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.

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."
