This study aims to analyze the effect of interrupted rolling on microstructures and mechanical properties of Mg–8Li–xGr composite is investigated.
Abstract
Purpose
This study aims to analyze the effect of interrupted rolling on microstructures and mechanical properties of Mg–8Li–xGr composite is investigated.
Design/methodology/approach
Graphene reinforced composite was developed by using stir casting route and rolled with different reduction in thickness such as 50, 75 and 90%. Microstructure, hardness and tensile characteristics of the rolled samples were evaluated.
Findings
Investigation on microstructures of rolled composite depicts that increase in rolling reduction % resulted in fine elongated grains and decreased aspect ratio. Further, it was also observed that increasing percentage of rolling reduction promotes the dissolution of ß Li phase and as a result the ductility of composite decreases. Interrupted rolled samples showcase higher hardness when compared with as-cast composite. Composite rolled with 90% reduction displays higher yield strength of 219 MPa. Hardening capacity of composites decreases with increase in reduction percentage due to the effective reduction in grain size.
Originality/value
Investigation on the influence of interrupted rolling on microstructures and mechanical properties of Mg graphene composite. The in-depth understanding of this will help to improve its wide spread application.

Abstract
Purpose
In this paper, a solid circular cylinder of finite length occupying the space 0⩽r⩽1, 0⩽z⩽h is considered. The purpose of this paper is to adopt a linear hygrothermal effect to analyze the unsteady state responses in a finite long solid cylinder subjected to axisymmetric hygrothermal loading T=TR and C=CR at the surface. The analytical solution of temperature, moisture and thermal stresses is obtained by using the integral transform technique. The coupling and uncoupling effects of temperature, moisture and thermal stresses are discussed for a graphite fiber-reinforced epoxy matrix composite material (T300/5208). The numerical results of transient response hygrothermoelastic field are presented graphically.
Design/methodology/approach
In the present problem, hygrothermoelastic response of a finite solid circular cylinder has been investigated by integral transform technique consisting of Laplace transform, Hankel transform and Fourier-cosine transform. The problem is investigated subjected to prescribed sources. Numerical algorithm has been developed for numerical computation.
Findings
The analytical solution of temperature, moisture and thermal stresses is obtained by using the integral transform technique. The coupling and uncoupling effects of temperature, moisture and thermal stresses are discussed for a graphite fiber-reinforced epoxy matrix composite material (T300/5208). The numerical results of transient response hygrothermoelastic field are presented graphically.
Research limitations/implications
The work presented here is mostly hypothetical in nature and totally mathematical.

Abstract
Purpose
The utilisation of food waste/by‐products helps to increase produce recovery and enhances nutrition in low‐cost food without any appreciable increase in product cost. The storage behaviour of the product must be studied before commercialisation of the product. This paper aims to focus on this process.
Design/methodology/approach
Extrudates (25 g) prepared under optimised conditions of proportion (rice flour, pulse powder and carrot pomace), moisture content, screw speed and die temperature, were sealed using a polythene sealing machine in LDPE bags and aluminium laminated LDPE bags. The bags were then stored for six months in an incubator at temperature of 38±2°C to evaluate the stability of the product. The extrudates were analysed for change in colour, hardness, moisture content and sensory characteristics.
Findings
Zero‐ and first‐order models were fitted for prediction purposes. The minimum overall change in color ΔE value, minimum increase in moisture content and minimum increase in hardness was observed in aluminium laminated LDPE bags. The zero order model better predicted the variation of L*, b*, ΔE, moisture content and hardness during storage, whereas first order model was better fitted for the a* value.
Originality/value
The carrot pomace has the potential to be used as a food ingredient that enhances the nutritional attributes of products along with a reduction in cost. Extruded products were successfully developed in the laboratory using carrot pomace as one of the ingredients. This study evaluates the kinetic changes during the storage of carrot pomace based extruded snacks.

Abstract
Purpose
The purpose of the present work is to improve the industry performance by identifying and quantifying the risks faced by the Indian pharmaceutical industry (IPI). The risk values for the prominent risks and overall industry are determined based on the four risk parameters, which would help determine the most contributive risks for mitigation.
Design/methodology/approach
An extensive literature survey was done to identify the risks, which were also validated by industry experts. The finalized risks were then evaluated using the fuzzy synthetic evaluation (FSE) method, which is the most suitable approach for the risk assessment with parameters having a set of different risk levels.
Findings
The three most contributive sub-risks are counterfeit drugs, demand fluctuations and loss of customers due to partners' poor service performance, while the main risks obtained are demand, financial and logistics. Also, the overall risk value indicates that the industry faces medium to high risk.
Practical implications
The study identifies the critical risks which need to be mitigated for an efficient industry. The industry is most vulnerable to the demand risk category. Therefore, the managers should minimize this risk by mitigating its sub-risks, like demand fluctuations, bullwhip effect, etc. Another critical sub-risk, the counterfeit risk, should be managed by adopting advanced technologies like blockchain, artificial intelligence, etc.
Originality/value
There is insufficient literature focusing on risk quantification. Therefore, this work addresses this gap and obtains the industry's most critical risks. It also discusses suitable mitigation strategies for better industry performance.

Abstract
Purpose
The pharmaceutical industry faces multiple risks that adversely affect its performance. Within these risks, some dependencies have been observed, which help in streamlining the mitigation efforts. Therefore, the present work identifies and categorizes various risks/sub-risks in cause–effect groups, considering uncertainty in the decision-making process.
Design/methodology/approach
An extensive literature review and experts' opinions were utilized to identify and finalize the risks faced by the pharmaceutical industry. For further analysis, data collection was done using a questionnaire focusing on finalized risks. Based on the data, the causal relation under uncertainty between various risks/sub-risks was identified using a multi-criteria decision making (MCDM) technique, i.e. intuitionistic fuzzy DEMATEL, in a pairwise manner.
Findings
The results show that the three most prominent risk categories are operational, demand/customer/market and financial. Also, out of the seven main risks, only supplier and operational are categorized within the effect group and the rest, i.e. financial, demand, logistics, political and technology within the cause group. The sub-risks within each category have also been categorized into cause–effect groups. The mitigation of cause group risks will help in economize the financial resources and improve the performance and resilience of the industry.
Originality/value
There is insufficient research on identifying the causality among the pharmaceutical industry risks. Additionally, an extensive discussion on the identified cause–effect groups is also missing in the literature. Therefore, in this work, efforts have been made to determine the prominent risks for the Indian pharmaceutical industry that will be helpful for channelizing the resources to mitigate risks for a resilient industry.

Abstract
Purpose
This paper aims to identify the dimensions of a firm’s service innovation competence. This paper also aims to establish the relationship between a firm’s service innovation competence dimensions and customer-oriented service innovation configurations and customer adoption. This study probes the supply side of service innovation to assess the key drivers or capabilities that influence the service innovation process at the firm level.
Design/methodology/approach
This study uses the triangulation method using existing theoretical concept supplemented by 18 in-depth interviews of senior level managers from service firms from three sectors – hospitality, mobile telecommunication services and financial services. The interview findings were supplemented by 12 service innovation case studies (four from each sector). Content analysis of in-depth interviews was performed using three raters, and inter-rater reliability was tested. Case studies were categorized in terms of the strength of the innovation competence dimension observed.
Findings
Based on the content analysis of the interviews and categorization of case study observations, six distinct dimensions of the firm’s service innovation competence were identified. Four attributes of each dimension were also identified. Based on the interview insights and case observations, seven propositions are suggested, and a conceptual framework is presented to establish the relationship between the firm’s service innovation competence dimensions and service innovation configurations and customer adoption.
Research limitations/implications
This study was conducted in the Indian context and remains to be tested using quantitative research. Therefore, researchers are encouraged to test the proposed framework in a different geographical context to ascertain its validity.
Practical implications
The conceptual framework presented in the paper may help managers of service firms in building innovation capabilities that are relevant to development of customer-oriented innovations. This would lead to better customer adoption of their new services.
Originality/value
This paper fills an important knowledge gap regarding the dimensions of a critical supply-side component of service innovation, that is, innovation competence. Clear identification of competence dimensions and their relationship with customer adoption extends the current knowledge on service innovation.

Abstract
Purpose
Women’s economic empowerment (WEE) has emerged as a key component at national and international policy-making agendas. The purpose of this paper is to examine and validate the antecedents of WEE for urban working women.
Design/methodology/approach
This study used a descriptive and exploratory research design. A total of 286 responses from women working in the formal sector of Delhi-NCR were collected through self-administered questionnaires on a five-point Likert scale using non-probability quota sampling technique. The sample was controlled for the employment sector, that is, healthcare, education and information technology. Exploratory factor analysis has been performed in the first step to test the data’s dimensionality with the goal of producing a set of items that reflect the meaning of the relative construct. Thereafter, confirmatory factor analysis has been used for data analysis.
Findings
Digital banking usage (DBU) has been identified as the most significant contributor to WEE.
Practical implications
Besides digital banking, government support has also emerged as a key indicator of WEE, necessitating a government policy review to improve WEE. Research findings indicate that, if WEE initiatives are to reach their full potential, they must individually address the extracted factors. This study offers a new framework for understanding and enhancing WEE for urban working women in India.
Originality/value
To the best of the authors’ knowledge, this study is the first of its kind to use factor analysis to explore the multi-dimensionality of WEE using the novel dimensions of DBU, women’s agency and government support, in addition to the established variables of financial literacy, social norms and workplace human resource policies.
