This book presents the principles and practices of rock blasting for underground hard rock mining. It covers a theoretical background of the rock blasting technology and comprehensive case studies on different stages of rock blasting for underground metalliferous mining. It includes the discussions on burn-cut face blasting pattern, slot raise excavation methodology, and ring blasting methods. It further discusses different practical challenges associated with underground blasting, viz. ore dilution, ground vibration, wall instability, etc., and their possible solutions. The book also covers the recent advancements in methodologies to predict blasting outcomes and instrumentations for monitoring rock blasting operations. The book is a useful reference for rock blasting practitioners, mining engineers, professionals, and researchers. It is also a valuable reference for undergraduate and postgraduate students.
Institutions are norms that undergird organizations and are reflected in laws and practices. Over time, institutions take root and persist as they are path dependent and thus change resistant. Therefore, it is puzzling when institutions change. One such puzzle has been the enactment of the Right to Information (RTI) Act in India in 2005, which brought about institutional change by transforming the 'information regime'. Why did the government upend the norm of secrecy, which had historically been entrenched within the Indian State? This book uses archival material, internal government documents, and interviews to understand the why and how of institutional change. It demonstrates that the institutional change resulted from 'ideas' emerging gradually and incrementally, leading to a 'tipping point'. About the IDSA Series: This series interrogates the interplay between globalization, the state, and social forces in the making and un-making of institutions in South Asia. Why do institutions persist and change? Do we need to transcend materialism and dwell in ideas and culture as well to understand why institutions perform and fail? The first book in the Institutions and Development in South Asia series, this volume studies the historical institutionalism in the information regime in India by presenting an alternative narrative about the evolution of the RTI Act.
His jaw lies here, but he is no more. He was not his bones turned to ash. He was not his flesh melted away.' At the first step of a promising career, Ranchor returns home to face the sobering reality of his father's demise. A railway employee prevents a young man's desperate attempt at suicide. Elsewhere, a doctor faces the harrowing prospect of facilitating euthanasia for a friend. In an idyllic city, Keshav's life is slowly engulfed by a terminal illness, and the spectre of death looms large. Written in searing prose, these stories by debut author Himanshu Asnani are a rich portrait of lives that mirror countless others. Probing and often edifying, they capture the pathos of life while offering succour to those traversing similar paths - a reminder of fiction's singular ability to lay bare life's fundamental questions.
No matter who you are, where you live, or what your life circumstances are, if you’ve gone through the teenage, you must remember the first time you’ve fallen in love. The time when you’ve created your own universe in your mind. The time when you used to fly high and high in your dreams. The time when you used to get butterflies in your stomach. The time when only a smile can melt your heart and a whiff can cure all your pains. But then we grew up and something is left behind, some words, some feelings, some emotions. Something that is left unspoken, the words that left unexpressed. People do move on in life but something remains there for always. Some of them just feel those vibes and some of them make those moments immortal by penning down their heart in form of poetries, writings and shayaris, in their diaries. The book is all about those feelings that are left unexpressed, some words that are left unspoken. Let’s take this moment to celebrate the journey of our lives, and dive into some stories penned down by some awesome co-authors.

The book: Provides comprehensive review of the prediction methodologies of blasting results. Reviews insights into advanced blasting methodologies for rock excavation near sensitive structures. Includes case studies of coal mining, iron ore mining, limestone mining and civil construction projects. Explores the detailed theoretical background of rock blasting. Discusses methodologies of secondary blasting. This book is aimed at graduate students and researchers in mining, geotechnical, and rock engineering.
Prior to European expansion, communities of the Indian subcontinent had a strong maritime orientation. In this new archaeological study, Himanshu Prabha Ray explores seafaring activity, religious travel and political economy in this ancient period. By using archaeological data from the Red Sea to the Indonesian archipelago, she reveals how the early history of peninsular South Asia is interconnected with that of its Asian and Mediterranean partners in the Indian Ocean Region. The book departs from traditional studies, focusing on the communities maritime history rather than agrarian expansion and the emergence of the state. Rather than being a prime mover in social, economic and religious change, the state is viewed as just one participant in a complex interplay of social actors, including merchants, guilds, boat-builders, sailors, pilgrims, religious clergy and craft-producers. A study that will be welcomed by students of Archaeology and Ancient History, particularly those interested in South Asian Studies.
This book has evolved from the passionate desire of the authors in using the modern concepts of multibody dynamics for the design improvement of the machineries used in the rural sectors of India and The World. In this connection, the first author took up his doctoral research in 2003 whose findings have resulted in this book. It is expected that such developments will lead to a new research direction MuDRA, an acronym given by the authors to “Multibody Dynamics for Rural Applications. ” The way Mu- DRA is pronounced it means ‘money’ in many Indian languages. It is hoped that practicing MuDRA will save or generate money for the rural people either by saving energy consumption of their machines or making their products cheaper to manufacture, hence, generating more money for their livelihood. In this book, the initial focus was to improve the dynamic behavior of carpet scrapping machines used to wash newly woven hand-knotted c- pets of India. However, the concepts and methodologies presented in the book are equally applicable to non-rural machineries, be they robots or - tomobiles or something else. The dynamic modeling used in this book to compute the inertia-induced and constraint forces for the carpet scrapping machine is based on the concept of the decoupled natural orthogonal c- plement (DeNOC) matrices. The concept is originally proposed by the second author for the dynamics modeling and simulation of serial and - rallel-type multibody systems, e. g.
