A parabolic trough solar collector is an advanced concentrated solar power technology that significantly captures radiant energy. Solar power will help different sectors reach their energy needs in areas where traditional fuels are in use. This study aims to examine the sensitivity analysis for optimizing the heat transfer and entropy generation in the Jeffrey magnetohydrodynamic hybrid nanofluid flow under the influence of motile gyrotactic microorganisms with solar radiation in the parabolic trough solar collectors. The influences of viscous dissipation and Ohmic heating are also considered in this investigation.

Governing partial differential equations are derived via boundary layer assumptions and nondimensionalized with the help of suitable similarity transformations. The resulting higher-order coupled ordinary differential equations are numerically investigated using the Runga-Kutta fourth-order numerical approach with the shooting technique in the computational MATLAB tool.

The numerical outcomes of influential parameters are presented graphically for velocity, temperature, entropy generation, Bejan number, drag coefficient and Nusselt number. It is observed that escalating the values of melting heat parameter and the Prandl number enhances the Nusselt number, while reverse effect is observed with an enhancement in the magnetic field parameter and bioconvection Lewis number. Increasing the magnetic field and bioconvection diffusion parameter improves the entropy and Bejan number.

Nanotechnology has captured the interest of researchers due to its engrossing performance and wide range of applications in heat transfer and solar energy storage. There are numerous advantages of hybrid nanofluids over traditional heat transfer fluids. In addition, the upswing suspension of the motile gyrotactic microorganisms improves the hybrid nanofluid stability, enhancing the performance of the solar collector. The use of solar energy reduces the industry’s dependency on fossil fuels.

The purpose of this paper is to study haemodynamic flow characteristics and entropy analysis in a bifurcated artery system subjected to stenosis, magnetohydrodynamic (MHD) flow and aneurysm conditions. The findings of this study offer significant insights into the intricate interplay encompassing electro-osmosis, MHD flow, microorganisms, Joule heating and the ternary hybrid nanofluid.

The governing equations are first non-dimensionalised, and subsequently, a coordinate transformation is used to regularise the irregular boundaries. The discretisation of the governing equations is accomplished by using the Crank–Nicolson scheme. Furthermore, the tri-diagonal matrix algorithm is applied to solve the resulting matrix arising from the discretisation.

The investigation reveals that the velocity profile experiences enhancement with an increase in the Debye–Hückel parameter, whereas the magnetic field parameter exhibits the opposite effect, reducing the velocity profile. A comparative study demonstrates the velocity distribution in Au-CuO hybrid nanofluid and Au-CuO-GO ternary hybrid nanofluid. The results indicate a notable enhancement in velocity for the ternary hybrid nanofluid compared to the hybrid nanofluids. Moreover, an increase in the Brinkmann number results in an augmentation in entropy generation.

This study investigates the flow characteristics and entropy analysis in a bifurcated artery system subjected to stenosis, MHD flow and aneurysm conditions. The governing equations are non-dimensionalised, and a coordinate transformation is applied to regularise the irregular boundaries. The Crank–Nicolson scheme is used to model blood flow in the presence of a ternary hybrid nanofluid (Au-CuO-GO/blood) within the arterial domain. The findings shed light on the complex interactions involving stenosis, MHD flow, aneurysms, Joule heating and the ternary hybrid nanofluid. The results indicate a decrease in the wall shear stress (WSS) profile with increasing stenosis size. The MHD effects are observed to influence the velocity distribution, as the velocity profile exhibits a declining nature with an increase in the Hartmann number. In addition, entropy generation increases with an enhancement in the Brinkmann number. This research contributes to understanding fluid dynamics and heat transfer mechanisms in bifurcated arteries, providing valuable insights for diagnosing and treating cardiovascular diseases.

The purpose of this study is to determine the impact of two-phase power law nanofluid on a curved arterial blood flow under the presence of ovelapped stenosis. Over the past couple of decades, the percentage of deaths associated with blood vessel diseases has risen sharply to nearly one third of all fatalities. For vascular disease to be stopped in its tracks, it is essential to understand the vascular geometry and blood flow within the artery. In recent scenarios, because of higher thermal properties and the ability to move across stenosis and tumor cells, nanoparticles are becoming a more common and effective approach in treating cardiovascular diseases and cancer cells.

The present mathematical study investigates the blood flow behavior in the overlapped stenosed curved artery with cylinder shape catheter. The induced magnetic field and entropy generation for blood flow in the presence of a heat source, magnetic field and nanoparticle (Fe₃O₄) have been analyzed numerically. Blood is considered in artery as two-phases: core and plasma region. Power-law fluid has been considered for core region fluid, whereas Newtonian fluid is considered in the plasma region. Strongly implicit Stone’s method has been considered to solve the system of nonlinear partial differential equations (PDE’s) with 10–6 tolerance error.

The influence of various parameters has been discussed graphically. This study concludes that arterial curvature increases the probability of atherosclerosis deposition, while using an external heating source flow temperature and entropy production. In addition, if the thermal treatment procedure is carried out inside a magnetic field, it will aid in controlling blood flow velocity.

The findings of this computational analysis hold great significance for clinical researchers and biologists, as they offer the ability to anticipate the occurrence of endothelial cell injury and plaque accumulation in curved arteries with specific wall shear stress patterns. Consequently, these insights may contribute to the potential alleviation of the severity of these illnesses. Furthermore, the application of nanoparticles and external heat sources in the discipline of blood circulation has potential in the medically healing of illness conditions such as stenosis, cancer cells and muscular discomfort through the usage of beneficial effects.

Circular economy (CE) practices are critical to achieving sustainable development goals. However, the recent global disruption caused by the COVID-19 pandemic has significantly impacted sustainable practices. The literature shows a significant research gap in analyzing factors that sustain CE practices in supply chains during a global disruption. This study fills the research gap by developing a mix-method approach to analyze factors for sustaining CE practices during a global disruption.

To fulfill the objectives of this study, the list of factors that sustain CE practices was first identified by conducting a literature review and finalized through an expert opinion survey. The survey finalized 18 different factors for sustaining CE practices. The finalized factors were further analyzed using the grey decision-making trial and evaluation laboratory (DEMATEL) method. The quantitative analysis confirmed the priority of the factors and their cause-and-effect relationships.

The results revealed that continued stakeholder pressure, retention of CE and sustainability culture, continued implementation of cleaner technology, feedback system and ongoing CE training for resilience issues are the top five factors that sustain CE practices during a global disruption. The study also revealed ten factors as belonging to the cause group and eight to the effect group.

This study contributes to the literature by exploring factors for sustaining CE practices during a global disruption. Moreover, the study’s findings are important in real-life situations, as decision-makers can use the findings to formulate strategies for sustaining CE practices during future global disruptions.

This paper aims to develop a scale to measure climate strategy proactivity (CSP) displayed by corporate in developing countries to attain competitive advantage (CA) and sustain it through sources of sustained competitive advantage (SOSCA). It attempts to derive sound operational definitions of CSP, CA and SOSCA through horizontal analysis of previous studies and discussions with experts and practitioners to construct a measurement scale.

Research design includes broad stages, namely, item generation, scale development and assessment of psychometric properties of the scale starting with review of literature and discussions with experts and practitioners, which were followed by a pilot and full study carried out through a cross-sectional, self-administered online survey questionnaire and assessment using suitable tools and techniques.

Findings of the study comprise development of sound operational definitions and construction of a valid and reliable measurement scale of CSP displayed by corporate to attain CA with strong psychometric properties, which is expected to be useful in developing countries not only for researchers and academics but also for the practitioners and organizations.

The information was self-reported by respondents through climate strategy proactivity questionnaire (CSPQ) and consequently can be at risk to have been influenced by bias. Nonetheless, this CSPQ scale devoid of conceptual problems can be used in developing countries in future empirical studies with the caution that its reliability and validity require further tests.

Using the CSPQ scale will help managers in developing countries in enhancing their awareness with the provision of these conceptually clear comprehensive operational definitions of CSP, CA and SOSCA with respect to the conceptual nature and the latent expressions, and draw an extensively enhanced scope of climate-conscious strategy to bring about CA.

With the data collected from a sample representing different stakeholders of Indian companies from across the country, CSPQ scale possesses significant robustness and implicative potential which can contribute to the evolution of the strategic management field by providing a valid and reliable measure of CSP in developing countries applicable under any major theoretical perspective in strategic management serving the needs of not only the empirical research but also of the management practices intended to attain CA.

The aim of this study is to understand the effects of psychological social and financial perceptions of post-retirement life and demographic characteristics on retirement planning behaviour (RPB) of the employees from different occupational sectors.

The primary data from 400 employees in central government, state government and private sector is collected through a structured questionnaire. The questionnaire comprised of 43 items to measure social and financial perceptions and RPB along with demographic information. An exploratory factor analysis (EFA) and multiple linear regression (MLR) analysis are performed to find the significant variables of social and financial perceptions influencing the RPB.

The results of exploratory factor analysis revealed three principle components of social perceptions, four of financial perceptions and three of RPB. The role clarity, involvement, obligations, uncertainty and preparations have significant impact on RPB. This study found a moderate positive correlation between RPB and extracted factors of social and financial perceptions. The study confirms the significant effect of demographic variables such as age, marital status, occupational sector, income and education levels on RPB.

The study has number of implications for government and private sector organisations involved in offering the retirement planning solutions as well as to the employees. The stakeholders may take a note of the role of psychological social (role clarity and social involvement) and financial (financial obligations, uncertainty and preparation for post-retirement life) perceptions that influence RPB. The study also provides an insight to the policy makers for considering the demographic information such as age, education, marital status and income of the employees while designing/offering the choices of retirement plans to them. Further studies are recommended to validate the findings of this study in terms of testing the effect of psychological social and financial perceptions on retirement planning behaviour of the employees.

The purpose of this paper is to analyze the influence of organizational culture (OC) on a firm’s environmental performance (EP) via the mediating variable of environmental management control systems (EMCS).

Data were collected from 314 Pakistani manufacturing firms via the questionnaire survey, and the structural equation modeling was used to test the relationships.

The stable and flexible values of OC affect the effectiveness of formal and informal EMCS. Informal EMCS mediates the relationship between flexible values and EP, whereas formal EMCS mediates the stable values and EP. Overall, the data reveal that the integration of environmental culture within an organization’s culture and control systems leads to improve EP.

The study is one of the first, to the author’s knowledge, that links OC, EMCS, and EP in a developing economy, in this case Pakistan.

ACC Limited, under Project 30-30, had targeted to produce and sell 30 million tons (mt) of cement in the year 2011. In May 2011, the Head of Central Logistics had found the target of the project to have become increasingly difficult to achieve. He believed that to sell 30 mt of cement, 30 mt had to be transported, thereby, advancing the role of the logistics function from that of a mere facilitator to a critical actor. As possible opportunities to increase sales, issues at the Bulk Cement Corporation (India) Limited (BCCI), and the plant at Wadi are being discussed in the case. The head of BCCI had raised concerns about the decreased logistical capacity of BCCI post a mandate from the Indian Railways on transporting 58-wagon rakes against 41-wagon rakes. A common belief was that with more wagons per rake, the quantity transited from Wadi would be higher. However, this was not the case and a capacity addition was being proposed. The President of Wadi Cluster had expressed that as an effort to reduce the transit time between Wadi and BCCI, priority was given to loading for BCCI. Though an improvement was observed with the introduction of 58 wagons per rake, Wadi was facing issues. This had affected Wadi's ability to serve other markets. The focus of the case is on analysing the options being considered by ACC to increase market presence, logistics capacity at BCCI, and the overall throughput at Wadi.
