Найти книгу: "Physical Principles of Medical Ultrasonics"

The physical properties of ultrasound, particularly its highly directional beam behaviour, and its complex interactions with human tissues, have led to its becoming a vitally important tool in both investigative and interventional medicine, and one that still has much exciting potential. This new edition of a well-received book treats the phenomenon of ultrasound in the context of medical and biological applications, systematically discussing fundamental physical principles and concepts. Rather than focusing on earlier treatments, based largely on the simplifications of geometrical acoustics, this book examines concepts of wave acoustics, introducing them in the very first chapter. Practical implications of these concepts are explored, first the generation and nature of acoustic fields, and then their formal descriptions and measurement. Real tissues attenuate and scatter ultrasound in ways that have interesting relationships to their physical chemistry, and the book includes coverage of these topics. Physical Principles of Medical Ultrasonics also includes critical accounts and discussions of the wide variety of diagnostic and investigative applications of ultrasound that are now becoming available in medicine and biology. The book also encompasses the biophysics of ultrasound, its practical applications to therapeutic and surgical objectives, and its implications in questions of hazards to both patient and operator.

Rizzoni is designed for the sophomore/junior level, Introduction to Electrical Engineering course required for non-EE majors. The most widely used book for this course, Rizzoni introduces non-majors to the three basic areas of electrical engineering: circuits, electronics, and electromechanics. The second edition continues the tradition of focusing on the topics and issues of interest to the non-electrical engineering student. To maintain student interest in these topics, Rizzoni provides numerous links between electrical engineering and other engineering fields.

The book is a collection of papers presented at the conference «Russia and Norway: Physical and Symbolic Borders» held in St Petersburg in April 2005 in connection with the opening of the exhibition «Norway – Russia. Neighbours through the ages». In the book different aspects of the history of the Norwegian-Russian border are covered by historians from Moscow, St Petersburg, Arkhangelsk, Copenhagen, Cambridge, Bergen and Tromso. The papers are diverse and refer to different chronological periods. One group of articles deals with problems connected with the medieval border treaties between Norway and Novgorodian Russia, others with the diplomatic history of the border convention of 1826, as well as its effect on ethnic minorities living in the border area. One author addresses the present-day delimitation controversy between Norway and Russia in the Barents Sea. Other articles deal with symbolic borders, for example, barriers in translating Russian literature into Norwegian, and borders between the two cultures, experienced by the Russian emigrants in Norway after the Russian Revolution. And finally, there are articles without explicit references to the concept of borders, where the authors investigate in more general terms different aspects of Norwegian-Russian relations.
