Book Description
Military and defense-related procurement has been an important source of technology development across a broad spectrum of industries that account for an important share of United States industrial production. In this book, the author focuses on six general-purpose technologies: interchangeable parts and mass production; military and commercial aircraft; nuclear energy and electric power; computers and semiconductors; the INTERNET; and the space industries. In each of these industries, technology development would have occurred more slowly, and in some case much more slowly or not at all, in the absence of military and defense-related procurement. The book addresses three questions that have significant implications for the future growth of the United States economy. One is whether changes in the structure of the United States economy and of the defense-industrial base preclude military and defense-related procurement from playing the role in the development of advanced technology in the future, comparable to the role it has played in the past. A second question is whether public support for commercially oriented research and development will become an important source of new general-purpose technologies. A third and more disturbing question is whether a major war, or the threat of major war, will be necessary to mobilize the scientific, technical, and financial resources necessary to induce the development of new general-purpose technologies. When the history of United States technology development in the next half century is written, it will focus on incremental rather than revolutionary changes in both military and commercial technology. It will also be written within the context of slower productivity growth than of the relatively high rates that prevailed in the United States in the 1950s and 1960s or during the information technology bubble that began in the early 1990s. These will impose severe constraints on the capacity of the United States to sustain a global-class military posture and a position of leadership in the global economy.

Book Description
The Thermohaline Finestructure of the Ocean is a five-chapter text that describes the fine-scale stratification phenomenon in the ocean and the physical processes that participate in its formation and govern its evolution. After an introduction to the concept of thermohaline finestructure of the ocean, this book goes on presenting some methodological aspects in connection with the finestructure measurements in the ocean. The next chapters examine the complex interrelations between the fine-scale stratification of the ocean water. The remaining chapters explore several important physical processes, such as molecular diffusion, convection, turbulence, internal gravity waves, inertial motions, and mean currents. This book is written for physical oceanographers and specialists in other related branches of research.

Book Description
A fugitive from federal justice, Lieutenant Max Ewing returns home to the Gulf port city of Apalachicola determined to seek revenge. The War Between the States has ended, but Apalachicola remains occupied by federal troops and local opportunists emboldened and empowered by the war. Max's brother Randy has died, a victim of shipboard hostilities in the Bay of Cardenas. Soon, Ewing learns of other losses incurred in his absence: his mother's death from yellow fever, the confiscation of his family's property, and the fates and deaths of many friends.Revenge, loyalty, honor, passion and greed clash in this dramatic tale, set among the raw and rugged elements of Florida's Gulf coast at a turbulent time in its history.

Book Description
This volume contains the proceedings of the 19th International Liège Colloquium on Ocean Hydrodynamics, the programme of which focused on the relationships between small-scale mixing and large-scale features, transports and processes. The presentation of papers on various methods of parameterization of small-scale turbulent mixing for numerical ocean models was particularly encouraged and this resulted in more than a third of the papers presented at the Colloquium dealing in one way or another with the parameterization problems; many of these papers demonstrate the direct results of modelling. These proportions are well reflected in this volume of proceedings and thus emphasize once more the importance of small-scale turbulence research for such vital practical applications as ocean modelling and forecasting.

Book Description
Spatial inhomogeneity of heating of fluids in the gravity field is the cause of all motions in nature: in the atmosphere and the oceans on Earth, in astrophysical and planetary objects. All natural objects rotate and convective motions in rotating fluids are of interest in many geophysical and astrophysical phenomena. In many industrial applications, too (crystal growth, semiconductor manufacturing), heating and rotation are the main mechanisms defining the structure and quality of the material. Depending on the geometry of the systems and the mutual orientation of temperature and gravity field, a variety of phenomena will arise in rotating fluids, such as regular and oscillating waves, intensive solitary vortices and regular vortex grids, interacting vortices and turbulent mixing. In this book the authors elucidate the physical essence of these phenomena, determining and classifying flow regimes in the space of similarity numbers. The theoretical and computational results are presented only when the results help to explain basic qualitative motion characteristics. The book will be of interest to researchers and graduate students in fluid mechanics, meteorology, oceanography and astrophysics, crystallography, heat and mass transfer.

Book Description
“Golway’s revisionist take is a useful reminder of the unmatched ingenuity of American politics.”—Wall Street Journal History casts Tammany Hall as shorthand for the worst of urban politics: graft and patronage personified by notoriously crooked characters. In his groundbreaking work Machine Made, journalist and historian Terry Golway dismantles these stereotypes, focusing on the many benefits of machine politics for marginalized immigrants. As thousands sought refuge from Ireland’s potato famine, the very question of who would be included under the protection of American democracy was at stake. Tammany’s transactional politics were at the heart of crucial social reforms—such as child labor laws, workers’ compensation, and minimum wages— and Golway demonstrates that American political history cannot be understood without Tammany’s profound contribution. Culminating in FDR’s New Deal, Machine Made reveals how Tammany Hall “changed the role of government—for the better to millions of disenfranchised recent American arrivals” (New York Observer).
