Bioremediation of Polluted Drainage with Petroleum Hydrocarbon
Abstract: This research was aimed at examining the petroleum product discharge in drainage within Port Harcourt City, samples were collected and mixed. Microbial analysis and physicochemical properties of the sample were determined. The sample was subjected into bioremediation after culturing of the microorganisms isolated, identified and characterized. The two microorganisms used are pseudomonas aeruginosa and aspergillus niger. The results obtained revealed high concentration for heavy crude oil than mixed crude oil; …

Investigation of Thermo-Acoustic Properties of Ethanol-Cyclohexane Binary Mixture
Abstract: The density, viscosity, and speed of sound for ethanol-cyclohexane binary mixtures were determined across mole fractions ranging from 0.1 to 0.9 using an Anton Paar DSA 5000 M within the temperature span of 288.15–318.15 K. From these experimental measurements, several thermodynamic and acoustic properties, such as isentropic compressibility, relative association, free volume, relaxation time, Gibbs free energy of activation, internal pressure, and solubility parameter, were derived. These parameters serve as …

Treatment of Dairy Wastewater Using Constructed Wetland
Abstract: Naturally existing wetlands have been used for dumping various types of wastewaters and have been promised to dispose of these wastewaters. As a matter of fact, in some areas, natural wetlands still serve this purpose solely and are nothing more than dumping sites. However, extensive research suggested the use of Wetlands for Treatment purposes. Understanding the dynamics of the processes in natural wetlands leads to the use of those processes …

Catalytic Applications of Carbon Nanodots
Abstract: Carbon nanodots (CNDs) owing to their hydrophilicity and multifunctionality and with ultrasmall size exhibit metal-like properties resulting in astounding catalytic performance. These nanostructures, typically less than 10 nm in diameter, possess unique physicochemical and electronic characteristics including tunable photoluminescence, high surface-to-volume ratio, abundant surface functional groups, and excellent electron transfer capabilities. Such properties have driven extensive global research into their application in heterogeneous and homogeneous catalysis. Recent advances in synthesis …

Impact of Play-Based Interventions on SeparationAnxiety in Hospitalized Under-Five Children: ASystematic Review
Abstract: Background: Hospitalization in early childhood often triggers significant fear, anxiety, stress, and distress due to parental separation, unfamiliar environments, and medical procedures, which can hinder recovery and emotional stability. Play, a natural mode of self-expression, supports children’s physical, emotional, social, and cognitive development and serves as a non-pharmacological intervention that promotes coping and relaxation. Aim: This systematic review aims to evaluate the efficacy of play-based interventions in reducing separation anxiety …
