Enhanced Brain Tumor Image Classification Using Convolutional Neural Network with Attention Mechanism

Detecting brain tumors early is crucial for precise diagnosis and the development of effective treatment strategies, given the severity of the condition involving the uncontrolled growth of abnormal cell clusters in the brain.This research introduces an innovative Convolutional Neural Network (CNN) model augmented with an attention mechanism for the classification of brain tumor images, utilizing a comprehensive dataset of 3,000 Magnetic Resonance Imaging (MRI) scans sourced from Kaggle. Rigo...

Computational biology in proteomics

The broad application of proteomics in different biological and medical fields, as well as the diffusion of high-throughput platforms, leads to increasing volumes of available proteomics data. Computational proteomics is the data science concerned with the identification and quantification of proteins from numerous data and the biological interpretation of their concentration changes, posttranslational modifications, interactions, and subcellular localizations. Computational proteomics is a h...

Detection of Extended Spectrum Beta-Lactamase Production in Escherichia coli Isolated from Cattle Faeces in Owo Metropolis

Escherichia coli which synthesize extended spectrum beta-lactamases (ESBL) have been implicated in severe human diseases. There is substantial evidence that cattle faeces have a role in developing and spread of multidrug-resistant pathogens, raising public health concerns. The study is aimed at detecting ESBL-producing E. coli associated with cattle faeces within Owo metropolis. Freshly passed faecal samples were taken aseptically from 9 apparently healthy cattle that were about to be sl...

Preparation of natural dyes from different plants as photosensitizer in modified SnO2 photoanode films for dye sensitized solar cell application

Abstract  The study focuses on the potential of naturally occurring dyes as photosensitizers in dye-sensitized solar cells (DSSCs). DSSCs are a type of solar cell that uses chemicals called photosensitizers to absorb energy from visible light and produce excited electrons. In 1991, Grätzel and his co-workers developed DSSCs, which have gained attention in recent years. However, the ruthenium-based compounds used as photosensitizers are expensive, and research suggests that organic dyes ...

Analysis of Simple Sequence Repeats Marker (MK190) Dervided in Capsicum Chinense JACQ. Transferability in Two Pepper Species and Diversity of Fruit Placenta Length and Type

The genus Capsicum ( sweet and hot pepper) is an incredible intra and inter-specific diversity in fruit type, color, shape, taste and biochemical content. Molecular biology techniques based on DNA analysis are being adopted in the modern study of plant breeding. The aim of this study was to assess the applicability of SSR techniques in transferability assessment and diversity of placental length and type in genus Capsicum . This study analyzed 19 accessions of Capsicum species obtained from d...

The Statistical Analysis on Road Traffic Accidents in Nigeria

ABSTRACT  Biologically, every living thing has a general property. One of these properties is movement. As a result of this movement, some hazard can occur. One of these hazards is accident. Generally, in Nigeria, the major mode of movement is by road. Road accident has become a major threat to lives of citizens of the country especially during the festive period. The increasing magnitude of fatal road traffic accident globally has been attributed to population explosion and increased leve...

A Mathematical Model for the Control of Ebola Virus Disease in Nigeria

Ebola Virus Disease is one of the deadliest infectious diseases that has increased both mortality and morbidity rates primarily on the African continent. The aim of this report is to use mathematical modeling and analysis in controlling the spread of this disease. In this study, a mathematical model which represents the transmission and control processes of Ebola Virus Disease among human and vector hosts is developed. The Well-Posedness, Equilibrium States (i.e Disease Free Equilibrium and E...

Synthesis and Characterization of Transition Metal Complex with Pyridl Based Schiff Base as Ligands

Abstract The pyridyl based Schiff base ligands from 2-aminopyridine and benzaldehyde and 2-aminopyridine and 2, 4-dihydroxylbenzaldehyde were synthesized by: 1. For Schiff base from 2-aminopyridine and benzaldehyde; Distillation of Benzaldeyde to ensure maximum purity from possible contaminant like water and ammonia, and refluxed with freshly prepared 2-aminopyridine. The refluxing was done with ethanoic acid catalyst at a time and without catalyst. The process was followed up with Thin Lay...

New Advancement on Nanotechnology

Smaller structures with sizes ranging from 0.1 to 100 nm are studied in nanotechnology. The pharmaceutical industry is about to undergo a great change as a result of this specialty.

Predicting the Economic Impact of Post Covid-19 in Sub-Saharan African Countries Using Gradient Boosting

The global economy has faced an unprecedented threat from the COVID-19 outbreak. The current illness is ravaging Africa at an exponential rate, and all of the continent's nations are experiencing the effects of the epidemic. In this study, we used the COVID-19 outbreak as a case study to examine the prediction of the economic impact of the pandemic in Sub-Saharan Africa (SSA). We adopted several models to work on the dataset to compare which one worked best for all 3 target variables and we d...

REMEDIATION OF SOIL POLLUTION

Remediation is the process of addressing and resolving problems or issues to make a situation better. In essence, remediation is about taking steps to rectify or improve a situation by addressing its root causes or issues. It's a proactive process that aims to make things right or better than they were before a problem or challenge arose Soil remediation is the process of cleaning, restoring, or improving the quality of soil that has been contaminated or degraded by various pollutants. This ...

The Actuarial Conditions for the Valuation of Pension Liability to Become Zero Under Minimum Funding Standard Architecture

Abstract Pension  valuation  exercises  for  a  defined  benefit  scheme  requires  an  appraisal  of  both  the  schemes  assets  and  its  liabilities  in  different  circumstances.  The  valuations  are  required  to  comply  with  regulatory standards, most notably the minimum funding standard. The objectives of this study are: (i) to compute  the  estimate  of  minimum  funding  standard  of  pension  liability  (ii)  to  establish  the  actuari...

A Mathematical Technique of Computing Technical Provisions and Premiums in General Business Insurance Under the Influence of Chain-Ladder and Cape Cod Framework

ABSTRACT An insurance company promises its policyholders to pay out benefits if certain events occur, for example, events such as a car accident and health conditions. When this is happens, the insurance company has a liability to pay the claims by technical provisions or claim reserving. The calculation of claim reserving must be done carefully in such a way that it should not cause loss to the company. Two of the common methods to calculate technical provisions in non-life insurance are the...

Impact of Information Communication Technology (ICT) on Staff Training and Development

ABSTRACT ICT (Information and Communication Technology) has greatly changed contemporary education. The ICT solutions offered enrich learning environments and provide staffs with numerous opportunities. However, even though ICT can enhance education quality, there are many staffs that are unwilling to adjust to the changes brought about by ICT. One of the most crucial inhibitory factors that make staffs reluctant to utilize ICT in education is the lack of their training on ICT. Thus, the purp...
