Bright gamma-ray flares observed from sources far beyond our Milky Way Galaxy are best explained if enormous amounts of energy are liberated by black holes. The highest- energy particles in nature--the ultra-high-energy cosmic rays--cannot be confined by the Milky Way's magnetic field, and must originate from sources outside our Galaxy. Understanding these energetic radiations requires an extensive theoretical framework involving the radiation physics and strong-field gravity of black holes. In High Energy Radiation from Black Holes, Charles Dermer and Govind Menon present a systematic exposition of black-hole astrophysics and general relativity in order to understand how gamma rays, cosmic rays, and neutrinos are produced by black holes. Beginning with Einstein's special and general theories of relativity, the authors give a detailed mathematical description of fundamental astrophysical radiation processes, including Compton scattering of electrons and photons, synchrotron radiation of particles in magnetic fields, photohadronic interactions of cosmic rays with photons, gamma-ray attenuation, Fermi acceleration, and the Blandford-Znajek mechanism for energy extraction from rotating black holes. The book provides a basis for graduate students and researchers in the field to interpret the latest results from high-energy observatories, and helps resolve whether energy released by rotating black holes powers the highest-energy radiations in nature. The wide range of detail will make High Energy Radiation from Black Holes a standard reference for black-hole research.
The effect of nutrition on the vital process of brain development has received increased attention in the last two decades. Using animal models, experimental research scientists have accumulated a wealth of infor mation and epidemiological studies of field workers have brought the animals and human studies together. Most times, there is an agreement on the results of animal and human experiences, but occasionally a voice of uncertainty is heard when results of animal studies are extrapolated to humans. After all, the human brain is far more complex than that of other species, and comparisons are not always accurate. Behavioral sci entists have attempted to correlate the findings of the biochemists and neurochemists to the "working" of the brain. Severe effects of malnutrition on body growth and function can usually be reversed by corrective procedures. But when such effects include the impact on brain development, the outcome can be devas tating. Underdevelopment of the brain caused by malnutrition during early life may not respond to corrective measures in later life. Undoubt edly this is a very controversial issue and the final verdict has not been reached. Unfortunately, even with today's tremendous technological innovations and applications, there are millions of people, including infants and children, who cannot obtain adequate food and are therefore exposed to damaging effects on the orderly development of the central vii PREFACE viii nervous system. Thus, this is a critical issue to many struggling popu lations who can ill afford such deprivation.
This book provides a comprehensive account of fiber-optic communication systems. The 3rd edition of this book is used worldwide as a textbook in many universities. This 4th edition incorporates recent advances that have occurred, in particular two new chapters. One deals with the advanced modulation formats (such as DPSK, QPSK, and QAM) that are increasingly being used for improving spectral efficiency of WDM lightwave systems. The second chapter focuses on new techniques such as all-optical regeneration that are under development and likely to be used in future communication systems. All other chapters are updated, as well.
Inlays of Subjectivity is an incisive exposition of the theme of subjectivity and selfhood in modern Indian literature. Scholarship in Indian literary studies tends to be divided along the lines of region, language, chronology, class, and caste. This book traverses and connects these contentious lines to examine some of the most influential literary texts to emerge from India in the last hundred years. It analyses literary expressions of intense emotionality—suffering, humiliation, creativity, and strife—while inhabiting the linkages between justice, speech, and affect. Nikhil Govind interprets a range of influential novelists such as Rabindranath Tagore and Saratchandra Chatterjee (Bengali), Agyeya (Hindi), Ismat Chughtai (Urdu), Krishna Sobti (Hindi), Urmila Pawar (Marathi), and K.R. Meera (Malayalam), to unearth narrative continuities of reflexive subject positions in relation to ongoing debates around free speech and egalitarianism.
The absence of water supply infrastructure is a critical issue that affects the sustainability of cities in the developing world and the quality of life of millions of people living in these cities. Urban India has probably the largest concentration of people in the world lacking safe access to these infrastructures. This book is a unique study of the politics of water supply infrastructures in three metropolitan cities in contemporary India – Bangalore, Chennai and Kochi. It examines the process of change in water supply infrastructure initiated by notable Public Private Partnership’s efforts in these three cities to reveal the complexity of state-society relations in India at multiple levels – at the state, city and neighbourhood levels. Using a comparative methodology, the book develops as understanding of the changes in the production of reform water policy in contemporary India and its reception at the sub-national (state) level. It goes on to examine the governance of regimes of water supply in Bangalore, Chennai and Kochi, and evaluates the role of the partnerships in reforming water supply. The book is a useful contribution to studies on Urban Development and South Asian Politics.
Between Love and Freedom interprets the figure of the revolutionary in the Hindi novel by establishing its lineage in representative Bengali novels, as well as in the contending moralities of Mahatma Gandhi and Bhagat Singh on the idea of violence. It reveals how conventional social realism and emergent modernist modes were brought together in the novelistic tradition by extending the political ideal of anti-colonial revolution into domains of sexual desire and subjective expression, especially in the works of Agyeya, Jainendra, and Yashpal. This work will deeply interest scholars and students of literature, modern Indian history, Hindi, and political science.
Witch hunts are the result of gendered, cultural and socioeconomic struggles over acute structural, economic and social transformations in both the formation of gendered class societies and that of patriarchal capitalism. This book combines political economy with gender and cultural analysis to explain the articulation of cultural beliefs about women as causing harm, and struggles over patriarchy in periods of structural economic transformation. It brings in field data from India and South-East Asia and incorporates a large body of works on witch hunts across geographies and histories. Witch Hunts is a scholarly analysis of the human rights violation of women and its correction through changes in beliefs, knowledge practices and adaptation in structural transformation.
An examination of the process of prioritizing private motorized transportation in Bengaluru, a rapidly growing megacity of the Global South. Automobiles and their associated infrastructures, deeply embedded in Western cities, have become a rapidly growing presence in the mega-cities of the Global South. Streets once crowded with pedestrians, pushcarts, vendors, and bicyclists are now choked with motor vehicles, many of them private automobiles. In this book, Govind Gopakumar examines this shift, analyzing the phenomenon of automobility in Bengaluru (formerly known as Bangalore), a rapidly growing city of about ten million people in southern India. He finds that the advent of automobility in Bengaluru has privileged the mobility needs of the elite while marginalizing those of the rest of the population. Gopakumar connects Bengaluru's burgeoning automobility to the city's history and to the spatial, technological, and social interventions of a variety of urban actors. Automobility becomes a juggernaut, threatening to reorder the city to enhance automotive travel. He discusses the evolution of congestion and urban change in Bengaluru; the “regimes of congestion” that emerge to address the issue; an “infrastructurescape” that shapes the mobile behavior of all residents but is largely governed by the privileged; and the enfranchisement of an “automotive citizenship” (and the disenfranchisement of non-automobile-using publics). Gopakumar also finds that automobility in Bengaluru faces ongoing challenges from such diverse sources as waste flows, popular religiosity, and political leadership. These challenges, however, introduce messiness without upsetting automobility. He therefore calls for efforts to displace automobility that are grounded in reordering the mobility regime, relandscaping the city and its infrastructures, and reclaiming streets for other uses.
