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 results of our Japanese HEASARC data reduction from Magnetic Cataclysmic Variable (mCV) FO Aqr is clearly reported in this paper. On June 5, 2009, the Suzaku team used the Suzaku satellite to observe FO Aqr for 33.4 ks with an observation ID of (404032010). Three Gaussian lines were detected via Thermal Bremsstrahlung technique which represented iron lines in our system's spectrum modeling.

Using a distributed hydrological model, this study investigated the influence of spatiotemporal ResolutionResolution of precipitation data on simulating flood peak discharge in the Ramos River Basin. Various precipitation datasets with spatial resolutions (0.25 km to 10 km) and temporal resolutions (1 hour to 48 hours) were evaluated. Results showed that finer resolutions generally provided more accurate predictions of flood peak discharge.

This study was aimed at investigating genomic variation in wild cowpea populations to understand its implications for crop improvement. The method adopted in the study encompassed population structure analysis and gene flow studies, supported by statistical tools, to elucidate genetic dynamics from 3 wild cowpea varieties grown on a complete randomized block design with 3 replicates. Results indicate distinct phenotypic traits and genomic markers associated with adaptive mechanisms, with significant variability observed across populations.

Palynological and lithofacies analysis was carried-out on dark grey shales and dark sandy clay units from Idah well-1, Northern Anambra Basin, Nigeria. Less attention has been given to hydrocarbon exploration in northern Anambra, hence this necessitated this research. The study aimed at investigating the palynological and lithofacies of study rock types in the study well sections of the basin for paleoenvironmental, paleoclimate, paleoecology and hydrocarbon potential.

The importance of institutional repositories in upholding academic integrity has been explored in this study to bridge the gap between intellectual content and ethical conduct in the pursuit of scholarly reputation by major Nigerian universities. Through a case based methodology, an i-Repo architecture abstracting institutional repository services was proposed with mechanisms that deter academic misconduct and promote a culture of originality in academic content, using the University of Benin as a case study.

The pro-delta muds of the Akata Formation, intra-Agbada source units, and Late Cretaceous Shales have all been independently argued by several authors as potential hydrocarbon sources for the known accumulations in the onshore Niger Delta Basin. The geochemical characteristics of the Akata Formation of the Niger Delta Basin are rarely discussed in published reports.

Tetracarpidium conoforum, (family-Euphorbiaceae), root bark was investigated for its Phytoconstituents and chemical characterization by high performance liquid chromatography (HPLC). The root bark was extracted by hexane and concentrated for further analysis. A portion of the crude extracts recovered by rotary evaporator was screened for their phyto constituents using standard methods and the other portion isolated by vacuum liquid chromatograpy (VLC) was characterized by infra red spectroscopy and HPLC.

Groundwater plays a crucial role in supporting human activities and ecosystems. This study conducted a thorough evaluation of the significant of groundwater potential in the study area using Geographic Information System (GIS) techniques. Various thematic maps, such as those depicting lineament density, drainage density, slope, soil, precipitation, and land use land cover, were created and integrated into the analysis. The Analytic Hierarchy Process (AHP) method was utilized to assign weights to each thematic map, achieving a consistency index of 0.61.

This paper proposes a 4-step block method for the numerical solution of first to fifth orders of ordinary differential equations (ODEs). The coefficients of the proposed scheme are obtained through interpolation and collocation techniques using a polynomial as its basis function. The derivatives were collocated at grid and off-grid points, excluding the endpoints and the method is of order 9. The stability properties of the proposed formulas are analyzed.
