Three-dimensional printing (3DP) is an established process to print structural parts of metals, ceramic and polymers. Further, multi-material 3DP has the potentials to be a milestone in rapid manufacturing (RM), customized design and structural applications. Being compatible as functionally graded materials in a single structural form, multi-material-based 3D printed parts can be applied in structural applications to get the benefit of modified properties.

The fused deposition modelling (FDM) is one of the established low cost 3DP techniques which can be used for printing functional/ non-functional prototypes in civil engineering applications.

The present study is focused on multi-material printing of primary recycled acrylonitrile butadiene styrene (ABS), polylactic acid (PLA) and high impact polystyrene (HIPS) in composite form. Thermal (glass transition temperature and heat capacity) and mechanical properties (break load, break strength, break elongation, percentage elongation at break and Young’s modulus) have been analysed to observe the behaviour of multi-material composites prepared by 3DP. This study also highlights the process parameters optimization of FDM supported with photomicrographs.

The present study is focused on multi-material printing of primary recycled ABS, PLA and HIPS in composite form.

This paper aims to encapsulate the gendered support and hindering factors along with the role of the state experienced by Delhi-based women entrepreneurs in setting up/operating their enterprises amidst the challenges posed by the coronavirus disease 2019 (COVID-19) pandemic.

The study used mixed methods to explore the challenges faced and recovery mechanisms adopted by women entrepreneurs with special reference to the COVID-19 pandemic. A total of 50 Delhi-based young women entrepreneurs (42 actual entrepreneurs + 8 prospective/struggling entrepreneurs) selected using snowball/purposive sampling were studied through both a semi-structured questionnaire and personal interviews. National Small Industries Corporation (NSIC) and micro, small and medium enterprises (MSME) were consulted for the government’s policy documents and data. The SPSS package was used for quantitative data analysis.

Low-budget/very small-scale women entrepreneurs face common as well as gender-based challenges in the context of the market, finance, social capital, family support and awareness in addition to accessing the state’s resources/policies in both their startups and crisis situations, such as the COVID-19 pandemic. Although gender sensitization, entrepreneurial family background, and equal access to technology and the Internet has enabled women entrepreneurs to initiate, adapt, and scale their enterprises, male domination within the family, society, market, and state apparatuses is omnipresent and has served as a bottleneck for women-owned startups while hindering the recovery of their enterprises amidst the COVID-19 pandemic.

The study was limited to exploring the challenges and prospects of Delhi-based women entrepreneurs at the beginning of their enterprises and amidst the COVID-19 pandemic. On the other hand, the study had access to data and facts announced by the Indian government. No data were available on the implementation of policies and programs, and therefore specific policy analysis was not attempted. However, the reachability and accessibility of government resources and policies were employed.

The study highlights the complexity of patriarchy, which hampers women entrepreneurs in all family, society, market and state domains. Therefore, policy enactment and implementation and further research on women entrepreneurship are suggested to focus more deeply on the gender dimension.

The data used in this work comprised inputs from government sources as well as insights from fieldwork that have not been used by any other publication.

The study aims to map the links between Industry 4.0 (I-4.0) technologies and circular economy (CE) for sustainable operations and their role to achieving the selected number of sustainable development goals (SDGs).

The study adopts a systematic literature review method to identify 76 primary studies that were published between January 2010 and December 2020. The authors synthesized the existing literature using Scopus database to investigate I-4.0 technologies and CE to select SDGs.

The findings of the study bridge the gap in the literature at the intersection between I-4.0 and sustainable operations in line with the regenerate, share, optimize, loop, virtualize and exchange (ReSOLVE) framework leading to CE practices. Further, the study also depicts the CE practices leading to the select SDGs (“SDG 6: Clean Water and Sanitation,” “SDG 7: Affordable and Clean Energy,” “SDG 9: Industry, Innovation and Infrastructure,” “SDG 12: Responsible Consumption and Production” and “SDG 13: Climate Action”). The study proposes a conceptual framework based on the linkages above, which can help organizations to realign their management practices, thereby achieving specific SDGs.

The originality of the study is substantiated by a unique I-4.0-sustainable operations-CE-SDGs (ISOCES) framework that integrates I-4.0 and CE for sustainable development. The framework is unique, as it is based on an in-depth and systematic review of the literature that maps the links between I-4.0, CE and sustainability.

This study is an effort to explore a relationship between benefits of schemes (BoS) on the job satisfaction among handloom weavers. The weavers who are engaged in this work however face lot of challenges in terms of remuneration and working conditions. The government has been immense with various schemes that cater to the work-related problems. This paper aims to understand whether work-related support can be a predictor for job satisfaction in this context.

A cross-sectional survey design was used where 335 handloom weavers randomly participated in the study. Questionnaire was administered and scale was developed and validated for the measurement of BoS by using exploratory factor analysis and confirmatory factor analysis. The effect of the benefits on the job satisfaction was investigated by using structural equation modelling on AMOS 21 platform.

The outcome suggested that the BoS significantly affects the job satisfaction and a possible predictor. This which was indicated by the value of r^2, i.e.0.38 at significance level p < 0.001.

The study suggests a method for analyzing the schemes/policies in the light of the benefits that schemes intend to deliver. This would help in making suitable modifications in the schemes order to have wider outreach and large-scale inclusion of the beneficiaries.

The study can be useful for the policymakers to further strengthen the features of the schemes. They might work in direction of inclusion of more handloom weavers in the framework of the schemes.

The effects of the work-related policies on job satisfaction is still in nascent stage, so this work is all about exploration in that area.

The paper aims to convert into useable guidelines, the knowledge related to human factors and tasks' organisation, which are embedded in one of the most exciting maintenance actions that are carried out, the pitstop in Formula 1 races.

The paper opted for a fault tree analysis (FTA) to de-construct all the sub-tasks and their possible deviations from desirable situations and to evaluate the most relevant information needed for carrying out the pitstop operation. Besides, the SHELL model was applied in a second stage to evaluate the interaction between human being and human interfaces with other components of the system. Once this set of information was crystallised, the research translated it into useable guidelines for organising industrial maintenance actions using the same approach and possible reaching the same results.

The results of this study is a structured set of guidelines that encompasses the most paramount aspects that should be considered for setting correct maintenance actions. They represent a “guide” for including the different angles that are included during these operations.

The guidelines are potentially applicable to every maintenance operation. The guidelines should be tested on different working domains to check their applicability besides the racing world.

This study is a reverse engineering work for creating a scheme to include into maintenance operations aspects such as crew athlete-like fitness, training, technology, organisational issues, safety, ergonomics and psychology.

The value of the paper is deconstructing the results of one of the most successful and prepared maintenance action. The paper takes a different approach in proposing how to structure and create maintenance solutions. The difference in approaches between the maintenance during the pitstop of Formula 1 car and industrial applications enhances the gap that needs still to be filled for further improving maintenance actions out of the racing world.

The proposal is to answer the following question: based on previous studies, which are the new paths and challenges related to the circular economy (CE) and Industry 4.0 (I4.0)? To answer this question, the research objective is to analyze studies approaching the interface between CE and I4.0.

A systematic literature review (SLR) was conducted on previously published studies pertaining to Scopus and Web of Science bases, and 63 articles were found.

The authors present five new paths and challenges amid the relationship between CE and I4.0: applying those technologies to clean production, using blockchain and big data in the circular supply chain, raising additive manufacturing impact on the CE, seek for a better understanding on how I4.0 technologies can properly support the CE in the stakeholders' view and discerning the factors for implementing those theoretical fields onto supply chains.

Previous studies' sample basis is still recent, lacking research depth. Search strings might have minimized the number of selected studies: there could be a bigger sample.

Practical contributions of this study lay on the applicability of the raised propositions into several sectors' industries.

The authors suggest a transition agenda towards CE, using I4.0 technologies for operational, tactical and strategic personnel within organizations, as well as potential utilization strategies in specific study fields, like supply chain management and product manufacturing per se.

The study presents new paths and challenges amid technologies pertaining to I4.0 and its interfaces with the CE. In the result presentation and analysis, the existing interfaces are described.
