There are large numbers of books that present the theoretical aspects but there are no books in practical perspective. The present book looked in to the practical aspects pertaining to irrigation and irrigation projects. To achieve the sustainable development in irrigation and irrigation projects, the major hurdles are appointment of tribunals and settling the disputes. These play vital role in projects implementation and making them cost effective. The book discussed some of the basic problems in irrigation and irrigation projects in India in general and in Andhra Pradesh in specific. These issues are discussed with reference to Krishna River Water Disputes Tribunal and Polavaram project disputes on River Godavari. Also discussed, the issues related to interlinking of rivers in addition to several other issues including climate change & pollution aspects.

This Handbook on Materials Management for Healthcare is an adaptable reference book which provides sound and complete indispensable introduction and information to the materials function in healthcare industry. It includes descriptions of a wide variety of sub-topics and provides assessment tools such as checklists and specific action plans for improving operational performance. It provides a quick access to the working managers and hospital's administrators regarding everyday issues without having to do excessive research.This book will also be found extremely useful for students of Hospital Management as it equips them with the tools and techniques of materials management, inventory control, purchasing, store-keeping and supply chain management especially as they are applied to and practiced in the peculiar ecosystems prevalent in healthcare industry. It meets the syllabii requirements of almost all the universities and institutes which are conducting courses on Hospital administration. This book also addresses the concerns about costs, quality of patient care and treatment outcomes. Suitable exercise, model questions, numerical problems, hints and answers have been included to benefit the student community.Efforts have been made to strike a balance between the overview approach and the treatment of specific details. It is the first book of its kind in India about the healthcare industry.

The electrification is considered as the greatest engineering achievement of the 20th century. However, the beginning of the 21st century  has seen major changes in the ESI introduced by restructuring which has resulted in breaking up of  vertically integrated utilities(VIU). Competition has been introduced in power generation and power trading is encouraged.The technical problems facing system operation and control are expected to be solved by information and communication technology using smart grid solutions. However, innovative approaches are required to tackle the operational problems and continue to provide electrical energy reliably and at affordable costs. This requires a good understanding of the physical structure of electricity supply system and the knowledge of state of the art in the system operation and control. This book is designed to help non-electrical engineers to understand the overall picture and the relevant issues that need to be tackled.The book contains 9 chapters and 5 appendices. The reasons for power interruptions and blackouts are discussed in chapter 1. The electrical machinery (generators, motors and transformers), transmission and distribution are described in chapters 3 and 4. The basics of electrical circuits (that are used to model the various system components) are covered in chapter 2. The power system operation under normal conditions is discussed in chapter 5. The system protection and collapse, technological solutions and smart grid are described in chapters 6 and 7. The renewable power and energy storage systems are presented in chapter 8. Chapter 9 deals with restructuring and competition in ESI and suggests a roadmap for the future. The appendices cover the use of units, electric shocks and safety and nuclear energy.

Food chemistry plays a vital role in food industry because it helps Food Technologists to understand the components and behavior of food and nutritionists to develop healthy diets. The main aim of nutritional professionals now is to apply nutrition principles to promote health and well-being, to prevent disease and to restore health in individuals, families and community. To achieve this goal, application of various scientific principles of food and food processing is essential. This book "Food Chemistry and Nutrition: A comprehensive Treatise" presents the complete spectrum of information about these principles in a clear and accessible format. It serves as an ideal book for undergraduate/graduate students of Food Technology, Food Science and Nutrition.This book provides information on:· Major and minor food constituents, properties and food applications of carbohydrates, proteins & fats.· Different interactions in food systems and various changes in foods on storage and processing.· Nutritional functions of food and Recommended dietary allowances of nutrients.Digestion, absorption, transport and metabolism of nutrients.
