Parachute Recovery Systems


Book Description

The purpose of this manual is to provide recovery system engineers in government and industry with tools to evaluate, analyze, select, and design parachute recovery systems. These systems range from simple, one-parachute assemblies to multiple-parachute systems, and may include equipment for impact attenuation, flotation, location, retrieval, and disposition. All system aspects are discussed, including the need for parachute recovery, the selection of the most suitable recovery system concept, concept analysis, parachute performance, force and stress analysis, material selection, parachute assembly and component design, and manufacturing. Experienced recovery system engineers will find this publication useful as a technical reference book; recent college graduates will find it useful as a textbook for learning about parachutes and parachute recovery systems; and technicians with extensive practical experience will find it useful as an engineering textbook that includes a chapter on parachute- related aerodynamics. In this manual, emphasis is placed on aiding government employees in evaluating and supervising the design and application of parachute systems. The parachute recovery system uses aerodynamic drag to decelerate people and equipment moving in air from a higher velocity to a lower velocity and to a safe landing. This lower velocity is known as rate of descent, landing velocity, or impact velocity, and is determined by the following requirements: (1) landing personnel uninjured and ready for action, (2) landing equipment and air vehicles undamaged and ready for use or refurbishment, and (3) impacting ordnance at a preselected angle and velocity.




Magnetic Properties of Rare Earth Metals


Book Description

The rare earths have a unique place among the elements. Although very much alike chemically and in most phy~ical properties they each have very different and striking magnetic properties. The reason, of course, lies in their 4f electrons which determine the magnetic properties but have little effect on other chemical and physical behaviour. Although they are not rare, some indeed are among the more common heavy elements in the earth's crust, the difficulty of separation has meant that their intricate magnetic properties have only recently been unravelled. Now, however, the general pattern of their magnetism is well charted and the underlying theory is well understood. Both are thoroughly summarised in this book. It provides an excellent example of the kind of extensive synthesis which is possible with modem solid state physics. it represents only a high plateau in the ascent to complete understanding. But It will become clear to the reader that while the overall position is satisfactory there are many details still to be elucidated experimentally and much to be done theoretically before all the underlying forces are identified and estimated from a priori calculations. It is hoped that the book will provide a useful stimulus in this direction. It should also be of use to those who are interested in related disciplines, for example the rare earth compounds, or the transition metals. In addition rare earths promise to be important technologically as alloy constituents.




Forensic Ethics and the Expert Witness


Book Description

This book details possible ethical situations and pitfalls that forensic psychiatric experts would commonly encounter when making a court testimony. Richly illustrated with cases from medicine, psychiatry, and law, this elegantly written volume examines the common moral ground that links these usually separate domains, and relates forensic ethics to larger concepts of morality and justice.




Planetary Geology


Book Description

Recent planetary missions by NASA, the European Space Agency, and other national agencies have reaffirmed that the geological processes which are familiar from our studies of Earth also operate on many solid planets and satellites. Common threads link the internal structure, thermal evolution, and surface character of both rocky and icy worlds. Volcanoes, impact craters, ice caps, dunes, rift valleys, rivers, and oceans are features of extra-terrestrial worlds as diverse as Mercury and Titan. The new data reveal that many of the supposedly inert planetary bodies were recently subject to earthquakes, landslides, and climate change and that some of them display active volcanism. Moreover, our understanding of the very origins of the solar system depends heavily on the composition of meteorites from Mars reaching the Earth and of rock fragments found on the Moon. Planetary Geology provides the student reader and enthusiastic amateur with comprehensive coverage of the solar system viewed through the eyes of Earth scientists. Combining extensive use of imagery, the results of laboratory experiments, and theoretical modeling, this comprehensively updated second edition (previously published in paperback and now available in hardback) presents fresh evidence that, to quote the first edition, planetary geology now embraces conventional geology and vice versa. *** " . . . a much improved version of what was already a good book. The new text is some 20 percent longer . . . color illustrations have been dispersed throughout . . . and the information presented is brought right up to the minute with numerous injections of new scientific results from the many space missions that have been conducted since the first edition appeared. Recommended." - Choice, Vol. 51, No. 07, March 2014~




The Domestic Terrorist Threat


Book Description

The emphasis of counterterrorism policy in the United States since Al Qaeda's attacks of September 11, 2001 (9/11) has been on jihadist terrorism. However, in the last decade, domestic terrorists-people who commit crimes within the homeland and draw inspiration from U.S.-based extremist ideologies and movements-have killed American citizens and damaged property across the country. Not all of these criminals have been prosecuted under terrorism statutes. This latter point is not meant to imply that domestic terrorists should be taken any less seriously than other terrorists.




The Stalin Era


Book Description

This book provides a wide-ranging history of every aspect of Stalin's dictatorship over the peoples of the Soviet Union. Drawing upon a huge array of primary and secondary sources, The Stalin Era is a first-hand account of Stalinist thought, policy and and their effects. It places the man and his ideology into context both within pre-Revolutionary Russia, Lenin's Soviet Union and post-Stalinist Russia. The Stalin Era examines: * collectivisation * industrialisation * terror * government * the Cult of Stalin * education and Science * family * religion: The Russian Orthodox Church * art and the state.

Telepresence & Bio Art


Book Description

"Eduardo Kac's work represents a turning point. What it questions is our current attitudes to creativity, taking that word in its most fundamental sense." -Edward Lucie-Smith, author of Visual Arts in the 20th Century "His works introduce a vital new meaning into what had been known as the creative process while at the same time investing the notion of the artist-inventor with an original social and ethical responsibility." -Frank Popper, author of Origins and Development of Kinetic Art "Kac's radical approach to the creation and presentation of the body as a wet host for artificial memory and 'site-specific' work raises a variety of important questions that range from the status of memory in digital culture to the ethical dilemmas we are facing in the age of bioengineering and tracking technology." -Christiane Paul, Whitney Museum of Art For nearly two decades Eduardo Kac has been at the cutting edge of media art, first inventing early online artworks for the web and continuously developing new art forms that involve telecommunications and robotics as a new platform for art. Interest in telepresence, also known as telerobotics, exploded in the 1990s, and remains an important development in media art. Since that time, Kac has increasingly moved into the fields of biology and biotechnology. Telepresence and Bio Art is the first book to document the evolution of bio art and the aesthetic development of Kac, the creator of the "artist's gene" as well as the controversial glow-in-the-dark, genetically engineered rabbit Alba. Kac covers a broad range of topics within media art, including telecommunications media, interactive systems and the Internet, telematics and robotics, and the contact between electronic art and biotechnology. Addressing emerging and complex topics, this book will be essential reading for anyone interested in contemporary art.







Spoken Libyan Arabic


Book Description

The aim of this book (with a cassette tape or a Audio CD*) is to aid the student possessing a background in Modern Standard Arabic to comprehend the spoken Libyan dialect, or, more precisely, the two main urban dialects, that of Tripoli in the west and Benghazi in the East. The two speakers in the dialogues are from Tripoli and from the countryside surrounding Benghazi. A special aspect of the thirty selections in the book is that they are the spontaneous speech of ordinary informants and that they have been edited on for the sake of length. The selections are transcribed into a modified version of the International Phonetic Alphabet. Selections are accompanied by a vocabulary and notes, and there is a global glossary at the end of the book. An English tranlation of each selection is also provided. 3 audio CDs included.
