Research ArticleOpen accessEvery word in the titleSub-National Legislature and Democratic Consolidation in Nigeria's Fourth Republic: Lessons from Osun State House of AssemblyBolaji Omitola, Olusola R. OgunnubiThis paper examines the contribution of sub-national legislature in reinforcing democratic consolidation in Nigeria by drawing lessons from the Osun state legislature in South-West Nigeria. Specifically, the authors interrogate changing party composition, oversight actions and executive reactions and constituencies' activities of members of the Assembly across three terms of twelve years: 1999-2003; 2003-2007 and 2007-2011. The analysis presented in the … …Journal of Social Sciences, Vol. 12, Issue 4 · 5 Nov 2016 · 8,441 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStudies of the Terrestrial outdoor Gamma Dose Rate Levels in Ogun-Osun River Basins Development Authority Headquarters, Abeokuta, NigeriaI.C. Okeyode, A.M. OluseyeProblem statement: The natural radioactivity levels in the soils of Ogun-Osun River Basins Development Authority Headquarters, (O-ORBDA HQ) Abeokuta, South-Western part of Nigeria were measured. Approach: (O-ORBDA HQ) is a parastatal of Federal Ministry of Water Resources and Rural Development in Nigeria charged with the responsibility for the development and management of the water resources in its area of coverage. … …Physics International, Vol. 1, Issue 1 · 30 Mar 2010 · 7,923 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Integrated Approach to Modelling of Flood Hazards in the Rapidly Growing City of Osogbo, Osun State, NigeriaSuleiman Abdul-Azeez Adegboyega, Oluchi Christiana Onuoha, Komolafe Akinola Adesuji et al.In recent times, the swift and uncoordinated urban expansion in the medium sized city of Osogbo has increasingly encroached on the environmental sensitive areas. This uncoordinated exploitation of the ecological fragile areas for urban development has triggered urban flooding, which poses serious threat to human lives and properties in the city. This study therefore utilized geospatial technologies to generate flood … …Space Science International, Vol. 4, Issue 1 · 8 Jan 2018 · 13,835 accessesView PDFCite
Research ArticleOpen accessIn the author namesAnchoring Public Health Forecasts: High-Precision Obesity Prevalence Estimation Via Hybrid Geodemographic Ensemble RegressionTrenton Ward, Isaac OsunmakindeObesity remains a major driver of chronic disease and rising healthcare costs in the United States. Yet, most existing predictive models rely on single-model classifiers and rarely incorporate spatial structure or ensemble-based regression, thereby limiting their ability to capture geodemographic variation. This study introduces a hybrid unsupervised–supervised ensemble framework that integrates K-Means spatial profiling with a Stacking Regressor to address … …Journal of Computer Science, Vol. 22, Issue 7 · 31 Jul 2026 · 638 accessesView PDFCite
Research ArticleOpen accessIn the author namesAn Integrated Machine Learning Framework for Citrus Grading and Yield Prediction Using Classifier-Informed RegressionLydia Dede Obeng, Isaac O. OsunmakindeAgriculture remains a cornerstone of human sustenance, yet accurate citrus fruit grading and yield predictions remain significant challenges due to visual similarities between varieties such as oranges and grapefruits. This includes the inefficiencies of manual grading. This study presents a new dual-function machine learning system that integrates classification and regression to simultaneously grade citrus fruits and forecast crop yields. This … …Journal of Computer Science, Vol. 22, Issue 4 · 24 Apr 2026 · 1,898 accessesView PDFCite
Research ArticleOpen accessIn the author namesOligoglucans as Elicitors of an Enzymatic Antioxidant System in Zucchini Squash (Cucurbita pepo L.) Seedlings at Low TemperatureAbel Ceron-Garcia, Gustavo Adolfo Gonzalez-Aguilar, Irasema Vargas-Arispuro et al.Abstract: Problem statement: Non-controlled low temperatures affect physiological and biochemical processes leading to Reactive Oxygen Species (ROS) accumulation in plants, which normally are stabilized by the antioxidant system. Superoxide Dismutase (SOD), Ascorbate Peroxidase (APX) and Catalase (CAT) are the most important ROS-detoxification enzymes in stressed plants. Approach: The activity of these enzymes were examined in response to fungal Oligoglucans (OG) … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,308 accessesView PDFCite
Research ArticleOpen accessIn the author namesNovel Postharvest Treatment Reduces Ascorbic Acid Losses in Mango (Mangifera indica L.) Var. KentMaria A. Islas-Osuna, Norma A. Stephens-Camacho, Carmen A. Contreras-Vergara et al.Problem statement: Mango is a tropical fruit that ripens very quickly; for this reason, there has been a continuous effort to develop postharvest technologies to extend its shelf life and quality. Among them, 1-Methylcyclopropene (1-MCP) is widely used because it inhibits the action of ethylene receptors. Approach: Changes in physicochemical parameters, bioactive compounds and cell wall degrading activities were evaluated … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 9,130 accessesView PDFCite
