Book Description
Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.

Book Description
In a world where advanced knowledge is widespread and low-cost labor is readily available, U.S. advantages in the marketplace and in science and technology have begun to erode. A comprehensive and coordinated federal effort is urgently needed to bolster U.S. competitiveness and pre-eminence in these areas. This congressionally requested report by a pre-eminent committee makes four recommendations along with 20 implementation actions that federal policy-makers should take to create high-quality jobs and focus new science and technology efforts on meeting the nation's needs, especially in the area of clean, affordable energy: 1) Increase America's talent pool by vastly improving K-12 mathematics and science education; 2) Sustain and strengthen the nation's commitment to long-term basic research; 3) Develop, recruit, and retain top students, scientists, and engineers from both the U.S. and abroad; and 4) Ensure that the United States is the premier place in the world for innovation. Some actions will involve changing existing laws, while others will require financial support that would come from reallocating existing budgets or increasing them. Rising Above the Gathering Storm will be of great interest to federal and state government agencies, educators and schools, public decision makers, research sponsors, regulatory analysts, and scholars.

Book Description
This book gathers the latest advances, innovations, and applications in the field of innovative biosystems engineering for sustainable agriculture, forestry and food production. Focusing on the challenges of implementing sustainability in various contexts in the fields of biosystems engineering, it shows how the research has addressed the sustainable use of renewable and non-renewable resources. It also presents possible solutions to help achieve sustainable production. The Mid-Term Conference of the Italian Association of Agricultural Engineering (AIIA) is part of a series of conferences, seminars and meetings that the AIIA organizes, together with other public and private stakeholders, to promote the creation and dissemination of new knowledge in the sector. The contributions included in the book were selected by means of a rigorous peer-review process, and offer an extensive and multidisciplinary overview of interesting solutions in the field of innovative biosystems engineering for sustainable agriculture.

Book Description
As a leading reference on pediatric cardiology and congenital heart disease, Anderson's Pediatric Cardiology provides exhaustive coverage of potential pediatric cardiovascular anomalies, potential sequelae related to these anomalies, comorbidities and neurodevelopmental problems, and current methods for management and treatment. The fully revised 4th Edition addresses significant and ongoing changes in practice, including recent developments in fetal, neonatal, and adult congenital heart conditions as well as expanded content on intensive care, nursing issues, and societal implications. The outstanding illustration program provides superb visual guidance, and is now supplemented with a remarkable collection of more than 200 professionally curated, author-narrated videos. - Offers authoritative, long-term coverage of a broad spectrum of cardiology conditions, including congenital heart disease, adult congenital heart disease (ACHD), acquired heart disease, cardiomyopathies, and rhythm disturbances. - Features exquisite specimen images by Dr. Robert Anderson and Diane Spicer dissected in easily recognizable analogous imaging planes. These are included in the over 850 anatomic, photographic, imaging, and algorithmic figures, and incorporate new images using virtual dissections of 3D datasets obtained in living patients. - An extensive new section describing the non-cardiac consequences of congenital cardiac disease and other related issues Outside the Heart, including new chapters on quality improvement in congenital cardiac disease, models of care delivery, neurocognitive assessment and outcomes, psychosocial issues for patients and families, ethics, nursing implications, acute and chronic renal complications, and telemedicine. - Three entirely new, expanded sections on the Functionally Univentricular Heart, Fetal Congenital Cardiac Disease, and Heart Failure and Transplantation. - Provides a new focus on patient and family-centered care with expert advice on how to communicate difficult diagnoses to patients and families. - Features new integration of nursing content into all disease-specific chapters, as well as updated content on genetics, congenital heart disease and follow-up, and new imaging modalities. - Contains chapters on new and emerging topics such as MRI and Quantifying the Fetal Circulation in Congenital Cardiac Disease; Congenital Anomalies of the Coronary Arteries; and The Global Burden of Pediatric Heart Disease and Pediatric Cardiac Care in Low- and Middle-Income Countries - Shares the experience and knowledge of an international team of multidisciplinary experts in medicine and advanced practice nursing. - Expert ConsultTM eBook version included with purchase. This enhanced eBook experience allows you to search all of the text, tables and figures from the book on a variety of devices.

Book Description
In the last few years, a significant increase in applications of MMCs has taken place, particularly in the areas of automotive, aerospace, electronics, and recreation. These include continuous fiber reinforced MMCs for cables in power transmission, high temperature superconducting wires, particulate MMCs in civilian aircraft and automotive applications, and high volume fraction, high thermal conductivity substrates for electronic packaging. Nevertheless, as with any novel material systems, there is a lack of fundamental understanding on the part of practicing engineers and designers. This book would seek to address these issues, in a thorough and cohesive manner, as well as to provide students and scientists with a basic understanding of MMCs. This book will emphasize the synergistic relationships among processing, structure, and properties of metal matrix composites.

Book Description
Volumes in Writing Spaces: Readings on Writing offer multiple perspec- tives on a wide-range of topics about writing. In each chapter, authors present their unique views, insights, and strategies for writing by ad- dressing the undergraduate reader directly. Drawing on their own ex- periences, these teachers-as-writers invite students to join in the larger conversation about the craft of writing. Consequently, each essay func- tions as a standalone text that can easily complement other selected readings in writing or writing-intensive courses across the disciplines at any level.
