The literature on cavitation chemistry is ripe with conjectures, possibilities, heuris tic arguments, and intelligent guesses. The chemical effects of cavitation have been explained by means of many theories, consisting of empirical constants, adjustable parameters, and the like. The chemists working with cavitation chemistry agree that the phenomenon is very complex and system specific. Mathematicians and physi cists have offered partial solutions to the observed phenomena on the basis of cavitation parameters, whereas chemists have attempted explanations based on the modes of reaction and the detection of intermediate chemical species. Nevertheless, no one has been able to formulate a unified theme, however crude, for its effects on the basis of the known parameters, such as cavitation and transient chemistry involving extremely high temperatures of nanosecond durations. When one surveys the literature on cavitation-assisted reactions, it is clear that the approach so far has been "Edisonian" in nature. While a large number of reactions have showed either enhanced yields or reduced reaction times, many reactions have remained unaffected in the presence of cavitation. The success or failure of cavitation reactions ultimately depends on the collapse of the cavity. Cavitation chemistry is based on the principles of the formation of small transient cavities, their growth and implosion, which produce chemical reactions caused by the generation of extreme pressures and temperatures and a high degree of micro turbulence.

The Agent in the Margin: Nayantara Sahgal’s Gandhian Fiction is a comprehensive study of the literary works of Nayantara Sahgal, daughter of Vijaya Lakshmi Pandit—the first woman president of the United Nations General Assembly—and niece of Jawaharlal Nehru, India’s first prime minister. Clara A.B. Joseph introduces Mahatma Gandhi’s political and philosophical to literary analysis and utilizes non-structuralist aspects of Louis Althusser’s theories of ideology to trace how characters marginalized by gender, class, race, and language in Sahgal’s work assume agency, challenging poststructuralist theories of cultural and ideological determinism. She considers how gender complicates autobiography and how the roles of daughter, virgin, wife, widow, and alien serve (often ironically) to highlight human dignity.
Indian Shield: Precambrian Evolution and Phanerozoic Reconstitution highlights unique evolutionary trends covering a period of over 3,500 million years, from the oldest crust to the most recent geological activity of the Indian Subcontinent. The book discusses regional terrain geology in terms of the evolutionary history of the crust, describing how the Precambrian Shield evolved from a stable continental region to a tectonically unstable zone marked by frequent high-intensity earthquakes in a Plate-interior setting. It is a complete and readable account of the history of growth and evolution of the Indian Subcontinent, including Bangladesh, Bhutan, India, Nepal and Pakistan. The book is intended for graduate students, researchers, and teachers in the geosciences, especially geophysics, geomorphology and geology. The book also serves as an important resource for tectonics and petrology researchers, as well as those involved in exploration of mineral resources. Features comprehensive geological information on the evolution of the Indian Subcontinent, from the growth of early crust to the present day in a single volume Discusses different processes of post-Precambrian reconstitution of the Indian Shield that ultimately produced the present-day geomorphology as well as the tectonic character of the region Assesses the impacts and effects of the ongoing post-Himalayan tectonism on the Indian Subcontinent
The book will help the future earth scientists to identify potential horizons of future research work not only to enhance our knowledge but also to provide clues to finding new mineral deposits in this paradise for geologists.
The intellectual and cultural efflorescence in Goa reached its apogee in the late nineteenth and early twentieth centuries. Antonio Bernardo de Bragana Pereira was a product of this time, and Ethnography of Goa, Daman and Diu is an expression of the author passionate interest in scholarship and research into various dimensions of Goan life. His intellectual curiosity and critical spirit led him to delve deep to understand the lan vital of the society of his ancestors and to catalogue the many dimensions of Goan life. In the book he describes the rituals, customs and manners of various castes and religions, their habitat, their artisanship, their environment and all aspects of Goa and Goan society. Ethnography of Goa, Daman and Diu was published as a two-volume edition in 1940 in Portuguese. In making the second volume available to a larger readership, the publishers perform a dual role of bringing this scholarly work to a new generation of readers and in a language that will be accessible. Its publication is a tribute to A.B. de Bragan.a Pereiras passionate attachment to Goa and his pride in being a Goan.
Can "green petroleum" reverse global warming and bring down high gasoline prices? Written in non-technical language for the layperson, this book investigates and details how the oil and gas industry can "go green" with new processes and technologies, thus bringing the world's most important industry closer to environmental and economic sustainability. This book unravels the mysteries of the current energy crisis and argues that solutions to global warming will come only from the development of new technologies. Discussed here are the reasons why petroleum operations, as they are now, are not sustainable; how each practice treads an inherently implosive path; and how each spells irreversible damage to the planet's ecosystem. Fossil fuel consumption is not the culprit; rather, the practices involved, from exploration to refining and processing, are responsible for the current damage to the environment.
The Future of Petroleum Operations This state-of-the-art text analyzes some of the most contentious issues in the energy industry, covering new and greener processes for engineers and scientists and urging them to move petroleum operations closer to sustainability. Although petroleum is still the world's most diverse, efficient, and abundant energy source, there is a growing initiative from global political and industry leaders to "go green," because of climate concerns and high gasoline prices. This book investigates and details how to do that. This groundbreaking new volume: Explains why current petroleum industry practices are inherently unsustainable and offers unique new solutions for "greening" the petroleum industry Discusses hot-button issues, such as global warming, carbon sequestration, zero-waste management, and sustainability Shows engineers and scientists how to implement the processes necessary to be more environmentally conscious Offers, for the first time, a new theory that certain carbons do not contribute to global warming, but their origin and the processes involved do Praise for The Greening of Petroleum Operations "The book proposes a paradigm shift in energy management. It correctly identifies root causes of environmental impact of current petroleum production operations. With proper science, the book shows that fossil fuel production and utilization are inherently sustainable as long as natural materials and energy sources are used.... This book has the potential of revolutionizing energy management practices." —Farouq Ali, Honorary Professor of Oil and Gas Engineering, University of Calgary
