Palyno-maceral and lithological analysis was carried-out on Mamu Formation, northern Anambra Basin, Nigeria. Analyses of the palyno-maceral composition of the exposed shale unit of the Mamu Formation in the northern Anambra Basin at Ojuwo-Olijo revealed that PM-1 and PM-2 were numerous and poorly sorted, as well as medium to small-sized PM-3 and PM-4, accompanied by Structureless Organic Matter (SOM). This scenario suggests predominantly terrestrial deposition conditions, with possible variations towards coastal and lagoonal environments in certain samples.

The importance of metal nanoclusters (MNCs) and their remarkable opto-physical properties as inorganic fluorescent quantum dots for bio-imaging and applications in medical diagnosis were studied. Their significance as good replacements for oftentimes, less-effective organic analogues was demonstrated. Silver and copper nanoclusters were prepared by reducing their metal ions with sodium borohydride in aqueous solutions. Atomic force microscopy results showed that silver and copper nanoclusters with an average size of approximately 1.40 nm were synthesized from their salts.

This study investigated the environmental and health impact of gas flaring of the OML147 flow station located at Owa-Alidinma, Delta State. Air quality parameters were measured in four locations. Carbon (iv) oxide, CO2, measurements were carried out using a non-dispersive infrared (NDIR) analyzer, particulate matter PM2.5 and PM10 measurements were conducted using beta attenuation monitor (BAM) and a tapered element Oscillating microbalance (TEOM) respectively. Noise levels were assessed using a sound level meter.

Cauchy’s integral theorem for the matrix function is studied. Using the iteration formula of the Runge–Kutta fourth-order method, we advance the solution to Cauchy’s integral theorem, wherein Jacobi elliptic integrals and the Mobius transformation are applicable. It is proven that the method converges uniformly locally on the solid triangle.  The hyperbolic matrix tangent in the arc length when the contour winds once counterclockwise around the integral is computed. Numerical results have been reported with great success.

The presence of sediment deposition and erosion in the Nun River significantly impacts water quality. While sediment deposition fosters habitats for aquatic life, excessive sediment can lead to pollution and turbid water, hampering photosynthesis and endangering organisms. Conversely, insufficient sediment diminishes habitat availability for bottom-dwelling organisms. This study aims to model sediment yield and river bank erosion in the Nun River Basin.

Medicinal plants are the first natural agents used traditionally to treat a wide range of illnesses, especially infectious diseases including malaria, diarrhea, fever, anaemia and colds especially in the rural areas. In this study, the calyxes of Hibiscus sabdariffa were investigated for their mineral composition, phyto constituents and oil components. Before extraction, twenty grammes (20g) of the powdered sample was analyzed for its mineral composition using X-ray fluorescence (XRF) spectrometry. The other part was extracted by cold maceration using methanol solvent.

We study the work function of low index surface (100) of diamond (face-centered) carbon using pseudopotential plane-wave density functional calculations with the generalized gradient approximation. We consider clean, unrelaxed surfaces in the slab-supercell approximation at 0 K. Particular attention is paid to the convergence of the vacuum in the slab model with respect to slab thickness. The obtained work function, 7.53 eV, shows a slight deviation from the experimental value.

Due to lack of scalability of feature selection algorithms when applied in a centralized manner, most classification algorithms perform sub-optimally especially in the presence of irrelevant and redundant features in high dimensional datasets-large feature size small instances. Though it is imperative to remove insignificant features to improve learning, the process is complex and time-consuming.

Ivermectin is the standard medical intervention prescribed by the World Health Organization for the treatment of Human-Blackfly Onchocerciasis. This treatment is supposed to be administered twice yearly for between ten to fifteen years. This paper numerically examined the effect of unsuccessful treatment on transference dynamics of Human-Blackfly Onchocerciasis in the human society.

The purpose of this study was to assess the proximate composition, phytochemical and mineral element profile of garlic, providing insight into its possible culinary uses and health advantages. The results obtained for proximate analysis of Allium sativum (garlic) showed carbohydrates (62± 0.95%), crude fibre (1.66± 0.03%), ash (3.01 ± 0.14%), crude fat (6.05±0.78%), protein (15.37 ±1.71%) and moisture (10.62±0.69%). The results showed that Allium sativum has a high carbohydrate content and low value of moisture content indicating a longer shelf life.
