Published: March 2021

This study was conducted to evaluate some aspects of the reproductive biology of the African Bonytongue Heterotis niloticus from the Great Kwa River, Cross River State Nigeria with the view to encourage conservation and rational measures for sustainable management of the species. A total of 62 matured H. niloticus were sampled and their gonadosomatic index (GSI), hepatosomatic index (HSI), condition factor, fecundity and egg diameter (mm) were studied in other to determine the spawning season of the fish. Gonadosomatic index and hepatosomatic index showed an inverse relationship during spawning seasons. Total length (TL-cm) ranged between 47.1 cm – 76.2 cm and total weight (TW – g) ranged between 4300g - 1169g with sex ratio of 1:1.2 (male: female) revealing a dominant female population. Fecundity ranged from 511 oocytes (48.4cm TL; 1.69 kg wt, 5.9g gonad weight) to 7822 oocytes (69.3cm TL, 3.11kg wt. 14.9g gonad weight). The regression equation derived from the scattered diagram in the relationship between fecundity and total weight, total length gonadosomatic index and length-weight is; F= 6.6231TW0.837, R2= 0.2456; F= 5.1112TL1.6367, R2= 0.1606; F= 10680GSI0.9276, R2= 0.6567; TW= 0.4072TL2.0987, R2= 0.7533, the relationship were significant (p < 0.05). Fecundity and ovary weight relationship showed a positive correlation coefficient of 1. The highest egg diameter (0.92±0.01) was recorded in May and other months with corresponding high gonadosomatic index performance to confirm spawning period. In view to encourage conservation by investigating measures for sustainable management of the species, this study observed that H. niloticus spawns throughout the year.

The study was carried out with the purpose of assessing school record management in FCT secondary schools. Record management is the area of administrative management that is concerned with achieving economy and efficiency in the creation, maintenance, use and disposal of records of an organization throughout its life cycle. Implementing good record management practices in schools would provide information for educational planners and administrators, serves as historical source for documenting history of the school. School records comprise all existing and accessible records, books, files and other documents containing useful information that relates to what goes on in the school system They are evaluation tools for accessing progress made by schools and also show evidence of compliance with legislative laws. The descriptive research design was used for this study. The population was drawn from ten (10) secondary schools in FCT. The instrument for data collection comprised of questionnaire titled “Assessment of School Record Management in Secondary Schools in FCT” (ASRMSS). A sample size of eighty respondents from schools was used. Simple percentage was adopted in analyzing the research questions while chi-square was adopted in analyzing the hypotheses. Research findings revealed that the various record books used in schools include: log-book, attendance register, lesson plan, syllabus, staff movement book, visitors’ book, admission and withdrawal register, to mention a few. It was also revealed in the findings that most of the records in school are not properly kept. Also, timely supply of school records, availability of funds, teachers’ training and proper back up of records were the solutions proffered by respondents. It was however recommended that stakeholders in the school should make use of the school’s record books for efficiency purposes. Furthermore, stakeholders should ensure timely update of record materials and finally, delegation and follow-up on record procedures should be given adequate attention by school principals.

Authors: Marwa N. J. , Choji J. , Dalumo B. D. 
Published: March 2021

Good spatial ability skills are an important component of an engineer’s ability to create and interpret engineering drawings, which is demanding in thinking, being a problem-solving process. The ability of an engineer to visualize in 3D is a cognitive skill that is attached to success in basic engineering drawing subjects. Engineering and technology education students need good spatial ability skills to understand several topics in basic engineering drawings like orthographic projection, axonometric drawing, sectional view, and hidden details drawings. This study aims at improving spatial ability skills using a solid pair model among first-year technical education students of Kaduna State College of Education Gidan Waya. A Quasi-experimental research design was used for the study, a standards pre and post-test were used to conduct a visualization transformation assessment to measure the students’ level of spatial ability skills. The study shows that after treatment using a solid pair model, the student without prior knowledge in basic engineering performed above average, likewise students with prior knowledge in the control and experimental group performed above average. The results indicate that a solid pair model was effective for improving spatial ability skills among first-year technical education students. This study implies to educators that there is need to appropriately enforce the use of a solid pair model for effective teaching and learning of basic engineering drawing. It is, therefore, affirmed that the use of a solid pair model in teaching basic engineering drawings should be enhanced with other teaching methods.

TEACHERS PERCEPTION OF THE USE OF ICT AS AN INSTRUCTIONAL TOOL IN SCIENCE AND MATHEMATICS IN NIGERIA SECONDARY EDUCATION
Authors: Ebire F. A. 
Published: March 2021

The lagging performance of students in science and mathematics in West African Senior School Certificate Examination (WASSCE) points to a serious challenge requiring the intervention of the government, as we know; education is the bedrock of any nation. The application of ICT tools in teaching science and mathematics in Nigeria can be said to have minimally improved student performance in recent times. Though the government of Nigeria has made a laudable effort in these regards; it has little or no impact in teaching science and mathematics in Nigeria secondary education. Thus, this study aimed at examining the perception of teachers towards the use of ICT as an instructional tool in science and mathematics within Nigeria secondary education. The research employs a quantitative research design in which a sample of sixty-three (63) science and forty (40) mathematics teachers from government secondary schools in Abuja, Nigeria were interviewed. The instrument for data collection was a semi-structured questionnaire titled “Teacher’s Perception on ICT Use Model (TPIUM)” based on the Technology Acceptance Model (TAM) by Davis, 1989. Statistical analysis of the data obtained showed that Perceived usefulness (PU) had the strongest impact on Behavioral intention (BI) and Attitude toward use (AT) of ICT tools by teachers. The findings of this study also revealed that outdated government policies to support ICT use in science and mathematics posed a big challenge and more consequential is the inadequate skills of teachers in using ICT tools. The study therefore recommends that the government should endeavor to put in place adequate training and retraining of teachers on how to effectively fuse and use ICT tools in teaching mathematics and other science subjects in Nigeria.

EVALUATION OF AKPET GT9 GAS CONDENSATE RESERVOIR PERFORMANCE
Authors: Okotie S. , Ogbarode N. O. 
Published: March 2021

To effectively evaluate a gas condensate reservoir performance, the reservoir engineer must have a reasonable amount of knowledge about the reservoir to adequately analyze the reservoir performance and predict future production under various modes of operation. Due to the multiphase flow that exists in the reservoir, characterization of gas condensate reservoirs is often a difficult task with the variation of its overall composition in both space and time during production which complicates well deliverability analysis and the sizing of surface facilities. This study is primarily concern with the evaluation of a gas condensate reservoir performance of Akpet GT 9 Reservoir in the Niger Delta region of Nigeria with material balance analysis tool “MBal” without having to run numerical simulations. The result obtained with MBal on the analysis of Akpet GT 9 reservoir gave 23.934 Bscf of gas initially in place which compares favorably with the volume obtained from volumetric techniques. Results also shows that the most likely aquifer model is the Hurst–Van Everdingen - Dake radial aquifer and the reservoir is supported by a combined drive of water influx and fluid expansion.

PARTICLE SWARM OPTIMIZATION OF SOLUTION GAS OIL RATIO
Authors: Okotie S. , Fasanya A. E. 
Published: March 2021

Reservoir fluid properties are very important in reservoir engineering computations such as material balance calculation, well test analysis, reserves estimate and numerical reservoir simulations. Ideally, these properties should be obtained from laboratory pressure-volume-temperature (PVT) analysis. Quite often, however, these measurements are either not available, or very costly to obtain. In such cases, empirically derived correlations are used to estimate the needed properties, all computation therefore, will depend on the accuracy of the correlations used for estimating the fluid properties. Hence in this study, Standing’s correlation for estimating the solution gas-oil ratio was optimized using a particle swarm optimization (PSO) algorithm to minimize the error associated in estimating solution gas-oil ratio from correlation at various depletion pressure. The optimized correlation was taken as a function of bubble point pressure, API gravity, gas gravity and reservoir temperature. PVT data from differential liberation test was used to validate this study’s correlation and the result obtained shows that the optimized correlation for this study matches closely with the experimental values, also the newly optimized correlation was validated with other models and the results gave the least average relative error of 3.34 and a correlation coefficient of 0.998 after 216th successive iterations by the particle swarm optimization algorithm.

Published: March 2021

Inflammation and endothelial dysfunction have been known to be involved in the pathogenesis of cardiovascular diseases. As such, examining the levels of inflammation and endothelial dysfunction is very critical to the prevention of cardiovascular diseases among chronic kidney disease (CKD) patients. This study aimed to investigate the progression of inflammation and endothelial dysfunction among CKD patients in Sokoto. A total of 67 CKD patients were divided into 5 groups based on the stages of their kidney disease calculated using the MDRD 4-variable equation for estimated glomerular filtration rate (eGFR). The presence of inflammation was determined by C-Reactive Protein (CRP) and Tumor Necrosis Factor alpha, while endothelial dysfunction was determined by the levels of Asymmetric dimethylarginine (ADMA) using ELISA kits. The mean eGFR of the patients was 49.97 ± 4.69 ml/min/1.73m2. There was significant increase (p<0.05) in CRP, TNF-α and ADMA of the CKD patients across the stages as compared to the non-CKD subjects. It was observed that as the CRP, TNF-α and ADMA increase, the eGFR significantly (p<0.05) decreases. Both CRP and TNF-α indicated a significantly positive correlation (p<0.05) with ADMA. The results indicated progressive increase in inflammation and endothelial dysfunction as CKD deteriorates. In addition, increased levels of inflammation could directly affect endothelial dysfunction, thereby aggravating cardiovascular morbidity and mortality among CKD patients in Sokoto.

Published: March 2021

Information and communications technology (ICT) in recent times has become a viable strategic policy option adopted by many businesses in order to compete favorably in a competitive and dynamic ICT driven market. This strategic move by business organizations is being hindered by some challenges which has invariably reduced the benefits accruable from ICT deployment for business operations especially in the inventory management. Primary data formed the methodology of the study. Descriptive and inferential statistics were used to analyze data obtained through the administration of structured questionnaire. It was established during the field survey that challenges facing the use of ICT had impacted negatively on the performance of inventory management in the Nigerian brewery industry during the period under study. It was also revealed that the cost of software was a major challenge in the industry and conclude that the identified challenges had significant effect on customers' satisfaction of the firms in the Nigerian brewery industry. It is recommended that management of firms in the Nigerian brewery industry should collaborate with software developers in Nigerian to develop a software that will be a replica of ERP but should be efficient, effective and affordable for inventory management and other operations in the industry.

Authors: Igboeli U. H. , Bisallah H. I. 
Published: March 2021

Information Communication Technology has generally been acclaimed as an important tool exploited by medium and large-scale enterprises for boosting profitability and enhancing viability. Though Small and Medium Scale Enterprises (SMEs) constitutes a major percentage of businesses in most countries, their ICT adoption rate is still low. This study examined the role of ICT as a tool that SMEs can deploy for the economic development of Nigeria. A questionnaire was employed and administered to a total of 175 SMEs randomly chosen from five different sectors of the Nigeria economy (educational, micro finance, transport, commerce and hospitality). Chi-square test was used to evaluate the hypothesis and the findings of the research revealed that (1) low awareness level of the benefits of ICT incorporation in the management process of most SMEs has been a major cause of its low adoption; (2) poor media transmission framework, high cost of ICT hardware, deficient government support and legislation for internet business among other factors have hindered the adoption of ICT in the management process of SMEs; (3) high cost of funds in Nigeria have also made it unprofitable for SMEs to source fund for ICT expansion and implementation. The research recommends among other measures, the investment on infrastructure and adequate incentives to promote the utilization of ICT among SMEs. Investment banks and other specialized institutions should brace up with their responsibilities and promote local industries through affordable credit schemes.

Improving the optical response of glass host with two or more strong network formers via suitable controlled of rare earth ions is the key issue in the fabrication of optical based glass for solid state lasers and light emitting devices. Hence, we report the Nd3+ concentration dependent on optical parameters such as absorption edge, optical band gap (direct and indirect) and Urbach’s energy of gadolinium borophospho-tellurite glasses with chemical composition of 10Gd2O + 30B2O3 + 20P2O5 + (40-)TeO2 + Nd2O3 (where 0.0 ≤ x ≤ 1.0 mol%). The glass samples were synthesized by convectional melt quenching method and characterized through X-Ray Diffraction (XRD) and Ultraviolet Visible Near-Infrared (UV-Vis-NIR) measurements. The amorphous nature of these glasses was confirmed by X-Ray diffraction pattern while the UV-Vis-NIR spectra revealed six absorption peaks corresponding to the transition from ground level 4I9/2 to the various excited state of Nd3+ ions. It was found that the investigated range of Nd3+ doping concentrations has a great influence on aforementioned parameters. The excellent optical features established in the present glass host suggest their potentiality for solid-state lasers and other photonic applications.

Authors: Adeniji E. S. , Bamigbola A. A. 
Published: March 2021

In this study, the adsorption and corrosion inhibitive properties of ethanol extract of Dialium guineense leaves for mild steel in 0.5M HCl was studied using gravimetric method. The results obtained showed that the ethanol extract of Dialium guineense leave is a good adsorption inhibitor of Mild Steel in 0.5M HCl. The inhibition efficiency was found to increase with increase in the concentration of ethanol extract of Dialium guineense leave but decreased as the temperature increases. The inhibition efficiency increases up to a maximum of 92%. The kinetic study was found to follow pseudo first order reaction with high correlation. Thermodynamic consideration reveals that adsorption of ethanol extract of Dialium guineense leaves on mild steel surface is exothermic, spontaneous and fitted the Langmuir adsorption isotherm. The value of activation energy and Gibb’s free energy obtained were within the range of limits expected for the mechanism of physical adsorption.
