Biomass ash (BA) represents a promising secondary resource for the restoration of degraded soils, provided that its application rate is optimized and its nutrient limitations are addressed. This study evaluated the potential of BA to improve soil properties and plant performance by first conducting controlled pot experiments and subsequently validating selected treatments under field...

Geotechnical failures in basement terrains frequently result from insufficient subsurface characterisation, leading to differential settlement and structural damage. This study applies Vertical Electrical Sounding (VES) to assess geotechnical suitability at Bolorunduro and environs, Ondo State, Southwestern Nigeria, underlain by the Precambrian Basement Complex. Twenty VES stations were...

Co-crystals are crystalline structures made up of two or more components in a definite stoichiometric ratio linked through non-covalent interactions in same crystal lattice. They differ in their biological and physiochemical properties from their components. They have wide applications in drug designing and in analysis of active pharmaceutical ingredients (APIs). The US-FDA approval for...

Chronic Hepatitis B Virus (HBV) infection remains a major global health challenge due to its persistence and progression to severe liver diseases. This study develops and analyzes a mathematical model to investigate the long-term dynamics of chronic HBV transmission. The disease-free and endemic equilibrium points, together with the basic reproduction number $\mathfrak{R}_0$, are derived and...

In recent decades, the rapid development of nanoscience and nanotechnology has significantly increased interest in the fundamental and applied properties of semiconductor nanostructures. In low-dimensional systems such as quantum wells, quantum wires, quantum dots, and other nanostructures with characteristic dimensions comparable to the electron de Broglie wavelength or the exciton Bohr...

The purpose of this article is to analyze the recent rise of China and South Korea as global leaders in the production and export of electric vehicles by examining the industrial policies these nations have implemented in the sector. This definition of electric vehicles includes all vehicles (passenger cars, buses, trucks, utility vehicles, etc.) and propulsion types that are not exclusively...

During the final stage of field exploitation, a decline in oil production is observed due to reservoir energy depletion, changes in the pressure regime, reservoir rock heterogeneity, increasing water cut, and the clogging of pore channels.Significant volumes of residual oil reserves remain in such reservoirs.Accurately assessing the current state of the reservoir-well system and forecasting...

When complaining about the Global Warming, we should look for all the factors that might have contributed to it. So far, we blame only the increased CO2 in the atmosphere for it. Nobody seems to look for other factors that might have contributed to the Global Warming: 1/ We are at the maximum of the Big Cycle of Solar Activity of 2,562.5 years – so we didn't create the Global Warming we just...

The rapid integration of artificial intelligence (AI) into education presents a critical challenge: institutions lack scalable, theoretically grounded tools to assess students' underlying cognitive and epistemic dispositions toward knowledge and technology. Understanding these dispositions is essential for personalizing learning and identifying potentially maladaptive patterns. This study...

Food waste in school catering represents a major environmental, ethical, and economic challenge. This study investigated food waste in two Tunis private primary schools operating under a centralized logistics model (reheating and service only, with three rapid shifts). It aimed to diagnose baseline waste causes and evaluate a short-term, gamified pedagogical intervention. The study targeted...

Corrosion of marine steel structures remains one of the major challenges in shipbuilding and offshore engineering, leading to significant maintenance costs, reduced operational reliability, and environmental concerns. The development of advanced protective coatings with improved durability and corrosion resistance is therefore an important research direction. Nanomodification of conventional...

The unique physicochemical properties of hybrid hydrogels create broad opportunities for their application in oil and gas engineering. In particular, these systems can be effectively utilized for formation water shut-off, selective plugging of high-permeability channels, profile control, and reservoir permeability restoration. The present study focuses on the swelling mechanisms of a...
