Abstract

Purpose

Hot corrosion is the major degradation mechanism of failure of boiler and gas turbine components. The present work aims to investigate the hot corrosion resistance of detonation gun sprayed (D-gun) Cr2O3-75 per cent Al2O3 ceramic coating on ASTM-SA210-A1 boiler steel.

Design/methodology/approach

The coating exhibits nearly uniform, adherent and dense microstructure with porosity less than 0.8 per cent. Thermogravimetry technique is used to study the high temperature hot corrosion behavior of bare and coated boiler steel in molten salt environment (Na2SO4-60 per cent V2O5) at high temperature 900°C for 50 cycles. The corrosion products are analyzed by using X-ray diffraction, scanning electron microscopy (SEM) and field emission scanning electron microscope/energy-dispersive analysis (EDAX) to reveal their microstructural and compositional features for elucidating the corrosion mechanisms.

Findings

During investigations, it was found that the Cr2O3-75 per cent Al2O3 coating on Grade A-1 boiler steel is found to be very effective in decreasing the corrosion rate in the molten salt environment at 900°C. The coating has shown lesser weight gains along with better adhesiveness of the oxide scales with the substrate till the end of the experiment. Thus, coatings serve as an effective diffusion barrier to preclude the diffusion of oxygen from the environment into the substrate boiler steel.

Research limitations/implications

Therefore, it is concluded that the better hot corrosion resistance of the coating is due to the formation of desirable microstructural features such as very low porosity, uniform fine grains and the flat splat structures in the coating; as compared to the bare substrate under cyclic conditions.

Practical implications

This research is useful for coal-fired boilers and other power plant boilers.

Social implications

This research is useful for power generation plants.

Originality/value

There is no reported literature on hot corrosion behavior of Cr2O3-75 per cent Al2O3 coating deposited on the selected substrates by D-gun spray technique. The present work has been focused to study the influence of the Cr2O3-75 per cent Al2O3 coating developed with D-gun spraying technique on high temperature corrosion behavior of ASTM-SA210-A-1 boiler steel in an aggressive environment of Na2SO4-60 per cent V2O5 molten salt at 900°C under cyclic conditions.

Abstract

Purpose

Seeks to examine risk assessment of human settlements due to seismo‐tectonic setting of a populated area in the Himalayas, so that mitigation measures may be taken before the next earthquake takes its toll.

Design/methodology/approach

Keeping in view the seismic vulnerability of the Himalayan ranges, an earthquake scenario is considered for the Narendranagar block of Tehri Garhwal District which lies in Seismic Zone IV of the seismic zoning map of India (BIS, 1893‐2002). Damage of MSK Intensity VIII and peak accelerations of 0.25 g are expected here at any time. The hypothetical epicenter is placed near Tapowan at 30°08′10″N and 78° 20′30″E on the crest of the meandering River Ganga, where three large thrusts, viz. Garhwal, Tons Nayar and Krol, congregate. Iso‐acceleration contours plotted for the entire Narendranagar block for earthquakes of magnitude 7.0 and 7.5 are elongated along the main boundary fault.

Findings

Almost 59 percent population of the Narendranagar block was found to be vulnerable to damage associated with higher accelerations of 0.41 g.

Research limitations/implications

The topographic effects influencing the risk of settlements have not been taken into account.

Practical implications

Implications of such an earthquake on housing stock; roads; infrastructure; awareness and time of occurrence are discussed. Strategies are suggested for long‐term earthquake preparedness and short‐term action plan for emergency management.

Originality/value

The methodology evolved can be extended for other Himalayan regions.

Abstract

Purpose

Organizations are increasingly emphasizing inclusive practices to leverage the valuable potential of their human resource. This study seeks to investigate the influence of organizational norms on the experiences of inclusion among women in manufacturing organizations. This study aims to comprehend how gendered perceptions of the ideal worker shape women’s sense of inclusion within the workplace.

Design/methodology/approach

The research adopted a qualitative approach to understand women’s experience of inclusion in the manufacturing workplace. Purposive and snowball sampling techniques were used to conduct semistructured interviews with 52 professionals working in the four manufacturing organizations. These employees were working in different roles as functional managers, human resource managers, diversity officers and female employees. Interviews were analyzed following a three-step coding process. ATLAS.ti software was used to analyze the data. The study draws upon Acker’s theory of “gendered organizations” and West and Zimmerman’s concept of “doing gender” to understand workplace narratives, adapting these theories to the specific context of India.

Findings

This study highlights frequent experiences of exclusion experienced by women in the workplace. This is because of a prevalent culture that prioritizes the ideal worker image within workplace narratives, serving as a significant catalyst for these experiences of exclusion. Additionally, the study underscores how apparently supportive measures, initially appearing beneficial, can inadvertently heighten women’s vulnerability to workplace exclusion.

Originality/value

This study shows how broader national and industrial cultures, which are often male-dominated, can, further reinforce barriers to creating a gender-inclusive workplace. Overall, the study underscores the importance of addressing ideal worker narratives as pivotal steps toward fostering a workplace that is genuinely inclusive for women.

Human resource management.

Abstract

Subject area

Human resource management.

Study level/applicability

It is appropriate for graduate students majoring in human resource or business management. Students who are interested in studying Asian economies in the world, as they are the most growing economies in the world and at the same time have a shocking number of people employed in the informal sector.

Case overview

This case study talks about women workers who face a glass ceiling at the management level and deplorable working conditions at the informal level. This case involves women in the paper bag-making business, a part of the urban informal sector. The paper bag-making business provides employment and income generation for the urban poor. The focus in this study is on women production workers, rather than entrepreneurs or professional managers. Focus of the study will be on the change in the pattern of income distribution within the family-based household, the degree of bargaining power derived from productive work and income and impact of technology on the plight of unskilled women force and how technology and vocational training can lead to utilization of manpower being wasted because of lack of synergy between technology and the informal sector in India. Expected learning outcomes Four key points of selection, training, assessment and leadership all have been addressed in this case study, and the relevance of these points is important from the point of view of management students who have to understand the linkages and the hidden costs these informal sector occupations come with and then to device an appropriate strategy to bring and use these human resources to their full capacity by utilizing the existing resources instead of adding new ones, which in development economics is known as Solow residual.

Abstract

Purpose

For a state like Uttarakhand, which is located in the seismically active Himalayan region and in the vicinity of plate boundaries, estimation of seismic hazards and the preparation of a zoning map are an urgent necessity. This paper aims to focus on this hazard.

Design/methodology/approach

In total, 32 potential seismo‐tectonic source zones were identified in a very wide area in and around the state, on the basis of seismicity and tectonics, and the longer ones were segmented. The maximum magnitude that each seismo‐tectonic source zone can support was then estimated. The seismic hazard due to each seismo‐tectonic source zone was assessed at 180 sites, in terms of peak ground acceleration (PGA).

Findings

The maximum PGA at each site varied between 0.06g and 0.50g. The seismic hazard was highest around the main central thrust and the main boundary thrust, and five other thrusts between these two thrusts. This assessment was adapted to make a seismic zoning map of Uttarakhand, with five distinct zones.

Research limitations/implications

If seismo‐tectonic source zones from the contiguous regions of Nepal and Tibet were included as part of this assessment, then a higher hazard would be expected in Uttarakhand.

Practical implications

Threat perceptions of a potential earthquake disaster can be assessed in this zoning map. Disaster mitigation strategies will vary geographically, with priorities defined by the zoning map presented here. The methodology evolved has the potential to be extended to other vulnerable states in the Himalayan arc.

Originality/value

The seismic hazard assessed has been adapted to formulate a seismic zoning map of Uttarakhand.

Abstract

Questions about the role and composition of the middle class have been examined and debated in the academy and in the political sphere for more than 100 years. In analyses of the Indian middle class specifically, two questions, both addressed by Diane Davis, seem to excite the most attention. The first has to do with the definition of a middle class, a term that has its origins in a very different social formation as well as its potentially mediating function in democracy. The second and more recent question has to do with what is variously called the “new” or “emerging” middle classes – in short, the middle classes of a liberalizing India.

Abstract

Purpose

This study compared approaches to school closures in four Latin American countries (Bolivia, Colombia, Ecuador, Peru), describing the impact on the health and educational wellbeing of school-age children and youth, and evaluating their approaches in regard to continuing education through the pandemic.

Design/methodology/approach

We collected 75 publicly available documents including scientific and gray literature (government documents and news releases), that referred to school closures and their impact on children’s health and wellbeing. We did thematic analyses using open, axial, and selective coding and applied the latest Health Promoting Schools standards and indicators to the findings.

Findings

Results showed that countries followed epidemiological reasons for prioritizing school closures while adopting some policies that abide by Health Promoting School principles. While they emphasized the need to reopen schools so that instruction could continue, school closures were among the longest in the world. The most significant impacts on wellbeing identified in the four countries were related to food security and mental health.

Research limitations/implications

This study focused on a particular set of documents, and it may not capture the full spectrum of relevant information in different contexts or regions.

Practical implications

By comparing school closures approaches among four Latin American countries, this study highlights the importance of context-specific interventions. In a post-pandemic era, lessons learned from these experiences should help foster more resilient and inclusive educational systems and explore the paths forward for following the new Health Promoting Schools framework in the region.

Originality/value

Cross-country qualitative analyses on this topic are rare. This study adds to the knowledge base by eliciting lessons for future health education research and policy efforts.

Abstract

Purpose

The current corona virus pandemic had a major impact upon the health, economy and education worldwide. In India, the government as a part of the nationwide lockdown closed all educational institutions, as a consequence of which, the teaching-learning, examination and placement scenario of students were affected. UNESCO estimated that about 32 crore students have been affected in India. The adoption of an online e-learning approach tried to minimize the academic loss and stress on students. However, the online teaching transition moved on an untested and unprecedented scale in a very short span of period. The present study analyses the perception and level of acceptance of transition from offline to online learning amongst the students of higher education in Punjab.

Design/methodology/approach

The analysis was carried out by surveying 200 students of higher education from Punjab belonging to different regions. An appropriate pre-tested questionnaire was framed on Google Forms. A five-point Likert scale was employed to determine the perception of students regarding quality of audio and video lectures, instructor's content, preparation, interactiveness, discussion regarding doubts and assessing likes and dislikes of students. The data were coded-decoded in SPSS by using descriptive statistics and factor analysis.

Findings

The study revealed the level of acceptance of online study among the students of higher education in Punjab. It is found that both online and offline modes of learning process have their own pros and cons. The sudden transition from regular mode to virtual mode was not an easy task for students either. The study revealed that both online and offline study modes have been accepted by students depending upon the availability of IT infrastructure as almost half of the respondents perceived online mode and the other half offline.

Originality/value

Punjab is a recognized state of northern India. In Punjab, the quality of higher education is good and students' satisfaction is always the priority of the educational institutions. At the time of the pandemic, this sudden transition from regular to virtual mode impacted education with students coming from diverse backgrounds like urban areas, rural areas, remote areas, rural-urban areas etc. So, in the light of this sudden transition, it is important to study the viewpoint of the students of Punjab. So, the present study was conducted to understand the perception of the students toward online learning during this ongoing pandemic. For this purpose, the study employed factor analysis. Application of factor analysis in this area is unique.

Abstract

Purpose

The purpose of this paper is to discuss applied statistical design of experiment (DOE) to optimize the process of dyeing in natural fiber through the multidisciplinary photoacoustic technique.

Design/methodology/approach

First, the spectroscopy analysis of the dyestuffs was carried out based on the 23 factorial design. Second, the DOE was utilized to find which process variables were most significant in the absorption band’s intensity of the dye. Finally, the impregnation optimization of fiber was carried out based on response surface methodology.

Findings

The results showed that the dyeing process is more efficient for samples with lower level of dye concentration and dyeing procedure time. The statistical study of the effect of each preparation factor suggested that the composition of the colors has a pronounced influence in the fiber dyeing.

Originality/value

Using the DOE and photoacoustic response in the present work was clearly found and proposes a less expensive dyeing process and that reduces the harmful impact to environment.
