The current state of the art of several aspects of minerals and petroleum is presented in this volume. It documents the proceedings of the Internationl symposium on Particle Technology and Surface Phenomena in Minerals and Petroleum sponsored by the Fine Particle Society (FPS). This meeting was held in San Diego, California, August 21-25, 1990. The symposium upon which this volume is based was organized in five sessions emphasizing various basic and applied aspects of research on minerals and petroleum technology. Major topics discussed involve surface phenomena in minerals, mineral flotation, characterization of aspaltenes, theoretical aspects of reservoir simulation, porosity, permeability, residual water saturation, hydrocarbon and gas potential in north slope Alaska, polymer/alkaline flooding, surfactant flooding and foam flooding for enhanced oil recovery. This edition includes eighteen selected papers presented in the symposium. These papers are divided in four broad categories: (1) Asphaltene Aggregation and Characterization, (2) Theoretical Aspects and Reservoir Characterization, (3) Colloidal Dispersions in Minerals/Petroleum, and (4) Surface Phenomena and Petroleum Recovery. Several mineral and oil recovery processes using various chemicals with special reference to surface phenomena and particle technology are described in these sections.

From a general point of view the importance of striving to minimize envir- mental disturbances on the continental shelf cannot be overemphasized. Coastal areas are sites of population centers, navigation and recreation activities, and - source development, all of which contribute to environmental stress on the shelf. Proper management of the shelf for optimum use requires a thorough understanding of shelf processes. Complex problems, such as the influence of hydrodynamics on sediment dispersal, element differentiation and migration, physiochemical changes at the sediment water interface, the relationship - tween the pollutants and sediments, and the type of substrate with regard to benthic community and/or man-made structures require a multidisciplinary approach to their solution. The present study interrelates meteorologic, hyd- graphic, sedimentologic, and geochemical parameters to derme specific envir- ments on the Alaskan Shelf. These observations are then related to geologic principles in an effort to elucidate the sedimentary processes and elemental migration on the shelf. Attempts have also been made to relate the sediment texture to the geochem- try of the sediments. Obviously the chemistry is complicated as a result of b- genic contributions and variable provenance; however, to some extent elemental differentiation accompanies textural differentiation in sediments. The distribution of elements in various phases of crustal (source) rocks is gen- ally interpreted on the basis of crystallographic concepts, especially the concept of isomorphism.

India is among the few countries with home made satellites in orbit. Indian Space programme while being impressive with arrays of achievements in peaceful use of the space has woefully lacked in dedicated military applications. Admittedly cartographic platforms in the orbit can be used by the military to meet their cartographic needs but, they fall short of the 10-15cm (4"-6") capabilities of the best military satellites today. In "Space Security from the Indian Perspective", the author examines the dimension of the space threat emanating from our adversaries and need to develop our own military capability in the space .He argues that reliance of space is not exclusive to defence alone in fact the dependence of civil sector is more critical. In defence, we need not only to develop affordable options but also take steps to safeguard our space assets to ensure their continued use. This book examines the ramification of the military space capability and the choices available to India to safeguard its space assets which would interest both the generalists and the specialists.

A number of books have been written on the 1946 Royal Indian Navy Mutiny but the true story of this historic event remains untold with few facts deliberately suppressed. The Inquiry Commission report gave graphic details of mutinous acts at all the naval stations but it awarded no punishment to the guilty. It glossed over the bad conditions of service leading to the mutiny. It recommended no action against naval administration although bad service conditions were stated to be the root cause of mutiny in the Navy. It was an irony of British Naval Justice that the men voicing these bad service conditions were punished under the Naval Discipline Act. This book attempts to bring out a concise version of the composition and administration of the Navy including its sudden expansion during the World War II. The author's long association with naval counter intelligence has helped him to discern some unknown facts of this mutiny which are reflected in this book. It gives the build up and administrative background of Royal Indian Navy and details of mutinous acts in all stations because of which India did not have to fight any more for its freedom. The book, therefore, appropriately bears the title of 'Untold Story-1946 Naval Mutiny, the last war of Independence.'

Today India and the U.S share a convergance of interests on many fronts. This has been mainly due to the rapid pace of changes in the Indo-Pacific region and the consequent shift in geo-political and geo-economic centre of gravity. This book traces the Indo -US defence relations from the past when their policies and other differences in world view became a mjor barrier in developing close military relationship to the present strategic partnership, this volume also gives out the challenges and way ahead to overcome them.
