Polymeric crystals are more complex in nature than other materials' crystal structures due to significant structural disorder present. The only comprehensive reference on polymer crystallization, Handbook of Polymer Crystallization provides readers with a broad, in-depth guide on the subject, covering the numerous problems encountered during crystallization as well as solutions to resolve those problems to achieve the desired result. Edited by leading authorities in the field, topics explored include neat polymers, heterogeneous systems, polymer blends, polymer composites orientation induced crystallization, crystallization in nanocomposites, and crystallization in complex thermal processing conditions.

A book from the stand-up mathematician that makes math fun again! Math is boring, says the mathematician and comedian Matt Parker. Part of the problem may be the way the subject is taught, but it's also true that we all, to a greater or lesser extent, find math difficult and counterintuitive. This counterintuitiveness is actually part of the point, argues Parker: the extraordinary thing about math is that it allows us to access logic and ideas beyond what our brains can instinctively do—through its logical tools we are able to reach beyond our innate abilities and grasp more and more abstract concepts. In the absorbing and exhilarating Things to Make and Do in the Fourth Dimension, Parker sets out to convince his readers to revisit the very math that put them off the subject as fourteen-year-olds. Starting with the foundations of math familiar from school (numbers, geometry, and algebra), he reveals how it is possible to climb all the way up to the topology and to four-dimensional shapes, and from there to infinity—and slightly beyond. Both playful and sophisticated, Things to Make and Do in the Fourth Dimension is filled with captivating games and puzzles, a buffet of optional hands-on activities that entices us to take pleasure in math that is normally only available to those studying at a university level. Things to Make and Do in the Fourth Dimension invites us to re-learn much of what we missed in school and, this time, to be utterly enthralled by it.

In his most important book since Taking the Quantum Leap, Fred Alan Wolf, Ph.D., explains how our understanding of time, space, and matter have changed in just the last few years, and how with these new ideas we have a glimpse into the "mind of God." Making comparisons to Hindu Vedic and Judeo-Christian cosmology, Dr. Wolf explains how the universal command of the Deity "Let there be light" now takes on a new scientific meaning: Everything is literally made of light and the reader will learn how quantum physics proves this is so. Contains 70 b&w illustrations.

Authored by the originator of the standard nomenclature for this spectrum of disorders, Congenital Heart Disease: A Clinical, Pathological, Embryological, and Segmental Analysis discusses the history, anatomic features, and physiologic consequences of CHD—in one authoritative resource. The Van Praagh approach to the segmental classification of CHD, developed and implemented by Dr. Richard Van Praagh in the 1960s at Boston Children’s Hospital, remains widely used today, facilitating communication among radiologists, cardiologists, surgeons, and pediatricians who are involved in the diagnosis, characterization, and management of this disease. This unique atlas offers complete coverage of the ubiquitous Van Praagh “language of CHD, including the signs, symptoms, and clinical manifestations of malpositioned, malformed, or absent cardiovascular chambers, vessels, and valves using traditional as well as state-of-the-art technology. Based upon the systematic, widely accepted Van Praagh system of three-part notation used to succinctly describe the visceroatrial situs, the orientation of the ventricular loop, and the position and relation of the great vessels. Demonstrates how the Van Praagh approach facilitates interpreting and reporting findings through cardiac imaging with CT, MR, and ultrasonography, including fetal cardiac imaging. Presents the pathologic anatomy that pediatric and adult cardiologists, radiologists, and echocardiographers need to understand in order to make accurate diagnoses in complex congenital heart disease; as well as the pathologic anatomy that interventionists, pediatric cardiac surgeons, and adult congenital heart surgeons need to know in order to manage their patients successfully. Features more than 550 high-quality images to help you visualize and recognize malformations. Shares the knowledge and expertise of a world-renowned authority on congenital heart disease—a master teacher and the originator of the Van Praagh segmental classification system. Explores the synergy between the various disciplines who manage patient care, including surgeons, radiologists, cardiologists, pathologists, and pediatricians. Enhanced eBook version included with purchase. Your enhanced eBook allows you to access all of the text, figures, and references from the book on a variety of devices.

This is a brief but comprehensive book covering the set of EMC skills that EMC practitioners today require in order to be successful in high-speed, digital electronics. The basic skills in the book are new and weren’t studied in most curricula some ten years ago. The rapidly changing digital technology has created this demand for a discussion of new analysis skills particularly for the analysis of transmission lines where the conductors that interconnect the electronic modules have become “electrically large,” longer than a tenth of a wavelength, which are increasingly becoming important. Crosstalk between the lines is also rapidly becoming a significant problem in getting modern electronic systems to work satisfactorily. Hence this text concentrates on the modeling of “electrically large” connection conductors where previously-used Kirchhoff’s voltage and current laws and lumped-circuit modeling have become obsolete because of the increasing speeds of modern digital systems. This has caused an increased emphasis on Signal Integrity. Until as recently as some ten years ago, digital system clock speeds and data rates were in the hundreds of megahertz (MHz) range. Prior to that time, the “lands” on printed circuit boards (PCBs) that interconnect the electronic modules had little or no impact on the proper functioning of those electronic circuits. Today, the clock and data speeds have moved into the low gigahertz (GHz) range.

A thorough introduction to solar physics based on recent spacecraft observations. The author introduces the solar corona and sets it in the context of basic plasma physics before moving on to discuss plasma instabilities and plasma heating processes. The latest results on coronal heating and radiation are presented. Spectacular phenomena such as solar flares and coronal mass ejections are described in detail, together with their potential effects on the Earth.
