The most comprehensive account of the origin of ancient and modern birds—the "living dinosaurs." A small set of fossilized bones discovered almost thirty years ago led paleontologist Sankar Chatterjee on a lifelong quest to understand their place in our understanding of the history of life. They were clearly the bones of something unusual, a bird-like creature that lived long, long ago in the age of dinosaurs. He called it Protoavis, and the animal that owned these bones quickly became a contender for the title of "oldest known bird." In 1997, Chatterjee published his findings in the first edition of The Rise of Birds. Since then Chatterjee and his colleagues have searched the world for more transitional bird fossils. And they have found them. This second edition of The Rise of Birds brings together a treasure trove of fossils that tell us far more about the evolution of birds than we once dreamed possible. With no blind allegiance to what he once thought he knew, Chatterjee devours the new evidence and lays out the most compelling version of the birth and evolution of the avian form ever attempted. He takes us from Texas to Spain, China, Mongolia, Madagascar, Australia, Antarctica, and Argentina. He shows how, in the "Cretaceous Pompeii" of China, he was able to reconstruct the origin and evolution of flight of early birds from the feathered dinosaurs that lay among thousands of other amazing fossils. Chatterjee takes us to where long-hidden bird fossils dwell. His compelling, occasionally controversial, revelations—accompanied by spectacular illustrations—are a must-read for anyone with a serious interest in the evolution of "the feathered dinosaurs," from vertebrate paleontologists and ornithologists to naturalists and birders.
This book presents a groundbreaking hypothesis to answer one of the greatest scientific mysteries: How did life begin? Like a detective piecing together seemingly disparate bits of evidence, Dr. Sankar Chatterjee combines the most recent discoveries in cosmology, geology, chemistry, information systems, and biology, weaving a vast tapestry from the threads of current research. Dr. Chatterjee convincingly argues that the odyssey of life first began when the fundamental building blocks were brought to Earth by meteorites. These cosmic compounds concentrated and simmered like a soup in hydrothermal crater-caldrons. Through a system of subterranean vent networks, a biosynthetic-rich variety of organic compounds mixed and matched into a recipe of rich biomolecules guided by prebiotic information systems. Through symbiosis, these complex biopolymers gradually assemble into membrane-bound protocells. At each stage of this evolutionary progression, through natural selection, they refined with increasing stability and complexity, ultimately leading to the emergence of the first cells about four billion years ago. In this book, Dr. Chatterjee tells this story in rigorous detail in language that is both accessible and engaging.

GeoComputation and Public Health is fundamentally a multi-disciplinary book, which presents an overview and case studies to exemplify numerous methods and solicitations in addressing vectors borne diseases (e.g, Visceral leishmaniasis, Malaria, Filaria). This book includes a practical coverage of the use of spatial analysis techniques in vector-borne disease using open source software solutions. Environmental factors (relief characters, climatology, ecology, vegetation, water bodies etc.) and socio-economic issues (housing type & pattern, education level, economic status, income level, domestics’ animals, census data, etc) are investigated at micro -level and large scale in addressing the various vector-borne disease. This book will also generate a framework for interdisciplinary discussion, latest innovations, and discoveries on public health. The first section of the book highlights the basic and principal aspects of advanced computational practices. Other sections of the book contain geo-simulation, agent-based modeling, spatio-temporal analysis, geospatial data mining, various geocomputational applications, accuracy and uncertainty of geospatial models, applications in environmental, ecological, and biological modeling and analysis in public health research. This book will be useful to the postgraduate students of geography, remote sensing, ecology, environmental sciences and research scholars, along with health professionals looking to solve grand challenges and management on public health.
This book addresses the current challenges in controlling Kala-azar disease (Visceral leishmaniasis) in India and other VL-endemic areas, and aims to develop and apply a geo-environmental risk model based on primary and secondary data with the aid of remote sensing and GIS technologies to assess and mitigate Kala-azar transmission. Through case studies carried out in India, the book provides insight into the relationship between geo-environmental variables and encroachments of Kala-azar, and identifies potential pathways for VL introduction to develop mitigation strategies using GIS and remote sensing technologies. The book critically assesses existing VL mitigation measures that do not adequately account for geo-environmental conditions, and analyzes the environmental factors that aid Kala-azar transmission using remote sensing, spatial statistics and data mining techniques. The book will be of interest to epidemiologists, researchers and practitioners using geospatial data practices to study disease transmission and associated monitoring technologies.
The COVID-19 pandemic is posing hitherto the toughest challenge for humanity in the 21st century. Already with more than 63 million people in 218 countries around the world have infected by the pervasive conflagration of the contagion, the disease has unleashed system-altering effects. Obviously, it was a new situation for all of us when we saw not only differential response in different regions and on the part of different nation-states to cope with this humongous crisis but also the distribution of power was undergoing a sea change that required a new analysis. In the case of India we witnessed her excellent outreach in terms of medical diplomacy and HADR missions, her resilience to Chinese belligerence and her altruistic concern for the members of the SAARC, to mention a few. Put in this background the focus of this book is on emerging contours of Indian foreign policy in new normal from virtual diplomacy to the trends of greater geopolitical tensions and global power shift at large.

At the outset, the author of the book welcomes his supervisor Prof. Prof (Dr.) G. S. Roy who has joined me as coauthors of this text, a credit which would have been given earlier to them as they were helping in a latent way in the evolution of the book for the past five years. Five years have elapsed on the intellectual journey of writing a PhD thesis e-book in title “Hall Effect on the Magnetohydrodynamic Flow of Some Newtonian and Non-Newtonian Conducting Fluids” in subject of physics. As Magnetohydrodynamic Flow is growing at a dazzling pace, this edition has been demanding in a different way. In this 1st edition, the book has been thoroughly described, enlarged and updated with Magnetohydrodynamic Flow. Gratitude is expressed to the students and teachers, both from India and abroad, who have sent in their valuable suggestions which have been given due consideration. We are sincerely thankful to our publisher, Newredmars Education. We are also deeply indebted to my guide Prof. Dr. G. S. Roy for his sustained support of this endeavour from its inception; his wisdom has made all the difference. Healthy criticism and suggestions for further improvement of the book are solicited.
