Detection of Drugs and Their Metabolites in Oral Fluid presents the analytical chemistry methods used for the detection and quantification of drugs and their metabolites in human oral fluid. The authors summarize the state of the science, including its strengths, weaknesses, unmet methodological needs, and cutting-edge trends. This volume covers the salient aspects of oral fluid drug testing, including specimen collection and handling, initial testing, point of collection testing (POCT), specimen validity testing (SVT), and confirmatory and proficiency testing. Analytes discussed include amphetamines, cannabinoids, cocaine, opiates, phencyclidine, cannabimimetics, and miscellaneous drugs.

This practical guide helps users turn knowledge into practice, moving logically from an outline of the problem, to the evaluation of the appropriateness of oral fluid as a test medium, and finally to a consideration of detection methods and their validation and employment.

Compares different collection and testing systems to assist readers involved in clinical or forensic practice in selecting oral fluid as the matrix of choice Provides a sound basis for the detection of drugs and their metabolites in oral fluid and the interpretation of both positive and negative Places the need, or lack thereof, for specimen validity testing and confirmation testing in context with the purposes of oral fluid testing Describes drugs and drug classes that can be tested, along with useful information on a patient/donor's drug status

In 1961, pilot Robert M. White flew a hypersonic rocket-powered airplane six times faster than the speed of sound and higher than 300,000 feet above the Earth's surface. This is his story. Tracing his childhood on the rough streets of Manhattan during the Depression, his years as a pilot and POW during World War II, his service in Korea and Vietnam and his rise as an experimental test pilot in the Air Force, this autobiography is a testament to the role of persistence and excellence in the life of a man whose aeronautical feats are now legend. It is the portrait of an extraordinary man in pursuit of the American dream and a glimpse into a remarkable time in America's aviation history.

Quantum Theory of Magnetism is the only book that deals with the ohenomenon of magnetism from the point of view of "linear response". That is, how does a magnetic material respond when excited by a magnetic field? That field may be uniform, or spatially varying, static or time dependent. Previous editions have dealt primarily with the magnetic response. This edition incorporates the resistive response of magnetic materials as well. It also includes problems to text the reader's (or student's) comprehension.

"Quantum Theory of Magnetism" is the only book that deals with the phenomenon of magnetism from the point of view of "linear response".

Previous editions have dealt primarily with the magnetic response. This edition incorporates the resistive response of magnetic materials as well. It also includes problems to test the reader's (or student's) comprehension. The rationale for a book on magnetism is as valid today as it was when the first two editions of Quantum Theory of Magnetism were published. Magnetic phenomena continue to be discovered with deep scientific implications and novel applications. Since the Second Edition, for example, Giant Magneto Resistance (GMR) was discovered and the new field of "spintronics" is currently expanding. Not only do these phenomena rely on the concepts presented in this book, but magnetic propertiesare often an important clue to our understanding of new materials (e.g., high-temperature superconductors). Their magnetic properties, studied by susceptibility measurements, nuclear magnetic resonance, neutron scattering, etc. have provided insight to the superconductivity state.This updated edition offers revised emphasis on some material as a result of recent developments and includes new material, such as an entire chapter on thin film magnetic multilayers. Researchers and students once again have access to an up-to-date classic reference on magnetism, the key characteristic of many modern materials.
