Application of in vitro digestion and dialysability procedure for bioavailability evaluation of toxic elements in green leafy vegetables: a realistic health risk assessment by Monte Carlo simulation

Green leafy vegetables (GLVs), which are vital and widely consumed worldwide, require monitoring for contaminants, including toxic elements (TEs). This study measured total concentrations (TC) and bioavailable concentrations (BC) of arsenic (As), cadmium (Cd), lead (Pb), chromium...

Navigating turbulence: building resilient workforce with dynamic capabilities

Purpose Drawing on the dynamic capabilities perspective, the study aims to move beyond context-dominant explanations by focusing on microfoundational mechanisms through which employees interpret and respond to dynamic work environments. In doing so, it seeks to clarify whether or...

Tailored novel nanocomposites for advanced elimination of methylene blue dye from water

Novel SrCO 3 /CuO/MgO/C (Abbreviated as CSM600) and SrCO 3 /CuO/MgO/Sr 2 CuO 2 CO 3 /Cu 2 SrO 3 /SrCuO 2 /C (Abbreviated as CSM800) multiphase nanocomposites were successfully synthesized through a Pechini sol–gel route followed by calcination at 600 and 800 °C. Structural analys...

Nonlinear 2DOF van der Pol vibrations: El-Dib’s optimized frequency formula via the two-time-domains method

This paper presents a systematic decoupling framework for strongly coupled two-degree-of-freedom (2-DOF) nonlinear vibration systems. Here, the coupling is classified as strong rather than weak because the cross-mode interaction terms in the governing equations (e.g., the x 2 y-,...

Nonlinear primary resonance and dynamic stability in parametrically excited self-sustaining curved SWCNTs subjected to a thermal and magnetic loads

Abstract This research conducts a systematic examination of the nonlinear dynamic behaviour exhibited by curved single-walled carbon nanotubes (CSWCNTs) under parametric excitation while embedded in a nonlinear viscoelastic medium. The investigation employs nonlocal Euler–Bernoul...

Theoretical Analysis of Androstenone Adsorption on Chimpanzee and Gorilla Olfactory Receptors (G‐Protein): Statistical Physics Modeling, Molecular Docking Simulation, and Thermodynamic Investigation

ABSTRACT An advanced theory based on statistical physics was applied to microscopically investigate androstenone adsorption and its relationship with olfactory perception in chimpanzees and gorillas. For this purpose, dose–response curves of androstenone on olfactory receptors of...

Physiological and transcriptional regulation of cadmium stress tolerance in ornamental pepper by silicon nanoparticles and melatonin

Nanotechnology has been established as a promising approach to improve heavy metal stress tolerance in horticultural crops. Melatonin (MT) is an emerging biostimulant for inducing stress resistance in plants. In this study, we evaluated the individual and combined effects of sili...

A machine learning framework for classifying inter-turn short-circuit faults in induction motors

Inter-turn short-circuit (ITSC) faults are among the most frequent stator winding faults in induction motors, often leading to irreversible damage. In this context, this work proposes a Machine Learning (ML) based framework for classifying ITSC faults using experimental stator cu...

Nonlinear Mixed Bi-Skew Jordan and Bi-Skew Lie Triple Higher Derivations on *-Algebras

Let A be a complex unital *-algebra containing a nontrivial projection and satisfying a Peirce-faithfulness condition. Let D={Dn}n∈N be a family of mappings from A into itself, not assumed to be additive, with D0=idA. Suppose that Dn([A•B,C]*)=∑p+q+r=n[Dp(A)•Dq(B),Dr(C)]* for all...

Effects of Proprioceptive Neuromuscular Facilitation-Based Reformer Pilates and Hatha Yoga on Functional Fitness, Balance, and Cognitive Performance in Older Women: A 16-Week Randomized Controlled Trial

Abstract Background Aging is associated with progressive declines in neuromuscular function, postural control, and cognitive performance, which may compromise functional independence. Mind–body exercise approaches such as Pilates and Yoga have been suggested as effective strategi...
