AbstractThis study investigates the synergistic effects of circular economy (CE) practices, Industry 4.0 technology, and green human resource management (HRM) practices on sustainability and performance in Indian companies. CE focuses on resource efficiency, waste minimization, and material recyclability. Industry 4.0 incorporates modern digital technologies into manufacturing, resulting in smart factories that are more efficient and flexible. Green HRM practices include implementing human resource rules that promote environmental sustainability. Using structural equation modeling (SEM) on data from 213 respondents across various Indian firms, our research reveals several novel insights, such as CE practices significantly enhancing sustainability, demonstrating their critical role in minimizing waste and improving resource management; moderating the role of Industry 4.0: Industry 4.0 technology moderates the relationship between CE practices and sustainability, and green HRM practices positively affect CE practices and sustainable performance. Moreover, the study's uniqueness stems from its comprehensive approach, which reveals that combining these three elements CE practices, Industry 4.0 technology, and green HRM creates a powerful synergy that significantly improves both sustainability efforts and overall company performance, providing actionable insights for business looking to implement more effective and integrated sustainability strategies. These findings offer a valuable roadmap for companies aiming to achieve more impactful and cohesive sustainability initiatives.

Abstract
Our previous gene expression studies in a PCB-exposed cohort of young children in Slovakia revealed that early-life exposures to PCBs and other organochlorine compounds were associated with significant alterations across several pathogenetic pathways. The present study was undertaken to further explore the high-throughput qRT-PCR-based gene expression effects by using TaqMan low-density array (TLDA) for selected genes in a sample of 55 children from the cohort. We analyzed the transcriptional changes of 11 genes in relation to PCB and organochlorine pesticide exposure levels (including DDT, DDE, HCH, and HCB), and to BMI and ethnicity in this cohort. The results indicated an overall downregulation of expression of these genes. Maximum downregulation (in fold change) was observed in the ENTPD3 gene, and the minimum level of downregulation was in CYP2D6. As per our multinomial regression model study, downregulation of LEPR gene was significantly directly correlated with all the exposure variables. Downregulation of APC, ARNT, CYP2D6, LEPR, LRP12, and MYC genes was directly correlated with BMI (kg/m2) of the individuals. Gender-specific differences in gene expression were observed in CYP2D6 (p-value 0.0001) and LEPR (p-value 0.028), while downregulation of CYP2D6 (p-value 0.01), LEPR (p-value 0.02), LRP12 (p-value 0.04), and MYC (p-value 0.02) genes was consistently observed in Roma children compared to Caucasians. The investigation of such health disparities must be emphasized in future research, together with interventions to reduce the health consequences of PCB exposures. In this context, we emphasize the importance of biomarker-based approaches to future research on genetic susceptibility to the effects of these compounds.

The present work investigates TIG in terms of strength and energy consumption during joining of dissimilar metal plates between 304 Stainless Steel and AISI 1018 Mild Steel. TIG welding basically promotes a sustainable environment because it consumes less energy. Energy conservation means to reduce imbalance between demand and energy supply that is necessary to protect ecological resources and natural environment. TIG welding is a precision welding process which makes possible for joining of thinner and lighter materials. Joining of various dissimilar metals becomes great interest owing to the different challenges that are posed by deviation in the material composition as well as the characteristics of the joined metals. The main objective is to optimize energy consumption and tensile strength by taking effective process parameters that are Current, Travel Speed and Gas Flow Rate and also determination of main influential process parameters on energy consumption and tensile strength by using Taguchi method. Contour plot has also been shown in this present investigation.

Abstract
Pectin polymers are considered for lithium-ion battery electrodes. To understand the performance of pectin as an applied buffer layer, the electrical, magnetic, and optical properties of pectin films are investigated. This work describes a methodology for creating pectin films, including both pristine pectin and Fe-doped pectin, which are optically translucent, and explores their potential for lithium-ion battery application. The transmission response is found extended in optimally Fe-doped pectin, and prominent modes for cation bonding are identified. Fe doping enhances the conductivity observed in electrochemical impedance spectroscopy, and from the magnetic response of pectin evidence for Fe3+ is identified. The Li-ion half-cell prepared with pectin as binder for anode materials such as graphite shows stable charge capacity over long cycle life, and with slightly higher specific capacity compare with the cell prepared using polyvinylidene fluoride (PVDF) as binder. A novel enhanced charging specific capacity at a high C-rate is observed in cells with pectin binder, suggesting that within a certain rate (∼5 C), pectin has higher capacity at faster charge rates. The pectin system is found as a viable base material for organic–inorganic synthesis studies.
