Methylene Blue (MB) was adsorbed from aqueous solution using Baobab (Adansonia digitata L.) fruit pod and its goethite modified form. Adsorbents were characterized using Fourier Transform-Infra Red (FTIR) spectroscopy and Scanning Electron Microscopy (SEM). Batch experiments were conducted at room temperature (26.8 °C) and the adsorption data were fitted using Langmuir, Freundlich, Temkin and Dubinin- Radushkevich isotherms. Also, kinetic data was fitted using Pseudo-first order, pseudo-second order, Elovich and intra-particle diffusion models. Goethite modified baobab (GMB) appeared to have a coarse microporous surface with smoother surface and larger pore volumes compared to unmodified baobab (UB). The –C=O band was observed at 1631 and 1636 cm-1 for UB and GMB. The –OH band was observed at 3447.00 cm-1 and 3442 cm-1 for UB andGMB respectively. Langmuir model was suitable for describing the adsorption data of UB with R2 of 0.9293 while Temkin model was best for fitting adsorption data of MB on GMB with R2 of 0.9691. However, maximum adsorption capacity was obtained with Freundlich adsorption isotherm (15.4253 and 43.1301 mg/g for UB and GMB respectively). The maximum biosorption were 8.98 mg/g and 9.86 mg/g for UB and GMB respectively at pH 10. Pseudo-second-order kinetic model best fitted the kinetic data with R2 values of 0.9968 and 0.9993 for UB and GMB, ΔHo values were 83.123 KJ/mol and 361.094 KJ/mol for UB and GMB, while ΔSo values were 3.084 J/mol/ K and 1.765 J/mol/K for UB and GMB respectively. GMB adsorbed more of MB than UB and the process was endothermic.

Published: August 2020

Soil microrganisms or faunas play vital roles in biogeochemical cycles which maintain the state of equilibrium of mineral elements in soil ecosystem as well as impacting on its texture and structure in otherward productivity. The impact of herbicides on biological population of soil samples spiked with various herbicides such as: dragon (paraquat) dichloride, Action 40 (Dimethoate), Vanish (Glyphosate). Buta force (Butachlor) and Amino force (2, 4-D amine 720G/L) were investigated. The soils were spiked with 10% of the herbicides, incubated for 4weeks and the oxidative stress as well as the acetylcholinesterase activity of soil faunas used as biomonitors. There was a progressive increase of lipid peroxidation in achatina achatina with vanish having the highest level of malondialdehyde (5.12 mg.dl) and dragon herbicides with the lowest levels on the second week (2.67 mg/dl). The sample contaminated with amino force herbicide had the least impact on glutathione levels (1.66 mg/dl) while the dragon herbicide depleted more of the glutathione levels (1.31 mg/dl). The Achatina achatina incubated with the soil sample spiked with vanish registered the highest catalase activity (6.2 1U/L) while action 40 recorded 3.9 IU/L as the least activity. Acetylcholineesterase activity seen in Achatina achatina incubated with soil sample 4(vanish) was inhibited beyond all other samples with 0.169 IU g protein-1 as the least value with the exception of amino force that depreciated to 0.108 IU g protein-1on the third week. This study reveals how detrimental these herbicides can be to achatina achatina which counsels the farmers on their selectivity for agricultural purposes.

Published: August 2020

The present study investigates household consumption pattern of snail meat in Oluyole Local Government Area of Oyo State. A multistage random sampling technique was used to administer the questionnaires to a total of 120 respondents. Data collected were analyzed using both descriptive statistics and inferential statistics. The socioeconomic factors analyzed showed that age group between 31 and 40 (45.0%) consumed snail more while age group between 51 and 60 (11.70%) consumed less snails. The majority of respondents were Married (60.8%) and possess secondary education (54.2%). Most of the respondents (95.8%) consume snail meat but most of them consume snail meat on a seasonal basis unlike beef and fish. Furthermore, fried form of snail meat is mostly (65%) preferred when compared to cooked form (24.2%). The regression analysis shows that the consumption of snail meat depended on the price, household size, educational level, household income, nutritive value, occupation and its availability. Problems associated with snail meat consumption in the study area include Price, income level, unavailability and cultural belief. Based on the findings, this study recommends that extension workers should engage the public on the need to get involved in the rearing of snails to make it readily available all year round and thus make it more affordable for all sundry.

Open Source Automation Software: Stirring Automated to Integrated Library System
Authors: Moruf H.A. , Sani S. , Abu Z.I. 
Published: August 2020

The explosion of the World Wide Web; dynamic nature of information technologies, such as open source; the increase in electronic resources; and the rising expectations of library users have contributed to the changing nature of the Automated Library System (ALS) since its inception in the 1970s. These changes are reflected in the conceptual differences between the ALS and the Integrated Library System (ILS). The ALS is identified as simply a database to house and retrieve a library’s holdings while ILS is identified as robust clusters of systems involving every process and module related to library operations. This article presents a review on the evolving features of some commonly adopted Open-Source ILS Software (Koha, NewGenLib, Evergreen, PMB and OpenBiblio) which had stirred ALS to ILS, as well as justifications and barriers to the use of open source software in academic libraries.

Published: August 2020

Malaria in pregnancy is a major public health problem affecting women fetuses and new borns. Many studies highlight the critical importance of continuing the use of Insecticide Treated Nets (ITN) and Intermittent Preventive Treatment In Pregnancy (IPTp) among pregnant women to reduce the adverse consequences of malaria in pregnancy. This study was conducted in order to determine malaria prevalence in relation to the use ofITN and IPTp among the pregnant women in the study area. Five (5) ml of blood was obtained from each participant by the use of a sterile syringe and placed in a sterile EDTA container for laboratory analysis. The malaria parasite was detected by microscopic examination of Giemsa-stained thick blood films. Information on the use of ITN and IPTP was collected using administered questionnaire. A high prevalence of 78.4% was observed among the studied population. Although 74.4% of those that use ITN were positive for malaria parasite as against the 83.6% of those that reported not using the ITN, the difference was statistically not significant (p<0.05). 70.0% of those reported using IPTp were positive however, higher percentage was observed for those reported not using IPTp (83.7.0%). The difference was statistically significant in this case. This study has shown the influence of malaria prevention method during pregnancy on malaria infection and the need for targeted preventive starategies when designing and implementing policies aimed at improving uptake of these measures during pregnancy in Gombe.

Published: August 2020

This study assessed the concentration of selected heavy metals (Lead and Zinc) from surrounding soil of Royal Salt mining company, Enyigba in Abakaliki LGA, Ebonyi State. Soil samples were collected from nine (9) different locations at depths of 0-15 and 15-30cm. Two (2) samples were collected from each of the nine locations, making it total of eighteen (18) samples. Soil analysis carried out were particle size distribution, pH, available Phosphorus, total Nitrogen, Organic Carbon, organic matter, Calcium, Magnesium, Potassium, Sodium, exchangeable acidity, Aluminium, effective cation exchange capacity, base saturation and two selected heavy metals, Lead (Pb) and Zinc (Zn). Results shows that heavy metals were highest in soil around the disposal site of mine waste. The highest value of Pb and Zn was recorded on tailing down (TD) 14.82 and 25.33mg/kg at 0-15cm depth, 7.22 and 18.93mg/kg at 15-30cm depth respectively. The accumulation of Pb and Zn at the mining site (TD) may be due to mining activities, civil, industrial/anthropogenic activities going on around the site. This study recommends regular monitoring of heavy metal concentration in soil within the mining site and their disposal site in order to conform to international standards set by the WHO.

An Implementation Of A Repository For Healthcare Insurance Using MongoDB
Authors: Yange ST , Gambo IP , Ikono RN , Onyekwere O , Soriyan HA 
Published: August 2020

The explosive growth of unstructured data in the National Health Insurance Scheme (NHIS) in Nigeria has given rise to the lack of an appropriate data storage mechanism to house data in the Scheme. This paper x-rayed these data storage challenges with a view to implementing a storage mechanism that can handled large volume and different formats of data in the Scheme. The NHIS is currently using the paper-based, file and cabinet data storage system with some of the data stored in the form of PDF, Excel and image files on the computer system. This has led to serious challenges ranging from the loss of data, lack of appropriate data storage facilities to accommodate the data to the delay in the administration of quality care to beneficiaries of the Scheme. Also, the diversity of data with the ever-growing datasets which is also generated at very high rate has also constituted a major challenge for NHIS. This research therefore developed a computer-based data storage system using MongoDB which has full index support, replication, high availability and auto-sharding. The design was done with Enterprise Application Diagrams and implemented using Java Programming Language, MapReduce Framework and MongoDB. The study shows that there are inequities in the delivery of services within the NHIS in Nigeria due to lack of proper storage medium. This is responsible for the ineffectiveness and inefficiency of healthcare services received through the Scheme. In conclusion, this research has provided the stakeholders with access to information more easily, which will enable them to plan, evaluate, and collaborate more effectively.

An Empirical Study into Comparing Conventional and Islamic Banks in the UAE
Authors: Kapur Manoj 
Published: August 2020

Banking system constitutes the fundamental pillar of every economy. Banks acts financial intermediaries between sectors that have excess funds and those that are in deficit. Islamic banks operate under Sharia principles of risk sharing and interest prohibition as contrasted with conventional banks that buy capital to pool funds and sell capital to generate interest income or profit. This paper applies banks’ internal factors related to their balance sheet and income statement and using a total of 23 financial ratios pertaining to the internal factors, it attempts to compare and contrast between conventional and Islamic banks. This research explains the structure, operation and management of banks in the UAE coupled with the functioning of Islamic banks. The paper also aims to determine the profitable and efficient banks among the chosen sample. The sample includes 12 banks, equally distributed between Islamic and conventional banks using data between the periods of 2014 - 2018. The sample is broadly categorized based on profitability ratio, efficiency ratio, asset indicator ratio and risk ratios. Correlation and Regression analysis is used to determine a substantial ratio analysis between conventional and Islamic banks. Results from the study reveal indicators of financial characteristics such as profitability ratios, efficiency ratios, asset quality indicators and risk/ risk management ratios. The results clarify that Islamic banks are operationally efficient and profitable because of risks sharing and greater dependency on deposits capital. However, on an overall basis, the ratios indicate conventional banks have higher scores than their counterparts.

Published: August 2020

We report a unique case of prolonged acute rhabdomyolysis in a 2-year-old male with known TANGO-2 mutation with delayed peak in creatinine kinase levels secondary to human metapneumovirus infection. Creatinine kinase peaked at 424,760 U/l on day 9 of hospitalization. Resolution of rhabdomyolysis was achieved using aggressive management with intravenous fluids with optimal urine output and no kidney injury. TANGO-2 patients may develop severe and prolonged rhabdomyolysis with a delayed peak suggesting the need for prolonged inpatient hospitalization to prevent life-threatening complications.
