Turbulent reactive flows are of common occurrance in combustion engineering, chemical reactor technology and various types of engines producing power and thrust utilizing chemical and nuclear fuels. Pollutant formation and dispersion in the atmospheric environment and in rivers, lakes and ocean also involve interactions between turbulence, chemical reactivity and heat and mass transfer processes. Considerable advances have occurred over the past twenty years in the understanding, analysis, measurement, prediction and control of turbulent reactive flows. Two main contributors to such advances are improvements in instrumentation and spectacular growth in computation: hardware, sciences and skills and data processing software, each leading to developments in others. Turbulence presents several features that are situation-specific. Both for that reason and a number of others, it is yet difficult to visualize a so-called solution of the turbulence problem or even a generalized approach to the problem. It appears that recognition of patterns and structures in turbulent flow and their study based on considerations of stability, interactions, chaos and fractal character may be opening up an avenue of research that may be leading to a generalized approach to classification and analysis and, possibly, prediction of specific processes in the flowfield. Predictions for engineering use, on the other hand, can be foreseen for sometime to come to depend upon modeling of selected features of turbulence at various levels of sophistication dictated by perceived need and available capability.

In 1989, South Africa made the momentous decision to abandon its nuclear weapons, making it the first and still the only country that has produced nuclear weapons and given them up. Over thirty years, the apartheid regime had created a remarkably sophisticated capability to build nuclear weapons-both the nuclear warhead and advanced military systems to deliver them. The program was born in secret and remained so until its end. The government initially sought to dismantle it in secret. It hoped to avoid any negative international consequences of possessing nuclear weapons. The apartheid government's strategy did not work, because too many intelligence agencies knew about South Africa's nuclear weapons. Faced with intense pressure, South Africa's President F.W. de Klerk reversed course and adopted a policy of transparency in 1993. However, he decided to hide many of its aspects. Nonetheless, most of the remaining secrets emerged over the ensuing 25 years. Revisiting South Africa's Nuclear Weapons Program draws on previously secret information to provide the first comprehensive, technically-oriented look at South Africa's nuclear weapons program; how it grew, evolved, and ended. It also finds lessons for today's nuclear proliferation cases.

Most materials and crystals have an atomic structure which is described by a regular stacking of a microscopic fundamental unit, the unit cell. However, there are also many well ordered materials without such a unit cell. This book deals with the structure determination and a discussion of the main special properties of these materials.

This book presents the foundations of the theory of groups and semigroups acting isometrically on Gromov hyperbolic metric spaces. Particular emphasis is paid to the geometry of their limit sets and on behavior not found in the proper setting. The authors provide a number of examples of groups which exhibit a wide range of phenomena not to be found in the finite-dimensional theory. The book contains both introductory material to help beginners as well as new research results, and closes with a list of attractive unsolved problems.
