A detailed method used for assessing and mapping noise pollution levels in Ota metropolis, Nigeria using ArcGIS 10.5 Software is presented this paper. Noise readings were measured at a time interval of 30 min each site considered precision grade sound level meter. The map developed was based on the computed values average equivalent (LAeq) selected locations. Results study show that weighted (LAeq), background (L10) peak (L90) vary with location period day due to traffic characteristics...
Abstract The risk of natural terrestrial radioactivity on human health is often underestimated, and environmental safety awareness necessary. Hence, this study aims to assess sources gamma radiation emitter in coastal urban-environment using the radiometric technique. dosage from a parent radionuclide such as Uranium-238 ( 238 U), Thorium-232 232 Th) Potassium-40 40 K) were measured portable spectroscopy. result showed that value U activity was between 10.81 $$\pm$$ <mml:math...
Abstract This study was carried out to review different types of available innovative construction materials. It found that advancement in nanotechnology, use mineral admixture, glass and plastic, biological materials, wood other materials have contributed significantly the growth discovery production The implementation some meets requirements for sustainability, durability, reliability, safety, cost reduction, increasing quality, better mechanical physical characteristics, flexibility...
Abstract Commonly used methods for determination of antibacterial potency honey are usually the disc, agar well diffusion and dilution plate assay which had shown various demerit inaccuracies impreciseness. Therefore, suitability spectrophotometric inhibitory activity is evaluated in this study. Honeys from different sources southwest states Nigeria were assayed using 96-well micro-titre to determine minimum concentration (MIC) against enteric bacteria strains. The inhibition Nigerian honeys...
The data presented in this research show the results of experimental study acoustic behaviour coconut fibre-reinforced concrete (CFRC). CFRC was added percentages 0.25%, 0.5%, 0.75% and 1% cement. test conducted to determine amount sound that can be absorbed by fibre. showed reinforced with fibre had highest absorptive power, which treated more than other fibres, is because washing increase lignin content responsible for absorbing property. also curing time no effect on property CFRC. will...
Geoelectrical resistivity surveys have been carried out using Schlumberger configuration within the Iyana Iyesi area of Ota, Ogun state. The aim this research was to experimentally estimate hydrogeophysical parameters an aquifer (porosity, transmissivity, hydraulic conductivity and permeability) which completed successfully. Since drilling boreholes specifically compute is relatively expensive, estimation from vertical electrical soundings considered a reliable alternative. results showed...
Awareness of the dangers associated with exposure to high radiation in environment is necessary avoid its health impact, especially when staying in-door. Assessment gamma dose rate and radionuclides urban settings Ota has been carried out using a hand-held detector determine hotspot concentration study area. In this study, eighteen (18) stations were covered, radio-nuclides (Uranium-238, Thorium-232, Potassium-40) emitting from subsurface measured. The result showed that mean value for...
African locust bean (Parkia biglobosa) is a multipurpose leguminous tree species of nutritional and pharmacological value. The plant widely distributed in Africa across Nigeria's major agroecological areas (AEAs). Amidst declining cultivation production, P. biglobosa genetically threatened its natural habitats due to overexploitation, deforestation, wildfires lack improved management practices. Consequently, concerted research efforts directed towards germplasm collection assessment genetic...
Datasets contained in this article are noise level measurement carried out at 41 different locations Ota metropolis, Nigeria. The readings were measured a time interval of 30 min for each site considered using precision grade sound meter. analysis was based on the descriptors LAeq, L10, L90, LD, TNI and NEI. Results from study reflects that highest lowest equivalent levels (LAeq) recorded commercial areas (96 dB (A)) residential (52 (A)), respectively, background (L90) has values (77 (44...
Timely and reliable soil information with respect to their nature extent spatial distribution is very essential for the optimal utilization of available natural resources in sustained bases. The technology advances field remote sensing; Geographical Information System (GIS) have augmented efficiency survey. use advanced computer technologies database can be used decision making, risk assessment environmental modelling. Precisely this project aims at application high resolution satellite data...
Abstract Polymers are substances considered to have their molecular structure being built up majorly from a large amount of similar smaller units bonded together, for instance synthetic organic materials used as plastics and resins. It has been stated that due reservoir heterogeneity capillary forces affecting the water flood process causing low oil recovery after particular interim, technique implementing polymer flooding chemical mechanism introduced is rapidly gaining attention in gas...
The biodiesel production from waste soybean oil (using NaOH and KOH catalysts independently) was investigated in this study. use of optimization tools (artificial neural network, ANN, response surface methodology, RSM) for the modelling relationship between yield process parameters carried out. variables employed experimental design yields were methanol-oil mole ratio (6 - 12), catalyst concentration (0.7 1.7 wt/wt%), reaction temperature (48 62°C) time (50 90 min). Also, usefulness both RSM...
Abstract The youth plays significant role in realising the sustainable development goals (SDGs). What young people know about SDGs and how to engage with can contribute significantly realisation of within shortest possible time. Specifically, climate change is central because its substantial nexus economic, social environmental outcomes for all regions world. Thus, this study investigates awareness among secondary school students guide mitigation strategies practices attainment SDGs. adopts...
Abstract This study reports the extraction and performance evaluation of two bio-derived polymers for enhanced oil recovery applications. The displacement processes were conducted using six (6) unconsolidated sandstone core plugs. Reservoir permeability tester was used to simulate real reservoir conditions in order evaluate suitability formulated biopolymers applications at laboratory conditions. experimental results indicate effectiveness biopolymer solutions terms their superior...
Gas and oil-fired furnaces require air blower stirring mechanism to produce homogeneous metal matrix, alloyed metals metallic composites. Both the stirrer electric power that is not reliable in some urban areas non-available rural communities sub-Saharan countries. In this paper, a 20 kg tilting furnace for melting iron, gold, aluminium, lead, magnesium, copper, tin et cetera also used matrix composites through liquid metallurgy routes, designed off-grid locations.
