This book provides a new, more accurate and efficient way for design engineers to understand electromagnetic theory and practice as it relates to the shielding of electrical and electronic equipment. The author starts by defining an electromagnetic wave, and goes on to explain the shielding of electromagnetic waves using the basic laws of physics. This is a new approach for the understanding of EMI shielding of barriers, apertures and seams. It provides a reliable, systematic approach that is easily understood by design engineers for the purpose of packaging the electrical and electronic systems of the future. This book covers both theory and practical application, emphasizing the use of transfer impedance to explain fully the penetration of an electromagnetic wave through an EMI gasketed seam. Accurate methods of testing shielding components such as EMI gaskets, shielded cables and connectors, shielded air vent materials, conductive glass and conductive paint are also covered. Describes in detail why the currently accepted theory of shielding needs improvement. Discusses the penetration of an electromagnetic wave through shielding barrier materials and electromagnetic interference (EMI) gasketed seams. Emphasizes the use of transfer impedance to explain the penetration of an electromagnetic wave through an EMI gasketed seam. The definition of an electromagnetic wave and how it is generated is included. Chapter in the book are included that reinforce the presented theory.

Report No. 147 (2004) presents recommendations and technical information related to the design and installation of structural shielding for facilities that use x rays for medical imaging. The purpose of structural shielding is to limit radiation exposure to employees and members of the public. The information supersedes the recommendations that address such facilities in NCRP Report No. 49, Structural Shielding Design and Evaluation for Medical Use of X Rays and Gamma Rays of Energies Up to 10 MeV, which was issued in September 1976. NCRP Report No. 147 includes a discussion of the various factors to be considered in the selection of appropriate shielding materials and in the calculation of barrier thicknesses. The Report presents the fundamentals of radiation shielding, discusses shielding design goals for controlled and uncontrolled areas in or near x-ray imaging facilities and defines the relationship of these goals to the NCRP effective dose limits for radiation workers and members of the public. The Report includes a detailed discussion of the recommended shielding design methodology for x-ray imaging facilities and provides an extensive collection of shielding data and sample shielding calculations for various types of x-ray imaging facilities. The Report is mainly intended for those individuals who specialize in radiation protection. However, it will also be of interest to architects, hospital administrators and related professionals concerned with the planning of new facilities that use x rays for medical imaging.

For fans of Sorcery of Thorns and Furyborn comes a thrilling new fantasy about a kingdom ravaged by war, and the princess who might be the key to saving not only those closest to her, but the kingdom itself, if she reveals the very secret that could destroy her. The kingdom of Hálendi is in trouble. It's losing the war at its borders, and rumors of a new, deadlier threat on the horizon have surfaced. Princess Jennesara knows her skills on the battlefield would make her an asset and wants to help, but her father has other plans. As the second-born heir to the throne, Jenna lacks the firstborn's--her brother's--magical abilities, so the king promises her hand in marriage to the prince of neighboring Turia in exchange for resources Hálendi needs. Jenna must leave behind everything she has ever known if she is to give her people a chance at peace. Only, on the journey to reach her betrothed and new home, the royal caravan is ambushed, and Jenna realizes the rumors were wrong--the new threat is worse than anyone imagined. Now Jenna must decide if revealing a dangerous secret is worth the cost before it's too late--for her and for her entire kingdom. A Whitney Award Nominee "A gorgeous fantasy that captivates from beginning to end, and a fierce heroine every reader will root for."--KATHRYN PURDIE, #1 New York Times bestselling author of Burning Glass and Bone Crier's Moon "Beautiful writing, wondrous world building, and enchanting characters.
