Study on nonlinear convective flow of hybrid nanofluids in an annulus
In this modern fluid field technology, hybrid nanofluids are of great interest to researchers due to their improved thermal properties which provide a superior improvement in heat transfer compared to nanofluids. The hybrid nanofluid flow in an annular geometry finds its relevance in engineering and material manufacturing processes such as heat exchangers, nuclear power plants, hot rolling, and heat storage systems due to their high heat transport rate. Since these devices are operated at moderate and very high temperatures adopting linear Boussinesq approximation becomes inappropriate. Owing to this, the present research is devoted to the study of flow, heat, and mass transport characteristics of hybrid nanofluid in an annulus including the effects of radial/transversal magnetic field, thermal radiation, exponential space-related heat source, uniform/non-uniform heat source and variable thermophysical properties under the nonlinear Boussinesq approximation. The fundamental equations are obtained from the laws of conservation of mass, momentum, and energy. The dimensionless governing nonlinear equations are treated analytically/numerically. Further, the sensitivity analysis using response surface methodology (RSM) is performed to enhance the understanding of heat and mass transport behavior. The significance of various flow parameters (involving in the problem) on the flow structure, thermal model, concentration field, heat, and mass transport rate are analysed through 2D/3D-surface plots and discussed quantitatively. -

Morphology of interstellar medium using multi-wavelength observations
The interstellar medium (ISM) is the matter that exists between the stars in a galactic system. The structure and composition of a galaxy can be understood by a study of the ISM. Our Galaxy is the only place where the observations of the ISM can be resolved and studied in great detail. There are various archived observations from space-based and ground-based telescopes spanning a large region of the electromagnetic spectrum. Combining these different observations with one another will help to study the ISM on a large scale. -

Key factors elevating omni-channel retail experience : A study of critical capability dimensions
Increasing digital disruption is driving the necessity for Omni-Channel Retailing, compelling the integration of online and offline channels. The line between online and physical retailing is blurring as retailers intend to deliver a unified experience anytime anywhere, than a mere channel specific experience. As customer expectation for seamless experience intensifies, and retailers organizational, operational and technical barriers persist, it would be vital to formulate a suitable strategy towards e levating Omni-Channel Retail Experience. Though prior studies have observed the need for realigning the strategy around blended advantages of multiple channels, there is a limited understanding with regards to Omni-Channel Capabilities influencing customer experience elements. Besides, it is challenging to adopt all the capabilities within a competitive timeframe. Thus, the importance of prioritizing these capabilities remains fairly underexplored. This research aims to close this gap by ascertaining key Omni-Channel Dimensions and Capabilities influencing experiential aspects, pertaining to Apparel and Fashion retail, which is a leading category in India. The research first employs a qualitative study to corroborate the appropriateness of the Omni-Channel constructs identified from literature review, in the context of Indian retail market, followed by a quantitative study to validate their influence on Omni- Channel Retail Experience. The research determines key capabilities and dimensions from a retailers perspective that underpin key experience elements. The findings established new knowledge in terms of top priority capabilities towards Omni- Channel adoption, and accordingly designed a novel framework termed Capability Priority Framework as a plausible approach to elevate Omni-Channel Retail Experience. The framework is an original contribution of this research serving as an accelerator for retailers to build and reinforce key Omni-Channel capabilities. The research provides a novel perspective of extending The Dialectic Theory of retailing to a modern context such as Omni-Channel. It serves as a basis for organized retailers in India to realign their strategy towards Omni-Channel adoption, as they embark on this path. Finally, it adds to the knowledge base on Omni-Channel, providing a conceptual background towards strategic retailing and further research in this domain. -

The effect of role of Couple stress parameter, Taylor number and Hartmann number on the onset of convection is studied. The system is most stable with respect to gravity modulation. -
A Study on the Entrepreneurial Traits and Characteristics of Waste Pickers and Their Contributions to the Economy and Ecology
Solid waste is problem created by mankind due to thoughtless consumerism and actions. But for surprise, a group of people of the same mankind is working day and night without support, acceptance or even without the consideration that they are also human being, to reduce the same problem. They are called waste pickers. The study intends to describe the aspects/qualities possessed by waste pickers to carry out waste picking and recycling for their existence. A sample of hundred waste pickers (n=100) were involved in completing the interview schedule to identify their entrepreneurship qualities and their contributions to economy and ecology, for the study a schedule which contain demographic and occupational details along with entrepreneurship audit and entrepreneurial traits Center (Vasant Desai) was used.. The ANOVA test helped to know whether there is a significant difference in the entrepreneurial trait among different variables. T-test analysis was used to compare entrepreneurial trait score and entrepreneurship characteristics score with independent sample variations. All statistical computations were carried out using SPSS. Results revealed that majority of the waste pickers are with innate qualities of entrepreneurs and they are largely contributing to economy and ecology. It also reveals facts related to demographic details like gender, education types of residents and duration in this occupation etc. They reveal that they get lot of public abuse and not at all getting any support. -
