Ashok Gupta

This book is a stunning wise philosophical look of the eastern author at extraordinary activities and global mission of Vladimir Putin - the President of Russia. Bangladeshi writer and social leader with Indian roots Dr. Ashok Gupta has his own point to say about this great leader. Dr. Ashok Gupta lived many years in USSR and Russia and would like to familiarise the readers around the world with the truth about Vladimir Putin. This book still has not been distributed or supported by officials in Russia. The author impartially and concisely sets out the chronology of events from the life of the President of Russia. At the same time, he could easily and convincingly refute the foisted mass media clich s about Vladimir Putin. The text of this book takes the reader through the historical events with a logical conclusion regarding the mission of Vladimir Putin in the development of modern humanity and the whole planet...

Mineral Processing Design and Operations: An Introduction, Second Edition, helps further understanding of the various methods commonly used in mineral beneficiation and concentration processes. Application of theory to practice is explained at each stage, helping operators understand associated implications in each unit process. Covers the theory and formulae for unit capacities and power requirements to help the designer develop the necessary equipment and flow-sheets to economically attain maximum yield and grade. This second edition describes theories and practices of design and operation of apparatus and equipment, including an additional chapter on magnetic, electrostatic, and conductivity modes of mineral separation. Basics of process controls for efficient and economic modes of separation are introduced.

and Literature Rev iew Chapter 1 1. INTRODUCTION AND LITERATURE REVIEW The exploration for oil and gas in ever increasing water depths has given an impetus to research efforts on the behaviour of offshore structures under ocean environment. These structures are continuously subjected to environmental loading because of waves, wind and current. A response analysis is required to assess the safety of offshore structure under severe storm conditions as well as for estimation of damage caused by less severe but more frequently occuring sea states. A majority of the reported failures in the life time of offshore structures are in fact fatigue failures. The offshore structures are usually built in the form of welded tubular structures. The joints of these tubular members experience the fatigue damage mainly due to small defects in welding which act as crack initiators, high stress concentrations and the variable loads. The variable loads due to the ocean waves cause cyclic stress variation in the structural members and the accumu­ lated effect of these stresses results in the fatigue failure.
