The study of gross radioactivity and its associated hazard risks in potable water is crucial to the health and well-being of the populace of the study area. Thus, radiological hazard indices such as annual effective dose, excess lifetime cancer risk, lifetime hereditary effect, and lifetime fatality cancer risk due to gross alpha and beta radiation from fifteen samples of borehole water have been evaluated. The mean values obtained from the analyses are 2531.48E–5 mSvy–1 & 5637.92E–5 for AED, 12.18E–5 & 23.26E–5 for ELCR, 443.01E–5 & 845.69E–5 for LHE and 12.18E–5 & 23.26E–5 for LFCR, respectively. By comparison, all the mean values obtained from this study are below the recommended limits set by UNSCEAR. Thus, the study indicates that the groundwater in the study area is radiologically safe for drinking purposes as the radiation dose level is very low. However, it is recommended that the study be further expanded to include all sources of potable water in the study area. This study aimed to provide baseline radiological survey of potable water for the study area.

This comprehensive review delves into advancements in air quality monitoring for atmospheric lead detection, focusing on the utilization of wireless sensor networks (WSNs). The review traces the evolution of monitoring techniques from traditional methods to advanced technologies, highlighting the transformative role of WSNs in environmental monitoring. WSNs offer advantages such as real-time data acquisition and spatial coverage, enabling continuous and widespread monitoring of lead concentrations in the atmosphere. Technological enhancements in WSNs for lead detection, including sensor technologies and integration with IoT and big data analytics, are examined. The review underscores the importance of sensor accuracy, calibration, and environmental impacts, alongside economic and regulatory challenges in deploying WSN-based monitoring systems. Furthermore, case studies demonstrate the successful deployment of WSNs for lead monitoring, showcasing their effectiveness in local and regional air quality management. Comparative analyses with traditional methods underscore the advantages of WSNs in terms of accuracy, reliability, and scalability. The framework outlines the approach for conducting a literature review, data collection, case study selection, interviews, comparative analysis, synthesis, and future directions. Recommendations for future research emphasize the need for advancements in sensor technology and network systems, aiming to address gaps and improve the efficacy of air quality monitoring initiatives. The implications of WSNbased lead monitoring for stakeholders, particularly in African countries like Nigeria, are discussed, highlighting the potential to address air quality challenges and promote sustainable development.

Analysis shows that there is existence of disease-free whenever the threshold quantity R0 is less than unity i.e. R0 >1 , and otherwise epidemic when R0 >1 . Utilizing mathematical techniques and computational simulations, we explore the stability of these equilibrium points under varying conditions and treatment scenarios.

This study investigated the effect of granulated plantain peels on the biogas yield from cattle dung.

Results showed a 168% increase in biogas produced when cattle dung was pretreated. The flammability test showed that production started on the first day after retention for the substrate pretreated and that an appreciable amount of methane content was produced only on the third to fourth day. In contrast, in the control, production started on the third day, and appreciable methane was observed on the fourth to fifth day. The compression test showed that biogas could be compressed with minimal changes in temperature as the temperature observed amounted to only a 0.19 ℃ rise per bar increase in pressure. The biogas compression experiment gave an accumulated mass of 214 g at 6.34 bar compared to 1000 g at 6 bar for standard LPG refilling.

This study assessed the direct cost of hypertensive health care; determined the presence of catastrophic health expenditure (CHE) or otherwise and its associates/predictors (when present) among hypertensive patients accessing care in a semiurban tertiary hospital in South-South Nigeria, using a cross- sectional study design. Three hundred and twenty respondents were selected using a systematic random sampling technique. Data on sociodemographic indices, monthly cost of accessing hypertensive care, cost of living and sundry matters were collected using a pre- tested interviewer-administered questionnaire and analyzed using IBM® SPSS version 23. The mean age of respondents was 54.8 years (± 16.5), and 43.4% was at least 60 years old. The majority Of the respondents (55.9%), were females. The average monthly cost of managing hypertension was ₦36,814; with the highest amount spent on laboratory investigations and drugs. Nine out of ten respondents were exposed to CHE. Patients’ educational status and presence of co-morbidities were associated with CHE. However being self-employed was the only predictor of CHE, with self-employed respondents having 5 times more odds of CHE than the unemployed. The study showed that the vast majority of hypertensives paying out-of -pocket suffer a substantial financial burden and are exposed to financial catastrophe. Governments at all levels need to formulate polices that will lead to increase in the access to affordable and timely quality health care for hypertensive patients in order to reduce the huge financial burden currently incurred by them.

Bioethanol was produced from sugarcane molasses using tamarind supplements at different pH and temperatures. The volatile profile of the bioethanol produced was evaluated using Gas chromatography and mass spectroscopy (GC-MS). Bioethanol was produced from sugarcane molasses hydrolyzed using tamarind pulp syrup (TPS) and distilled water (DW) at different temperatures (26-30 oC) and pH (4.5-6.5) and utilizing Saccharomyces cerevisiae for fermentation. The results showed a significant increase in reducing sugar yield, bioethanol yield/quantity, and bioethanol volatility for the bioethanol produced using TPS hydrolysis compared to those produced using DW (p<0.05). The suitable temperature and pH for the production of the maximum amount of reducing sugar and bioethanol were 28 oC and 5.5 respectively. The volatility of the bioethanol produced was highest at a temperature of 28 oC and a pH of 5.5. The density of bioethanol obtained using TPS (0.797 g/cm3) was close to the standard density of bioethanol (0.789 g/cm3). Conclusively, TPS was found to enhance bioethanol production from sugarcane molasses through fermentation. This suggests that it could serve as an alternative hydrolyzer for the production of biofuel.
