This book provides a comprehensive introduction to the theoretical and experimental studies of atomic optical bistability and multistability, and their dynamical properties in systems with two- and three-level inhomogeneously-broadened atoms inside an optical cavity. By making use of the modified linear absorption and dispersion, as well as the greatly enhanced nonlinearity in the three-level electromagnetically induced transparency system, the optical bistablity and efficient all-optical switching can be achieved at relatively low laser powers, which can be well controlled and manipulated. Until now, the rapid rate of progress in applications of multilevel systems in cross-disciplinary field has made it difficult to newcomers to the field to obtain a broad overview of this topic. This monograph will serve the purpose.
Throughout the twentieth century, biologists investigated the mechanisms that stabilize biological populations, populations which--if unchecked by such agencies as competition and predation--should grow geometrically. How is order in nature maintained in the face of the seemingly disorderly struggle for existence? In this book, Laurence Mueller and Amitabh Joshi examine current theories of population stability and show how recent laboratory research on model populations--particularly blowflies, Tribolium, and Drosophila--contributes to our understanding of population dynamics and the evolution of stability. The authors review the general theory of population stability and critically analyze techniques for inferring whether a given population is in balance or not. They then show how rigorous empirical research can reveal both the proximal causes of stability (how populations are regulated and maintained at an equilibrium, including the relative roles of biotic and abiotic factors) and its ultimate, mostly evolutionary causes. In the process, they describe experimental studies on model systems that address the effects of age-structure, inbreeding, resource levels, and population structure on the stability and persistence of populations. The discussion incorporates the authors' own findings on the evolution of population stability in Drosophila. They go on to relate laboratory work to studies of animals in the wild and to develop a general framework for relating the life history and ecology of a species to its population dynamics. This accessible, finely written illustration of how carefully designed experiments can improve theory will have tremendous value for all ecologists and evolutionary biologists.
The God Of Small Things, The International Best Seller By Arundhati Roy, Has Raised Numerous Questions. Is It A Piece Of Anti-Communist Propaganda? Does It Distort Social Reality? Is It A Cheap Imitation Of The Western Fashion In Novel? Does It Offer Nothing But Play With Words? The Present Book Examines The Novel Sociologically And Answers All These Questions Well.The Book Also Shows That The Novelist Cares For The Neglected In The Society Like Women, Children And Dalits And Even The Environment. She Conveys Messages So Relevant To Our Society And Our Age.
Offering a comprehensive, multidisciplinary approach to a complex topic, Foot and Ankle Pain Management is a first-of-its-kind reference to this commonly presenting problem. Drs. Rock G. Positano, Neel Mehta, Andrew J. Rosenbaum, and Amitabh Gulati provide authoritative clinical guidance from areas of expertise in musculoskeletal podiatry, pain medicine, physiatry, and orthopaedic surgery. This first-line resource covers relevant anatomy, pain conditions, and treatments in a well-organized, easily referenced manner—offering a complete approach to care for foot and ankle specialists, pain medicine specialists, primary care physicians, pediatricians, and other clinicians who encounter patients with foot and ankle pain.
First published in 1997, this study is one of the forerunners in the area of urban land market and land price studies on a Third World city, focusing on Lucknow City in Uttar Pradesh, India, and exploring house prices, economic changes and construction. Amitabh responds to the 2nd Habitat Conference of 1996, which realised that housing conditions for lower income group people in most Third World cities have not improved, especially with regards to tenure, affordability and overall housing quality.
Th e art of vernacular painting in India is not only varied and rich but also intriguing for several reasons. With such observations the book addresses certain issues, like the validity of the historical information on Indian Art that excludes vernacular trends. The information on vernacular art in India has either been ignored such as in ancient literary discourses or inadvertently misconstrued within the theoretical purviews of modern days. If the hierarchy of the Hindu caste system has marginalised the culture of the lower rung groups, the lexicon of twentieth century anthropological studies has seen this art as material evidence of undeveloped societies; both creating the same value: to be patronised but not art. Can art be weighed on a scale of development? Arguments have been developed within the specifi c focus on scroll paintings by the itinerant painter bards in Bengal. Th e bardic tradition has been known to exist in India since a pre-Christian era and still continues within two vibrant trends of vernacular art forms Bangla and Santhal pat. Th e book redefi nes and repositions the notion of art with contemporary folk art. As the picture Plates are self-evident, the book draws attention on a world of art that has not been present in Indian Art History.
