Abstract This comprehensive research examines the dynamics of magnetohydrodynamic (MHD) flow and heat transfer within a couple stress fluid. The investigation specifically focuses on the fluid’s behavior over a vertical stretching sheet embedded within a porous medium, providing valuable insights into the complex interactions between fluid mechanics, thermal transport, and magnetic fields. This study accounts for the significant impact of heat generation and thermal radiation, crucial factors for enhancing heat transfer efficiency in various industrial and technological contexts. The research employs mathematical techniques to simplify complex partial differential equations (PDEs) governing fluid flow and heat transfer.… More >

Abstract A numerical study analyzed double diffusion caused by convective and radiative heat transfer in a greenhouse with and without internal humidity sources. Two cases were examined: one considering temperature and mass concentration gradients on vertical walls and another incorporating internal humidity sources, enhancing convective and diffusive flows. Four configurations were analyzed by varying the length of the greenhouse, and the Rayleigh number was calculated over a range from 2.29 × 10¹⁰ to 6.07 × 10¹². Simulations modeled the greenhouse interior six times a day (8:00 a.m. to 7:00 p.m.), accounting for external temperature, humidity, and solar More > Graphic Abstract

Abstract Peristaltic transport of non-Newtonian nanofluids with double diffusion is essential to biological engineering, microfluidics, and manufacturing processes. The authors tackle the key problem of Sisko nanofluids under double diffusion convection with thermal radiations and electroosmotic effects. The study proposes a solution approach by using Morlet-Wavelet Neural Networks that can effectively solve this complex problem by their superior ability in the capture of nonlinear dynamics. These convergence analyses were calculated across fifty independent runs. Theil’s Inequality Coefficient and the Mean Squared Error values range from 10⁻⁷ to 10⁻⁵ and 10⁻⁷ to 10⁻¹⁰, respectively. These values showed the proposed More >

Abstract This paper studies on the theoretical ionizing radiation shielding parameter for the glass of {[(TeO₂)_0.7 (B₂O₃)_0.3]_0.7 [ZnO]_0.3}_1-x {CeO₂}_x by using two software; WinXCOM and PhyX software, which investigate the ability of cerium oxide. The investigation revealed that the 5CeZBTe glass sample, which included the greatest concentration of CeO₂ (0.05 mol), showed the greatest linear attenuation coefficient (LAC) and least values in Half Value Layer (HVL) and Mean Free Path (MFP). These results suggest that 5CeZBTe glass has significant potential as an alternative to traditional lead-based radiation shielding, offering a safer environment for both patients and healthcare professionals in More >

Abstract The need for effective shielding materials has grown as radiation-based technologies have been more widely used. Glasses doped with rare earth elements like neodymium oxide, are promising candidates due to their enhanced radiation attenuation properties. Using Phy-X software, this research examines how neodymium oxide doping affects the shielding properties of yttrium lead borotellurite glass. X-ray diffraction confirmed the amorphous structure, while density measurements showed increased density with neodymium oxide addition. The Phy-X software calculated radiation shielding parameters for gamma energies from 10^⁻³ to 10^⁵ MeV. The results demonstrate that neodymium oxide improves gamma irradiation attenuation and More >

Abstract Four Se₇₀Ge₂₀Sb₁₀ alloy samples were prepared using the melt quenching technique. To improve the energy states of the mobility gap, the samples were exposed to gamma radiation from 60Co source at various doses of 600, 1200, 1500, and 2000 Gy. The electrical characteristics were examined both before and after irradiation. The conductivity analysis revealed that all of our samples were impacted by gamma radiation. The reorganization of the amorphous lattice and the degree of radiation-induced disorder have been involved in the changes that occurred in the electrical characteristics of the irradiated samples. All irradiated and non-irradiated… More >

Abstract Wastewater generated by the textile industry contains high levels of various pollutants. Advanced conventional methods, such as chemical and electrical treatments, are effective in addressing these contaminants. However, the significant operational and capital costs associated with these conventional systems limit their accessibility for industrial stakeholders. In contrast, more economically viable methods tend to be less efficient. This study aims to identify a suitable approach for integrating photocatalytic degradation (PCD) with a low-cost method to enhance the cost-effectiveness of wastewater treatment processes in the textile sector. The study utilized silver copper sulfide (AgCuS) nanocomposites as a… More >

Abstract Climate change-driven environmental stresses, particularly ultraviolet-B (UV-B) radiation, pose severe threats to grapevine (Vitis vinifera L.) productivity and physiological stability. This study investigated the protective role of melatonin in in vitro plantlets of two grapevine cultivars, ‘Merlot’ and ‘Erciş’, subjected to low (≈8.25 μW cm⁻², 16 h) and high (≈33 μW cm⁻², 4 h) UV-B exposure. Significant cultivar-specific responses were observed (p < 0.001). The ‘Erciş’ cultivar exhibited higher oxidative stress, with malondialdehyde (MDA) levels reaching 24.30 mmol g⁻¹ FW in control plants compared with 14.91 ± 0.25 mmol g⁻¹ FW in ‘Merlot’. Melatonin provided dose-dependent mitigation, reducing MDA to… More >

Abstract Grapevine (Vitis vinifera L.) is one of the main crops worldwide, and ultraviolet-B (UV-B, 280–315 nm) radiation is emerging as a promising technical tool to enhance secondary metabolites that can contribute to the quality and health-promoting properties of both grapes and the resulting wines. However, few studies have assessed the effectiveness of UV-B supplements under field conditions. Here, we compared the effects of two different field UV-B treatments (a single supplement applied at pre-harvest, and a double supplement applied at both veraison and pre-harvest) on the phenolic composition of Tempranillo grape skins and the resulting wines.… More >

Abstract Background: Primary pulmonary lymphoepithelioma-like carcinoma (PPLELC) is a rare subtype of primary non-small cell lung cancer (NSCLC), with no established treatment guidelines. We present a case of a young female with PPLELC who achieved a pathological complete response (pCR) in both primary and metastatic lesions after receiving combined immunotherapy and radiotherapy. Case description: We present a 33-year-old female patient with stage IVa (cT2bN0M1b) PPLELC. As a first-line treatment, the patient received seven cycles of nab-paclitaxel combined with toripalimab (a PD-1 inhibitor) and achieved stable disease. This was followed by toripalimab maintenance therapy for nearly 30 months.… More >
