Cross-platform mobile application development using the low code technology and free and open-source technology
Get PDFCross-platform mobile application development has become a crucial tactic for organizations to reach a wider audience in today’s fast-paced digital ecosystems. To maximize user engagement developers must create applications that work flawlessly across several platforms, such as ios and android. The use of low-code and free and open-source technologies in crossplatform mobile application development is explored in this research. This project makes use of the alpha anywhere community edition software as the low code tool which offers x-basic coding system, pre-built components, and easy visual interfaces while the mysql serves as the free and open-source database which is strong in security, reliability and can help contain scalable applications at minimal cost. The project development took advantage of the benefits of both methods by integrating the low code platform and free and open-source technology. rapid application assembly was made possible by the low-code platform, while free and open-source framework offers the performance and flexibility needed for cross-platform development. In conclusion, cross-platform mobile application development using low code and free and open-source technologies is an appealing option for organizations looking for effective, affordable, and scalable solutions.
A comparative machine learning framework for breast cancer diagnosis: Benchmarking algorithms and emphasizing model interpretability
Get PDF This study evaluated the performance of four machine learning models regularized logistic regression (GLMNET), random forest (RF), extreme gradient boosting (XGB), and support vector machine (SVM) for the binary classification of breast cancer cases using a dataset comprising 357 benign (62.7%) and 212 malignant (37.3%) samples. Model training and evaluation were performed using repeated cross-validation, with performance assessed through ROC, sensitivity, specificity, and accuracy. Among the models, GLMNET achieved the best performance, with the highest cross-validation ROC (0.992) and a strong balance between sensitivity (0.982) and specificity (0.935). On the independent test set, GLMNET demonstrated excellent discrimination (AUC = 0.998), high accuracy (98.2%, 95% CI: 93.8–99.8), sensitivity (98.6%), and specificity (97.6%), with a Kappa of 0.962 indicating near-perfect agreement. Feature importance analysis revealed PC02, PC01, and PC04 as the most influential predictors. These results suggest that GLMNET provides robust and highly accurate classification performance, making it a suitable model for breast cancer prediction in this dataset.
Manifestations du Contact des Langues et de Diglossie dans Allah n’est pas Oblige et Quand on Refuse on Dit Non D’ahmadou Kourouma
Get PDFLa situation linguistique en Côte d\u27Ivoire est de nature multiculturelle et multilingue. Il s\u27agit d\u27une combinaison de langues nationales et étrangères, dont le malinké et le français sont les plus parlées. Cette cohabitation conduit au contact des langues qui est un phénomène social et linguistique par lequel des locuteurs de langues différentes vivent, opèrent et communiquent entre eux dans une communauté donnée. Cette communication analyse la situation linguistique tout en montrant les manifestations du contact des langues et l’état de diglossie dans deux oeuvres d’Ahmadou Kourouma : Allah n’est pas obligé désormais (ANO) et Quand on refuse on dit non désormais (QRN). L\u27objectif de cette étude est de montrer au public africain et surtout aux Européens les valeurs linguistiques et socioculturelles des langues qui par rapport à l’Ocident sont dites mineures et inférieures. Pour atteindre cet objectif, nous nous sommes inspirés de la théorie de diglossie de Ferguson 1959. Cette théorie met en évidence les situations linguistiques dans lesquelles deux langues voire plusieurs langues sont présentes. Cette théorie nous a permis de découvrir que le français cohabite pacifiquement avec le malinké à travers des interférences linguistiques, des emprunts, des alternances codiques, l’emploi des proverbes et de la traduction littérale. Enfin, Cette communication met en évidence l’importance du système de communication et les valeurs lexicographies en Afrique avant l’arrivée des Blancs 
Assessing the impact of Sternochetus mangiferae (Coleoptera: Curculionidae) infestation on morphometrics and nutritional composition of mango
Get PDF Sternochetus mangiferae (mango seed weevil) is a major pest affecting mango production, leading to significant economic and nutritional losses. This study evaluated the impact of S. mangiferae infestation on the morphometric, nutritional, and anti-nutritional properties of three mango varieties (Oyo, Ogbomoso, and Palaba) collected from different locations in Ibadan, Nigeria. Infested and non-infested mango fruits were analyzed for their physical attributes, nutritional composition, and anti-nutritional factors. Results showed significant reductions (p < 0.05) in fruit weight, seed length, and seed width in infested samples across all varieties. Adult infestation led to decreased crude protein, ash, and ether extract contents, with notable declines in calcium, magnesium, and iron levels. Anti-nutritional factors such as saponin, tannin, and flavonoid also showed reductions in infested samples. The percentage of infestation varied across locations, with the highest infestation rate recorded at Omi Adio (50%) and the lowest at Ojoo (26.67%). Among mango varieties, Palaba exhibited the highest infestation (48.33%), while Oyo had the least infestation (30%). These findings highlighted the detrimental effects of S. mangiferae infestation on mango fruit quality, emphasizing the need for effective pest management strategies to mitigate post-harvest losses and preserve nutritional integrity
Comparative effects of poultry manure and NPK top dress with urea on growth and yield of maize
Get PDFABSTRACT
The study aimed at determining the effects of poultry manure and NPK top dress with urea on the growth and yield of maize. The experiment was conducted using soil collected from a home soil and the Teaching and Research Farm of Kwara State University. The treatments included a Control, NPK, NPK 15-15 -15 RD (100% top dressed N with prilled urea), NPK 15-15 -15 RD (100% top dressed N with granular urea), NPK 15-15 -15 RD (100% top dressed N with neem- coated urea) and Poultry manure 10 t/ha. Treatments were laid out in a completely randomized design with three replications. Results show that application of different fertilizers improved soil chemical properties and maize growth and yield in both experimental soils; however, urea fertilizer top- dressed with NPK showed better maize growth than poultry manure. The study demonstrates that application of NPK top-dressed with granular urea and neem-coated urea significantly improved maize growth and kernel weight. This is attributed to the steady release of nutrients, particularly nitrogen, which supports cell division and growth. The effect of NPK top-dressed with nitrogen sources on soil fertility was positive, as it increased soil N, exchangeable K, organic carbon, and clay content after harvest.

Review of the use of clay-based composites for water filtration application in rural areas
Get PDFA safe water source is one that is available, accessible, and provides water of acceptable quality, free from microbial and chemical contaminations. However, millions living in rural areas have no access to safe water. About 60 percent of Nigerians live in rural areas and have a larger share of inadequate supply of safe drinking water. Consumption of contaminated water leads to highly contagious disease infections and can lead to loss of lives or reduction in life expectancy. Clay-based Composite Water Filter (CCWF) treats water and makes it safe for consumption. They are made from a mixture of clay and carbonaceous material. The principle underlying this water treatment method is that the carbonaceous material is burned off during firing, leaving pores that are large enough to allow water to pass through but small enough to trap bacteria and other water contaminants, such as dissolved solids, and in some cases virus. This review summarizes published works on the parameters (filter materials, firing temperature, shape of the filter, etc.) that influence the performance of CCWF and the corresponding results of these parameters. This is to enable producers of CCWF make informed decisions.
RIGHT TO EDUCATION OF THE GIRL CHILD AND PRACTICE OF CHILD MARRIAGE IN NORTHERN NIGERIA: CHALLENGES AND WAY FORWARD
Get PDFChild marriage is a perennial problem that is common and peculiar in Northern Nigeria with attendant increase in number of out of school girls. Efforts are made to contain the trend of child marriage as can be gleaned from the enactment of Child’s Right Act which prohibits child marriage. However, Child Right Laws in most states of the North seem to permit child marriage where the child has attained puberty. Out of several options that are been considered as possible solutions to the problem of child marriage, the strategy that seems to have agitated the international community, government and other stakeholders is free and compulsory education of the girl child. This paper adopted doctrinal method of research to examine the practice of Child marriage and how compulsory education impacts practice of child marriage in the North. Thus, the research question was, what is the best way forward for addressing the prevailing culture of marriage with children in Northern Nigeria? This paper has found that some legislation and customs seem to permit child marriage and betrothal despite the acclaimed right of the girl child to free, and compulsory education, and the International legal instruments which do not permit child marriage. More so, the problem of marriage with a child requires a multi- faceted approach rather than the compulsory education approach which seems restrictive. Thus, it has been recommended that the Child Right Laws of the Northern states should be amended to clearly prohibit child marriage in the North, and proscribe customary practices that promote marriage with a child.
SUSTAINABILITY OF SUKUK (ISLAMIC BOND) AS FINANCING INSTRUMENT FOR BRIDGING INFRASTRUCTURAL DEFICITS IN NIGERIA
Get PDFSukuk has become a viable financial instrument to reduce infrastructural deficit or the number of abandoned projects in the global capital market across the whole world. Recent situations reveal that the financial instability and inadequacy of funding at the disposal of the government to provide good facilities and maintain them are the major factors that heavily contributes to the infrastructural deficits in Nigeria. This calls for the pressing need to handle the situations. Adopting a doctrinal method, the paper reviewed and extensively analyzed the existing works on sukuk as being currently practised in Nigeria. The paper addressed the sustainability of sukuk as one of the alternative sources of funding in bridging the infrastructural deficit in Nigeria. The paper examined the challenges in the practice adoption sukuk in Nigeria. The paper recommends, among others, that if sukuk regime gains wider acceptance in Nigeria by tackling all the highlighted challenges, it will enhance the infrastructural development in the country.
THE DOCTRINE OF ADVERSE POSSESSION IN MODERN PROPERTY LAW: A REASSESSMENT
Get PDFAdverse possession is a legal doctrine that permits a trespasser to acquire title to land by continually occupying it for a prolonged period, usually twelve years, without the authorisation of the land owner. This doctrine occurs when a stranger takes over land he does not own. This situation of possession can happen intentionally or unintentionally, with a squatter or trespasser occupying the land, such as when someone unknowingly encroaches on the land of his neighbour. This doctrine has become rooted in the property law of many jurisdictions. Still, modern intricacies are challenging this age-long rule in a bid to balance the competing interests of adverse possessors and true owners. Against this background, this paper examines the theoretical underpinnings of adverse possession, the evolution of the doctrine through case law and statutory limitations, and the modern challenges and criticism of adverse possession. It renders policy reforms as recommendations for the modification of the doctrine or total expulsion from the realm of modern property law. The paper accentuates the contemporary realities of absentee landlords or land owners and as part of its findings, contends that the social policy considerations of adverse possession are contrary to fairness and justice and tantamount to enabling land grabbing. The article recommends the remedy of compensation for the landowner or abolition of title to land through adverse possession as done in Singapore.
