    Mathematical Modeling on the Transmission Dynamics of HIV and Hepatitis B (HBV) Co‐Infection in the United States
    (Wiley, 2025-06-26) F. A. Oguntolu; O. J. Peter; D. Aldila; G. B. Balogun; A. O. Ajiboye; B. I. Omede
    Human immunodeficiency virus (HIV) and hepatitis B virus (HBV) are major public health concern worldwide, contributing to significant morbidity and mortality. Managing co-infection between HIV and HBV presents additional challenges in clinical treatment and patient outcomes. In this article, we developed a comprehensive co-infection model to explore the complex transmission dynamics between HIV and HBV in the United States. Our model incorporates crucial factors such as infection through birth or migration, HBV vaccination, and the possibility of reinfection following HBV recovery. Our mathematical analysis started with the analysis of the two non-co-infection submodels, that is, for HIV-only and HBV-only models. We derived the basic reproduction number for each submodel and applied the Routh-Hurwitz criterion to assess the local stability of their respective disease-free equilibrium points. Our investigation revealed that the HIV-only submodel is globally asymptotically stable when its basic reproduction number remains below one. Conversely, the HBV-only submodel exhibits a backward bifurcation, meaning that both disease-free and endemic equilibrium states can coexist even when the reproduction number falls below one. This phenomenon complicates HBV control strategies under such conditions. However, in the absence of reinfection, the HBV-only model reaches global stability at the disease-free equilibrium whenever its reproduction number is below one. Using center manifold theory, we further demonstrated that the full HIV-HBV co-infection model also undergoes backward bifurcation. A sensitivity analysis was conducted on the basic reproduction numbers of HIV and HBV to identify critical parameters influencing the transmission dynamics of both infections. Our results indicate a positive correlation between the spread of one infection and the prevalence of the other. Additionally, we validated the model by fitting it to annual cumulative data on new HIV cases and reported acute HBV infections in the United States. Numerical simulations suggest that increasing condom use adherence, enhancing treatment coverage for both infections, and boosting HBV vaccination rates can substantially reduce the prevalence of HIV, HBV, and their co-infection.

    IoT-based Beverage Fraud Detection: A Theoretical Review
    (CUJOSTECH, 2025) AJiboye, Johnson Adegbenga; Usman, A. U.; Oyewobi, S. S.; Abdulbaki, A. O.; SAlihu, B. A.; Mamman, T. A.
    This theoretical review explores the foundational theories, frameworks, and models relevant to the design of an Artificial Intelligence (Al) and Internet of Things (IoT)-based system for detecting counterfeit and expired carbonated beverages in the Nigerian market. The growing incidence of beverage fraud, including dilution, mislabeling, and expiration concealment, necessitates the adoption of advanced detection mechanisms. This study explores the use of Bayesian Linear Regression (BLR) to analyze caffeine and CO: concentrations within established theories from food safety, sensor analytics, and machine learning. By comparing and critiquing traditional and modern approaches, the review highlights the strengths of integrated lot and Machine Learning (ML) technologies for scalable, real-time quality monitoring. The key finding from the review is that integrating lot-enabled sensors, BLR, and ML within the Fake Beverages Detection Systems (FaBEDs) framework offers a scalable, real-time, and interpretable approach for detecting counterfeit and expired carbonated beverages, particularly suitable for low-resource settings like Nigeria. This work contributes a critical perspective on how theoretical models can inform practical implementations for safeguarding public health and ensuring beverage supply chain integrity in developing economies.

    Technology Education: A Vehicle for Sustainable Youth Empowerment in Nigeria
    (SAMUTECH SERVICES LTD, 2008) Igwe, C. O.
    The technology objective of the National Policy on Education FRN (2004), centered on increasing the productive potential of the Nigerian youths thereby increasing the chances of producing better goods and services. The socio-economic development of Nigeria is strongly tied to effective implementation of technology education programme. Empowering the youths with relevant knowledge, productive skill and work habits, appear indispensable. This paper addressed technology education as a vehicle for sustainable youth empowerment. Strategies for this empowerment were discussed and recommendations made for its sustainability, among which are: organizing workshop/conferences on the “how to” and ‘benefits” of technology education, and encouraging young graduate on initial establishment of small scale trades were highlighted.

    The methods of Integrating Technology in Teaching and Learning. Teaching with Technology: Perspectives, Challenges and future Directions
    (Nova Science Publishers New York, 2019) Igwe, C. O.; Mustapha, A.
    The method used for active teaching and learning is a point of grave interest to educators and teachers. Methods of instruction in any education circumstance deliver a lively role in exciting analytical and artistic thought, improving student cooperation and guaranteeing that students observe a problem from varied viewpoints. They are planned to give scholars the chance to watch, interlace in and develop or identify expert’s procedures in circumstance. Therefore, this chapter highlighted drill and practice, dialogue, and tutorial as methods of integrating technology in teaching and learning.

    Assessment of the Metacognitive Awareness and its Implication on the Technical College Students’ Academic Achievement in Niger State
    (Journal of Information, Education, Science and Technology (JOEST), 2014) Owodunni, S. A.; Igwe, C. O.; Hassan, A. M.
    This study assessed technical students’metacognitive awareness and its implication on their academic achievement in Niger State technical colleges. The study adopted a correlation survey research design. The population of the study was 188 National Technical Certificate (NTC) 11 technical students. Three research questions and three null hypotheses, tested at 0.05 level of significance, guided the study. The instrument used for data collection were Metacognitive Awareness Inventory (MAI) and Technical Drawing Achievement Test (TDAT). The inventory was validated by experts for use in Nigeria context. The trial test for determining the coefficient of stability of the instrument was carried out using 40 students in Government Science Technical College Garki, Abuja in the Federal Capital Territory. The reliability coefficient computed for the achievements test was found to be 0.088. Mean was used to answer the research questions. Kendall’s Tau-b correlation coefficient was applied for the measurement of correlation among/between the variables of interest, while t-test statistics was employed to test the hypotheses. The study found out that male students performed better than the female students in the achievements test and MAI subscales. The study revealed among others that urban students performed better than the rural students in the achievement test and MAI subscales; there was a link among internet usage, library habits students metacognition and student’s achievement performance of highly metacognitvely aware students was better on the achievement test than low metacognitively aware students; there was no significant difference between metacognition of male and female students and between urban and rural students. Consequently, it was recommended among others that the training of students should be focused on where they need support to develop their metacognition and that internet surfing and reading library books have good impact on metacognitive awareness.
