    The 21st century digital era is faced with utilizing ICT in the classroom for aiding teaching and learning opportunities amongst teachers and learners. The roles and challenges of ICT in enhancing the teaching and learning process in a Government Comprehensive Secondary school, Obio-Akpor, Rivers State was carried out. The descriptive survey was used in this research. The simple random sampling method was utilized to collect a sample size of (150) respondents which consists of 115 and 35 females and males respectively. The descriptive statistics of mean, frequency and percentages were used to analyze the collected data. However, the study unveil the gross unavailability of facilities to fully support the implementation and integration of information and communication technology in the school. It also specified the various roles of ICT in education among which are eliminating the barriers of distance learning, making teaching and learning more interesting and impactful, etc. However, studying the issues and challenges related to ICT use in teaching and learning can assist teachers in overcoming the foreseen limitations and become successful technology users. The findings revealed a large percentage of inadequacy in the usage and availability of ICT g adgets for teaching and learning. With the changes in modern technologies, it is recommended that ICT gadgets be provided in public secondary schools in the State for effective teaching and learning process.

    MAXIGRAIN® ENZYME IMPROVES LAYING PERFORMANCE OF LAYER QUAILS (CORTUNIX CORTUNIX JAPONICA) FED SUGARCANE SCRAPPING MEAL-BASED DIETS
    (Department of Animal Science, Nasarawa State University Keffi, 2014-09-26) Tuleun, C. D.; Alu, S.E.; Carew, S.N.; Kaankuka, F. G.
    Three hundred and sixty 6 weeks old laying quails were utilized in an 8 week experiment to evaluate the effects of Maxigrain® enzyme supplementation of sugarcane scrapping meal-based diets on growth rate and laying parameters of layer Japanese quails (Coturnix coturnix japonica). Six diets tagged T10, T10IOO, T102oo, TI5, TI5ioo and T152oo were formulated to be isonitrogenous (207cCP) and isocaloric (2786.72 Kcal/kg ME). Diets T10 TIOiooand T102oo contained 10% crude fibre while T15, T15/oo mid T102oo contained 157o crude fibre. The enzyme was include at 0,100 and 200ppm thus, treatments TJOiw, T1020o. TJ5!0o and T15200 contained 100 and 200pm of the enzyme such that T10 and TJ5 functioned as the control for TlOioo mid T10200, and T15joo and T15:oo respectively. The birds were randomly allocated to the 6 dietary treatments at the rate of 60 birds per diet. Each treatment was replicated 4 times in a 3 x 2 factorial arrangement having 13 and 2 sexually mature female and male birds per replicate, respectively. The results showed that dietary fibre improved (P<0.05) dressing percentage (61.62 and 74.117o), white blood cells count (267.30 and 268.90 x10*/ml) and neutrophils (1.83 and 2.007o) but reduced red blood cells count (3.39 and 3.34 xlCf/ml), lymphocytes (98.17 and 98.177o) and haemoglobin (14.12 and 13.93 g/dl). Birds fed the no-enzyme and 100 ppm enzyme supplemented diets produced better (P<0.05) white blood cells count (2Z5.50 xlO*/ml). Lymphocytes (98.257o) and neutrophils (2.257o) were improved (P<0.05) in bird fed the no-enzyme and 200 ppm enzyme supplemented diets, and 100 ppm enzyme supplemented diets only. The interaction of enzyme and dietary fibre influenced (P<0.05) weight of heart as birds fed the T15 (0.547o), T15joo (0.577o) and T152m (0.637o) had the heaviest weight while those fed the T15200 (10.067c) had the heaviest weight of gastrointestinal tract than those fed the other treated diets. In view of the comparable performances of the birds fed the high fibre-enzyme supplemented diets, fanners can use the combination for quail farming without affecting the meat quality and health of the birds

    Secured Cloud Data Storage Encryption Using Post-Quantum Cryptography
    (Department of Computer Science, Nasarawa State University Keffi, 2022-01-06) Alu, S.E.; Yunana, Kefas; Ogah, Muhammad Usman
    Cloud computing is evolving daily for securing large data in diverse industries and organizations. The two major challenges about cloud storage are reliability and security. Clients cannot entrust their data to another company without any assurance that they can access their information anytime and no third party will be granted access to it. Data can also be requested from the cloud by the users. However, uploading data in the cloud faces some security issues due to cyber threats and prevalent fraudulent activities. With advancement in technology and research, different solutions have evolved to protect cloud data. Cryptographic techniques utilizing different encryption mechanisms are used to protect the data and ensure its integrity. The existing cryptographic techniques are classical and vulnerable to attacks by quantum computers. In addition, the classical computers utilizes multiple algorithms for encryption and decryption which takes time to encrypt and decrypt a file. In this paper, we presented an optimized new security mechanism using post- quantum cryptography to provide block-wise security to cloud data storage irrespective of the size of the file uploaded or downloaded.

    Towards An Enhanced Smartphone Security Using Distributed Ledger Technology (Blockchain)
    (Department of Computer Science, Nasarawa State University Keffi, 2022-03-03) Alu, S.E.; Ogah, Muhammad Usman; Yakubu, Awal J.
    Smartphones have now become an important tool in our daily lives, even to the level of addiction for some individuals. Due to the increase in the usage of cell phones, security issue has become a major challenge in mobile transactions. In this paper, smartphone security/vulnerabilities, and awareness on data security challenges were discussed. Due to big data and massive usage of online data, security implementation in cellphones cannot be under-estimated. However, diverse data protective measures such as fingerprint sensors, Face ID, iris scanner for cellphones and biometric security features, smartphones have existed but could not provide adequate mitigate against any security breach. As a result, smartphone producers encourage their users to safeguard their devices with strong passwords. However, with all of this security counter measures, loopholes still plague the mobile phones such that antivirus software are inadequate in protecting phone users against cyber-attacks. Blockchain is an alternative that evolve to boost the security of transactions using smartphones to clamp down on any possibility of external breach. This paper also expound the use of visual sim technology other than the existing physical Sim cards in providing more security enhancement in smartphones.
