Natural Convection in Composite Fluid-Porous Domains provides a timely overview of the current state of understanding on the phenomenon of convection in composite fluid-porous layers. Natural convection in horizontal fluid-porous layers has received renewed attention because of engineering problems such as post-accident cooling of nuclear reactors, contaminant transport in groundwater, and convection in fibrous insulation systems. Because applications of the problem span many scientific domains, the book serves as a valuable resource for a wide audience.
This much anticipated volume looks at the historical evolution of towns and cities in medieval India from the early thirteenth to the late eighteenth century. The selection is based on the availability of documents. These include the narratives of European travellers in English, French, Italian, Dutch, and German with the exception of Ibn Battuta in mid-fourteenth century and also Middle Bengali literature in case of towns in Bengal. While the coastal towns and cities have been looked at, the interior ones are also described on the basis of the writings of later historians and archaeologists. Care has been taken to explain the rise, growth and the decline of some towns and cities in which the changing courses of rivers had played a crucial role. Attempts have been made to search other factors responsible for such eventualities. The delineation of physical features within the city has been given due emphasis including the different quarters of the city and the manners and customs of the local population with reference to craft production and commercial links. The morphological differences between the cities of eastern and those of the western or northern India have also been described. This is clear from the observations of port towns described here. All these would show that India was one of the most urbanized area in the medieval period before advent of the British.
Aniruddha Ray retired as Professor of History, from the Department of Islamic History and Culture, University of Calcutta, Kolkata, West Bengal. Well known for his profound interest in historical research, Aniruddha Ray has written extensively about Mughal administration, technology and travelogues; the society and culture of Medieval Bengal; the economic history of the Sultanate and Mughal periods; overseas trade and merchants; and the French East India Company on the basis of a fine blending of his knowledge of Bengali, English and French sources. As a mark of esteem and affection, scholars in India and abroad have joined hands to offer him this volume. The festschrift reflects the range of Aniruddha Ray's interests and influences in some measure. The theme of the present volume includes the contemporary effort within academia to question the traditional representation of Indian history and the attempts in various areas of study to de-centre the writing of history, and to provide an alternative perspective to the history of fifteenth to nineteenth-century India. In this eclectic collection of essays one can see an innovative approach at work, which raises interesting questions when one situates these ideas and the historical evidence within the big picture, as one moves back and forth between the macro-perspective and the micro-history addressed in most of these essays. With eminent historians of the subcontinent contributing to it, The Varied Facets of History: Essays in Honour of Aniruddha Ray throws new light on aspects of Indian history: its sources and their interpretations, the evolution of cultural aspects like languages especially Hindi and Bengali, archaeology, painting, technology, trade and commerce and labour.
This book highlights the need for studying multi-state models analytically for understanding the physics of molecular processes. An intuitive picture about recently solved models of statistical and quantum mechanics is drawn along with presenting the methods developed to solve them. The models are relevant in the context of molecular processes taking place in gaseous phases and condensed phases, emphasized in the introduction. Chapter 1 derives the arisal of multi-state models for molecular processes from the full Hamiltonian description. The model equations are introduced and the literature review presented in short. In Chapter 2, the time-domain methods to solve Smoluchowski-based reaction-diffusion systems with single-state and two-state descriptions are discussed. Their corresponding analytical results derive new equilibrium concepts in reversible reactions and studies the effect of system and molecular parameters in condensed-phase chemical dynamics. In Chapter 3, time-domain methods to solve quantum scattering problems are developed. Along side introducing a brand new solvable model in quantum scattering, it discusses transient features of quantum two-state models. In interest with electronic transitions, a new solvable two-state model with localized non-adiabatic coupling is also presented. The book concludes by proposing the future scope of the model, thereby inviting new research in this fundamentally important and rich applicable field.
This book provides an integrated view of the Delhi Sultanate government from 1206 to 1526. It is divided into two parts. The first part deals with the political events and the dynastic history of the Sultans and the second part with the administration, different land issues, social life including two major religious movements and other cultural aspects including architecture and sculpture. The growth of the city of Delhi has been shown here perhaps for the first time. Most of the books on Delhi Sultanate mainly narrate the political events. Here other aspects have been included to show the real character of the Sultanate. It may be mentioned that the English officials from the end of the eighteenth Century had termed the medieval period of India as a ‘dark age’ – a statement that has been accepted by several Indian writers. It is to negate this view that an integrated narrative has been provided here. Please note: Taylor & Francis does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka
Human Rights and the Third World: Issues and Discourses deals with the controversial questions on the universalistic notions of human rights. It finds Third World perspectives on human rights and seeks to open up a discursive space in the human rights discourse to address unresolved questions, citing issues and problems from different countries in the Third World: Whether alternative perspectives should be taken as the standard for human rights in the Third World countries? Should there be a universalistic notion of rights for Homo sapiens or are we talking about two diametrically opposite trends and standards of human rights for the same species? How far these Third World perspectives of human rights can ensure the protection of the minorities and the vulnerable sections of population, particularly the women and children within the Third World? Can these alternative perspectives help in fighting the Third World problems like poverty, hunger, corruption, despotism, social exclusion like the caste system in India, communalism, and the like? Can there be reconciliation between the Third World perspectives and the Western perspective of human rights?
