Abstract

This research investigates the demographic characteristics of patients diagnosed with Benign Prostate Hypertrophy (BPH) at the Federal Medical Centre (FMC) Azare, Bauchi State, from 2014 to 2018. BPH, characterized by the non-cancerous enlargement of the prostate gland, is recognized as the most common urological condition affecting adult males globally. The study aims to determine the number of patients diagnosed and treated with BPH, identify the most affected age group, examine the family structure most commonly associated with the condition, and assess the parity of affected patients. A descriptive survey design was adopted, utilizing anecdotal records from 423 patients diagnosed with BPH during the study period representing a full enumeration of the target population. Data were analyzed using percentages and presented in frequency distribution tables. The findings revealed that the highest number of BPH cases occurred in 2018. The most affected age group was between 50 and 80 years (44%), with patients from polygamous families comprising the majority (79%). Furthermore, 54% of patients had five or more children. Based on these results, the study recommends that health professionals intensify educational efforts targeting men at risk of BPH, focusing on its causes and prevention. Additionally, government support is urged, particularly in the provision of medical assistance such as medications for affected individuals.

Abstract

Achieving maximum customer satisfaction in the Global System for Mobile Communications (GSM) industry has become increasingly challenging due to heightened awareness of consumer rights, population growth, and economic expansion. A critical factor influencing service delivery is network congestion, which significantly impacts the Quality of Service (QoS), a key performance indicator (KPI) used to assess the efficiency of telecommunication services provided to end users. Core metrics for evaluating QoS include accessibility, voice connection quality, and retainability. While various studies have explored methods to mitigate congestion, interference remains a major constraint on the capacity of Wideband Code Division Multiple Access (WCDMA) systems, especially in regions where population density fluctuates, forming high-demand zones or "hot spots." This study investigates the application of adaptive sectorization as a strategy to reduce co-channel interference. The methodology involves modifying the number of antennas in the base station array, analyzing energy leakage between users, and examining the resulting radiation patterns for three mobile devices to measure inter-user interference. Results indicate that increasing the number of antennas narrows radiation beams and reduces off-diagonal interference levels. The findings demonstrate that adaptive sectorization consistently enhances system capacity, with particularly notable improvements in scenarios where user concentration in hot spots significantly exceeds that in surrounding areas.

Abstract

Electric vehicles (EVs) have emerged as a response to the increasing environmental impact of combustion engines and the rising demand for fossil fuels, offering a sustainable alternative to meet the growing transportation needs that underpin economic development. Ensuring the safe operation of EVs on existing road infrastructure, particularly in environments with physical speed breakers, remains a critical concern. Speed bumps are commonly used to prevent collisions due to excessive speeding; however, they often compromise driving comfort and pose safety risks when encountered unexpectedly. This study proposes a smart speed control system for electric vehicles using a fuzzy logic controller, aimed at replacing traditional speed breakers. The system operates by deploying a transmitter at the entry point of a speed-regulated road segment, which sends speed limit data to approaching vehicles equipped with a corresponding receiver. Upon receiving the signal, the vehicle's speed is automatically adjusted to the designated limit. Once the vehicle exits the speed-restricted zone, a new signal allows it to resume normal speed. Developed using MATLAB/Simulink, the fuzzy logic-based control system not only enhances road safety and driving comfort but also contributes to energy efficiency in EVs. The successful implementation of this vehicle-to-infrastructure (V2I) communication model demonstrates the feasibility of intelligent speed regulation, suggesting its integration as a standard feature in future EVs. This approach provides traffic authorities with a proactive means of managing vehicle speed without direct driver intervention.

Abstract

This study presents a comprehensive approach to the modeling, simulation, and analysis of single line-to-ground (SLG) fault detection in high-voltage power transmission systems. A dual-unit detection system was developed, integrating a MATLAB/Simulink-based simulation model with a microcontroller-based hardware unit for real-time fault identification and communication. The simulation model replicates the behavior of a 132 kV transmission line under various SLG fault conditions, while the hardware unit employs voltage and current sensors connected to an Arduino Uno and GSM module to detect faults and transmit location alerts. Experimental procedures included controlled fault injection, waveform analysis, and algorithmic fault distance estimation using zero-sequence currents and voltage dips. Simulation outcomes demonstrated high location accuracy, with error rates consistently below 0.75% across a fault distance range of 30–300 km. The system exhibited fast response times, high precision, and cost-effectiveness, indicating strong potential for deployment in power grids of developing regions. The integrated software-hardware architecture offers a scalable and efficient solution for minimizing downtime and enhancing fault response coordination in transmission networks.

Abstract

The preservation of stored grains against weevil infestations is critical for ensuring food security and minimizing post-harvest losses in Nigeria, where insect pests remain a major constraint to effective grain storage. This study evaluates the efficacy of seed extracts of Azadirachta indica in controlling Sitophilus zeamais. Seeds were extracted using five solvents—methanol, ethanol, acetone, petroleum ether, and n-hexane—and the resulting oils were tested for their effects on insect mortality, oviposition, adult emergence, grain damage, and long-term storage viability. Results indicate that ethanol extract was the most effective, inducing 100% mortality within 96 hours of exposure, followed by n-hexane (88.25%), petroleum ether (85.75%), methanol (82.25%), and acetone (76.15%). Extracts also significantly reduced oviposition and adult emergence, with complete suppression observed in ethanol-, petroleum ether-, and n-hexane-treated grains. These treatments also fully prevented grain damage and weight loss for three months, while methanol and acetone extracts allowed limited damage (9.19% and 8.18%, respectively). Germination tests showed high viability (95.25–98.25%) across all treatments, with the lowest germination recorded in petroleum ether extract (95.25%). The findings suggest that A. indica seed extracts are highly effective in managing S. zeamais infestations and represent a viable alternative to synthetic insecticides for safe and sustainable grain storage.

Abstract

This study evaluates the mechanical properties of hydraulic concrete reinforced with recycled Polyethylene Terephthalate (PET) plastic fibers, addressing both construction performance and environmental sustainability. While concrete is a widely used material for its strength and durability, the increasing production and disposal of PET waste present significant ecological challenges. Incorporating recycled PET fibers into hydraulic concrete offers a dual benefit: reducing plastic waste while potentially improving the material’s mechanical performance. Despite prior research on plastic additives in concrete, limited attention has been given to the specific mechanical behavior of hydraulic concrete reinforced with recycled PET fibers. The main objective of this research is to analyze the effect of PET fiber incorporation on compressive strength through controlled laboratory experiments. Concrete mixes with varying fiber proportions were prepared and subjected to compressive strength testing, with results compared to standard concrete performance. Beyond technical evaluation, the study also situates its findings within the framework of the Sustainable Development Goals (SDGs), highlighting PET recycling as a strategy for advancing sustainable construction and waste management. The results are expected to inform the development of more sustainable and efficient concrete formulations while contributing to broader environmental conservation efforts.
