Kaolin is used in industries because of unique physical and chemical properties, shapes, particle size, color, soften and non-abrasiveness are physical properties that are specifically important. Beneficiation of Ahoko Kaolin was performed in an air cyclone and characterized using XRD, XRF AND SEM. X-ray fluorescence performed on both raw and beneficiated Ahoko Kaolin was determined, from XRF result the raw Ahoko Kaolin contained Al2O3 and SiO3 contents of about 14.47 wt % and 73 wt% respectively, and after beneficiation of Ahoko kaolin, the Alumina contained was improved from14.47 wt% to 17.57 wt%. The XRD result shows that Ahoko Kaolin contains some impurities such as quartz, Nosean, Illite garment. The result shows that there is a decrease in the amount of quartz in beneficiated Kaolin with the value range of 42% to 33.3% and the Alumina content increase from 39% to 64% which make it more significant and easy for industrial use. The SEM analysis of raw and beneficiated Kaolin shows the morphology study of both raw and beneficiated Kaolin which indicated that the flits present in the raw Kaolin is less compare to the beneficiated Kaolin, so, therefore. The beneficiated Kaolin will be more convenient and suitable for industrial use.

Information and communication technologies (ICT) have become commonplace entities in all aspects of life. Across the past years the use of ICT has fundamentally changed the practices and procedures of nearly all forms of endeavour within business and governance. Education is a very socially oriented activity and quality education has traditionally been associated with strong teachers having high degrees of personal contact with learners. The use of ICT in education lends itself to more student-centered learning settings. But with the world moving rapidly into digital media and information, the role of ICT in education is becoming more and more important and this importance will continue to grow and develop in the 21st century. ICT helps in improving the quality of education stating that information and communication technology is an important instrument that can transfer the present isolated, teacher- centered and book-centered learning environment into a student –centered environment. ICT can change the traditional concept of learning process and the components of ICT should be integrated in the education programme in such a way that teaching should be enabled to face the new demands and improve the efficiency and effectiveness of education at all levels in both formal and non-formal settings. Thus, we must accept the new paradigm and technology in teaching learning process. Educational institutions need to develop strategies, plan to improve teaching-learning process and ensure that all teachers are well prepared to use the new tools for learning. The emergence of the knowledge-based society is changing the global status of education. Now it is the time to develop a new knowledge-based global society. In developing countries like Nigeria, there are many untrained teachers in this area. The new ICT would be able to reach these teachers and can provide quality education all around the globe.

In this study, activation of peroxymonosulfate (PMS) by biochar derived from rice husk (considered useless agriculture wastes) toward organic pollutants from aqueous solution was investigated. the basic properties of biochar were characterized through scanning electron microscopy (SEM) g PMS concentration and elemental analysis (EA). Operating parameters including PMS concentration, dose off biochar and initial concentration of target pollutants (Salicylic acid (SA) and Sulfosalicylic acid (SSA)), were systematically studied. The result showed that biochar derived from the rice husk effectively activated of PMS, leading to high degradation of organic pollutants in aqueous solution. The degradation efficiency of organic pollutants increased with increasing PMS concentration and amount of biochar. The reusability of rice husk biochar and the possible mechanism for PMS activation was proposed accordingly. These findings suggest a novel rice husk for activation of PMS toward toxic organic pollutants from waste water.

The acceptability of information technology in practically every accept of industry, organization, public and private sector has brought a drastic transformative changes in all human aspects where farming and cultivation are not eluded. The rate by which farming is growing from traditional form to the mechanized farming through the use of technological tools and machines is beyond explanation. However, lesser attention has been given to solve the major problems faced with agricultural sector in Nigeria in the areas of financial support to farmer, market access to the buyer and challenges of transportation. Although, some AgriTech companies in Nigeria such as Farmcrowdy, Farm4me, Piggyvest etc. have tried solving some of these problems but still unable to proffer solution to the issue of marketing, Customers-Farmers Interaction (CFI), and transportation that have discourage farmers from producing more for the fear of getting potential customers or buyers. This study adopted strategy called Customers-Farmers Interaction Framework (CFIF), where we designed a robust website that serves as a mobile digital platform called Farmseed that brings potential buyers closer to the farmers by accommodating the farmers, the potential buyers, logistics, funds etc. Some information about the farm produce and as well as information about the buyers were gathered majorly from online. This innovative idea yields positive acceptability and cater for the most challenging issues of marketing, customers-farmers-interaction and transportation.

Department of Computer Science, Abraham Adesanya Polytechnic, Ijebu-Igbo, Ogun State, Nigeria.
Prediction of Electorate Sentiments (ES) in the Nigeria Political System is intriguing research but, it is associated with several difficulties because it is hard to recognize sarcasm during the election campaign and detect the sincere view of the electorate. Sometimes, the negative sentiments of electorate were viewed as sincere facts, and positive sentiments were viewed as false information by the political parties due to the campaign strategy of the politicians. Therefore, this study aims to build a model for evaluating the correlation between electorate pre and post-election sentiments and Independent Electoral Commission (INEC) results in the 2021 governorship election in Anambra State, Nigeria. A primary dataset was gathered from the Twitter Micro-blogging website, which comprises four-month data from August 4, 2021, to November 30, 2021. Python Anaconda was used to implement the study. A text-blob and Natural Language Took Kit (NLTK) were used to detect the polarity of the Twitter sentiments. Extra Tree and Gradient Boosting (GB) models were evaluated to predict the polarity of ES. The result evaluation showed that the GB classifier is efficient when implemented with lemmatized tweets showing 0.77 accuracies for the pre-election and 0.50 accuracy for the post-election tweets. The frequency of the word cloud for the positive and negative sentiments shows that Electorate Sentiments correlate with the outcome of the election as declared by INEC. Also, the result obtained from the evaluation of the machine learning models showed that GB is efficient for predicting Twitter sentiment.

Snacks are simple, between-meal foods. Processed snacks are more durable and portable than prepared meals. Street food is contaminated by unsanitary sellers. Aspergillus species produce aflatoxin B1 in grains and oilseeds. Hepatocellular carcinoma is linked to long-term aflatoxin B1 exposure. Aflatoxin B1 and fungus species levels in sausage rolls sold within Kaduna state were examined in this study. Forty (40) sausage roll samples were gotten from four (4) local governments within Kaduna state. The samples were analysed for moisture content, Aflatoxin B1 assay and mycological analysis using standard microbiological methods. Aflatoxin B1, moisture content level, mould loading, and distributions were analysed using descriptive statistics. Egg rolls and meat pies from the streets and supermarkets had the highest moisture content, while plantain chips had the lowest. Street snacks in Kaduna South had 5.4 x 104 cfu/g, whereas supermarkets in Kaduna North had 1.75 x 104. Aspergillus niger (18.8%), Aspergillus flavus (16.0%), and Mucor (16.0%) were detected in streets sausage roll samples. Fusarium sp. had 6.0%. Supermarket samples had similar percentages. Aspergillus flavus, niger, and Mucor had the most (23.1%). Fusarium sp., Penicillium, Yeast, and Rhizopus recorded 7.7% each. Street snacks differed significantly from supermarket snacks. Kaduna South street snacks had 13.69g/g of aflatoxin B1, whereas Igabi supermarkets had 5.2g/g. The study showed that street-vendor snacks were substandard to supermarket snacks, with the Aspergillus family being the most common fungal isolates to ensure snack safety, food manufacturers and hawkers must maintain a clean environment, minimise contact with food samples after manufacturing, and expose sellers and customers to certified training sessions. This will help curb the incidence of food infections related to consumption of contaminated snacks.

The rating of carbon black as carcinogenic by IARC under classification 2B and the high cost of carbon black filler derived from petroleum resource has necessitated a search for alternative reinforcing fillers for the rubber industry that are cheap,renewable,non-toxic and abundant in nature. More so, reckless burning of expired automobile tires and other rubber products and their disposal at refuse dumps without any means of biodegradation pose serious environmental disposal problems in recent times. In view of the above, starch was extracted from Polynesian arrow root (amora), Tacaleontopetaloides (L) Kunze and its particle size, pH, amylose, amylopectin composition determined. A starch /natural rubber composites was prepared by directly mixing and co-coagulating rubber latex and gelatinized starch with an aqueous electrolyte, and thereafter compounded in a two-roll mill according to American Society of Testing and Materials(ASTM) ,D3184-80.The starch/natural rubber blend was cured by sulphur vulcanization and accelerators method. The trial batch starch fillers revealed that the optimum volume percentage for filler addition is in the range of 20-30 part per hundred rubber(pphr). The starch/natural rubber composites were subjected to microbiological activity by isolated Bacillus megaterium, Bacillus sp. and Pseudomonas aeruginosa in a mixed culture. The starch/natural rubber composites were used as the sole source of carbon and energy using mineral salt medium (MSM) procedure under closed system. Biodegrdation activity was found to be at maximum with sample Fo (cured rubber without starch filler). From the results, amora starch when uploaded at 30pphr can partially replace carbon black as natural rubber filler with reduced production cost and health risk pending further investigation.

Mycobacterium bovis still remain the major pathogenic species to humans and bovines, despite the efforts made to eradicate it. This study was carried out to assess milk and milk products sold across north central zone of Nigeria. A total of nine hundred (900) samples were collected randomly from three states. Samples that were used for mycobacterial count were not refrigerated but directly taken to tuberculosis laboratory for analysis. Method of digestion and decontamination of samples followed by cultured on Löwenstein-Jensen medium enriched with egg and glycerol (L-J-G medium) and Stonebrink medium using pour plate method were imbibed. The cells that suggest the growth of mycobacteria were examined microscopically after modification of Ziehl-Neelsen staining for acid-fast bacilli. Findings revealed the mean count of mycobacterium obtained from Niger state range from ND to 3.40 Log cfu/mL with highest count observed in Agaie LGAs. Mycobacterial count of nono ranged from ND to 3.45 Log cfu/mL. This study revealed there was significant differences (P<0.05) among the mean mycobacterial count of milk products sampled. Mycobacterium isolated includes; Mycobacterium tuberculosis strain LJ319, Mycobacterium tuberculosis strain LJ319, Mycobacterium tuberculosis strain MNPK, Mycobacterium avium strain Marseille, Mycobacterium fortuim strain M213 and Mycobacterium bovis strain: GTC 602. However, Mycobacterium bovis had highest frequency of occurrence (38%) for fresh milk and 35.4% for nono. The introductions of milk pasteurization and tuberculin (ppd) positive cattle eradication programs will greatly reduce the incidence of human and bovine tuberculosis.
