Abstract: Groundwater serves as the primary source of potable water in Maiduguri and Jere, northeastern Nigeria, where rapid population growth and limited public water supply have intensified reliance on hand-dug wells and boreholes. However, the increasing dependence on on-site sanitation systems such as pit latrines and septic tanks has raised concerns about groundwater safety. This study investigates the impact of excreta disposal practices on groundwater quality in the region, focusing on nitrate concentrations, thermotolerant coliforms (TTC), separation distances between wells and sanitation facilities, and groundwater flow patterns.......

Abstract: In its long history, our planet has undergone massive changes in climate with varying causes, and understanding the details of these events could provide a more robust framework for predicting future climate change. Earth's climate has never been static. Long before human civilization emerged, our planet experienced dramatic swings between ice ages and greenhouse periods — all recorded in the rock record. Geology offers an unparalleled......

| Title | : | Mineralogical And Geochemical Constraints On The Provenance And Weathering Of Late Quaternary Sediments From Magumeri, Nigerian Sector Of The Chad Basin |

Abstract: Late Quaternary sediments of the Chad Formation exposed around Magumeri in northeastern Nigeria were investigated to determine their mineralogical composition, provenance, weathering history, depositional environment, and economic potential. Thirteen representative sediment samples were analysed using X-ray diffraction (XRD) and X-ray fluorescence (XRF). Quartz (25.9–62%) dominates the detrital mineral assemblage, while feldspars....

| Title | : | The Himalayan Ellipse Model: Finite Element Analysis (FEA) Approach |
| Country | : | India |
| Authors | : | Amitabha Roy |
|
: | 10.9790/0990-1402012429 |
Abstract: This study employs Finite Element Analysis (FEA) to investigate the complex crustal deformation, uplift, and erosion patterns within the Himalayan syntaxial bends, specifically at Nanga Parbat (west) and Namcha Barwa (east). These "hairpin" turns, heavily influenced by the northward, counter-clockwise rotation of the Indian Plate, are simulated using continuum mechanics and viscous/viscoelastic material properties. The Himalayan arc, characterized by an elliptical shape, is modeled with a semi-major axis of 1200 km and pinned at its ends by major strike.......

Abstract: An integrated analysis of core-derived facies and well-log petrophysical data was carried out to characterize the reservoir architecture of the GABO Field in the onshore Niger Delta Basin. Detailed core descriptions were used to identify lithofacies based on grain size, lithology, and sedimentary structures. Six lithofacies were recognized, including trough cross-bedded sandstone, planar cross-bedded sandstone, ripple-laminated sandstone, horizontally......
