Toward a Physical Interpretation of π: The Fundamental Ratio Linking Spatial Periodicity and Quantum Energy
(Publisher, 2025-11-07) Barack Ndenga
The mathematical constant π, traditionally regarded as a purely geometric ratio, may in fact encode a fundamental physical relationship between spatial periodicity and quantized energy. In this work, I explore the emergence of π within a set of canonical quantum systems—such as the particle in a box, the quantum ring, and quantized field modes—to investigate its deeper physical meaning. Through analytical derivations, I demonstrate that π systematically arises from the imposition of boundary conditions that ensure wave coherence and spatial quantization. These constraints translate discrete spatial modes into continuous energy spectra via factors containing π, suggesting that π is not an incidental numerical constant but a universal invariant of quantization itself. This interpretation elevates π from a geometric artifact to a conversion constant mediating the transformation between spatial periodicity and energetic discreteness. The results imply that π governs the intrinsic harmony between geometry, frequency, and energy in all physical systems—from microscopic quantum oscillators to macroscopic resonant fields. Ultimately, π may represent a universal symmetry parameter underpinning the quantization of space, time, and energy, bridging geometry and physics through a single invariant principle.

Molecular mechanism of tRNA modification enzymes in bacterial pathogenicity and their development in antibiotic resistance
(2025-11-07) Swati Dixit
Antibiotic resistance is a global challenge still prevailing in many parts. While recent advancements in research and technology are helping to combat the challenge, some undermined and unexplored molecular factors of bacteria are interfering with the broad spectrum targeting of the pathogenicity. tRNA modifications and their enzymes are critical components of the bacterial regulatory mechanism and translation apparatus but their importance in the therapeutics of antibiotic resistance in bacterial human diseases has been elusive. Various tRNA modifications, along with their associated modifying enzymes, are integral to bacterial survival, particularly under adverse environmental conditions. Bacterial tRNA molecule exhibits diversity in modifications, while they are mainly concentrated at tRNA core and anticodon-loop (ACL) regions. This review examines the tRNA modifications in bacteria, including their influence on tRNA stability, protein translation, and their critical involvement in pathogenicity and virulence, encompassing processes such as cell cycle regulation, toxin production, outer membrane protein synthesis, and oxidative stress response. This review also emphasizes emerging strategies and challenges in targeting tRNA-modifying enzymes exclusive to pathogenicity in bacteria paving the foundation for antimicrobial resistance.

Quality culture in Tanzanian schools: A scoping Review
(2025-11-06) Revocatus C Kuluchumila; Ezra Nathanael Ntazoya
The present scoping research aimed to investigate how and the degree to which quality culture is embedded in Tanzanian schools. The search engines on quality culture came up with 39 published and unpublished sources. The reviewed sources revealed availability of education infrastructure to be one of key factors on improving quality culture in schools. The research results indicated further that improving the culture of community engagement could facilitate timely construction of classes. Results revealed also that, low commitment of teachers contributed to poor quality in education. Moreover, good teacher-students relationship was revealed as a significant factor on building the learning culture. Regarding the extent to which the linkage between the formal framework and human dynamics adds to building quality culture in schools, research findings indicated that, the community was deprived on engaging in various school activities to promote quality learning. Other research results indicated that majority of teachers lacked competence on integrating ICT in the teaching and learning process. Last but not least, school leadership to a greater degree lacked competence on building strong positive quality culture in their respective schools. It was generally revealed by reviewed studies that numerous elements of quality culture were embedded in Tanzanian schools.
