Abstract
Purpose
The heat transport phenomenon in which energy transfers due to temperature differences is an important topic of interest for scientists in recent times. It is because of its wide range of applications in numerous domains such as electronics, heat dispersion, thermoregulation, cooling mechanism, the managing temperature in automotive mobile engines, climate engineering, magnetoresistance devices, etc. On account of such considerations, the magnetohydrodynamic (MHD) entropy rate for nanomaterial (CoFe2O4/C2H6O2) and hybrid nanomaterial (CoFe2O4+MoS4/C2H6O2) is analyzed. The Darcy–Forchheimer relation is utilized to describe the impact of a porous medium on a stretched sheet. Two nanoparticles molybdenum (MoS4) and cobalt ferrite (CoFe2O4) are combined to make hybrid nanomaterial (CoFe2O4+MoS4/C2H6O2). Heat flux corresponds to the Cattaneo–Christov model executed through heat transfer analysis. The influence of dissipation and heat absorption/generation on energy expression for nanomaterial (CoFe2O4+MoS4/C2H6O2) and hybrid nanomaterial (CoFe2O4+MoS4/C2H6O2) is described.
Design/methodology/approach
Nonlinear partial differential expressions have been exchanged into dimensionless ordinary differential expressions using relevant transformations. Newton’s built-in shooting method is employed to achieve the required results.
Findings
Concepts of fluid flow, energy transport and entropy optimization are discussed. Computational analysis of local skin friction and Nusselt number against sundry parameters for nanomaterial (CoFe2O4/C2H6O2) and hybrid nanomaterial (CoFe2O4+MoS4/C2H6O2) is engrossed. Larger magnetic field parameters decay fluid flow and entropy generation, while an opposite behavior is observed for temperature. Variation in magnetic field variables and volume fractions causes the resistive force to boost up. Intensification in entropy generation can be seen for higher porosity parameters, whereas a reverse trend follows for fluid flow. Heat and local Nusselt numbers rise with an increase in thermal relaxation time parameters.
Originality/value
No such work is yet published in the literature.

Abstract
Purpose
The presence and progression of stenosis disturb the normal circulation of blood through an artery and cause serious consequences. The proposed investigation is aimed to assess non-Newtonian characteristics of blood in an elliptical artery having stenosis. The blood is taken as Sutterby fluid flowing via a multi-stenosed elliptical cross-section artery.
Design/methodology/approach
The analytical solution of a mathematical model representing the considered problem is extracted in a non-dimensional form by utilizing the perturbation technique under the mild stenosis assumptions.
Findings
The graphical nature of these results is examined and discussed comprehensively for different physical parameters. The height and shape of stenosis are noted to have prominent effects on flow velocity. The wall shear stress and flow velocity attained high values in the stenotic portion of the artery. The non-uniform stenosis is observed to create higher resistance to the flow than the uniform stenosis. Further, a high disorder is noticed in the constricted region of the artery by streamlines analysis.
Research limitations/implications
The manuscript completely comprehends the blood’s non-Newtonian flow in the arteries of elliptical shape having multiple stenoses. The present study is about the properties of non-Newtonian blood flow through an elliptical artery with many stenoses. The Sutterby fluid model is used to describe the blood’s non-Newtonian nature. By utilizing presumptions of mild stenosis, the mathematical model’s non-linearity is decreased, and the perturbation method is applied to generate the resulting equations.
Practical implications
The presence of stenosis can significantly impact the circulation of blood flow. When an artery becomes narrowed, it can create a constriction or obstruction in the flow path of blood, which can lead to several important fluid dynamics phenomena, i.e. increased velocity, shear stress, pressure drop, etc. The presence of stenosis can cause various damages and complications in the affected blood arteries and surrounding tissues, resulting in heart attacks or diseases like atherosclerosis.
Originality/value
The work presented in the manuscript was not published earlier in any form.

Abstract
This paper provides a snapshot of educational and economic trends across South Asia with an exploratory and comparative approach. Before COVID-19, South Asia was the world’s fastest-growing regional economy, concurrently achieving major strides in poverty reduction and access to education. Despite the region’s economic and educational accomplishments, the countries of South Asia fall short of international benchmarks in public education expenditure, resulting in a persistent lag in educational quality that hampers individuals, the workforce, and overall economic productivity. The paper highlights themes in the literature, including context-specific evidence for the various theories of economic growth, the returns to education, and educational inputs (e.g., teachers and private schools) that highlight how spending can be leveraged to increase educational outcomes. In addition, it examines the relationship between education, poverty, and marginalization factors that explain why some populations are deprived of education and its benefits. We provide a broad perspective of the dynamics of the economics of education and the related challenges in this region. This discussion aims to enhance the understanding of the inefficiencies in South Asia’s educational systems and, ultimately, in the development of the region’s human capacities.

This study aims to examine the moderator effect of religiosity on the relationship between halal brand awareness and habit towards purchasing decisions of halal products.
Abstract
Purpose
This study aims to examine the moderator effect of religiosity on the relationship between halal brand awareness and habit towards purchasing decisions of halal products.
Design/methodology/approach
The quantitative method is used in this study. Descriptive and statistical (multiple and moderated regression) analyses are employed to test the hypothesis according to the research model. The data is collected using a cross-sectional design from 197 respondents consisting of business owners in North Sumatera, Indonesia.
Findings
It is found that both halal brand awareness and habit have a positive and significant effect on the purchasing decision of halal products. Meanwhile, religiosity significantly acts as a moderating variable in the relationship between awareness and purchasing decisions, as well as habit and purchasing decisions.
Research limitations/implications
This study revealed the important factor of religiosity as a moderating factor in purchase decisions of halal products. The government may need to collaborate with Islamic educational institutions to raise awareness of the halal concept and product awareness. It is assumed that individuals who know about the Islamic religion will have a higher degree of awareness of halal products compared to individuals with limited knowledge of Islam; thus, providers of Islamic education play a crucial role in raising the level of awareness of halal products. Schools may serve as catalysts for the dissemination of knowledge of halal products.
Originality/value
Developing halal product markets can be done by enhancing the religiosity level of consumers, one of them through attending formal or informal religious classes.

The primary objective of this research is to assess the influence of financial development, institutional quality and renewable energy consumption on India’s carbon emissions.
Abstract
Purpose
The primary objective of this research is to assess the influence of financial development, institutional quality and renewable energy consumption on India’s carbon emissions.
Design/methodology/approach
This study utilises econometric methodologies, specifically the autoregressive distributed lag (ARDL) model and Toda–Yamamoto causality tests, to explore the interplay among renewable and non-renewable energy consumption, financial development, economic growth, institutional quality, trade openness and carbon emissions in India spanning the years 1996–2019.
Findings
The research indicates that in India, greater utilisation of renewable energy, enhanced financial development and improved institutional quality are linked to lower carbon emissions. On the contrary, an escalation in carbon emissions is related to the consumption of non-renewable energy and greater trade openness. The Toda–Yamamoto causality tests reveal one-way causal relationships from institutional quality, financial development, non-renewable energy consumption and economic growth to CO2 emissions. Furthermore, the study identifies reciprocal causation, demonstrating that carbon dioxide emissions influence renewable energy consumption and trade openness.
Research limitations/implications
This study recommends that forthcoming research expand its focus by integrating more comprehensive indicators such as consumption, production, transport-based CO2 emissions or ecological footprint. Additionally, to bolster the rigour of future inquiries, researchers might consider exploring alternative regression analysis methods like NARDL and STAR.
Originality/value
This study addresses a significant gap in the existing literature by being the first empirical investigation into the effects of renewable energy consumption, institutional quality and financial development on carbon emissions in the Indian economy. Unlike prior research, we consider a comprehensive financial development and institutional quality index, providing a more holistic perspective. This unique approach contributes valuable insights into the environmental challenges faced by the Indian economy, offering a nuanced understanding of the complex dynamics of environmental degradation in this region.

Abstract
Purpose
The current study focuses on the relationship between total quality management (TQM) and sustainable performance (SP) and examines how TQM practices can facilitate firms' achievement of sustainable performance. Knowledge management (KM), with its four dimensions, i.e. knowledge creation (KCR), knowledge acquisition (KAC), knowledge sharing (KSH) and knowledge application (KAP), is also an essential factor for organizations. Therefore, this study also focuses on the mediating role of KM in the relationship between TQM and sustainable performance.
Design/methodology/approach
This study used a survey method to collect data from the managers of 485 manufacturing SMEs working in five major industrial cities in Pakistan. Collected data were analyzed through PLS-SEM with the help of smart-PLS.
Findings
The study's findings reveal that TQM practices positively influence the environmental and economic sustainability of the firm. At the same time, there is no evidence that TQM practices positively affect the social sustainability of the firm. Results further elaborate that TQM practices significantly affect all four dimensions of KM. Moreover, KM positively affects the two dimensions of SP, i.e. economic and social sustainability, but surprisingly, the impact of KM on environmental sustainability is not found. Finally, results indicate the significant mediating role of KM between TQM and SP.
Originality/value
This study contributes to bridging research gaps in the literature and advances how TQM, directly and indirectly, helps firms improve sustainable performance via the mediating role of KM.
