It is possible to "stretch" a liquid and, when suitably prepared, liquids are capable of sustaining substantial levels of tension, often for significant periods of time. These negative pressure states are metastable but can last for days - long enough for substantial experimental investigation. This volume is a review of recent and current research into the behaviour of liquids under negative pressure. Part I deals with the thermodynamics of stretched liquids. Part II discusses the physical and...

General ultrasound in the critically ill describes a new clinical tool: ultrasound for the intensive care and emergency physician. Written by an intensivist familiar with ultrasound, it specifically details findings of immediate clinical relevance throughout its approx. 220 pages. Through a whole-body approach, this book considers new emergency applications regarding the abdomen, venous system, head, heart, and the most original topic, the lung. Flow charts are proposed to resolve daily intensiv...

The ultrasonic motor, invented in 1980, utilizes the piezoelectric effect in the ultrasonic frequency range to provide the motive force. (In conventional electric motors the motive force is electromagnetic). The result is a motor with unusually good low-speed high-torque and power-to-weight characteristics. It has already found applications in camera autofocus mechanisms, medical equipment subject to high magnetic fields, and motorized car accessories. Its applications will increase as desig...

This volume of the new series, "Medical Radiology" addresses the important topic of "Innovations in Diagnostic Radiology". It presents examples of current work of interest not only to the radiological community but to physicians in other medical disciplines and to scientists in general. The impact of radiology on diagnostic medicine and patient management has been obvious from the beginning of our specialty. However, the evolution of the field is expanding at an astounding rate. During the profe...

Die Analyse und Synthese akustischer Spektren wird heute immer wichtiger in so verschiedenen Fachgebieten wie Sonar- und Radar-Technik, in der zerstoerungsfreien Materialprufung, in der medizinischen Ultraschall-Diagnose, in der Geophysik und in der Raumakustik des Ingenieurbaus. Der Autor liefert eine moderne Fourier-Spektrographie, deren zentrales Thema die Formung akustischer Spektren beinhaltet. Das Buch vermittelt die mathematischen und physikalischen Grundlagen und liefert Loesungsstrategi...

The International Symposium on Acoustical Imaging is a unique forum for advanced research, covering new technologies, developments, methods and theories in all areas of acoustics. This interdisciplinary Symposium has been taking place continuously since 1968. In the course of the years the proceedings volumes in the Acoustical Imaging Series have become a reference for cutting-edge research in the field. In 2011 the 31st International Symposium on Acoustical Imaging was held in Warsaw, Poland, A...

Ein grosser Teil der empfangenen Ultraschallinformation geht bei der Erstellung des Ultraschallbildes am Bildschirm verloren. Im vorliegenden Buch werden Techniken vorgestellt, die diese bislang nicht genutzten Informationen verwerten. Im Mittelpunkt stehen die Ultraschallhochfrequenzanalyse und die dreidimensionale Darstellung von Ultraschallbildern. Aber auch Anwendungen wie die Duplexsonographie und die Angiodynographie sowie die elektronische Befunddokumentation werden behandelt. Das Buch gi...

India is the second most populous nation in the world, but the dynamics of daily life are not understood by many in the West. This work examines various aspects of Indian families: how they are organized, how property is distributed in marriage, and the structure and change of the household. It develops each aspect with a discussion of regional differences and classic writings in the field. Clearly written, this work is helpful to all those interested in families, social alliances, and comparati...

The aim of this book is to teach the design and construction of micromachined ultrasonic transducers, an area rapidly increasing in popularity, and contrast and compare these transducers to each other and to traditional piezoelectric transducers. Micromachined ultrasonic transducers are gaining wide acceptance because of the use of silicon micromachining for their manufacture. This also enables capabilities of these transducers that outperform piezoelectric transducers and enable configurations...
