A History of Army Aviation 1950-1962


Book Description

U.S. Army aviation expanded dramatically in both size and breadth of activities after its inception in 1942, but much of its post-World War II history, particularly after the establishment of the Air Force as an independent service by the national Security Act of 1947, has been relatively neglected. Despite a certain amount of jockeying for position by both services, particularly in the early years after their separation, the Army was able to carve out a clear transport and operational combat role for its own air arm. "A History of Army Aviation - 1950-1962" examines the development of the Army's air wing, especially for air support of ground troops, both in terms of organization and in relation to the ongoing friction with the Air Force. After describing the rapid expansion of purely Army air power after 1950 and the accompanying expansion of aviation training, the book delves into the reorganization of aviation activities within a Directorate of Army Aviation. It also provides a valuable account of the successful development of aircraft armament, perhaps the most significant advance of this period. In particular, intensive experimentation at the Army Aviation School led to several practical weapons systems and helped to prove that weapons could be fired from rotary aircraft. This arming of the helicopter was to have a profound effect on both Army organization and combat doctrine, culminating in official approval of the armed helicopter by the Department of the Army in 1960. "A History of Army Aviation - 1950-1962" also explores the development of new aircraft between 1955 and 1962, including the UH-1 medical evacuation, transport, and gunship helicopter and the HC-1 cargo copter. In addition, the book discusses the Berlin Crisis of 1961 as an impetus for immediate and unexpected expansion of army aviation, quickly followed by the beginnings of intervention in Vietnam by the end of 1962.




Enhancing the Resilience of the Nation's Electricity System


Book Description

Americans' safety, productivity, comfort, and convenience depend on the reliable supply of electric power. The electric power system is a complex "cyber-physical" system composed of a network of millions of components spread out across the continent. These components are owned, operated, and regulated by thousands of different entities. Power system operators work hard to assure safe and reliable service, but large outages occasionally happen. Given the nature of the system, there is simply no way that outages can be completely avoided, no matter how much time and money is devoted to such an effort. The system's reliability and resilience can be improved but never made perfect. Thus, system owners, operators, and regulators must prioritize their investments based on potential benefits. Enhancing the Resilience of the Nation's Electricity System focuses on identifying, developing, and implementing strategies to increase the power system's resilience in the face of events that can cause large-area, long-duration outages: blackouts that extend over multiple service areas and last several days or longer. Resilience is not just about lessening the likelihood that these outages will occur. It is also about limiting the scope and impact of outages when they do occur, restoring power rapidly afterwards, and learning from these experiences to better deal with events in the future.

Rapid Recovery in Total Joint Arthroplasty


Book Description

The approach to total hip and total knee arthroplasty is changing around the world. There is now a strong emphasis on a more rapid recovery and on more outpatient surgery. Each step of the process is now being modified with more thorough pre-operative evaluations, streamlined surgical approaches, rapid mobilization and faster return to normal activities. These changes place new pressures on all of the health care providers in the system. This unique text - the first of its kind - is a practical guide for each member of the clinical team with updates by the leading authorities from around the country. Each chapter addresses a specific issue and will outline the important new items that need to be addressed, very similar to a handbook. Topics covered include the implementation of new payment models and outcome measurements, recommendations to streamline the pre-, peri- and post-operative protocols, the utility and application of outpatient joint replacement programs, multimodal pain management and post-acute rehabilitation strategies. There is no publication at present that addresses all of these items together in one convenient place. Rapid Recovery in Total Joint Arthroplasty is written and edited by experienced clinicians and surgeons, sharing their years of experience to create a practical, up-to-date text useful for everyday work.
