This work investigated the dynamics of coronavirus amongst the susceptible individuals. It is established herein, with a proposition that there exists a control strategy that is bounded above by 0.01 for the contact rate of susceptible individuals. It is observed that at a=d=1.5, the virus population and the human population coincides, however, at c=b=0.1, almost all the human population is infected by the virus. It is also observed that at endemic state, the corona virus population experienc...
ABSTRACT Industrialization and urbanization has increased tremendously in the last few years, especially in underdeveloped countries, such as Kenya. This has resulted in rising demand for certain aesthetic goods such as paints and coatings. Paint and coating industries use extensive raw materials in their manufacturing processes that consist of heavy metals, various solvents, and organic compounds. The wastewater released from these industries contains residual chemicals that are highly ...
Have you ever wondered how your hormones levels affect your growth and development into adulthood and beyond? How about how your bodily systems affect sleep and metabolism? This is all your endocrine system in play. Your endocrine system is responsible for regulating your growth, sexual development, mood, sleep, and numerous other biological functions that power your day to day routine. Endocrine cells in the body release hormones that bind to target cells of your body after traveling through...
In this articleootnote{https://debuggercafe.com/reducing-image-distortion-using-spatial-transformer-network/}, we will learn how we can reduce distortion in images using the Spatial Transformer Network (STN) using the PyTorch deep learning library. Figure 1 shows the results of applying STN to the distorted MNIST dataset. After applying STN to the distorted images, we can see that the images spatially more plausible and readable. If you are new to the topic of Spatial Transformer Networks, t...
Abstract Technology is a never-ending process. This paper presents a low-cost flexible and reliable home automation system with additional security using ESP32 Development Board, with IP connectivity through local Wi-Fi for accessing and controlling devices by authorized user remotely using Android Smartphone application. The proposed system is server independent and uses Internet of things to control human desired appliances starting from industrial machine to co...
Abstract This study was conducted to determine the level of fruits and vegetable contamination with medically important geohelminths and gastrointestinal protozoan parasites in Oyi Local Government Area. A total of 600 fruits and vegetables were purchased from the daily markets located in five communities in the study area in the morning hours from 7:00 am to 10:00 am. They were washed with saline water and examined microscopically for helminths and gastrointestinal protozoan parasites by sed...
Abstract The research was carried out on the floral composition of Neni-Nimo watershed between November 2019 and July 2020. The research work aimed to find out the various plant species that inhabit the watershed, their abundance measures and importance values. In this study, the watershed was divided into three catchment areas, the upper, the middle and the lower catchment. Each of the catchment zones was divided into component parts, with an area of (50 m X 30 m) each. The experiment was la...
Abstract The antimicrobial resistance or otherwise of Coagulase-negative Staphylococci (CoNS) isolates from medical students of some South Eastern Nigerian Universities were determined. Swab samples were obtained from the students and were cultured for CoNS using standard microbiological methods. Isolates obtained were assayed for antibiotic resistance using disc diffusion method. MecA and blaZ genes on 533bp and 510bp respectively, of the isolates were amplify using the Polymerase Chain Reac...
Selection of prospective candidates to a higher institution of learning based on candidate’s choice of course of study is now becoming a herculean task, particularly when the carrying-capacity of two hundred and fifty–six higher institutions in Nigeria cannot admit over one million eligible candidates seeking admission yearly. Several works have been done in the past using Nave Bayes algorithm, Decision trees, K-Means algorithm, Random Forest and other Machine learning algorithms to predi...
Gradient descent method is commonly used as an optimization algorithm for some machine learning problems such as regression analysis and classification problems. This method is highly applicable for real life of yearly demandprice commodity, agricultural products and Iris flowers. This study proposed the combination of Dai-Yuan (DY) and Saleh and Mustafa (SM) conjugate gradient methods for the optimization of supervised machine learning problems. Experiments were conducted on combined DY and ...
Abstract Weight loss and Density Functional Theory (DFT) methods were used to study the corrosion inhibition of 5-methyl-2H-imidazol-4-carboxaldehyde and 1H-Indole-3-carboxaldehyde on mild steel in acid medium. The values of thermodynamic parameters such as free energy of adsorption (ΔGºads), adsorption equilibrium constant (Kads), adsorption entropy (ΔSºads), adsorption enthalpy (ΔHºads) and activation energy (Ea) were calculated and discussed. The adsorption process on mild steel surf...
Abstract Poor animal health is a major problem limiting livestock productivity in sub-Saharan Africa including Nigeria. Decline in funding veterinary services, animal health and cost of veterinary medicines and services have pushed poor, rural farmers to search for alternative medicine. Ethnoveterinary medical practices play important roles in animal healthcare system in Nigeria. This work was done to provide information on some medicinal plants that are used to treat animal diseases in Niger...
Abstract An investigation was carried out on the plasmid profile of Streptococcus lactis and Lactobacillus plantanum isolated from a total of 120 samples collected from Oyingbo, a local market in Lagos State. Morphological, cultural, physiological characterization and API kits were employed to isolate and identify and treptococcus lactis and Lactobacillus plantanum. All the isolates harboured plasmids ranging from 1-7 in numbers and 3kb – 21.5 kb in sizes. Distinct plasmid patterns were...
ABSTRACT This work assessed the probiotic potential of “Nunu” using Lactobacillus, a genus of Lactic acid bacteria and a major probiotic organism as the indicator. The viable Lactobacillus counts of samples purchased from six different areas within Lagos Mainland were enumerated by serial dilution and pour plating in selective media, DeMann, Rogosa and Sharpe agar (MRS). Twelve strains of Lactobacillus were randomly selected from the samples and identified by standard morphological, physi...
ABSTRACT The effectiveness of cotton seed dextrose agar, groundnut seed dextrose agar and kernel dextrose agar in culturing fungi was studied by culturing fungi from yam rot (Dioscorea rotundata). The research demonstrated the choice of the isolated fungi to various media, and revealed that some of the isolated fungi showed the same occurrence in different media. Aspergillus flavus showed preference for kernel dextrose and groundnut seed dextrose agar than Sabouraud dextrose agar and cotton s...
