Genotype and Phenotype Interactions Influencing External Egg Quality Traits in Wild-Type Japanese Quails Reared in Borno State, Nigeria
(African Scientific Research and Innovation Council (ASRIC), 2025-12-31) Abdulyekeen Olanrewaju Abdulraheem, Abba Mohammed, Maryam Mustapha Shettima, Jimoh Olalekan Aremu, Abdulrazaq Onimisi Raji, Jibrin Aliyu
This research estimated genetic and phenotypic correlations between external egg quality traits in Japanese quails reared in Maiduguri, Borno state, Nigeria using Restricted Maximum Likelihood procedures. A total of 1,320 eggs were collected from 110 quail hens, progeny of the base population at weeks 10, 12, 14, 16, 18 and 20 of age and were used for egg quality analysis. Data were collected on 9 external egg traits; egg weight (EW), egg width (WE), egg height (EH), shell weight (SW), shell ratio (SR), average shell thickness (AVGST), egg shape index (ESI), egg surface area (ESA) and shell weight per unit surface area (SWUS). The estimates were low to high (0.01 - 0.99) for the co-efficients. Meanwhile, they were mostly moderate and high in magnitude indicating potentials for improvement. Highest negative correlations (-0.92) were obtained for EW and SR at ages10 and 12 weeks. At all ages, EW expressed positive genetic correlations with other external qualities, notably, EH, WE and SW. Because of high positive correlation between ESI and SR, eggs with round shape may likely have better SW than others. Phenotypic correlations followed similar patterns with attributes in both magnitude and signs.

LEGAL REGIME OF BIOSAFETY MANAGEMENT IN NIGERIA
(Nnamdi Azikiwe University, Department of Commercial and Property Law, 2026-03-31) Kudirat Abdulkareem; Ahmed A. Muhammed-Mikaaeel; Khadijat Kamaldeen Ibrahim-Eletu
Biosafety management in Nigeria is a critical aspect of ensuring the safe handling, transfer, and use of genetically modified organisms (GMOs) and other biological materials that may pose risks to human health and the environment. The country has established a legal and institutional framework to regulate biosafety, primarily through the National Biosafety Management Agency (NBMA), which was created by the National Biosafety Management Act of 2015 as amended. The method adopted is library-based research (Doctrinal Methodology) from Primary to secondary sources. This paper analyses the function of the agency in the implementation of biosafety policies, risk assessments, and compliance measures. The paper investigates whether Nigeria’s biosafety framework aligns with international agreements such as the Cartagena Protocol on Biosafety, which the country ratified to promote safe biotechnological advancements. The paper discusses topic issues involved, such as the merits and challenges of biotechnology (GMOs), the inadequacy of funding, limited technical expertise, and limited public concerns over GMOs. The paper recommended pragmatic strengthening of biosafety management to enhance stakeholder engagement and pave the way for access to correct global information, capacity-building programs, doing away with political corruption and ensuring stricter enforcement of biosafety regulations.

Design, Fabrication and Performance Evaluation of Solar Brick Oven
(2016-01-01) M. B. Maina; G. M. Ngala; A. T. Abdulrahim
-Bread baking in Maiduguri and environs (north eastern Nigeria) is mainly done in ovens that are fuelled by charcoal sourced from fuel-wood; this process releases harmful greenhouse gasses to the atmosphere with known negative effects on the environment. The demand for fuelwood as energy source by bakeries and household users is increasing while the resource is becoming scarce and costly when available. These require immediate attention by providing alternative sources that are environmentally safe, less costly and accessible locally, so that overdependence on fuel-wood is greatly reduced. A potentially cost effective alternative energy source that is locally available is the solar energy. Three materials (glass, Perspex and aluminum) were used as window/screen materials for the oven, onto which a parabolic solar collector was focused. All the three materials achieved baking bread at different temperatures and time, Glass oven baked at 90oC screen temperature and 120OC oven temperature in 3hours, Perspex oven baked at 150oC screen temperature and 130OC oven temperature in 3 ½ hours and aluminum oven baked at 130oC screen temperature and 150OC oven temperature in 2hours thirty minutes with solar insolation of 850 w/m2 on the test day. Glass and Perspex sustained defect at different temperatures and exposure time. It was observed that aluminum screened solar oven produced bread with oven performance efficiency of 16% while glass screened oven produced bread at 63% efficiency and Perspex screened oven produced bread at 51% efficiency. Temperature profiles within and outside the oven were analyzed (with and without load). Analysis of the experimental results showed that solar radiation, ambient temperature and wind velocity with respect to the screening materials were the most influential factors.

Challenges of ICT Tools for Managerial Functions in Private Secondary Schools
(2024-04) Abdulbaqi Toyin Abdulrahim; Hameed Olalekan Bolaji
The study examined the challenges of Information and Communication Technology (ICT) tools for managerial functions among private secondary school administrators in Ilorin metropolis, Kwara State, Nigeria. Both primary and secondary data were used in the paper. Using a standardized questionnaire, the principals of the private secondary schools in the Ilorin Metropolis provided the data. The total population of Private Secondary Schools within Ilorin Metropolis is 141. The entire population was used as a sample for the study. Findings from the study showed that the majority of the respondents strongly disagreed that there is a non-availability of computers in private secondary schools. The respondents disagreed with the unavailability of internet services in the Ilorin metropolis. The majority of the respondents agree that inadequate Information and Communication Technology tools in private secondary schools. The study concluded that fear of technology use among principals, inadequate Information and Communication Technology tools, and power failure are the challenges confronting the effective use of ICT among principals in private secondary schools in the Ilorin metropolis. The paper recommended that the proprietors of private secondary schools in the Ilorin metropolis should procure more Information and Communication Technology tools. Computer literacy experts should be appointed as the principal. The management should introduce solar energy to save the school from the interrupted power supply.
