The Basics of Polymers is written exclusively about chemical methods of polymer testing aimed at producing a high degree of manufacturing and quality control of polymer products. Polymer testing has assumed importance for industries dependent on polymers and additives as key product components. The text is intended to serve as a handbook for students, engineers, and people involved in polymer synthesis and laboratory work. This book provides information on identification and characterization of polymers by chemical methods. Specifically aimed at graduate-level students, its style of presentation is practical, making it easier to grasp. The author hopes this book will encourage and foster continuing method development and application of chemical methods for characterizing polymers. Education and training of people being of paramount importance, it is also valuable to all educators/processors as a tremendous resource that answers commonly asked questions.
Science teachers come in many varieties, but they share a common goal: to nurture learners. Over the past decade, we have learned a great deal about how to do this effectively. Of all this new (and some not so new) knowledge, what strikes me as most important is that learning occurs best within a context. Still, as obvious as that may seem, it is relatively rare in our high school science classrooms. The problem, of course, is that it is not easy to create a learning experience with hands-on relevance to the science under discussion. Science teachers, in addition to not having the the time, for the most part do not have the expertise or readily available resources. The solution lies in finding ways to bring scientists into the teaching/learning equation. Scientists teamed with teachers and their students represent a very real and rich opportunity to involve students in real science as practiced. Imagine a research book that gives examples of honest, science-research experiences for science-oriented students. What's more, imagine a book that includes examples where students are collaborating with scientists from all over the world on research projects, in person or via the Internet. Internet Linksfor Science Education does just that. It explores the role of the Internet and technol ogy in working student-scientist partnerships.
This book explicates the optical controls of antiferromagnetic spins by intense terahertz (THz) electromagnetic waves. The book comprises two key components: (1) the experimental demonstration of the enhancement of a THz magnetic field using a split-ring resonator (SRR) and (2) the control of the direction of magnetization by using the enhanced THz magnetic field to break the symmetry of optically-induced phase transition. These make up the first step leading to future spintronics devices. In the beginning of the book, the author reviews the basics of the ultrafast laser and nonlinear optical techniques as well as the previously achieved experiments to control spin dynamics by THz magnetic fields. In this context, a new experimental protocol is described, in which electron spins in a ferromagnetic material are redirected at the unprecedented level in cooperation with the enhanced THz magnetic field. Subsequently, the author demonstrates that the THz magnetic field is significantly amplified as a nearfield around the SRR structured metamaterial, which is implemented by measuring spin precession in a solid. At the end, the author presents the key experiment in which the amplified THz magnetic nearfield is applied to the weak ferromagnet ErFeO3 along with the femtosecond near-infrared pulse, demonstrating the successful control of symmetry breaking of the spin system due to coherent control of the optically-induced spin reorientation phase transition pathways. The comprehensive introductory review in this book allows readers to overview state-of-the-art terahertz spectroscopic techniques. In addition, the skillful description of the experiments is highly informative for readers in ultrafast magnonics, ultrafast optics, terahertz technology and plasmonic science.

At this very moment the most ambitious scientific experiment of all time is beginning, and yet its precise aims are little understood by the general public. This book aims to provide an everyman's guide for understanding and following the discoveries that will take place within the next few years at the Large Hadron Collider project at CERN. The reader is invited to share an insider's view of the theory of particle physics, and is equipped to appreciate the scale of the intellectual revolution that is about to take place. The technological innovations required to build the LHC are among the most astonishing aspects of this scientific adventure, and they too are described here as part of the LHC story. The book culminates with an outline of the scientific aims and expectations at the LHC. Does the mysterious Higgs boson exist? Does space hide supersymmetry or extend into extra dimensions? How can colliding protons at the LHC unlock the secrets of the origin of our universe? These questions are all framed and then addressed by an expert in the field. While making no compromises in accuracy, this highly technical material is presented in a friendly, accessible style. The book's aim is not just to inform, but to give the reader the physicist's sense of awe and excitement, as we stand on the brink of a new era in understanding the world in which we all live.
The functional anatomy of human somatosensory cortex is of both scientific and clinical interest. Scientifically, it provides insights in information processing in the human brain. Clinically, it helps to avoid neurological deficits by sparing essential brain regions during neurosurgical procedures adjacent to central fissure. In the present study the functional organization of the human somatosensory cortex was investigated with electrophysiological techniques using a combined approach of cortical stimulations and somatosensory evoked responses on electrocorticography, scalp-EEG, and magnetoencephalography. The spatiotemporal structure of the evoked response was studiedwith biophysical modeling techniqueswhich allowed identification of the three-dimensional intracerebral location, time activity, and interaction of the neuronal sources activated following peripheral somatosensory stimulation. Furthermore, the somatotopic organization ofhand and lip somatosensory cortex was investigated. The relative value of invasive (cortical stimulations and electrocorticography) and non-invasive (scalp-EEGand magnetoencephalography) was assessed. The combined use ofscalp-EEG and magnetoencephalography was useful to increase non-invasive localization accuracy. I want to thank several people who significantly contributed in completion of the present work.

The electric dipole moment (EDM) challenge measures a non-zero proton EDM value and this book suggests how the challenge can be met. Any measurably large proton EDM would violate the standard model. The method to be employed uses an intense beam of 'frozen spin' protons circulating for hour-long times in a storage ring 'trap'. The smallness of EDMs allows them to test existing theories, but also makes them hard to measure. Such EDM experiments are inexpensive, at least compared to building accelerators of ever-greater energy.

Communication is not always through sound or language. Much can be said with gestures and movement of eyes. In fact, more often than not, it is the body language that 'says' more than words. Now discover all the finer points and nuances of body language in this masterly work. How does a thumb gesture display dominance, superiority and aggression? How does dilatation of eyes send a romantic signal? What does a sideways glance indicate? Given these incredible insights, the book can prove to be of immense use for professionals like advocates, doctors, policemen, judges, salesmen, politicians, businessmen, executives, bureaucrats and customers, etc. in understanding the thought process reverberating through the mind of a person sitting/standing in front of them.
This book aims to provide an introduction to the major techniques of chemoinformatics. It is the first text written specifically for this field. The first part of the book deals with the representation of 2D and 3D molecular structures, the calculation of molecular descriptors and the construction of mathematical models. The second part describes other important topics including molecular similarity and diversity, the analysis of large data sets, virtual screening, and library design. Simple illustrative examples are used throughout to illustrate key concepts, supplemented with case studies from the literature.
This book introduces the reader to the power of observation before,
and sometimes instead of, experimental manipulation in the study of
animal behavior. It starts with simple and easily accessible
methods suitable for student projects, before going on to
demonstrate the possibilities that now exist for far more
sophisticated analyses of observational data. At a time when animal
welfare considerations are attracting political as well as
scientific debate, the potential for non-intrusive studies on
animals is being increasingly recognized. Observation emerges as a
valuable alternative approach, often yielding highly informative
results in situations (such as on zoos, farms or for wild animals)
where more invasive experimental techniques would be undesirable,
unethical or just plain impossible. However, to justify its place
alongside experimentation as a rigorous scientific method,
observation needs to be just as disciplined and systematic and have
just as much attention paid to project design in the way that
observations are made and recorded.
