This paper aims to study the suitability of a selection of 3D printing liquid photopolymer resins for their application in the cultural heritage context.

The main concerns regarding the conservation and restoration of cultural assets are the chemical composition and long-term behavior of the new materials that will be in contact with the original object. Because of this, four different LED curing resins were exposed to an accelerated aging procedure and tested to identify the materials which demonstrated a better result. Some specific properties of the material (color, glossiness, pH and volatile organic compound emissions) were measured before and after the exposure.

Some of the properties measured reported good results demonstrating a decent stability against the selected aging conditions. The main changes were produced in the colorimetric aspect, probably indicating other chemical reactions in the material. Likewise, a case study could be also executed to demonstrate the usefulness of these materials in the cultural field.

It is necessary to study in more detail the long-lasting behavior of the materials employed with these technologies. Further analysis should be carried out highlighting the chemical composition and degradation process of the materials proposed.

This paper contributes to the introduction of curing 3D printing resins in the restoration methodologies of cultural assets. For this, the study of a selection of properties represents the first stage to suggest or reject their use.

Purpose: This study examines how corporate social responsibility (CSR) affects Tata enterprises’ financial performance. Numerous studies have examined how CSR affects company FP, with mixed results. The large variety of outcomes may have been due to erroneous analysis or insignificantly controlled variables, but the most likely explanation is that different research utilised different approaches. This study examines the relationship between CSR and financial performance in India using Tata Group companies listed on the BSE100.

Methodology: The BSE100-listed Tata companies were chosen for investigation because Tata's are pioneer in philanthropy and CSR. The present investigation relies on data obtained from annual reports and sustainability reports of the respective companies for a period of 10 years (2013–2022). Regression analysis was performed using Stata version 14 to evaluate the relationship between CSR spending and financial performance.

Research limitation: The study is confined to 7 Tata companies indexed in the BSE100 for 10 years (FY2013–FY2022).

Social implication: Tata companies’ ethics and philanthropy activities are landmarks in Indian society that can be used to motivate the business stakeholders to contribute more to CSR. The tourism companies can use Tata's CSR model to grow their financial performance.

Findings: The findings of the study depict that financial performance is positively impacted by the amount spent on CSR by the companies. Companies that invest more in CSR have higher profitability, ROA, ROE, EPS, MB Ratio and MR_Daily.

Originality: This chapter will add comprehensive knowledge about the relationship of CSR and financial performance.

This research explores the antecedents of tourist satisfaction and revisit intention, especially in light of the post-pandemic environment that pushed tourism to the lowest level in the present decade. A comprehensive conceptual model based on the brand equity theory (BET) is developed, and interrelationships between brand heritage, community support and benefits, hedonism, culture, tourist satisfaction and revisit intention.

The data were collected from 670 tourists visiting one of the heritage destinations in southern India (Kanchipuram). After checking the psychometric properties of the survey instrument, the hypotheses were tested using path analysis and Hayes's PROCESS macros.

The results indicate that heritage brand of destination sites is positively associated with (1) tourist satisfaction and (2) tourist revisit intention. The findings also support the positive effect of attractiveness of products is positively related to tourist satisfaction, which in turn, is a significant predictor of tourist revisit intention. The findings also support that community support benefits moderating the relationship between heritage brand and attractiveness of products in heritage destinations tourist satisfaction.

This study has several implications for practicing managers engaged in maintaining heritage destinations. As this research highlights the importance of heritage brands of destinations in influencing tourist satisfaction, local communities and policymakers need to provide the necessary infrastructure and facilities at these destinations. Further, local entrepreneurs are motivated to invest in delivering products that attract tourists.

The conceptual model developed in this study, is first of its kind, to the best of the authors’ knowledge, that investigates the effect of hedonism (second moderator) moderating the relationship between tourist satisfaction and culture (first moderator) in influencing tourists to revisit their intention. In addition to direct relationships, the moderating role of community support and benefits, culture and hedonism makes a unique contribution to the bourgeoning literature on tourism especially in Indian context.

The main objective of the paper is to find evidence of abnormal returns and performance persistence of actively managed equity funds in the Indian context on an annual basis during the post-subprime crisis period between 2009 and 10 and 2019 and 2020.

The study is exploratory and empirical, used daily net asset value (NAV) of 180 equity funds for 10 years and applied the risk-adjusted, Jensen's (1968) single-factor, Fama and French's (1993) three-factor model and Carhart's (1997) four-factor model to evaluate the performance. The performance persistence has been tested using cross-section regression (Bollen and Busse, 2005), the non-parametric contingency approach, along with the robustness measure, i.e. Malkiel's (1995) Z-score, Brown and Goetzmann's (1995) cross-product ratio (CPR) and Kahn and Rudd's (1995) χ² value.

The results show that the Indian equity funds are unable to generate abnormal returns, and the size, value and momentum strategies applied by the fund managers in generating abnormal returns do not work effectively. However, funds provide strong evidence of significant performance persistence on an annual basis in the short-term, mid-term and long-term periods. Both parametric as well as non-parametric tests provide identical evidence of persistence, and the performance persistence is independent of the choice of models, as all the models (i.e. two, three or four-factor models) provide significant evidence of persistence.

Though the study is comprehensive and covered a longer period, there is a scope for future research by examining the influence of fund characteristics, fund rating and macroeconomic factors on performance and persistence. It can be extended over to a longer period covering the post-COVID-19 period, a larger sample size and a comparative study of Indian and foreign mutual funds (MFs).

The outcomes of this research paper can help wealth-maximizing investors in the identification of persistent equity funds and can apply the previous period’s performance information as a useful investment strategy to generate higher returns in the future. We believe that these outcomes will have significant ramifications for all MF stakeholders and policymakers, especially for the Indian industry in ensuring and establishing the credibility of MF managers, in providing better returns as well as to make MF investment more attractive to Indian retail investors.

Despite the exponential growth in the Indian MF industry, limited evidence is available on performance and persistence covering a large sample size during the post-sub-prime crisis period using different return models and parametric and non-parametric approaches. The study is based on the daily data set of a larger sample size representing all the Asset Management Company (AMC) and the longer period following the post-subprime crises, which affected capital flows significantly. Moreover, the application of all the measures enables us to understand performance persistence in a larger context.

This study aims to assess the effect of water variation on bioethanol production from cassava peels (CP) using Saccharomyces cerevisiae yeast as the ethanologenic agent.

The milled CP was divided into three treatment groups in a small-scale flask experiment where each 20 g CP was subjected to two-stage hydrolysis. Different amount of water was added to the fermentation process of CP. The fermented samples were collected every 24 h for various analyses.

The results of the fermentation revealed that the highest ethanol productivity and fermentation efficiency was obtained at 17.38 ± 0.30% and 0.139 ± 0.003 gL⁻¹ h⁻¹. The study affirmed that ethanol production was increased for the addition of water up to 35% for the CP hydrolysate process.

The finding of this study demonstrates that S. cerevisiae is the key player in industrial ethanol production among a variety of yeasts that produce ethanol through sugar fermentation. In order to design truly sustainable processes, it should be expanded to include a thorough analysis and the gradual scaling-up of this process to an industrial level.

This paper is an original research work dealing with bioethanol production from CP using S. cerevisiae microbe.

The purpose of this study is to extract and characterize a novel natural dye from the leaves of Lannea coromandelica and the extraction with finding ways of dyeing cotton fabric using three mordants.

The colouring agents were extracted from the leaves of Lannea coromandelica using an aqueous extraction method. The extract was characterized using analysis methods of pH, gas chromatography-mass spectrometry (GC-MS), Fourier transform infrared (FTIR), ultraviolet-visible (UV-vis) and cyclic voltammetry measurement. The extract was applied to cotton fabric samples using a non-mordant and three mordants under the two mordanting methods. The dyeing performance of the extracted colouring agent was evaluated using colour fastness properties, colour strength (K/S) and colour space (CIE Lab).

The aqueous dye extract showed reddish-brown colour, and its pH was 5.94. The GC-MS analysis revealed that the dye extract from the leaves of Lannea coromandelica contained active chemical compounds. The UV-vis and FTIR analyses found that groups influenced the reddish-brown colour of the dye extraction. The cyclic voltammetry measurements discovered the electrochemical properties of the dye extraction. The mordanted fabric samples showed better colour fastness properties than the non-mordanted fabric sample. The K/S and CIE Lab results indicate that the cotton fabric samples dyed with mordants showed more significant dye affinities than non-mordanted fabric samples.

Researchers have never discovered that the Lannea coromandelica leaf extract is a natural dye for cotton fabric dyeing. The findings of this study showed that natural dyes extracted from Lannea coromandelica leaf could be an efficient colouring agent for use in cotton fabric.
