The purpose of this paper is to assess the ground water quality and salinity issues in the fast developing coastal urban lands of two river basins of Thiruvananthapuram district, Kerala, South India.

In order to address the water quality of the basins, field sampling was conducted and the samples were analysed in the laboratory. A comparison with water quality standards was also made and the interpretations of the results were done using GIS and statistical tools.

The values of conductivity, chlorides and salinity show that the coastal areas of Neyyar and Karamana basins are severely affected by salinity intrusion in addition to the pollution problems. More than 90 per cent of the samples are with hardness lower than 100 mg/l. About 70 per cent of the study area is with calcium concentrations lower than 25 mg/l. The content of sulphate and magnesium in Poovar and Poonthura coastal stretches is found to be higher compared to other regions.

Since not much work has been published from the study area on these aspects, the hydrochemical characterization is a very important in deciphering the quality of ground water for its proper management. The water quality evaluation and salinity intrusion studies are very important for the future planning and development of this area.

Background: Insurance was discovered many centuries before Christ (BC). In the second and third millennia BC, Chinese and Babylonian traders traded risks. Insurance is now the backbone of the economy, but penetration is low in developing countries. Big data, internet of things (IoT), and InsurTech have recently ushered in the fourth industrial revolution in insurance.

Objective: This study examines the Indian challenges and solutions of using Big Data Analytics (BDA).

methodology: A SLR was used to extract themes/variables related to challenges and solutions in adopting BDA in the Indian insurance sector. Google Scholar was searched for relevant literature using keywords. Inclusion and exclusion criteria were used to filter the studies.

Findings: This study identified several barriers to BDA adoption in the Indian insurance industry. Policymakers could use the suggestions to improve insurance service delivery.

Practical implication: Insurers can understand the challenges, and accordingly, they can adopt the proposed solution in this study to enhance the insurance penetration in India.

The present study aims to investigate the influence of key factors on the success of women micro-entrepreneurs in select states of India.

An empirical study is carried out to understand the influence of the psychological, socio-cultural, skill and resource-related factors on the success of women entrepreneurs. To achieve the set goal, a comprehensive questionnaire is developed for collecting data and is analyzed using the t-test, the chi-square test and structural equation modeling.

The proposed model is validated using structural equation modeling, and the fitness values indicate that the model is fit to explain the entrepreneurial success of women entrepreneurs in India.

The result advocates that the participation of women entrepreneurs may be increased to not only improve national growth but also empower women in India.

In the context of the women micro-entrepreneurs, no such study covering such a vast area of India has been carried out.

Purpose – Informed by an intersectional perspective, this chapter examines how middle-class, immigrant Tamil (an Indian regional group) Brahmin (upper-caste) profess/ional women organize motherhood in the U.S., by identifying the arrangements of mothering they develop, and the conditions under which these emerge.Methodology/approach – Data is based on a year-long ethnography among Tamils in Atlanta, and multi-part, feminist life-history interviews with 33 first-generation, Tamil professional women, analyzed within a constructivist grounded theory method.Findings – Tamil immigrant motherhood emerges from the interplay of Tamil women's social location as an immigrant community of color in the U.S. and their agency. Paradoxically racialized as model minorities who are also culturally incommensurable with American society, Tamil women rework motherhood around breadwinning and cultural nurturing to mother for class and ethnicity respectively. They expand the hegemonic model of Tamil Brahmin motherhood beyond domesticity positioning their professional work as complementary to mothering, while simultaneously reinforcing hegemonic elements of mothers as keepers of culture, responsible for ethnic socialization of children. Mothering then enables them to engender integration into American society by positioning families as upwardly mobile, model minorities who are ethnic. This, however, exacts a personal toll: their limited professional mobility and reduced personal leisure time.Originality/value – By uncovering Tamil immigrant motherhood as structural and agentic, a site of power contestation between spouses and among Tamil women, and its salience in adaptation to America, this chapter advances scholarship on South Asians that under-theorizes mothering and that on immigrant parenting in which South Asians are invisible.

The study aims to explore how Soret and Dufour diffusions, thermal radiation, joule heating and magnetohydrodynamics (MHD) affect the flow of hybrid nanofluid (Al₂O₃-SiO₂/water) over a porous medium using a mobile slender needle.

To streamline the analysis, the authors apply appropriate transformations to change the governing model of partial differential equations into a group of ordinary differential equations. Following this, the authors analyze the transformed equations using the homotopy analysis method within Mathematica software, leading to the derivation of analytical solutions. This study investigates how changing values for porous medium, MHD, Soret and Dufour numbers and thermal radiation influence concentration, temperature and velocity profiles. In addition, the research assesses the effects on local Sherwood number, skin friction and Nusselt number.

In this investigation, the authors explore the movement of a needle away from its origin ( ε > 0). As the magnetic and porous medium parameters increase, there is a correspondence decrease in the velocity profile. Simultaneously, an increase in the Dufour number and thermal radiation parameter yields to a higher temperature profile, whereas arise in the Soret number results in an enhanced concentration profile. Furthermore, growth in the magnetic field parameter is correlated with a reduction in skin friction, Nusselt and Sherwood numbers. In addition, an examination of the data reveals that an escalation in the thermal radiation parameter is associated with an elevation in the Nusselt number. Moreover, an elevation in the Dufour number results in an augmentation in the Nusselt number.

These results have practical applications across diverse fields, including heat transfer enhancement, energy conversion systems, advanced manufacturing and material processing.

This study is distinctive in its investigation of the flow of hybrid nanofluid (Al₂O₃-SiO₂/water) over a slender, moving needle. The analysis includes joule heating, MHD, porous medium, thermal radiation and considering the effects of Soret and Dufour.

This paper aims to study the impediments and difficulties that prevent Indian women from becoming entrepreneurs.

Data were obtained through a survey involving 15 experts. Based on the feedback provided by the experts, ten relevant barriers in the context of Indian micro small and medium enterprises (MSMEs) were chosen. A structured questionnaire was used to gather data. These ten barriers create obstruction for Indian women as entrepreneurs. These barriers were ranked, and causal relationships among them established using interpretive structural modeling and Matrice d’Impacts croises-multiplication appliqúean classment (cross-impact matrix multiplication applied to classification) (ISM–MICMAC) approach.

This study identifies, on the basis of extant literature and experts’ opinion, ten barriers to female entrepreneurship. These barriers were ranked, and causal relationships among them established using the ISM–MICMAC approach. On the basis of ranking, women can move forward in MSMEs after removing these obstacles and it will have good results.

In this research, with literature reviews and experts opinion, ten barriers have been identified for women’s entrepreneurship and have been used to build the model.

To bring Indian women forward in the field of entrepreneurship, both the society and the government should work together, and efforts should be made to overcome the obstacles coming in the way of entrepreneurs.

Female entrepreneurship in India faces many problems including negative attitude of authorities and society toward women. The society and authorities have no format or model for Indian women to move forward in the entrepreneurship sector.

This study seeks to identify, on the basis of a thorough review of literature and expert opinion, major barriers to female entrepreneurship in the context of Indian MSMEs.

This study aims to evaluate the suitability of Ferrock as a green construction material by analysing its engineering properties, environmental impact, economic viability and adoption challenges. It also aims to bridge knowledge gaps and provide guidance for integrating Ferrock into mainstream construction to support the decarbonisation of the built environment.

It presents a systematic and holistic review of existing literature on Ferrock, comprehensively analysing its mechanical properties, environmental and socio-economic impact and adoption challenges. The approach includes evaluating both quantitative and qualitative data to assess Ferrock’s potential in the construction sector.

Key findings highlight Ferrock’s superior mechanical properties, such as higher compressive and tensile strength, and enhanced durability compared to traditional Portland cement. Ferrock offers significant environmental benefits by capturing more CO₂ during curing than it emits, contributing to carbon sequestration and reducing energy consumption due to the absence of high-temperature processing. However, the material faces economic and technical challenges, including higher initial costs, scalability issues, lack of industry standards and variability in production quality.

This review provides a comprehensive and up-to-date analysis of Ferrock. Despite being discussed for a decade, Ferrock research has been overlooked, with existing studies often limited and published in poor-quality sources. By synthesising current research and identifying future study areas, the paper enhances understanding of Ferrock’s potential benefits and challenges. The originality lies in the holistic evaluation of Ferrock’s properties and its implications for the construction industry, offering insights that could drive collaborative research and policy support to facilitate its integration into mainstream use.

The case explores the growth of Dastkar Andhra Marketing Association (DAMA) and its relationship with its sister organizations, as it works to articulate an alternate model of production, distribution and retailing. The case attempts to highlight issues around appropriate interventions in a traditional sector providing livelihood to millions, but confronting the challenges of a modern economy and society. The case would be beneficial in emphasizing the role of market and state failures and the role played by social enterprises in addressing them.
