Year of Publication
Publication Type
Abstract
This study represents a comparative mineralogical and geochemical evaluation of clay deposits from Igo and Okhoro, located within the Benin Formation of Southern Nigeria, with the aim of determining their industrial suitability and economic potential. Field observations revealed that the Igo clay occurs as reddish to brownish lateritic clay interbedded with sands, whereas the khoro clay is predominantly light grey with brown patches and is more quartz-rich. X-ray Fluorescence (XRF) analysis of the Igo samples shows high concentrations of silica (SiO₂: with mean value 68.57%) and alumina (Al₂O₃: with mean value 22.59%), with relatively low levels of fluxing oxides. In contrast, the Okhoro samples contain lower silica (mean 59.25%), comparable alumina (mean 21.86%), but noticeably higher iron oxide (Fe₂O₃: up to 7.34%) Trace element concentrations in both locations were generally low, indicating minimal impurity influence on industrial applications. The X-ray Diffraction (XRD) data reveal that the Igo clays are dominated by kaolinite (24.5–45%) and quartz (36–62%), with significant amounts of feldspar minerals (orthoclase and albite) and muscovite. Okhoro samples, however, are overwhelmingly quartz-dominated (88.6–98.04%) with only minor kaolinite (0.98–9.42%) and no detectable feldspars, signifying a highly mature, intensely weathered sediment. These mineralogical differences indicate that Igo represents a submature kaolinite-quartz-feldspathic clay, while Okhoro represents a supermature quartzose deposit. Comparisons with industrial specifications show that both clay types meet some requirements for refractory bricks, hough beneficiation is needed to adjust fluxing oxide levels. Igo clays, due to their higher kaolinite content and natural feldspar fluxes, exhibit stronger potential for ceramic applications, including tiles, earthenware, and fillers for paint or rubber after processing. Okhoro clays, because of their extreme quartz dominance , are more suitable as construction fillers, low-grade refractory blends, or materials for brick manufacturing. Overall, the Igo clay deposit displays broader and more economically valuable industrial potential than the Okhoro deposit, which is limited by its mineralogical maturity.

Year of Publication
Publication Type
Abstract
The increasing environmental impact of petroleum-based plastics has intensified the global search for renewable, biodegradable alternatives. Agricultural wastes, particularly cassava and potato peels, offer promising sources of starch for sustainable bioplastic production. This study focused on the comparative development and evaluation of bioplastic films produced from cassava peel starch (CPS) and potato peel starch (PPS), using identical formulation and processing conditions. The aim was to assess how starch source influences the physicochemical, mechanical, structural, and biodegradation characteristics of the resulting films.Starch was extracted from the peels through sedimentation and drying processes, and the yield was determined gravimetrically. Bioplastic films were prepared using a standard casting method. The films were characterized for tensile strength, elongation at break, thickness, water absorption, solubility, and biodegradability. Structural and morphological properties were examined through visual observation and scanning electron microscopy (SEM). The results revealed that cassava peel produced a higher starch yield (18.6%) compared to potato peel (14.9%), confirming its superior extraction efficiency. CPS films exhibited greater tensile strength (4.85 MPa) and Young’s modulus (62 MPa), indicating stronger and more rigid films, while PPS films displayed higher elongation at break (32%), signifying greater flexibility. SEM analysis showed smoother and more homogeneous surfaces in CPS films, whereas PPS films exhibited minor surface irregularities. Both films demonstrated good biodegradability under soil burial, with PPS degrading slightly faster due to its higher hydrophilicity. Overall, the findings establish cassava and potato peel starches as viable raw materials for biodegradable film production, promoting waste valorization and environmental sustainability. The higher yield and superior mechanical integrity of cassava peel starch films suggest greater industrial potential, particularly for ecofriendly packaging applications.

A CENTRALIZED ELECTRICAL HEALTH RECORD MANAGEMENT SYSTEM

Year of Publication
Publication Type
Abstract
Efficient healthcare delivery relies heavily on accurate, accessible, and secure patient information. In Nigeria, the current method of managing patient records remains largely manual, fragmented, and uncoordinated across different healthcare facilities. This has led to frequent duplication of medical tests, prolonged waiting times, and poor continuity of care. The need for a centralized and interoperable digital solution is therefore essential in improving patient outcomes and overall healthcare efficiency. This roject focuses on the design and prototype implementation of a web-based Electronic Health Record (EHR) system named HealthHive. The system aims to consolidate patient medical data from multiple hospitals into a single, secure, and user-friendly platform accessible to patients, healthcare providers, and administrators. HealthHive emphasize interoperability, scalability, and data security while ensuring that patient privacy is upheld through role-based access control and encrypted communication. The project adopts the Object-Oriented Analysis and Design (OOAD) approach, with modeling tools such as Use Case Diagrams and Class Diagrams utilized to represent the system’s architecture and interactions. The proposed system demonstrates how centralized digital records can minimize redundancies, promote data sharing between healthcare institutions, and enhance decision-making through accurate medical histories. Ultimately, this prototype lays the foundation for a national EHR framework capable of transforming healthcare management in Nigeria by improving accessibility, efficiency, and trust within the healthcare ecosystem.

Abstract
Parasitic diseases are problems wherever poultry are raised whether in large commercial operations or in small backyard flocks, and economic losses caused by parasites on poultry can be significant. This study aimed to investigate the prevalence of intestinal parasites in poultry, focusing on chickens and turkeys slaughtered in Benin City, Southern Nigeria. A total of 150 fecal samples were analyzed, comprising samples from 35 broilers, 30 native fowls, 35 layers, and 50 turkeys. The fecal samples was processed using standard Parasitological techniques, and then viewed microscopically. Prevalence rates varied significantly among the different bird species, with the highest total prevalence observed in Native fowls (143.3%), followed by Broilers (60.0%), Layers C(54.3%), and Turkeys (40.0%). Notably, Ascaridia galli was the most prevalent parasite overall (60.4%), with the highest prevalence in native fowls (63.3%). The study also found significant geographical variations in parasite prevalence. In broilers, Ascaridia galli prevalence was significantly different across the LGAs (p=0.045), with the highest rate in Ikpoba-Okha (33.3%). Similarly, in native fowls, Strongyloides avium showed a significant difference (p=0.003), with a high prevalence of 60.0% in Ikpoba-Okha. In turkeys, the prevalence of Ascaridia galli varied significantly across the LGAs (p=0.043). The findings highlight that poultry in the study area are widely infected with gastrointestinal parasites, emphasizing the need for targeted management strategies and regular treatment to mitigate infection risks

ECONOMY OF FEED CONVERSION OF WEANER RABBITS FED GUINEA GRASS LEAFMEAL AS A REPLACEMENT FOR SOYBEAN MEAL

Year of Publication
Publication Type
Abstract
The study investigated the economy of feed conversion of weaner rabbits fed diets in which soybean meal (SBM) was partially replaced with Guinea grass (Panicum maximum) leaf meal (GGLM). Rising feed costs, especially for conventional protein sources like soybean meal, have prompted the exploration of locally available and low-cost alternatives to enhance the profitability of rabbit roduction. Twenty weaner rabbits aged 4–6 weeks were randomly assigned to four dietary treatments containing 0%, 10%, 20%, and 30% GGLM as replacement levels for SBM in a completely randomized design, with five rabbits per treatment. The diets were formulated to be iso-nitrogenous and iso-caloric, and the feeding trial lasted ten weeks. Parameters measured included feed intake, weight gain, feed conversion ratio (FCR), cost of feed consumed, cost per kilogram weight gain, total production cost, and net profit. Results indicated that inclusion of GGLM up to 20% did not significantly affect growth performance or FCR compared to the control diet. However, feed cost per kilogram decreased progressively with higher inclusion levels of GGLM, with the lowest feed cost and highest net profit recorded at 30% inclusion. Economic analysis showed that substituting GGLM for SBM substantially reduced feed costs without adverse effects on productivity at moderate inclusion levels. The study concludes that partial
replacement of soybean meal with Guinea grass leaf meal (up to 30%) in weaner rabbit diets is economically advantageous and supports efficient feed utilization. It is therefore recommended for smallholder and commercial rabbit producers as a cost- effective strategy for improving profitability and sustainability in rabbit production systems.

Year of Publication
Publication Type
Abstract
This study looked at how Coca-Cola Nigeria Plc's marketing strategy in Benin City was affected 0by product differentiation and market segmentation. The goal of the study was to ascertain how these tactics affect the company's competitive advantage, consumer preference, and marketing performance. Data was gathered from 400 respondents utilizing structured questions and a descriptive survey approach. Using SPSS version 29.0, the data were examined using multiple regression analysis, descriptive statistics, and Pearson correlation. The results showed that Coca-Cola's marketing strategy benefits considerably from product differentiation, suggesting that distinctive taste, packaging, and branding have a big impact on consumer behavior. However, market segmentation had a favorable but statistically negligible effect, indicating that without considerable distinction, segmentation by itself is not a reliable indicator of marketing success. The regression results also showed that the independent variables accounted for 28.1% of the variances in Coca-Cola's marketing strategy. The analysis comes to the conclusion that Coca-Cola's product diversification strategy, bolstered by modest segmentation initiatives, is the main factor driving the company's market success in Benin City. It suggests that Coca-Cola improve marketing efficacy and maintain brand competitiveness by fortifying its segmentation strategies and incorporating them with distinctiveness.

Year of Publication
Publication Type
Abstract
This study investigated the hydrogeological evaluation of borehole water contamination near a solid waste dumpsite in Iyowa, Benin City, Nigeria. The aim was to assess how dumpsite leachate affects groundwater quality by examining physicochemical, microbiological, and heavy metal parameters. Five borehole samples were collected at varying elevations and distances around the dumpsite (coordinates: 6°27′29″N–6°27′44″N, 5°36′10″E–5°36′37″E) using GPS mapping and WHO-recommended sampling procedures. Laboratory analyses covered pH, electrical conductivity (EC), total dissolved solids (TDS), turbidity, nitrate, sulphate, phosphate, and selected metals (Pb, Fe, Cr, Zn) determined by Atomic Absorption Spectrophotometry (AAS), alongside microbial tests for total coliforms and E. coli. The results (Tables 4.1–4.3, Figures 1–2) showed acidic groundwater (pH 5.19–6.14) below WHO limits (6.5–8.5), with low alkalinity (4–6 mg/L) and elevated metal concentrations: Pb (0.106–0.428 mg/L), Fe (2.98–7.51 mg/L), and Cr (0.37–3.87 mg/L), all exceeding the permissible limits of 0.01, 0.3, and 0.05 mg/L respectively. Potassium spiked at 55.8 mg/L in the borehole closest to the dumpsite (Sample 2), indicating direct leachate influence. Microbial tests showed absence of coliforms and E. coli, but minor heterotrophic bacteria (1 CFU/mL). Overall, the acidic and metal-enriched groundwater reveals significant leachate intrusion linked to dumpsite proximity, making the borehole water unsafe for domestic consumption without treatment. The findings highlight the need for controlled waste disposal, borehole siting regulation, and continuous groundwater monitoring in Iyowa.
