This study explores the potential of emerging technologies aiming to transform the Nigerian construction industry. The technologies offer innovative solutions to persistent challenges such as inefficiencies, project delays, cost overruns, and safety risks. The Nigerian construction industry (NCI) is, however, reluctant to implement the technologies because of a lack of substantive comprehension of the features of the innovative technologies. Hence, it has become necessary for the NCI to fully understand the benefits and challenges of the emerging technologies for construction project efficiency. The exploratory literature review identified and examined seventeen (17) emerging technologies, revealing sufficient practical benefits such as enhancing productivity, improving safety, saving costs, and increasing transparency. It also identifies some barriers to their adoption, such as high implementation costs, a lack of skilled professionals, resistance to change, and a technological knowledge gap. The findings suggest that while NCI has started adopting these technologies, significant efforts are needed to address infrastructural limitations and promote skill development. The study concludes by discussing the implications of the findings for construction firms and policymakers and recommendations for future research on the adoption of automation technologies in developing economies, particularly Nigeria.

It seems that Nigeria's educational system has been undergoing improvement only on quantitative when it comes to the number of enrolments in students and schools. However, little effort has been put in place in terms of capacity (physical and material resources, human and financial resources) to manage high enrollment. Resources capacity in secondary schools was nothing to write home about. Most of these resources in secondary school were dilapidated. To worsen the scenario, the scarce resources allocated to these schools are grossly inadequate compared to students' enrollment and come late to the end-users in the public secondary schools. The various stakeholders in the education sector express stern concern about the consistently poor performance of students in secondary schools, especially in mathematics. Since secondary school education is expected to be free by the government, coupled with population increase, it is reasonable for people to take advantage of the free education program. Although the government and private sector of education keep providing qualified teaching staff and non-teaching staff, students in secondary schools still face poor performance in mathematics. The effect of all these on the academic performance in Nigeria's mathematics secondary school students concerns researchers of this empirical work. It is based on these issues and many more that this work sought to empirically investigate the impact of resource factors and quality of instruction on the performance of Nigeria secondary school students in mathematics.

Locust Bean Pod Ash (LBPA) is produced from the calcination of Locust Bean Pod (LBP), an agricultural waste of the African locust bean tree (Parkia biglobosa). This study evaluated the use of LBPA obtained through controlled calcination and open burning as a supplementary cementitious material (SCM) in high-strength concrete (HSC). Cement was replaced by LBPA at 5%, 10%, 15%, and 20% by weight using both ashes—LC for ash produced through calcination at 600 °C, and LO for ash obtained through open burning. Slump and strength were assessed, including compressive strength (100 × 100 × 100 mm cubes) and splitting tensile strength (100 × 200 mm cylinders) up to 90 days. The results showed that LC contained 42.81% and LO contained 10.69% combined SiO₂, Al₂O₃, and Fe₂O₃. The 5% replacement level produced the best performance for both LBPA types. At 90 days, LC and LO improved compressive strength by 14.48% (68.8 N/mm²) and 10.48% (66.4 N/mm²), respectively, compared to the control (60.1 N/mm²). Similarly, the tensile strengths of LC05 and LO05 were 6.74% (4.75 N/mm²) and 4.94% (4.67 N/mm²) higher than the control (4.45 N/mm²). The study concludes that both ashes can be used as SCMs in HSC, with 5% and 10% recommended as optimum replacement levels for calcined and openly burnt LBP, respectively.

Background: Finger knuckle (FK) has gained significant attention as a biometric characteristic in recent years. Its unique features, such as visible lines, wrinkles, and ridges on the external surface of finger knuckles, make it an economically viable option for human identification. FK serves as the foundation for many biometric systems. Aim: This report presents a comprehensive analysis of relevant FK research. The typical FK identification system consists of four steps: image acquisition, image preprocessing, feature extraction, and matching. Various methods have been employed at each stage in this research. Result: The paper highlight state-of-art methods utilized for the recognition of FK.
