The essays included in this volume explore the interconnections between society, economy, religion and state, and their interaction with political processes in medieval India. This is a valuable reference source for all students and scholars of Mughal history, bringing together the various strands of a lifetime of work by a renowned medievalist.

Railway Engineering has been specially designed for undergraduate students of civil engineering. From fundamental topics to modern technological developments,the book covers all aspects of the railways including various modernization plans covering tracks, locomotives, and rolling stock. Important statistical data about the Indian Railways and other useful information have also been incorporated to make the coverage comprehensive. A number of illustrative examples supplement text to aid easy understanding of design methods discussed. The book should also serve the need of students of polytechnics and those appearing of the AMIE examination and would also be a ready reference for railway professionals.

The nature of the Indian state and policy, changing composition of the ruling class, and the developments in society and economy are the significant themes explored in this volume. It examines the evolution of the state in India and the role of the towns in the Orient; the Indian Historical tradition including the maritime narratives as well as the tradition of cultural pluralism--reflected in the Bhakti or Sufi movements in history--in the context of the unfolding of political processes in the fifty years after independence.

State, Pluralism, and the Indian Historical Tradition

This collection of seminal essays, by one of the most eminent historians and educationists, provides a comprehensive view of medieval India. Satish Chandra explores four main themes-evolution of state, role of towns and urbanism, the historical and maritime traditions, and cultural pluralism. Towards the end of the volume, Chandra surveys the role of leading Indian historians in promoting a more critical and secular view of medieval India. In a concluding historical assessment of the last fifty years, he highlights the role India could play in a challenging world order.

The environmental aspects involved in the production and use of cement, concrete and other building materials are of growing importance. CO2 emissions are 0.8-1.3 ton/ton of cement production in dry process. SO2 emission is also very high, but is dependent upon the type of fuel used. Energy consumption is also very high at 100-150 KWT/ton of cement produced. It is costly to erect new cement plants. Substitution of waste materials will conserve dwindling resources, and will avoid the environmental and ecological damages caused by quarrying and exploitation of the raw materials for making cement. To some extent, it will help to solve the problem otherwise encountered in disposing of the wastes. Partial replacement of clinker or portland cement by slag, fly ash, silica fume and natural rock minerals illustrates these aspects. Partial replacement by natural materials that require little or no processing, such as pozzolans, calcined clays, etc., saves energy and decreases emission of gases. The output of waste materials suitable as cement replacement (slags, fly ashes, silica fumes, rice husk ash, etc.) is more than double that of cement production. These waste materials can partly be used, or processed, to produce materials suitable as aggregates or fillers in concrete. These can also be used as clinker raw materials, or processed into cementing systems. New grinding and mixing technology will make the use of these secondary materials simpler. Developments in chemical admixtures: superplasticizers, air entraining agents, etc., help in controlling production techniques and, in achieving the desired properties in concrete. Use of waste products is not only a partial solution to environmental and ecological problems; it significantly improves the microstructure, and consequently the durability properties of concrete, which are difficult to achieve by the use of pure portland cement. The aim is not only to make the cements and concrete less expensive, but to provide a blend of tailored properties of waste materials and portland cements suitable for specified purpose. This requires a better understanding of chemistry, and materials science. There is an increasing demand for better understanding of material properties, as well as better control of the microstructure developing in the construction material, to increase durability. The combination of different binders and modifiers to produce cheaper and more durable building materials will solve to some extent the ecological and environmental problems.

In spite of the increasing use and demand for lightweight aggregate concrete (LWAC), there is still a lack of adequate explanations to understand the mechanisms responsible for the strength and durability properties of LWAC. This book is written to give an overall picture of LWAC, from the historical background, aggregate production, proportioning and production of concrete, to applications in structures. Physical properties and chemical durability are described in detail. The physical properties include density, strength, shrinkage, and elasticity. Chemical durability includes resistance to acids, chloride ingress, carbonation, and freeze-thaw resistance. Fire resistance is also included, which is seldom considered, but is a very important aspect of the safety of the structure. Microstructure development and its relation to the durability properties of LWAC generally are not highlighted in the literature. The development of bonds, the microstructure with different binder systems, and different types of lightweight aggregates are explained. They show how lightweight aggregate concrete differs from normal weight concrete. The chapters on chloride ingress and freeze-thaw resistance are detailed because of the use of LWAC in offshore construction. The economical aspects of using LWAC are also reviewed. Emphasis is placed on the fact that although the cost of LWAC is high, the total cost of construction has to be considered, including the cost of transport, reinforcement, etc. When these are considered then LWAC becomes cheaper and attractive. The life cycle cost of the concrete is another consideration for calculating long-term savings on maintenance costs.

Reference

This broad-based, introductory reference provides excellent discussions regarding the hydration of Portland cement, durability problems in concrete, mechanisms of concrete deterioration, and interaction of polymers in concrete. It also covers properties of concrete with added polymers and practical applications of polymers in concrete. The historic background of polymers in building materials is examined, and a comprehensive comparison of natural vs. synthetic polymers is provided and conveniently summarized in a tabular format.

This book deals with the contemporary subject of perception of risk and its influence on accidents and disasters. The contents examine the conventional viewpoints on human errors, incubation of errors, complexity and organisational deviance as a cause for accidents. Work of Mary Douglas with regard to risk, Charles Perrow's work on the normal accident theory and Diane Vaughan's theory on normalisation of deviance are examined from a fresh perspective in this book. It also discusses prominent accidents in aviation, space, nuclear energy, automotive and healthcare, using the pandemic and Boeing 737 Max as a backdrop to study accidents and disasters. It further explores the background and similarities to these events and addresses the core issues such as the state of regulation, the worldview of the sociologists, and proposes that mental models of complex systems, avarice and risk for gain as other possibilities for accidents. Using the concept of nudge in behavioural economics and the Elinor Ostrom’s viewpoint on regulating for common good, it suggests a way forward through the High Reliability Organisation Theory (HRO) leading to enhanced risk perception. The book will be of interest to those who would like to understand the need to incorporate risk perception into regulation, engineers and scientists, professionals and policy makers working in the areas of disaster and risk management, technology areas like aviation, nuclear plants, space and healthcare, students of the sociology of risk and of course the general reader.
