Abstract

This study looks at the astronomical and cultural significance of the New Year's festivities of six ethnic groups in Ethiopia: the Oromo, Sidama, Gurage, Welayeta, Amhara, and Tigray peoples. In September, each group observes the Ethiopian New Year by the Enkutatash celebration, which is based on traditional practices and the Ethiopian solar calendar. The study examines the effects of astronomical phenomena, such as moon phases and the solar cycle, on the timekeeping practices and New Year's festivities of these diverse cultures. Based on the biblical tale of Noah's dove, which stands for hope and renewal, the study emphasizes themes of regeneration and the need for new beginnings. Customs such as the Oromo Waqeffanna, Welayeta Gifata celebration, and the Amhara and Tigray peoples, demonstrate the relationship between astronomical observations, agricultural cycles, and cultural rites. The study also explores the Yewa Sureke celebration, which the Zeyise people of southern Ethiopia observe to commemorate the start of the agricultural year on a lunar calendar. The festival, which incorporates feasting, music, and rites of reverence for ancestors to fortify cultural identity, represents the resuscitation of spiritual and communal relationships. Finally, these results show how New Year's festivities preserve cultural continuity, foster social cohesiveness, and link contemporary customs to astronomical and historical contexts.

Abstract

The Astronic Tradition explores the profound influence of celestial observation on religious beliefs and practices across cultures. This study investigates how ancient civilizations utilized astronomical phenomena to shape their spiritual frameworks and the ongoing relevance of these traditions in contemporary religious contexts. Historical evidence reveals that societies such as the Mesopotamians and Egyptians closely monitored celestial events, integrating them into their calendars and rituals. This study highlights the common human experience of looking to the cosmos for significance by contrasting how major religions Hinduism, Christianity, and Islam interpret celestial phenomena. It also fills the gaps in the literature on non-Western viewpoints and the contemporary significance of celestial gazing in religious rituals. The results promote discussion on how modern religious communities might incorporate astronomical knowledge into their beliefs and advance our understanding of the relationship between science and spirituality. Finally, this study promotes more interdisciplinary research and highlights the timeless importance of cosmic gazing in forming human spirituality.

Abstract

This study uses sophisticated textural and fractal studies to examine the compositional and structural properties of the planetary nebula NGC 7027 located around 3,000 light-years away in the Milky Way. Metrics like contrast, dissimilarity, homogeneity, energy, and correlation were methodically assessed across several photos using Gray-Level Co-occurrence Matrix (GLCM) texture analysis, exposing a variety of interior textures. Complex and irregular features inside the nebula are indicated by high contrast (159.064), dissimilarity (6.664), and low homogeneity (0.203) values in specific places. Fractal dimension analysis that produces values near -2 points to complex, self-similar patterns connected to evolving nebulae. Furthermore, wavelet transform analysis provides information on temperature and density fluctuations across NGC 7027 by capturing multi-scale features. Chemical composition analysis further elucidates the nebula's ionization state, with observed [N II]/Hα and [O III]/Hβ ratios of 0.55 and 2.00, respectively, aligning with standard planetary nebula profiles. These ratios imply moderate ionization and highlight the nebula’s typical elemental abundances. Radial distribution of oxygen and nitrogen further supports this compositional profile, providing evidence of nucleosynthetic processes in the progenitor star. The findings underscore a strong correlation between NGC 7027’s structural complexity and chemical composition, contributing to a deeper understanding of planetary nebula evolution. This integrative approach of texture, fractal, and chemical analyses presents a comprehensive model for studying nebular morphology and evolution.

Abstract

This study investigates the limits on graviton mass using a convergence-based approach within the framework of gravitational physics. By employing theoretical models and computational simulations, we derive a graviton mass limit that is then compared with existing constraints from astrophysical observations and quantum field theories. The findings suggest that the mass of the graviton, although typically assumed to be negligible, can be constrained through gravitational wave dynamics and the interactions of massive bodies in the universe. The results highlight the potential for significant implications in our understanding of gravitational interactions and encourage further interdisciplinary research to explore the nature of gravity at both cosmological and quantum scales. These insights may pave the way for future investigations in gravitational wave astronomy, contributing to our understanding of fundamental forces in the universe.

Abstract

The objective of this research is to assess the impact of PGPR, Trichocompost, and MOL on the growth and quality of production, as well as the incidence of disease-causing microorganisms in tomato plants. This study will be conducted by comparing the use of beneficial organic microorganisms namely PGPR, Trichocompost, and MOL with inorganic farming systems that utilize synthetic fertilizers and manure as sources of nutrition for tomato plants. The research method employed a randomized block design consisting of three treatments as follows: Treatment A involved a combination of PGPR, Trichocompost, and MOL; Treatment B utilized inorganic fertilizers N, P, K along with foliar fertilizers Gandasil D and B; Treatment C consisted of chicken manure. Each treatment was replicated five times, with 50 plants per plot, resulting in a total of 750 plants for observation. The results indicated that the application of PGPR, Trichocompost, and MOL positively influenced the average flowering time, the average weight of 50 fruits, and the duration until fruit decay during the growth, development, and production phases of tomato plants. Furthermore, the use of PGPR, Trichocompost, and MOL effectively reduced the incidence of the fungal pathogen P. palmivora on leaves, the bacterial disease Erwinia sp. on leaves, and the fungal disease P. palmivora on fruit stems.

Abstract

This study investigates the recovery of dynamics of coronal dimmings across solar activity phase. The impact of plasma density, magnetic field evolution, and temperature distributions on the formation of core and secondary dimming regions in solar and astrophysical plasma environments. Using advanced simulation techniques, we modeled the evolution of plasma density and temperature, revealing significant temperature gradients and distinct density profiles.. The results show a marked decrease in plasma density at the core regions, surrounded by secondary dimming zones, consistent with observed phenomena in solar flares and coronal mass ejections (CMEs). Thermal conduction plays a crucial role in maintaining high temperatures at the core, while radiative cooling is prominent in the outer plasma regions, contributing to the cooling and dimming effects. The study also highlights the importance of magnetic flux tubes in shaping these plasma structures, with the symmetry of the density and temperature profiles supporting the confinement of these structures. These findings contribute to a better understanding of the physical processes governing plasma behavior in astrophysical contexts such as solar flares, stellar atmospheres, and galaxy clusters. Additionally, our results emphasize the need for further multi-dimensional simulations and empirical observations to validate and expand upon these findings, ultimately providing insights into space weather phenomena and other plasma-related processes in the universe. The study's findings have potential implications for space weather forecasting, stellar physics, and plasma dynamics in various astrophysical systems.

Abstract

Studies have shown significant impairments in cognitive functions in patients with major depressive disorder. This study aims to measure the loss of ability in sub-parameters of cognitive functions that occurs with changes in the severity of depression, using objective methods. In the study, the application of the computer-based neuropsychological test MOXO d-CPT to patients diagnosed with depression and the relationship between the sub-parameters obtained from this test, such as attention, timing, impulsivity, and hyperactivity, and the stage and severity of depression were examined. The study included 225 adult participants aged 18-65, who were admitted to a psychiatric clinic between 2022 and 2024 and diagnosed with Major Depression according to DSM-V diagnostic criteria. Beck Depression Inventory was administered to each participant, the MOXO d-CPT Performance Test was conducted, and a socio-demographic data form was filled out. The aim of the study is to reveal the correlation between depression severity and cognitive impairments and to provide a detailed characterization of impairments in the subcomponents of executive functions. The effects of this study on cognitive processes in relation to depression severity are expected to contribute to the literature by revealing impairments in attention, timing, impulsivity, and hyperactivity parameters at different stages of depression with objective data.

Abstract

This work investigates the use of sophisticated image analysis methods to differentiate between benign and cancerous blood cells directed on different phases of pro-B and pre-B lymphoblast growth. Binary image processing, segmentation, and masking techniques were used for 500 blood cell pictures. One hundred eighty (180) were determined to be benign and 320 to be malignant, with considerable morphological differences such as alterations in cytoplasmic ratios and aberrant nuclear structure. With 95% accuracy, these characteristics are made between benign and malignant cells to distinguish. Significant morphological variations, including anomalies in the atom form and changes in the cytoplasmic ratios, were detected, and they could extricate between malignant and benign cells with 95% accuracy. More features could be extracted from the images based on segmentation, especially when identifying cancerous cells early in their development. These results imply that automated techniques can be invaluable in helping pathologists identify hematopoietic malignancies such as acute lymphoblastic leukemia (ALL) at an early stage. Better therapy results could result from increased diagnostic speed and accuracy brought about by this automation. Further study is necessary to improve the generalizability of these systems across datasets.

Abstract

The primary aim of the present study is to evaluate the effects of hybridization ratio, fiber orientation, and mass fraction on the fiber/matrix bond properties of hybrid Gongronema latifolium stem/S-glass fiber reinforced epoxy composites. Gongronema latifolium plant stem fibers were collected from Anambra State, Nigeria, with leaves removed manually. Sodium hydroxide (2%) and epoxy resin (Grade-3554A) were used, while S-Glass was sourced locally. The fibers were extracted using a water retting method, treated with NaOH at 40-60°C for 4 hours, and dried at 70°C. For composite fabrication, fibers were aligned unidirectionally and mixed with resin and S-glass in a 250×100×5 mm mold. The hybridization ratio of S-Glass to natural fiber was fixed at 2.2 for Level 1 and 2.8 for Level 2. The mass fraction levels were at 21.24% for level one and 34.22% for level two. Fiber orientation of Level 1 was 45° while that of Level 2 was 90°. Mechanical characteristics were evaluated to ASTM D5651-21 for fiber-matrix bond strength and then analyzed using Statistical Package for Social Sciences (SPSS) and Microsoft Excel. Three models were developed, with the first model considering hybridization ratio, the second incorporating fiber orientation, and the third including mass fraction. The results show that the hybridization ratio is the most significant predictor of bond strength, with fiber orientation and mass fraction also contributing positively to the overall model. Models’ R-square values indicated how well the proposed models fitted the data: Model 1 = 0.747; Model 2 = 0.956; Model 3 = 0.980. Two unique solutions were examined further at fiber/matrix bond strength value of 0.32716MPa and value of 0.18070MPa, with a mean value of 0.25393 MPa and standard deviation value of 0.10356 MPa. The study reveals the impact of these factors on enhancing the bond strength of the composite material. The research has important and real-world applications for industries including construction, automotive, aerospace, and others where stiffer and more resistant composites are required. Future studies could be directed to investigate other variables and environmental factors that may influence performance of these hybrid composites to improve on their applications.

Abstract

The increasing proliferation of space debris from 1960 to 2021 poses significant environmental challenges for space operations. This study aims to analyze the historical trends in space debris creation, focusing on the rise of payloads and rocket debris, and assess their implications for space sustainability. Utilizing data from various space agencies and surveillance networks, we examined the growth patterns of different object types, including debris, payloads, rocket bodies, and others. The analysis revealed a sharp increase in payload deployment since 2000, driven by the rise of satellite-based technologies and the commercialization of space. Similarly, rocket debris has also seen an uptick, though at a slower rate. Debris objects, which account for the largest share, pose significant risks due to their potential to cause collisions and further fragmentation. These trends highlight the urgency of implementing effective debris mitigation strategies to prevent the Kessler Syndrome a cascade of collisions that could render certain orbits unusable. Key mitigation strategies discussed include Active Debris Removal (ADR), end-of-life disposal plans, improved space traffic management, and design-for-demise techniques. The study underscores the need for international cooperation and the adoption of innovative technologies to ensure the sustainable use of space. The findings provide valuable insights for policymakers and stakeholders in developing comprehensive frameworks for space environmental management.
