This paper aims to investigate the high temperature corrosion behaviour of ZrO₂-reinforced Cr₂O₃ matrix-based composite coatings on ASTM-SA213-T-22 steel at 900°C in molten salt environment. The different coatings were deposited by high velocity oxy fuel (HVOF) method.

Hot corrosion studies were conducted in simulated boiler environment in silicon carbide tube furnace at 900°C for 50 cycles on bare and HVOF-coated boiler steel specimens. Each cycle consisted 50 h of heating in the simulated boiler environment followed by 20 min of cooling in air. The weight change measurements were performed after each cycle to establish the kinetics of corrosion using thermogravimetric technique. X-ray diffraction and scanning electron microscopy techniques were used to analyse the corroded specimens.

The addition of 20 Wt.% ZrO₂ in Cr₂O₃ helped reduce corrosion rate by 89.25% as compared to that of uncoated specimen. The phase analysis revealed the presence of Cr₂O₃ and ZrO₂ phases in composite coating matrix, which may have prevented the base metal from interacting with the corrosive elements present in the highly aggressive environment and thus had increased the resistance to hot corrosion.

It should be mentioned here that high temperature corrosion behaviour of thermally sprayed ZrO₂–Cr₂O₃ composite coatings has never been studied, and to the best of the authors’ knowledge, it is not available in the literature. Hence, present investigation can provide valuable information for application of ZrO₂-reinforced coatings in high temperature fuel combustion environments.

The purpose of this paper is to examine the impact of bank financing and internal financing sources on women’s motivation for e-entrepreneurship.

Female owners of e-businesses in India were surveyed regarding their perceptions of bank financing, internal financing sources and their motivations for e-entrepreneurship.

The findings of this study show that bank financing and internal financing sources positively impact women’s motivation for e-entrepreneurship in India. The results show that family status, education, easy access to new business information and location positively impact women’s motivation for e-entrepreneurship in India. The findings also show that bank financing has a higher impact on women’s motivation for e-entrepreneurship compared with internal financing sources.

This is a co-relational study that investigated the relationship between bank financing and women’s motivation for e-entrepreneurship and the relationship between internal financing sources and women’s motivation for e-entrepreneurship. There is not necessarily a causal relationship between the two. The findings of this study may only be generalized to individuals similar to those that were included in this research.

This study contributes to the literature on the impact of bank financing and internal financing sources on women’s motivation for e-entrepreneurship. The findings may be useful for investment advisors, the Indian Government and entrepreneurship consultants.

The purpose of this paper is to examine the impact of financial support from non-resident family members (FSNRFM) on the financial performance of newer agribusiness firms in India.

Owners of newer agribusiness firms (five years old or less) from India were surveyed regarding the perceived impact of FSNRFM on the financial performance of newer agribusiness firms.

The results show that newer agribusiness firms with FSNRFM perform better than those without FSNRFM; and build higher levels of internal financing sources relative to the newer agribusiness firms without FSNRFM, which, in turn, improves their performance.

This is a co-relational study that investigated the association between FSNRFM and financial performance of newer agribusiness firms. There is not necessarily a causal relationship between the two. The findings of this study may only be generalized to firms similar to those that were included in this research.

An experimental study has been conducted to model and optimize wire electric discharge machining (WEDM) process parameters such as pulse-on time, pulse-off time, servo voltage and peak current for response characteristics during machining of Nimonic 75 alloy.

The response surface methodology (RSM)-based Box–Behnken's design has been employed for experimental investigation. RSM is used for developing quadratic regression models for selected response variables i.e. material removal efficiency and kerf width. To validate the model, confirmation experiments have been performed. The multi-response optimization has been done using desirability function approach.

Through analysis of variation, the percent contribution of process parameters on the response characteristics has been found. Pulse-off time is the most significant parameter affecting the kerf width and material removal efficiency followed by pulse-on time. The quadratic regression models have been developed for prediction of selected response variables. An attempt has been made to optimize the WEDM parameters for material removal efficiency and kerf width. The recommended process parameter setting for maximum material removal efficiency and minimum kerf width have been found to be pulse-on time = 0.6 µs, pulse-off time = 14 µs, servo voltage = 25 V and peak current = 200 A.

The “kerf width” is an important response variable for maintaining dimensional accuracy of the machined component, but has not been given due attention by the researchers. In the present work, the developed regression model for “kerf width” can be used in estimating wire offset setting and thereby getting a dimensionally accurate product. The optimum process parameters obtained in WEDM of Nimonic 75 alloy will contribute in database of machining. The outcome of this study would be added to scare database of the machining of Nimonic 75 alloy and also would be extremely useful for making the technology charts for WEDM.

This study aims to investigate the influence of process parameters of wire electrical discharge machining (WEDM) of Nimonic75. Nimonic75 is a Nickel-based alloy mostly used in the aerospace industry for its strength at high temperature.

One factor at a time (OFAT) approach has been used to perform the experiments. Pulse on time, pulse off time, peak current and servo voltage were chosen as input process parameters. Cutting speed, material removal rate and surface roughness (Ra) were selected as output performance characteristics.

Through experimental work, the effect of process parameters on the response characteristics has been found. Results identified the most important parameters to maximize the cutting speed and material removal rate and minimize Ra.

Very limited research work has been done on WEDM of Nickel-based alloy Nimonic75. Therefore, the aim of this paper to conduct preliminary experimentation for identifying the parameters, which influence the response characteristics such as material removal rate, cutting speed, Ra, etc. during WEDM of Nickel-based alloy (Nimonic75) using OFAT approach and found the machinability of Nimonic75 for further exhaustive experimentation work.

Leraning outcomes are as follows: demonstrating how companies in the Indian market are using competitive advertising; giving participants an overview of the regulatory framework for advertising in India; highlighting the complexities arising out of the multiplicity of advertising regulations and institutions in India; appreciating the legal and ethical perspectives of advertisements and self-regulation; and evaluating the stance taken by both the parties in this particular case to develop multi-stakeholder perspective.

A recent advertisement by international conglomerate Hindustan Unilever Limited was severely criticized for insulting Indian values by Baba Ramdev, promoter of India's largest Ayurvedic Company selling Indian indigenous and natural alternate medicinal products. It was in a complete reversal of the scenario between 2015 and 2018 when other Indian consumer goods companies complained against advertisements released by Patanjali. Indian fast moving consumer goods sector is witnessing a trend of competitive advertising in which companies are downplaying and criticizing the competitors. Though quite old, this trend caught momentum when Patanjali Ayurved Limited, a new player in the market, started advertising aggressively in 2015–2016. It resulted in many complaints by the aggrieved parties in the industry bodies and different courts of law in India. A part of the confusion comes from the diversity of advertising regulations across different Indian platforms and the absence of a clearly defined institutional framework for resolving such disputes. Consequently, most such disputes land up in the court of law in India. The case study builds an understanding of the legal framework within which companies are governed for brand promotions and creates a contextual ethical dilemma to drive the discourse on advertising through self-regulation in India.

This case is meant to benefit students pursuing a graduate or upper-level undergraduate degree in management or law/business law.

In February 2019, local newspapers in the Maldives published unconfirmed reports that the Indian company GMR was reinvesting in the Maldives. GMR had secured a contract in 2010 for renovation/expansion of The Maldives International Airport. However, the contract created political turmoil, with opposition parties objecting to some clauses. People considered GMR closer to the incumbent President, Mohammed Nasheed. The unstable political scenario forced President Nasheed to resign amidst allegations of corruption. The new President showed hostility toward India and GMR while making overtures to China. He canceled the airport contract and awarded it to a Chinese company. GMR went to the international Tribunal in Singapore. The tribunal upheld the Maldivian government’s right to terminate the agreement but awarded GMR a compensation of US$270m. In 2019, a new government came to power in the Maldives, with Mohammed Nasheed enjoying a commanding position. The government pledged to accept the judgment of the Singapore International Tribunal. The local media discussed the possibility of the return of GMR to the Maldives after seeing some senior GMR officials in the Maldives. However, it was not clear whether it would be a good idea for GMR.
