Novel Photo/Thermal-Electric and Fission-Electric Power Systems

Anatoly Blanovsky — 2025-07-03

Current green energy programs are incomplete without the long-term solution to the nuclear waste problem. In particular, spent fuel and depleted uranium (DU) that could be a major source of nuclear energy and isotopes are now being managed as waste. To integrate electrical-in-nature nuclear energy into green grids, a thermo-electric gas cooled water moderated small modular reactor (SMR) with a fission-electric (FE) corecan be used. Also,only about half of the solar radiation makes it to the Earth surface; the rest is either absorbed or reflected by clouds, and the atmosphere. A hybrid blackbody-cavity photoelectric (PE), PVand thermal modules are proposed. In the PV, PE/thermalcells, spacing between the photovoltaic (PV) mirror anode, in-planegate and cathode allows to greatly improve theirefficiencies, while also taking advantage of low-cost thermal storage.

Exploring Norbornadiene/Quadricyclane Structures for Possible Alzheimer’s Disease Detection

Ružica Marković — 2025-07-11

Developing efficient and selective biomarkers for amyloid plaques, a hallmark of Alzheimer’s disease, is a crucial step to wardimproving detection methods and potentially preventing the disease. In this study, we explore fluorescent photoswitches based on a norbornadiene (NBD) system combined with pyrene as po tential biomarker candidates. Specifically, NBD-1PY and NBD 2PY were selected, each featuring different pyrene substitution patterns. Their UV-Vis absorption spectra were computed using time-dependent density functional theory (TDDFT) across various solvent systems. Our findings indicate that the calculated spec tra in toluene closely match experimental results. Additionally, minimal spectral shifts were observed upon transitioning to sol vents more suitable for biological applications. The energy differ ences between the photoswitchable NBD and quadricyclane (QC) forms remained largely unaffected by solvent variations. These results suggest that both NBD-1PY and NBD-2PY exhibit promis ing properties for further investigation as potential biomarkers for Alzheimer’s disease detection.

Evaluation of the Protective Effects of Cinnamon on Liver and Kidney Function in Rabbits Exposed to Paracetamol Toxicity

Fayrouz. A. Khaled — 2025-07-15

This study aimed to evaluate the hepatoprotective and nephroprotective effects of cinnamon against paracetamol-induced toxicity in male rabbits. Liver and kidney functions were assessed by measuring serum biomarkers including aspartate aminotransferase (AST), alanine aminotransferase (ALT), total protein (TP), albumin (ALB), gamma-glutamyl transferase (GGT), creatinine, and urea. Paracetamol administration significantly elevated AST (48.34 ± 0.797 U/L), ALT (45.29 ± 2.073 U/L), GGT (7.90 ± 0.248 U/L), creatinine (1.00 ± 0.094 g/dL), and urea (44.76 ± 1.754 mg/dL), while reducing albumin levels (3.61 ± 0.121 mg/dL), indicating marked hepatic and renal dysfunction (p < 0.05). Conversely, cinnamon significantly reduced elevated liver enzymes and normalized kidney biomarkers, demonstrating a protective effect. Notably, the co-administration of cinnamon with paracetamol led to partial restoration of AST (39.50 ± 1.500 U/L), ALT (39.46 ± 1.402 U/L), GGT (6.80 ± 0.060 U/L), creatinine (0.76 ± 0.052 g/dL), and urea (40.48 ± 0.594 mg/dL), suggesting mitigation of paracetamol-induced damage. These effects are likely mediated by cinnamon’s bioactive constituents such as cinnamaldehyde and eugenol, which possess strong antioxidant and anti-inflammatory properties. The findings suggest that cinnamon supplementation may offer therapeutic benefits in preventing drug-induced hepatorenal injury.

Is Nuclear Power an Environmentally Friendly Energy Source? Evidence from The United States

Kagarura Willy Rwamparagi — 2025-07-26

We empirically investigate environmental sustainability of nuclear power by analyzing long-term trends in nuclear electricity production in the United States. Utilizing quarterly time-series data from the World Bank spanning 1990 to 2024, we adopt an Autoregressive Integrated Moving Average (ARIMA) modeling framework to analyze and forecast Electricity production from nuclear sources (% of total), the dependent variable. The model incorporates autoregressive (AR) and moving average (MA) components as independent variables. Estimation via Conditional Least Squares (CLS) reveals a statistically significant negative coefficient for MA(4) (-0.964), indicating a strong corrective response to shocks occurring four quarters earlier. AR(1) coefficient of 0.838 reflects a high degree of persistence, suggesting that current production levels are heavily influenced by past values. The model demonstrates strong explanatory power with an adjusted R-squared of 0.7638. Diagnostic tests confirm the robustness of the model, indicating covariance stationarity, invertibility, and absence of serial correlation. Projections indicate a gradual decline in the share of nuclear power in electricity generation, from 18.6% in 2025 to 18.2% by 2045. Although nuclear power is often lauded for its low greenhouse gas emissions, our findings challenge its classification as environmentally friendly, citing enduring concerns over radioactive waste management, accident risk, and broader ecological impacts. We conclude that the long-term sustainability of nuclear power as a green energy source is questionable and urge policymakers to carefully weigh its environmental trade-offs while prioritizing investment in cleaner, safer, and more sustainable renewable energy alternatives.

The Paradox of Oil Abundance and Fuel Scarcity in Nigeria: An Empirical Investigation

Kagarura Willy Rwamparagi — 2025-07-26

We empirically investigate the paradox of oil abundance and fuel scarcity in Nigeria, a nation that ranks among the world’s leading oil producers. Despite its vast hydrocarbon reserves, Nigeria faces chronic fuel shortages, raising fundamental questions about efficiency and sustainability of its energy consumption patterns. Using quarterly time-series data from the World Bank spanning 1990 to 2024, we apply Autoregressive Integrated Moving Average (ARIMA) modeling approach to analyze and forecast fossil fuel energy consumption (% of total), the study’s dependent variable. Autoregressive and moving average components are the independent variables. Model estimation via conditional least squares (CLS) reveals a statistically significant negative coefficient for MA(4) at -0.999984, suggesting a near-complete dampening effect of past shocks in the fourth lag period. AR(1) coefficient of 0.870696 indicates that approximately 87% of the current consumption levels are explained by the immediate past, underscoring a high degree of persistence in fossil fuel usage. Diagnostic checks confirm robustness of the model, exhibiting covariance stationarity, invertibility, and absence of serial correlation. Forecasts from 2025 to 2050 show a sustained increase in fossil fuel energy consumption, projected to rise from 55.7% in 2025 to 63.2% by 2050. Our findings highlight structural inefficiencies and policy disconnects in Nigeria’s energy sector. We recommend urgent reforms in energy governance, enhanced domestic refining capacity, and a phased transition toward sustainable energy sources to resolve the paradox of abundance amidst scarcity.

General Theory of Black Holes

Stuart Edward Boehmer — 2025-08-05

We discuss corrections to the mainstream theory of black holes in general relativity. We discuss the Schwarzschild point-mass and extended-mass solutions of the Einstein Field Equations, concluding that many of the features traditionally associated with black hole theory are absurd and incorrect. The picture of a point singularity surrounded by a surface singularity at the Schwarzschild radius does not hold water. As an afterthought, we suggest how to solve the Kerr problem (rotating black hole): by numerical methods/machine computation.

Electrons are Simply Beam Crossings

Paul Schroeder — 2025-08-05

Much of nuclear theory, testing and examination have to do with electrons. Are they particles, probably not, having no mass. The nucleus and other major particles such as the proton and the neutron have mass. So, what are electrons?

Transition of Valence Electron to the Conduction Band in Silicon

Ravi Kumar Chanana — 2025-08-02

This short communication presents the phenomenon of transition of a valence electron to the conduction band edge in Silicon as analogous to a ball of mass m falling from height h to the ground. The universal mass-energy equivalence relation is followed in this phenomenon due to conservation of energy for the constant mechanical energy with time. The relation is also pointed to be a common feature for Einstein’s theory of relativity and Newton’s law of gravitation. Errors in electron effective masses in Silicon and Silicon dioxide in an earlier publication on drifting electrons in materials is discussed and corrected.

Improvement of Multi-criteria Evaluation Tools by AHP-ELECTRE II Hybridization; Application to Drilling

Nabonswendé Macaire Ouedraogo — 2025-08-05

Elimination and Reality Choices (ELECTRE II) and Hierarchical Decision Process Analysis (HDPA) methods are widely used in decision support. Although they are effective in many cases, they are not without their limitations. The AHP method is sometimes considered to be compensatory. As for the ELECTRE II method, it lacks rigorous tools for setting the weights of the decision criteria. To overcome these limitations, we have developed a hybrid method, AHP-ELECTRE II, which combines these two approaches. This AHP-ELECTRE II hybrid combines the advantages of both methods. In this way, we have been able to put in place a procedure that allows criteria to be weighted appropriately using the technique of binary comparison between criteria in accordance with the requirements of the AHP method. This comparison is made by the decision-maker, enabling him to determine the relative weights of the criteria objectively. We then used the weights of the criteria obtained to aggregate performance using the ELECTRE II method. This enabled us to deal with the interactions between the criteria and to rank the alternatives according to how well they met the criteria defined. In our study, we applied this hybrid method to didactic problems, which enabled us to obtain satisfactory results by taking better account of the decision-maker's preferences. We used it to evaluate areas suitable for drilling, simultaneously taking into account indicators of accessibility, potential and exploitable water.The advantage of this hybrid approach is that it combines the analytical rigour of AHP with ELECTRE II's ability to handle interactions between criteria, providing a more complete method that is suited to complex multi-criteria decision support problems.

Maxwell Electromagnetism Derived From (Coulomb’ Law + Velocity), Spin-Electromagnetism Derived From (Coulomb Law + Spin), Gravito-Electromagnetism Derived From (Newton’s Law + Velocity), Spin-Gravito-Electromagnetism Derived From (Newton’s Law + Spin) --- Duality, Symmetry, Spin-Force, and Unification of Above Four Forces

Hui Peng — 2025-08-16

The Universal Mathematical Field Theory (UMFT) is established, which states that the combination of inverse square laws and either a vector field or an axial vector field create the curl of the vector/axial vector field. Utilizing UMFT, we mathematically: (1) derive the Maxwell electromagnetics (Maxwell-EM) and the Lorentz force from Coulomb’s law and the velocity of an electric source; (2) establish Maxwell-type gravity (Gravito EM) and Lorentz-type gravitational force from Newton’s law and the velocity of a gravitational source; (3) establish Spin-Electromagnetics (Spin-EM or Spintronics) from the Coulomb’s law and the spin of the electric source; (4) establish Spin-gravity (Spin-gravity) from the Newton’s law and the spin of the mass (such as neutron); (5) predicate the spin related Lorentz-type force. The so-derived Maxwell-EM justifies UMFT and shows that the experiments-based Maxwell equations have mathematical origin. UMFT shows that mathematical identities lead to physical dualities, such as the duality between Maxwell-EM, Gravito-EM, Spin-EM and Spin gravity. Therefore, the well-known concepts, effects and phenomena of Maxwell-EM may be directly converted to that of gravity and Spin. The Gravito-EM can be quantized, along the line of quantizing Maxwell-EM, and unified with Maxwell-EM force. Spin-EM predicts several new effects, including the Spin-Lorentz-type force and Lagrangian-Lorentz-type force. If experimentally confirmed, the Spin-related force may be the NEW FORCEs. Spin-EM can be utilized to describe the interaction between protons, while Spin-gravity can be utilized to describe the interaction between neutrons. The Maxwell-EM, Gravito-EM, Spin-EM, and Spin-gravity are all derived from UMFT and thus: (1) they all have the same symmetry, such as the U(1) symmetry of Maxwell-EM; (2) they all can be quantized in the same way as QED; and (3) can be unified in the frame of UMFT.

Duong M Duc — 2025-08-30

The present study aimed to investigate the current Oral Health Related Quality of Life (OHRQoL) among older adults and to explore any correlations between dental caries and OHRQoL in Southern Vietnam. A community-based, cross-sectional study was conducted was conducted among 2,700 elderly respondents (aged 60 years or older) using a cluster sampling design. A face-to-face questionnaire survey and a dental examination were used to evaluate the prevalence of dental caries. Further, the Vietnamese version of OHIP-14 (OHIP-14VN) was used to measure OHRQoL of older adults. The percentage of older adults with dental caries was 32.3%. Results show that older adults with dental caries had significantly higher physical pain and physical disability than those without dental caries. In conclusion, dental caries is a common disease that affects the quality of life among older people in Southern Vietnam. The current study suggested that dental caries should be a priority in daily and regular healthcare under a health promotion program in Vietnam.

Digging into the Tradition of Traditional Medicine - Past, Present and the Future

Md. Abdur Rahim — 2025-08-27

The Indian subcontinent as a whole, including Bangladesh, has a rich tradition of medical systems such as Ayurveda and Unani. Although these practices thrived and flourished for centuries, they were suppressed during the colonial era and reduced to the status of folk medicine. Now, perhaps before it is too late, we must focus on rediscovering this valuable medical heritage. As knowledge systems that pioneered a holistic and personalized approach to healthcare, both Ayurveda and Unani have the potential to remain innovative, dynamic, and highly valued in the ongoing evolution of integrative medicine.
