Hybrid nanofluids have remarkable characteristics for improving the process of heat transfer. The findings suggest hybrid nanofluids are beneficial heat transfer fluids for industrial uses. Therefore, this article aims to investigate the Darcy–Forchheimer flow of Zn-TiO_2/H2O hybrid nanofluids through a vertically porous shrinking cylinder.

The thermal transportation phenomenon of radiated hybrid nanomaterials is studied subject to linear thermal radiation and chemical species with the consequence of non-uniform heat source/sink influence. The controlling flow and energy equations in the form of governing hybrid nanofluids are developed and then converted into ODEs by operating appropriate resemblance variables. Using the impacts of controlling parameters, the behaviors of flow constraints are interpreted graphically.

The current study’s outcomes reveal that the water-based hybrid nanomaterials show a promising upsurge in heat transfer rate. Similarly, as the mass transfer rate grows, the drag coefficient and energy transfer rate boost, while due to curvature relations, it tends to diminish for drag friction. In an upper branch solution, the flow field is improved by greater porosity parameter values, whereas in a lower branch solution, it deteriorates. Furthermore, the velocity profile depicts the opposite trend for upper and lower branches due to a boost in the mixed convection parameter.

In light of already conducted studies, the relation of internal heat source varying regarding thermal and space in the rheology of hybrid TiO₂-Zn/H_2O nanofluid possesses intriguing utilization in energy production strategies due to the exhibition of extensive heat energy. The most typical examples of this phenomenon can be observed in nuclear and chemical-reactor power stations, solar power plants for heating and cooling systems, combustion analysis equipment and so on. The current study is devoted to predicting the effect of a varied heat source on the thermal energy characteristics of mixed convective hybrid TiO_2-Zn/H2O nanofluid flow through the vertical cylinder.

Induction heating as an energy source is a novel, recent method in extrusion-based metal additive manufacturing. The purpose of this paper is to develop an optimized coil for extrusion-based metal wire additive manufacturing. The optimized coil is so designed that uniform temperature distribution can be achieved in the extruder, achieving uniform material deposition in a semi-solid state, which is required for additive manufacturing.

Coil shape optimization is achieved by using arrangement of coil turns as a control variable in the form optimization process, and the objective function is to minimize the gradient in the distribution of the magnetic field to achieve uniform heating in the extruder for maintaining consistent solid and liquid fraction during material deposition. A combination of numerical solutions and geometrical optimization has been used for this study.

Experimental and simulation results reveal that the optimized induction coil produced a more uniform axial temperature distribution in the extruder, which is suitable for maintaining a uniform solid-to-liquid fraction ratio during material deposition.

The author has investigated the use of optimized-shaped induction coils in extrusion-based additive manufacturing. The optimized coil can achieve a more uniform temperature distribution in the extruder in comparison to the standard helical coil used in the existing process, which means optimized coil achieves a more uniform solid-to-liquid ratio during printing in comparison to existing standard coil shapes used for heating extruders and fulfils the requirement of additive manufacturing.

This study aims to identify factors that affect the intention and actual adoption of cashless payment (ACP) among Vietnamese youths. Extending the unified theory of acceptance and use of technology (UTAUT) model with two impelling factors (perceived trust [PTR] and lifestyle compatibility [LCM]), this study also examined the mediating effect of intention to adopt cashless payment (ICP) on the relationships of UTAUT model components with the actual ACP.

All data were collected online from 422 Vietnamese youths through online survey, and partial least squares structural equation modelling was performed to analyse the data.

The study’s results illustrated the positive and significant effects of performance expectancy, effort expectancy, facilitating conditions, LCM and PTR on ICP. However, social influence was found to exhibit a negative effect on ICP. Furthermore, ICP was found to contribute no mediation effects on the relationships of any of the components with the actual ACP.

This study’s findings are widely useful for marketers and managers to plot their promotional and campaigning strategies, emphasising factors that motivate consumers to adopt cashless payment. The obtained findings also benefit architects and designers in designing products and services by consolidating lifestyle standards and other requirements of consumers. Policymakers should implement policies and strategies to enforce rules and educate the public to widely adopt cashless payment across various sectors.

This study extended the UTAUT model with two new variables, i.e. PTR and LCM.

The purpose of this paper is to design and apply a critical framework for assessing the inclusivity of gender diversity training. The framework combines insights from intersectional feminist and postcolonial feminist theory. It is applied to assess whether and how influential gender diversity training manuals question the (re)production of systems of inequality and promote the recognition of varied lived experiences of women particularly in global workplaces.

This qualitative research was done in two stages. First, we designed a critical framework consisting of five elements taking inspiration from intersectional and postcolonial feminist theories. Second, we analysed four gender diversity training manuals from prominent international organizations to assess their inclusivity.

We found that gender diversity training manuals construct a binary understanding of gender, implying that being a woman is a universal experience. Second, the documents take a systemic approach to intersectionality, acknowledging societal systems, but the focus is on oppression as opposed to privilege, obscuring possible complexities of intersecting social categories. Third, the narratives of gender diversity trainings reflect western hegemony in referring to “global norms” and women from the global south.

The paper brings together complex theoretical strands of intersectional and postcolonial feminist theory in the form of a critical framework that can not only be used to assess gender diversity training but also be applied to other gender diversity interventions. Practical suggestions for trainers to develop more inclusive gender diversity trainings are discussed.

This research aims to uncover how the adoption process of a mobile payment solution unfolds in its local use. We examined micro-enterprises’ adoption of UPI-based payment system in India.

We employed an ethnographic approach to study the micro-entrepreneurs’ daily practice and adopted a relational ontology to conduct an “in-practice” enquiry of the UPI payment adoption process.

Applying the practice perspective of Technology Affordances and Constraints Theory, we found that UPI adoption was shaped through a dynamic interplay of emerging affordances and constraints. New features, such as All-in-one QR, enabled actions like cross-platform money transfer but also introduced challenges like fraud. Advancements in the technology addressed previous challenges but also created new hurdles. This cycle of evolving affordances and constraints within the contextual use of UPI payment technology shaped its adoption process.

The findings contribute to the existing body of mobile payment literature by elucidating the role of localized and ongoing enactment of affordances and constraints. Unlike existing adoption theories, using relational concepts of affordances and constraints revealed how the integration of mobile payment into practice leads to emergent use patterns and widespread adoption.

We emphasize the need for solutions that address localized challenges and contextual needs. The study advises policymakers to consider technology’s benefits and limitations in interventions.

The study offers a unique view on mobile payment adoption, highlighting the role of technological materiality and temporality. It reveals how the changing materiality of technology shapes the adoption process through localized affordances and constraints.

The role of small and medium enterprises (SMEs) in stimulating economic growth and innovation underscores the crucial need to understand the factors that influence their participation in public sector markets. Drawing on network theory, this research delves into the interaction effect of innovation culture and collaborative relationships on SME participation in public procurement. It assesses how collaborative relationships can serve as a vital mediator, enhancing the impact of innovation culture on SME participation in public procurement.

The research was carried out with 248 SME suppliers in Ilala district, located in the Dar es Salaam region of Tanzania, utilizing a questionnaire survey and a stratified random sampling technique. Structural equation modeling (SEM) and the Hayes PROCESS macro were employed to analyze the data.

The study findings highlight collaborative relationships as a pivotal mediator between innovation culture and SME participation in public procurement. Although no direct link between innovation culture and SME participation in public procurement was established, the results indicate a noteworthy positive influence of innovation culture on collaborative relationships, subsequently affecting SME participation in public procurement.

The research underscores the significance of promoting an innovation-driven culture to support the participation of SMEs within public procurement activities. Additionally, the research offers valuable perspectives on the role of collaborative relationships in stimulating innovation and achieving success in public procurement, guiding SME managers, policymakers and industry stakeholders in cultivating productive relationships and partnerships.

The research enhances both theoretical and practical insights, adding to the literature that addresses the effects of innovation culture and collaborative relationships on SME participation in public procurement. These insights can be valuable to policymakers and SME managers in designing appropriate strategies that foster an innovative culture and explore the benefits of collaborative relationships for effective participation in public procurement.

The natural ventilation in tall buildings is significantly different from that in low-rise buildings. It is imperative to record the wind available on site as a prerequisite for designing wind-driven natural ventilation. This paper aims to establish the significance of collecting site-based wind data and highlights the gap between the observed wind speed and the one used in practice.

The method consists of experimental study to determine the available wind speed for a 100-metre-high building in a warm and humid climate. The analytical mathematical model that uses the interpolation method based on secondary wind data was used to equate wind velocity at such heights. The study compares both methods to understand the gap in predicting the vertical wind profile.

The existing practice of using a wind rose and predictive mathematical model needs to be confirmed with site-based wind data before being used as an input parameter for designing for natural ventilation on upper floors.

Further studies can be undertaken to establish the variation of wind speed at the midriff of the building, derive an average rate of decrease in wind velocity and give a generalised wind input as a design guideline. A correction factor for the change in wind velocity can be helpful in determining the wind profile in the vertical component closest to the real-time data. The study is limited to outdoor wind velocity at various heights encountered at the windward side of the building. The study is region-specific.

The practice by designers and architects to use wind rose, composed of wind data available at 10-metre height, to design for naturally ventilated high-rise buildings is redundant. The study shows that the wind velocity profile changes beyond 20 metres. The prospect of a sustainable high-rise project is dependent on efficient natural ventilation, and hence the input wind velocity cannot be generic.

This study aimed to observe the effect of workplace spirituality (WPS) on employee silence. In addition, the study investigated the mediating role of workplace incivility on the relationship of WPS with employee silence. We further explored the WPS–workplace incivility link by testing the dark triad as the moderator.

We collected time-lagged data from 403 employees in the Indian hospitality industry. Statistical Package for Social Sciences (SPSS) and Partial Least Squares - Structural Equation Modeling (PLS-SEM) were used to observe the linkages among the study variables.

The results revealed that WPS is associated negatively with employee silence. The dark triad moderated the association between WPS and workplace incivility. Workplace incivility significantly mediated the association between WPS and employee silence.

The study findings would help organizations in promoting WPS to alleviate the occurrences of uncivil behavior at work and comprehend the negative consequences of workplace incivility such as employee silence.

To the best of the author’s knowledge, this study is the first of its kind to explore the linkage between WPS and employee silence. The paper makes a significant contribution by analyzing the interactive effect of personal (dark triad), environmental (WPS) and behavioral (workplace incivility) factors on employee silence.
