(Nig. Soc. for Anim. Prod, 2026-04-01) Jimoh A., Nnabugo P. O. and Aremu J. O
The rising cost of feed and the competitive nature of energy feedstuffs have necessitated the need for alternative feedstuffs in poultry nutrition. This study was conducted to investigate the economics of production of finisher broiler chickens fed maize offal-based diets supplemented with combination of Kingzyme and GrowinAct enzymes. Two hundred Ross 308 four-week old broiler chickens were randomly allocated to five dietary treatments with four replicates and ten birds per replicate in a completely randomized design. The diets had maize offal supplemented with the two enzymes replacing 0, 25, 50, 75 and 100% of maize respectively in treatments T1, T2, T3, T4 and T5.The birds were fed for 4 weeks and data were collected on growth performance and economic parameters. Results indicate that the birds fed dietary treatment T5 had significantly lowest feed intake compared to other treatments which were not significantly different among themselves. The feed cost per kilogram decreased significantly (p<0.05) as the inclusion of enzymes’ supplemented maize offal increased from treatments T1 to T5. Treatment T5 had the significantly lowest feed cost per bird (₦1756.75) while treatment T1 had the significantly highest feed cost per bird (₦2827.38). All the treatments were not significantly different in their effects on final weight, weight gain, and cost per kilogram weight gain, feed conversion ratio, revenue and profit. The cost-to-benefit ratio was significantly lowest for both treatments T4 and T5 whereas treatments T1 to T3 were similar. It was concluded that maize offal supplemented with combination of Kingzyme and GrowinAct enzymes can replace 100% of maize in the diets of finisher broiler chickens.

The management of digital resources has become a critical function of university libraries in the digital age. However, Library Management Systems (LMS) plays a vital role in facilitating the organization, access, and preservation of these resources. The main objective of the study is to identify the types of library management systems adopted for digital resource management in university libraries in South-west, Nigeria. Resource-Based View (RBV) Theory was the theory adopted. Convergent parallel Mixed Method design was employed. The population of the study consisted of 354 librarians and 7 system analysts in selected university libraries using total enumeration techniques which gives a total of 361 respondents out of which 7 e-librarians were interviewed. Questionnaire and interview form are the research instruments for data collection and was validated using face and content validity with the help of two research experts. Reliability test was done by using Cronbach's Alpha method with an average reliability coefficient of 0.74. Quantitative data were analyzed using descriptive and inferential statistics, while qualitative data were transcribed using TurboScribe software and analyzed thematically. Findings revealed that KOHA and Dspace are the major LMS adopted. Librarians used LMS to a great extent (x ̅=3.27). Results showed that technical know-how, user friendliness and ease of use jointly have a significant influence on digital resource management practices (F= 18.234, p< 0.05). The study concludes that library management systems applications influence digital resource management. The study recommends continuous capacity building for librarians and e-librarians, particularly in system configuration, integration, and troubleshooting.

Modeling the compressible flow field of an impulsively started circular cylinder with refined potential flow theory

Understanding compressible flows over bluff bodies, such as circular cylinders, is critical for applications in aerospace engineering, space exploration, and astrophysics. However, the complexity of viscous and unsteady flows, compounded by compressibility effects, remains a challenge for experimental and computational methods. This study explores the compressible flow field of an impulsively started circular cylinder using Refined Potential Flow Theory (RPT), an analytical model that extends classical potential flow theory to include compressibility effects. The governing equations, boundary conditions, and refined stream function are developed to capture the density, velocity, and pressure fields in subsonic and transonic regimes. The results demonstrate that compressibility marginally increases vortex enstrophy at low Reynolds numbers, while its influence on wake flow stability diminishes at higher values. The study reveals that compressibility suppresses shear layer instability, reduces wake velocity deficits, and introduces smaller-scale structures that disrupt the inertial range of turbulence in the low subsonic regime. At higher Mach numbers (M∞≥0.6), local supersonic pockets and shock waves emerge, forming complex λ-shock systems and bow shocks. The predictions of the Strouhal number from RPT show marginal changes for 0.2≤M∞≤0.5, consistent with experimental and computational trends. Although RPT aligns with existing methods to capture key flow features, discrepancies in wake stability and recirculation zone dimensions highlight areas for further refinement. This research underscores the potential of RPT in developing optimization tools that complement experimental and numerical studies, offering valuable insights into compressible flow physics for engineering applications in high-altitude flight and space exploration.

Business Cycle Synchronisation and Regional Migration: Testing the OCA Criteria in the West African Region
(Springer, 2024-12-07) Sodiq Olaiwola JIMOH; Chua Soo Yean
The West African region is on the verge of forming a monetary union. Many studies have examined the feasibility of monetary unions using criteria such as trade and financial integrations. However, labour migration which is one of the criteria has been neglected in previous studies. This study filled the gap by using Abel and Cohen's (Bilateral international migration flow estimates for 200 countries 6(1):1–13, 2019) data between 1996–2019 to examine the impact of migration flows on business cycle synchronisation using the IV-2SLS technique in the West African region. The study reveals that migration flow, specialisation of industry, and financial integrations spur business cycle synchronisation, while regional trade integration does not significantly impact business cycle synchronisation. However, the interactive terms of trade integrations and migration flow positively influenced business cycle synchronisation in the region. These findings suggest a likelihood of optimum currency area in the West African region.

Consumerism Activities and Brand Equity: An Empirical Analysis of Selected Fast-Moving Consumer Goods (FMCG) Manufacturing Companies in Nigeria
(2026-08-01) Adebayo Adeyemi Abdulwasiu; Ajayi, E. O; Olowookere, M. T.
This study examined the effect of Consumerism Activities and Brand Equity: An empirical Analysis in Nigerian fast-moving consumer goods sector with Unilever Nigerian Group of companies as a case study. Survey design was used for the study as data were collected using questionnaires administered on a sample of two hundred and fifty-nine questionnaires (259) received from respondents. The data analysis for the study was undertaken through PLS-SEM. Accordingly, the findings of the study revealed perceived Consumer Right Awareness positively influence the brand loyalty of the consumers of Unilever Group of companies with beta (β = 0.616), t-statistic (t = 17.813) and p value (p = 0.000), while regulatory compliance also has positive and significant relationship with product quality (β = 0.466), t statistics (t = 10.081) and p value (p = 0.000). The study concluded that empowering consumers and adhering to regulations serve as strategic catalysts that transform transparency and legal standards into competitive assets for loyalty and quality. By leveraging these benchmarks as internal controls, firms minimize operational errors while fostering secure, long-term consumer commitment. The study recommends that Unilever should prioritize consumer education and transparent rights policies fosters long-term brand retention and market growth by transforming informed customers into strategic assets. Similarly, integrating regulatory compliance into early production stages secures product reliability and elevates overall market performance through standardized quality excellence.
