Characterization of isolates from the fish pond water collected from Port Harcourt, in Rivers State, was done using 16S rRNA gene sequencing method to identify their phylogenetic relationship. The presence of the resistance gene was investigated by polymerase chain reaction followed by agarose gel electrophoresis of the amplification products. A total of 10 bacteria were identified, they include Escherichia coli, Klebsiella quasipnemoniae, Morganella morgani, Vibrio parahaemolyticus, Pseudomonas xiamenesis, Staphylococcus sp, Bacillus flexus, Lysinibacillus macroides, Myoides odoratimimus and Chryseobacterium cucumeris. The Lysinibacillus macroides and Vibrio parahaemolyticus were found to be carriers of the CTX-M gene, while Escherichia coli carried the QNRB gene. SHV gene was also found in the Vibrio parahaemolyticus. The resistance gene found in these bacteria can be transferred to other microbes to cause antibiotic pollution which is a major health challenge.

Biomolecules present in plant extracts can be used as capping and stabilizing agents which reduce metal ions or metal oxide ions to metal nanoparticles in a single-step green synthesis process. In this study, calcium oxide nanoparticle was synthesized using Eugenia uniflora leaf extract in order to ascertain its oil sorption capacity. The characterization of the calcium oxide nanoparticle through UV-vis spectroscopy revealed that maximum absorption was obtained at 207nm indicating surface plasmon absorption of calcium oxide nanoparticle. FTIR results of the Eugenia uniflora leaf extract before and after the synthesis of the calcium oxide nanoparticle indicated the absence of the O-H functional group of alcohol with peak at 3306.1 cm-1 and C-C functional group of alkane with peak at 1449.9 cm-1 indicating their responsibility for the reduction and capping of the synthesized calcium oxide nanoparticle. The morphology of the cacium oxide nanoparticle indicated no definite shape with smooth surface on magnification. The XRD pattern showed that the calcium oxide nanoparticle formed are crystalline in nature with average crystallite size of 3.25 to 4.76 nm. Effect of contact time on the oil sorption capacity of calcium oxide nanoparticle revealed highest sorption capacity at a shorter time (20 min). Kinetically, oil sorption capacity of CaO nanoparticle fitted the Pseudo-second-order model with R2 close to unity (i.e. 0.996). Mechanism of sorption is by chemisorption. Therefore oil sorption capacity of calcium oxide nanoparticle proved to be effective especially at low contact time can be used to clean oil polluted water.

Volterra integro-differential equations have many interesting applications such as process of glass forming, diffusion process, heat and mass transfer, growth of cells and describing the motion of satellite. These equations generally appear in many branches of engineering, physics, biology, astronomy, radiology and statistics. In this paper, authors discussed the application of Sumudu transform for handling Volterra integro-differential equation of first kind with convolution kernel. Some numerical problems have been considered and solved with the help of Sumudu transform for explaining the complete methodology. Results of numerical problems show that Sumudu transform is very effective integral transform for handling Volterra integro-differential equation of first kind with convolution kernel.

Volterra integro-differential equation generally appears when an initial value problem is to be converted into an integral equation. In this paper, authors determined the primitive of first kind Volterra integro-differential equation using Shehu transform. In this work, authors have considered that the kernel of first kind Volterra integro-differential equation is a convolution type kernel. Some numerical problems have been considered and solved with the help of Shehu transform for explaining the complete methodology. Results of numerical problems show that Shehu transform is very effective integral transform for determining the primitive of first kind Volterra integro-differential equation.

This paper presents a mathematical model of the telephone and telegraph equations in a transmission line. The flow of electricity in a transmission line was considered. It was observed that waves and wave propagation are ubiquitous in nature and lead to many puzzling questions. For example, why is it that a storm over the ocean sets off a steady swell of small-amplitude waves, but an earthquake at the sea floor can release an enormous flood wave? What produces mirages in the desert? In response to these questions, a great deal of mathematics has been developed to understand and predict the dynamics of light or sound waves the propagation of matter waves, the vibration patterns of elastic bodies, or the peculiar nature of water waves. This paper will provide a guided tour of mathematical wave theory together with physical applications, including the linear wave equation, dispersion and nonlinear waves and solitons. Mathematically one – dimensional heat equations for the flow were derived.

The change in stored drinking water quality in containers calls for concern due to possible build up of biofilm by bacteria which find their way into water. The study aimed at determining the biofilm and virulent properties of associated bacteria. Thus, thirty water samples from some homes were collected, stored and analyzed using spread and streaking techniques to isolate characteristic bacterial colonies on standard media. A total of 29 bacterial isolates belonging to five genera were identified molecularly. The bacteria isolates namely: Bacillus flexus, Chryseobacterium aquifrigidense, Providencia stuartii, Alcaligene faecalis and Providencia rustigianii were obtained. The bacterial isolates with their percentage virulent potential are as follow; Bacillus flexus 100%, Chryseobacterium aquifrigidense16.6% Providencia stuartii 33%, Alcaligene faecalis 66% and Providencia rustigianii 33.3%. All bacterial isolates developed/expressed biofim formation except Chryseobacterium aquifrigidense. Biofilm formation in the interior surface wall of drinking water storage container was also dependent on the nature and type of storage vessel or container used in the home. The virulence factors as exhibited by these potential pathogens have vital role in invading underlying or immune compromised individuals. Thus, the effect in the change of stored drinking water in containers can be mitigated when individuals maintain good personal hygiene and boost their immune system in order to put off the potential of opportunistic pathogens recovered in this study.

The microbial evaluation of drinking water stored in homes have become necessary as the water could be contaminated by pathogens. Questionnaire administration was done, followed collection of one hundred and eighty stored drinking water samples from homes having no toilet/water facilities and homes with toilet/water facilities. Microbial analyses reported a mean and standard deviation counts of heterotrophic bacteria, Salmonella, Shigella, Vibrio, heterotrophic fungi, Staphylococcal, Pseudomonads, fecal coliform and total coliform bacterial as 1.6 ± 5.8 x 103, 2 ± 1.0 x 102, 0 ± 0.0, 1 ± 1.2 x 102, 0 ± 0.0, 1 ± 1.1 x 102, 0 ± 0.0, 2 ± 2.8 x 102, 6 ± 3.2 x 102 CFU/ml respectively for homes with toilet/water facilities, while for homes without toilet /water facilities, the counts were 2.8 ± 9.8 x 103, 4 ± 1.2 x 102, 0 ± 0.0, 3 ± 4.6 x 102, 1 ± 1.2 x 102, 6 ± 8.6 x 102, 0 ± 0.0, 3 ± 1.5 x 102, 1.2 ± 9.2 x 103 CFU/ml for heterotrophic bacteria, Salmonella, Shigella, Vibrio, heterotrophic fungi, Staphylococcal, Pseudomonads, fecal coliform and total coliform bacterial respectively. A total of seventy (70) isolates belonging to five (6) genera namely: Staphylococcus aureus, Vibrio spp, Salmonella spp, Escherichia coli, Klebsiella spp and Candida spp were isolated and identified biochemically. The isolates with their prevalence from water samples from homes with water and toilet facilities are Staphylococcus aureus 34%, Vibrio spp 3.4%, Salmonella spp 20.6%, Escherichia coli 31%, Klebsiella spp 10.3%, and Candida spp 0%, while Staphylococcus aureus 34.1%, Vibrio spp 9.7%, Salmonella spp 21.9%, Escherichia coli 26.8%, Klebsiella spp 4.8%, and Candida spp 2.4% were noted for homes without toilet and water facilities. Thus, stored water is challenged by poor storage containers, unhygienic sanitary practice and ignorance, as the water samples did not meet the WHO permissible bacteriological limits for drinking water. It is recommended that households develop an altitudinal interest in water security through the practice of good hygiene.

The Pout Njouma area is located in the Nyong unit, which is the northwestern extension of the Congo Craton in southern Cameroon. The assessment of iron mineralization in this area is carried out through rock sampling survey. Representative rock samples were analysed by inductively coupled plasma mass spectrometry (ICP-MS) combined with instrumental neutron activation analysis (INAA) technologies to completely characterize the iron- rich rock samples. The Pout Njouma area is made up of magnetite- gneiss, magnetite- quartzite and banded iron formations; these rocks display microband textures and granoblastic microstructures. The mineral assemblages indicate that magnetite- gneiss and magnetite- quartzite have been metamorphosed under greenschist facies conditions, while banded iron formations display the paragenesis of greenschist to amphibolite facies. This iron deposit belongs to the oxide facies, with magnetite and quartz being the common predominant minerals while sericite and limonite occur as accessory minerals. The Pout Njouma iron occurrence exhibits significant concentration of Fe2O3 + SiO2 (95%), relative elevated values of Al2O3 and TiO2 contents, lower high field strength elements (Y, Hf, Sc, Zr) and variation in enrichment in transition metals. Post Archaean Australian Shale- normalized rare earth elements patterns show slight enrichment in light rare earth elements relative to heavy rare earth elements. The Pout Njouma iron deposits have the composition of Fe-sand, and their geochemical signature indicates that low input of detrital materials contributed to the chemical precipitation of their formation. The absence of a large positive Eu anomaly (Eu/Eu* = 1.01-1.54) indicates that an important role of low-temperature hydrothermal solutions contributed to the deposition of the Pout Njouma ion deposits. Pout Njouma area is of low grade siliceous ore (43.19 to 48.49% Fe2O3) corresponding to depleted iron ore (30 to 50% Fe). The Pout Njouma iron deposits derived from Precambrian rocks which were deposited in an oceanic island-arc margin (ARC) setting where conditions were anoxic and fast sedimentation. The average chemical composition of Pout Njouma iron formations is compared with the known BIFs and the result show SiO2 and Fe2O3 enrichment except in Mballam and Mayo Binka where Fe shows significant elevated values compared with SiO2. Also, data show low concentration of Al2O3, TiO2, CaO and MnO, which infers the non-volcanogenic origin.

Volterra integro-differential equation generally appears when an initial value problem is to be converted into an integral equation. In this paper, authors determined the analytical solution of first kind Volterra integro-differential equation using Sadik transform. In this work, authors have considered that the kernel of first kind Volterra integro-differential equation is a convolution type kernel. Some numerical problems have been considered and solved with the help of Sadik transform for explaining the complete methodology. Results of numerical problems show that Sadik transform is very effective integral transform for determining the analytical solution of first kind Volterra integro-differential equation.

Attribute Selection is very important for classification process. This research has been done by doing attribute selection using PSO method (Particle Swarm Optimization) on SVM algorithm (Support Vector Machine). The development of the classification model uses three parameters especially data attribute, influence of the transformation of various kernel function and penalty factor (C) toward the performance of SVM and PSO-SVM classification. The analysis uses five kernels in mySVM library that existed in Rapidminer application namely dot, radial, polynomial, neural, and anova kernel. The training data used in the first model classification development is student interest data at ABC high school on 2013-2014 year academic. The first model is evaluated using accuracy, precision, recall, and auc value test. The first result shows that the anova kernel on PSO- SVM is able to work with accuracy level 99.30% using penalty factor 0.1. The second model has been developed to predict student interest in XYZ high school. The second result shows that PSO-SVM with kernel anova is able to classify students interest with 99.29% accuracy level.

The study was carried out to investigate the benefits and challenges associated with the practices of agroforstry farming in Igabi Local government Area of Kaduna State, Nigeria. Multi- stage in combination with purposive and random sampling techniques were used to select sixty farmers from the study area. Data for the study was obtained through the use of structured questionnaire that were administered to the farmers supported with oral interview of farmers by the researchers. The data collected was subjected to analysis using descriptive stastistics. The results obtained from the study revealed that mal (80.00%) dominated farming activities in the study area. Majority (96.67%) of the farmers were in their active working age group of between 21 and 60 years of age with about 91.67% of the farmers having ability to read and write while 76.67% of the farmers have over 6 years of farming experience. The study also revealed that 66.67% of the farmers are involved in agroforestry practice in the study area with retention of trees on farmland been the most practiced agroforstry type (28.00%) and alley farming been the least practiced agroforestry type(5.00%). The study also revealed that Parkia biglobosa and Vitellaria paradoxa were the two tree species retained on farmlands while Eucalyptus camadulensis was the least grown tree species on farmland in the study area. Income generation (100%), food provision(91.67 %), medicinal purposes (83.33%), source of fuel wood (80%), provision of shade (75%), erosion control (53.33%), fodder for livestock (50%), source of employment (45%), provision of timbers (43.33%), improvement in soil fertility (40%), wind break(38.33%) were the benefits derived from practicing agroforestry by farmers in the study area. However despite of these benefits agroforestry practice is still facing challenges such as lack of farm inputs(86.67%), usage of traditional farm toolsn(80.00%), lack of credit facilities (70.00%), lack of start – up capital (66.67%), scarcity of water(63.33%), high incidence of pests and diseases (60%), lack of awareness concerning agroforestry practice by farmers (55%), problem of land tenure system (36.67%) and poor knowledge about agroforestry practice by the farmers (20,00%). The study therefore recommends that government intervention in the supplying of improved farm inputs should be given to farmers in the study area and farmers are also encourage to form cooperative society to enable them solve problems of lack of start –up capital as well as lack of credit facilities so that they can actively participate in agroforestry practice to combat environmental degradation.

Deployment of sound diagnostic tests remains a crucial component of malaria management, prevention and control in Africa. Rapid diagnostic tests (RDTs) address the need for accurate diagnosis of malaria particularly in resource limited settings. Misdiagnosis which remains too frequent resulting in antimalarial treatment (Oladosu and Oyibo, 2013). Malaria rapid diagnostic tests (MRDTs) have the potential of significantly improving the diagnosis of malaria in developing countries, especially where there is no adequate microscopy service for the diagnosis of malaria or act as a back-up to microscopy for inexperience personnel. However, the absolute reliance of these tests remains a problem due to uncertainty of the quality of the test and lack of confidence since there is no regulation and lack of proper quality control measures on ground (Okangba, 2019a). There are different commercially available MRDTs in the market these include SD BiolineR, which detects the antibodies of Plasmodium falciparum and Plasmodium vivax using recombinant antigen of merozoite surface protein (MSP), Global DeviceR, Paracheck PfR and Wondfo BiotechR detects Pf histidine-rich proteind (HRP2) and CTK BiotechR detects parasite lactate dehydrogenase (pLDH) in all the species of Plasmodium spp. The quality assessment and heat stability of five commercially procured RDTs (SD BiolineR, Global deviceR, ParacheckR, Wondfo BiotechR and CTK BiotechR). The Quality Assurance (QA) was carried by using prepared Quality Control (QC) samples at different parasitaemia dilutions. The MRDTs failed the initial quality control testing (QC), since none had up to 100% positive as recommended by WHO. SD BiolineR had percentage positive of 83.3% while Global deviceR, ParacheckR, WondfoR, and CTK BiotechR had percentage positive of 33.3%, 16.7%, 33.3% and 8.3% respectively. For heat stability testing, the RDTs were stored at different temperatures for 50days: Global deviceR, CTK biotechR and WondfoR were kept at 400C, and 450C, ParacheckR at 450C and 500C, while SD BiolineR was kept at 400C. They all showed a substantial fall in percentage test line positivity. All the MRDTs gave a 0% positivity expect for SD Bioline, which gave percentage positive of 25% at 400C temperatures respectively. The marked decline in the performance of the MRDTs can be adversely affected by the high temperatures to which they were exposed to in a tropical country, manufacturer’s defects, poor storage facility, mishandling in the course of transportation and use of sub- standard materials in production .There is need for proper regulatory body to regulate the manufacturing and importation of RDTs against any unwholesome practice. Also, there is need to consider the importance of stability of diagnostic test during procurement.

Liver is one of the integral organs in human body. Hepatitis B and C are ranked high amongst killer diseases in the world and Nigeria is said to have large number of people unknowingly living with these viruses. One of the outstanding factors is the poor knowledge of hepatitis B and C amongst the general population including students. This study aimed at assessing knowledge of undergraduate students of ATBU, Bauchi regarding viral hepatitis B and C. This was a questionnaire-based study conducted among students in ATBU, Bauchi using pre-tested self-administered questionnaire. A total of 387 students were enlisted in the study. The tools used for data analysis were frequency distribution, Chi-square tests and odd ratio. Statistical package for social science (SPSS) version 25, R and Microsoft excel 2016 were used for data analysis. A p-value of less than 0.05 was considered statistically significant. It was observed that 86.8% ATBU students have good knowledge of viral Hepatitis B and C sadly, 51 students representing 13.2% have never heard about viral hepatitis. It was also discovered that their knowledge about hepatitis B and C do not depend on the demographic variables, considered in the study. 54.5% students did not know their hepatitis B and C status. 69.8% students have inadequate knowledge about the modes of spreads of viral hepatitis B and C. Findings from this study revealed that ATBU students demonstrated high level of awareness of HBV and HCV infections. Thus, 54.5% participants did not know their status. Students who are well informed about hepatitis B and C were 2 times more likely to know their hepatitis B and C status compared to those with poor or no knowledge.

Our aim in this paper is to consider a different type of implicit iteration scheme called Semi-Implicit iteration (SII) scheme and study its strong convergence as well as the stability for a general class of maps in a normed linear space. We establish the rate of convergence and present numerical example which validate that the SII iterative scheme converges better than implicit Mann, implicit Ishikawa iteration and implicit S-iteration schemes.

Kantor Pelayanan Perbendaharaan Negara (KPPN) is the initial gate of services from the finance ministry in Indonesia. To realize good public services, the KPPN is the spearhead of service to customers at the regional level. Therefore customer satisfaction is very dependent on the quality of service at KPPN. This study aims to analyze the influence of organizational culture and human resources on customer satisfaction in service at KPPN Sibolga City. This study used an online survey method with an explanatory approach. The population of this study is the employees or staff in the work unit in the Sibolga KPPN area, the sample of this study was 56 respondents determined using the Slovin formula. Data analysis uses multiple linear regression test. The results showed that organizational culture p = 0.001 (p <0.05), and human resources p = 0, 002 (p <0.05) affect customer satisfaction in KPPN Sibolga City. Organization Culture is the most influential factor on customer satisfaction in KPPN Sibolga. KPPN must maintain the organizational culture that has been built so far for customers by applying standard operating procedures that are evaluated regularly, so that the culture that is built becomes a system that can be developed and duplicated in other places.

On January 30 2020 the World Health Organization (2020) declared the novel coronavirus outbreak (COVID-19) a global public health emergency of international concern. This paper examines the effect of COVID-19 pandemic on consumption of telecom products in Nigeria. Secondary data from the financials of MTN Nigeria Communications Plc and telecommunication (Telecom) industry reports the National Bureau of Statistics (NBS) were analyzed. From the review of available data, the author establishes that the consumption of telecom services in Nigeria increased during the period of the first quarter of 2020 which was the period which coincided with the lockdown of the economy. The paper recommends that a similar study is carried out for the period up to June 2020 to determine if the consumption pattern observed for the earlier part of the years persists.

Groundnut oil is an organic material oil derived from groundnuts and it has been noted to have the aroma and taste of its parent legume. The study therefore produced biodiesel crude groundnut oil through alkali catalyzed transesterification using methanol, in the presence of Sodium Hydroxide (NaOH). The physiochemical parameter of biodiesel was characterized and from the results obtained, the methyl ester produced can be effectively used in a diesel engine since the value is within the range of the required standard. Groundnuts oil has biodiesel optimum yield of 93.9% and the fuel properties of the biodiesel are close to that of petroleum diesel and hence can be used as alternative fuel.

Evaluation of yield and spoilage moulds of Pleurotus ostreatus grown on sawdust, wood ash and cassava bran were conducted in the Department of Plant Science and Biotechnology and Dilomat Farms and Services Limited, Rivers State University. The three substrate materials were subjected to different concentrations and mixtures. A total of ten treatments were formulated including the control containing only sawdust and a combined effect containing all the substrate materials. Yield parameters assessed were height of fruiting body, length of stipe, width of stipe, length of pileus, diameter of pileus and weight of harvest. Sawdust and cassava bran (SCB) treatment had highest height of fruiting body (11.50±1.41). Equal diameter of pileus (6.25±1.06) was recorded for both combined effect (CE) and SWA treatments. However, equal values of pileus length were recorded for both CE and sawdust and wood ash (SWA) treatments. The control treatment had highest values for length of stipe, width of stipe and weight of harvest. Four fungal organisms viz: Rhizopus oryzae, Aspergillus flavus, Fusarium oxysporium and Trichoderma harzianum were found to contaminate the experiment bags. R. oryzae and T. harzianum had equal incidence of 27%. This was followed by 24% incidence recorded for A. flavus. Lowest incidence of 22% was observed for F. oxysporium. The deteriorative activities of these isolates affected the development of higher concentration levels of sawdust and cassava bran treatments as there was no harvest recorded for these treatments due to contamination. Generally, the control treatment performed better than other treatments used.

COVID-19 is a disease caused by the novel coronavirus that was reported in China in 2019. The virus has infected more than a million people globally leading to hundred-thousands of deaths. Hence, forecasting the future confirmed cases to support prevention of the disease and aid in the healthcare service preparation is very important especially in developing countries. In order to support governments’ effort in the prevention of COVID-19, we developed an ARIMA model which was used in forecasting future COVID-19 cases in selected West African Countries. The forecasting results from this study indicates an increase cases in the coming days. It is expected that the present prediction models will assist the government and medical personnel in the selected countries to be prepared for the upcoming conditions and have more readiness in healthcare systems.

Accurate breast cancer screening is essential to ensure patient with such symptom can be treated accordingly. Medical screening is quite complicated since every patient sign and symptoms will be screened and when the number of features increases the medical practitioner will not able to be screened appropriately. 3Satisfiability Reverse Analysis Method (3-SATRA) incorporated with Hopfield neural network is a new approach for the early detection in breast cancer medical dataset. 3-SATRA has proposed to extract the best logic rule that will representing the attribute of breast cancer dataset since the conventional data extraction techniques focus only on standalone neural network. The proposed method is applied to Breast Cancer dataset obtained from UCI machine learning repository. To pursue that, the results of the analysis will promote the early detection stage used for medical practitioners. The simulation will be executed using Dev C++ 5.11 as a tool for training, testing and validating the performances of the proposed method. The performance of the method was measured based on Root Mean Square Error (RMSE), Mean Absolute Error (MAE), Sum of Squared Error (SSE), and Computational Time. The performance and accuracy of the results obtained have shown the effectiveness of 3SATRA in medical data mining.

With the increase in the number of student population, new programs being attached, an automated time-tabling system is required to cater for this increase. Most of the time-tabling problems belong to the class of (Non Polynomial) NP-hard problems, as no deterministic polynomial algorithm exists. Timetable definition is the total schedule of specific lectures attended by a group of students in an institution and the lecturers at a specific time. When solving the timetabling problem, we are usually looking for some solution, which will be the best among others. The space of all feasible solutions which is the series of desired solutions with some more desirable than the others is called search space (also state space). Each point in the search space represents one feasible solution which can be “marked” by its value or fitness for the problem. The solution is usually one point in the search space. This research centers on the utilization of computerized system concerning electronic planning and exam booking control arrangement in tertiary Institutions. The work conquers the manual arrangement of activities with respects to the issues timing and planning. The work was effectively evolved utilizing python structure, SQLite Database. Client experience was utilized, an easy to use programming language, and the bundle was tried and enhanced to yield a mechanized Time table plan booking control framework
