M.Item Assessment of Electrical Energy Consumption in Some Selected Tertiary Institutions Administrative Buildings in Niger State(School of Environmental Technology, Federal University of Technology Minna. PMB 65, Minna, Niger State Nigeria., 2024-11-29) Musa Titus Dada; Akanmu Williams Paul; Jimoh Richard A; Ejiga Anthony EjigaHigh electrical energy consumption in public buildings and institutions poses a significant challenge, particularly in developing countries like Nigeria. Inadequate empirical studies on building energy use have resulted in a lack of electrical energy data, especially in tertiary institutions where bulk metering is common. This study aimed to assess the electrical energy consumption in selected administrative buildings of tertiary institutions in Niger State, with the goal of reducing electrical consumption and improving energy efficiency. Experimental data collection involved direct field measurements using a real-time Efergy wireless energy (EW4500) monitoring device. Current transformer sensors were attached to the main distribution panels of the administrative buildings at the Federal University of Technology Minna, Niger State Polytechnic Zungeru, and Niger State College of Education Minna. The objectives included evaluating electrical energy consumption, comparing total consumption across buildings, and analyzing energy consumption patterns. Results indicated that the Senate building at FUT Minna had the highest consumption rate at 2604.7 KWh/m², followed by Niger State Polytechnic Zungeru at 2579.1 KWh/m², both exceeding the global benchmarks of 128 to 130 kWh/m² set by the Chartered Institute of Building Services Engineers (CIBSE) and the Building Energy Efficiency Guideline for Nigeria (BEEGN). In contrast, COE Minna’s administrative building, with consumption levels averaging 1579.1 KWh/m², generally fell within these benchmarks. The elevated energy consumption at FUT Minna and Niger State Polytechnic Zungeru was primarily attributed to operational inefficiencies, such as the continuous operation of HVAC systems and equipment during non-essential hours, even when buildings were not fully occupied. Hourly consumption patterns revealed peak usage during early working hours, with significant seasonal variations; however, both FUT Minna and Niger State Polytechnic Zungeru exhibited high energy use during off-peak periods, reflecting poor energy management practices. To address these inefficiencies, the study recommends conducting comprehensive energy audits and installing energy-efficient appliances at FUT Minna and Niger State Polytechnic Zungeru. Additionally, implementing smart metering, occupancy sensors, and optimized HVAC controls would significantly enhance monitoring and reduce energy consumption. These measures are critical for improving energy efficiency and ensuring sustainable operations in both institutions.Item Optimizing HVAC Systems for Sustainable Lecture Rooms: Harnessing Environmental and Occupancy Data for Comfort and Energy Efficiency through Data-Driven Insights(School of Environmental Technology, Federal University of Technology Minna. PMB 65, Minna, Niger State Nigeria., 2024-11-29) Abdulwaheed Badmus; Musa Titus DadaThe escalating energy consumption in campus infrastructure, especially in lecture halls with heating, ventilation, and air conditioning (HVAC) systems, necessitates data-driven optimization strategies. This research demonstrates the integration of Internet of Things (IoT) sensors with cloud-based predictive analytics to develop intelligent lecture room policies aimed at enhancing efficiency and sustainability. A Raspberry Pi-based IoT device, equipped with a BME680 sensor for monitoring temperature, humidity, and air quality, and a passive infrared sensor for occupancy detection, was installed in a university lecture room for real-time data acquisition. Data collected was routed through MySQL for storage and Node-RED for preprocessing. Time series forecasting models, including ARIMA and Prophet, along with machine learning models like XGBoost, achieved over 90% forecast accuracy for temperature and occupancy levels, enabling proactive control of environmental conditions. The optimized HVAC scheduling, based on forecasted occupancy patterns, resulted in a 20% reduction in energy consumption over an 8-week deployment, ensuring thermal comfort by maintaining temperatures within the recommended range of 21-23°C during occupancy. Enhanced occupant comfort was also achieved by maintaining humidity levels between 40-60%, improving indoor air quality through proactive ventilation control. Key recommendations include dynamic HVAC scheduling based on occupancy forecasts, thermostat setpoint adjustments to prevent temperature peaks, and expanding IoT sensor deployments across campus facilities to generate deeper insights. This integrated IoT and predictive analytics approach enabled a sustainable and responsive built environment, providing a scalable framework for optimizing other infrastructure types such as laboratories and offices.Item Anti-trypanosomal Activity of Leaf Extracts of Andrographis paniculata in Trypanosoma brucei brucei-infected Mice(Nigerian Journal of Parasitology, 2025-03) Ismail, A; Omalu, I.C.J.; Abolarinwa, S. O; Abdullahi, M.; Adeniyi, K.A.; Ocha, I.MAfrican Animal Trypanosomiasis is a disease of major economic and public health importance, especially with the current setback in the treatment of cases using synthetic anti-trypanosomal agents. As a result, there is an urgent need to identify alternative compounds for chemotherapy. Therefore, the present study investigated the phytochemical composition, acute oral toxicity, and in vivo antitrypanosomal efficacy of crude methanol, n-hexane fraction, and ethyl acetate fraction of Andrographis paniculata (king of bitters) leaf in Trypanosoma brucei brucei-infected mice. The methanol extract was screened for the presence of secondary metabolites by using standard methods. The crude plant extract and fractions were administered orally to the parasite-infected mice at doses of 300 and 600 mgkg-1 body weight (b. wt) following standard procedures. The result was compared to Diminazine aceturate which was given at the recommended dose of 3.5 mgkg-1 b. wt subcutaneously. Phytochemical screening has revealed the presence of alkaloids, flavonoids, saponins, phenols, glycosides, steroids, tannins, and anthraquinones. Diminazine aceturate gave a 100% parasite clearance, and the mice survived throughout the study period (60.00±0.00) days. A. paniculata extract at 600 mgkg-1 b. wt was found to be effective in reducing the parasite multiplication by 43.58 % and extending the life span of the treated mice to (10.50±0.50) days compared to the untreated control, (7.45±0.55) days. Ethyl acetate fraction on the other hand was found to be more effective in reducing the parasitaemia level (61.33 % and 75.63 %) and extending the life span of the mice to (12.50±0.34) and (15.76±0.23) days for both 300 and 600 mgkg-1 b. wt doses respectively, whereas the n-hexane gave a limited trypanocidal effect of 9.89 % and 21.15 %. The results obtained in the present study suggest the ethnopharmacological usefulness of the plant and necessitate further studies on isolated active substances from this plant.Item Mathematical model and analysis of the soil-transmitted helminth infections with optimal control(Springer Science and Business Media LLC, 2024-02) Festus Abiodun Oguntolu; Olumuyiwa James Peter; Abubakar Yusuf; B. I. Omede; G. Bolarin; T. A. AyoolaSoil-transmitted helminth diseases are highly prevalent in impoverished regions and pose a significant health burden on the global population. These diseases are primarily transmitted through the contamination of soil with human faces containing parasite eggs. This study presents a novel deterministic mathematical model to comprehensively investigate the dynamics of helminth infection transmission through the soil. The mathematical model exhibits two equilibrium points: the diseases-free equilibrium point (DFE) and the endemic equilibrium point (EEP). The DFE is proven to be locally and globally asymptotically stable when the basic reproduction number is less than one, indicating the potential for disease eradication. Conversely, the EEP is locally asymptotically stable when the basic reproduction number exceeds unity, representing a persistent endemic state. To explore effective intervention strategies for controlling the spread of these infections, optimal control theory is applied. The study incorporates two time-varying control variables derived from sensitivity analysis: the rate of hygiene consciousness in the susceptible class and the rate of hygiene consciousness in the infectious class. Numerical simulations demonstrate that implementing optimal control strategies can successfully curb and mitigate soil-transmitted helminth infections. Overall, this research highlights the importance of proactive and targeted interventions, emphasizing the significance of hygiene education and awareness campaigns. By implementing optimal control measures based on the proposed strategies, the burden of soil-transmitted helminth diseases can be significantly reduced, improving public health in affected regions.Item Therapeutic Waiting Areas: A Study of Perceptions of Patients and their Companions in Hospitals(Journal of Current Trends in Nursing and Health Care, 2025-05-19) Lawal, Lateef Ademola; Makun, Charles Yakubu; Ogunbajo, Rukaiyat Adeola; Obideyi, TaiwoThe waiting area has an influence on patients and their companions and plays an important role in accessing medical services. Research suggests that hospitals are stressful environments, with high levels of uncertainty, fear, and anxiety. While the impact of healing and therapeutic features on patients’ in waiting areas of healthcare settings is known in Western cultures and contexts, there has been little or no research focused on the therapeutic features in waiting areas, particularly in Nigeria. This present study examined the perceptions of the features of therapeutic waiting areas and their effects on patients’ hospital experience, stress, and perceived relaxation. A survey questionnaire was employed to collect data from patients and their companions at two hospitals in North Central, Nigeria about their perceptions of therapeutic features in the waiting areas. The data were analysed using standard statistical methods. The results from this study demonstrated the significant importance of having well-designed waiting areas/rooms equipped with appropriate furniture in healthcare settings for the comfort of patients and carers. Additionally, views of nature, waiting areas with easy access to natural greenery, the presence of large windows, and calming and relaxing colours were identified as features that improve visual connection to nature and increased positive feelings and moods. The study, the first in a series of waiting room studies in Nigeria, provides valuable insights that can be useful for designing waiting areas in healthcare facilities. It also has the potential for fostering comfortable waiting areas for the wellbeing of patients and users in healthcare environments.Item Environmental Risks and the Effects of Noise on Residents' Quality of Life and Well-being in Nigerian Urban Residential Environment(Frontiers in Water and Environment, 2025) Akande, Oluwafemi K.; Akinbami, Ademola A.; Akeremale, Igbayemi D.; John, Ayuba B.; Haruna, Aisha G.; Oshineye, Adegbenga A.; Lawal, Lateef Ademola; Anikor, Emmanuel M.; Sola-Adebiyi, Oyeyemi P.Environmental noise pollution is becoming a major concern in cities around the world, with serious consequences for public health and quality of life. In Nigeria, increasing urbanisation and uncontrolled urban growth have exacerbated noise pollution from transportation, industrial activity, and commercial hubs. This study examined environmental risks connected with noise pollution and its impact on residents' quality of life in Nigerian cities. The study used a mixed-methods approach, integrating noise level measurements (using a sound pressure level meter), resident questionnaire surveys (n=880), and spatial analysis to determine noise hotspots in the city centre. and their relationship to household satisfaction. The findings were compared to national (50 dBA) and worldwide (55 dBA) standards by the WHO. The findings revealed that noise from places of worship and road noise were highly rated, with about 75% of respondents reporting that environmental noise has a negative influence on their quality of life. The study recommended a synergistic approach to built environment design, design quality of residential buildings, and interventions by architects and other built environment experts to combat urban environmental pollution in residential settings. The study contributes to urban policy through its recommendations for noise mitigation measures and urban design frameworks that encourage healthier living conditions.Item Users’ Perception on Visual Enhancement Features in Heritage Museums in Nigeria(Hummingbird Researich International, 2024-01) Omilola, Ilim Tayo; Lawal, Lateef AdemolaMuseums serve as links between the past and present, serving as symbolic monuments for the preservation of culture, including past and contemporary history. They are essential to the preservation and presentation of the tangible and intangible aspects of a country’s or community’s cultural heritage. Research about heritage museums has primarily focused on values of historical artefacts, but the creative and aesthetic aspects of the museum in terms of ambiance, such as lighting, spatial and interior design have been scant. This undervaluing of these aspects may lead to a decreased appreciation and understanding of artefacts, undervalued engagement, and a less than ideal visitors’ experiences. The aim of this study is to assess visitors’ perceptions of visual enhancement features on the users’ overall experiences. The study utilised a survey questionnaire methodology, gathering data from 212 participants using an online Google Forms platform. The result of the study demonstrated the importance of well-balanced lighting, carefully designed interior choices and a well-organised spatial layout in providing visitors with a visually appealing and captivating experience.Item The Role of Local Dyes in Dye-Doped Stannates and Titanates for Enhancement f Solar Energy Capture(FUDMA Journal of Sciences, 2025) Eze, C. N.Local dyes play a crucial role in enhancing solar energy capture in dye-doped stannates and titanates by acting as light-harvesting agents, boosting the efficiency of dye-sensitized solar cells (DSSCs). These dyes, when adsorbed onto the surfaces of porous semiconductor materials like TiO2, absorb incoming sunlight and then inject electrons into the semiconductor, initiating an electron transfer process that generates electricity. This process is similar to how plants capture sunlight in photosynthesis. Stannates and titanates, such as TiO2, ZnTiO3, BaSnO3 etc provide a porous surface for dye adsorption and act as the conductive material for electron transport. Their nanostructured surfaces increase the surface area available for dye adsorption, enhancing light capture.
