The present paper aims to analyse the synergistic effect of pocket orientation and piezo-viscous-polar (PVP) lubrication on the performance of multi-recessed hybrid journal bearing (MHJB) system.

To simulate the behaviour of PVP lubricant in clearance space of the MHJB system, the modified form of Reynolds equation is numerically solved by using finite element method. Galerkin’s method is used to obtain the weak form of the governing equation. The system equation is solved by Gauss–Seidal iterative method to compute the unknown values of nodal oil film pressure. Subsequently, performance characteristics of bearing system are computed.

The simulated results reveal that the location of pressurised lubricant inlets significantly affects the oil film pressure distribution and may cause a significant effect on the characteristics of bearing system. Further, the use of PVP lubricant may significantly enhances the performance of the bearing system, namely.

The present work examines the influence of pocket orientation with respect to loading direction on the characteristics of PVP fluid lubricated MHJB system and provides vital information regarding the design of journal bearing system.

This study aims to analyze the dynamic performance of aerostatic thrust bearing for different geometries of recess. Different geometries of recess of equal recess area, i.e. circular, elliptical, rectangular and annular, have been considered in analysis. The work also analyzes the influence of tilt angle on the performance of thrust bearing. To compute the unknown pressure field, the Reynolds equation governing the flow of compressible lubricant (air) has been solved using finite element formulation. Further, separate finite element formulations have been carried out to compute fluid film stiffness and damping coefficients directly. This method provides quick computation of stiffness and damping coefficients of aerostatic thrust bearing than the usual approach.

As the Reynolds equation governing the flow of compressible lubricant is nonlinear partial differential equation, the computation of the stiffness and damping coefficient follows an iterative procedure. It requires a lot of computational energy. Therefore, in the present work, a novel technique based on finite element formulation is suggested to compute air film stiffness and damping coefficient in aerostatic thrust bearing.

A novel technique based on finite element formulation is illustrated to simulate the performance of tilted pad aerostatic thrust bearing. On the basis of simulated results, following key conclusions may be drawn. The static and dynamic performance of a circular aerostatic tilted thrust pad bearing is significantly affected with a change in the value of tilt parameter and the shape of the recess.

Implications are as follows: direct computation of air film damping coefficient is performed without perturbation method in finite element method (FEM); influence of tilt on aerostatic thrust bearing is studied; influence of recess shape on aerostatic thrust bearing is observed; and finite element formulation of aerostatic thrust bearing is performed.

The present work will be quite useful for bearing designer and academicians.

Kartikey Rajput, the promoter of a food park Urban Chowk, was waiting for the Covid regulations in the country to be relaxed. The entrepreneur in him found a business opportunity to provide hygienic food with a beautiful ambience and floated a food park (Urban Chowk) with the support of his wife Nikita Agrawal in 2017 and the second edition amidst Covid in 2020. The business model was well-appreciated by food vendors as well as customers. Rajput could see future growth potential in urban India. But his aggressive business plan to open five food parks in different cities in the next three years was disrupted due to the Covid pandemic. The expansion required huge investments, and post-pandemic challenges were plenty. The decision to go beyond Ahmedabad required the selection of cities besides the major challenge of the financing choice. The new cities might have huge footfall potential but finding the right location at the right price was a different challenge. Rajput was also concerned with the sources of getting the required finances. The entrepreneur was contemplating and evaluating the alternative sources of finance available to a start-up.

This case is appropriate for a graduate and post-graduate level programme in the courses like entrepreneurial finance, entrepreneurship and strategy. This case can also be used in an executive programme on management and Management Development Programmes (MDPs) on entrepreneurship or entrepreneurial finance.

This study aims to conduct a comprehensive review and network-based analysis by exploring future research directions in the nexus of circular economy (CE) and sustainable business performance (SBP) in the context of digitalization.

A systematic literature review methodology was adopted to present the review in the field of CE and SBP in the era of digitalization. WOS and SCOPUS databases were considered in the study to identify and select the articles. The bibliometric study was carried out to analyze the significant contributions made by authors, various journal sources, countries and different universities in the field of CE and SBP in the era of digitalization. Further, network analysis is carried out to analyze the collaboration among authors from different countries.

The study revealed that digitalization could be a great help in developing sustainable circular products. Moreover, the customers' involvement is necessary for creating innovative sustainable circular products using digitalization. A move toward the product-service system was suggested to accelerate the transformation toward CE and digitalization.

The paper discusses digitalization and CE practices' adoption to enhance the SP of the firms. This work's unique contribution is the systematic literature analysis and bibliometric study to explore future research directions in the nexus of CE and SP in the context of digitalization. The present study has been one of the first efforts to examine the literature of CE and SBP integration from a digitalization perspective along with bibliometric analysis.

The purpose of this study is to analyze two global brands (i.e. Benetton and Tommy Hilfiger) and one Indian brand (i.e. Wills Lifestyle) in terms of general brand impression, brand specific associations and brand commitment. In addition, the study investigates how the regional differences in India and Indian consumers' affinity towards global brands influence the consumer-brand relationships.

The research framework has been developed based on consumer-brand relationship theory. The consumer–brand relationship is an important indicator of the success of brands, especially when brands attempt to expand to other markets (Roper and Parker, 2006; Bastos and Levy, 2012). Three brand types were chosen for this study. The choice of the US global brand is Tommy Hilfiger, the European global brand is United Colors of Benetton, and the Indian domestic brand is Wills Lifestyle. The study utilized a repeated measure (split-plot) design involving more than two independent groups. A split-plot analysis of variance analyses a design in which a repeated measure (i.e. within subjects) factor is crossed with a between-subjects (i.e. treatment variable) factor.

The results confirm the importance of global brands over local brands in the Indian apparel consumer market. This study also examined how Indian consumers' affinity for global brands influences their evaluation of the global brands and the local Indian brands.

The study expands the literature on Indian consumer brand preferences through the investigation of three brands. The theoretical background of the study is the consumer-brand relationship theory that explains the importance of consumer–brand relationship when brands attempt to expand to other markets.
