This paper seeks to design a system for monitoring the compliance of external examination centers to set rules and regulations governing the conduct of an external offline examination. The system is designed to check impersonation of examinees, aiding and abetting by teachers and other proctors, importing and submitting answer scripts written outside the approved examination halls and finally monitoring the script submission process to prevent swapping of answer booklets after completion of the examination. The proposed system consist of biometric authentication system, automated attendance system, Closed-Circuit Television (CCTV) cameras for video recording, a script submission system (SSS), a drop box for temporal storage of scripts and human monitors to analyse the recorded videos at monitoring center of the examination board. The system is designed to work even in remote areas with unstable internet as is the case with most examination centers in rural areas in Nigeria. When implemented the system will help check illegal activities in miracle examination centers and reduce examination malpractices by both examinees and proctors drastically.

This experiment was conducted in 2022 and repeated during 2023 farming season at the Teaching and Research Farm of Delta State University, Abraka to assess the response of selected varieties of groundnut to different rates of cow dung in Abraka, Delta State. It was a 5 x 2 factorial experiment carried out in randomized complete block design with three replications. The rates of cow dung in tha-1 were 0, 5, 10, 15, and 20, while the varieties were Samnut-21 and Samnut-22. After analysis of variances and means separation with Duncan Multiple Range Test (DMRT) of the data collected on yield indices of groundnut, the results indicated that Samnut-21 was outstanding in all the parameters assessed. Manure application rate of 20tha-1 gave the highest values with respect to yield of groundnut in Abraka ecology. It was therefore recommended that 20tha-1 of cow dung be applied to Samnut-21 for increased yield of groundnut in Abraka, Delta State, Nigeria.

Recently, the area of distribution theory has been receiving increased interest in generating or defining new classes of continuous probability distributions by way of extending the existing distributions. The new generated distribution is expected to be more flexible and have wider acceptability in modeling and predicting real world data sets. In this research, we proposed and study an extension of Ikum distribution using Zubai G- Family (2018) of distribution called Z-Ikum distribution. Expression of some basic structural properties of the new distribution such as cdf, pdf, quantile functions, moments, moment generating function, characteristics function and order statistics was derived. Survival function, hazard rate function, commutative hazard rate function and reversed hazard rate function was also discussed. Plots of the hazard rate function showincrease, decrease and bathtub shapes.Estimation of the proposed distribution parameters was carried out using MLE method. Performance of the parameter estimation was also evaluated via simulation studies. Result of the simulation studies indicates that our estimator is consistent. Three life data sets were used to evaluate the performance of our proposed distribution over some existing distributions. Result of the empherical study revealed that our proposed distribution performwell in modeling real life data than the competing distributions.

Consumption of alcoholic herbal products from beverages or medicinal drinks contaminated with heavy metals can cause serious consequences on human health. This is a major concern for traditional and herbal medicine. The present study was carried out to analyze and quantify the levels of seven potentially toxic heavy metals namely Magnesium, lead, cadmium, copper, iron, chromium and nickel in Action Bitter alcoholic herbal bitter. Twenty one ACTION BITTER alcoholic bitter samples were previously pretreated and homogenized were digested and analyzed to obtain a concentration of Cadmium (Cd), Chromium (Cr),Copper (Cu), Iron (Fe), Magnesium (Mg), Nickel (Ni) and lead (Pb) using atomic absorption spectrophotometer equipped with graphite tube atomizer. The concentration obtained are Cadmium (0.017 mg/l),Chromium (0.061 mg/l),Copper (0.056 mg/l), Iron (0.223 mg/l), Magnesium (1.118 mg/l), Nickel (0.112 mg/l) and lead (-0.073 mg/l). The analysis of heavy metals can be useful to evaluate the dosage of herbal drinks prepared from these plants. Therefore, it is of great importance to establish universal standards and quality requirements for hazardous elements in herbal drinks so that this natural resource can continue and expand further, to benefit health globally.

Tuberculosis is a common, and in many cases lethal, infectious disease caused by various strains of mycobacteria. Successes in treatment of tuberculosis lead to reduction in transmission, complications, and mortality among patients. The outbreak of COVID-19 drew the attention of governments and healthcare practitioners. This study considers the effect of COVID-19 on Tuberculosis treatment. Data were sourced from Taraba and Adamawa States in North-east Nigeria. A total of 8820 patients’, records were used, with 3001 from Adamawa State and 5819 from Taraba State which involved TB patients’ records. At the bivariate level, the Pearson Chi-square test was employed to measure the association between the treatment outcome and the independent variables (local government area, treatment facility ownership, treatment regimen, patients’ supported, disease site, gender, HIV status and year of treatment). Thereafter multinomial Poisson regression analysis was performed on all statistically significant variables identified at the bivariate analysis. Decisions were taken based on p-value and odds ratios. The results of this study shows that the overall treatment success and cure rate across the States was on the average, 92.7% and 49.8% respectively. The highest treatment success rate of 94.5% was achieved in year 2021, while the year 2020 witnessed the highest cure rate of 53.5%. The overall cure rate of 49.8% is below the WHO recommendation. This study recommends that the non-pharmaceutical protocols to curtail the spread of COVID-19 should be strengthened in order to curtail TB spread, and that all TB patients should be tested for HIV.

Mining activities in the Iullumeden (Sokoto) basin is often heard of due to its prominence in artisanal mode of ransacking the Earth in search of minerals and metal of high economic values. The unabated demand in the growing post-industrial era have decimated any health impact that could be borne by the inhabitants of the mining communities. Dange-Shuni is an enclave of this basin that was covered in a bid to determine the gross alpha and beta radioactivity in domestic water in and around mining points. Water samples were collected and analyzed via Hidex 300 SL system of Liquid Scintillation Counting from a systematic sampling of fifteen mining points. The results indicate that both the gross alpha and beta radioactivity concentrations were in elevation with about 80% and 85% above the global limits of 0.5 and 1.0 . The results are good reasons to work hard in order to bring dose of radioactivity exposure to the inhabitants to as low as reasonably achievable (ALARA) being a mandate of WHO.

Respiratory syncytial virus (RSV), also known as a human respiratory syncytial virus (hRSV) and human orthopneumovirus, is a common, transmittable virus that roots respiratory tract diseases. It is a negative-sense, single-stranded Ribonucleic acid (RNA) virus. It gets its name from syncytia, which are huge cells that form when infected cells merge. In this paper fractional order model of the respiratory syncytial virus (RSV) virus will be developed. The Caputo fractional derivative operator of the order will be used to generate the model scheme of non-integer differential equations. To calculate an estimated solution of the system of nonlinear fractional differential equations, the Laplace-Adomian Decomposition Method was used. Infinite series was produced as solutions to fractional differential equations. The model's proposed series solution converges quickly to its precise value. The obtained results are compared to the standard case.

Papaya (Carica papaya Linn) is a popular fruit grown in the tropical and subtropical parts of the world, also known as "pawpaw". The fruit is consumed when ripe and also processed. The many benefits of papaya are owed due to the high content of Vitamin A, B and C, and minerals. This study aimed at determining the concentration of vitamin C in two species of the fruits as a function of the ripening periods, using the redox titration method indicated that the concentration of vitamin C decreased from 98 mg/kg to 70 mg/kg in Samba papaya and from 96 mg/kg to 68 mg/kg in the Hortus gold papaya with ripening period. Samba papaya is recommended for vitamin C enhancement at the early ripening stage. Calcium, magnesium and potassium concentrations determined using atomic absorption spectrophotometry decreased in concentration with storage day. Domestic and industry supply of vitamin C and essential minerals is key to health need to be obtained from fruits at the optimum stage.
木瓜（Carica papaya Linn）是一种生长在世界热带和亚热带地区的常见水果，也被称为 "pawpaw"。这种水果成熟后即可食用，也可进行加工。木瓜的诸多益处归功于其富含的维生素 A、B、C 和矿物质。这项研究旨在确定两种水果中维生素 C 的浓度与成熟期的关系，使用氧化还原滴定法表明，随着成熟期的延长，桑巴木瓜中维生素 C 的浓度从 98 毫克/千克降至 70 毫克/千克，Hortus 金木瓜中维生素 C 的浓度从 96 毫克/千克降至 68 毫克/千克。 建议桑巴木瓜在早熟阶段提高维生素 C 的含量。用原子吸收分光光度法测定的钙、镁和钾的浓度随着贮藏天数的增加而降低。国内和工业供应的维生素 C 和必需矿物质是健康的关键，需要在最佳阶段从水果中获取。

The fruit is consumed when ripe and also processed. The many benefits of papaya are owed due to the high content of Vitamin A, B and C, and minerals. This study aimed at determining the concentration of vitamin C in two species of the fruits as a function of the ripening periods, using the redox titration method indicated that the concentration of vitamin C decreased from 98 mg/kg to 70 mg/kg in Samba papaya and from 96 mg/kg to 68 mg/kg in the Hortus gold papaya with ripening period. Samba papaya is recommended for vitamin C enhancement at the early ripening stage.
