Since the publication of the first edition 10 years ago, significant developments have occurred in the use of admixtures in concrete. Eight new chapters and a full update of the preceding 10 chapters bring this book up to date; reflecting the relative advances made in the science and technology of different groups of admixtures. The increased role and development of admixtures in concrete technology is evidenced by a number of conferences, publications, and novel admixtures available in the market place. These developments in the field caused the modification of many chapters in the First Edition in order to reflect the advances. Although individual chapters refer to standards and specifications of admixtures, those only interested in the standards or techniques used in investigating admixtures will find the second chapter (Research Technologies, Standards, and Specifications) useful. Admixtures are not as inert as may be presumed. They may chemically interact with the constituents of concrete and affect the properties of the fresh and hardened concrete and its durability. The third chapter deals with these aspects. It was important to devote a chapter to recent attempts in developing new admixtures.

This publication will be useful to many readers including: technologists, practitioners, engineers, architects, concrete manufacturers, material scientists, cement scientists, and students.

Measuring the long-term durability of new types of concrete and concrete technologies is crucial to their acceptance in the marketplace. This long-needed handbook of analytical techniques provides a complete reference to the cutting-edge procedures used to test today's innovative materials.
Ranging from chemical and thermal analysis, to IR and Nuclear Magnetic Resonance spectroscopy, to Scanning Electron Microscopy, x-ray diffraction, computer modeling and more, the book provides first-hand explanations of modern methodsucontributed by 24 leading scientists, many of whom actually developed or refined the techniques. The book includes many analytic techniques, applied to a wide range of organic, inorganic and composite materials and additives.
Perfect for practitioners, students, and professional standards writers, the handbook is highly useful for scrutinizing materials in a variety of environments. It takes into account the many factors that affect the qualities of concreteutemperature, pore and pore-size distribution, surface area, and exposureugathering diverse evaluation methods into one convenient resource."

In this landmark work, V. S. Ramachandran investigates strange, unforgettable cases from patients who believe they are dead to sufferers of phantom limb syndrome. With a storyteller s eye for compelling case studies and a researcher s flair for new approaches to age-old questions, Ramachandran tackles the most exciting and controversial topics in brain science, including language, creativity, and consciousness."

Neuroscientist V.S. Ramachandran is internationally renowned for uncovering answers to the deep and quirky questions of human nature that few scientists have dared to address. His bold insights about the brain are matched only by the stunning simplicity of his experiments -- using such low-tech tools as cotton swabs, glasses of water and dime-store mirrors. In Phantoms in the Brain, Dr. Ramachandran recounts how his work with patients who have bizarre neurological disorders has shed new light on the deep architecture of the brain, and what these findings tell us about who we are, how we construct our body image, why we laugh or become depressed, why we may believe in God, how we make decisions, deceive ourselves and dream, perhaps even why we're so clever at philosophy, music and art. Some of his most notable cases:

• A woman paralyzed on the left side of her body who believes she is lifting a tray of drinks with both hands offers a unique opportunity to test Freud's theory of denial.
• A man who insists he is talking with God challenges us to ask: Could we be "wired" for religious experience?
• A woman who hallucinates cartoon characters illustrates how, in a sense, we are all hallucinating, all the time.

Dr. Ramachandran's inspired medical detective work pushes the boundaries of medicine's last great frontier -- the human mind -- yielding new and provocative insights into the "big questions" about consciousness and the self.

This comprehensive book containing essential information on the applicability of thermal analysis techniques to evaluate inorganic and organic materials in construction technology should serve as a useful reference for the scientist, engineer, construction technologist, architect, manufacturer, and user of construction materials, standard-writing bodies, and analytical chemists. The material scientists at the National Research Council of Canada have established one of the best thermal analysis laboratories in the world. Various types of thermal analysis techniques have been applied successfully to the investigation of inorganic and organic construction materials. These studies have provided important information on the characterization of raw as well as finished materials, quality control, quantitative estimation, interrelationships between physical, chemical, mechanical, and durability characteristics. Information on the application of thermal analysis to construction materials is dispersed in literature and hence the IRC scientists embarked on producing a handbook, the first of its kind, incorporating the latest knowledge available in this field of activity. Almost all important construction materials have been included.

The present day is witnessing an explosion of our understanding of how the brain works at all levels, in which complexity is piled on complexity, and mechanisms of astonishing elegance are being continually discovered. This process is most developed in the major areas of the brain, such as the cortex, thalamus, and striatum. "The Claustrum" instead focuses on a small, remote, and, until recently, relatively unknown area of the brain. In recent years, researchers have come to believe that the claustrum is concerned with consciousness, a bold hypothesis supported by the claustrum s two-way connections with nearly every other region of the brain and its seeming involvement with multisensory integrations the hallmark of consciousness. The claustrum, previously in a humble position at the back of the stage, might in fact be the conductor of the brain s orchestra.

"The Claustrum" brings together leading experts on the claustrum from the varied disciplines of neuroscience, providing a state-of-the-art presentation of what is currently known about the claustrum, promising lines of current research (including epigenetics), and projections of new lines of investigation on the horizon.
Develops a unifying hypothesis about the claustrum s role in consciousness, as well as the integration of sensory information and other higher brain functions. Discusses the involvement of the claustrum with autism, schizophrenia, epilepsy, Alzheimer s disease, and Parkinson s diseaseCoverage of all aspects of the claustrum, from its evolution and development to promising new lines of research, including epigenetics, provides a platform and point of reference for future investigative efforts

Phantoms In The Brain, using a series of case histories, introduces strange and unexplored mental worlds. Ramachandran, through his research into brain damage, has discovered that the brain is continually organising itself in response to change. A woman maintains that her left arm is not paralysed, a young man loses his right arm in a motorcycle accident, yet he continues to feel a phantom arm with vivid sensation of movement. In a series of experiments using nothing more than Q-tips and dribbles of warm water the young man helped Ramachandran discover how the brain is remapped after injury. Ramachandran believes that cases such as these illustrate fundamental principles of how the human brain operates. The brain ‘needs to create a "script" or a story to make sense of the world, a unified and internally consistent belief system.’

Ramachandran’s radical new approach will have far-reaching effects.

John, aged sixty, suffered a stroke and recovered fully, except in one respect: although he can see perfectly, he can no longer recognise faces, even his own reflection in a mirror. Whenever Francesca touches a particular texture, she experiences a vivid emotion: denim = extreme sadness; wax = embarrassment; orange peel = shock. Jimmie, whose left arm was recently amputated, can still feel it - and it's itchy. Our brains are the most enchanting and complex things in the known universe - but what happens when they go wrong? Dr V. S. Ramachandran, 'the Sherlock Holmes of brain science' and one of the world's leading neuroscientists, has spent a lifetime working with patients who suffer from rare and baffling brain conditions. In The Tell-Tale Brain, he tells their stories, and explores what they reveal about the greatest mystery of them all: how our minds work, and what makes each of us so uniquely human.

Multisensory Perception: From Laboratory to Clinic surveys the current state of knowledge on multisensory processes, synthesizing information from diverse streams of research and defining hypotheses and questions to direct future work. Reflecting the nature of the field, the book is interdisciplinary, comprising the findings and views of writers with diverse backgrounds and varied methods, including psychophysical, neuroanatomical, neurophysiological and neuroimaging approaches. Sections cover basic principles, specific interactions between the senses, the topic of crossmodal correspondences between particular sensory attributes, the related topic of synesthesia, and the clinic.
