This is the only book on the market that has been conceived and deliberately written as a one-semester text on basic electric circuit theory. As such, this book employs a novel approach to the exposition of the material in which phasors and ac steady-state analysis are introduced at the beginning. This allows one to use phasors in the discussion of transients excited by ac sources, which makes the presentation of transients more comprehensive and meaningful. Furthermore, the machinery of phasors paves the road to the introduction of transfer functions, which are then used in the analysis of transients and the discussion of Bode plots and filters. Another salient feature of the text is the consolidation into one chapter of the material concerned with dependent sources and operational amplifiers. Dependent sources are introduced as linear models for transistors on the basis of small signal analysis. In the text, PSpice simulations are prominently featured to reinforce the basic material and understanding of circuit analysis.

As a species, we are currently experiencing dramatic shifts in our lifestyle, family structure, health, and global contact. Evolutionary Anthropology provides a powerful theoretical framework to study such changes, revealing how current environments and legacies of past selection shape human diversity. This book is the first major review of the emerging field of Applied Evolutionary Anthropology bringing together the work of an international group of evolutionary scientists, addressing many of the major public health and social issues of this century. Through a series of case studies that span both rural and urban situations in Africa, Asia, Europe and South America, each chapter addresses topics such as natural resource management, health service delivery, population growth and the emergence of new family structures, dietary, and co-operative behaviours. The research presented identifies the great, largely untapped, potential that Applied Evolutionary Anthropology holds to guide the design, implementation and evaluation of effective social and public health policy. This book will be of interest to policy-makers and applied researchers, along with academics and students across the biological and social sciences.

General relativity or the general theory of relativity is the geometric theory of gravitation published by Albert Einstein in 1915. It is the current description of gravitation in modern physics. General relativity generalises special relativity and Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime. In particular, the curvature of spacetime is directly related to the four-momentum (mass-energy and linear momentum) of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of partial differential equations. Einstein's theory has important astrophysical implications. For example, it implies the existence of black holes-regions of space in which space and time are distorted in such a way that nothing, not even light, can escape-as an end-state for massive stars. There is evidence that such stellar black holes as well as more massive varieties of black hole are responsible for the intense radiation emitted by certain types of astronomical objects such as active galactic nuclei or microquasars.

One would rarely have the opportunity to augment his medical library with a more exhaustive examination of the subject matter than is contained herein. Would only that all areas of one's professional responsibilities be available in such a complete, didactic, written form. Having a decided interest in the subject of head and neck paragangliomas for the past decade, I have had the opportunity to explore the subject through published medical literature and personal investi gation, and feel qualified to commend Doctors Zak and Lawson on their dedica tion, accuracy, and thoroughness in this presentation. One seeking any particular aspect of knowledge from historical to an up-to-date concept on the subject of paragangliomas will find his answer here. Vincent J. Hyams CAPT MC USN Chairman, Otolaryngic Pathology Department Armed Forces Institute of Pathology Washington, D.C. Preface One of us (F.G.Z.) initially became interested in the paraganglionic system when as a resident in pathology at The Mount Sinai Hospital, he performed an autopsy on an elderly woman with an intracranial tumor of the posterior fossa, which extended through the jugular foramen into the neck in a dumbbell fashion."

AMERICA STRIKES BACK
After Pearl Harbor, America seemed to have lost the war before it had begun. Allied forces were being beaten across the Pacific by the Japanese military juggernaut, and morale was at the breaking point. America desperately needed to strike back at the enemy. For this, a corps of heroic volunteer fliers led by Lt. Col. James H. Doolittle began training to attack the very heart of the Japanese Empire -- Tokyo.
To succeed, the "Tokyo Raiders" would have to launch sixteen fully loaded B-25 twin-engine medium bombers off the deck of the aircraft carrier Hornet -- something never done before -- and land at airfields in China. Through courage and luck, the raid itself went flawlessly. But bad weather, lack of fuel, and darkness worked against many of the pilots -- and for many, escaping China proved even more perilous than the mission....
This gripping eyewitness account -- hailed as "the most stirring story of individual heroism that the war] has so far produced" ("The New York Times") -- is one of the most daring missions in military aviation history: the legendary Doolittle Raid.
INCLUDES HISTORIC PHOTOS - SOME NEVER BEFORE PUBLISHED

To quote Einstein himself, this slim volume was "intended, as far as possible, to give an exact insight into the theory of Relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics." Despite his formidable intellect, Einstein writes in a clear and engaging style, using familiar examples to illustrate his theories and their surprising conclusions. Anyone with a curiosity about the man, and his often misquoted theories, would do well to settle down with this book in a comfortable chair, and shut the door - you will need to think and imagine hard to keep up with Einstein Delve into the world of the infitinely small, infinitely large, and lightning fast, and at least scrape the surface of these two great concepts which laid the foundations for atomic, nuclear and quantum physics in the following decades, and made space flight and modern astronomy possible.
