ABSTRACT<br> This study aimed to determine heavy metal concentration in some selected fishes (tilapia, mullet, and mudskipper) from river in Andoni Local Government Area, Rivers State. Fishes (Mullet, Tilapia, Mudskipper) and Sediment samples were collected from Andoni River and analysed for Heavy metals (Mn, Ni, Co, Cd, Pb and Cr) using atomic absorption spectrophotometry (AAS). Finding from the study indicated heavy metal accumulation in mullet was in the order Mn>Ni>Co>Cd>Cr>Pb, in mudskipper Mn>Ni>Co>Cd>Pb>Cr, in tilapia Mn>Co>Ni>Cd>Pb>Cr, and in sediment Mn>Ni>Co>Cr>Cd>Pb. Manganese was the highest in all samples, with values ranging from 0.340 ppm (mullet) to 0.676 ppm (sediment). Nickel and cobalt followed, while cadmium, lead, and chromium showed lower concentrations. Lead and chromium were below detectable levels in some samples. The concentrations of all heavy metals in fish and sediment samples were found to be below the World Health Organization (WHO) standard limits. The heavy metal levels detected in the fish species and sediment were within safe limits, indicating minimal risk to human health and the ecosystem. However, continual monitoring is recommended to prevent potential bioaccumulation and contamination over time. Additionally, stricter regulations on pollution sources in the aquatic environment are advised to maintain these safe levels.

The population of this study consists of 90 Industrial Technology Education Students that are undergoing or have undergone industrial training. Of this figure, 28 are 300 level students while 62 are 400 level students. The researcher used questionnaire for data collection. The data gathered for the study was analyzed using descriptive analysis using Statistical Packages for Social Sciences (SPSS). The study revealed that The results of the study reveal that family factors such as father’s wish, mother’s wish, sibling’s wish, uncle’s wish, aunt’s wish, parents’ financial capacity, family’s social class, birth order and family’s religious beliefs do not influence the career choice of the secondary school students. The study also finds that some societal factors influence students’ career choice. Additionally, the study observes that gender and parents’ academic qualification have significant influence on the career choice of students in secondary schools. Based on these, the study recommends that career counsellors should educate the students on a wide range of careers to aid their career exploration process. Counsellors are to assist students to understand that every career has the potential to bring them the respectability and financial reward they desired. The study recommends the need for all stakeholders in education to continue to encourage both male and female students to offer subjects of their choice irrespective of their gender. Parents should be actively involved in the career planning process of students. They should also encourage collaboration amongst researchers and government agencies to carry out career related studies aimed at highlighting job gaps in various industries.

ABSTRACT<br><br> This study investigated the impact of inquiry-based instructional strategies on the academic performance of senior secondary school students in English Language in Kanam Local Government Area of Plateau State, Nigeria. The persistent issue of poor performance in English Language, attributed to traditional teaching methods and low student engagement, prompted the need to explore more effective instructional approaches. The study adopted a quasi-experimental design involving 350 SS II students selected through stratified random sampling from two secondary schools. Students were divided into experimental and control groups; the experimental group was taught using inquiry-based strategies, while the control group was taught using the conventional lecture method. Data were collected using an English Language Performance Test (ELPT), administered as both pre-test and post-test. Analysis was carried out using descriptive and inferential statistics, with hypotheses tested at 0.05 significance level using t-tests. Findings revealed that students exposed to inquiry-based instructional strategies significantly outperformed those taught through traditional methods. Additionally, both male and female students benefitted from the inquiry approach, though male students had slightly higher average scores. The study concludes that inquiry-based instructional strategies enhance students' academic performance in English Language and recommends their integration into classroom practice. Teachers, curriculum planners, and educational stakeholders are encouraged to embrace these strategies to foster deeper understanding, critical thinking, and student engagement in English Language education.

ABSTRACT<br> In today's digital age, educational institutions are increasingly reliant on information systems to manage sensitive student data, making the security of these systems a critical concern. Traditional authentication methods, such as passwords and PINs, are no longer sufficient to protect against sophisticated cyber threats. This project explores the implementation of biometric authentication as a more secure alternative for protecting students' information systems. Biometric authentication, which utilizes unique physiological and behavioral traits like fingerprints, facial recognition, and iris scanning, offers enhanced security by ensuring that only authorized individuals can access sensitive data. The study begins with a comprehensive literature review, highlighting the limitations of traditional authentication methods and the advantages of biometric systems across various sectors, including banking, healthcare, and government. The review also identifies key challenges in implementing biometric authentication in educational settings, such as technical integration, privacy concerns, and legal implications. To address these challenges, the study proposes a theoretical framework that combines established information security models with empirical validation in educational contexts. Through case studies and empirical analysis, the project examines the current state of biometric authentication in Confluence University of Science and Technology (CUSTECH), Osara, Kogi State, assessing its impact on data security, user acceptance, and ethical considerations.

This project deals with an effective way of finding empty spaces and managing the number of vehicles moving in and out in complex multi storeyed parking structures by detecting a vehicle using IR sensors and thus providing a feedback. The fully automated smart car parking system is rudimental and does not require heavy lines of code nor expensive equipment. It is a simple circuit built for the exact need of purpose. This automated system is used to find the vacancy in parking spaces available and navigate the driver to reach the desired space using visuals and in an effective manner, thus reducing search time. This system is required for malls, multi storey parking structures, IT hubs and parking facilities. This makes sure the requirement of labour is insubstantial

ABSTRACT<br> The aim of the study was to analyze blood sodium levels in normal persons from Isoko North Ozoro, Delta State, using proprietary spectrophotometry method. A total of twenty persons (adult male and female) comprising of seven males (35%) and thirteen females (65%) were used for the analysis. Blood samples were collected from some selected normal persons using hypodermi syringe and transported to the laboratory for analysis. The blood was allowed to clot enabling the serum to be obtained from it. A protein free filtrate was prepared and process for absorbance reading using the proprietary uranium magnesium acetate reagent. The result showed mean concentrations for the males within 51.215 to 139. 05 and for the female 32. 005 to 177.43. The result showed that among the 20 persons analysed for blood sodium level only a male was within normal range (14.3%), six males were below normal range (85.7%) and no male was above normal range; While for the females, no female was within normal range, ten were below normal range (76.9%) and three were above normal range (23.1%).The findings of the study showed that males were found to have normal sodium level of 14.3% as compared to females, high sodium level (hypernatremia) was found more in females (23.1%) than males (none) while low sodium level (hyponatremia) was found more in males (85.7%) than females (76.9%). Generally, the findings of the study showed that low sodium (hyponatremia) was more common in males and females than high sodium (hypernatremia).The ANOVA from the study indicates that there is significance difference among the groups for male and no significant difference amongst the groups for female as the p-value is significantly higher than the Ftestvalue in males and lower in females. The results obtain for correlation of variance indicated that the method can be developed for used.
