This volume contains the Proceedings of the Sixth International Symposium on Acoustical Holography and Imaging, held in San Diego, California, February 4-7, 1975. The title of this symposium differs from that of the first four by the addition of the word "Imaging," reflecting an increase in emphasis on nonholographic methods of acoustical visualization. For convenience, no change has been made in the title of this published series. The 38 papers presented here define the state-of-the-art in the rapidly developing field of acoustical holography and imaging. Many of them describe applications in such fields as medical diagnostics, microscopy, nondestructive testing, underwater viewing, and seismology. The Editor recognizes the diligent efforts of the authors in advancing the technology of Acoustical Imaging and thanks them for preparing and submitting descriptions of their work. The papers were selected with the able assistance of the Program Committee that con sisted of P.S. Green, Stanford Research Institute; J.F. Havlice, Stanford Microwave Laboratory; B.P. Hildebrand, Battelle Northwest; D.R. Holbrooke, Children's Hospital of San Francisco; P.N. Keating, Bendix Research Laboratories; A. Korpel, Zenith Radio Corporation; B.J.

One of the foremost objectives of landscape architectural design is to impart an organizational order in the landscape. Heavily illustrated, this enlightening book introduces the basic elements and principles of design, and then explores the spatial language used to organize and shape landscape architectural design. With more than five hundred hand-rendered graphics and over 150 photographs, this book offers students, professionals and life-long learners a complete introduction to the visual language that is the underpinning of landscape architectural design.

Although Turkey still depends on the United States and other NATO allies for political and strategic support, growing economic diversification and military self-reliance allows Turkey to exercise greater leverage with the West. These trends have helped fuel continuing Turkish political transformation led in the past decade by Prime Minister Recep Tayyip Erdogan and the Justice and Development Party (AKP), which has Islamist roots. Future domestic political developments may determine how Turkey reconciles respect for democratic views that favour Turkish nationalism and traditional Sunni Muslim values with protection of individual freedoms, minority rights, rule of law, and the principle of secular governance. This book examines U.S. relations with Turkey, with a focus on domestic and foreign policy issues; the decline in Israel-Turkey relations; and ongoing change in the Middle East region.
