This study focuses on a comparative analysis of pretreated coal effluent with Hydrochloric (HCl) and Tetraoxosulphate (VI) Acids (H2SO4) activated carbon. The study is motivated by the discrepancies existing in the removal efficiency of particulate matter from effluent samples, using adsorbents that are activated by different acids of varying strengths. A sample of cow bone collected from a... Read More

Tridax procumbens leaf extract (T.procumbens) is utilized to synthesize Cupric molybdate nanostructures (CuMoO4), which are environmentally safe and can be employed as capping or reducing agents. Using UV-vis spectroscopy, XRD, SEM, and EDS, the optical, structural, and morphological properties of CuMoO4 are investigated. SEM and EDS confirmed the nanorod shape and purity of CuMoO4...

This study numerically investigated the changes in the behaviour of fluid flowing through an ejector in response to modifications in the nozzle design. The investigation involved constant mass flow of the primary stream through four nozzles (PN1-PN4) formed with a combination of straight lines and sine functions. The area of the nozzle streamwise section varied with each contour. The PN4 nozzle... Read More

This work presents a preliminary experimental performance study of a novel dual-layer emitter for all-day radiation cooling. The emitter comprises a Barium Sulphate (BaSO4) coating on a silver substrate. The cooler was tested in Abuja's tropical climate for diurnal and nocturnal operations. The reflectivity of the emitter is 0.98, which allows it to reflect light from the visible to the... Read More

In the present time, several actual problems in solid-state electronics (such as increasing the performance, reliability, and density of elements in integrated circuits such as diodes, field-effect transistors, and bipolar transistors) are being intensively solved. To increase the performance of these devices, there is an interest in the determination of materials with higher values of charge... Read More

The research was carried out at the field experiment station and cotton technical specifications laboratory during the 2021 and 2022 seasons. The cotton research institute evaluated the performance of some cotton genotypes grown in Delta, including two commercial types, Giza 94 and Giza 97, and two promising crosses ((G86 x (S106 x G89) x G94)) and S111 X ((G86 x (G77 x G81)). All samples were... Read More

Nickel oxide (NiO) nanoparticles (NPs) were successfully synthesised by using a simple and green synthetic route using the leaf extract of the plant Senna Occidentalis, which acts as a reducing and capping agent. The structural, optical, and morphological properties of NiO NPs have been analyzed through different techniques: X-ray diffractometer, scanning electron microscope (SEM), UV-visible... Read More

Evaluation of the effect of pre-harvest treatments (inorganic fertilizers and organic manure application) on the yield and storability of yam tubers was investigated. An experimental plot was chosen and cleared, ridges were prepared into which yam seedlings were planted and used for the study. A randomized complete block design (RCBD) was applied. The yam plants were nurtured till maturity and... Read More

The adsorption of dye extract from Peristophe roxburghiana (PR) onto cotton was studied to evaluate the mechanism and kinetics of the adsorption process. The study was done at temperatures (50°C, 60°C, and 70°C) and concentrations (2, 2.5, 3, 3.5, 4, 4.5, 5g/ml). Fourier-transform infrared spectroscopy was used to analyze the elemental composition of the dye and UV-VIS spectral revealed that... Read More

The paper suggests an ensemble training method that utilizes a quick adaption of the Fast Adaptive Multivariate Empirical Mode Decomposition (FA-MVEMD) and a convolutional neural network (CNN) for periocular recognition. Initially, the periocular images go through pre-processing. After pre-processing, a single-level discrete wavelet transform decomposes the image, resulting in the LL, LH, HL, and... Read More

Several antiviral drugs and their inhibitory effects against Severe Acute Respiratory Syndrome Coronavirus - 2 (SARS CoV-2) were studied by using in silico studies. Atazanavir (ATZ) and its Hyaluronic Acid conjugated drug (HA-ATZ) are potentially inhibiting the viral replication and the present study elucidates the binding efficiency of the selected drugs on the Mpro (6M03), PLpro (6W9C), and...

In this study, the thin-layer drying behavior of goat bone was investigated in a laboratory-scale oven, utilizing slice thicknesses of 10mm, 15mm, and 20mm. The drying process took place at temperatures of 120°C, 140°C, and 160°C over an 8-hour period. Ten different thin-layer drying models were applied to the collected data, with the Two-term model emerging as the most accurate in describing... Read More
