive hard and give their best in their organizational management functions.

This research looks into the differences in technological practices across Gen-X, Gen-Y, and Gen-Z employees in the workplace, with an emphasis on motivation, communication, collaboration, and productivity gaps. The study uses a systematic literature review to identify factors that contribute to these variations, taking into account each generation’s distinct experiences, communication methods, working attitudes, and cultural backgrounds. Bridging generational gaps, providing ongoing training, and incorporating cross-generational and technology-enhanced practices are all required in today’s workplace. This study compares the dominating workplace generations, Gen-X and Gen-Y, with the emerging Gen-Z. A review of the literature from 2010 to 2023, which was narrowed down from 1307 to 20 significant studies, emphasizes the importance of organizational management adapting to generational changes in order to increase productivity and maintain a healthy workplace. The study emphasizes the need of creating effective solutions for handling generational variations in workplace.
