Introducing the first, self-contained reference on acoustic waveform logging Acoustic measurements in boreholes were first made as a specialized logging technique in geological exploration, but recent advances have greatly expanded the potential applications of this technique. Acoustic Waves in Boreholes provides a thorough review of the theory and interpretation techniques needed to realize these applications, emphasizing the role of guided modes and critically refracted waves in determining the characteristics of recorded waveforms. Topics covered in this comprehensive volume include the seismic properties of rocks; propagation of axisymmetric waves along fluid-filled boreholes in isotropic rocks; and symmetric and nonsymmetric sources in isotropic, transversely isotropic, and porous, permeable formations in open and cased boreholes. Each chapter includes the theory of synthetic microseismogram computation, interpretation and data inversion techniques illustrated using computed seismograms, and case histories using experimental data. Appendices providing the mathematical formulation needed to compute microseismograms, with a single consistent notation used throughout, are also included in appropriate chapters. The wide range of geomechanical properties covered in this book will interest exploration geophysicists, reservoir engineers, civil engineers, geologists, and soil scientists.

This important new book focuses on the involvement of cytokines in specific areas of inflammatory diseases, such as granulomatous responses, lung disease, hepatic dysfunction and the acute phase, arthritis and accompanying bone remodeling, neurogenic inflammation, and shock. The roles of GM-CSF, IL-6, IL-2, TGFb EGF, and LIF are discussed, as well as the medical treatments that affect cytokine activity. The results of approaches important to the biotechnology and pharmaceutical industries, such as the search for endogenous biological response modifiers that control cytokine function or production, attempts to synthesize heterocyclic compounds in the organic chemistry lab, and research regarding second messenger pathways involved in IL-1 and TNF production are examined. This book will provide anyone in cytokine research, especially clinical investigators, pharmaceutical industry researchers, and academic research scientists, with important information on how cytokine research might be used.

Living on the Edge: Texas During the Civil War and Reconstruction explores the complex issues faced by Texans in the Civil War era. Through a wide range of primary source documents, the book sheds light on a distinct historical perspective born of the combination of geographic location and cultural diversity. The readings and primary source documents in the book record both exceptional and mundane events of everyday life during a dramatic and fascinating era. While students may already be familiar with slavery, secession, the war years, and the Reconstruction period, they will gain new insight into history through personal writings such as slave narratives and diaries. In addition, speeches and ads, government reports, and political documents reflect the perspective and concerns of society at the time. The geographic position of Texas combined with its cultural diversity make the history of Texas in the Civil War era unique. Living on the Edge: Texas During the Civil War and Reconstruction offers a look at an aspect of American history that is suitable for courses in Civil War history, Texas history, and historical methods.

Grand Admiral Alfred von Tirpitz (1849 1930) was the principal force behind the rise of the German Imperial Navy prior to World War I, challenging Great Britain s command of the seas. As State Secretary of the Imperial Naval Office from 1897 to 1916, Tirpitz wielded great power and influence over the national agenda during that crucial period. By the time he had risen to high office, Tirpitz was well equipped to use his position as a platform from which to dominate German defense policy. Though he was cool to the potential of the U-boat, he enthusiastically supported a torpedo boat branch of the navy and began an ambitious building program for battleships and battle cruisers. Based on exhaustive archival research, including new material from family papers, Tirpitz and the Imperial German Navy is the first extended study in English of this germinal figure in the growth of the modern navy."

For tens of thousands of Union veterans, Patrick Kelly argues, the Civil War never ended. Many Federal soldiers returned to civilian life battling the lifelong effects of combat wounds or wartime disease. Looking to the federal government for shelter and medical assistance, war-disabled Union veterans found help at the National Home for Disabled Volunteer Soldiers. Established by Congress only weeks prior to the Confederate surrender, this network of federal institutions had assisted nearly 100,000 Union veterans by 1900. The National Home is the direct forebear of the Veterans Administration hospital system, today the largest provider of health care in the United States.

Kelly places the origins of the National Home within the political culture of U.S. state formation. Creating a National Home examines Congress's decision to build a federal network of soldiers' homes. Kelly explores the efforts of the Home's managers to glean support for this institution by drawing upon the reassuring language of domesticity and "home." He also describes the manner in which the creators of the National Homes used building design, landscaping, and tourism to integrate each branch into the cultural and economic life of surrounding communities, and to promote a positive image of the U.S. state.

Drawing upon several fields of American history--political, cultural, welfare, gender--"Creating a National Home" illustrates the lasting impact of war on U.S. state and society. The building of the National Home marks the permanent expansion of social benefits offered to citizen-veterans. The creation of the National Home at once defined an entitled group and prepared the way for the later expansion ofboth the welfare and the warfare states.
