This book focuses on the surface plasmon resonance (SPR) technique covering fibre optic sensor research. It highlights recent advancements in geometric feature-based fibre optic SPR sensors for chemical/biochemical/biosensor applications. The contents also discuss the principle of the SPR sensing technique as well as various designs of fibre optic SPR probes for improving sensor sensitivity. It also includes numerous examples of SPR-based fibre optic sensors with various geometric (such as U-type, taper type, D-type, and interferometric-based) sensors. This volume will be a useful reference to those in academia and industry especially researchers with useful information focusing on fibre optic SPR sensors.

Women, and particularly poor women, have become essential cogs in the wheel of financialized capitalism. Globally, women are responsible for managing household debt, and that debt has exploded over the last decade, reaching an all-time high after the COVID-19 pandemic. Across various categories of loans, including subprime lending, microcredit policies, and consumer loans, as well as rent and utilities, women are overrepresented as clients and managers, and are being enfolded into the system. The Indebted Woman discusses the crucial yet invisible roles poor women play in making and consolidating debt and credit markets. Isabelle Guérin, Santosh Kumar, and G. Venkatasubramanian spent over two decades observing a credit market that specifically targets women in the Indian countryside of east-central Tamil Nadu. They found that paying off debts required labor, frequently involved sexual transactions, and shaped women's bodies and subjectivities. Bringing together ethnography, statistical surveys, and financial diaries, they offer for the first time a comprehensive theory for this sexual division of debt that goes far beyond the Indian case, exposing the ways capitalism transforms womanhood and how this transformation in turn fuels capitalism.

This book provides a comprehensive insight into the growth of nanotechnology in the agri-food industry. Currently, nanotechnology serves as the most promising means to resolve the issues encountered in the food sector, as it enables the production of high-quality food with exceptional characteristics such as extended shelf life, flavor, freshness, and high nutritional content. This book focuses on the applications of nanotechnology in various fields such as smart packaging, processing, and preservation of food. It also emphasizes the role of nanomaterials in strategic design of nutraceuticals and functional foods. Along with providing an overview of the innovations and application, this book also describes future perspectives, and offers insights to ensure consumer confidence in terms of safe use. In this context the application of nanomaterials as nanosensors is additional covered. The book provides readers with a deep knowledge regarding nanomaterials-based biosensors (colorimetric,electrochemical, fiber-based) for detection of pathogens in contaminated food. Factors affecting risk assessment regulations and safety concerns regarding the use of nanomaterials in food industry have also been discussed in detail. Given its scope, this book appeals to a wider readership, especially for researchers and students who work in food agronomy and nanomaterials and nanotechnology related fields.

In thermal power plants, coal fired boilers are commonly used due to its low cost. However, the premature failure of boiler parts is a common problem. These boilers mostly fail during operation due to oxidation, corrosion and E-C at high temperature and lead to big economic losses. The hot corrosion and erosion-corrosion alone has been reported to be responsible for 50% to 75% of entire arrest time in such applications and leads to multi-million dollar loss to the power generating industries. This problem should be addressed by the researchers. Hence, this book provides in depth review of high temperature materials, material degradation, high temperature oxidation, corrosion, erosion-corrosion & their protective measures. These protective methods include: proper selection of material, potential change of metal, corrosion inhibitors, change of environment and coating.

At the very outset, a theoretical environment has been set to describe the women entrepreneurship and microfinance. The socio-economic status of women entrepreneurs has been discussed in the second chapter. The third chapter discusses on how the women entrepreneurship through microfinance activities alleviates poverty and impacts the socio-economic status of women entrepreneurs. The suggestions and the conclusions are elaborated in the last chapter. It is hoped that a research of this nature, oriented would provide an in-depth insight into the socio-economic status of women entrepreneurs and also the problems that are encountered by the microfinance schemes. This research would also be helpful for the Government, the Non-Governmental Organizations (NGOs), and the Micro-Financial Institutions (MFIs) in formulating a specific policy for the development of women entrepreneurship through microfinance activities.
