Dynamical analysis of a 3-species food chain model considering the impact of refuge and harvesting factors
This paper proposes a nonlinear mathematical model that describes the dynamics of a 3-species food chain consisting of a prey, an intermediate predator, and a top predator, while explicitly incorporating the effects of refuge and harvesting. Initially, the model’s fundamental qualitative…

Statistical and machine learning analysis of diesel-butanol fuel blending effect on CI engine’s exergy and environmental performance parameters
This study investigates the performance, exergy behaviour, and environmental impact of diesel–butanol blends in a Tempest four-stroke, water-cooled, direct-injection CI engine operating over a wide speed range (1200–3600 rpm). Engine simulations were performed for butanol concentrations from 0 to…

Magnetic Fe3O4-modified mangrove biochar for adsorptive removal of 2,4,6-trichlorophenol
2,4,6-Trichlorophenol (TCP) is a persistent organic pollutant with low biodegradability. Mangrove leaf biomass was pyrolyzed at 650 °C and functionalized with Fe₃O₄ nanoparticles through in situ co-precipitation to produce a magnetic biochar composite. XRD, FTIR, SEM–EDX, and BET analyses confirmed…

Novel analytical solutions to the (3 + 1)-dimensional Hirota–Satsuma–Ito-Like equation by using the generalized exponential rational function technique
In the present study, we investigate the (3 + 1)-dimensional Hirota–Satsuma–Ito-Like (HSIL) equation to derive some novel analytical solutions. The HSIL equation arises in various physical phenomena, including fluid dynamics, non-linear optics, and plasma physics. We obtain novel analytical…

Investigating the impact of soiling on the performance of various solar cell technologies
One of the main factors challenging the deployment of solar energy technologies in desert-like climates is dust. Most previous studies of soiling have focused on how total PV power output declines with time as dust accumulates. This study takes a different approach by examining how dust affects…

A thermodynamic analysis on the sodium alginate based zirconium oxide nanofluid flow between a moving and a porous disk
The current work focuses on the computational analysis of heat transfer behaviour in sodium alginate-based zirconium oxide nanofluid flowing through a channel formed by parallel squeezing disks under the influence of an external magnetic field. Due to its broad engineering applications, notably in…

On lower bounds for the energy of graphs
The concept of the energy of a graph was introduced by Gutman in 1978, inspired by the Hückel molecular orbital theory, which approximates the total [Formula: see text]-electron energy of a conjugated hydrocarbon molecule using the energy of its molecular graph. Let G be a graph on n vertices with…

A novel hybrid numerical method for delay differential equations with delay-dependent nonlocal condition
This paper develops a novel hybrid numerical method for the [Formula: see text]-uniform approximation of singularly perturbed second-order delay differential equations subject to delay-dependent nonlocal boundary condition. The proposed scheme is constructed by integrating an exponential fitting…

Dynamics and parameter estimation of a monkeypox model via non-standard finite difference
In this paper, we propose a discrete-time monkeypox epidemic model with a saturated incidence rate using a non-standard finite difference (NSFD) scheme. The model consists of four human population compartments and three animal population compartments. We have investigated that the model has…

Computational study of thermal radiation and magnetic field effects on Casson fluid flow using Hermite wavelets
This study presents a numerical investigation of steady two-dimensional magnetohydrodynamic (MHD) boundary-layer flow and radiative heat transfer of an incompressible Casson fluid over an exponentially stretching sheet with velocity slip, thermal slip, and wall suction/blowing. Thermal radiation is…

Evaluation of unmodified commercial gold screen-printed electrodes for cyclic-voltammetric detection of patulin: analytical response and limitations
Patulin (PAT) is a mycotoxin of regulatory concern in apple-based foods. We evaluated label-free gold screen-printed electrodes (Au/SPEs) against carbon and platinum SPEs for PAT electro-reduction in Britton–Robinson buffer. Au/SPE produced a reproducible cathodic response and was selected for…

Artificial intelligence modelling of cobalt chromite (CoCr2O4) nanofluid flow over a curved surface with melting phenomena and nonlinear thermal radiation
This research looks at the incompressible flow of a cobalt chromite nanoparticle mixed with water and ethylene glycol in a 50:50 ratio, passing through a Darcy–Forchheimer porous medium with a curved stretching surface embedded in it. Included in the model are four typically handled separately…

Thermal performance and flow characteristics of methanol based Fe3O4-CoFe2O4-Co3O4 nanofluid systems: numerical and ANN approaches
The study examines the thermal transport and fluid flow characteristics of Fe3O4, CoFe2O4 and Co3O4 nanoparticles suspended in methanol within convergent-divergent channels. This paper investigates two different flow regions: Region I, which considers the presence of radiation and heat…

Total edge-betweenness centrality measure of a graph
Edge-betweenness centrality measure is an important centrality measure that focuses on the role of edges in a graph. The total edge-betweenness centrality measure (EBCM) of a graph is defined as the sum of the edge-betweenness centrality measures of all its edges. In this work, we derive an…

Pterospermum acerifolium leaves, PAL a low-cost bio-based adsorbent for the efficient agricultural waste biomass for removal of noxious bromophenol blue
The sustainable management of dye-contaminated water requires treatment materials that are not only effective but also low-cost, reusable, locally available, and environmental friendly. In this study, agricultural waste biomass derived from Pterospermum acerifolium leaves (PAL) was converted into a…

New fixed point theorems for fuzzy mappings via R-contraction
In this manuscript, we introduce the concept of fuzzy R-contraction and establish the existence of fixed points for fuzzy mappings satisfying the fuzzy R-contraction condition. The results of this study will help researchers develop new methods for investigating fixed point theorems for fuzzy…

Integrated methane emission modelling and waste-to-energy scenario analysis for a circular low-carbon waste sector in Bahrain: a comparison of IPCC and LandGEM approaches and policy implications
Rapid growth in municipal solid waste (MSW) generation, limited land availability, and exclusive dependence on the Askar landfill have placed Bahrain’s waste sector under increasing environmental and climate pressure. This study develops an integrated assessment of MSW quantities, landfill methane…

Transformation and utilization of mushroom baglog waste into sustainable energy: a circular method via charcoal briquette fabrication
The trash from oyster mushroom baglog generated during growing has environmental issues if inadequately managed, since it can elevate organic waste levels and its decomposition generates hazardous methane gas. This project sought to apply circular economy concepts by transforming mushroom baglog…
