Music doesn t stop at the border, and neither should your textbook. This text gives students a global sense of music and its significance across cultures by introducing them to a diverse repertoire and developing listening skills applicable to all music. An accessible three-part model for listening sound, setting, and significance facilitates comparisons of various musical styles and meanings, and with Total Access, Soundscapes provides the digital resources students need to discover new music in a digitally connected world."
One of the first applications of ultrasound was in submarine sonar equip- ment. Since then ultrasound has found increasing applications, particularly in industry, but increasingly in biomedicine. For many years ultrasound has been used in physical therapy, although only in the past decade or two has it evolved from laboratory curiosity to a well-established diagnostic imaging modality. Ultrasound is now a widely accepted, indeed pervasive, diagnos- tic and therapeutic tool in the medical field, and its applications are increasing rapidly. Our intent in developing this book is to provide a coherent tutorial intro- duction to the field of medical ultrasound at a level suitable for those en- tering the area from either medical or scientific backgrounds. The topics discussed should be of interest to nearly all medical and health care per- sonnel needing to understand or operate ultrasonic devices, including clini- cians, medical technicians, physiotherapists, medical physicists, and other biomedical scientists interested in the field. The book opens with a description of the basic principles of propagating acoustic waves, explains how they interact with a wide range of biological systems, and outlines the effects they produce. To provide practical infor- mation to operators of ultrasound equipment, we have included thorough coverage of the details of ultrasonic instrumentation and measurement techniques, and set forth the framework for an effective quality assurance program.
Essay from the year 2010 in the subject Transportation Science & Technology, Seattle Pacific University, language: English, abstract: Ferries have played a crucial role in transportation around the Puget Sound, centered on the Seattle metropolis, since the first settlers arrived in the region. The natural water locked geography of the region necessitates such means of transportation. Ferries have evolved throughout the decades, and to the surprise of some, continue to serve an integral, irreplaceable role in the transportation structure of the city of Seattle. They have grown from canoes capable of transporting 30-100 people to massive "superferries" that today can carry thousands of passengers across the Sound in relative comfort and speed. This section will chronicle the development of the ferry system as an integral part of transportation and a key component of the infrastructure of the Puget Sound region from their conception until present.
