As artificial intelligence (AI) technologies evolve, they are increasingly integrated into strategic decision-making processes across industries. This paper examines the dual role of AI in managerial practice, focusing on both the opportunities and challenges it introduces. AI systems enhance decision-making by offering predictive insights, processing large datasets in real time, reducing cognitive bias, and supporting managerial judgment. However, challenges such as algorithmic opacity, ethical concerns, over-reliance, and organizational resistance present significant barriers to effective adoption. To structure this analysis, the paper introduces a conceptual framework that views AI as a decision-support system operating across three interrelated layers: AI capabilities, the managerial interface, and the organizational context. Through a critical literature review and synthesis, the study underscores the importance of human oversight, ethical design, and leadership readiness. The conclusion offers practical recommendations for organizations aiming to leverage AI strategically while avoiding unintended consequences, particularly in volatile markets and disrupted supply chains.
ABSTRACT This study presents the physicochemical characterization of Eichhornia crassipes (water hyacinth) as a potential renewable feedstock for biofuel generation. The biomass was harvested from freshwater sources, followed by thorough cleansing to remove dirt, sediment, and attached debris. The cleaned material was chopped and ground to enhance uniformity and increase surface area, ensuring accu-rate and representative physicochemical analysis. Comprehensive proximate and ultimate analyses were conducted to evaluate its suitability for anaerobic digestion and biodiesel production via transesterification processes. The proximate analysis revealed a moisture content of 43.08%, ash con-tent of 8.00%, volatile solids of 75.50%, and lipid content of 6.24%, indicating high organic matter availability and favorable biodegradability. The pH of the biomass was measured using a calibrated pH meter in a homogenized aqueous slurry, providing insight into its chemical environment and suitability for microbial activity. Biochemical oxygen demand (BOD) and chemical oxygen demand (COD) values further confirmed the high degradable organic fraction of the biomass. The ultimate analysis showed a carbon-to-nitrogen (C/N) ratio of 25.57, which falls within the optimum range for stable anaerobic digestion. The moderate nitrogen content and significant volatile solids suggest bal-anced nutrients capable of supporting efficient microbial activity, while the relatively low ash con-tent indicates minimal inorganic interference during thermal and biological conversion. Overall, the physicochemical results, combined with detailed preparation and measurement protocols, demon-strate that Eichhornia crassipes possesses favorable chemical, elemental, and processing characteristics suitable for efficient biogas and biodiesel production, validating its potential as a sustainable ligno-cellulosic resource for integrated bioenergy systems.
ABSTRACT This study presents the design and execution of gravel packs and sand screens as a mechanical method of controlling sand production in oil wells, which occurs when producing from unconsolidated or weakly consolidated sandstone reservoirs in the Niger Delta. Sand production is one of the most critical problems in oil production as it causes equipment damage and reduces productivity while increasing operational cost. This study focuses on evaluating the reservoir and formation characteristics, such as grain size distribution, permeability, and formation strength that guides the size selection of gravel and screens while also describing various methods of gravel packing and sand screens. To predict the effect of gravel pack and sand screens in oil wells, the performance of two wells were modelled using PROSPER, a production and system performance software. The results obtained showed that while fracture pack method which provides a dual benefit of formation stimulation and effective sand control, boosted more than 10% increase in oil and gas rate across both wells, conventional gravel pack and sand screens offer comparable sand control efficiency with a significantly reduced completion sand improved well longevity without the high financial and technical demands of frac pack operations.
Bird’s eye chili (Capsicum frutescens L.) is one of Indonesia’s high-value horticultural commodities with significant economic potential for smallholder farmers. This research was conducted to determine the cost structure, income level, and economic feasibility of bird’s eye chili farming. The study took place in Sukalaksana Village, Sukanagara District, Cianjur Regency, from October to December 2023. A quantitative approach was applied, and data were collected through field observation and direct interviews with bird’s eye chili farmers. The analytical methods included total cost analysis using the formula TC = TFC + TVC, income analysis using π = TR – TC, and farming feasibility assessment using the R/C ratio. The results showed that the total production cost incurred was IDR 924,093,369 per hectare, while the total revenue obtained was IDR 1,207,660,000 per hectare, resulting in a farming income of IDR 283,566,631 per hectare.

This research highlights Alzheimer’s disease (AD) and its issue on the global population. It examines the causes of AD through environmental factors, such as age and the molecular level, including improper protein folding, production and protein aggregation, through which analysis of different forms of disease modeling for AD arises. Various forms of disease models that were examined included mouse models, 2D models, organoid models, computational models and Brain on Chip models. The research examined and emphasized each model's benefits and disadvantages, and concluded that the Brain on Chip was more efficient in modeling AD. This is because it incorporates more variables, such as the blood-brain barrier, and several cellular mechanisms undermining the potential factor of initiating AD, such as the development of Aβ plaques and their impact on blood blood-brain barrier, and overall synaptic connections. Therefore, this results in the deterioration of the neural connection. This paper promotes the need for further studies and research on better modeling of AD.

Nigeria’s 330 kV transmission grid forms the backbone of bulk power transfer from generating stations to load centers across its six geopolitical zones. The network, modeled as a 58-bus system, experiences persistent technical losses, congestion, voltage instability, and limited transfer capability. Flexible AC Transmission Systems (FACTS) devices offer advanced solutions to improve efficiency by dynamically controlling voltage profiles, power flows, and network impedances. This paper characterizes the existing Nigerian 58-bus, 330 kV transmission network, identifies operational inefficiencies, and investigates the potential of FACTS technologies—such as Static Var Compensators (SVC), Static Synchronous Compensators (STATCOM), Thyristor Controlled Series Capacitors (TCSC), and Unified Power Flow Controllers (UPFC)—to enhance system efficiency. Simulation-based methodologies are outlined to quantify loss reduction, congestion relief, and transfer capability improvement. Findings highlight that strategic deployment of FACTS can reduce system losses by over 15%, improve voltage profiles within statutory limits, and increase available transfer capability, thereby strengthening the reliability and efficiency of Nigeria’s power delivery system.
La présente étude se propose d'analyser l'impact de la culture "politique" des leaders Congolais sur leur gestion de la démocratie en tant que système politique expérimenté en République démocratique du Congo. Elle démontre que dans le contexte congolais, la culture en général, et la culture politique en particulier, impose des limites au système politique démocratique, qui, au lieu de produire le développement comme cela est le cas sous d'autres cieux, n'engendre ici que le développement du sous développement.
Tagoloan, Misamis Oriental, Northern Mindanao, Philippines, is the nest of aqua economic hubs, livelihoods, and industries, which has an environmental challenge. The study focuses on Barangay Casinglot, Gracia, Sugbongcogon, and Baluarte, a coastal community along Macajalar Bay that traditionally depends on fishing and farming. However, industrial expansion near the PHIVIDEC Industrial Estate has brought threats like shoreline erosion, pollution, and habitat destruction to the marine life. Phenomenological, ethnographic, and anecdotal recording revealed that the rising tides and storm surges are damaging infrastructure and creeping and washing inland soil, worsened by the lack of mangroves or seawall protection. Despite these issues, the area remains important for small-scale fishing and tourism, offering clean waters and diverse marine life. But rapid, unregulated industrial growth risks harming both nature and human health. The sustainable management solutions include restoring mangrove forests, building seawalls, and enforcing stricter pollution controls. The community-driven efforts, combined with strong government support, are essential to protect both the environment and the people’s livelihoods. Action is needed to prevent unfavorable, unhealthy ecological development that respects both nature and human well-being. It’s a call to protect this dynamic coast through inclusive, resilient policy.
Motion sickness and its coping mechanisms were studied on the purposively selected twenty (20) first year women student in the College of Education, Tagoloan Community College as the participants. It utilizes the Phenomenological, ethnographical and anecdotal recording with the aid on the Focus Group Discussions (FGD) to explore the lived experiences on the motion sickness and its coping mechanism. And, to shed light how and why absenteeism happened in the classroom setting. As explore farther that dizziness, vomiting, and nausea were common symptoms, they did not always correlate with lower general weighted average. However, the ability to concentrate, complete tasks, and retain information during lectures was significantly affected. The study identified environmental factors, relaxation techniques, and distraction methods as strategies for managing symptoms. Addressing motion sickness can enhance students' academic performance and contribute to a more inclusive educational environment.
This paper aim to classify, detect and mitigate the technical faults in a synchronous generators in a power generation system. The paper utilized artificial neural network, ANN to ensure prompt fault classification, detection and mitigation to avoid a sudden shut down of the plant due to fault cascade. The case study was the synchronous machine plant being utilized in Ibom power plant in Akwaibom state, Nigeria. The operational parameters of the plant was obtained with the mathematical model carried out to obtain the speed and temperature of various fault conditions. The conditions considered in the modeling were the operation of the plant at healthy or normal condition, lack of frequency control and occurrence of wear and tear in the rotor and machine blade. For the identification and classification of faults, the input to the ANN was the speed and temperature of the plant at normal condition and faulty condition while the target data was the fault classification code. For the fault mitigation process, the input data to the ANN was the speed and temperature of the plant at faulty condition while the target data to the ANN model was the speed and temperature of the plant at healthy or normal condition. From the outcome of the simulation, the speed and temperature data were obtained.
